THE LANCASTER PRESS, INC., Lancaster, Pa. PLATE 1 ENTOMOLOGICAL NEWS VOL. LXII JANUARY, 1951 No. 1 DEDICATION Dedicated to DR. PHILIP POWELL CALVERT, Professor Emeri- tus of Zoology at the University of Pennsylvania and Editor Emeritus of ENTOMOLOGICAL NEWS, this volume celebrates the 80th anniversary of his birth. Many of our more recent readers will perhaps not understand the importance that we attach to this anniversary. Indeed it makes us feel definitely unseasoned to reflect upon the fact that here is a man who was associated with the Advisory Committee which helped plot the course of this publication at its founding over 60 years ago. From 1893 to 1910 Dr. Calvert was Associate Editor of the XKWS, and its Editor from 1910 to 1943, a total of 51 years. It will thus become at once apparent that no other individual can have had so much to do with the long success that this journal has enjoyed. At the University of Pennsylvania Dr. Calvert was an instructor from 18 ( )2 to 1907 and professor from 1907 until his retirement from active teaching in 1939, and at the Academy of Natural Sciences of Philadelphia he has been actively associated with publication and other affairs for half a century. East July, with the permission of Dr. Calvert, invitations were sent to odonatologists, correspondents of his over the world, to contribute short scientific papers to this Anniversary Volume. These letters brought warm expressions of regard for Dr. Cal- vert, together with a number of manuscripts for publication. Consequently this volume will be well and appropriately sea- .soned with papers on a subject to which he devoted so much ot his time and labor. 1 2 ENTOMOLOGICAL NEWS | Jan., '51 TO DOCTOR PHILIP POWELL CALVERT Editor Emeritus of ENTOMOLOGICAL NEWS OCTOGENARIAN ODONATOLOGIST GENEROUS COLLEAGUE COUNSELOR AND FRIEND We, your co-workers on Odonata salute you and, at the opening of your 8th Decade, tender you our warmest congratu- lations. For most of us your "Catalogue of the Odonata of the Vi- cinity of Philadelphia, with an Introduction to the Study of this Group of Insects" was our first textbook of the Order. It still is one of our most dependable reference works, and a model for conciseness of statement, and firm biological background. You have been the largest contributor to precise knowledge of the species of North American Dragonflies (as is well shown by the list of your publications hereinafter presented) ; and our present knowledge of the Neotropical Odonate fauna has grown directly from your Odonate Section in "Biologia Centrali- Americana" and your companion South American contributions in the "Annals of the Carnegie Museum." This taxonomic work you broadened and enriched in the book (jointly prepared by your talented wife, Amelia Smith Calvert and yourself), "A Year of Costa-Rican Natural History" ; also by your subse- quent life-history papers on particular Costa-Rican species. No one else has done so much or so well. For 33 years you edited our most eagerly awaited entomologi- cal periodical. You have made the pages of the "!\ T EWS" serve our needs, helping us to keep abreast of the progress of our chosen science ; helping also other entomologists the world around. Your editorial criticisms have been keen, constructive and helpful, and always kindly administered. Your contributions to the science of entomology have come in a steady stream that still is strongly flowing. Wherefore, we greet you with great respect and with affectionate regard; and w r e hope that you may long continue with us as Co-laborer, Counselor and Friend. JAMES G.

XEEDHAM While I was reviewing the North American species of Ophio- gomphns for a new Manual, Dr. Calvert sent me for study a pair of undetermined specimens from the collection of the Academy of Natural Sciences of Philadelphia. When I re- ported to him that they represent a new species, he told me to descrihe them, and that I now do herewith. This generous aid enables me to make my coverage of the New World species more complete. Ophiogomphus edmundo n. sp. This is a greenish species, distinctly striped with brown on the thorax, and with a blackish abdomen. The face is pale greenish or yellowish-green, with a narrow line of pale cinnamon brown on the hair-fringed front margin of the labrum. The top of the head is black, darkest across the preocellar crossband, be- coming paler brown behind the postocellar ridge. The anten- nae are black, the stout basal segment tipped with a narrow ring of white. The occiput is yellowish, its crest fringed with rather long blackish hair. The middorsal stripe of the synthorax is well defined, divided full length by the yellow of the carina. In front it is widened a little at the yellow collar, and at the rear it divides and spreads over the crest. Humeral and ante-humeral stripes are well separated by a narrow pale line, except at their ends. The mid- lateral stripe is present below the level of the spiracle ; the third lateral, narrow, complete and well developed. The legs are pale basally, becoming black toward the knees, and all black beyond. There is no yellow line on the tibiae ex- ternally. The wings are hyaline with brown veins, a white costa and a tawny stigma. In the hind wing there are seven or eight antenodal crossveins and there are five cells in the basal anal tri- angle of the male. The abdomen is slender along the middle segments. Beyond the paler and hairy basal segments it is smooth, blackish and 42 ENTOMOLOGICAL NEWS [Jan., '51 shining, and it has the usual middorsal and lateral markings of yellow. The middorsal stripe broadly covers segments 1 and 2, becomes narrowed to a line on 3, does not reach the apex on 4 to 7, broadens again and is reduced to half-length on 8, and to a round basal spot on 9. Segment 10 is mostly yellow ; append- ages yellow. The superior appendages of the male viewed from above are broadly widened at the base by a pair of opposed conical teeth that almost meet on the middle line under a slight prolongation of the dorsum of segment 10. Beyond these teeth the append- ages taper smoothly to rather sharp diverging apices. Viewed from the side they are swollen at the base, then narrowed to cylindric form, and then obliquely truncated upward to their sharp tips. There are minute rugulosities on the upward slope near the end. The inferior appendage is about equal in length to the superiors. Viewed from the side it is angulated at mid- length and slopes downward beyond the angle to its up-turned tips. Viewed from beneath, its broad end is cleft by a U-shaped notch that is deeper than it is wide. Its up-turned outermost angles are outspread just a little more widely than the tips of the superior appendages, so that they -are hardly visible from above. The hamules of the single male available are not fully visible, but their tips are black and shining, and enough of the posterior one is seen to show that on its front margin there is no angulation, but only a long convex slope. The female associated with the male is similar in coloration and somewhat larger. The brown middorsal stripe of the thorax is less widely divided by the yellow of the carina, but the other markings are much as in the male. There are no horns on the top of the occiput, but there is a pair on the rear side, wide apart and close to the margin of the eye. They are very small, black, blunt and crumpled in appearance. Length: <^45 mm., $48; abdomen ^31. $34; hind winj; <$ 24, $ 29. This species is nearest aspcrsits Morse, from which it differs in having better defined stripings of the thorax. The male su- perior appendages are not swollen in the middle as in that spe- lxii| ENTOMOLOGICAL NEWS 43 cies, nor are they so deeply rugose on their beveled end. The two opposed teeth, close-set under the middorsal tip of segment 10, are much sharper and better exposed to view; in aspcrsns they are blunt ; hitherto they seem to have been overlooked. The inferior appendage is longer and much more deeply and narrowly cleft than in aspcrsns, and its tips are more widely outspread. The subgenital plate of the female is similar to that in aspcrsns, but perhaps a little longer. In the color pattern of the abdomen the two species appear almost alike. Holotypc c?. "N. C."

Two New South American Aeshnidae (Odonata) By D. E. KIMMINS, Department of Entomology, British Museum (Natural History) Examples of the genus Xcnracsclina Selys are infrequent in collections. During examination of some unidentified material in the McLachlan collection, five specimens of this genus were found. Four of these appear to belong to an undescribed spe- cies, which I have great pleasure in naming after Dr. Philip P. Calvert, in honour of his eightieth birthday.

Vertex and occiput dark brown. Thorax dark brown, with a blue or green dorsal spot on each side narrowed at its upper end and not reaching the antealar carina. Other thoracic markings pale yellowish-green (rather faded) as follows: The antealar sinus except near the carina; 44 ENTOMOLOGICAL NEWS [Jan., '51 the meso- and meta-postnota, metanotum and spots on and be- tween the bases of the wings ; two lateral stripes, narrower than the dorsal spot, one on each mes- and metepimeron, the posterior one tapering to its lower end. Femora and tibiae reddish- brown, blackish at knees, tarsi also blackish. Abdomen brownish, tergite 1 pale, probably blue, auricles and an apical dorsal spot on 2 pale, remainder of abdomen rather dis- coloured. Abdomen slightly constricted at third segment and thence very gradually dilating to the eighth segment. Anal ap- pendages reddish-brown. Superior appendages from above with outer margin slightly convex, apex somewhat truncate. Inner margin concave near base and then straight and slightly divergent for about three-quarters of its length ; it then turns inward and at the bend carries a small peg-like projection. From this projection the lower inner margin runs in a concave, finely-serrate sweep to the lower apical angle, which is triangu- larly produced and rounded. There is a rounded median keel on the upper surface, and near the apex there is an elevated, rhomboidal, plate-like ridge, curving over inwards and forming the upper, inner, apical angle of the appendage. Inferior ap- pendage almost as long as superior, narrow, tapered from base to apex, hollowed and trough-like, with a truncate apex, curv- ing upward between the superior appendages. Wings hyaline, faintly obscured with brownish, particularly along the posterior margins and costal areas. Pterostigma brown, bordered with black veins. Costa dark brown, other veins black. Membranule dirty white, short. Anal angle of hind wing obtuse, the posterior margin somewhat curved for a short distance. $. The three females before me are slightly larger than the and much discoloured. There are traces of a dorsal green thor- acic spot but the lateral stripes (if present) are lost in the discolouration. Anal appendages broken in two examples, seg- ments 5-10 missing in the third. Fork of tenth sternite from side slightly curved, not forming an angle with posterior margin of sternite.

This species is closely related to A 7 ', den tig era Martin from Surinam, but (unless his figure is very inaccurate) it should be readily separable by the form of the <$ superior appendages. The second tooth-like projection on the inner margin in denti- gera is here replaced by a broad rounded lobe ; The apical dorsal ridge is larger than in dentigera and there is no acute tooth on the outer apical angle. The inferior appendage is less curved in profile. The presence or absence of the small acute tooth on the outer apical angle of the superior appendage may not be a specific character. There is in the B.M.N.H. an example which agrees in other respects with Martin's figure of A r . harpy a, but which has a small tooth on the outer angle. The figure shows this angle as rounded in dorsal aspect but slightly pointed in profile. lxii| KXTOMOLOr.ICAl. NEWS 4 l > The Lepidopterist's Society According to Frederick H.

In the next, we find hypodcnti, and epidermis cells used in re- ferring to one and the same structure. G. F. Ferris states that he began work on Chap. 5 (on the external morphology of the adult ) ten years ago but found that he could not proceed without first investigating the lower Dip- tera, which led him back to the ancestral conditions in the Ale- coptera, thence to the Neuroptera and finally to the Crustacea and even the annelids. These researches have appeared in the journal Micro entomology. Here, Dr. Ferris gives us, in his usual direct and concise style, only a brief account of some of his conclusions that differ radically from those heretofore prevalent. For example, the labrum and the clypeus represent the first two of the six head segments, the thoracic segment is developed from a tergite and a pair of limb bases (no sternal plates, typically), the hypopharynx does not exist in these flies. Chap. 6, by A. Miller, gives a very comprehensive account of the gross internal anatomy and the microscopic anatomy of the imago. Anatomical descriptions are illustrated by drawings while photomicrographs illustrate the histological account. The photos will help a person identify elements in sections but do not themselves impart as much information as drawings. In the last chapter (Chap. 7), W. F. Spencer describes the methods in use for trapping and for the laboratory culture of Drosophila. Relations to temperature, humidity and other eco- logical field data are included. This book calls to mind another monograph, the two volume work (1827 pages) on Dytisciis tnargiiialis by Korschelt and his students, published in 1924 (see ENT. NEWS 37: 24-29). Con- sidered as a treatise on the biology of a single species of insect, the older work is far more complete. Yet, in many respects, the present volume is more detailed, and the difference between the two reflects well the change that has taken place in biological research in the intervening years. Quite definitely, this bonk presents, mainly, data that were worked out because needed in recent investigations and often by people not much interested in the insect for its own sake but only as material convenient to use for researches on various aspects of the physiology of on- togeny and other fundamental biological problems, rresninably, much of the information presented will in the future continue to be useful to persons engaged in such work, or so it is Imped. In any event, it is a fine thing to have the data on record as a contribution to entomology. 1\. < '>. Scbmiedcr. XOTICK.

THE LANCASTER PRESS, INC., Lancaster, Pa. ENTOMOLOGICAL NEWS VOL. LXII FEBRUARY, 1951 No. 2 Outline of a New Classification for the Legion Lestes Selys (Order Odonata) By Lt. Col. F. C. FRASER, I. M.S., Retd., Winton, Bournemouth, Hants, England Selys, in 1862, published the first and the only monograph of the Legion Lestes which has appeared ; later the Legion became known as the family Lestidae, belonging to the suborder Zygop- tera within the order Odonata. In that monograph, Selys in- cluded five genera and 50 species but excluded three other genera which are now known to be true Lestes, viz., Perilestes Hagen, Chlorolcstcs Selys and Sytilestes Selys ; these he placed in the Legion Podagrion, now known as the family Mega- podagriidae. Since 1862 a large number of new genera has been created and a still larger number of species has been dis- covered, so that the number of the former has more than quad- rupled and the number of species trebled. Moreover, the family as a whole has acquired a new significance from a taxonomic point of view, since there is good reason to believe that the stem of the suborder Anisoptera and the whole of the recent Zygoptera (Agriidae) have had their origins in the Lestidae, that is to say, the Lestidae were the direct ancestors of the suborder Ani- sozygoptera from which all recent forms of Odonata have de- scended. From these considerations, there is no need to stress the need for a revision of the classification of the old Legion Lestes. With this in view, I have been collecting data and ma- terial for the past ten years and a comprehensive monograph is now nearing completion, but as it seems probable from the present difficulties in publication, that some time will elapse be- (61) 62 ENTOMOLOGICAL NEWS [Feb., '51 fore this work can appear, I take this opportunity to present an outline of the new classification involved. It will be seen here- after that three families are included under one superfamily for which the correct name should be Lestoidea, but unfortu- nately this name is pre-occupied by Lestoidea Tillyard, a genus in the family Mcgapodagriidac ; thus I have been compelled to employ the name Lestini for the superfamily. Superfamily LESTINI (== Legion Lestes Selys plus Legion Podagrion pars Selys) Zygopterous dragonflies of small, medium or, more rarely, large size, characterized by the elongation and production pos- teriorly of the anterior hamules of the male genitalia. Fore- and hindwings of approximately the same size and shape, with long slender petiole and usually elongate pterostigma ; nearly always (save in the most primitive species) an oblique cross- vein connecting Riii and IRiii about the middle of the wing (this vein representing the original site of a trachea which was borrowed by the intercalary from Riii). IRiii and Riv ex- hibiting a gradual lengthening towards the base of wing as traced from the more primitive to the more recent species. Family 1. PERILESTIDAE Small dragonflies with long and very slender abdomen. Vena- tion characterized by the discoidal cell approaching or actually impinging on the posterior border of wing at which point the anal vein takes origin or is compressed between the discoidal cell apex and posterior border of wing ; pterostigma quadrate, subquadrate or oval ; oblique cross vein between Riii and IRiii absent or merely represented by the basal attached portion of IRiii. Subfamily Perilestinae Discoidal cell of forewings closed at base. Radius greatly thickened especially in its basal half. ENTOMOLOGICAL NEWS 63 Kc\ to Genera of Subfamily Perilestinae 1.

Wings of males frequently marked or banded with blackish brown or opaque white ; pterostigma always more than twice as long as broad ; intercalated veins well developed ; IRiii arising at level of or widely distal or slightly proximal to subnodus; Riv arising at a variable distance proximal to or at level of subnodus. Subfamily I. Chlorolestinae Wings of males hyaline or more frequently banded with dark or blackish brown ; IRiii and Riv both taking origin from a point nearer the nodus than arculus, the former vein usually at or but slightly distal to subnodus ; anal vein leaving posterior border of wing at a point below the discoidal cell and far distal to the cross-vein Ac. 64 ENTOMOLOGICAL NEWS [Feb., '51 Key to Genera of subfamily Chlorolestinae 1.

GEIJSKES, Paramaribo, Surinam Tbe genus Misagria (Kirby 1889) has for a long time been represented by one species only, the genotype M. parana (Kirby 1889). A few years ago (1943), Kimmins - described a second species of this genus as M. bimacula from British Guiana, of which he says : "This species, which was placed, unnamed, under Misagria by McLachlan in his collection, differs in several re- spects from the genotype (M. Parana), and were more material available, it might be necessary to erect a new genus for it." During my explorations in Surinam, 1 twice collected a species of Misagria in the hilly country near the Brownsberg, about 100 km. south of Paramaribo, which proved to be not the common M. parana and which was set aside as probably new. After studying the publication of Kimmins, I was much surprised to find in it not my new species from the Brownsberg, but still another one which, however, shows some striking peculiarities in common with the Surinam species. The development of the anal loop in the hindwing and the structure of the male genitalia in both these species, as contrasted with the genotype M. parana, is especially remarkable. On the other hand, there are many points possessed in common with the genotype, so that it seems to me not necessary to create a new genus for the two discovered species in the Guianas although they do belong to a distinct 1 Part I.

In other primitive Libelluline genera as Cannaphila and Dasythcniis which are closely related to Misagria, we encounter also differences within the species, especially with regard to the length of the anal loop. For this reason I have extended the generic characters of Misagria as given below. Misagria calverti nov. spec. Male. Face yellow, labium with a median black stripe of moderate width. Outer margin of labrum finely bordered with black. Upper part of frons brown with metallic blue shining; ocellar tubercle light brown, antennae black. Occipital triangle and rear of head brown, with some yellow markings below. Prothorax brown, front and hind lobe and the dorsal median yellow, hind lobe more or less rectangular, without hairfringe on top. Pterothorax chocolate brown, crossed by yellow stripes as follows : a broad dorso-median stripe, which is continued be- tween the wingbases in three spots. A second stripe along the upper side of the humeral suture, running downward over the mesinfraepisternum to the middle coxa. The first band covers the lower mesepimeron, connected on top with a yellow spot situated between the humeral suture and this stripe. Hand 4 runs along the second suture, finely connected with band 3 in its upper part and crossing the suture line below the stigma, where it is widely connected with band 5 in the upper metepi- meron. Stripe 5 in turn is connected in its upper part with band 6, widely extending the lower part of metepimeron. The bands 2-6 replace largely the brown on the sides of pterothorax, with the result, that only three brow r n bands occur, viz., a large one under and along the humeral suture, a smaller second one over the stigma and a small third band in the middle or metepimeron. Poststernum yellow for the most part, the sides darkened. Legs dark brown with lighter parts on the inner side of first femora and at the apical end and first tarsus joint of hind legs. Claws with a large additional tooth at 2/3 length. Abdomen dark brown, marked on segment 15 and on segment 7 with dorso-median and lateral yellow spots, reaching in segments 4. 5 72 ENTOMOLOGICAL NEWS [Feb., '51 and 7 from base to half the segment length, in the basal segments covering a larger part. Segment 6 with a small lateral spot on each side only ; segments 8, 9 and 10 black. Appendages red- brown ; appendages superiores strongly curved in the basal half, the tips seen from the dorsal side convergent and pointed ; on the under side a triangular projection at 3/5 the length, basal side of this projection armed with a few (4) small teeth. In- ferior appendage triangular, reaching to half the distance of the projection and the end of the appendages superiores; apex rounded with two small upturned points. Wings hyaline, with a small golden wingspot at base, stigmata 19.18 brown. Antenodal crossvems ^ ,.,,-, last antenodal complete, 16.16 14.14 postnodals 1 . ... Arculus at third antenodal, triangle with one crossvein, inferior triangle in front wings two- and three-celled. One bridge crossvein in front and hind wing and two cubito-anal crossveins in hind wing. Anal loop well developed and with a definite outer angle, projecting about two cells beyond the apex of the triangle, with a forked cell at the outer angle. Discoidal field in front wing starting with a row of two cells against the triangle, in hind wing with one row of three cells, followed by a row of two cells, two cells long. Membrane small, black. Golden wingspots diffusely fading distally, in front wing reach- ing to between first and second antenodal and cubito-anal cross- vein, or one cell more ; in hind wing to near the second ante- nodal and the second cubito-anal crossvein, ending at the margin 5 cells from the anal wing base. Genitalia on second abdominal segment : anterior lamina large, triangular from the side, its anterior surface with a median fur- row, apical margin distinctly excised. Hamule larger than lamina and hind lobe, outer lobe blunt quadrate, inner lobe in the form of a small hook directed caudad, separated from the outer lobe by a small excision. Hind lobe as high as lamina, broad rounded distally. Total length 37 mm., abdomen 25 mm., hind wing 31 mm., front wing 33 mm., pterostigma 3-3.25 mm. Ixii] ENTOMOLOGICAL NEWS 73 Female.

There is a group of seven Directors that includes the presidents of the regional societies. Ixii I ENTOMOLOGICAL NEWS 77 A Note on the Derivation of the Odonate Fauna of the Island of Ceylon By F. F. LAIDLAW, Moniave, St. Lawrence, Ventnor, Tsle of Wight Ceylon is separated from the Indian mainland by a narrow strait barely 50 miles wide, and nowhere more than about 10 fathoms deep ; partly bridged moreover by shoals and islands which form the well-known "Adam's Bridge." The northern part of the island is low-lying, the south-central area mountainous, the hills rising to a height of over 7000 ft. The plains are covered with savannah, the mountains carry a dense rain-forest Both plains and mountains are of coiirse now-a-days largely under cultivation. Zoologically, the island is a Province of the Indian Subregion (roughly the lands lying to the south of the great valleys of the Indus and Ganges), and its fauna differs from that of the main- land (Indian) Province to a considerable extent. On the one hand some of the characteristic Oriental forms found in India are lacking in Ceylon, the tiger is a familiar example ; on the other Ceylon is occupied by several groups which are not found on the mainland. The Acavidae, a family of pulmonate land- mollusca, related to forms from the Seychelles and Madagascar, may serve as an instance. The dragonflies of these two Prov- inces show interesting differences, with which this note is concerned. The Indian Subregion differs from the other Subregions of the Oriental Region briefly as follows : Of the Zygoptera, the Megapodagriidae are absent, as are the Platycnemidae (except for the ubiquitous genus C opera) ; the Chlorocyphidae are poorly represented. Amongst the Ani- soptera the Aeschnidae have relatively few species and no endemic genus. Some genera of the Gomphidae and of the Libellulidae otherwise widely distributed in the Region are not represented ; one may quote Sicboldins and Lyriothemis as examples. 78 ENTOMOLOGICAL NEWS [Feb., '51 Both Provinces have special positive characters of their own. India has a radiation of 10 species of the Corduliine sub-family Idionychinae, of 6 species of Protosticta, and of about 12 spec- ies belonging to the Protoneiiridac, referred by FRASER to five endemic genera. The Epallagid genus Indophaca has three species remotely allied to a Malaysian form ; Chlorogomphus has 2 endemic species. None of these have been found in Ceylon. The only Subregional endemic genus shared by the two Prov- inces is Platysticta with which I deal below. This genus has two species in Ceylon, and one very distinct species in the ex- treme South of India. The endemic Indian species are found mainly in the Western Ghats, the long mountain range which runs for nearly 800 miles from north to south along the west coast of the Indian Penin- sula, reaching a height of over 7000 ft. in the Xilgiri and Anaimallai Hills. The range is largely covered with rain-forest, and is broken here and there by ''gaps." Of these the Palghat gap which separates the Xilgiris from the Anaimallai Hills is the most important. Isolation of the forest-dwelling dragon- flies in the several "sections" of the range has been sufficient to allow of some differentiation of the fauna of each of them. Thus Chlorogomphus campioni Fraser and Indiophaea d is par Rambur are found north of the Palghat gap only, whilst Chloro- gomphus .vanlheptera Fraser and Indophaea fraseri Laidlaw are restricted to the hills to the South. The Ghats may in fact be looked on as a chain of islands of forest and mountain separated from each other by a "sea" of low-lying, somewhat arid country ; and Ceylon may be likewise regarded as a similar but- more iso- lated island. The Ceylonese mountains are about 200 miles distant from the nearest hills of India. The number of species of dragonflies recorded from Ceylon is 100, allowing for a few doubtful entries. I have listed them below in three categories as follows : I. Species found in India, and in many cases with a wide distri- bution through the Oriental Region. Nenrobasis chinensis Linne. Lestes elata Selys. IxiiJ KXTOMOLOGICAL NEWS 79 Lcstcs pracmorsa Selys (= decipiais Kirby ) . Copera marginipes Ramlmr. Ceriagrion cerinorubellum Ranilnir. Ceriagrion coromandelianum Fabricius.

Zyxomma petiolatmn Rambur. Rhyothcinis varicgata Linne. Rhyothemis triangular is Kirby. Urothciuis signata Rambur. Macrodipla.r com Brauer. Aethriainanta brcvipcnnis Raml)ur. Ceylon shares with S. India Hylaeothcinis fruhstorferi Karsch. This genus has one other species in Borneo, and one in the N. W. Himalaya. It also shares a subspecies Sita Campion of Indothcuiis limbata Selys, the nominate species is found in Lower Burma and Malaya. I have recorded an unidentified species of Mortonagrion from the island (LAIDLAW 1924). FRASER (1936) thinks that the record of Aethriainanta brevipennis is due to an er- ror. He also suggests that Hcniicordulia asiatica Selys. and Neurothemis fulvia Drury will be added to the list. II. Representative species, presumably derived from the same stock as existing Indian species. Vest alls (Vestinus) apicalis uigrcscens Fraser. Pseudagrion rnbriceps ceylonlcnm Kirby. Paragoinphns Jicnryi Laidlaw. Cyclogomplius gynostylus Fraser. Bunnagomphus pyrarnidalis sinuatiis Fraser. Megalogouiphits ceylouicus Laidlaw. Microgoniphns lankanensis Fraser.

Ixii] ENTOMOLOGICAL NEWS 81 III. Species which do not fall into either of the above categories. Euphaea splendcns Selys. The nearest allies of this species are Malaysian forms such as varicgata Rambur. LibeUago 4 sp. A radiation of species perhaps resulting from the absence of competitor pressure. One of them, indica has, I believe, in- vaded the Indian mainland. It was first described by FRASKR (1928) as a race of lineata from S. India, where it ranges as far north as Poona. Lestes (?) oriental-is Hagen. This large species is quite unlike anything known from the Indian Province. ERASER tells me (in litt.) that it is prob- ably generically distinct from true Lestes and may be near Orolestes, a genus which is known from the Himalaya, through Indochina to Malaysia. Lestes (Ceylonolestcs) gracilis Hagen. Lestes (Ceylonolestes) divisa Selys. These species belong to a section of the genus which is mainly characteristic of Indochina. A species closely allied to gracilis is however found in S. India to the south of the Palghat gap. Drcpanosticta (Ccylonosticta) 11 sp. A radiation presumably also resulting from absense of com- petitor pressure. It is worth noting that a single species of Drcpanosticta which is probably allied to the Ceylon forms is found in the Andaman Is. where too a LibeUago occurs. Drcpanosticta is not found in Peninsular India, it occurs in Assam. Burma, Malaysia, and further east. Platysticta 2 sp. Very distinct from any other Oriental genus. I believe it to be related to the genus Palacmncma of S. America. In discussion with FRASER he admits that this is possible though he had (1938) put the latter genus in a subfamily of its own. Elattonenra 3 sp. The genus is found in India, and as far to the east as Ma- laysia. The Ceylon species are all very distinct, and do not suggest near relationship with other species. Prodasineiira sita Kirby. Regarded by FRASER as related to autumnalis Frasrr trom Burma. About 57% of the species are held in the first category. Two only of these, H \lacothcinis fruhstorjcri and Indothemis show 82 ENTOMOLOGICAL NEWS [Feb., '51 definite relationship with Indochinese or Malaysian stock. The remainder are almost all of them forms which live in low-lying country, often with a rather arid climate. Some of them are known to have migratory habits (e.g., Synipetniin jonscolombei), others have a very wide range, and probably all of them are capable of crossing from the mainland at the present time by way of Adam's Bridge either actively or passively. The second category, 18% of the species, consists of forms whose opportunities of reaching the island have been few, per- haps unique. Most of them are forest dwellers, and many show the effects of prolonged isolation marked differentiation from the parent stock. Rapid permeation of the stock has probably been helped in some cases by the relatively small area occupied by a species. 25% of the species fall into the third category. Twenty of these are definitely related to Burmese or Malayan forms. This specific percentage is exaggerated by the presence of the two ra- diations, Libellago and Drepanosticta. The three species of Elattoneitra give little help to guide us in speculating as to their origin. The two species of Platysticta (along with their Indian con- gener) are the most interesting members of the fauna. The genus is probably a surviving remnant of an ancient fauna which now has no other representatives in the area. Both S. India and Ceylon are believed to be very old land surfaces, and the survival in them of "palaeogenic" forms is quite possible. The presence of the very definite Malaysian and Indochinese elements in the fauna of Ceylon, and to a lesser degree in that of S. India would involve at the present time a migration of roughly 1000 miles across the Bay of Bengal, or an equally lengthy journey in conditions unfavourable climatically, round the coast of the Bay. Two suggestions have been made as to means which would make such a passage possible : The first is that insects may be carried passively from time to time across the Bay by the N. E. Monsoon wind, which blows steadily and persistently across the bay from the north-east dur- ing the winter months. Ixii ENTOMOLOGICAL NEWS 83 Migration of this sort could only be a rare accident, and suc- cessful colonization very exceptional. The species listed in the third category certainly suggest a random "selection." It will be noticed that all of them are Zygoptera and not strong fliers, it is possible that the possession of strong power of flight may make a passive migration less likely. Compare CALVERT'S (1942) notes on the fauna of the West Indian islands. The second suggestion, which I owe to Prof. ZEUNER, is that there was a connection between Ceylon and the Indian main- land in Pleistocene times, and that great climatic fluctuations took place in that Period when it is possible that the "equatorial rain- belt lay a little further to the North than it does today. This may have enabled species to migrate round the coasts of the Gulf of Bengal." To sum up. In addition to the ordinary lowland Oriental and Pulaeotropical fauna, about 57 % of all its Odonata, Ceylon has about I8 c /c of forms related to Indian species but differentiated more or less, by isolation. The remainder for the most part show affinities to Burmese or Malayan forms, and it is suggested that such forms have reached Ceylon either as passive immigrants carried by seasonal (Monsoon) winds, or have travelled round the coasts of the Bay of Bengal in Pleistocene times, when physical and climatic conditions differed from those of today. Lastly the Ceylon and Indian species of the genus Flatysticta are regarded as palacogenic, that is as survivals of a very ancient fauna. REFERENCES KIKBV. YY. F. 1893. J. l.inn. Soc. Lond..

Davis died in 1945 at the age of 82 he was among the last of the vanishing race of all-round naturalists. He spent a large part of his life tramping the woods and fields of Staten Island, and he was on terms of the utmost familiarity with the whole fauna and flora of the region. He was an indefatigable collector and a specialist of world-wide standing on the taxonomy of the Cicadidae. But he was more than this, and in her ex- cellent biography - Miss Abbott presents with gratifying clear- ness the eccentric, old-fashioned, keen-minded, simple, sincere, thrifty, generous, and lovable character that hundreds of people from country boys and New York business men to John Kieran and Edwin Way Teale remember with affection and. most of them, with a sense of definite obligation in one way or another. Shortly before his death, for example, Mr. Davis identified a collection of cicadas for the writer, and when he returned them he generously sent also a handsomely bound vol- ume of his papers on the group. Davis's life was identified with Staten Island ; he was an an authority on its history, its houses and antiquities, as well as on its biology ; and he was the guiding spirit and chief financial support of its Institute of Arts and Sciences. It is good to know that his extensive collections of insects in various orders are well housed on the top floor of the Museum of the Institute where they are under the care of Mr. Joseph F. Burke, and that the Davis types of numerous new species are also safe, having been deposited in the American Museum of Natural History in New York. The ancient Victorian house where Davis lived most of his life, at 146 Stuyvesant Place, still stands with its bushy dooryard and overgrown flagstones, a strange anachronism 1 Contributions from the Department of Zoology, Smith College, No. 226. - The J-ife of William T.

He kept a journal and published a book. "Davs Afield on Staten Island"; and he contributed numen>u> * papers to scientific journals, describing as new more than half of the 170 known species of North American cicadas. When he ventured away from Staten Island it was usually to attend meet- ings of entomological societies in New York, Brooklyn, and Philadelphia, or to make collecting trips on Long Island or in New Jersey. Davis was most frugal and abstemious with him- self, lunching on bits of chocolate and crackers to save a few cents, and in later years he unnecessarily feared the approach of penury ; but in his will he left $20,000 to the Historical Society and almost $100,000 to the Institute. As Miss Abbott abundantly shows in her sympathetic por- trait, Davis was always himself, a man devoid of vanity, affecta- tion, vices, or ostentation. He worked early and late in his attic museum, and he was a fountain of wisdom and knowledge to young and old within the sphere of his varied interests. En- countered in the open, he was a strange apparition : small and spare, dressed in dusty black, wearing a battered stiff straw hat ; burdened with an old army knapsack, a black umbrella, and an insect net which was often stowed under his coat behind ; hi> face adorned with a large, red nose and a straggly mustache, his eyes shining through rimless glasses an odd figure to be sure, but somehow radiating kindliness, intelligence, and an infectious joy in every aspect of nature, including people except perhaps 3 Last summer the writer made a pious pilgrimage to Stuyvesant Place where part of the Institute library is temporarily located in charge of Miss Abbott in the old Davis house (now the property of a bank) at Xc>. 146, and a few blocks down the street the Davis collections and other matters of interest are to be found in the permanent Museum building. Davis's urge for "keeping things" is well exemplified in such items as boxes containing hundreds of duplicate specimens of Psendolncanus capreolus and the like. And Air. Burke, a specialist in the study of diatoms, has beautiful specimens to show the visitor, including a series of many species taken from the cranium of Pithecanthropus credits. 86 ENTOMOLOGICAL NEWS [Feb., '51 those who set forest fires and "improve" landscapes. Several of Miss Abbott's excellent illustrations show Davis collecting in full regalia. The writer recalls an occasion when a large class of carefree students from the Biological Laboratory at Cold Spring Harbor came upon Mr. Davis in the field. He was equipped as described above and must have seemed a comic figure to the boys and girls who had never seen or heard of him before. But after lunch they got a different impression in the laboratory as he named their specimens and modestly shared other information with them. In a few minutes even the most careless felt the presence of the unusual and gave him their re- spectful attention : "He knew so profoundly what he was talking about and clothed the subject in such homely charm and interest." Davis had a wide acquaintance among the entomologists of his time including, among many. Wheeler, Leng, Olsen, Mrs. Slosson, Bequaert, Torre-Bueno and Miss Abbott traces out most of these relationships in detail, quoting from letters and from Davis's journal. But many others besides entomologists were reached by Davis's influence. When he was over seventy- he was still leading study trips of the local Bird Club and Nature Club and "going on antique hunts with members of the Historical Society." It is notable how often even the most casual ac- quaintanceship took on the tone of friendship. Many young boys became interested in science through Davis's generous efforts and in later life remained firm friends and admirers, like the soldier who wrote from Holland : "It seems forever since I have seen a man as civilized, as unforgettable." He was truly a rare and striking personality, even, as Mr. Teale says in his introduction to Miss Abbott's book, "a symbol of the good life." His was not the life for everyone, to be sure, but still it was a good life, for in it he solved in his fashion the problem all must face : how at once to follow the inner light, meet the material demands of life, and maintain a genial warmth in human relations. He loved natural woods and fields and such relics of the past as old houses and tombstones ; he was apprehensive of the complexities, conflicts, and encroachments of recent years. As his biographer says, "this was what he be- lieved in keeping things from being lost or destroyed." Ixii] ENTOMOLOGICAL NEWS 87 Current Entomological Literature COMPILED BY R. G.

Pp. x, 287, 4 colored pis.. 160 text figs. Price $5.00. To write a textbook for the beginner in entomology is a par- ticularly difficult task, as it involves selection of examples from a group which contains more species than all the rest of the ani- mal kingdom. Dr. Urquhart has been very successful in choosing insects which are well distributed on the continent, and which may be commonly seen by most interested observers. The make-up of the volume suggests that its primary func- tion is to assist the amateur to identify common insects down to the family level. The use of illustrated keys to accomplish this purpose is to be highly commended. The introductory chapters on making, preparing and housing an insect collection, and on anatomy, life history and procedures in identification are par- ticularly clear and easy to follow. The illustrations appear to be well done and quite satisfactory for the purpose intended. There is a list of general reference books for the reader who wishes to pursue the subject further. M. E. PHILLIPS. Ixii] ENTOMOLOGICAL NEWS 95 ATLAS OF SCALE INSECTS OF NORTH AMERICA. Series V. PSEUDOCOCCIDAE (Part 1). By Gordon Floyd Ferris. Stan- ford University Press, Stanford, California, Nov. 1950. Pp. vii + 278, 108 'full-page illustrations. Price $7.50. This part includes about half the known species. Unlike the earlier series by Professor Ferris, this is not "loose-leaf" but is a well bound volume and is called "Volume 5," at least on the jacket and on the cover. There is an introduction of 19 pages, and there are keys to the genera and to the species. Following the style established in the other series, the textual material is held to a minimum and each species is illustrated by a full page of reproductions of careful pen-and-ink drawings. R. G. SCHMIEDER. THE MAYFLIES OF FLORIDA. By Lewis Berner. University of Florida Press, Gainesville, Fla., 1950. xii + 267 pp., 131 illustrations. Paperbound $5.50. A systematic treatment with keys to genera and species of both the adults and the nymphs, well illustrated with many line cuts and numerous full page half-tones of adults and nymphs. In addition to the systematic and distributional data, the book gives a good general" introduction to the group, and under each species tells what is known of its ecology, its habits and its seasonal distribution. These biological data are often very de- tailed and occupy most of the page space. Altogether, this is an excellent book, well produced on coated paper. R. G. SCHMIEDER. THE CLASSIFICATION OF ANIMALS. An introduction to zoo- logical taxonomy. By W. T. Caiman, formerly Keeper of Zool- ogy, British Museum (Nat. Hist.). Methuen Monographs on Biological Subjects, Methuen and Co., Ltd., London; John Wiley, New York, 1949, vii + 54. Price $1.25. In spite of its small size, this booklet gives a remarkably clear and complete statement of the aims and methods of zoological taxonomy. It can be heartily recommended to students setting out to study insects and also to many already engaged in taxo- nomic work in order that they may profit by accepting the sug- gestions on good usage in systematic publication that are in- cluded. Among the topics taken up are the species question (together with a discussion of sub-specific categories), the genus and higher categories, nomenclature, types, the International Code, descriptions and diagnoses, keys, illustrations, measure- ments and publication. Finally, there is a short list of those books that are indispensable to the systematist. R. G. SCIIMIEDER.

THE LANCASTER PRESS, INC., Lancaster, Pa. ENTOMOLOGICAL NEWS VOL. LXII MARCH, 1951 Xo. 3 A New African Microgomphus, and Notes on Some Asiatic Types (Odonata) By CYNTHIA LONGFIELD, F.R.E.S., London The first African species to lie described belonging to the genus Microgomphus Selys was named M. schoutedeni by Lt. Col. F. C. Fraser in May 1949 (Rev. Zool. Bot. Afr., 42: 114). The insects had been taken in the Belgian Congo at Kapanga, 1 Nov. 1932, and Bambesa, 1 cubital 2 2 anal X- veins (Cuq) ^ r. 1st and 5th antenodals are the pri- maries. Arculus at the 2nd antenodal or very slightly distal. Discoidal field in forewings of 6 rows of 2 cells, in hindwings 1 row of 3 cells, then 3 rows of 2 cells. One row of cells along hind margin of forewing from base to 1A, with the exception of 3-4 double cells, 3 cells distant from the apical end. Abdomen: Glossy-black marked with citron-yellow as in fig. 1, C and D. The dorsal pattern is as follows : Segment 1 is yellow to the first transverse carina and also has a minute spot in center of the black area ; Segment 2 has a narrow anterior yellow ring and a yellow spot in the center of the black area, the tiny oreillets are also yellow ; Segments 3 and 4 resemble Segment 6 in fig. 1 , D, but with the anterior rings complete except for the black dorsal carina, also more of the larger yellow lateral spots can be seen from above ; Segment 5 exactly like Segment 6 ; Segment 7 as in fig. 1, D; Segments 8, 9, 10 black. Abdomen beneath black. Appendages yellow with black tips, 0.5 mm. in length. Length of abdominal segments: 1st, 1 mm.; 2nd, 2.5 mm.; 3rd, 0.75 mm. ; 4th, 5th and 6th, 4 mm. ; 7th, 3 mm. ; 8th, 2 mm. ; 9th, 1.75 mm.; 10th, 0.5 mm. Vulvar scale yellow, about half as long as 8th segment and shaped as in fig. 1, E. M. camerunensis is very similar to schoiitedcni in color- pattern, but can best be separated by the different shape of the occiput together with the short irregular spines, instead of a fringe of black hairs ; also by the shorter hind femora. It has a somewhat similar thoracic pattern to M. zvijaya Lieftinck (1940) from Ceylon, while the vulvar scale resembles that of M. thclyphonus Lieftinck (1929) from Java, but it has very much shorter and broader valves than in M. torqnatus (Selys, 1854) type female from India. I would here like to take the opportunity to correct two state- ments made by Lt. Col. F. C. Fraser in 1934 in volume 2 of The Fauna of British India, as to the location of 2 type specimens. Ixii, '51 | KNTOMOLOGICAL NEWS 101 The type of M. torquatits (Selys) is not in the Selys collection (Brussels), as stated on page 355, but in the British Museum (Natural History). The type of Cycloyomphns \Microgom- [>husl'\ ininusculus Selys is not lost, as stated on page 361. It was in the MacLachlan collection and is now in the British Museum (Natural History). This female is neither a Cyclo- gomphus, as now defined, nor a Microgomphus. I think it is most likely a Burmagomphits Williamson. The t\pc of Microgomphus camerunensis Longfield and the Microgomphus female from Portuguese East Africa are also in the British Museum (Natural History) having been presented by the respective collectors. Microgomphus sp. A mature female from the Inyamadzi River, Portuguese East Africa, 12.11.1948. It differs from camerunensis in being a yellower insect. The entire frons and clypeus, also nearly all the labrum are citron-yellow, with only a very narrow blackish basal band across the labrum and a faint indication of a fine black surrounding edge to the lip. The tips of the distalia are yellow in the otherwise black antennae, and the back of the head and eyes is either orange or reddish-brown. The shape, color and armature of the occiput is almost identical. The com- pound eyes meet to within 1.25 mm. and are orange? in color. The prothorax appears to be unmarked. The dorsal pattern of the thorax is similar to camerunensis, but laterally it would appear that the yellow vertical band on the metepisternum is joined below to the yellow metepimerum, leaving a large oval black patch astride the 2nd lateral suture. Legs are more yellow than black ; the hind femora measure 7 mm. It would appear that on the abdomen there is more yellow laterally, possibly continuous along the lower edge of the tergites. Beneath, the black of the sternites is somewhat pruinose. Segment 8 would seem to have some yellow laterally, but 9 and 10 are black. The light yellowish-brown anal appendages are very slightly blunter than in camerunensis, a bit longer (0.75 mm.) and without black- tips. The dimensions of the segments differ slightly : 1st, 1 mm. ; 102 ENTOMOLOGICAL NEWS [March, '51 2nd, 2.75 mm. ; 3rd, 4th and 5th, 4 mm. ; 6th, 3.75 mm. ; 7th, 3 mm. ; 8th, 2 mm. ; 9th, 1.75 mm. ; 10th, 0.5 mm. ; total length- appendages 27.5 mm. The vulvar scale is yellow and shaped as in fig. 1, F. The wings are slightly tinged all over with greenish- yellow, this may be due to age. Pterostigma reddish-brown, 3 mm. long and 0.5 mm. deep .in all wings. The cells beneath are small and variable in number, from 4 to 5%.

The 1 st and 5th antenodals are the primaries in the forewings and the right hindwing, 1st and 4th in left hindwing. The discoidal field of the forewing has 6 rows of 2 cells and the hindwing 1 row of 3 cells, then 3 rows of 2 cells. The hind margin of the forewing from base to 1A is all of single cells. From schoutedcni it is easily separated by the yellow face, the different shape and armature of the occiput, the shorter hind femora and the yellow anal appendages.

Ixii, '51 | ENTOMOLOGICAL XK\YS 103 A Note on the Persistence of a Much-Neglected Primary Antenodal Cross Vein in the Order Odonata 1 By HSIU-FU CHAO - Department of Entomology, University of Massachusetts, Amherst, Massachusetts During the progress of a study of Chinese gomphine dragon- flies I have noticed an antenodal cross vein which has remained heretofore unreported. This vein is'herehy called the basal pri- mary antenodal cross rein and is denoted by Ax,, since it is basacl of the other two previously recognized primary antenodals. Ax, and Ax,. This vein has been shown in the drawings illustrating the wing bases of the dragonflies by Snodgrass (1908, 1930, 1935), but is not named or discussed. In order to facilitate the discussion of Ax,, a description of the costal margin of the dragonfly wing seems necessary. In 1948 Fraser stated : "If the nodal region of the wing of any dragon- fly be observed under a moderately high-powered microscope, the subcostal vein will be seen to approach the nodus and then make a distinct curve anteriorwards towards the costal margin, at which level it straightens out again and runs along the lower margin of the costal border of the wing as a distinct tubular structure." Thus under this interpretation, followed here, the part basal to the nodus is C and the part distal to the nodus is a portion of Sc. The flattened costal vein is gradually twisted a short distance 1rom the base of the wing. Its basal portion is broad, dorso- ventrally flattened, dorsally longitudinally grooved, and ven- trally correspondingly ridged. In dorsal view an intermediary piece (Snodgrass, 1935, pp. 220-221, C) is interpolated between 1 Contribution from the Department of Kntomology of the University of Massachusetts, Amherst, Massachusetts. -I wish to express my sincere appreciation to my teacher. Dr. John K Hanson, for his invaluable guidance and helpful criticism during the progress of my study. Indebtedness is also due to my friend. Mr. George 1'. Edmunds, of the University of Utah for information from his extrn sive knowledge of \vin- venation and mechanics of inayfhY- 104 ENTOMOLOGICAL NEWS [March, '51 the extreme base of the posterior margin of C and the posterior lobe of the humeral plate. Ax,, is located at the junction be- tween the base of the posterior margin of C and the intermediary piece. It is connected with the ventral ridge of C a condition which is the same for all other costal cross veins. A part of Ax is dorsally obscured by the posterior margin of C, but its greater portion can be seen as clearly as any other veins. Structurally Ax is exactly the same as the other two veins, Axj and Ax 2 , which are strengthened by what Eraser (1937) called "strongly chitinized membrane." Each so-called chiti- nized membrane is actually formed by the fusion of two abutting lamellar veins, the costal and the subcostal cross veins. These two portions may be separated along their line of fusion when a force such as that exerted in mounting a wing on a slide is applied. It seems appropriate to point out here that another cross vein having exactly the same kind of structure is present This is a composite cross vein on the ventral surface of the wing consisting of the subcostal cross vein at the nodus and the sub- nodal cross vein. Its significance in wing mechanics has been pointed out by Eraser (1948). The membrane of the two cells basal to Ax,, is thicker than that of other cells and is tinged with brown or other colors in different species; or it may be partly transparent, as is the case in many species of gomphine dragonflies. The basal primary antenodal cross vein is the most basal of all cross veins yet discovered in odonatan \vings. Furthermore, it is the most persistent of the antenodal cross veins, being strongly developed probably in all living species of the order Odonata. The reason for its consistent occurrence may be found in the fact that the base of the costal margin is flexibly connected with the humeral plate and the intermediary piece. It seems logical then that a strong cross vein at the very base of the costal region would be most important for production of rigidity of the fore margin of the wing a condition which is very essential in the sculling type of flight. Judging from its position this vein resembles the costal brace of mayflies. However, its actual relationship with the latter Ixii, '51 | ENTOMOLOGICAL NEWS 105 vein is not certain since no sufficient evidence has been obtained regarding homologies of wing bases of mayflies and dragonflies.

QUENTIN, Richard Kralikplatz 2, Wien, Austria It is known that secondary sexual characters occur on the legs of the male Odonata : In Anisoptera the "tibial-keel" is known and in some genera modified spines as in Cordulegasteri- nae, in the genera Epigomphus l and Leptogomphus. 2 In 7.\- goptera there occur modifications on the tibiae in form of coloration and dilatation. In this suborder the modification appears, in some genera and species, as a slight whitish pruinescence on the inner side, the flexor surface, of the tibiae. This pruinescence seems to be an exudate of supra-cuticular pigmentation like the "bloom" of certain fruits. Such pigmentation occurs very frequentlv on 1 Calvert, Ent. News XIV. p. 187 (1903 I. - I.aidlaw. Malayan P.ranch J. Roy. A.S. Sue. Part II. p. 227 (192<.i. 106 ENTOMOLOGICAL NEWS [March, '51 different parts of the body of dragonflies and is known as a sign of maturity. The other kind of the modification consists of a light color on this side of the tibiae. Species with a higher degree of the modification and species with whitish legs, show, in some cases, dilated tibiae. The purpose of this modification is cleared up by the obser- vations of several authors, such as Poulton, Laidlaw, Lieftinck and Fraser ; "the males perform a kind of nuptial dance before the female, during which they make a great display of the white pulverulent flexor surface of the hinder pairs of tibiae," says Fraser. 3 In Anisoptera sexual characters of such kind are unknown. Pruinescence occurs very commonly on the thorax or other parts of the body, but never on the tibiae. The modification is found in six genera, belonging to two systematic groups : They are the Fpallaginae Laidlaw with the genera Libellago Selys (-- Microinenis Rambur), Chlorocypha Fraser, Rhinocyplia Selys, and the Platycnemididae Fraser with the genera C opera Kirby, Proplatycnemis Kennedy, Platycnemis Charp. Libellago Selys shows, in the most species, a light pruinescence on the inner side of the tibiae. The tibiae are slightly dilated in about 1/10 of their length. Unmodified tibiae occur like L. iniae Lieftinck or L. dorsocyana Lieftinck. In all six gen- era there also occur species with unmodified tibiae ; therefore, it seems that the modification has a separate origin and has de- veloped independently in each genus. Chlorocypha Fraser is closely allied to Libellago. The genera were established by Fraser 1928 for the African species of the old genus Libellago. In this genus the inner side of the tibiae is light-colored without pruinescence. C. rubida Hagen shows unmodified tibiae. C. tennis Longfield shows a green stripe on the inner side of the black tibiae, perhaps the first step of the modification. C. curta Hagen has the tibiae on the inner side light colored. C. caligata Selys has the red tibiae that are dilated 1/7 of their length. 'Lieftinck Follow, Treubia XIV, p. 386 (1934). Ixii, '51 | KXTOMOLOGICAI. \K\VS 107 In Rhinocypha Selys a pruinescence is found as in the genus Lihcllago Selys, but only the middle- and hind-tibiae are modi- fied. R. pclops Laidlaw has unmodified tibiae, R. phantasnia Lieftinck has the tibiae basally dark and distally light. The most species show a whitish pruinescence on the tibiae and the tibiae are slightly dilated ca. 1/10 of their length. In the Platycnemididae Fraser, likewise, only the middle- and hind-tibiae are modified. The same is true of the sexual char- acters on the legs of Anisoptera. It seems that the various func- tions of fore legs, like holding the food, cleaning eyes and mouth- parts, make them unusable for other adaptations. The three genera Proplatycnemis Kennedy, Platycnemis Charp, and Copcra Kirby are very closely related. Proplaty- cncmis has been separated by Kennedy 1920 ' for two species of Platvcncinis from Madagascar; Platycnemis and Copcra were once put ' in one genus. Proplatycnemis agrioides (Ris) shows the tibiae black with a bright bluish stripe on the inner side. It seems to indicate that the whitish legs of the Platycnemis have arisen from a type with black legs. The tibiae of P. agrioides are slightly dilated. In the genus Copcra Kirby, the species show orange to whit- ish tibiae. Species with unmodified tibiae also occur, such as C. iinbricata (Selys). Following Lieftinck 1940,''' C. rittata (Selys) and its subspecies show all degrees of the modification from unmodified tibiae to strongly dilated ones. The typical subspecies C. rittata rittata ( Selys ) inhabits the southern Malay States, a part of Sumatra and all Horneo. The tibiae are not noticeably dilated. Subspecies with strongly di- lated tibiae are C. rittata serapica (Selys), confined to the Xikobar Islands, and C. ritlata jarana Lieftinck from the wooded districts of south Java. It is very remarkable that both sub- species with strongly dilated tibiae inhabit rather restricted areas. Isolation seems to advance the modification. In Sumatra there are found C. ritlata rittata (Selys), C. ritlata- acntinnvgo (Kriiger) and C. imhricata ( Selys ) all with undilated tibiae. -'Kennedy, J. Ohio Sci. 21. p. 85 (1920). 5 A Manual of Dragonflies of China, p. 248 (1930). 6 Lieftinck, Treubia XVII, pp. 281-2306 (1940). 108 ENTOMOLOGICAL NEWS [March, '51 In Borneo occur C. rittata vittata (Selys) and C. rittata f>ala- vana Lieftinck, both with tibiae not noticeably dilated. In Java occur C. anniilata (Selys), C. marginipes (Rambur) and C. rittata javana Lieftinck, all with dilated tibiae. It seems that the great islands, Sumatra, Borneo, and Java, has each its par- ticular type of Copcra. Sumatra and Borneo species and sub- species without, Java species with dilated tibiae. The genus Platycneinis Charp. presents marked variations. The legs of the species are whitish, but it is probable that they are derived from a type with dark legs like Proplatycnemis Ken- nedy. The African species P. nyansana Forster shows only slightly dilated tibiae, ca. 1/10 of their length. From this type to the type with the highest degree of the modification, P. jolia- cca Selys with 1/3 dilatation, all intermediate steps can be found. In this genus the modification reached an additional degree. In some species the modification appears in the same form on the females also. In P. pennipcs Pal. the tibiae of the females are also a little dilated. In P. latipcs Selys the tibiae of the females are just as strongly dilated as in the males, ca. 1/7 of their length. The secondary sexual character has become a specific character. The development of the modification is easy to follow. The origin may show a type like Libcllaf/o or RJilnocypha with a thin pruinescence on the tibiae, more a physiological sign of maturation than a morphological character. This pruinescence can become, in some forms, a thick stratum and finally, in addi- tion, there is a dilatation of the tibiae. Chlorocypha or Platy- ciieiuis follows a different path.' The first step may be indicated by a light stripe on the inner side of the dark tibiae. Then the tibiae became a light color and dilated. In these forms dilatation reaches its highest degree. In some species, but not in the spe- cies with the most dilated tibiae, the modification appears also in the females. Thus, the development of this modification re- sembles the development of antlers in the Cervidae. In this family most genera possess antlers as sexual characters of males. Only in some primitive genera like Moschus or Hydropotes are antlers lacking. In the genus Rangijcr the sexual character has become of specific rank, and both sexes have antlers.

GLOYD, Illinois Natural History Survey, Urbana, Illinois Tin's report is based primarily on the dragonflies taken on a brief trip, sponsored by the University of Michigan, to Virginia in September 1934. It is supplemented by a list of species in the collection of the Virginia Polytechnic Institute at Blacks- burg, and by a recent collection received from R. L. Hoffman of Clifton Forge. Several species, although rather common, have not previously been reported for the state. SOUTHEASTERN RECORDS On September 1 1, 1934, after a memorable visit with Doctor and Mrs. Calvert in their home at Cheyney, Pennsylvania, H. K. Gloyd and I set forth on a collecting trip to southeastern Vir- ginia. Heavy rains had fallen during the first two weeks of September throughout most of the state and with additional rains at night, cloudy skies during most of the daylight hours, wet vegetation, and flooded streams, ponds and swamps, we found conditions for collecting dragonflies far from ideal. Our first stop was made, on the morning of September 12, at Falling Creek, 5 miles south of Richmond where we saw onlv three J Boyeria I'inosa (Say) and one male Hctaerina titia (Drury), all Hying erratically and apparently excited by the torrential waters of the flooded stream. It was not possible to get within swinging distance of these dragonflies. The Hctaerina was shot and caught as it floated downstream within reach. Our first camp was made in a grove of trees in the vicinity of Cypress Chapel, Xansemond County, near the western edge of the Dismal Swamp. A few hours of sunshine in the morning on September 13 and 14 and for most of the afternoon on the latter day furnished the only good flying weather for dragon- flies during our stay of several days. A nearby peanut field, bordered on the south and west by woods, on the north by a clearing in which sat an abandoned house, and on the west by 110 ENTOMOLOGICAL NEWS |. March, '51 a small corn patch, was frequented by Pantala flarcscens. Trained Carolina, and Soniatochlora filosa. They seemed to be feeding on small insects which arose from the heavy foliage of the peanut plants. The Somatochloras flew low except when one was near with a net. Toward evening the height of their flight kept pace with the upsurging swarms of midges and by seven o'clock in the evening the Somatochloras were at treetop level with only an occasional low flight. One male was caught while he was patrolling a road between timbered areas. Ana.v jnniits, Llbcl- litla 2'ibrans, and Erythemis simplicicollis were taken near the abandoned house and at the edge of the cornfield. A ditch along a fairly well-shaded portion of the road served as the habitat for Anowialagrion hastatiim, Ischnura posita and Nehalcnnia integricollis. A female Ischnura posita attracted my attention because she was flying about with a portion of a male abdomen still attached to her prothorax mute evidence of sudden tragedy. The dragonfly population was greatest at a nearby flooded swamp pond. On the cloudy afternoon of September 13, Lcstcs "i'if/ila.v was abundant in the cattails and marginal vegetation. Other species of Zygoptera were rare. Of the Anisoptera, Pachydiplax longipennis and Erythemis simplicicollis were rather common. The following morning was bright and warm with sunshine. At 10:00 o'clock only a few Lestcs viyila.v and dis- jiinctus were found hanging up and an occasional Enallagma was seen. About noon several species of Zygoptera, as well as Perithernis tenera and Pachydiplax longipennis, came out in considerable numbers. There were many mating pairs of Enal- lagma diibinin on the lily pads but most were too far out to reach without wading beyond one's depth. About one o'clock they began to fly toward the edge of the pond and I went in pursuit of a pair. When I again turned back toward the center of the pond, not a zygopteran was to be seen. They had all vanished as if by a common signal. I do not know whether this was due to the intensity of the hot noon-day sun or to the appearance of greater numbers of Ervthcinis and Lib ell nl a.

Small streams in the vicinity of Long Dale looked beautiful but 112 ENTOMOLOGICAL NEWS [March, '51 dragonfly life was conspicuously absent. On September 18, after a cold night, the day was warm and blessed with sunshine and a few clouds. Two hours were spent on Simpson Creek, a stream of considerable fall and swiftness, with rocky bottom and occasional spots of coarse gravel, and with many deep holes. It ranged from ten to twenty feet wide and from six inches to three or more feet deep. In the region where we visited it there was a high bank on one side and tall shrubs, frequent alders and other trees grew on the other bank. Only four specimens, rep- resenting three species, were taken but the beautiful surround- ings and the one new state record, Boyeria grafiana, made the time seem well spent. On September 19, about one mile southeast of Clifton Forge, at a turn in the highway we suddenly came upon an interesting site and stopped for about an hour to collect. Twenty or thirty feet below the road was a rather large pond approximately two- thirds as wide as, and a little longer than, a city block. The north and west sides were formed by the steep roadgrade, the east and south banks were the more sloping sides of a mountain. We worked from the west side where the vegetation was rather dense. Small willows and other first-growth trees produced overhanging limbs and made dry land collecting difficult. Water vegetation was abundant but nevertheless wading was treacherous as the pond bottom was soft and full of holes and irregularities. Enallagma civile was extremely abundant and mating pairs were seemingly flying by the hundreds. Argia -c'iolacca, Ischnura verticalis, and Sympetnnn vicinum were also mating. Erythemis siniplicicollis and Libelhtla inccsta were seen but little effort was made to collect them as they were wary and we had little time. We saw only the one Aeshna unibrosa $. The specimens we collected in Alleghany County are listed below together with those taken recently by Richard L. Hoffman (RLH) from the same county. Argia niocsta (Hagen).

Ixii, '51] ENTOMOLOGICAL NEWS 123 These three volumes, appearing under the title Micrcn (- Ants) and as a part of the series IV at Iccjt en yroeit. dc wcrcld ran dicrcn en plantcn (-- What lives and grows, the world of animals and plants), give Dutch readers a concise, popular and up-to-date account of the fascinating world of the ants. Father Raignier, already well known in myrmecological circles for his scholarly studies on ant ecology, will doubtless reach and charm a wide, new group of readers with the present work. Alyrmecologists in particular and biologists generally will surely find much of interest in Micrcn. Some of the topics treated are: nests (artificial and natural), colony founding (in- dependent and dependent ) , care of immatures, habits, trails and territories, behavior of workers, communications, orientation, olfaction, aphids and Lycaenae, myrmecophiles and keys for the determination of Dutch ants. Chapter 5 of volume 3 was written by Father Jos. van Boven. Under the title "Wat loopt daar?" this capable, young taxono- mist has presented the reader with keys to the subfamilies (4), genera (16) and species and infraspecific forms (44) of Dutch ants. Since this chapter is well illustrated, and since the formi- cifauna of Holland is small, readers with the necessary optical equipment should not experience too much difficulty in naming a good proportion of the ants that they might collect. For those readers who might wish to learn more about ants, twenty well-selected references are included in Appendix I. In this section, entitled "Wat lees ik nog meer?", the names of the following well-known authors appear : R. Brim, F. Buytendijk, H. Donisthorpe, K. Escherich, A. Forel, W. Goetsch, A. Krausse, F. Maidl, H. Schmitz, A. Starcke, E. Wasmann and W. M. Wheeler. The binding is of tough, manilla-like paper. The format is 11 by 19 cm. The paper is of good quality. The illustrations by Gerard Huysser are with few exceptions all original. These illustrations are for the most part very well done. Some of the photos are closeups of living ants ; these are exceptionally fine examples of small insect photography. There is no date of impression to be found anywhere in the three volumes. I have listed 1950 as the date of issue, however, since I received the three volumes in one package sometime during the summer of 1950. I believe that Father Raignier sent them out shortly after they appeared in print. Father Raignier, Father van Boven, the Illustrator and the publishers are to be congratulated on having produced an excep- tionally fine little work on ants. MERLE W. Wixr,.

H. Rehn This study is the result of an analytic examination of the venation of the alar organs of the recent Blattaria, or cockroaches, and presents tex- tually and by figures the results of this investigation. After an introduc- tory discussion on orthopteroid, and specifically blattoid, classifications used by previous authors, the author gives a set of tables correlating the various terms used by previous workers for blattoid venation, and after summarizing the general evolutionary tendencies shown by the individual elements of the venation, an entirely new systematic arrangement on the basis of venation is presented. The recent Blattaria are divided into five families, seventeen subfamilies and forty-three tribes, of which two families, eight subfamilies and twenty tribes are proposed for the first time. One or more representatives of each tribe are discussed in detail and both tegmen and wing of the same are figured. The alar details of sixty- seven genera and species are described and figured, of which forty-three species are the genotypes of their respective genera. One hundred and forty-one figures are given on the thirteen plates, and the bibliography includes all the papers cited in the introductory discussion.

THE LANCASTER PRESS, INC., Lancaster, Pa. ENTOMOLOGICAL NEWS VOL. LXII APRIL, 1951 No. 4 Sclerotizations in the Lateral Body Wall of the Nymphal Abdomen in Odonata By ERICH SCHMIDT, Bonn (Rhein), Mozartstr. 22, Germany In 1893, when Dr. PHILIP P. CALVERT published his well known catalogue with its important introduction, he was prob- ably the first to mention the pleura of the nymphs of dragonflies, when he stated (p. 198): "The pleura are equally well chitinized as the large terga and sterna; in the Zygoptcra they are infolded, in the Anisoptera exposed to view on the ventral surfaces." This condition was similarly described and some- what expanded by TILLYARD (1917, p. 88) : "The pleura (of the larva ) differ from those of the imago in being strongly chitinized. In the Anisoptera they form flat side-pieces to the sterna ; in the Zygoptera they are infolded. Eight pairs of abdominal spiracles are present, the eighth being the largest. Their positions near the anterior margins of the pleura, close to the terga, correspond with those of the imago." For a long time I have believed that which I expressed in my paper of 1915 (p. 100, translated) : "In the larvae of the Anisoptera, in place of the imaginal pleural folds, there are found regular pleurites that lie ventrally and laterally to the sternite, and are separated from both sternite and tergite In- conspicuous sutures. These pleurites resemble the sternites and tergites in color and they are characterized by the spiracle that lies within them. The nymphs of the Zygoptera do not show any such conditions ; the boundaries of the tergite and sternite against the pleural membranes are indistinct. In Euphaea, the lateral gills lie in the pleural membranes." This opinion concerning the condition in the larvae of Zygoptcra (125) 7 - 1951 126 ENTOMOLOGICAL NEWS [April, '51 was later verified by CARMAN (1917, p. 422) : "Each body- ring (of the larvae of Zygoptera) is without sutures but is roughly divided by the lateral carinae into sternal and tergal areas." Therefore I was somewhat astonished when, in a paper by WHEDON (1919, pi. XXI, fig. 1), I found a line (sf>ls) drawn which was explained as a sterno-pleural suture. Hence, for my own information, I made a preparation of a luxuriously coloured exuviae of Lcstcs sponsa (fig. la), in which inside of the lateral carina of segm. 48 there was visible a light, ir- regularly bounded, narrow stripe which perhaps may be con- sidered as a suture. The space between the carina (c) and this suture may be that which corresponds to the "pleurites" of anisopterous larvae ; it is a very narrow dark stripe, however, that, in accordance with its coloration, should not be as soft as neighboring parts. The conditions of these sclerites of anisopterous larvae, con- sidered hitherto to be pleurites, are illustrated in several places in the literature, for instance by CABOT (1890, pi. V, fig. 2a, for Cordulia sp.), by BERLESE (1909, fig. 403, for Aeschna grandis], WALLENGREN (1914, fig. 3, for Aeschna}, TILLY ARD (1917, fig. 29 B, for Aeschna brevistyla}, by WHEDON (1919, fig. 8, for Ana.r jnnius, 13 and 16 for Tramea Carolina, fig. 30, for Hageniiis brevistylus} , CALVERT (1929, fig. 6, 7, for Anax jnnius}, the present writer (1936, t.fig. 4a-f, lOa, b, for some European Gomphids ; 1937, t.fig. 11-14, for some Aeschna sp.). These ilustrations mostly agree in showing the supposed pleu- rites as a uniform sclerite, except WALLENGREN (p. 6, fig. 3), who figured sclerotizations of segm. 5 and 6, apparently of Aeschna grandis, and showed that in segm. 4-8 "the pleurites are divided into two plates, a small anterior episternite (fig. 3, Ep) and a greater, posterior, lower, epimente (///>) that borders upon the sternite. The episternite is, namely, situated between the anterior ends of the epimerite and the tergite." Such was the usual view twenty years ago concerning these lateral sclerites between the dorsal and ventral plates. In 1933, WEBER wrote (p. 203, translated) : "The sclerites that occur, not rarely, in the lateral membranes and that are often Ixii I ENTOMOLOGICAL NEWS 127 designated as pleurae have in reality nothing to do with thoracic pleurae (subcoxae), but are secondary formations, if they have not, indeed, been derived from the terga." Hence, it seems better not to adopt such terms as epimerite and ^rf; : .i-- ? -.'-(( * .';'/ , ;-. .. 3E -,, :-..;S tl! -^ I:' . " -*!#<;'' vl t '""jtifci f^st . -\, ; - a TEXT FIGURE 1 a.

We therefore propose for the greater sclerite, formerly named epimerite, the term "spiracular sclerite," abbreviated spir. scl., because it bears (but not in segm. 9) the spiracle; and for the smaller sclerite, formerly named episternite, the term "tri- aiii/nlar sclerite.''' abbreviated tr. scl., derived from its shape. 128 ENTOMOLOGICAL NEWS [April, '51 Before entering into a detailed comparison of these sclerites in several larvae of Anisoptera, which will show an unexpected differentiation in single families and even in genera, some gen- eral features should be mentioned : a) The tr. scl. is usually missing in segm. 9 with one excep- tion (O.vygastra, see below), and there is generally a uniform and undivided plate, without a spiracle. In Cordulcgaster, however, even this plate is absent (see below). b) Furthermore, the coloration, and correspondingly the sclerotization, decreases more and more in the abdominal seg- ments nearer the thorax so that it becomes difficult to recognize a suture separating the sclerites. Hence, we shall turn our at- tention more to the segments of the middle and caudal parts of the abdomen. c) In many specimens, especially in those dwelling on the bottom, the area near the intersegmental fold is often covered with mud that adheres so firmly between the hairs or bristles of the skin as to form a nearly insuperable obstacle to a pin used to clean the fragile surface of such a valuable skin, even after hav- ing softened it with some liquid such as alcohol or water. Hence, its practical value for use in differentiating species is doubtful, since more easily visible characters are often available. d) To date, we have compared mostly the last instars of larvae, as others were not collected. Surely, the younger stages, especially in the Libellulinac, should also be studied. 1. The following comparison was suggested especially from our wish to learn the conditions of sclerotization in the lateral body wall of the abdomen of the strange Japanese Epiophlcbia super stes (Selys), which, together with several fossils, is now considered to form a special suborder of the Odonata (HAND- LIRSCH, 1906, p. 465). The discoverey of its nymph by ESAKI, probably in 1923, gave me the idea of writing to Japanese col- leagues asking them for a statement concerning this matter, or to send me a cast larval skin. It was not until some months ago, however, that I was fortunate enough to receive two larval skins, a male and a female, both of the penultimate instar, through the kindness of that capable Japanese student SYOZIRO ASAHINA Ixii] ENTOMOLOGICAL NEWS 129 in Tokyo, to whom I am very much indebted. These skins showed at once strongly sclerotized plates quite similar to those in most Anisoptcra; scl. spir. on segm. 2-9, missing in segm. 1 and 10 (fig. Ib). Spiracles are visible on segm. 1-8. The sur- face of the ventral side is covered with numerous tubercles, and, though it seemed to be sufficiently clean, no suture separating a tr. scl. was visible. The structural conditions, however, approach the conditions found in Anisoptcra more than those in Zygoptera. 2. In general, the greatest number of tr. scl. seems to occur regularly in the nymphs of Aeschnidae, where they appear on segm. 4-8, as stated by WALLENGREN (1914, p. 6), or also on segm. 3 (fig. 2a). Variation in the segments supplied with the tr. scl. was not observed except for segm. 3, but perhaps the size of the sclerites may be somewhat different in single forms. Surely, the tr. scl. in this family are smaller than in most Lib ell u- lldac and some Goinphidac (see below). In segm. 8, the oral and inner side of tr. scl. is relatively long ; nearer to the base of the abdomen its oral side becomes gradually shorter, the outer side longer. On the anterior side of spir. scl. of Ana.v (fig. 2a) a transverse groove was observed, which was not found in Aeschna. 3. Larvae of Pctaluridae were not accessible now, and a younger larva of Phyllopctalia stictica Selys showed the tr. scl. on segm. 6-8 only, but it may exist also on the anterior seg- ments. In SCHMIDT, 1941, pi. 2, fig. 2, a full grown nymphal skin of Phenes raptor Ramb. was figured, showing the row of spir. scl. on segments 2-8 ; oblique lines visible may perhaps correspond to sutures, or may not. On the same plate, fig. 4 shows distinctly the row of spir. scl. on segments 3-9 of a last instar exuviae of Hypopetalia pestilens McL. ; no oblique sutures are visible. Text figs. 9d and lie, e, show segm. 8-10 of younger instars of Petaliids from Chili with conditions similar to Aesch- nidae, but no oblique suture is visible in the figures. 4. Of the larvae of Gomphidac, which all seem to live on the bottom, I studied at first a skin of Goniphns piilchclhts without success in discovering any oblique suture, but later, after having compared several other forms, I came to the conclusion that the 130 ENTOMOLOGICAL NEWS [April, '51 tr. scl. in this family seems to be restricted to segm. 7 and 8 only. I found this condition in Ictinus (decoratus and pertinax, fig. 2b), Leptogornphus (Santcri and Lansbergei), Archaeo- gomphus sp. from Nova Teutonia, Brasil, Droinogomplnts spi- nosus, Bunnagoniphns Laidlaivi (det. et ded. Dr. F. C. Fraser), and here the sutures were easily visible in dry material. In a study of a series of exuviae of North American Gomphits, re- ceived from and identified by Dr. E. M. WALKER, after cleaning them or not, I was able to find the tr. scl. on segm. 7 and 8 in G. I'illosipes, brcz'is, qnadricolor, spicatus, furcifer, jraternus, and at last the sutures were discovered also in a somewhat cleaner specimen of G. pulchellus, so that it seems that the prob- lem of the presence or absence of the tr. scl. will become merely a question of sufficient cleaning of the sclerite's surface ; but this is a very dangerous task in such precious skins, where the pin mostly inclines more to penetrate and destroy the skin than to clean its surface. Up to date, I have been unable to find the sutures in Gomphus vulgatissimus and G. flavipcs, Ophiogom- phns scrpentinus and Onychogomphus ford pat us, and I wonder, whether it may be present or not even in Hagcnhis brevistylus. 5. A female exuvia of Cordulcgaster ammlatus was cleaned and mounted in Fauvre's fluid. I was much surprised to dis- cover that the spir. scl. was missing here even in segm. 9, where it is present in all other Anisoptcra studied, and even in Epio- phlebia. Tr. scl. was present in segm. 4-8, always of moderate size, but somewhat contrasting in shape to the condition in the Aeschnidac (fig. 2a), when compared on the segments nearer to the thorax (fig. 2c).

In the skins of Corduliinae studied the spir. scls. were al- ways present on segm. 2-9, but the tr. scl. showed a surprisingly different condition, furnishing a scale more extended than in any other family and perhaps of phyletic importance within the Anisoptera. This will probably become more evident when other important forms such as the nymphs of Petaluridae, and some Australian Corduliinae will have been compared. Very probably, forms with tr. scls. on many (all middle) segments, as in Aeschnidae, will show a more primitive condition than those in which the sclerite is reduced to only a few segments, as especially in Gomphidae and Libellulinae (see below). a). In our material, we consider as most primitive (of all studied Anisoptera) the remarkable condition in Oxygastra Curtisi (fig. Ic), in which the tr. scl. was found on segm. 3-9, that is, on more segments than in any other observed form. These sclerites are very small in segm. 3, 7 and 8, larger in the others, and largest in segm. 9. No spiracle, however, was found on segm. 9, just as in all other Anisoptera. The size and form of tr. scl. of segm. 9 of O.rygastra makes it probable that the sclerite on segm. 9 of other Anisoptera (except Cordulc- gaster again) will be a tr. scl. and not a spir. scl. as previously supposed! b). tr. scl. on segm. 48: Somatochlora arctica; c). on segm. 4-6 and 8: Cordulia aenea, which has a longitudinal oblique hump on spir. scl., bearing the spiracle (fig. 2d) ; other Somatochlora sp. (metallica, flavomaculata, alpestris, cingulata, williamsoni) ; d). tr. scl. on segm. 46 only: Neurocordulia yamaskanensis; e). on 45 only: Tetrageneuria cynosura; f). on 3-6: Procordiilia sp. from Java; g). 3-4 only: Epicordulia regina; h). tr. scl. wholly absent: Macroinia (illinoiensis with a large hump on spir. scl., clio], Didymops transversa (with a lower hump), and Epitheca bimaculata. 7. Similarity in general appearance, along with minor differ- ences, seems to characterize the Libellulinae, but never more than 3 pairs of tr. scl. were discovered. In most cases I found this sclerite on segm. 3-5 ; for instance, in the 3 European Libellula spp., Orthetrum cancellation, Perithemis tenera (NEEDHAM ded. et det.), Crocothemis erythraea (fig. 2e), Syinpetruni mcridio- nale and scoticum, Pachydipla.r longipennis, in 4 European lxii| ENTOMOLOGICAL NEWS 133 Leucorrhinia spp. (not in L. candalis), Tritheniis annnlata. The following exceptions were found: Zygonyx iris (det. Dr. F. C. FRASER, fig. 2f) and Pantala flavescens had the tr. scl. on segm. 3-4, and even Leucorrhinia candalis only on 3. When preparing the skins (cutting off the dorsal cover and of segm. 10 + appendices, putting away the rectal skin and longitudinal stems of tracheae, then cleaning and mounting in Fauvre's fluid), I saw a pair of apodcnics of respectable length on the anterior border of spir. scl., vertical to the body surface, each laterally, on both sides, entering the interior cavity. Such apodemes were found on segm. 6 of Oxygastra Curtisi (fig. Ic) and Cord ul ia aenca (fig. 2d) in both figures marked with punctures, in the Fauvre's fluid preparation it was folded back by the pressure of the coverglass and on segm. 4-6 in Complins pnlchcllns; they were not seen in Cordnlcgaster, Aeschna cy- anca, Ana.r impcrator and Synipctrnni scoticnni. "There is every reason for believing that sclerites have been correlated with muscles in their evolution, if not necessarily in their origin" (SNODGRASS, 1931, p. 5). In consequence of this we may sup- pose, that sclerotization in the lateral region of the larval ab- domen is correlated with the greater number of muscles there than in the imaginal abdomen, and the development of tr. scl. should correspond to this condition also. But, although we are fortunate enough to possess some fine and careful studies on abdominal musculature of Anisoptcra, and although some mus- cles are described attaching on "pleura!" parts, we were unable to find any muscle on tr. scl., neither in WALLENGREN (1914), who discovered the //'. scl. in Aeschna grandis, nor in \YHEDOX (1919), who studied Ana.r jitnius and Tranica Carolina, nor in FORD (1923 ), whose subject was Libcllnla 4-macnlata, so that it is probable that no muscle is attached to tr. scl. Perhaps such a muscle may still persist in forms in which the tr. scl. is of a larger size, as in Cordnlia aenca, but to date we can only sup- pose that in the absence of muscles adhering to the sclerite, the latter has lost its function. Here, as in other known instances, a relatively primary and ancient condition may be preserved longer in a minute functionless organ than in an appendage exposed to influences from the outside (cf.

Esta especie pelo subtriangulo com 3 celulas, ultima antenodal incompleta, carina transversal do 40. segmento abdominal, pelo aspecto do penis e direqao do dente do hamulo, enquadra-se no grupo IV de Borror, formado por Oligoclada heliophila Borror, 1931 e Oligoclada raynei Ris, 1919, de cujo grupo porem, nao participa pela ausencia de projeqoes laterais do occipute; por este caracter e pela forma do penis, verifica-se ser esta especie intermediaria entre o grupo IV e os grupos V e VI de Borror, diferindo, porem, desses grupos, pela posiqao do dente do hamulo, em diregao caudal. Na mesma situaqao dessa nova especie, enquadra-se Oligocladc haywardi Fraser, 1947, pro- veniente de Porto Iguassu, Territorio das Missoes, Argentina. Fraser deixou de mencionar caracteres importantes para a carac- terisagao desta especie, bem como nao figurou o penis, caracter decisive para o reconhecimento dos grupos naturais, nesse genero. Segundo Fraser, 0. hay^vardi e aliada de O. abbreviate (Rambur, 1842) o que porem, nao se pode justificar, segundo demonstra a propria figura 3f dada por Fraser em sen trabalho onde se verifica que o dente do hamulo dirige-se em posiqao caudal. Sendo o penis de 0. abbreviata de forma espetacular dentro do genero, seria curioso conhecer o penis de 0. hay- wardi.

A New Species of Uroxys from Peru (Coleoptera: Scarabaeidae) By MARK ROBINSON, Research Associate, Department of Insects, The Academy of Natural Sciences of Philadelphia Uroxys variabilis new species This species differs from prodiictns Arrow by the lack of a strong sulcus in the middle of the pronotum and the shape of the basal groove of the pygidium. From cupresccns Westwood it is distinguished by the lack of a strong angulation at the inner edge of the male anterior tibia. From both of the above species and all other species in the genus it can be separated by the apices of the male major elytra, which are very different. Thanks are due Dr. A. Martinez of Buenos Aires, Argentina, for confirming the status of this very interesting insect. Male major. Elongate; shining; dark reddish, hairs light brownish. Clypeus triangularly emarginate with a tooth on either side of the emargination. There is a shallow, longitudinal sulcus running back from the clypeal emargination. The eyes are large and are separated by about twice their combined width. The surface of the frons and clypeus is minutely punctured and microscopically alutaceous. The edge of the genae and clypeus are fimbriate. 5 Determined by Professor H. H. Ross. 140 ENTOMOLOGICAL NEWS [April, '51 Side margins of the thorax are widest just back of the middle. Inside each side margin is a shallow, longitudinal sulcus. The pronotal punctures are a trifle larger in diameter than those on the head. The apices of the elytra near the first to fourth striae are produced to the rear into rounded lobes. The striae are well indicated and regularly, crenately punctured. The intervals are barely convex. The surface of the intervals are punctured about the same as the pronotum. The anterior femur is unarmed. The fore tibia is quite long and very thin near the base with the inner edge slightly flexuous. The outer edge is tridentate in the distal one-third. Anterior tibial spur slender, down bent in distal one-third to the acute apex. The suture between the mesosternum and the metaster- num is acutely produced forward. Base of the pygidium has a nearly straight groove running from the middle toward each side. Length, 10.0 mm. ; breadth, 5.9 mm. Male minor. Like the male major with the following excep- tions. The apices of the elytra are rounded and not produced into lobes. The suture between the mesosternum and the meta- sternum is not produced as far forward as it is in the male major. Thorax is widest at the middle. The anterior tibia is shorter and not quite so thin in proportion. Length, 7.3 to 8.5 mm.; breadth, 3.6 to 4.1 mm. Female. Agrees with the male minor with the following ex- ceptions. The thoracic side margins are widest before the mid- dle. The anterior tibia is wider with the inner edge nearly straight while the outer edge is tridentate in the distal half. The anterior tibial spur of this sex is not as strongly curved downwards as it is in the male. Pygidium does not slant for- ward so acutely therefor the abdominal segments are wider along the center.

Frey. \ olume 1 has been published by the Museum as of December 31, 1950, under the editorship of Hans Kulzer and consists of 284 pages with text-figures and four plates. It is planned to publish twice a year with a total of about 600 pages annually. Orders should be placed with: Buchhandlung Dr. E. Reitter, Waltherstrasse 27, Miinchen 15, Germany. This journal is devoted almost exclusively to Coleoptera. In its preface, Georg Frey gives an outline of'his personal history as a coleopterist and tells the story of the growth of his collec- tions and the establishment of the Museum. Beginning as a collector of local insects, Frey's interest gradually increased so that he undertook collecting trips to other parts of Europe and began acquiring more beetles by trade and by purchase. Fi- nally, he became interested in exotic species also and made trips to Africa, South America and the United States. Gradually, too, he attracted interested and capable co-workers so that the work on the collections became so extensive with many species to be described, monographs and keys to be published that it became necessary to undertake this new journal. This first issue contains ten papers, all on Coleoptera except one short paper on CJirysis. The more important ones are by H. Kulzer and by C. Koch on Tenebrionidae (the family best represented at the Museum) and by J. Bechyne (in French) on Chrysomeli- dae and Eumolpidae. All of these include American or Latin American forms. Other papers are by Breuning, Guignot, Koch Stocklein and Schein. Bonner Zoologische Beitrage. Published quarterly by the Zoologisches Forschungsinstitute und Museum Alexander Koenig, in Bonn a. Rhein, Germany, this journal was begun because of a lack of media for the publication of faunistic and systematic works. In keeping with the specialties of the mu- seum, it will publish chiefly on vertebrates and on insects. The first issue contains seven papers (56 pages) on birds and bats and 37 pages on insects. Of the insect papers, those by Mell, Rensch, Buchholz and Klapperich are of interest to workers on American insects and are included under the titles in "Current Entomological Literature" in EXT. NEWS for March. Price : DM 3.50 per issue; DM 14.-- per volume, less 10e <$ and aUotype $ : American River, Sacramento, CALIFORNIA, July 15, 1914 (pair), C. H.

This seems to be the most variable in size of the three sub- species of S. occidentale, and is on the whole the smallest. The series from "California" contains a number of individuals, chiefly females, that are about the same size as average S. sciiiicinctinn. 162 ENTOMOLOGICAL NEWS [May, '51 Measurements of 10 <$<$ and 1 $$ from various localities are as follows : Length J 1 31-37 mm., $ 28.0-33.5 ; abd. (excl. apps.) $ 18.5-23.5, ? 19.5-22.5; hind wing ^22.5-28.0, $22-26. Intergradation with 5". o. occidentale is found in White Pine, Eureka and Nye counties, Nevada. In the series from White Pine Co., 9 <$<$ and 15 5$, the females could all be placed almost equally well with occidentale. The pale thoracic pleura, which turn grayish in old individuals, are like those of cdlifornicum, while the yellow area of the hind wings ($$ ) is smaller than in typical occidentale but not so diffuse as in typical califoniicitin. The males could be placed almost equally well in either sub- species but the yellow (or brown) area of the wings is never distinctly deepened distally as it is in fully mature occidentale. Intergradation of the two subspecies in the coastal zone, i.e., between Oregon and California, has not been observed in the limited material from that region. Sympetrum occidentale fasciatum subsp. n. This subspecies in its typical form is easily recognized by its wing pattern. The colored area reaches the nodus in the front wings and one or two cells beyond it in the hind wings, and in both pairs the proximal part of this area is pale, or, in old individuals, relatively pale, while the distal part is dark yellow or brown, forming a band of nearly uniform width, crossing both wings from front to hind margin and terminating abruptly in an almost straight line. The pale yellow parts of the thorax and abdomen turn greenish gray in old individuals. The black mark- ings of the thorax tend to be less heavy than in the other sub- species. While fasciatum is, on the whole, somewhat less stocky in build than the other forms, with the abdomen relatively a little longer (text-fig. 2), this difference is not constant enough to be useful as a taxonomic character. The range in size is similar to that of 5". o. californicinn. Measurements of 10 ^ and 10 $5 are as follows : length J 1 30- 37 mm., $ 30-34.5 ; abd. J 1 18-23, $ 20-23 ; hind wing J 1 ? 23-27.

This subspecies thus inhabits the arid and semi-arid plains east of the Rocky Mountains, from southern Alberta to New Mexico, also reaching eastern Utah and northeastern Arizona. Records of 5". seinieinctiun from Oklahoma and Texas probably belong to this form. The only specimens we have seen that give indications of intergrading with other subspecies are those from Rio Grande Co., in southwestern Colorado, viz. 2 <$<$ and 4 $$ from the San Luis Valley, Monte Vista. These are like fasciatitin in the clearly defined yellow areas of the wings and in the relatively large size of this area on the front wings, but they differ from typical faseiat 11111 in having only slight traces of the dark distal wing bands.

FRANCIS BYERS l The scarcity of local lists of Virginia Odonata as well as the prominent role being played by the Mountain Lake Biological Station of the University of Virginia in the study of the natural history of the Southeast, makes it desirable to record known information of the fauna and flora of the area in which it is located. The Mountain Lake Biological Station is situated in Giles County, in western Virginia, at an elevation of nearly 4,000 feet. The writer was in residence at the Station from July 23 to August 26, 1949, during which time an attempt was made to study the dragonfly fauna of the region. The following account is the result of this study. Dragonflies are not common in the Mountain Lake area. Neither a large number of species nor a large number of indi- viduals were found. Except for the Argia, Ischnura, and Enal- lagnia of the less wooded portions of the lake shore and the Epicordnlia flying over its waters, one seldom saw more than one dragonfly at a time. Collections made at lower elevations, at the ponds and rivers around Blacksburg and Pembroke, showed a somewhat greater variety of dragonflies.

On another day an Aeschna was seen flying along a narrow, heavily wooded trail leading to Rattle Snake Rock. Neither of these specimens were captured. Cordulegaster diastatops (Selys). 3 large and 2 small nymphs were collected by Chester Mann on August 1 1 at White Pine Lodge, along with specimens of Lanthus albistylus, in clear water pools. A small nymph was taken from a sphagnum bog at the head of Little Stony Creek on July 27. An adult female of this genus was observed laying eggs in the Station swimming pool on August 1. 166 ENTOMOLOGICAL NEWS [May, '51 Epicordulia princeps (Hagen). 1 J 1 , 1 $, Aug. 11.

Review Pierre Viette. Lepidopteres Rhopaloceres de 1'Oceanie Fran- <;aise ; Faune de 1'Empire Francais, XIII. 1950. This is the very highest type of what might be called the stamp collector's approach to the butterflies. It is well organ- ized, perfectly clearly presented, with keys, good figures, includ- ing genitalia when useful, and all the data necessary to determine the butterflies from the French islands of the southwest Pacific but hardly anything more. The prospective field collector will miss data on caterpillars, foods, life cycle and ecology ; the zoogeographer will have to make his own tabulations, based on other works ; for the distributions cited are practically limited to material from the French islands, and outside localities are not quite trustworthy. There is also no synonymy, and one will be occasionally puzzled to find the species in other works. A rough count shows 42 species actually reported from New Caledonia and 43 from the New Hebrides, with a few more known from both the Loyalties and the New Hebrides, which ought to occur in New Caledonia. There are ten from Tahiti, five from the Marquesas and only scattering records of. wide- IxiiJ ENTOMOLOGICAL NEWS 179 spread species from the remaining islands. The endemics are about as one might expect : a few from New Caledonia, includ- ing the endemic genus Paratisiphone, none that I notice from the New Hebrides, though there are some striking subspecies of wide-spread species ; two from the Marquesas and somewhat surprisingly an endemic genus of Blues from Tahiti (Hypo- jamides). It is notable that all save those from New Caledonia are represented by very few specimens the Tahiti species by two specimens taken a century apart, the two Marquesans by a unique and three females. It looks as though a few may yet be found, but more probably several are gone forever before discovery. Type localities are cited without question, and it should be noted that "Coromandel" is often one of the notorious early false localities. Delias ellipsis is cited without question from "Aus- tralia," but Talbot notes that the types are labelled "Antipole," a place which does not exist in Australia; perhaps there is or once was a village of that name in the New Caledonia group. In any case the newly discovered specimen from New Caledonia is the first trustworthy record of the species from anywhere, and of this wide-spread genus from New Caledonia. "Danaus plexippus" is noted without synonymy, and only a close reading shows that the American Monarch is meant rather than the Asiatic species which Linnaeus confused with it, and which has fought for the name ever since. To add to the con- fusion it is given as subgenus Danaus, which is correct for the Asiatic, but not so good for the American species (Diogas d' Almeida). Libythea is put in the Nymphalinae, following Zerny and Beier, without noting that while the palpi are not too important, the genus also has Erycinid and not Nymphalid legs, and an unique larva. Surely it deserves at least a subfamily (or a "splitter's" family). WM. T. M. FORBES. The Wasmann Journal of Biology. This is a new name for the well known and now enlarged "Wasmann Collector."

THE LANCASTER PRESS, INC., Lancaster, Pa. ENTOMOLOGICAL NEWS VOL. LXII JUNE, 1951 No. 6 Some New Dragonfly Records for Kentucky (Odonata) By CARL COOK, Crailhope, Kentucky In 1924 Carman l published the only more or less compre- hensive list of Kentucky dragonflies that has appeared to date. Based on collections made by himself, together with numerous previously published records, he was able to bring together a total of 65 - species for his list. Since that time the dragonflies have been almost completely neglected in Kentucky, less than a dozen additional species have been recorded for the state since Carman's paper. Because of this almost total lack of information concerning the distribution of this group of insects in Kentucky, the writer has undertaken to prepare a complete catalogue of the Odonata known to occur within the state. However, since a great deal more collecting needs to be done, most especially in the western and far eastern parts of the state, before our knowledge of the distribution of the various species in the different counties is sufficient to allow the completion of my state list. And since this field work is expected to take at least two more summers to complete, I be- lieve there is justification for offering this short list of new records in the meantime so that these records may be available for use by other students of the Odonata as soon as possible. 1 CARMAN, H. 1924. Odonata from Kentucky. Entoin. AYcv'.v 35: 285-288. 2 CARMAN actually lists 66 species but according to Ris (A revision of the Libelluline Genus Perithemis. Misccll. Pub. Mus. Zool. Unir. Midi. No. 21, p. 17. 1930.) all records of Perithemis doniitia from the United States belong to tcncra. (181) 182 ENTOMOLOGICAL NEWS [June, '51 During the ten years I have been collecting dragonflies in Kentucky, I have taken a total of 94 different species of which 35 have not been reported from Kentucky previously. Two others are being recorded because their capture represents ex- tensions of the known seasonal range for these species. This list is based upon a collection of 1182 specimens made from the following twenty counties : Adair, Allen, Barren, Casey, Chris- tian, Edmonson, Fayette, Floyd, Green, Hardin, Hart, Letcher, Marion, Metcalfe, Pulaski, Rockcastle, Taylor, Wayne, Wash- ington, and Whitley. It will be instantly apparent to the reader that little more than "scratching the surface" has yet been done in collecting dragonflies in Kentucky ; we have collections from less than a quarter of the state's 120 counties and nowhere, with the possible exception of the writer's immediate neighborhood, have dragonflies been collected at all extensively in the state. Even in counties where collections have been made, it must not be assumed that they were made with equal completeness, for instance, Pulaski County is undoubtedly capable of yielding as many species as Green County yet because we passed through Pulaski with only one five minute stop we were able to collect but one species, while from Green County \vhere we have col- lected more or less intensely over the past ten years, we have taken 81 species. It is hoped that resident collectors and persons passing through, or collecting in, Kentucky will make an effort to secure specimens of dragonflies at every opportunity. The writer would welcome the opportunity to examine all such collections for possible extensions of geographic or seasonal range and proper credit will be given for any usable records. Representative specimens of all species listed herein are in my own personal collection, a few have been sent to Dr. Philip P. Calvert for the collection of The Academy of Natural Sciences of Philadelphia, and still others have been given to various other students of this group of insects. The writer is responsible for all specific determinations, with the exception of the two species noted below. I wish to acknowledge the assistance of my mother, Mrs. Elizabeth Cook, in collecting many of the specimens, and in Ixii] ENTOMOLOGICAL NEWS 183 other matters. I am especially indebted to Dr. Philip P. Calvert for determining Ophiogoin pints aspersus and Neurocordulia yamaskanensis, and to Dr. Minter J. Westfall, Jr., who very kindly checked representatives of many of the Anisoptera and has been of much assistance in other ways. LIST OF SPECIES Hetaerina titia tricolor (Burmeister) . Green Co.

The author did not at- tempt to include fossil roaches with the living ones, but it is evident that the venation of many fossil forms has much in common with that of the primitive family Polyphagidae, and the ground is now prepared for the integration of fossil and Recent systems. It may be noted that the small basal anal fan of the primitive Australian termite Mastotennes is likewise much like that of certain Polyphagidae, supporting the current view that termites and roaches have a common ancestry, or that termites are a specialized offshoot from primitive roaches. In many previous systems, Polyphaga and its allies were not recognized as the basic primitive group of existing roaches. In 1948, when the main portion of the present investigation had been completed, but of course not published, C. F. A. Bruijning of Leiden incorporated in a large paper on Malayan roaches his views on evolutionary trends in wing development. The primitive character of the Polyphagidae, the significance of different ways of folding, and the specialized nature of the ap- pendiculate field of certain higher forms were fully recognized by him. In effect, therefore, these two workers on opposite sides of the Atlantic Ocean independently reached a comparable conclusion regarding many natural relationships. Personally, I feel that fuller comments on Bruijning's observations would have been helpful in the introduction of Rehn's classification. The Blattaria are treated as "a series, or as a superfamily, in the suborder Dictyoptera," and 5 families are recognized, with 17 subfamilies and 43 tribes. The classification is natural, new, and progressive, with ample opportunity for spread and balance in arranging categories based on characters of differing funda- mental importance. Yet, the identity of the order Orthoptera is preserved, and a student is not confused by a maze of families such as sometimes appear in new classifications. In 1932 Brues and Melander placed the Orthoptera in 5 orders, and recognized 24 families of roaches. When we realize that the serious sys- tematic study of Orthoptera is relatively recent, and that much fundamental knowledge has been assembled in this century by Ander, Carpentier, Chopard, Crampton, Ford, Judd, Karny, Roberts, Slifer, Snodgrass, Walker, Zeuner and others who have made comparative studies, it logically follows that we should adopt a new, more realistic arrangement of the suborders and superfamilies. The new roach classification is commendable for IxiiJ ENTOMOLOGICAL NEWS 205 its progressive features, yet at the same time it is pleasantly con- servative in a broad sense. Taxonomists will find useful the identification keys to families and subfamilies, which are based wholly on wings. Only two subfamilies have numerous tribes, the Epilamprinae with 12, and the Pseudomopinae with 1 1 . The genera and species illustrated are indexed, but a few other genera which are discussed, such as Phlebonotus and Notolampra (p. 79), are omitted. For al- most every specimen illustrated, the name of the entomologist making the identification and the date when it was made, also the place where the specimen was collected, are carefully documented. The author states that names used for tribal and other categories have been chosen because they are unambiguous and representa- tive. Some workers will feel that the tribal name Corydini, which Rehn has used, should be abandoned because Princis 1 has just pointed out that Corydia Serville 1831 is a synonym of Therea Billberg 1820, each having the same type species. In the absence of definite rules regarding the names of supergeneric categories, however, it appears permissible and even desirable to retain those based on synonymous genera if such usage otherwise makes for stability and uniformity. To change a well known family or tribal name whenever a type genus falls in synonymy could easily keep higher categories in a continual state of confusion. In addition to the different basic approach and resulting re- arrangement of the systematic structure, several matters of relationship shown by the new classification are especially note- worthy. Distinct families are based on Diploptera and Oulop- tery.r. The striking wing venation of the former is well known, but Ouloptcryx is an obscure genus described by Hebard in 1921 with two species occurring in French Guiana and Brazil. The family has several quite basic features, including the spiral roll- ing of the appendiculate field when the wing is closed. Hor- iiictica and Brachycola are placed in a new subfamily, the Brachycolinae. Rehn finds that the former subfamily Pan- chlorinae cannot be maintained separate from the Epilamprinae, and the Panchlorini now appear as a tribe of the latter subfamily. Taxonomists have long debated the distinctness of the Ectobiinae and Chorisoneurinae ; the latter are now reduced to tribal status 1 K. PRIXCIS, 1950, Opuscula Ent. 15: p. 162. Unpublished notes of A. N. Caudell show that he realized this synonymy a good many years ago. Though long considered of questionable nomenclatorial validity, the Billberg genera, where based on described species, are now generally accepted. 206 ENTOMOLOGICAL NEWS [June, '51 within the Ectobiinae. Calolampra, usually considered a close relative of Epilampra, is made the basis of the tribe Calolamprini and arranged in a different line of development from the Epi- lamprini (see diagram of probable relationship of components of the Epilamprinae, p. 63). It is not clear to me why Calolanipra is thus placed nearer Oniscosoma and Blaptica, of the Oniscosomini, than to Epilampra. One naturally wonders what modifications of the new clas- sification will be found necessary as further studies are made. The 68 genera which were critically studied and illustrated have been grouped in 43 tribes, an average of less than 2 genera per tribe, not counting additional genera that were surveyed. Clearly, the choices made have been excellent, but with such a ratio the possibilities for corrections becoming necessary are considerable. At least 16 tribes are now each considered to include a single genus. The subfamily Euthyrrhaphinae is treated as including only one genus, Enthyrrhapha. I have found, however, that Zetha Shelford 1913 also belongs in the subfamily. Zetha is a little known genus originally described from Ecuador from a short-winged female ; fully winged males have since been discovered and several species are recognized, one of which has been taken in Central America and the Azores. Tegmina of Zetha show the venation more clearly than do those of Enthyrrhapha, and the wings have a smaller number of veins, so that some modification of the subfamily diagnosis will be necessary. - Concerning the Oulopterygidae, the author states that Mcl- yroidea probably is a member of the family ; evidently no spec- imens were seen. The National Museum has a specimen of Melyroidea magnified Shelford, collected at Chanchamayo, Peru, in 1948, and the suggested family placement is confirmed. Shel- ford proposed Melyroidea in 1912 for two then new species, miuieticd with short cerci and believed to be from near Rio de Janeiro, and magnified with very long cerci from Ecuador. I suspect that the two species are non-congeneric, and possibly mimeticd really belongs to Oulopteryx, so in order to prevent further confusion Melyroidea magnified Shelford is here des- ignated type of Melyroidea. The tegminal area between radius and media of M. magnified is entirely veined, and the diamond- shaped area lacking veins described for Oulopteryx is not con- sistent for the family. The cerci are basically much more elongate and of different shape than those of Oulopteryx, so that distinct genera are clearly represented and perhaps separation " For some time I have had a study of the genus Zetha in progress. Ixii] ENTOMOLOGICAL NEWS 207 on an even higher level within the family will eventually be desirable. Specimens of two apparently distinctive groups, the Xocti- colinae and Archiblattinae, were not available to John Rehn for study, and published information was insufficient to place them definitely. In my opinion, certain of the various wingless genera may also require special provisions in the classification when fuller studies are made. For instance, the wingless Cryptocercus, which is an unusual component of the Nearctic fauna and also includes Asiatic species, has been grouped traditionally with Panestliia, but Cleveland 3 has reported Cryptocercus to be quite different both externally and internally. It is perhaps natural that an entomologist interested in iden- tification problems should continually look for too much of what we ordinarily expect of monograph in this analytical outline of higher categories. However, as a result of difficulty in plac- ing certain genera, which Rehn did not discuss, in the ap- propriate tribes, I cannot help but feel that a logical and ex- tremely valuable appendix would have been a check list assigning the known genera in their proper place in the system, insofar as possible at this time. It would be interesting, and probably decidedly helpful, to correlate the biology of roaches with the classification. I have considered, in a very preliminary fashion, the genera known to be viviparous, as opposed to those depositing well formed oothecae. So far as I have learned, all roaches of the Pseu- domopinae and those grouped in advance of that subfamily in Rehn's linear arrangement deposit oothecae of the usual sort. The typical Panesthiidae, the Diplopteridae, and apparently the majority of the remaining Blattidae, except Blattinae and Xycti- borinae, are viviparous. Cryptocercus, unlike Panestliia, has a peculiar ootheca, and the Polyphagidae, so far as their breeding habits are known to me, have highly distinctive oothecae. This brief outline of breeding habits is given to further suggest the natural and logical character of most of the new system, and to indicate the possible value of studies along this line. The new classification of the Blattaria marks a highly signif- icant step forward and as such adds dignity to our taxonomic science. We may hope that its author will be among the fore- most to continually test the links of this chain he has forged, and to add new or stronger links where gaps are found. ASHLEY B.

THE LANCASTER PRESS, INC., Lancaster, Pa. 261951 ENTOMOLOGICAL NEWS VOL. LXII JULY, 1951 No. 7 New Records of Maine Dragonflies (Odonata) By DONALD J. BORROR, Department of Zoology and Entomology, Ohio State University, Columbus 10, Ohio Since the appearance of the latest list of the Odonata of Maine (Borror, 1944), four additional summers of collecting by the writer in south-central Maine have yielded a number of new records of Odonata. Many of these represent new locality or new county records, and the records of four species represent new state records. These four species bring the total number of species of Odonata for Maine to 1 19. There has been considerable dragonfly collecting in some sec- tions of Maine, but other sections remain relatively unexplored, at least as far as the dragonfly fauna is concerned. The table below, which includes the records in this paper, represents fairly well the thoroughness of dragonfly collecting in different parts of Maine. TABLE I.

The four species new to Maine are Coenagrion inter- rogation (No. 116), Erythrodiplax Berenice (No. 117), Libcl- (209) 210 ENTOMOLOGICAL NEWS lula (Holotania) cyanea (No. 118), and Erythemis simplicicollis (No. 119). The locality records, which are records not pre- viously published, are listed by counties (COUNTY names are in CAPITALS). Locality names are taken from the topographic maps of the U. S. Geological Survey. Detailed data are given only for the new county records ; in the case of records from new localities in counties from which a species has previously been reported, only the localities are listed. The records from counties marked with an asterisk (*) are new county records. All material listed, together with that indicated by locality names only, is in the writer's collection. The dates following the new records of each species are the extreme dates for collections of adults, based on eight seasons of records (June 9 through August 29) by the writer in south-central Maine. 1.

The original descriptions are in order and the holotypes are properly labelled to agree with them. Specimens of altissima, labelled remigis were sent out to sev- eral of my friends and no serious trouble would have resulted except that Dr. Hull (Trans. Zool. Soc. London, Vol. 26: p. 293, 1949) erected a new subgenus, Metepistrophe, for remigis FL, but it was evidently based on the specimens so labelled, which were actually altissima Fl. The paper on genitalia carried this new subgenus and added argentipila Fl. to it, but here again it was done on mislabelled specimens of remigis. My interpretation places remigis (cor- rectly labelled) under the genus Episyrphns and places altissima under Metepistrophe.

SIMKOVER, University of Wisconsin, Madison, Wisconsin Certain observations made during a four-year study of June beetles at Wisconsin forest tree nurseries regarding feeding habits, flight habits and "broods" of June beetles are believed worthy of recording. A. FEEDING HABITS In general, June beetles are not supposed to feed on conifers, but European larch at Griffith State Nursery, in central Wis- consin, was so heavily utilized in 1949 that the branches were nearly stripped for a distance of about 12 inches from the tip. Table 1 lists the species and the percentages collected from larch. Of all June beetles collected from vegetation at the nur- sery in 1949, 14.20% were taken from this host. In contrast, in 1947 no specimens were found on larch, only one in 1948, and very few in 1950. TABLE 1.

Approved for publication by the Director of the Wisconsin Agri- cultural Experiment Station. 220 ENTOMOLOGICAL NEWS There appears to be a particular physiological condition of the host which proves attractive to the beetles since they are drawn in large numbers to specific plants in a given year while other plants of the same species are avoided. For example, tristis in 1948 was attracted to one bur oak in large numbers (823 having been taken one night) while another bur oak of about the same size and apparently in the same condition attracted almost no beetles although it stood within 20 feet of the first. The tree which attracted large numbers in 1948 was fed upon by only a few beetles in 1950, although tristis was very numerous on other trees. Furthermore, the attractiveness varies during the feeding season, i.e., some, but not all, trees lose the ability to draw the beetles. B. FLIGHT HABITS (1). Height of flight. During a 28 day period in 1947 five light traps at the Griffith Nursery, placed at a height of about five feet, averaged 41.48 June beetles captured per night per trap. Meanwhile, a trap located on a fire tower at the nursery at 17 feet averaged 55.74 or 1.35 times the number taken in those at five feet. Another trap located on the tower at 44 feet averaged 3.70 beetles or only 6.6% of that at 17 feet. One located at 72 feet, which was operated for fifteen nights, caught 62.2% as many beetles as the one at 44 feet during the same nights. A trap at 92 feet took no beetles during four nights although the trap at 17 feet averaged 174 beetles for these nights. However, the towerman stated that it was not unusual to find June beetles in his room at the top of the tower, approximately 102 feet, if the windows were left open at night. There were no obvious differences in the proportions of the sexes which were captured at the different heights. A total of over 6,000 marked males, of several species, was liberated at various times just before dusk. The majority rose to an estimated height of 30-35 feet before leveling off. From these observations, and from watching the insects come to the trees in the evening, the writers believe that the average height of flight of June beetles is higher than the literature would lead one to believe. Ixii] ENTOMOLOGICAL NEWS 221 (2). Xoctitrnal activity. June beetles are supposed to emerge from the soil or litter within a relatively short period in the evening and literally swarm to the host plants where mating and feeding commence at once. Supposedly they remain rather quiescent until near dawn when they move back to the ground. However, tristis is the only species at the nurseries that has been observed to swarm in this manner. Apparently some unknown stimulus is responsible for the rhythmic nocturnal activity and diurnal quiescence. Beetles in the laboratory become active in the evening even when a strong light is shown on the cage continuously and although the tem- perature remains unchanged. When brought into the laboratory from cold storage and warmed up they show the same sort of rhythm regardless of the time of year. A light trap which segregates insects caught during hourly intervals has been operated for the past four years. Collections made in this trap indicate that the time of maximum attractive- ness of the traps is from approximately 9 :30 P.M. to 1 :30 A.M. From the evidence obtained, it appears that the beetles fly to the host plants and settle down about dusk or later, feed for a time, and then fly and feed sporadically throughout the remainder of the night. In general, the proportion of females to males cap- tured becomes smaller as the night progresses, reaching the lowest point at about 1 :30 A.M. and then increasing somewhat up to 4:30 A.M. C. "BROODS" The authors question the validity of the use of the terms "Brood A," "Brood B," and "Brood C" in th
