Lancaster, Pa. ENTOMOLOGICAL NEWS VOL. LX FANUARY, 1949 No. 1 Xiphocentronidae, a New Family of Trichoptera By HERBERT H. Ross, Illinois State Natural History Suru \ . Urbana, Illinois In collections made by Mr. Harry lloogstraal during his 1940 expedition to Mexico are a few specimens of a most unusual small black caddisfly. This species combines characters which were formerly considered distinctive for three families, the Rhyacophilidae. Philopotamidae, and Psychomyiidae — such a mixture of characters that at first I was unable to place the spe- cies at all. Finally it was tracked to Brauer's long lost genu- Xiphoccntron and it now appears necessary to erect a new family for its reception. During the course of preparation of this paper, a second species of the genus from southern China was sent to me by Dr. E. S. Ross. Xiphocentronidae new family Characteristics. — Size moderate, bod,y fairly slender. Ann i nae reaching to about end of abdomen. Maxillary palps of both sexes 5-segmented, fig. 6, the two basal segments short, tin- third subequal to the first two together, the fourth one and a half times the third, the fifth long, whiplike and multi-segmented, as long as the third and fourth combined.

Of the three species considered as belonging to this genus, I have seen specimens of only the two new ones. To my knowl- edge, the genotype is known only by Brauer 's illustrations. These show characters of venation, tibial spurs, and shape of male genitalia so in agreement with these structures in the other two species that there seems no doubt of the relationship and association. It is interesting that the members of this small, primitive family are widely separated geographically, two from Mexico and one from China. This could indicate a separation of con- siderable geologic time. As a matter of fact, the Chinese spe- cies shows considerable difference from the Mexican in wing venation and male tibial spurs, and the two groups may ulti- mately be considered as generically distinct. The two show such close affinity in genitalia, however, that I prefer to follow a broader generic concept until more information about the fauna indicates the desirability of a change in status.

The Present Status of the Distribution of Vespa crabro var. germana Christ in North America 1 By Prof. M. W. WING, Department of Zoology and Entomology, North Carolina State College. Raleigh, North Carolina Vespa crabro var. ycnnana Christ, the common hornet of Europe, was introduced into North America in the middle of the nineteenth century. H. de Saussure (Ent. News 9: 145, 1898) reported that it was captured in 1854 in the eastern United States. J. Bequaert (Ent. Amer.. N.S., 12 (2): 86, 1931) reported that T. Angus, in 1871, stated that this hornet had been common in the vicinity of West Farms, New York, for the past 25 years. It seems probable that southeastern New York State is the focal point from which this powerful wasp ha> 1 I wish here to express my thanks to Dr. J. C. Bequaert for his kind- ness in sending me several records and for critically reading the manuscript and suggesting several improvements. 8 ENTOMOLOGICAL NEWS [Jan., '49 spread out over a number of the eastern states. In 1931 (J. Bequaert, 1931, loc. cit.) this hornet was well established in Long Island, S.taten Island, southern New York State, northern New Jersey, and southwestern Connecticut. In addition to this area where the wasp was known to he naturalized, specimens had been taken near Philadelphia, in Maryland, and in Delaware. Dr. Bequaert in this paper also called attention to and discussed several published records, which he considered to be open to question. These records are from the following localities : Illi- nois, North and South Carolina, and New Orleans. In 1935. J. Bequaert (Bull. Brooklyn Ent. Soc. 30 (3) : 120) reported the spread of this species to southeastern Pennsylvania. In addition to this new area of establishment, a J1 taken at Nor- folk. Virginia, was reported. In 1941, J. Bequaert (Bull. Brooklyn Ent. Soc. 36 (3) : 111) reported the spread of this species to most of New York State, eastern Pennsylvania, Delaware, Maryland and the eastern part of West Virginia. Over and above these additions to the area of establishment, trustworthy records of this wasp from Quebec and North Dakota were given. There was, however, no reason to believe that the last two records indicated anything more than accidental importations. This species was taken in North Carolina in 1940 (C. S. Brimley, "Supplement to Insects of North Carolina," 1942). Since that time five additional captures have been made in the state. These additional records, based on specimens which I have examined, are : Guilford Co., Sept. 22, 1944, J. A. Harris, 1 J and 3 ??. Greensboro (Guilford Co.), Early Oct., 1946, D. J. Branie, 1 5 and a portion of the nest. Reidsville (Rock- ingham Co.), Sept. 4, 1947, J. E. Foil, 1 §. Carthage (Moore Co.), Sept 11, 1947, E. H. Garrison, 1 $. Mocksville (Davie Co.), Sept. 15, 1947, J. P. Bowles, 2 $$. The note accompany- ing these specimens reads "working in hollow tree — busy as a colony of bees." In considering the 1940 North Carolina Record, a single $ taken near the railroad tracks on the State College campus, there appeared to be no reason to believe that this species had Ix, '49] ENTOMOLOGICAL NEWS 9 become established in the state, for this individual might well have been brought into this area in a box car from a consider- able distance. But when the other five records, two of which are definitely correlated with a nest, are considered, it seems evi- dent that this powerful wasp is now in the process of becom- ing established in the central portions of this state. In the light of the North Carolina records, and on the as- sumption that the presence of this species here was the result of a gradual extension of its range southward. I inferred that this wasp was undoubtedly well established in Virginia. I then wrote Dr. Bequaert requesting any additional records of this species which he might have. He very kindly supplied me with the following records : Fredericksburg. Va. : Dr. Karl V. Krom- bein found this species nesting here in a hollow locust tree. Limeton, Va. : Dr. Bequaert pointed out the paper of Dr. A. H. Clark (Proc. Biol. Soc. Wash. 52: 179. 1939) which I had over- looked ; it reported V . crabro from the above-mentioned locality. Summit Co., Ohio: 1 J1 taken in June 1934 by L. J. Lipovsky. Dr. Bequaert stated in his letter of July 12, 1948. that Virginia and probably Ohio could now be considered a part of the settled range. He further stated that Quebec, North Dakota. Illinois, South Carolina and New Orleans were still considered by him as doubtful or accidental records. The present established range of \'csf>a crabro covers the fol- lowing states (all of the state or a part of it) : New York. New Jersey, Connecticut. Pennsylvania, Delaware. Maryland. West Virginia, Virginia, Ohio and North Carolina. In my opinion, it would seem highly probable that the wu>p may be found also in eastern Kentucky, western Massachusetts, and southwestern Vermont. In addition to these probable areas of occurrence, it might extend in the not-distant future to north- ern South Carolina, eastern Tennessee, southwestern New Hampshire and possibly Rhode Island. The European hornet typically builds large nests in hollow trees, although other sheltered situations are often utilized, for example, under porches and, in fact, under overhanging roofs of all types. Exceptionally underground cavities are utilized 10 ENTOMOLOGICAL NEWS I Jan., '49 as a nesting site. In Europe attics and barns are favorite nest- ing locations. The degree of completeness of the envelope en- closing the nest varies with the situation. In the more exposed aerial nests, this outer nest covering is usually complete ; in cavities, nests either completely or partially lack this outer cov- ering envelope. The paper of which the nest is made is very coarse and brittle ; its color is a brownish gray. The longer diagonals of the hexagonal brood cells of a nest in my possession measure about 1 cm. Most of these cells have plugs of dark chocolate brown material in their upper, closed ends. These characteristics make it possible to identify accurately the species in this country from the nest alone. It is hoped that entomologists in the areas outlying the pres- ent distribution of this powerful wasp will be on the watch for it, as only collecting on these constantly moving boundaries will give us an accurate timing of the spread of this hornet. The prediction of J. Bequaert (1941, /or. cit. ) that "no doubt this powerful insect will eventually spread over most of eastern North America" will in all probability be fulfilled, since the range of this species is being constantly extended. The Function of the Spur on the Femur of the Palpus of the Male, Leiobunum calcar (Wood) ( Arachnida : Phalangida) By SHERMAN C. BISHOP, Department of Biology, University of Rochester, Rochester, N. Y. During July and August 1948, I was fortunate i-n being able to study at the Edmund Niles Huyck Preserve at Rensselaer- ville. New York, and, taking advantage of an abundance of ma- terials, spent most of the time in observing and collecting phalangids. Leiobunum calcar (Wood) is a common and widely distrib- uted species, the males of which are easily recognized because of the presence, on the femur of the palpus, of a large, ventro- lateral spur. The male palpus is much stouter than that of the female, especially the femur, patella and tibia. The patella is Ix. '49 ENTOMOLOGICAL NEWS 11 short, strongly arched above and curved ventrally, the tibia is produced ventrally at the base and curved ventrally on the distal half. The swollen base is armed with short, dark denticles. Because of the shortness of the patella, the spur on the femur may be apposed to the swollen base of the tibia to form an efficient grasping organ. FIG. 1. Lciobutnnn calcar, male (left) and female in mating position. a. Right palpus of male. Pairs of L. calcar may often be seen to mate in the field and when confined continue the practice at frequent intervals. Un- der the binocular microscope the function of the spur is at once evident. \Yhen the male encounters a receptive female, he rushes at her without preliminary courtship and grasps her firmly. The trochanters of the first legs of the female are held between the spurs of the femora and the swollen bases of the tibiae of the male, the curved ventral sides of the patellae of tin- male fitting the mesal sides of the trochanters of the female. The curved, disto-ventral surfaces of the tibiae of the male fit the mesal sides of the trochanters of the second legs of the female and the tarsi of the male are pressed against the coxae of the second legs of the female. The drawings were made by Carolyn Fallen. 12 ENTOMOLOGICAL NEWS I Jan., '49 On Some Centipeds from Northern Alaska By RALPH V. CHAMBERLIN The centipeds reported upon in this paper were taken by Dr. Neal A. Weber in August of 1948. One species, Oabius sp., was taken at Whitehorse. Yukon Territory, Canada, and three others from Northern Alaska on the north front of the Brooks range, which, as Dr. Weber notes, "must be a formidable bar- rier to life coming from the south." The latitude 68°20' is near the most northerly limit known for chilopods. Previously reported from localities near or north of the Arc- tic Circle were the following from the vicinity of the Yenesei River in Siberia, recorded by Stuxberg in 1876. 1 Litlwbitts nordenskioldi Stuxberg (71°40') Lithobius vagabundus Stuxberg (66° 17') Sonib'ms ostiacorum (Stuxberg) (69° 15') Nampabius sulcipcs (Stuxberg) (66°17') From farther east in Siberia at Pitlekay (67°4' 49" N. and 173°23' 2" W.) on the north shore of the Chukutski peninsula, collectors on the Vega expedition of 1878-79 secured the follow- ing two forms.2 Monotarsobius crassipes Iwlstii Pocock Monotarsobins tricalcaratns Attems Taken at Nanamo, which is also on the Chukutski Peninsula, was : Arctogeophilus glacial is Attems Family LITHOBIIDAE Genus ESCIMOBIUS new Allied to Oabius in having the median and anterior legs with tarsus uniarticulate.

TINKHAM, Box 123, Indio, California j We present here, with the author's permission, some field obser- vations of an interesting dragonfly from the canyons of south- eastern Arizona; also an account of a successful shipment of two of its nymphs for a long distance without water. These are extracts from three letters written by Dr. Tinkham to Dr. James G. Needham of Cornell University, to whom the living nymphs were sent. The first letter was written in reply to in- quiries concerning Oplonaeschna. I'enson. Arizona, October 16th, 1V47. On June 14th, 1940, I found two larvae (naiads) of Oplo- naeschna armata clinging to the under side of a water-logged piece of bark. These were the only ones found. The canyon pools are at the upper edge of what I call the Live Oak Zone of the Upper Sonoran. These pools are formed below big rock boulders and are usually lined with fallen leaves. Some pool- are several feet deep and are fed with running water. After finding the naiads I still had to find a way to transport them safely across the hot desert to Tucson. Years previously in the Big Bend Region of Trans-Pecos Texas I had learned 16 ENTOMOLOGICAL NEWS [Jan., '49 that water in jars soon heats up and kills the specimens. By 1940 I had conceived a new idea (which may have been used before) : I carried them from the Canyon to my car in a wet hankerchief, and transferred them to a waterbag with cool water. They were still in cool water when I reached Tucson the follow- ing night. I put a one or two short twigs about 5-6 inches long in the bag to brace the side walls apart, and some days later my two naiads transformed perfectly to adults. I have used this method to transport frogs and fish on the desert, with equal success. Tucson, Arizona, July 22nd, 1948. Two days ago I got off for the Huachucas, fortunately, just on the eve of our rainy season. You will be pleased to learn that I have obtained six or seven naiads of Oplonaeschna from the upper end of Ramsay Canyon. I used a Chinese wire rake for raking the leaves out of the small pools. On the whole, Oplo- naeschnas were very rare. With the exception of finding one larva under a big flat rock at the mouth of a pool, all were taken in small pools that were almost dried up. In one almost dry pool two naiads were clinging to a rock at the mouth end, not near any water. There was a basinful of water in the deep part of the pool but no Oplonaeschna naiads were there ; there were many Cordulegasters J there. In another completely dried up pool I found three Oplonaeschnas in a mass of leaves at the mouth of the pool where leaves had collected. I believe that these naiads can remain in such places and undergo desiccation for some time. The naiads play opossum by curling up. I took two photos of this pose. I am air-mailing to you a pint cardboard carton with two live naiads in it, placed in damp leaves that I took from the pool. I hope they may reach you alive.* * The two were very much alive on arrival in Ithaca. When I opened the carton on my desk one fell out, ran over the edge and fell into my wastebasket, where I had to chase it around among scraps of loose paper to get it again. J. G. N. t Cordulcgtistcr iliadcniu. Ix, '49J ENTOMOLOGICAL NEWS 17 Indio, California, December 5, 1948. On July 26, 1948, I took off on my expedition to the Great Basin Desert. On the front of my army carry-all hung a desert water bag containing two living half-grown naiads of Oplo- nacschna annata. I took these along with me in hopes that one or both might mature and emerge during my study trip. Be- tween July 26 and August 22, I travelled 3,100 miles through the deserts of southeastern Utah, Great Salt Lake Basin northwest of Great Salt Lake, northern Nevada, and back to Tucson ; and the naiads were as lively at the end of the ardous journey as at the commencement a month before. During this period they had no food. Unfortunately on September 11-12 I had to make a bus trip to southern California and upon my return discovered that the water bag had dried out from lack of attention and my two Oplonacschna naiads were dead and desiccated. On several other occasions the water was gone in the bag but the naiads survived but this time the bag dried out completely and they perished. However these facts show that they are unusually well adapted to the vicissitudes of life in the wooded canyons of southeastern Arizona. There almost any summer they must hide amongst the clumps of damp leaves in drying out pools awaiting the summer rains that will send water running down again. New Ant Hosts of the Fungus, Laboulbenia formicarum Thaxter M. R. Smith (Proc. But. Soc. Wash., vol. 48. 1946: 29-31) published a list of 18 different forms of ants known to be hosts of Laboulbenia formicarum Thaxter in the United States. I have seen the fungus on two additional forms, namely Lasius nigcr var. sitkaensis Pergande (all castes, collected at Logan. Utah by G. F. Knowlton) and Formica parcipappa Cole (col- lected at Nampa. Idaho by the writer). A. C. COLE. Department of Zoology and Entomology, Universitv of Tennessee.

THE LANCASTER PRESS, INC., Lancaster. Pa. ENTOMOLOGICAL NEWS VOL. LX FEBRUARY, 1949 No. 2 Frederick B Isely (1873-1947) One of the leaders in the investigation of the ecology of the orthoptera, Frederick B Isely, died Decemher 30, 1947, at San Antonio, Texas. Professor Isely was horn of Kansas pioneer stock June 20, 1873, at Fairview, Kansas. After education at Fairmount College and at the University of Chicago and a varied teaching experience in high schools and colleges, he became a college administrator in 1920, serving as dean, first of Culver-Stockton College and, later, Texas Woman's College. He returned to full-time teaching in 1931, at Trinity University, and was associated with this institution until his death, though his nominal retirement came in 1946. On the occasion of his retirement, Trinity awarded him the honorary Sc.D. degree. The first important research engaged in by Dr. Isely con- cerned the orthoptera of Kansas, but this interest was re- placed for a time by his studies of the distribution and migration of fresh-water mussels, this investigation being sponsored by the U. S. Bureau of Fisheries. After an interval in which teaching and administrative work eliminated research. Dr. Isely returned to his first interest, orthoptera. From the time he gave up administrative responsibilities until his death he was engaged in a continuous program of research on the ecology of the Acri- didae and Tettigoniidae. Among the important achievements coming from this series of studies was the clear experimental demonstration that many orthoptera have highly specific food habits. Associated with this was the rather detailed correlation between mandibular morphology and food habits. Incidental to major investiga- tions, but creating a great deal of discussion at the time of publication, was the experimental demonstration of the advan- (29) 30 ENTOMOLOGICAL NEWS [Feb., '49 tage of concealing coloration in protecting grasshoppers from predation by birds. At the time of his death Professor Isely was organizing in manuscript form his notes on the food habits of the Conocephalinae. This material clearly suggests that the carnivorous feeding of the meadow-grasshoppers, previously considered abnormal, is a part of the normal behavior of these insects. That such a research program was carried out in a college where every instructor had a heavy teaching load, and Professor Isely was the only teacher of biology during most of these years, suggests a remarkable achievement. It is fortunate that recog- nition by both the National Research Council and the American Philosophical Society provided the necessary financial support, but the success of the program was certainly due primarily to a dominating curiosity about nature and a remarkable innate faculty for research. GORDON ALEXANDER Occurrence of a European Chalcidoid Hemitrichus rufipes Thomson in North America By GEORGE E. WALLACE, Carnegie Museum, Pittsburgh, Pa. In 1938, among some chalcidoid material taken to the U. S. National Museum for determination, Mr. A. B. Gahan identi- fied a number of pteromalids for me as Hemitrichus rufipes Thomson, until then known only from Europe. The specimens had been collected from windows of the Carnegie Museum as early as 1908. Other specimens were taken later — two in 1939 and one in 1940 — also on windows of the Carnegie Museum. Subsequent attempts to collect the insect on the museum grounds and in nearby Schenley Park have been unsuccessful. How- ever, the span of time covered by the records indicates that the species probably is established in North America. A European specimen of H. rufipes in the collection of the U. S. National Museum bears the doubtful host record of "? Ex bruchus ?". This is the only host record known to me. Ix, '49] ENTOMOLOGICAL NEWS 31 Some New Species of the Genus Volucella By F. M. HULL, University of Mississippi Recent studies of American Syrphid flies have disclosed a number of species of Volucella which appear to be undescribed. This paper presents the descriptions of these species. The types are in the author's collection. Volucella belinda n. sp. A greenish to bluish black species. Related to pinkusi Curran but distinct in the reddish brown ground color of the face and the black first abdominal segment. The mesonotal pile is chiefly black in front of the suture. Length 10 mm. Male. Head: the face and cheeks are reddish brown, sepa- rated by a distinct black stripe. The upper part of the face is black, bearing yellowish white pollen. Pile of face yellowish white ; front black with black pile ; vertical pile black. The an- tennae are reddish brown, the elongate third segment gradually and uniformly tapering until it is distinctly narrow apically ; it is faintly darker dorsally and apically. The arista is yellowish bas- ally, black apically, with twenty-four long rays. Eyes not flat- tened, the upper facets but little enlarged. Ocular pile light red- dish brown to brownish yellow, quite thick and abundant above and extending nearly to the bottom of the eye. Thorax: the mes- onotum and scutellum are black with extremely strong opales- cent greenish reflection which becomes coppery to purple where the light strikes it. The pile of the mesonotum is chiefly black and very fine and abundant. There is considerable pale pile how- ever, just behind and medial to the humeri arid viewed from the rear there is an obscure but rather broad stripe of scattered yel- lowish white hairs mixed in with black along the lateral margin of the mesonotum. There may be discerned in some specimens slender linear stripes of pale pile, three in number lying anteri-. orly on the middle of the mesonotum. There is some short pale pile on the' posterior half of the mesonotum mixed in with the long black pile. Notopleura shining black, the upper wing mar- 32 ENTOMOLOGICAL NEWS [Feb., '49 gins and the lateral margin just medial to the notopleura also shining black. Humeri brown, post calli brown, the scutellum with a distinct, complete, preapical depression but no basal flat- tened areas. The depression is granulate. The pleura are shin- ing black and black pilose. The bristles of the thorax are black ; there is one on the mesopleura, four on the notopleura, three above wing, three on post calli, none in front of the scutellum and from eight to ten upon the scutellar margin. The ventral scutellar fringe is black; squamae dark brown, the fringe and border similar. Legs: quite black,, only the extreme apex of the anterior and middle femora and extreme base of their tibiae dark brown ; pile of legs black. Wings : strongly tinged with brown, fading away into a lighter brown along the posterior margin. There is a slight trace of yellowish color mingled with the brown in the costal cell, the first basal cell and the stigmal portion of the subcostal cell which is broken by a minute, diagonal, brown line. Marginal cell narrowly closed. Abdomen: first segment quite black, the remaining segments bright shining bluish or green ; the pile is thick, abundant and yellowish white, except narrowly along the posterior margin of the second segment, more widely along the posterior margin of the third segment, and, except for a few black hairs on the apex of the fourth segment. Hypopyg- ium black and black pilose. All the sternites metallic bluish cell widely open. Female. Similar to the male, the front polished shining black with shallow concave depression across the middle. Marginal cell widely open. Holotypc: male, allotype, female, one male paratype and four female paratypes all from Nova Teutonia, BRASIL, collected by Fritz Plaumann, Jan.— April, 1948. Volucella opeostoma n. sp. Very similar to pica Schiner but distinct in the direction of the conical epistoma which points downward and not forward ; also in the lack of black vittae upon the thorax, the absence of the wide black bands upon the abdomen and with a differently shaped antennae. Length 10.3 mm. Ix, '49] ENTOMOLOGICAL NEWS 33 Female. Head: face pointed downward and a little forward into a very long narrow cone. The face is light brownish yellow in color with a diffuse brown stripe proceeding from the eye mar- gin about the middle of the face nearly to the apex of the cone. Front pale yellow and narrow with black pile and the pile of the vertex black. The short sparse facial pile is golden. The an- tennae are pale orange, the third segment elongate, concave dor- sally just beyond the middle and the apex swollen and slightly bulbous. The arista is yellow becoming blackish towards the apex with about sixteen dorsal rays. Pile of eyes distinctly yel- low. Thorax: mesonotum pale reddish to brownish yellow with four subopaque reddish stripes of about the same color as the re- mainder of the mesonotum. The scutellum is concolorous with mesonotum and both subtranslucent. The pile of the scutellum dense and short and black on the disc with a few longer hairs and with a wide band of thick golden pile on the base. Scutellar mar- gin three pairs of strong but long and slender black bristles. Post calli with three pairs of black bristles, base of wing with three, ontopleura with two, mesopleura with one black bristle. The anterior margin of the mesopleura is blackish on half the width except at the upper portion. The sternopleura and hypo- pleura are black except for the anterior portion of the hypopleura and the upper margin of the sternopleura. The coxae are dark brown on the anterior pair, black upon the remaining pairs and their trochanters, and black pilose. Squamae pale yellow with yellow fringe. Legs: femora and tibiae pale yellow, the tarsi orange. The hind tibiae with a distinct, rather wide, black an- nulus in the middle. This ring is blackish pilose and the femora and tibiae are of a deeper and more reddish color than in pica. Wings: tinged with brown on the anterior border including the costal and basal cells. Abdomen: entire abdomen a bright clear, rich, brownish orange and subtranslucent without any black bor- ders upon the posterior margins of the segments but with a wide band of thick black pile on the posterior margin of the second seg- ment, a still wider one on the posterior margin of the third seg- ment which expands into a triangle in the middle of the segment, reaching almost to the base, and which expands narrowly along 34 ENTOMOLOGICAL NEWS [Feb., '49 the side margin almost to the base. Fourth segment with a large, triangular patch of black pile in the middle posteriorly reaching almost to the base, but none upon the lateral margins. This black pile is subappressed and the remaining pile elsewhere is bright golden red and subappressed. Holotype: female, Bambito, Volcan, Chiriqui, PANAMA, Dec. 1946. collected by N. H. L. Krauss and presented to the author. Volucella sappho n. sp. A reddish brown species related to correcta Curran but distin- guished by the pale brownish yellow to yellowish white pile of the eyes in both sexes. In both sexes of correcta the ocular pile is described as black. Length 8.5 mm. Male. Head: face short, dark shining brownish red with yel- lowish pollen confined to the region beneath the antennae but reaching the eyes. Face with a few reddish brown or yellowish hairs on the side. The facial tubercle is low and scarcely darker in the middle. The front is very small and very dark brown with a few pale yellow hairs. The vertex is also reduced until it is practically non-existent in front of the anterior ocellus and behind the posterior ocellus ; its pile is black. Eyes enormously devel- oped, flattened from vertex to front with greatly enlarged facets and with moderately long pale brownish to yellowish white pile. Antennae reddish brown throughout, the third segment very slightly concave. Arista yellowish brown basally, dark brown to nearly black apically with twenty-one long rays above. Thorax: mesonotum and scutellum deep dark reddish brown, the margin of the scutellum perhaps slightly darker. The humeri. noto- plura and the anterior margin of the pleura and the hypopleura. metapleura and posterior pteropleura only slightly lighter in shade. Disc of scutellum opaque with sparse, fine black pile and three pairs of strong marginal black bristles. Ventral fringe blackish. Squamae very dark brown with similar fringe and border; halteres yellowish with an opaque, quite white knob. Pile of mesonotum distinctly yellow on the anterior two-thirds, becoming dark reddish brown above the wing ; it is black in front of the scutellum. There are no prescutellar bristles but the pile lx, '49] ENTOMOLOGICAL NEWS 35 is a little longer and coarser before the scutellum. There are three black bristles on the post calli, three supraalae, two noto- pleura and one mesopleura. Pleural pile narrowly blackish above becoming dark brown and then reddish brown below. Legs: reddish brown, made darker by the very dark brown pile, which is brown rather than black. The tarsal segments are extremely dark brown but not black. The hind basitarsi and the middle basitarsi are more reddish brown. Wings: uniformly tinged with pale yellowish brown, the costal cell more yellowish and the stigmal area yellowish with elongate, diffuse, brown basal stig- mal spot. Marginal cell closed at the costa. Radial sector with seven long black bristles. Abdomen: first and second segments translucent light brownish yellow, the second becoming narrowly and diffusely darker or more reddish brown along the posterior margin, but the difference in shade is slight. Third segment ob- scurely yellowish on either side at the base and extending dif- fusely down nearly half the length of the segment except at the sides and the middle where somewhat darker brown prevails. Fourth segment similar to the third.

First and second sternites and the third sternite narrowly along the base on either side of the middle light trans- lucent yellow ; remainder reddish brown. Female. Similar to the male in general. The front is black with a shallow, transverse depression upon the lower part of the front ; there are longitudinal depressions along the eye mar- gin, above the transverse depression, and there is an extremely faint medial depression on the upper part of the front. There is a more evident, medial, somewhat groove-like depression in the middle of the preantennal callus ; this groove separates two slightly convex, low bullate eminences. Below these swellings there is on either side a diagonal crease immediately in front of the antennae. Scutellum more distinctly yellowish brown bas- ally, darker posteriorly. First and second segments of the ab- domen, their sternites, and the narrow anterior border of the third sternite very pale translucent yellow.

Part XI By CHARLES P. ALEXANDER, University of Massachusetts, Amherst, Massachusetts The preceding part under this general title was published in ENTOMOLOGICAL NEWS 59: 207-214. The crane-flies consid- ered herewith are from various far western states where they were collected in part by myself, in part by my good friends, George F.

Holotype: <$, Sunlight Valley, Sho- shone National Forest, altitude 6,800 feet, September 6, 1948 (Peder Nielsen). Allotopotype: 5, September 4, 1948. Para- topotypcs: 8 J*$, September 4-6, 1948. The type series was secured in a marshy area. I take unusual pleasure in naming this very distinct fly for my longtime friend and co-worker on the Tipulidae, Librarian Peder Nielsen, of Silkeborg, Denmark. Mr. Nielsen visited America in 1948 and spent nearly two weeks collecting in Wy- oming. I am much indebted to Mr. Nielsen for the privilege of retaining the types of this fly. Superficially the species sug- gests Limonia (Dicranomyia) ctcnopyga Alexander and L. (D.) inellcicauda Alexander, but has the male hypopygium very distinct from these and from all other members of the subgenus. The fly was associated in nature with L. (D.) vnlgata (Bergroth) which it superficially resembles, being readily separated by the closed cell 1st M2 and the entirely different male hypopygium. Pedicia (Tricyphona) ampla euryptera new subspecies J\ Length about 16-17 mm.; wing 15.5-16 mm.; antenna 1.8- 1.9 mm. Characters as in ampla truncata Alexander, differing in slight details of coloration and hypopygial structure. Head and thorax clear gray, the praescutum with four narrow brownish gray stripes; scutellum obscure yellow, infuscated medially; dorso- pleural region broadly pale yellow. Wings fully-developed, as shown by the measurements, the venation normal ; membrane light gray, the prearcular and costal fields more yellowed ; veins brown, much darker than in truncata. Male hypopygium with the tergal lobe broader than in truncata, the caudal margin very gently emarginate, the lateral lobes thus formed low and incon- 42 ENTOMOLOGICAL NEWS [Feb., '49 spicuous. In truncata the caudal margin is truncate, without lateral lobes. Habitat. ARIZONA. Holotypc: J\ White Mountains, Al- pine, altitude 8,400 feet, June 23, 1947 (C. P. Alexander).

In the unique type, the venation of the right wing, mounted in balsam, is abnormal in the medial field. Abdomen, including hypopygium, black, more or less pruinose. Male hypopygium with the tergite large, its caudal margin very gently concave. Basistyle not produced beyond origin of disti- styles. Both dististyles unusually slender, simple ; outer style a long yellow rod that narrows gradually into an acute point ; inner style a little shorter and stouter, dark-colored, the tip obtuse.

Habitat. WASHINGTON. Holotyf>c: <$, Stevens Pass, Sno- qualmie National Forest, altitude 4,000 feet, July 8, 1948; swept from mountain hemlock (C. P. Alexander). Although the male hypopygium is quite different from that of other described species, the present generic and subgeneric assignment seems correct. The fly is most like Erioptera (Eni- pcda} tristhnonia Alexander yet is very distinct. In its general appearance, especially the venation, the fly much resembles certain of the small species of the genus Rhabdoinasti.v. Erioptera (Psiloconopa) ecalcar new species J1.

Legs obscure yellow or brownish yellow, the outer tarsal segments infuscated. Ab- dominal tergites brown, the incisures, sternites and hypopygium 44 ENTOMOLOGICAL NEWS [Feb., '49 yellow. Male hypopygium with the outer dististyle bifid, lack- ing the third or intermediate arm or point that is found in mar- garito. Lateral gonapophyses appearing as straight, entirely pale rods that narrow to the simple tips. In margarita these rods are broader, the tips conspicuously blackened and spinulose. Habitat. UTAH.

Inner dististyle a little shorter, a trifle expanded on the outer fourth and here produced into an acute spine on outer margin, the longer apex narrowed to an acute blackened spine. Gonapophysis narrow, blackened apically, terminating in a long slender spine, the subterminal part with abundant microscopic spicules. In villosa, male hypopygium with the outer dististyle slender ; inner style with apex obtuse ; gonapophysis appearing as a flattened dark-colored blade that does not terminate in a spine, the entire outer end provided with microscopic spinules. Habitat. WASHINGTON. Holotype: <$, Hoh River, Jackson Ranger Campground, Olympic National Park, Jefferson Co.. altitude 580 feet, July 22, 1948; swept from sparse vegetation on river bars (C. P. Alexander). The closest relative of the present fly is Erioptcra ( Erioptera) villosa Osten Sacken, especially the western Nearctic race of this, dilatata Alexander. The present insect is readily told by the coloration of the body, legs and wings, and especially by the structure of the male hypopygium, as compared above. A. D.

Transactions, Royal Canadian Institute, xxvii (57) : 3-56, Oct., 1948. Published Nov. 26, 1948. This catalogue lists 186 species for the areas indicated in the title. Where two or more forms, or subspecies, are recognized as occurring therein, each is given the same number, but is dis- tinguished by a different letter, thus Sy in pet nun semicinctnui semicinctnm (Say) is 169a and S. s. occidcntale Bartenef is 169b. This treatment raises the number of forms catalogued from 186 to 196. Incidentally, it is of interest to note that the recognition of two or more subspecies of the same species is confined to the genera Agrion (our old lamented, but unmen- tioned, friend Calopteryx), Aeschna (with the c), Ophiogom- phns, Souiaiochlora, Tctragoncuria, Erytheinis and Sympetrum. Genera with many species, but no Canadian subspecies, are Argia, Iluallagnia, Gouiphns, Lestes, Leucorrhinia and LibcHnla. For each species and subspecies are given : a sequence num- ber of this catalogue, just discussed; the number under which it appears in Muttkowski's Catalogue of the Odonata of North America of 1910; its name and that of its original describer ; its distribution by political provinces within the area of the title (in the case of British Columbia further differentiated into mainland, m, Vancouver Island and Queen Charlotte Islands) ; flight period; Merriam's life zone(s) (here capital letters ''are used when the species finds optimum conditions in the zone indicated, lower case where the species extends only part way into the zone or is scarce there") ; references to "the larger standard works of more recent issue (where the figures are suitable)," in preference "to earlier papers, which may be no longer obtainable or not possessed by the later workers in the field" — "for full bibliographies of species described prior to 1910, the reader is referred to the indispensable pages of Mutt- kowski's Catalogue," even in most cases for the original de- scription ; finally, references to descriptions and figures of the nymph. All this information is compactly given in usually ten or fewer lines for each species or subspecies, clearly spaced and printed. The sequence of the families is Agrionidae, Lestidae, Coena- grionidae, Aeschnidae, Petaluriclae, Gomphidae, Cordulegas- tridae, Corduliidae and Libellulidae. No subfamilies or other divisions of the families, and no subdivisions of the genus 54 ENTOMOLOGICAL NEWS [Feb., '49 Gomphus in the Selysian sense other than Lanthus Needham, are mentioned. A reference list, arranged alphabetically by authors, occupies pages 44-53, index pages 55-56. The author justly remarks in his Introduction : "In Canada our knowledge of the distribution of the species has increased very considerably, largely due to the indefatigable zeal of Dr. E. M. Walker . . . the writer desires to make it clear that at least 80 per cent (probably more) of the information given [here] represents the work of one man : Dr. E. M. Walker. The groundwork of the study of dragonflies in Canada is all his, with some other of us, first and last, helping out by hunting in the corners." Nay more. Dr. Walker's monographs of the genera Aeslina and Somatochlora, based so largely on the Canadian fauna, stand out as the finest works of their kind on Odonata of any part of the world. Mr. Whitehouse has given us a most valuable summary of the Odonata of America north of the 49th parallel, the Great Lakes and New England. Cataloguers of other groups of animals also will obtain useful suggestions for arrangement of their works by looking over his pages. PHILIP P. CALVERT COLEOPTERA OR BEETLES EAST OF THE GREAT PLAINS, by J. Gordon Edwards, 186 pages including 23 plates, cloth Sy2 x 11. Lithoprinted by Edwards Brothers, Inc., Ann Arbor, Michigan, January 1949. Price $3.50 postpaid, order from J. Gordon Edwards, 392 Prairie Avenue, Wilmington, Ohio. In 1930, "A Manual of the Genera of Beetles of America" by Dr. J. Chester Bradley, appeared and filled a long felt need among coleopterists and would be coleopterists. Long since out of print and increasingly difficult and expensive to secure, it left a need for a book covering a wider area than just a small section or state. In the reviewer's opinion, this new book with its key to all the families of beetles east of the Great Plains and other features to be commented upon, fills in great part, at least, this need, and in some respects goes further. It provides a text which not only will prove of great help to the beginning coleop- terist, but will also be very useful to those more advanced. The first nine pages are devoted to such introductory material as size of the order Coleoptera, the function of the book, a very brief and elementary discussion of nomenclature, an explana- tion of what a beetle is, and of the parts used in identification, a paragraph on how to use the key, a page of some general Ix, '49] ENTOMOLOGICAL NEWS 55 Coleoptera references, and finally an alphabetical tabulation of the families of Coleoptera, giving for each family the number of species and varieties in the United States, and also east of the Mississippi River. The key to the families follows and is illustrated by 449 original line drawings on 23 plates, so arranged that the draw- ings are opposite the pertinent pages. The key itself without the plates occupies 21 solid pages with no break between the couplets. Had space allotted to the figures on the plates been used less generously and devoted instead to improving the ty- pography of the keys, it would have made their use much easier. One further criticism of the keys, which may well be a personal idiosyncrasy : A 21 page key is in itself formidable. Broken up into smaller units or series, it would be much easier to handle and follow. The rest of the book, with the exception of an adequate glossary, index and phylogenetic list of the families of Coleop- tera for the region treated, is devoted to a discussion of each of the 136 families, arranged alphabetically. A surprisingly large amount of information is furnished regarding each family. Gen- eral characters are given of adult and larval stages, together with remarks on habits and habitat. Reference is frequently made to the most common genera and species in such a way that at least tentative identification may be made. In fact, in a few instances, even keys to the species are included. Concluding each family discussion are extremely helpful and quite extensive references to additional taxonomic and biologic literature with citations including 1948. All in all the book should find a wide field of usefulness to anyone interested in Coleoptera, be he beginner or advanced student. EDWARD J. F.

THE LANCASTER PRESS, INC., Lancaster, Pa. ENTOMOLOGICAL NEWS VOL. LX MARCH, 1949 No. 3 The Status of the Genus Antineura Melander (Diptera, Agromyzidae) Bv A. L. MELANDER, Riverside, California J Mr. Kenneth E. Frick, a student of the Agromyzidae, of the University of California, Berkeley, has referred to me a problem in nomenclature. I am grateful to him for furnishing some of the following data not available at Riverside. In 1913 (Jour. New York Ent. Soc., XXI: 249) I erected the genus Antineura for three American species of Agromyzidae (togata n. sp., chlain\data n. sp., and Phytomyza palliata Co- quillett), designating togata as the type of the genus. In 1914 (Ent. Mitteil., Ill: 73) in an article dealing with Namensanderungen Friedrich Hendel called attention to the prior use of the name Antineura by Osten Sacken. in 1881, for a genus of Platystominae, and proposed the name Haploinysa to replace the homonym, without citation of the genotype, though mentioning that he knew an European species of the genus. In 1918 (Arch. f. Naturges., 84A : 114, published in 1920) in the prodomus to his monograph of the palaearctic Agromyz- idae Hendel separated Haplomyza from Liriomyza by the absence of the posterior crossvein. Disregarding the usual cus- tom of retaining the genotype of the homonym, Hendel desig- nated the European .ranthaspis Loew as the type of Haplomysa. In this paper (page 145) Hendel gave a synoptic key to atroni- tcns Hendel (? hetcroftera Loew). .nintliuspis Loew and lati- genis Hendel, as the European species of Haplomyza. Based on their descriptions he mentioned the possible inclusion of H '. balomca Strobl and H. Ticfii Strobl. (57) JUN1 6 1349 58 ENTOMOLOGICAL NEWS [Mar., '49 In 1927 (Zool. Anz., LXIX : 250) in Beitrage zur Systematik der Agromyziden Hendel thought that Haplomyza was poly- phyletic and dismembered the genus, assigning xanthaspis and latigenis "without contraint" to Liriomyza, and atronitens to Cerodontha. Strobl's two species Hendel later placed in the subsequently erected genus Xeniomyza. Thus Haplomyza is left for the forgotten American species alone. In 1932 (Flieg. pal. Reg., Agromyzidae, 59: 198) Hendel re- vived Haplomyza, this time as a subgenus of Liriomyza, again citing xanthaspis as the type. Six additional species were tabu- lated, but as all of them possess the posterior crossvein Hendel's concept of Haplomyza had completely changed. In 1934 (Tijdschr. Ent., 77: 288-290) in Die Larven der Agromyziden, zweiter Nachtrag, deMeijere described a larva and puparium under the name Xeniomyza Hering, n. g. in litt ; X. ilicitensis Hering, n. sp. in litt. He stated that the adult is the smallest known Agromyzid, and would be described later by Hering. In 1936 (the concluding part of the Agromyzidae of the Fliegen der palaearktischen Region, p. 516) Hendel described the adult of Xeniomyza, citing it as Xeniomyza, n.g., Hering in litt, with genotype X. ilicitensis, n. sp., Hering in litt. Disre- garding his former use of the name Haplomyza, Hendel stated that Xeniomyza is the same as the preoccupied Antineura Me- lander. According to nomenclatorial convention Xeniomyza should be credited to deMeijere, 1934, and not to Hendel, 1936, nor to Hering, because ( 1 ) the earlier description of a larva has priority over the later description of the adult, and (2) an author is held responsible for the names and descriptions he publishes and cannot convey authorship merely by citing "in litt." Antineura Melander was originally characterized as differing from Agromyza by the absence of the posterior crossvein, while it differs from Phytomyza in that the costa extends to the fourth vein. The species have yellow humeri and nearly all of the head is also yellow. The postvertical bristles are strong. The base of the anal vein is distinct and the fifth vein is widely divergent. Ix, '49] ENTOMOLOGICAL NEWS 59 In togata the fourth vein ends plainly before the tip of the wing ; in clilaiuydata the end of the fourth vein bends back to terminate at the apex of the wing. The European Haplomyza, as used in the Fliegen der palae- arktischen Region, was separated from Liriomysa by having the humeri wholly brown to black, the head mostly black, only partly on the front and the cheeks yellowish brown, and the frontal orbits about one-third the width of the front. With this charac- terization the American species do not fully conform. Of the seven species placed in 1931 in Haplomyza only xanthaspis lacks the posterior crossvein, so at that time Hendel relied more on color and the structure of the front than on the incomplete venation. Xeniomyza was defined as differing from Liriomysa mainly in the absence of the postvertical bristles, the termination of the fourth vein plainly before the tip of the wing with the costa ex- tending a little beyond the fourth vein, the posterior crossvein completely lacking and the anal vein represented only as a fold. Again the American species do not concur. Although many of the generic distinctions in the Agromyzi- dae are subject to wide variation, it appears that at least three lines of descent are represented here. Therefore the names Antineura Melander, Haplomyza as later construed by Hendel, and Xeniomyza deMeijere-Hendel-Hering do not all apply to only a single genus, i.e. the original homonym Antineura. Under the rules of nomenclature, Antineura Melander is defi- nitely a homonym and is to be replaced by Haplomyza Hendel, 1914, which is a valid name published to take over the species placed in the preoccupied genus Antineura. But the genotype is still togatus Melander. If taxonomically the European spe- cies placed in the modified concept of Haplomyza are not con- generic with the three American species then they require a new generic, or subgeneric, name, for nomenclatively Haplo- myza belongs irrevocably to togatus and its two related Amer- ican species. The genus Xeniomyza has no direct relationship to Antineura Melander, and Hendel's citation of the synonymy is in error. 60 ENTOMOLOGICAL NEWS [Mar., '49 Mr. Frick has investigated the life cycle of Haplomyza togata from a long series of material, and has records of the larva, pu- paria, type of mine and adult genitalia. He informs me that the genitalia are very different from those of either Liriomyza or Phytomysa. An Unnoticed Character in the Saturnioidea (Lepidoptera) By EUGENE G. MUNROE, Institute of Parasitology, Macdonald College, Quebec, Canada The conspicuous armature of spines or warts which charac- terizes the larvae of most of the Saturnioidea has attracted the attention of all workers who have studied this group. The char- acters presented by the more dorsal rows of spines are so strik- ing that the less prominent but equally interesting subventral series (corresponding to primary setae vii in Forbes' system) appears heretofore to have been neglected. It may be assumed that the primitive condition is that in which the subventral row is complete, being represented on each of the segments from thoracic 1 to abdominal 9. This complete distribution is seldom realized, in most genera the subventral spines being absent from some segments, while in a few forms the whole series is suppressed. The resulting distribution pat- terns appear to characterize major groups, and may some day prove useful in a definitive study of the classification of the superfamily. Thanks principally to the magnificent illustrations in Pack- ard's (1905; 1914) monograph, supplemented by descriptions and illustrations in Jordan (1922; 1924), Forbes (l92^), Kirby (1907), and South (1920), and to a very limited extent by my own examination of preserved material, I have been able to as- certain the segmental distribution of the spines of this series in a fairly representative, though not very numerous, array of Ix, '49] ENTOMOLOGICAL NEWS 61 species. Elements of uncertainty have of course arisen due to the necessity for dependence upon illustrations. In many fig- ures the spines could not be seen, because of the position of the larva, lack of contrast in the coloration, or plain omission by the artist of spines which ought to have been visible. Packard al- most never mentions the subventral spines in his descriptions. The paintings by Joutel and the photographs by Watson, how- ever, proved to be particularly useful, and the only major gap in the data is the absence of information concerning the earlier in- stars of Aglia or any of the Arsenura-\ike forms, illustrations of which were not readily available to me, while Packard's descrip- tions are valueless from this standpoint. The following table, summarizing the distribution of the sub- ventral spines in the various forms, tends to err on the side of conservatism, spines which were not clearly visible in the illus- trations or specimens, or specifically mentioned in descriptions, being omitted. In general I have simply avoided reference to any figure in which the distribution of the spines seemed doubt- ful. In the case of abdominal segment 9, however, many figures which were otherwise entirely satisfactory broke down ; accord- ingly, in a number of forms in which no subventral tubercle is listed for segment 9 one will actually be found to be present. This does not apply, I think, to any of the Saturniinae (as here listed) ; I believe that all of these will prove to lack the subven- tral spine on that segment. I am not altogether satisfied as to the accuracy of the data for abdominal segments 7 and 8 in a few of the Hemileucinae, but I have followed the quite unequiv- ocal illustrations, trusting to better informed students to cor- rect any inaccuracies. The later instars of the larvae of Aglia, the Arsenura com- plex, the Cercophanidae, and the Oxytenidae all have the arma- ture greatly modified or suppressed, and the subventral tubercles are not recognizable. The earlier instars of Arsenura, and per- haps of other genera in these groups, have a more complete armature, but I have no information as to the arrangement of the subventral tubercles. Their disposition in the Arsenura group should be of particular interest. 62 ENTOMOLOGICAL NEWS [Mar., '49 Fragmentary as the data are, a characteristic segmental dis- tribution of the subventral spines stands out clearly for each subfamily. A complete series is found only in the African Bunaea complex, where, however, it is of uniform occurrence, Segmental Distribution of Subventral Spines in Certain Saturnioid Larvae Subfamily Species Ins tar Subventral spines present on thoracic segments abdominal segments Citheroniinae Adelocephala isias V 1 to 3 1 and 2 ; 7 to 9 bicolor II 1 to 3 1 and 2; 7 to 9 Anisota rubictmda V 1 to 3 1 and 2; 7 to 9 virginiensis I, II, V 1 to 3 1 and 2 ; 7 to 9 Eacles imperialis I 1 to 3 1 and 2 ; 7 to 9 II 1 to 3 7 to 9 Citheronia splendens ? 1 to 3 1 and 2; 7 to 9 laocoon ? 1 to 3 1 and 2; 7 to 9 sepulchralis I to V 1 to 3 1 and 2; 7 to 9 regalis V 1 to 3 1, 2, and 9 Hemileucinae Automeris pamina IV 1 to 3 1 and 2; 7 to 9 io I 1 to 3 1 and 2; 7 to 9 coresus ? 1 to 3 1 and 2 ; 7 to 9 viridescens ? 1 to 3 1 and 2; 7 and 8 Eudyaria venata ? 1 to 3 1, 2, and 7 Hemileuca maia I 1 to 3 9 nevadensis ? 1 to 3 1 and 2; 7 and 8 juno ? 1 to 3 1 and 2 oliviae ? 1 to 3 1 and 2 Pseudohazis eglanterina ? 1 to 3 1, 2, and 7 hera ? 1 to 3 1 and 2; 7 and 8 Ludiinae Holocera smilax last 1 to 3 none Pseudoludia suavis last 1 to 3 none Ludia delegorguei last 2 and 3 none Bunaeinae Micro gone her ilia ? 1 to 3 1 to 9 Eudaemonia brachyura ? 1 to 3 1 to 8 argiphontes ? 1 to 3 1 to 8 Usta terpsichore ? at least on abd. 3 to 6 Urota sinope last 1 to 3 1 to 8 Nudaurelia dione last 1 to 3 1 to 8 wahlbergi last 1 to 3 1 to 8 Acanthocampa belina last 1 to 3 1 to 8 Gonimbrasia tyrrhea last 1 to 3 1 to 8 Gynanisa isis last 1 to 3 1 to 8 Bunaea alcinoe last 1 to 3 1 to 9 Lobobunnea phaedusa last all tubercles suppressed Pseudobunaea tyrrhena last all tubercles suppressed Ix, '49] ENTOMOLOGICAL NEWS 63 Segmental Distribution of Subventral Spines in Certain Saturnioid Larvae — Continued Subfamily Species Instar Subventral spines present on thoracic segments abdominal segments Saturniinae Saturn ia pavon ia- major last 1 to 3 1 and 2 Copaxa multifenestrata I 1 to 3 1 to 5 Tropaea luna V 1 to 3 1 and 2 Telea polyphemus last 1 to 3 1 and 2 Antheraea yama-mai I 1 to 3 1 and 2 III 1 to 3 none pernyi I to IV 1 to 3 1 or none Rhodinia fugax I 1 to 3 1 and 2 or none II to IV none none V all tubercles suppressed Dictyoploca japonica I 1 to 3 none IV 1 to 3 none Cricula trifenestrata V 1 to 3 none Attacus atlas V 1 to 3 1 and 2 Callosamia promethea III 1 to 3 none V 1 to 3 1 and 2 angulifera IV 1 to 3 none Rupackardia calleta I to V 1 to 3 none Rothschildia jorulla I 1 to 3 none II to V none none orizaba III none none Platysamia spp. II to V 1 to 3 1 and 2, or 1, or none Archaeoattacus edwardsii ? 1 to 3 none Philosamia cynthia I to V none none except in the Lobobiinaca group, in which the whole armature is lost. This would argue for a primitive position for the Bunaeinae, also indicated by the retention of distinct maxillary rudiments in some of the genera (Eiidaemonia, Micragone). In the Citheroniinae, the other group in which distinct (and sometimes functional) maxillary rudiments are retained, the subventral spines have been lost from the segments which bear the mid-abdominal prolegs. A similar pattern is evident in the Hemileucinae, with the addition of a tendency for the loss of the spines from the posterior three segments. In the otherwise very dissimilar Ludiinae and Saturniinae, the larvae agree in having lost all the subventral tubercles be- hind the second abdominal segment. There is also a tendency 64 ENTOMOLOGICAL NEWS [Mar., '49 toward suppression of these tubercles on the anterior segments, to an extent which varies, sometimes in the same instar of the same species. One, and perhaps a very significant, exception is found in the first instar larva of Copaxa multifenestrata, as de- picted by Joutel in Packard (1914). It is doubtless dangerous to base a general conclusion on a single drawing, but the sug- gestion is strong that in the Saturniinae the posterior subventral tubercles were lost before the middle ones. This would preclude any direct relationship with the Hemileucinae, whose affinities would on the contrary appear to be with the Citheroniinae. The Copaxa larva is also primitive in showing no trace of a displace- ment mesad of the dorsal tubercles of the eighth abdominal seg- ment, and of course South America is a well known asylum for primitive forms. The Saturniinae and Bunaeinae are at opposite extremes in the number of subventral tubercles, a fact which provides addi- tional support for their separation, proposed by Packard long ago on the basis of differences in the early stages. In spite of the close similarity of the adults, we can hardly derive the Sa- turniinae directly from the Bunaeinae, for the latter are more specialized than Copaxa and other primitive Saturniines not only in having the dorsal tubercles of the eighth abdominal seg- ment fused in the mid-line, but also in the general exaggeration of the larval armature and in having lost the faculty of spinning a cocoon. It is easier to assume that both groups arose from a common ancestor which spun a cocoon, and in which the sub- ventral series of tubercles was complete and the dorsal pair on the eighth abdominal segment separate.

A New Species of Andrena from Texas, with De- scriptive and Synonymical Notes on Andrena belfragei Cresson (Hymenoptera : Apoidea) By U. N. LANHAM, Department of Zoology, University of Michigan The new species described herein is based on a series in the United States National Museum which had been given a manuscript name by Viereck. The unusual color pattern of the female in this species, approached by only one other species in the United States, makes it easily recognizable in our fauna. Andrena dolomellea new species Female. Integument mostly ferruginous, with details of coloration as follows : clypeus, adjacent areas of face, base of mandibles, scape, pedicel, first flagellar segment, and lower one- half of cheeks ferruginous, rest of head black ; mesoscutellum, metanotum, lower one-third of pleura, and dorsal surface of pro- podeum with strong feruginous markings and tints, rest of thorax black, legs entirely ferruginous ; anterior terga feruginous, pos- terior terga becoming blackish ; all pubescence rich fulvous. Clypeus closely, irregularly, and rather weakly punctate, the lower half slightly shining, with a poorly developed median ridge ; facial fovea wide above, occupying more than three- fourths distance between eye and lateral ocellus, terminating at about level of clypeal margin ; process of labrum large, broadly truncate, truncature slightly concave; mandibles ordinary, with ventral membraneous flange short ; antennae with segment 3 66 ENTOMOLOGICAL NEWS [Mar., '49 about equal to 4 + 5. Mesoscutum with moderately short pubes- cence, not nearly dense enough to obscure integument, integu- ment reticulate, with dense, large, but rather weak punctures; mesoscutellum reticulate, with sparse punctures ; metanotum strongly protuberant ; enclosure of propodeum reticulate, with a few weak, irregular wrinkles above ; propodeal corbiculum with dorsal fringe well developed, no anterior fringe, but hairs of anterior portion branched, interior with dorsal one-half hairy; tibial scopa copious, hairs of outer face simple, trochanteral floccus imperfect, middle basitarsus not conspicuously widened at middle ; wings uniformly and strongly darkened, stigma black, moderately slender, first recurrent nervure ending slightly be- fore middle of second submarginal cell. Terga strongly punc- tate, first tergum with few punctures on elevated portion, closely punctate on depressed posterior margin, remaining terga closely and evently punctate, with punctures of fourth tergum becoming indistinct ; caudal fimbria bright fulvous ; pygidium broadly rounded at apex. Length 13 mm., forewing 11 mm. Holotypc female: Willis, TEXAS, April, 1903 (Bridwell). Male. Black, except legs and most of terga ferruginous; pu- bescence fulvous. Head with pubescence of face rather short; cheeks somewhat wider than eyes, broadly rounded ; mandibles moderately long, decussate ; antennae with segment 3 about equal to 4. Wings lighter than in female, but still well darkened, especially apically. Tergal sculpture about as in female. Geni- talia with tips of parameres long, slender, parapenial lobes mod- erately produced, broad ; sagitta with sides not excavated, widened for about half its length ; tip of eighth sternite moder- ately and evenly expanded, apical margin slightly concave. Length 11 mm., forewing 9 mm. Allotype male: same data as holotype. Paratypcs: 2 females, same data as holotype, one bearing an additional label "Cra- tacgus" ; one female, Fedor, Texas (Birkman) : 1 female. Mound, Louisiana, 2 April 1907 (F. C. Bishopp) and one male, same lo- cality, 7 March 1907, on turnip (Bishopp). Ix, '49 I ENTOMOLOGICAL NEWS 67 In spite of its bizarre appearance, produced by the ferruginous markings of the face, thorax and abdomen, this species is struc- turally a normal member of the vicina-hilaris series, as shown by the imperfect trochanteral floccus, simple hairs of the scopa, and slender parameres of the male genitalia. It is most like hilaris Smith, differing in the much more closely punctured terga and the larger size. A. mellea Cresson, the only other North Ameri- can Andrena known to me to have ferruginous markings on the thorax, has the posterior spur of the hind tibia strongly bent and flattened basally (linear in dolomellea}, and has the pleura coarsely sculptured, therefore belonging to the group of A. ar- gemonis Ckll. and A. prunorum Cockerell, a group not at all re- lated to the present species. A. dolomellea is another example of ferruginous members of an otherwise black series of bees occurring in the southern United States. The subgenus Pterandrena, elsewhere a group of black bees, has at least one reddened species in Southern Kansas and Texas. Andrena belfragei Cresson Andrena belfragei Cresson, 1872, Trans. Amer. Ent. Soc. 4: 256, female. Andrena brunnh'cntris Cresson, 1872, Trans. Amer. Ent. Soc. 4: 258, male. (New synonym.) Andrena te.vana Howard (not Cresson), 1901, Insect Book, plate 4, fig. 7. In order to eliminate the possibility that A. dolomellea might be the same as A. brunnivcntris, described very briefly by Cres- son from a single male, Dr. Karl V. Krombein compared the al- lotype of dolomellea with Cresson's type for me, and found them to be distinct. Mr. P. H. Timberlake further investigated the matter, and found in the collection of the U. S. National Mu- seum a male specimen from Texas ("Collection Belfrage") which had been determined by Ashmead as A. belfragei Cresson ; Mr. Timberlake compared it with the type of brunniventris and thought them to be the same. This male specimen is the mir figured by Howard in the Insect Book, plate 4. figure 7, as ./. tc.vana. Comparison of the specimen with a female belfragei 68 ENTOMOLOGICAL NEWS [Mar., '49 loaned by the U. S. National Museum (from "Tex., Collection Belfrage") leaves little doubt that it is actually the male of this species. A. bcljragei belongs to a group of species related to Andrena carlini Cockerell, characterized by the perfect trochan- teral floccus of the female and the expanded tips of the parameres in the male genitalia ; otherwise, the group closely resembles the vicina series. The species is characterized in this group by the densely and strongly punctured abdominal terga ; it agrees with A. viburnella Graenicher in this respect, and further study may show viburnella to be only a darker (black instead of slightly red- dened) northern race of bcljragei. Monarch Butterfly Migrating in Botetourt County, Virginia By JOHN H. FALES, U. S. D. A., Agr. Res. Admin., Bureau of Entomology and Plant Quarantine At noon on September 28, 1941, while driving north on Route 1 1 about 5 miles from Roanoke, Virginia, we noted mon- arch butterflies (Danaus plexippus L.) flying across the high- way to the south. It was a clear day with a temperature of 90° F., and a southerly breeze was blowing. When we stopped we saw 25 butterflies in several minutes and in one 60-second period noted 6 crossing the roadway. Nine more crossed the highway in less than a minute. These insects flew at an alti- tude of 2 to 20 feet, crossing the highway at about 7 per minute at this point. This was at the rate of 420 per hour. A heavy migration was definitely in progress. As we continued our journey we saw numbers of dead mon- archs on the highway. At Troutville, Virginia, we counted 9 monarchs lying on the highway within a quarter of a mile. Proceeding northward to Natural Bridge and Lexington, Vir- ginia, we saw other monarchs in flight and on the highway. We saw several on Blue Ridge Mountain and on Mt. Long at an elevation of 2,000 feet or more. Ix, '49] ENTOMOLOGICAL NEWS 69 Some Observations on Megarhyssa (Hymenoptera, Ichneumonidae) By P. W. FATTIG, Emory University, Emory University, Georgia On June 25, 1947, Professor J. T. Darlington took me about two miles from the Emory University campus to a beech tree on which he and Richard Smith had found two Megarhyssa inacnirus (Linn.) and one M. atrata (Fabr.) ovipositing on May 20th. Mr. Smith returned to this tree on May 30th and found four AI. macnirns and one M. atrata ovipositing. This tree was heavily infested with Megarhyssa and Treuic.i' colurnba (Linn.). I counted 217 emergence holes on the ex- posed, decayed portion, which was about three feet high, thirty inches wide at the ground and twelve inches wide at the top. On July 27th I observed a specimen emerge with the ovipos- itor separated into three pieces for nearly an inch. I was under the impression that there were only two sheaths and an ovipos- itor, not knowing that the ovipositor itself was made up of three valves. After this discovery, I worked about twenty hours trying to separate the ovipositors of nine specimens. I suc- ceeded in getting three specimens separated entirely, and two more almost entirely separated when one of the valves broke off. On August 4th I began marking the wings of twelve Mega- rhyssa atrata females with white duco paint. All of the marked specimens returned to the tree and oviposited at least twice, number 5 ovipositing twelve times, and number 8 nine times. Number 5 oviposited three times within three hours. Two large decayed roots about six inches apart, extending out from the base of the tree, gave a good chance to get many close-up views of the position and operation of the membrane within the sixth and seventh tergite in relation to the sheaths and ovipositor while the insects were inserting and withdrawing the ovipositor. I was able to get my eyes within six inches of the extended membrane, since Megarhyssa practically always oviposited with the head downward. The looped ovipositor ex- tends the membrane, with the two sheaths within the membrane 70 ENTOMOLOGICAL NEWS [Mar.. '49 during the drilling or inserting process ; then as the drilling nears completion, the circle formed by the sheaths becomes smaller and smaller until very little can be seen, when they give a sort of flip and appear on the outside of the membrane, with one sheath on either side. Thus, when the ovipositor is being inserted, the sheaths are on the inside of the membrane, but when withdrawing, the sheaths are on the outside. On April 30th, 1948, I painted twelve male and seven female M. atrata, and continued painting female M. atrata until May 12th, when I painted the eighteenth female. I saw all of the marked females return and oviposit except numbers 8 and 15. Number 2 oviposited only four times, while number 6 oviposited fifteen times until June 1st, when the observations were discon- tinued. I do not know how many times these marked speci- mens returned and oviposited while I was not observing the tree. On May 1st I observed three male M. atrata with about one- half inch of their abdomens inserted in one hole, with several other males trying to insert the end of their abdomens. About every 10 to 12 seconds the three males would give their wings and abdomen a quivering jerk. After fifteen minutes the three males withdrew their abdomens, and in two minutes a female M. atrata appeared at the entrance of the hole and crawled out ; thereupon one of the males mated with her at once. While this was going on there was another group of male M. atrata about one foot farther down on the tree, going through the same move- ments. The second female appeared twelve minutes later. I counted 32 males in the two groups, all being M. atrata, except 3 M . macrurus, and 2 M. greenei Vier. The males had become so tame that I was able to get within a foot or two of the tree without disturbing them. On May 2nd one male M. atrata began trying to insert its abdomen into a small hole in the wood at 7 :50 A.M., a second at 7:53, and a third at 7:58; one male withdrew his abdomen at 9 :00, a second at 9 :20, and a third at 9 :22 ; the head of a female M. atrata appeared at 9 :24, and she crawled out at 9 :28 and mated as soon as she was out of the hole, and apparently mated Ix, '49 I ENTOMOLOGICAL NEWS 71 twice while crawling up the tree. There was great confusion amongst the 12 to 15 male M. atrata present. At 9:30 A.M., May 3rd. number 3 male M. atrata was ob- served with its entire body inserted in a hole with only the white painted tip of the wing exposed. He withdrew at 9 :47, and a female M. atrata crawled out of the hole at 9 :54, when another male mated with her. I also observed three other males with only the tip of the wing extending out the hole. I presume that these males were trying to enlarge the holes so that the females could emerge. At 12:30, May 3rd. I observed number 3 female M. atrata with her entire body inserted in a hole, with only about half of her wings protruding. The abdomen was withdrawn at 12:48. and the sheaths at 12 :53, the abdomen was again almost en- tirely inserted at 1 :16, and was not withdrawn at 2:00. when I had to leave the tree. At 3 :00. when I returned, the abdomen was again withdrawn, and at 3 :15 she inserted her abdomen for the third time. I also observed number 7 and number 10 with their entire bodies inserted with only the tips of their wings ex- posed ; and number 6 and number 9 with their entire bodies in- serted with the sheaths and the tips of their wings exposed. During 1948 Megarhyssa atrata (Fabr.) was the predomi- nant Megarhyssa at the beech tree. During July 1947 I col- lected 36 specimens of M. atrata, 32 of M. macrurus (Linn.) ; M. hinator (Fabr.), and 18 of M. greenei Vier. From July 20th to August 22nd, I collected 28 specimens of Trciuc.v co- luniba Linn, and saw many more while observing the Mega- rhyssa. They would emerge and drop to the ground amongst the beech leaves, and then almost at once they were off in a flash. I observed only one Tremex ovipositing, and this was at 6:00 A.M.; possibly I was late in getting out to the beech tree. Sometimes there were as many as fifteen female Megarhyssa on this tree at a time, with as many as nine ovipositing at one time. 1 wish to thank Dr. H. K. Townes for determining the Mctjarhyssa and Trcinc.r. and for criticizing the manuscript. 72 ENTOMOLOGICAL NEWS [Mar., '49 Notes on Two West Indian Mutillidae (Hymenoptera) By KARL V. KROMBEIN, Bureau of Entomology and Plant Quarantine, Agricultural Research Administration, United States Department of Agriculture Some years ago Mickel (Psyche, 35: 27, 1928), in a list of West Indian Mutillidae, assigned the Jamaican Sphaeroph- thahna cargilli Cockerell (Psyche (suppl.), 7: 16, 1895; 5) to Dasymutilla. A recent study of the type, in connection with the identification of two females submitted by C. Bernard Lewis, curator of the Science Museum of the Institute of Jamaica, shows that the species is more properly referrable to Pseudo- methoca (new combination), because of the large qviadrate head, elongate first flagellar segment, and absence of carinae delimit- ing a pygidial area. The erroneous assignment to Dasymutilla was undoubtedly due to the character of the first abdominal tergite, the apex of which has a somewhat diskiform appearance as in certain Dasymutilla. The species was omitted from Schuster's key (Bui. Brook. Ent. Soc., 40: 7, 1945) to West Indian Pseudouictlioca because of the erroneous generic assignment. The species is apparently closest to P. olgae Schuster from St. Croix, but is immediately separated from it and the other West Indian species by the broad ferruginous stripes laterally on the posterior part of the dorsum of the thorax, and by the almost totally ferruginous first abdominal segment. Eplmtopsis trinidadcnsis Ashmead is also omitted from Mickel's list of West Indian species, presumably because he argues (Bui. 143, U. S. Natl. Mus., p. 32, 1928) that it is in- valid since it was never described. I cannot agree with this interpretation, for Ashmead states (Canad. Ent., 36: 6, 1904), "Metathorax with the hind angles dentate, clothed with a dense silvery-white pubescence; scutellum bispined. (North and South America) . . . Ephutopsis Ashm., gen. nov. (Types E. trinidadensis Ashm., and M. odontoplwra Cam.)." These char- Ix, '49] ENTOMOLOGICAL NEWS 73 acters serve as the specific as well as the generic description. The type, a male from Trinidad, West Indies, July 1899 (F. W. Urich), is before me, and is herewith placed in the genus Ephuta (new combination). Schuster (Rev. cle Ent., 16: 190, 1945) considers Ephutopsis to be at most a subgenus of Ephuta. If the former is valid, it must be used for the group containing odontophora, its genotype, whereas trinidadensis belongs to the group containing furcillata Mickel and forceps Schuster. The following brief notes will serve to amplify Ashmead's description of trinidadensis and aid in its identification. It ap- pears closest to the Cuban furcillata Mickel, agreeing with that species in the hyaline wings with infumated apical margins, the absence of black pubescence and the presence of a pair of teeth on the scutellum and a median tooth on lateral margin of dor- sum of propodeum. The following points of difference from furcillata are apparent from Mickel's description of that species (Psyche, 35: 25-6, 1928) : Length 6.2 mm.; seventh sternite creamy on basal half ; second sternite without an apical band of silvery hairs, these present only laterally ; first segment of flagel- lum three-fourths the length of second (almost equal in furcillata) ', front and vertex with coarse, contiguous punctures (moderate scattered ones with granular interspaces in furcil- lata) ', second tergite with circular, subcontiguous punctures (elongate ones in jurcillata}. Review INTROGRESSIVE HYBRIDIZATION. By Edgar Anderson. John Wiley & Sons, Inc., New York. Chapman & Hall, Limited, London. 1949. Pp. ix + 109. Price, $3.00. A good new name for an old concept often serves both to advertise and to integrate the idea. "Introgressive hybridiza- tion" has been practiced by plant and animal breeders and has been recognized as at least a partial explanation for variation in natural species since early times. It was not until 1938 that the name was given in an article by Anderson and Hubricht 74 ENTOMOLOGICAL NEWS [Mar., '49 (Am. J. Botany, 25:396-402) in which the process was spe- cifically discussed. As an example drawn from animal breeding, a dominant trait occurring in one breed may be transferred to a second breed by crossing followed by grading. The first generation hybrids are backcrossed to the second breed, their progeny showing the desired trait are selected and again backcrossed, and this process is continued until the mongrels come more and more to resemble the "recurrent" parental breed, except for the desired trait which is retained each generation by selection. In poultry, colors may be thus transferred from one breed to another. As a natural process, white spotting or other markings may thus infiltrate into a wolf population after crossing with dogs and the recessives blue eyes or red hair of white human stock may be transferred to the negro race, cropping out after many generations, as if by mutation. Dr. Anderson's book deals with plant material under "nat- ural conditions," that is outside the laboratory and the breeding plot. These conditions include not only normal habitats to which the organisms are adapted and which tend to keep races or species distinct, but also abnormal environments due to fires, floods or hurricanes or to human activities producing clearings, dumps and garbage piles, as niches in which "hybrid swarms" may develop with new combinations of characters segregating after crossing. As a typical example of introgression, a summary is given (Chapter 1) of the results of intensive studies of variation in Irises in the Mississippi delta after natural crossing of two widely distinct species. Man has there "hybridized the habitat" giving an opportunity for an appreciable number of segregating types to survive. The Ecological Basis (Chapter 2) and The Genetic Basis (Chapter 3) of Introgression are discussed. Normal environ- ment and normal heredity tend toward keeping races and species distinct but permitting a small amount of genie flow after crossing. Several pages are devoted to the cohesive Ix, '49] ENTOMOLOGICAL NEWS 75 effect of genetic linkage. Here the reader will find some rather obscure mathematics, which, in the opinion of the re- viewer, might better have been either more fully elaborated or else omitted. As it stands, it appears somewhat unconvincing since some of the premises are apparently made up to suit the case and there are errors at least of omission in the line of argument. The general thesis that linkage has a cohesive effect, is, however, sound. The author fails to mention several genetic factors other than linkage that may be equally significant as cohesive agents. The section on Character Association as a Criterion of Hybridity should be of interest and value. Introgression in Finite Populations (Chapter 4) gives us more mathematics, which is here clearly, adequately and convincingly presented. The discussion of Introgression and Evolution (Chapter 5) is sound and critical and is treated in such a way that the ideas may be readily grasped. The general conclusions should be of interest to entomologists and the Special Techniques (Chapter 6) may well find application to a study of introgression among insects and other animals. The bibliography is mostly botanical. The noteworthy bio- metrical studies of Alpatov on races of honey bees are cited. These indicate speciation rather than mutation and should furnish the basis for further work of both practical and theo- retical importance. As an Epilogue the author modestly states "How important is introgressive hybridization? I do not know." Bizarre hy- brid swarms are probably less significant than the wide dis- persal of introgressive genes. He emphasizes the paradox "Introgression is of the greater biological significance, the less is the impact apparent to casual inspection/' The reviewer highly recommends the book to entomologists who are interested in the broad biological aspects of their sub- ject. Those who find the mathematics too difficult can skip it. For those who find it intriguing, an elucidating appendix would have been helpful. P. W.

LX APRIL, 1949 No. 4 Ezra Townsend Cresson, Junior Three members of the Cresson family have won commem- oration in ENTOMOLOGICAL NEWS : Ezra Townsend Cresson ( 1838-1926), l hymenopterist and co-founder of the Entomo- logical Society of Philadelphia (name changed to the American Entomological Society in 1867), and his sons, George Bring- hurst Cresson ( 1859-1919), - collector of ants, curator of in- sects at the Academy of Natural Sciences of Philadelphia, 1880- 81, 1886-89, and librarian of the Entomological Society, 1892- 96, and Ezra Townsend Cresson, Jr. (1876-1948), dipterist, associate curator of insects (1908-47) at the Academy, corres- ponding secretary (1932-47), librarian (to 1947) and honorary member (October 23, 1947) of the Society. Ezra Townsend Cresson, Jr., was born in Philadelphia, De- cember 18, 1876, and died at Swarthmore, Pennsylvania. April 8, 1948. His mother was Mary Ann Ridings, daughter of James Rid- ings, co-founder of the Entomological Society, an active collector of insects at Philadelphia, in Colorado, Kansas, Georgia and Virginia. Ezra Junior, therefore, could have received ento- mological genes from both of his parents and his home life could not have lacked environmental encouragement for their activity. In 1881 the Cresson family moved from Philadelphia to Ard- more, and in 1883 to Swarthmore. both in Pennsylvania. From his home in the latter, Ezra Junior attended successively Hilldale Cottage School (Miss Richard's) near Rutledge, Oakdale . NEWS 37 (6) : 161-3, pi. vi (portrait), Juno. 1926.

NEWS 30 (1) : 29-30, Jan., 1920. . 1949 (85) 86 ENTOMOLOGICAL NEWS [April, '49 School, the Friends' School in Media and the Drexel Institute of Technology in Philadelphia. Mrs. Helen J. Tavenner, Reg- istrar of the Institute, has kindly informed us that according to their records "Ezra T. Cresson, Jr., of Swarthmore, Pennsyl- vania, was enrolled as a student at Drexel Institute from Feb- ruary, 1896, until June, 1897, and from February, 1898, until June, 1898. He pursued courses in mechanical drawing, mechanics, shop work and machine construction. He did not receive a certificate or diploma" (Letter of Jan. 21, 1949). After leaving the Institute, he was employed by the George V. Cresson 3 Company, power transmitting machinery, general machinery and founders, whose main office and works were at 18th Street and Allegheny Avenue, Philadelphia, and sub- sequently by the Morse Elevator Works, Morse, Williams & Company, with office at 1105 Frankford Avenue (later West End Trust Building), works at Frankford Avenue, Wildey and Shackamaxon Streets. The Morse Elevator Works were taken over by Otis Brothers & Company, in the same line of manu- facture, and Cresson went with them. He became a life member of the Academy of Natural Sciences of Philadelphia. October 17, 1905, and of the American Ento- mological Society, December 28, 1905, and was elected librarian of the latter body in 1906. The NEWS for October, 1907 (page 363) has a note that "Mr. E. T. Cresson, Jr will visit the western part of the United States this fall. He is making a study of the Diptera and is especially interested in Muscidae." In the issue for February, 1908 (page 55) is the further note that he was "working upon the Dipterous family Ephydridae and would like to examine all the material possible, native or exotic. Present address, -141 Locksley Avenue, Oakland, Cali- fornia." He lived also for a time at Berkeley Hills, California. Thanks to Mr. Thomas B. Steel, Registrar of the University of California at Berkeley, we learn "that Ezra Townsend Cresson, Jr., was admitted to the University of California in January, 1908, as a special student in the College of Natural Sciences. He attended until May, 1908, for one semester. His courses 3 George V. Cresson was a distant relative. Ix, '49 ENTOMOLOGICAL NEWS 87 were taken primarily in Entomology" (Letter of Feb. 8, 1949). In 1908 Charles William Woodworth was associate professor of entomology at the University and some of us recall Cresson's speaking of association with him. After his return from the west, he lived continuously in Swarthmore, his home being at 11 Amherst Avenue in his last years. On October 27, 1910, he was elected associate editor of ENTOMOLOGICAL NEWS and remained on the editorial staff until his death. He edited the Transactions and the Memoirs of the Society from 1926 to 1945. We do not know whether the same consideration — greater activity in the abandoned field — which led his father to transfer his chief attention from Coleoptera to Hymenoptera, induced the son to devote himself to the Diptera rather than to the Hymenoptera. Cresson left a typed list o Lepidoptera, is a synonym of Microbracon lichctor (Say), and (113) ,, 114 ENTOMOLOGICAL NEWS [May, '49 H. brevicornis, a natural parasite of the European Corn-Borer, Pyrausta nubilalis Huebner, is a synonym of Microbracon brevicornis (Wesmael) according to Muesbeck (1925). In a recent letter (March 4, 1949) Muesebeck informs me that "Habrobracon pectinophorae Watanabe was described in 1935 (Insecta Matsumurana, vol. 10 (1 and 2), p. 44). The type series which is deposited in the Hokkaido Imperial Uni- versity, Sapporo, Japan, was reared from Pectinophora yossypi- ella (Saund.), the pink bollworm." In an earlier letter (July 30, 1948) Muesebeck states: "I examined the series of Habro- bracon pectinophorae Watanabe rather carefully but I found no basis whatever for distinguishing this sample from what we have long known as Microbracon hcbctor (Say). It is only natural to expect a parasite of such cosmopolitan Lepidoptera as the Indian-meal moth and the various species of Ephestia and Sito- troga to occur almost everywhere." Mr. A. H. Lankenau, a graduate student for a time at the University of Pennsylvania, became interested in H. pcctino- phorae and had considerable correspondence with occupation authorities in Japan in an endeavor to obtain material. A liv- ing culture was finally received in July 1948, trans-shipped from San Francisco to Philadelphia. Since Mr. Lankenau had meanwhile left the University for other work, the material was trans-shipped to me at the Marine Biological Laboratory, Woods Hole, Massachusetts, where it was received in excellent condition. No differences in form or color could be distin- guished between this stock and the wild type stock of H. jug- landis with which genetics experiments were in progress. Crosses were made with both wild type and with mutant types. The F! "hybrid" females were fully fertile and resembled the dominant wild type parents. Mutant traits introduced from H. juglandis reappeared in F.2 according to expectation. No cytological studies have been made on the material shipped from Japan. However, in view of the fact that chromosomal differences were reported by Inaba, it was thought worth while to make some tests with genes showing linkage in H. juglandis. Accordingly the problem was assigned to Mr. Robert L. Ix, '49] ENTOMOLOGICAL NEWS 115 Cornish, a student at the University of Pennsylvania. Mr. Cornish made crosses of the wild type pectinophorae females with jnglandis males, some of which carried the linked genes stubby antennae, black body color and cantaloup eye color and others carried the linked genes long antennae, honey body color and vcinlcss. wings. Fx unmated females were isolated in each case and F2 impaternate males segregating the different traits were classified and counted. The linkage relationships proved similar to those found in the American material. It may there- fore be concluded that if genetic differences exist they do not significantly involve the chromosomal regions containing the genes tested. Tests for other regions might possibly show- tightening of linkage due to chromosomal inversions, translo- cations. etc. Such irregularities are suggested in different stocks of H. jnglandis. The Japanese material recently re- ceived may also be different in some respects from that investi- gated by Inaba. Distinct races differing genetically are not to be expected in such a cosmopolitan species in wThich the germ-plasm is subject to continuous intermixture. In any case there appears to be no basis for specific distinction between our "jnglandis" stocks, and the Japanese "pectinophorae." Both are specifically iden- tical with Microbracon hebetor (Say).

In Colinicola incarnsi Emerson 1948 and C. numidi- anus (Denny, 1842), the clypeal margin is broad and evenly rounded. C. docophoroides (Piaget 1880) and C. pallida n. sp. each have a narrow clypeal margin which is very pointed. The latter two can be easily separated by a comparison of the male genitalia. FIG. 1.

'49 Late Summer Invertebrates, Mostly Insect, of the Alaskan Arctic Slope By NEAL A. WEBER, Swarthmore College, Swarthmore, Penna. The Alaskan Arctic slope is that part of Alaska draining to the Arctic Sea and is a treeless area. August 19 to September 5, 1948, a brief visit was paid to this region (Entomological News, December 1948, 59 -.253-257). l Snow fell during most of the nights and the temperatures were generally in the 30°'s and 40° 's Fahrenheit. Most of the conspicuous insects had disappeared this late in the season and the present records reflect mainly a sampling of the fauna remaining active at the time. The collections were made chiefly at Pt. Barrow (Latitude 71° 21' North) and at Anaktuvuk Pass on the north front of the Brooks Range in the Endicott Mountains (Latitude 68° 05' North). From the Alaskan Arctic slope there are very few records and these mostly by Riley (1884, United States Polar Expedition) and Johansen, Hewitt, et al. (1918-22, Canadian Arctic Expedition of 1913-18). The records are listed below by phyla, classes and orders of the animals involved, beginning with Annelida and ending with Arthropoda.2 They are of adults unless otherwise stated.

FROST, The Pennsylvania State College During 1948, 160 blackfly adults were separated from a large number of insects taken in light traps operated in twenty widely- separated localities of Pennsylvania. These catches supplied sufficient information for a preliminary report on the abundance and distribution of the Pennsylvania species. Eleven species were taken including several of considerable economic impor- tance. A few records have been added from specimens in the Harrisburg collection.

Approximately 50 species of Simuliidae are known from North America. Thirty-three of these are limited in distribution to the Western United States, Alaska and Canada. Another twelve species are restricted to * Authorized for publication on February 28, 1949 as paper No. 1516 in the Journal Series of the Pennsylvania Agricultural Experiment Station. 130 ENTOMOLOGICAL NEWS [May, '49 the Southern United States, Central America and the West Indies. Only seven distinct species are given in "A List of the Insects of New York." The Pennsylvania records are slightly more extensive. The following species, common in Eastern United States, should also occur in Pennsylvania : Simulium metallicum Bellard, Eusimulium mutatuui (Mall.), Eusiiniiliiiin johannseni (Hart) and Eusimulium aurcuni bracteatnm (Coq.). Some of these were taken in light traps but the material was difficult to identify because no males were captured. Four species deserve special mention. Simulium vittatum Zett. appears to be the most common species in Pennsylvania. This species has a wide range of distribution occurring generally throughout the United States including Alaska and is also known from Canada, Greenland and Mexico. It frequently attacks man and his stock and is generally troublesome. The long period of flight throughout the summer contributes to its special annoyance. Prosimulium hirtipes Fries stands next in importance; how- ever, it has a short period of flight during early spring. Simulium venustum Say is another annoying species but appears not to be as common in Pennsylvania as the above species. One specimen of Simulium hydationis D. & S. was taken at Ohiopyle on June 9. Ohiopyle is located in Southwestern Pennsylvania on the Youghiogheny River in an Austral section of the State. Apparently this species has previously been taken only in Virginia. It would seem from the accompanying table that the females are attracted to light more frequently than the males. In the case of Simulium pictipes Hag, the reverse seems to be true although the number of specimens obtained is too small to draw definite conclusions. In collecting blackflies by the biting method, females would undoubtedly predominate also. The Simuliidae is an important group containing many species that annoy man, attack his animals or transmit certain animal diseases. The blackfly menace has been a bane to fishermen and hunters for a long time and some relief would be Lx, '49] ENTOMOLOGICAL NEWS 131 welcome. The application of D.D.T. to control mosquitoes has shown reduction in the blackfly populations. These facts in- dicate the need for further surveys and more detailed study of the habits of these flies. REFERENCES DYAR, H. G. and R. C. SHANNON. (1927).

By Herbert H. Ross. John \Yiley & Sons, Inc.. New York. Chapman & Hall, Limited, London. 1948. Pp. viii + 532. Price. $6.00. \Ye have here, for the first time in this country, a text that covers practically all branches of entomological science. It begins with a chapter on history in which the emphasis is on the development of entomology in America. Then follows a chapter on the various classes of arthropods, chapters on ex- ternal and internal anatomy, on physiology, and on the life cycle, including embryology, transformation, food habits, re- production and social life. About equal space (228 pages) is then given to the orders of insects, with keys to the principal families. Finally, there is a chapter on ecology, in which cli- matic factors, food, enemies, etc., are discussed, and also a chapter on insect control. In every chapter, Dr. Ross adheres to his aim of presenting the basic facts and fundamental ideas to the exclusion of much detail. The anatomical terminology and the morphological interpretations adopted agree largely with those of Snodgrass, many of whose excellent figures are used as illustrations. The physiological data given are also completely up-to-date. As a text for students in entomology, this book will draw immediate attention to the absorbing interest of many of the approaches to the study of insects that are too often neglected in courses that emphasize wing veins and taxonomy. And for prospective zoologists, a course based on this text will provide general zoological training in a group of animals that is proving so useful in investigations in pure physiology, genetics, cytol- ogy, evolution, etc. The book is printed on glossy paper so that the many illus- trations look very well, with some exceptions. A number of the figures, it may be said, are unnecessarily large and their arrangement is often such that page space is wasted. Should the publishers prove sufficiently far-sighted to invest the neces- sary effort and funds, much could be accomplished by a more careful planning of the illustrations and by devising additional figures that would be more closely coordinated with the text to form a didactic unit. The plan of the book is excellent and it is evident that the author is a master of his materials and has succeeded in present- ing them in a well organized manner. It is the only American text that attempts a balanced presentation of the entire field <>t entomology. — R. G. SCHMIEDER.

Armature in abantis a lower long pointed spiniform, then above it about equally spaced two much shorter spiniforms apically rounded, but in clantoni this arrangement is changed by having the upper spiniform of abantis represented in the majority of cases by a simple small bristle. About 1 out of 20 specimens in clantoni have the armature arrangement of abantis. Due to the amount of variation in the apical outline of the VII sternite of the female in both abantis and clantoni it is difficult to distinguish one from the other. This outline in clantoni is with upper lobe which varies from well rounded to angulate. The outline of the allotype is with upper lobe with flat surface, lower angle angulate, upper angle rounded. The spermatheca is barrel shaped, with crooked finger shaped appendix but without ap- pendage. The new flea measures 2.00 mm. in male, 2.75 mm. in female. Remarks : As early as June 16, 1938 the writer took the fe- male of this flea off Lagurus at Bickleton, Washington but mis- took the specimens for M. abantis. Specimens coming to him from Clanton have been in the ratio of 5 females to 1 male. These fleas have proved plague positive in parts of central Wash- ington. From February through June at least the flea count on these mice is very high. Thrassis gladiolis johnsoni new subspecies The new subspecies is close to Tlirassis gladiolis gladiolis which ranges some 300 miles to the south in southeastern Ore- gon. The writer has no evidence that the range of the two fleas comes closer. The chief difference between the males ot Tlirassis g. gladiolis and Thrassis g. johnsoni is the very promi- nent IX sternite in the new form which if one were to state it in the vernacular "sticks out like a sore thumb." The finger of john- soni is of the general shape of gladiolis but the armature is some- what different, being of 5 major bristles along the posterior border, the two uppermost very long and fairly close together. Midway down the border is a major bristle, which may be directed 144 ENTOMOLOGICAL NEWS [June, '49 downwards. At the lower angle of the border are the usual 2 Thrassis spike-like bristles. The VIII sternite is apically angulate rather than rounded as in other gladiolis. The IX sternite sets well out beyond the other modified segments. The apical bristle is not so spine-like and the customary paired bristles below the apex are grass-blade-like. In the apical outline of the VII sternite of the female the undulation found in the females of other gladiolis is missing. The outline, if not damaged, is nicely rounded. The armature consists of 5 stout bristles. The spermatheca is typically Thrassis. In length these fleas measure 1.50 mm. in male and 2.00 mm. in female. Other interesting data in this study were the rarity of fleas other than Megabothris dantoni and Thrassis gladiolis johnsoni on Lagurus. In some 500 fleas checked the writer found only 4 males of Malaraeus telchinwn (Roths.), a deer mouse flea, 1 male and 3 females of Catallagia decipiens (Roths.), a mouse flea and 1 male and 2 females of Meringis shannoni (Jordan), a pocket mouse flea.

He will continue his teaching, both at the University of Kansas and, during summer months, at the University of Michigan Biological Station. He expects to continue his research program on the aquatic Hemiptera. Having recently published a revision of the Corixidae of the Western Hemisphere, he plans to complete his study of the Corixidae of the Eastern Hemisphere. He is replaced as chairman of the Department of Entomology by Doctor Charles D. Michener, who is continuing studies now in progress on the saturniid moths and plans to continue his principal research studies in the taxonomy, evolution, biology and behavior of bees. Ix, '49] ENTOMOLOGICAL NEWS 145 Agrion versus Calopteryx The NEWS presents below two letters that were received re- cently from England by its Editor Emeritus, Dr. Philip P. Calvert, and that comment upon the article "Calopteryx versus Agrion ; Again ?" by Dr. Erich Schmidt, published in ENTO- MOLOGICAL NEWS for October 1948, pp. 197-206. Following these, there is a reply to Miss Longfield by Dr. Schmidt, and also parts of Dr. Calvert's letter to Miss Longfield that bear on the same subject. British Museum (Natural History) Cromwell Road, London, S.W. 7 How exceedingly tiresome of Dr. Erich Schmidt to have again raised this question of "Calopteryx versus Agrion" (ENT. NEWS, 1948, 59:197), and on insufficient knowledge. There is no question of the date of publication of volume 9 of Brewster's Edinburgh Encyclopedia (Part I. Entomology), in which volume is Leach's article on the Class Odonata of Fabricius. We have the volume in this museum and the date of publication is 1815. Stephens' date of 1810 referred to the date of publi- cation of volume I of the Encyclopedia, which is proved by the following reference in Stephens' Systematic Catalogue of British Insects, 1829, where on page xxvi, under "Authors quoted," the reference to Leach is as follows : "Leach in Edinburgh Encyclo- pedia : articles Entomology and Insecta. Edinburgh. 1810, etc. 4to." Probably Leach's MSS. was ready by 1810, but it was not in print for another five years. Latreille in 1802 (Hist. not. gen. Crust. Ins., Vol. 3, page 287) gives virgo as the "example" for the genus Agrion Fabr. Pos- sibly it is this that some authors consider "obscure," but no one can say the same for Latreille's second reference published in 1810 (Consid. gen. Aniin. Crust. Arach. Ins., page 434). Here, Latreille gives a list of all the genera in his book, each name followed by that of one species, which he says, p. 421, that he designates as the type. There is not the slightest ambiguity on this occasion, where virgo is cited as the type of Agrion. Kirby 146 ENTOMOLOGICAL NEWS [June, '49 was absolutely correct in changing the names as he did, in 1890. That both de Selys Longchamps and Dr. Ris disliked the change of names (who does not?), is beside the point. They did not apply to have the law of priority suspended in this case, nor do I see any reason for supposing that the International Commission on Zoological Nomenclature would have interfered with the pub- lished fixation of the type of Agrion by Latreille.* Personal opinions of regret at the application of the law of priority get us nowhere. The generic name of Agrion for virgo has been widely in use for 59 years, whereas Caloptery.v, it seems, was only generally adopted for 51 years before the pub- lication of Kirby's catalogue. There is, therefore, little differ- ence in the question of "usage." The original fault lay in Burmeister adopting Leach's name instead of Latreille's, in 1839 (Handb. Ent. 2, page 825). The case for Agrion versus Cal- optcryx is clearly proved and all Dr. Schmidt's arguments are useless. CYNTHIA LONGFIELD, F.R.E.S. Holyivell House, Edington, Bridgcwatcr, Somerset Miss Longfield has sent me a copy of her note on the subject of Agrion versus Caloptcryx. At the moment I have not seen the paper by Dr. Schmidt to which she refers, but in the mean- time I would like to add the following comments to her letter, with which I am in general agreement : For those who adhere to the International Rules of Zoo- logical Nomenclature, there can be no doubt that the genotype of Agrion Fabricius, 1775, is Libelhda virgo Linnaeus, 1758, by the earliest designation (Latreille, 1810) ; consequently Cal- opteryx of authors falls as a synonym of Agrion. The International Commission on Zoological Nomenclature has ruled (in Opinions 11 and 136) that the designations of genotypes by Latreille, 1810 are valid designations when they do not conflict with other requirements of the International Rules. * The Nomen. Commission's Opinion 11, says these types should be accepted. l.X, '49] ENTOMOLOGICAL NEWS 147 Calcptcryx Leach, 1815, Brewster's Edinb. Encycl. 9(1): 137 —the date of publication is known to be April 1815 (see Slier- born, 1937, /. Soc. B'ibl. Nat. Hist. 1 : 112). The late R. A. Muttkowski seems to have referred the case of Agrlon versus Calopteryx to the International Commission, and quotes their decision in favour of virgo as the genotype of Agrion (1910, Bull. pub!. Mus. Milwaukee 1 (1): 14-15); but no Opinion embodying this decision of the Commission has been published. Muttkowski's premisses, however, were not valid, being based on the citation of an example f by Latreille, 1803 (1910, ibid.: 26), but this was corrected in a subsequent paper (Muttkowski, 1910, Bull. Wis. Nat. Hist. Soc. 8: 158) where the then Secretary to the Commission is quoted as showing that it is possible to settle the question of the genotype of Agrion (by the designation of Latreille, 1810) without referring the subject to the Commission at all. This no doubt accounts for the Opinion quoted by Muttkowski never having been published by the Commission ; it was I assume withdrawn before publication as being unnecessary. J. COWLEY Mosartstrassc 22. (22) Bonn am Rliein, Very probably we should not have touched this stinging nettle of nomenclature if we had known earlier that which Prof. Hedicke of Berlin, formerly a collaborator of the "Nomenclator Zoologicus," of the Prussian Academy of Sciences wrote us concerning the date of publication of Leach's paper in Brewster's Encyclopedia, stated by C. D. Sherborn with superexactness and published in his "Index Animalium." According to t Mention of a species as an example of a genus docs not constitute a selection of a type (International Rules, Art. 30 II g). This excludes Latreille, 1803 (the correct date is 1 1802-1803 1, for which see Griflin, 1938, /. Soc. Bihl. nat. Hist. 1: 157). There is no warrant for emending Leach's original spelling (.\ilcptcry.r, for he gives no derivation for the name, nor is one obvious from his re- marks. From his statement that "This genus comprehends those Ayr'w- nida with coloured wings" it is only a probability, not a certainty, that he intended the name to he based on KO.\\I- or KaXos and T 148 ENTOMOLOGICAL NEWS [Julie, '49 Hedicke, the matter is more complicated than was mentioned in the foregoing article (Miss Longfield's), the most valuable contribution of which is the statement of the probability that Leach's manuscript was ready by 1810. Now we are not sorry for having written the article, since a further study of the matter brings out other interesting facts that might easily be overlooked. We know of Kirby's error in establishing his "ultra-radical" change of names on the basis of Latreille's paper of 1802, and now we know also, and well, that the later paper of 1810 is in no way better! In a footnote in Trans. VII Int. Congr. Ent., Berlin, p. 559, and in more minute detail in Entom. Rundschau 56, 1939. p. 187 ff., it is stated that Latreille sometimes gave two species names as "types" for one genus, which certainly does not conform to our modern idea of "genotype." For this reason there arises not only a "slightest ambiguity" but a really decided one concerning Kirby's change of name, and he is "absolutely incorrect" in the same manner as the writer of the foregoing article and the mod- ern anachronists such as Muttkowski, Stiles and Cowley. The International Congress of Zoology in Lisbon (1935), however, took the first step in a retreat when it limited the application of its former decision to only those genera of Latreille (1810) that have only one species name as the "type." However, since the foregoing reflections will be valid generally, from a logical point of view, for all of Latreille's genera in his paper of 1810, we may expect that even the God-like International Commission of Zoological Nomenclature will, although perhaps only after a period of reflection, arrive at the next step (a necessary conclu- sion), the entire "suspension" of its somewhat superficially made Opinion 11, an opinion that originated during a period when that honorable group was made up preponderantly of "rigorists of priority." * * I should like also to call attention to the following : In comparing the time in years during which the two names were in general use, Miss Longfield overlooks the fact that for a long time after the appearance of Kirby's catalogue no attention was paid to the change in name, not even in England. The outstanding authorities there, such as McLachlan and K. J. Morton used Caloptcryx all their lives, ignoring Kirby, just as did Ix, '49] ENTOMOLOGICAL NEWS 149 To date, this is still only a dream of the future. However, the present generation has a duty to establish an accord in no- menclature as soon as possible, and the writer believes that the path of "classical nomenclature" will always be better than any other, especially for the younger generation, in order to prevent, in the end, football versus entmology. ERICH SCHMIDT P. 0. Box 14, Cheyney, Pennsylvania. A practical consideration also enters into the nomenclatural question of Calopteryx versus Agrion which I emphasized in my June, 1927, editorial, "Does Familiarity Breed Contempt" (ENT. NEWS 38: 185-6). For some years I have been bring- ing together notes on papers dealing with the chemical, physical and biological characters of waters in which Odonate larvae (nymphs) live. I have just looked over these notes from authors whose names begin with A — D, who have anything to say on larvae of Calopteryx or Agrion, with these results (purely systematic papers are not included) : W. J. Lucas together with the entire faunistic literature of England, so that while these authors lived Calopteryx was in almost universal use in England, that is up until about 1935. Lucas died in 1932, and Morton in 1940. The first attempts to recognize Kirby (by F. F. Laidlaw in 1902) were very feeble and did not succeed even after the publication of Mutt- kowski's catalogue (1911). Not until the newer compilations made their appearance as a substitute for Lucas' work, now out of print, was the mistaken change of name actually effected. Moreover, on the continent of Europe (with the exception of Navas, of all people) Calopteryx is in almost universal use and always will be. Actually, then, Calopteryx has been in general use for about 100 years as contrasted with about 15 years for Agrion. Furthermore, it should be considered, all important monographs, namely those of Selys, Hagen and Bartenef use Calopteryx, not Agrion, and these have more weight than all modern compilations that have an anachronistic foundation. To be sure, the International Rules have as yet found no adequate means of providing nomenclatorial recognition for the old masters who are not now in a position to defend their life's work against modern anachronism and nonsense. This destruction of old, good names without sufficient reason is, it seems to us, one symptom of the "decline of the West." — ERICH SCHMIDT. 150 ENTOMOLOGICAL NEWS [June, '49 ALI SADE, A. 1934.

It will be seen that a majority of these papers use Calopteryx, but I am not concerned with determining how large or how small that majority is. What interests me is that many authors still use Calopteryx. The conclusion I draw is that, to make one's meaning perfectly clear, it is necessary to specify, in each case where the term Agrion is used, just what Agrion means in that case. It seems to me to be advisable to use both names in each case in some such way as this : "Agrion virgo, also known as Calopteryx virgo," Coenagrion pnlclieUuni, also known as Agrion pitlchcllum." A very recent example of this practice is in Col. MacNeill's ingenious paper on "Distribution of dragon- Ix, '49 1 ENTOMOLOGICAL NEWS 151 flies in Ireland" in the Irish Naturalists' Journal, ix (9) for January, 1949, pages 234 and 236. What Ccdopteryx is is known, what Coenagrion is is known. Agrion is the uncertainty. What an unforgivable crime it would be, from the priorist's point of view, to drop Agrion altogether ! ! ! PHILIP P. CALVERT Oviposition of Cryptocephalus confluens Say (Coleoptera, Chrysomelidae) By J. W. TILDEN, San Jose, Calif. On September 26, 1947, a pair of these beetles was taken in copula on a bush of Bacc/iaris pilularis D. C. subsp. consanguinea D. C. (C. B. Wolf) (Compositae. Astereae), at Page Mill Road. Santa Clara County, California. The pair was brought into the laboratory where the beetles were kept for observation in a large vial of thin glass in which a twig of the food plant was sup- ported by moist sand. This type of container has proven very useful for observational work, since the vial may be placed on its side for use under a binocular microscope without displacing the contents. All of the following observations were made un- der binocular microscopes of various powers. An effective closure for the vial is formed by loose cotton which allows free exchange of gases and also some humidity control. For the two days following, the beetles fed on the leaves, cut- ting scalloped fringes on the leaf edges. On the morning of September 29, the pair was again in copula. The female sup- ports and carries the male during mating. The prothoracic and mesothoracic legs of the male are closely appressed to the elytra of the female. Apparently the setose tarsi of these legs adhere to the elytra of the female, and seem to constitute the only means by which the male remains in position. The metathoracic legs trail. The female controls the entry of the male organ by movements of the terminal sternite of the abdomen. In some instances the male attempted to mate for a period of several 152 ENTOMOLOGICAL NEWS [June, '49 minutes before the female advanced the sternite. The female continues to feed during copulation. The first egg was found on the bottom of the vial on Septem- ber 30. The oviposition and subsequent treatment of the egg is peculiar and interesting. The female is equipped with a sulcus on the fifth abdominal sternite which serves, in conjunction with the metathoracic tarsi, to hold the egg. The egg is extruded and is caught by the tips of the tarsi and applied to the sulcus. While the egg is in this position, the female applies a relatively large mass of secretion which forms a mound-like patch on the surface of the egg. The egg is then rotated slightly by means of the tarsi, and another patch of secretion is applied adjoining the first. This process is repeated until the egg is covered with approximately equal rough mounds of this material. The egg is then revolved several times by the tarsi, the legs twitch al- most imperceptibly, and the egg, together with its coating, is flipped out and falls to the ground. The secretion is dull olive in color when first applied, soon darkening nearly to black. After several days, the color changes to a dull brown in the process of drying and remains so without further change. This secreted covering is friable and easily pried away with needles, parting along lines that mark the bound- aries of the individual applications. In drying, the coating shrinks away from the egg to some extent, leaving a small space between the coating and the egg ; that is, the coating envelopes the egg loosely, the egg being free inside the coating. The measurements of the case or coating are about 1.5 mm. by 0.9 mm. The egg is smooth, shining, pale in color, without visible sculpture at a magnification of 30 X, and measures 1.0 mm. by 0.6 mm. in size. The outside measurements of the case are thus 0.5 by 0.3 mm. larger than the egg. The entire struc- ture resembles nothing so much as an old fashioned peanut candy, except for the difference in color. The process of applying the coating requires about twenty minutes to each egg. After the egg is dropped, the female grooms her appendages carefully and raises and lowers the elytra several times. Occasionally the flight wings are raised and vibrated as though the insect were about to take flight, but Ix, '49] ENTOMOLOGICAL NEWS 153 in each case the elytra were lowered again without the insect actually attempting to fly. The manner of oviposition resemhles closely that descrihed by Spruyt l for Sa.vinis sancia Leconte, as far as the application of the primary coat is concerned, but this species of Cryptocephalus, at least, applies only the one coat and does not apply the eight serrated bands of material described by Spruyt for sancia. Neither is the primary layer truncated at one end of the longi- tudinal axis in Cryptocephalus, as described for Sa.vinis. On the contrary, the finished case of Cryptocephalus is quite evenly oval in outline. On September 30, fourteen eggs were laid between 8:00 A.M. and 3:00 P.M., and at 4:30 P.M. the beetles were again in coitu. On October 1, thirteen eggs were laid. On October 2, three eggs were found and the beetles were again seen to mate, at about 4:30 P.M. On October 3, six eggs were laid. No fur- ther eggs were found until October 6, when four eggs were laid. On October 8, a single egg was laid, and no further eggs were obtained, although the beetles were found mating on several oc- casions thereafter. Observed copulations took place in late afternoon or early evening, whereas oviposition was confined mostly to the morning hours. On October 18. the beetles were preserved as specimens for determination, and since it was desired to keep them as in- tact as possible for this purpose, no dissection of the female was made, so it is not known if a residuum of unlaid eggs remained. However, the total output of eggs of another species of chryso- melid, Trirhabda flai'olinibata Mannerheim, the entire life his- tory of which was observed, varied from 43 to 73 eggs over a period of several weeks, so it is barely possible that the forty-one eggs laid by Cryptocephalus conflucns represent a normal number for the species. Verification of this as fact would require additional observations. Spruyt (op. cit.) found that eggs of Sa.rinis sancia hatched in twenty-six days, but those of Cryptoccphalns overwintered, 1 SPRUYT, F. J., Observations on the egg-laying habits of Sa.rinis Leconte. Pan-Pacific Entomologist 1 (4) : 176-178, 1925. 154 ENTOMOLOGICAL NEWS [June, '49 and had not hatched when the project was abandoned in March, 1948, for other more pressing duties. Although the eggs when discarded appeared to be still viable, no embryos were found in them. This difference in hatching time may be due in part to the season at which the eggs are laid. The eggs of Sa.vinis were laid in July. The significance of the application of secretions to the eggs is not apparent. Van Dyke - describes the rearing of larvae of Sa.vinis saitcia from ant nests. Lef roy 3 mentions that larvae of Cryptocephalus have been found to be case bearers (as are those of Sa.vinis). However, I have been unable to locate literature stating Cryptocephalus to be myrmecophilous, nor have I seen any paper indicating that anyone has seen ants transport to their nests the eggs of known myrmecophilous Chrysomelidae. The exact origin of the material that forms the case or coating is obscure. At the present time I am unable to say if it is fecal matter or the product of colleterial glands, but the latter ex- planation seems most reasonable. It seems unlikely that the serrated bands of Sa.vinis, at least, could be formed from fecal matter. Moreover, the true feces excreted by both sexes of Cryptocephalus were much less copious than the material that composed the coating. Coleopterists with whom this matter was discussed differed in opinion on this point, which will re- quire additional study to clarify.

PORTMAN, University of Missouri, Branson, Missouri Several years ago while attempting to classify some Ixodid ticks that had been preserved in 70 per cent alcohol it was found that some means of straightening their legs away from the body was necessary before all their morphological characteristics could be clearly observed. After the following procedure had been developed, it was discovered that the specimens might be glued on insect pins points for display and study, embedded on slides or mounted in many other ways. Then it was real- ized that the stretched ticks were wonderful material for the indoors photographer. It is not known whether the following procedure is entirely original but it seems desirable to describe the technique so that others may be able to take advantage of the method. The materials needed are a supply of ticks, a pair of straight pointed forceps, teasing needle, some microscope slides, some strips of cotton the size of the slides and about one-quarter inch in thick- ness, some strips of fine sandpaper cut to the same size as the slides, and a few rubber bands. Select a tick from the supply and grasp the tick with the forceps along the mid-dorso-ventral line, making sure that none of the legs are held under the forceps. With the fingers of the free hand gently stroke and pull the legs laterally and somewhat anteriorly until the muscles have been relaxed or stretched. This may require a little time to break down the muscle tension. When the legs on one side have been relaxed turn the tick over and repeat the procedure with the legs on the other side. This process must be done gently ; otherwise the pulvilli will be torn from the tarsi, the legs disjointed or pulled from the body. When all the legs have been relaxed, place the tick on a strip of sandpaper with the dorsal side up. Then hold the tick against the sandpaper with a teasing needle and arrange the legs in the desired position. The pulvilli will in most cases 156 ENTOMOLOGICAL NEWS [June, '49 catch onto the sandpaper and hold the legs in the desired posi- tion. Several ticks may be arranged on one piece of sandpaper as long as they do not overlap. Practice and experience is the best guide. Then place another strip of sandpaper over the ticks. On this place a strip of cotton, and then a microscope slide. Carefully turn these over and add a strip of cotton and a slide to the other side. Pick up the slides and wrap them with a rubber band. The cotton will act as a cushion but if the rubber band is stretched too tightly the ticks will be crushed flat and they will lose their natural shape. The slides are then set aside for several days until the ticks are thoroughly dried. At times tickets will stick to the sandpaper, but they can be released by bending the sandpaper slightly permitting the ticks to drop off. The legs of those specimens which were not thoroughly relaxed will sometimes curl up while drying but most specimens will be in the exact position in which they were placed. By using Le Page's glue, or similar medium, the ticks may be mounted on insect pin points exposing either the dorsal or ventral aspects. Balsam slides may be prepared by soaking the ticks in xylol for a few minutes before embedding them or in toluene in preparing a clarite slide. The Man who Stole Beetles Systematists should take warning from the plight of a British entomologist whose sad case was reported recently in the London Daily Mail. Mr. Ephinstone Forest Gilmour of Shepherd's Bush, said by the Daily Mail to be a member of the Royal So- ciety of Entomologists, found himself before a West London magistrate. Piled about in the court room were boxes con- taining hundreds of beetles — the physical evidence in the case. The result of the litigation was that the defendant received a sentence of three months for stealing beetles from the Natural History Museum in South Kensington. The prosecution said that Mr. Gilmour had held a student's pass to the museum for two years. He was first suspected when the authorities read an article by him in an entomological maga- zine. In it he mentioned having in his collection a species of Ix, '49] ENTOMOLOGICAL NEWS 157 beetle which the museum staff thought was unique in their own collection. Presumably this specimen was found to be missing, for Mr. Gilmour was placed under observation. He was soon intercepted leaving the museum with 55 speci- mens. He said he was only borrowing them, but the court took a different view of the matter. The home of the defendant was then visited by Detective Inspector Jeffery, and 5,141 beetles were found which were identified as the property of the museum. The moral of this episode might well be, that unrestrained enthusiasm may have dire consequences. — M.E.P. Reviews ANT HILL ODYSSEY. By William M. Mann. 338 pp., illus. Atlantic-Little, Brown. Boston. 1948. Price : $3.50. The present volume gives an account of Mann's boyhood and early manhood up until the time he took a position in the U. S. Government Service. Ordinarily such an account would in- terest only a small group of specialized readers, but this book has such a wealth of charm and wit that almost anyone, scientist or layman, who reads the first few pages will feel compelled to read on to the end of the book. Few naturalists, yes, even few sol- diers of fortune, can look back on a more colorful life. Kind and generous, Mann has always had an unusual ability to get along with literally all kinds of people from primitive head hunters to erudite and world-renowned scientists. This understanding of human nature showed up in his early boyhood days in Montana, which, in many respects, are reminiscent of Tom Sawyer. Mann's autobiography is literally one long collecting trip which was fortunately not too frequently interrupted and which ultimately reached out to many of the out-of-the-way places of the world. While still a very small boy in Montana he began collecting toads. Later, and in various parts of the United States, he collected insects, snakes and just about any other kind of animal that one can call to mind. There was, of course, the problem of preserving all of these specimens. Young Mann's solution to the problem in the case of the insects before he knew about pins was as follows : "I "invented a process of putting corks from small bottles in the bottom of a cigar box and sticking them with chewing gum ; to these I fastened my insect specimens, also with chewing gum (later I used glue), and during the spring made a small but to me fascinating collection." As time went on he learned about pins, but there were still many questions about the identity of the numerous specimens which were con- 158 ENTOMOLOGICAL NEWS [June, '49 stantly being collected. Thus the need of further education be- came apparent. The following quotation regarding the selection of a college shows Dr. Mann's delightful wit, which is apparent in his conversations as well as in his writing: "It seemed to me that a year in entomology under a teacher would give me a bet- ter understanding of labial palpi, trochanters, and scutelli. A heavy correspondence followed, chiefly in regard to college catalogues, some of which were confusing, but I did learn that Harvard University was not in New Haven, Connecticut, where I had written. "Then came a copy of the magazine, The Canadian Entomolo- gist, and in it was an article entitled 'The Hypopygium of the Tipulidae.' I had to look up the words to see what they meant. The article had been written by Professor Rennie Wilbur Doane of the State College of Washington, and it seemed certain that anybody who could write an article with a title like that would be a good one to explain the things I wanted to know. His col- lege, at Pullman, was the one I selected, though I did not tell my mother the exact reason for going there rather than to some place nearer home." His formal education at Washington State College, at Stan- ford and later at Harvard under the famous William Morton Wheeler gave young Mann a broad basis for his later studies of the animals collected in Brazil. Haiti, Mexico, Arabia and vari- ous Pacific Islands, and fitted him admirably for his government work in entomology and in the Zoo. If there is any one group for which this intriguing book will have a special appeal, it is the myrmecologist and the student of myrmecophiles. For throughout the book, Dr. Mann has in- cluded many interesting accounts of his own special little ani- mals, the ants and their guests. For those already conversant with his many technical papers on this subject, new and inter- esting sidelights await them. For my part, I find only one thing wrong with the book : there is not enough of it. It is certainly to be hoped that Dr. Mann will write further about his many adventures, collecting trips, and friends not mentioned in the present volume. — M. W. WING. A CATALOGUE OF INSECTICIDES AND FUNGICIDES. VOLUME II : CHEMICAL FUNGICIDES AND PLANT INSECTICIDES. By Don- ald E. H. Frear. Pp. xii + 154, super roy. oct., Waltham, Mass. 1948: The Chronica Botanica Co.; New York City: Stechert-Hafner, Inc. Price: $5.50. Ix, '49] ENTOMOLOGICAL NEWS 159 The first part of this catalogue was devoted to chemical in- secticides (Ent. News, 59: 55). In the present volume. Dr. Frear presents a list of the chemical fungicides arranged, as were the chemical insecticides, in a code system that places com- pounds that are chemically related near each other in the list. Then follow shorter lists of condensation products, of plant product fungicides and of miscellaneous fungicides. The sec- ond half of this volume is taken up by the long list of plant in- secticides that have been tested, arranged alphabetically. The indexes include a reference and author index, a numerical pat- ent list and, finally, a complete alphabetical index of all the chemical compounds that are mentioned in both volumes. The book is embellished by a frontispiece of Millardet, the discoverer of Bordeaux mixture, and by a number of vignettes of insects and plants reproduced from old sources. We cannot but express our gratitude to the Chronica Botanica Co. for demonstrating that even such a book as this, filled as it is with long lists of dry data, by the selection of the right paper, type, format, by a very few vignettes and by careful make-up can be made to afford the user a degree of esthetic pleasure along with the scientific information. — R. G. SCHMIEDER. Current Entomological Literature COMPILED BY RAYMOND Q. BLISS AND R. G. SCHMIEDER. Under the above head it is intended to note papers received at the Academy of Natural Sciences of Philadelphia and the University of Pennsylvania, pertaining to the Entomology of the Americas (North and South), including Arachnida and Myriopoda. Articles irrele- vant to American entomology will not be noted; but contributions to anatomy, physiology and embryology of insects, however, whether relating to American or exotic species will be recorded. This list gives references of the year 1949 unless otherwise noted. Continued papers, with few exceptions, are recorded only at their first installment. For other records of general literature and for economic literature, see the Bibliog- raphy of Agriculture, Washington, and the Review of Applied Entomology, Series A, London. For records of papers on medical entomology see Review of Applied Entomology, Series B. NOTE: The figures within brackets [ ] refer to the journal in which the paper ap- peared, as numbered in the List of periodicals and serials published in our January and June issues. The number of the volume, and in some cases, the part, heft, &c. is followed by a colon (:). References to papers containing new forms or names not so stated in titles are followed by (*); if containing keys are followed by (k); papers pertaining ex- clusively to Neotropical species, and not so indicated in the title, have the symbol (S).

INC., Lancaster, Pa. ENTOMOLOGICAL NEWS VOL. LX JULY, 1949 No. 7 Additional Data Upon the Fleas of the Sagebrush Vole By C. ANDRESEN HUBBARD, Vanport College, Portland, Oregon Since publishing last month (Ent. News, June 1949, pp. 141- 144) on the fleas of the Sagebrush Vole in the State of Wash- ington, the writer has been fortunate in having Dr. C. W. Clan- ton of the Washington State Board of Health send him several new batches of fleas from west of the Columbia River, whereas previous parcels had been taken east of the River, and through his own efforts in the field in the vicinity where Oregon, Cali- fornia and Nevada meet he collected from this mouse in all three states. The writer's voles (Lagnrus curatatits) were taken in live traps baited with apple and oatmeal in gullies that had had streams in their bottoms earlier in the year. The gullies were in sagebrush plains. The voles were taken in the ratio of about 1 to 4 with the meadow mouse Microtus inontanus and on the latter's runs. This new study, then, gives a picture of the fleas of Lagurus from Washington, Oregon, California and Nevada. Throughout their range these desert meadow mice carry a Thrassis of their own which the writer described in last month's article as Thrassis gladiolis johnsoni. The writer can now re- port this flea off Lagurus ciimtatus pauperrimus (State of Washington Sagebrush Vole) on both the east and west side of the Columbia River which cuts the range of the mouse in two in the State of Washington. The records are from Davenport, Lincoln County, Washington, April, May and June, a large series. This is east of the Columbia River. And from Ellens- burg, Kitittas County, Washington, during June and early July (169) OCT 2 5 1949 170 ENTOMOLOGICAL NEWS [July, '49 a good series from west of the River. And off La-gurus cura- tatits intermedius (Intermediate Sagebrush Vole), 14 miles north of Fort Bidwell, Modoc County, California, 2 males, 3 females; 13 miles south Adel, Lake County, Oregon, 1 male, 2 females ; 49 Ranch, 4 miles west Vya, Washoe County, Nevada, 5 pair. These data answer the question raised by the writer last month of how a Thrassis gladiolis could appear in Washington. Lagurus has carried it from south to north, in the south the range of the mouse being in the same dry sagebrush plains as Citellus leucurus, the Antelope Ground Squirrel, which is the true host of the flea Thrassis gladiolis gladiolis in southern Ore- gon, Nevada and California. The writer has found no variation in Thrassis gladiolis john- soni in the range of the Sagebrush Vole. A flea of the genus Megabothris carried by these mice shows considerable variation, however. Several hundred specimens delivered to the writer by Dr. Clanton from east of the Columbia River in Washington showed no great variation. These the writer described last month as Megabothris clantoni. The writer finds that the related flea from Lagurus c. intermediiis is different and new and shall be called : Megabothris princei, a new species There are before the writer at this time the holotype male and allotype female and a short series of paratypes. The new flea lies between Megabothris abantis and M. clantoni. Male : Process of clasper as in abantis and clantoni. Finger with general shape of clantoni but with portion above shank rec- tangular rather than constricted apically as in clantoni. Arma- ture as in abantis, i.e., 3 spiniforms on posterior border, two short, plump ones above, long pointed one below ; the lower shorter one closer to the long one. VIII sternite in male similar to clantoni but armature consists of more stout curved bristles at apex and a constriction on lower border at about mid point. Female : Apical outline of VII sternite not easily separated from abantis and clantoni, consisting in the allotype of a single Ix, '49] ENTOMOLOGICAL NEWS 171 rounded upper lobe, the armature of 8 major bristles and a lesser number of minor ones to the anterior. Spermatheca characteristic for the abantis-clantoni series but in type finger- like appendix is flattened apically toward body. The male of the new flea is 2.75 mm. long, the female 2.25 mm. The type locality is the draw behind the 49 Ranch house (deserted) 4 miles west of Vya, Washoe County, NEVADA. The type host is Lagitrus cnratatits intenncdiits (Taylor). The types, mounted on separate slides, bearing the writer's number 2712 are deposited in the National Museum. Paratypes are de- posited in British Museum, Canadian National Museum, Acad- emy of Natural Sciences of Philadelphia and California Acad- emy of Science. This flea bears the name of Frank Prince, Entomologist at Plague Suppressive Measures Laboratory, San Francisco, California. Records: Off Lagitrus cnratatits intermedius (Taylor), 49 Ranch, 4 miles west Vya, Washoe County, Nevada. Types and 3 males and 5 females; 14 miles north Fort Bidwell, Modoc County, CALIFORNIA, 2 males, 1 female; 13 miles south Adel, Lake County, Oregon, 1 male, 2 females. Off Microtns montanns micropus Hall, 49 Ranch, Vya, Ne- vada, a male. During mid-summer Dr. Clanton changed his field of opera- tions from east of the Columbia River in central Washington to west of the River. When the writer examined the fleas sent him off Lagurus from west of the River no variation was found in Thrassis gladiolis johnsoni but the Megabothris was different from the form east of the River. The new variation shall be called : Megabothris clantoni johnsoni, a new subspecies There are before the writer at this time the holotype male, the allotype female and 5 pairs of paratypes. In the new sub- species the finger is like clantoni but the VIII sternite is like princei and, since siphonapterists have given more weight to the finger than the VIII sternite in taxonomic studies, johnsoni is closest to clantoni. 172 ENTOMOLOGICAL NEWS u* '49 Male : Finger ham shaped as in both clantoni and princei but, as in clantoni, constricted at the apex. Armature as in clantoni, on posterior border below the characteristic long pointed spini- form, above it a short plump spiniform and at apical angle a short stout bristle, which in a small percentage of cases is spini- form. The VIII sternite is princei-like in that apically it is armed with a series of curved long bristles followed proximally by a series of short ones. Female: VII sternite as in the clantoni-princei-abantis series, with rounded upper lobe in allotype, the armature consisting of about 7 major bristles, 4 medium ones and as many small ones. Spermatheca typical for the group. This flea is smaller than clantoni and princei measuring only about 2.00 mm. in both sexes. The type locality is 18 miles east of Ellensburg, Kitittas County, WASHINGTON where Dr. Clan- ton took the fleas off Lagurus curatatus pauperrimiis, the type host. The holotype male and allotype female are mounted on one slide bearing the writer's number 2759 and deposited in the National Museum ; paratypes distributed as for M. princei. This flea bears the name of Dr. Murray Johnson, Surgeon, of Tacoma, Washington, one of the leading naturalists of the State. From this report it seems likely that the Columbia River is the dividing line between the range of M. c. clantoni to the east and M. c. johnsoni to the west. OTHER FLEAS FROM LAGURUS Two interesting records from Dr. Clanton's material from west of the Columbia River are from one vial of fleas off La- gurus : 48 males, 90 females of Meringis shannoni (Pocket Mouse flea) with only 5 pairs of Thrassis gladiolis johnsoni and 1 male Megabothris clantoni johnsoni. A second vial contained 6 pairs Megabothris c. johnsoni, 10 pairs Tlirassis g. johnsoni, a pair Catallagia dccipiens, 1 male Meringis shannoni. The writer took off Lagurus c. intcrmedius besides Thrassis g. john- soni and Megabothris princei, Malaracus tclchinnni and Catal- lagia decipiens. Ix, '49] ENTOMOLOGICAL NEWS 173 a a a •a a e Vj .S •ftk. '-0 ' o -a o 05 o 174 ENTOMOLOGICAL NEWS u* '49 In closing this article the writer wishes to say that the voles taken by him were brought back to the laboratory alive. It is now 2 P.M. and they have just ventured out of their nests for afternoon feed and exercise. The mice are gray, lacking the red found on the back of Microtus and their tails are very short, less than an inch in the mature mouse. As they feed, they go first to the apple. Apple then should be used as bait in live traps. Lagurus rises early for breakfast and at this time, coming from their warm nests, they carry many fleas. They soon dust them off, however, and catches later in the clay bring the collector few fleas. Fleas from Lagurus in Washington have been found plague positive but it is not known as yet which of the Laguran fleas are vectors, although Alalaraens telchinum has definitely been condemned as a vector. Because of the plague angle, Lagurus and its fleas should be handled with some caution. A Minute on Podium Luctuosum (Hymenoptera: Sphecidae) Ever since Frederick Smith described Podium Inctuosutn from North Carolina in 1856, this wasp has been a rather rare species. Kohl reported it from Texas in 1902, and in recent years a few specimens have been taken at or in the vicinity of Washington, D. C. A specimen of Podium hictnosuni was taken July, 1948 in a sand pit adjacent to Six Mile Creek, Ithaca, N. Y. This represents the northernmost record for the species up to the present. The specimen captured was a female carrying its prey, a female cockroach, Parcoblatta virginica (Brunner) [det. James A. G. Rehn]. Nothing has hitherto been known about the biology of Iiictiiosuin, although Rau presented a short but interesting account of the other Nearctic species, P. bigut- tatum. — V. S. L. PATE, Cornell University, Ithaca, N. Y. Ix, '49] ENTOMOLOGICAL NEWS 175 Notes on the Mating Behavior and Oviposition of Creophilus maxillosus (Linne) By GEORGE S. FIGHTER, Department of Zoology, Miami University, Oxford, Ohio Creophilus maxillosus is conspicuously larger than the ma- jority of beetles found around carrion. It can be distinguished easily from other beetles approximating its size by its Staphy- linid characteristic of abbreviated elytra. No other Staphy- linids of comparable size are found in such a habitat. Excluding the areas of whitish-yellow setae described below, the coloration of the beetles is entirely black. Since Creophilus ma.rillosus is attracted to carrion, small vertebrate carcasses were employed as lures. These were placed at various locations in the field and examined regularly in order to collect the beetles attracted there. Many different animals (fish, frogs, turtles, snakes, lizards, birds, mice, rats, cats, and rabbits) were utilized in the course of the experiment. All served equally well as lures for the beetles. Rats were used most commonly. The carcasses were generally placed directly on the surface of the ground. No attempt was made to trap the beetles at the car- rion since the carcasses were examined frequently and the pres- ence of an adequate food supply was sufficient to cause the beetles to linger. In addition, placing the carrion in containers and sinking the containers into the ground so that their brims are flush with the surface, which is the normal procedure for trap- ping, reduces its accessibility. When the carrion is completely exposed, there is nothing to hinder the natural dissemination of its odor and, hence, its discovery is facilitated. MATING BEHAVIOR In the laboratory the adult beetles were kept in a glass ter- rarium (35 X 15 X 12 centimeters) in which the dirt level was maintained at four to five centimeters. The beetles copulated readily under laboratory conditions, and the act was also ob- 176 ENTOMOLOGICAL NEWS u. '49 served on numerous occasions in the field. The following is a composite description of the observations noted. When two beetles approached each other for the first time, they brought their antennae and mouth parts into contact momentarily, brushing them against each other rapidly. They generally fol- lowed this by examining the tips of their abdomens with their an- tennae. These preliminary activities apparently were a means of sex identification. For if the two beetles were of the same sex, they snapped viciously at one another with their mandibles, disengaged themselves after a temporary struggle, and separated hurriedly. On the other hand, if the two beetles were of op- posite sexes, the male would immediately attempt to crawl astride the female. Frequently the female resisted such advances either by elevating the tip of her abdomen so that the male could not mount her or by running away rapidly. In either case the male at first persisted in its attempts. If the female ran, the male usually followed in close pursuit and sometimes succeeded in overtaking her. When the male's endeavors were continu- ally rejected, the copulation attempt was finally abandoned. When successful in mounting the female in the usual manner —crawling astride from the rear — the male bent the tip of its abdomen down to contact the slightly upturned tip of the female's abdomen and at the same time exserted its genitalia. At the insertion of the genitalia the male was astride the female. Its pro- thoracic legs were rested on the humeral angles of the female's elytra and were supported on their transversely expanded tarsites. The terminal tarsites, bearing the strongly curved claws, were pro- truded at the sides of the elytra and not employed in any manner of support. The mesothoracic legs were either rested on the edge of the abdominal segments or extended to the ground. Likewise, the metathoracic legs were stretched clown at the sides of the female to rest on the ground. This position of embrace characteristic of the initial stages of coitus wras never maintained over a long period of time. Some- times the female kept in continuous movement, and the union was accomplished as the beetles ran along, with the male jostled up and down in its awkward, insecure position. In most cases, Ix, '49] ENTOMOLOGICAL NEWS 177 however, the female remained motionless during the insertion of the genitalia but moved off after the elapse of a few seconds. Since the male had no firm clasp on the female with its tarsal claws and was attached to her only by its genitalia, the female glided from beneath the male easily in such cases, and the male became oriented so that it faced in the opposite direction to the female. The two remained united only by their genitalia. Unless the specimens were of similar size, the larger of the two usually crawled off. dragging its companion behind it. The smaller of the two seldom resisted or attempted to oppose the direction chosen by its mate. Both sexes were observed at- tacking and consuming maggots in many instances during coitus. Sometimes a second male attempted to copulate with a female already engaged. In such cases the two males snapped viciously at one another. An interference of that sort often resulted in the disengagement of the copulating pair. Then the stronger of the two males would engage the female again unless she man- aged to escape completely. The males were totally indifferent to one another in her absence. In the specimens confined to cages, the act of coitus was at- tempted almost every time a male chanced to encounter a fe- male, even though it was the same one with which the act had just been completed. The sexual impulse of the male was ap- parently stimulated at the slightest contact with a female. The duration of the act was brief, and the beetles normally disengaged themselves within three to five minutes. OVIPOSITION Eggs were deposited singly both above and below the surface of the ground. The dirt level was maintained at approximately five centimeters in the cages, and eggs were frequently found on the bottom as well as at various levels up to and on the sur- face. Likewise, eggs were found on the surface, beneath the carrion, and at various levels below the surface in the field. It seems likely from such discoveries that the beetles do not select particular depths of situations in which to place their eggs but are indiscriminate. 178 ENTOMOLOGICAL NEWS [Ju\y, '49 Although oviposition below the surface of the ground was never observed, it was seen on several occasions at the surface level. The female made no elaborate preparation of the sub- stratum to form a slit or cavity of any sort for the reception of the egg. She merely applied the tip of her abdomen to the sur- face and at the same time generally elevated the anterior portion of her body slightly by stiffening the fore and middle legs. The rigid condition of the abdomen frequently pushed its tip into the soil and produced a slight depression, but this seemed wholly dependent on the nature of the soil. The entire act required little more than a minute if the female were left undisturbed. Immediately after the egg was deposited, the female crawled away without examining the egg or attempting to conceal it. In several instances females in the process of ovipositing were accosted by males which attempted copulation. If the female had actually begun discharging the egg from her abdomen, such an interruption seemed to accelerate her activity. On the other hand, if she had just assumed her position, she tried to ward the male off in the usual fashion by fighting or running away hurriedly. In the latter instances the act was usually completed in a more secluded section of the cage. Despite the apparent haphazard placement of the eggs, it should be noted that they are, nevertheless, advantageously lo- cated. The congregation of adult beetles about carrion brings together large numbers of males and females, and the associa- tion naturally results in mating and oviposition at that site. Eggs deposited in such surroundings are incubated by the heat of the decay, and the newly emerged larvae have little distance to travel in locating supply of food. Ix, '49] ENTOMOLOGICAL NEWS 179 Eusattus vs. Sphaeriontis By IRA LA RIVERS, University of Nevada, Reno In 1908, Col. T. L. Casey described the genus Sphaeriontis to include "five known species," which he arranged in a key : 5". muricata (Le Conte) 1852, S. dilatata (Le Conte) 1852, S. acomana n. sp., 6". ciliata (Horn) 1894 and 5". puberula (Le Conte) 1854. He further emphasized that 5. dilitata could not be considered a synonym of S. muricata, as Horn had indicated as early as his 1870 monograph on the family. Having had occasion to go over Eusattus and Sphaeriontis somewhat completely in the recent past, it became rather obvi- ous that the group as defined by Casey was more finely drawn than the actual specimens themselves warranted. My conclu- sions are that Spliacriontis is a weak subgenus of Eusattus, and perfect intergradation between Eusattus muricatus and E. dila- tatus in my series indicates that Horn was correct in synony- mizing the latter with the former. Casey makes mention of the "densely punctulate epipleurae and more or less confluent granules of the elytra" as "amply distinguishing it" (dUatatus) "from muricata, aside from its radically different habitat." The morphologic structures he calls attention to are those which Horn long ago fully demon- strated to be too weak and intergrading to be of value, and it is difficult to see why Casey resurrected them. As for their being "radically different" in habitat, my experience has shown that the two occur in identical situations, on sand dunes or in sanded areas ; perhaps Casey's biologic information was based on sec- ond-hand data from others or gleaned from collecting one or a few anomalous individuals "out of character." Another possible source of error may have been the fact that Casey based some of his conclusions as to relationships within the group solely on published descriptions not having seen, at the time of his paper, specimens of E. dilatatus, E. pubcrulus or E. ciliatus. In addition, the three species Casey added to the genus are quite patently synonyms of Eusattus muricatus, my conclusions being based on specimens from his type locality. 180 ENTOMOLOGICAL NEWS [July, '49 The synonymy should be indicated as Eusattus Le Conte 1852 (S phaeriontis Casey 1908) muricatus Le Conte 1852 (dilatatus Le Conte 1852) (acotnana Casey 1908) (latissima (Casey) 1924) (julvesccns (Casey) 1924) ciliatus Horn 1894 puberulus Le Conte 1854 I have previously made passing mention of Sphaeriontis as a subgenus of Eusattus (1948: 709).

Wash., 40: 3, 1938), in his synopsis of the order Zoraptera, estimated the range of Zoro- typus hubbardi Caudell to be from Maryland to Texas. Al- though he included no records from Georgia, Alabama, and Mississippi, Guerney stated that the insect is probably abundant in all of the southern states. Recent collections from Alabama have been numerous enough to indicate that this is true at least in this state. Typical Z. hubbardi was collected from March 30 through April 28, 1949, in the following widely distributed lo- calities : Millport, Lamar Co. ; Gordo, Pickens Co. ; Alberta City, Peterson, and Lynn Haven, Tuscaloosa Co. ; Eutaw, Greene Co. ; Alabama Port, Mobile Co. ; Bear Point, near Orange Beach, Baldwin Co. ; and Chattahoocb.ee State Park, Houston Ix, '49] ENTOMOLOGICAL NEWS 181 Co. Specimens were identified principally on the basis of geni- talic slides compared with Guerney's figures. In seven of the localities, the insects were found under thick hark of moist pine stumps and logs. At Eutaw, they occurred under the bark of thoroughly dry pine stumps ; and at Peterson, they were under the bark of a moist oak log. Many insects, particularly termites of the genus Reticulitermes and ants of the genus Proceratluni, were frequently observed in the same situation as Zorotypus, but no evidence was found to indicate an obligatory association. In a total of 151 individuals taken, there were 59 apterous males, 45 apterous females, 3 clealate females, and 44 nymphs. No alate-form males were collected. Individual collections varied from a single apterous female to a group consisting of 21 ap- terous males, 18 apterous females, and 10 nymphs. Notes on Gesomyrmex (Hymenoptera: Formicidae) After my manuscript on Gesomyrmex (Amer. Ent. Soc. Amer. XLII (1949) : 71-76) went into proof, I received a communica- tion from Dr. James Chapman, Silliman University, Dumaguete. Philippines, together with workers from two nests of G. hizo- tiensis var. chapman i Wheeler. I feel that some of the data ex- tracted from the letter are well worth noting in print. When Dr. Chapman returned to Dumaguete about two years ago he began looking for colonies of Gesovnyrinex. A tree in which he had previously located several nests had been destroyed by fire when the Japanese burned his mountain house. Dr. Chapman looked for nearly two years before he found another colony. He had to climb trees, search for workers among the higher foliage, and then follow the ants back to their burrows in the branches. The nests are only in the living branches. Dr. Chapman states that he has taken Gesomyrmex on three different islands of the Philippines group and that the ants seem at least superficially to belong to the same species. A. C. COLE, Department of Zoology and Entomology, University of Tennessee, Knoxville 182 ENTOMOLOGICAL NEWS [July> '49 Night Collections of Dragonflies (Odonata: Anisoptera) By GEORGE H. BICK, Zoology Department, Tulane University, New Orleans My attention was called to the possibility of obtaining large numbers of dragonflies at night by Mr. J. Bolley and Mr. C. Chancy who observed many of them perched on weeds and shrubs and apparently sleeping in a weedy field just outside the city limits of New Orleans. On the night of May 4 Mr. Bolley and I collected Libellula ncedhami (9 males, 11 females) and Pachidiplax longipennis (1 male, 2 females) in about one and one-half hours using a flashlight only. Most of the dragonflies were taken about 18 inches above ground perched on the basal dry parts of Paspalum sp. On the night of May 24 at the same locality and in about the same period of time Dr. Penn and I collected L. ncedhami (11 males, 7 females), Anax jiimns (1 male), P. longipennis (1 female). These were taken along a road bordering the field and were mostly from Ambrosia sp., Verbena bonariensis, and Sali.v nigra at heights of about three feet. On both occasions the dragonflies were perched vertically and were apparently sleeping. They were taken in the beam of light with the fingers. Often they scarcely stirred even after capture. The ease in collecting these specimens as contrasted with the more tedious daytime net technique warrants calling it to the attention of other workers. The method seems to have possi- bilities to furnish basic data for population analyses. Ix, '49] ENTOMOLOGICAL NEWS 183 D.D.T. as a Contributing Factor to the Increase of Trema- tode Diseases in Man and Other Animals. Under the title "Does destruction of water insects cause increase of Trematode disease?" Mr. J. Omer-Cooper has an article in the Entomologist's Monthly Magazine, of London, for June, 1949, in which he states : "In the Hluhlwe game reserve [Zululand] . . . there is a stream — a mere trickle of water at the time we visited it — with many pools in its bed, some of which are large and inhabited by fine specimens of crocodile. These crocodile pools and indeed all the pools in the game reserve have been sprayed by aeroplane many times with D.D.T. The waters had a curious dull dead look. Careful collecting showed that the D.D.T. had done its work well ; not so much as a mayfly or dragonfly nymph was caught. There were no beetles, but the stones were dotted everywhere with surprisingly large numbers of aquatic mollusca. On the road to Mkuzi there was a fine pond with lily pads over which ran . . . jacanas . . . while dragonflies darted here and there over its surface. Here was a plentiful supply of both dragonfly and mayfly nymphs. Beetles were present in numbers that made glad the heart. Molluscs were not particularly plentiful." Other examples of absence and of presence of dragonflies and their nymphs in Zululand and in the Northern Transvaal are given. Where enemies of molluscs, e. g., birds, certain insects, are destroyed, molluscs are numerous. "An increase in mol- luscs is likely to be accompanied by an increase in those Trema- todes which spend the early part of their lives within their bodies. Many of these trematodes are parasites of the Mam- malia. Man and his domestic animals sufifer from their attacks. When water snails increase there should be a greater incidence of Trematode disease. In Zululand and in the Transvaal, Bil- harziasis is very prevalent and seems to be definitely increasing." \Ve specify D.D.T. in this concatenation to render Mr. Omer- Cooper's examples the more eligible to inclusion in that series of classics which embraces Darwin's famous case of old maids (a post-Darwinian addition, to be sure), cats, mice, humble bees and red clover, and, still older.

Button and Co., Inc. Pp. xii, 727, 624 figs., $12.50. Reviews of earlier editions of this great textbook have ap- peared in ENTOMOLOGICAL NEWS for 1925 and 1934. Published by Methuen and Co., Ltd., London, it is handled in this country by E. P. Button and Co. who have placed it on sale as of May tenth. Its author, the well known chief of the Rothamstead Experimental Station, died on April third. Ix, '49] ENTOMOLOGICAL NEWS 195 The jacket of the book states that this is a "revised" edition, a statement that is rather misleading since the book has by no means been brought up to date and does not differ essentially from the third edition which appeared in 1934. A few unimpor- tant illustrations have been replaced since then and two or three new references have been added to the literature. In spite of the fact that some parts of the book are not up to date, this text is still very valuable and useful, even in America. The section on classification is very extensive and thorough and under each order there is included an account of the internal anatomy of that order, something that one cannot find in Ameri- can general textbooks. The information on external features, taxonomy and biology is similar to that in our own Comstock and about as detailed, while the keys are less formidable and discouraging since they are broken up into separate keys to the superfamilies. Finally, another useful feature of Imms has been the carefully selected list of references at the end of each chap- ter.— R. G. SCHMIEDER. THE FIG, by Ira J. Condit. Pp. xviii + 222, 27 text fig- ures. Waltham, Mass., 1947, the Chronica Botanica Co. ; New York City, Stechert-Hafner, Inc. Price $5.00. This volume is sufficiently comprehensive in its treatment to be valuable alike to the historian, the fig culturist, the botanist and the entomologist. The author has traced the history of the fig in great detail as the most ancient of known cultivated fruits, from about 2000 B.C., to its first introduction into America in about 1575, and on to its high development in the modern fruit industry. In addition, he discusses the systematic botany, breeding, caprification, varieties and character of the fruit, fig culture, propagation, dried figs, chemistry and food value, marketing, disease and pests. The work is of interest to the entomologist not only from the standpoint of insects which attack the fig, but also for their unique and necessary use in its fertilization. The book is most thoroughly documented and contains a comprehen- sive bibliography of about 750 titles. — M. E. PHILLIPS.

INC., Lancaster. Pa. ENTOMOLOGICAL NEWS VOL. LX OCTOBER, 1949 No. 8 Studies on the Silphidae. I. Secondary Sexual Differences in the Genus Nicrophorus (Coleoptera) By RAYMOND Q. BLISS, Philadelphia, Pa. Secondary sexual characters have been described in the genus Nicrophorus by Horn (1), Portevin (2), and Arnett (3), but there is some lack of agreement among these authors as to the characters included and as to the reliability of each character when used to diagnose the sex of an individual. My own re- cent studies have led me to conclude that there are no secondary sexual characters valid for the whole genus, although some spe- cies may show them. The above authors agree that the form of the anterior tarsi is a good character to separate the sexes. Horn states, "Tarsi slender, the anterior dilated in the male and fimbriate at the sides." Arnett states, ". . . the males have . . . the fore tarsal pulvilli expanded, whereas in the females . . . the fore tarsal pulvilli are simple." Portevin says, of the tribe Nicrophorini. page 178, "Les tarses sont de 5 articles, les quatre premiers larges chez le J1, aux tarses anterieurs," and on page 187, of his genus Necrocharis, "Celui-ci [males] a les tarses anterieurs faiblement dilates," and on page 191, of the genus Nicroplinrns s. s., "Les tarses anterieurs sont dilates chez le ^ sur les quatre premiers articles, parfois si faiblement qu'ils ne different guere de ceux de la $." This last statement seems to contradict some- what the first. The shape of the area of the head behind the eyes is used by Portevin who says, page 175, "Tete ovale. parfois subtriangu- (197) NOV 2 8 1949 198 ENTOMOLOGICAL NEWS |Oct., '49 laire ou carree en arriere, chez le J\ a cause clu developpement des tempes," and on page 186, Necrocharis, "Tete ovale, brus- quement etranglee derriere les yeux; . . . ," apparently with- out regard to sex, and on page 188, of the genus Nicrophorus s. s. "Tete grosse, ovale, $, subtriangulaire, J\, avec les tempes, tres renflees dans ce dernier sexe, . . . ." Arnett says, "the males have the eyes situated well forward on the head, ... in the females the eyes are placed well towards the back of the head, . . . ." Horn, however, says, "The head exhibits some variation in form within specific limits ; that is, while the eyes in some individuals are very close to the hind angles of the head, in others the head is notably prolonged behind them. This is neither sexual nor specific." The clypeus and rhinarium are also used : Portevin says, page 176. "La piece clypeal, generalement campanuliforme chez le J\ est presque toujours de la meme couleur dans les deux sexes, mais elle varie de forme et d'etendue avec la taille des individus ; elle est toujours plus ou moins reduite chez la 5-" and on page 188, "L'epistome est separe du front par une ligne tantot droit, tantot angulee ; la piece membraneuse qu'il renferme est gene- ralement plus developpee chez le J1 ; ou elle affecte la form campanulee ; elle s'etend alors presque toujours jusqu'a la suture clypeo-frontale. Chez la 5 elle a souvent une forme triangu- laire, passant au trapeze tres transverse, pour aboutir a une simple bordure etroite a la partie anterieure du clypeus ; elle est parfois si petite qu'on peut la considerer comme nulle. Sa couleur est constante dans la meme espece mais varie quelquefois avec le sexe." Arnett says, "... the <$<$ have . . . the clypeus large ... in the $ the clypeus is appreciably smaller. . . ." Horn also states that the rhinarium varies in size and shape but gives it no sexual significance. He does not give any differ- ence in the clypeus. Portevin states that the tooth on the posterior trochanter is always more developed in the male but varies with the size of the individual. He also says that the frontal lines of the head are more often less noticeable in back in the male and equally well marked from one end to the other in the female. He sums up as follows : "Les tarses anterieurs sont dilates chez le J* sur les quatre premiers articles, parfois si faiblement qu'ils ne dif- Ix, '49] ENTOMOLOGICAL NEWS 199 ferent guere de ceux de la $. Ce sont alors les caracteres tires des trochanters, de la forme de la tete et surtout de la membrane clypeale, qui indiqueront le sexe." He mentions one or all of these characters in his remarks on each species. In Portevin's remarks, in which he sometimes says clypeal piece and sometimes clypeal membrane, I find it difficult to decide whether he is referring to the entire clypeus or to the rhinarium. However, I found the rhinarium to be so variable individually that I believe it cannot be used at all. This seems to me to apply also to the frontal lines, and to some extent to the posttrochantinal spines. Horn says that the posterior femora are stout in the J1 of N. carolinns and Ar. americanns. I did not find this to hold good and noted that there is some variation in individuals. Horn also says that in N. orbicollis the posterior tibiae are much stouter in the J\ It seems to me that there is a tendency for them to be more slender proximally and more expanded distally in the J1 but this also does not hold for all individuals. How- ever as these characters are only given for the particular species and in this study I am only considering the secondary sexual characters for the genus they are not included in this paper. Recently I had the opportunity to study the material of this genus in the collection of The Reading Public Museum and Art Gallery, Reading, Pennsylvania. An attempt was made to evaluate the usefulness of these characters in determining the sexes, and to see if there are any secondary sexual characters that are possessed, in common, by all the species of this genus. This paper is the result of that study, and the remarks and con- clusions are based on the above mentioned material. The specimens were relaxed in Barber's relaxing fluid for from 24 to 48 hours and the genitalia drawn out, thus enabling the sex to be determined. They were studied under a Spencer stereo-binocular microscope using the 9 >: ocular and the 1 X, 2 X, and 3 X objectives. Tn each species those characters that seemed to be of any value in that species \vere studied and recorded. The data presented below are the results of my in on 288 individuals belonging to 12 species. 200 ENTOMOLOGICAL NEWS [Oct., '49 A7, carolinus (L.), 7 J^J1 and 7 $$ were studied. The fronto- clypeal suture is straight or nearly so in all. One male has the temples expanded, the rest small. One male has the fore tarsi less expanded than in the other males, and one female has the fore tarsi slightly expanded. As for the posttrochantinal spine, the male mentioned above with less expanded fore tarsi has small spines and is a small specimen. Another male has these spines small. Two females have these spines larger than the other females. It seems then that the fore tarsi are a fairly good indicator of sex in this species but not infallible. They are, in both sexes, less expanded than in most species of the genus. The posttrochantinal spine is not very good and the other characters worthless. N. americanns (Oliv.), 14 <$<$, 21 9$. Three males have the frontoclypeal suture straight or nearly so, and in one female it is slightly curved caudad. The other males have a larger clypeus and the frontoclypeal suture is curved caudad, the other females have this suture straight and a smaller clypeus. How- ever the difference between the sexes in these two characters is slight in some individuals. The temples tend to be larger in the males but this difference is slight also. One of the males with a straight frontoclypeal suture has small temples, and three females have the temples large. The fore tarsi are expanded in both sexes. The posttrochantinal spine is the same in both sexes. There seems to lie no very good secondary sexual dif- ference in this species. N. sayi Lap., 8 J'J1, 3 $$. The frontoclypeal suture tends to be curved caudad in the males and straight in the females. The temples are all small but tend to be smaller in the females. One male with a straight suture has very small temples. The others of each sex have these two characters more typical of their sex but the difference is slight. The fore tarsi of the males are ex- panded. One female has the fore tarsi slightly expanded, the other two not expanded. The posttrochantinal spine has no significance. The fore tarsi seem to be the best character but I do not like to draw conclusions from such a small number of specimens. Ix, '49] ENTOMOLOGICAL XEWS 201 .V. orhicollis Say. 34 £$, 24 $$. The f rontoclypeal suture is straight or almost so in both sexes. The temples tend to be larger in the male but five males have small temples. The fore tarsi are not a good secondary sexual character as they tend to vary in both sexes, in some females they are expanded and in a few males they are slender. The posttrochantinal spine also varies with the individual. The temples seem to be the best character but are not absolutely reliable. N, marginatus Fab., 37 ^J1, 29 $$. The frontoclypeal suture varies. The temples tend to be large in both sexes. The fore tarsi are expanded in the male and slender in the female. This held good for all the specimens. The posttrochantinal spine varies with the individual. The post tibia varies with the indi- vidual in the amount of curvature. The fore tarsi appear to be a very good criterion for determining the sexes. N. pushtlatus Herschel, 12^, 10$$. The fore tarsi are expanded in the males and slender in the females, except one female, a large individual, has them slightly expanded. The other characters vary with the individual. .V. investigator Zett., 5 J\^, 6 $$. The frontoclypeal suture is slightly curved caudad in the males and straight in the females. The temples of the males vary somewhat but are larger than the females. The fore tarsi are expanded in the males and slender in the females. The posttrochantinal spine varies but tends to be more prominent in the males. All the secondary sexual characters seem to be good, but I think definite conclu- sions should not be made on such a small amount of material. Ar. nigritus Mann.. 2^^, 5$$. This is too small a number for definite conclusions, but none of the characters is good in- sofar as shown by this material. N. vespilloidcs Hbst.. 6 <^ J\, 6$$. The small number pre- cludes any conclusions, but none of the secondary sexual char- acters hold good. N. toincntosus Web., 17 J'J1, 20 $$. The frontoclypeal suture is slightly curved in the males and straight in the females, the difference is slight and one male has a straight suture. The temples tend to be large and square in the males and small and 202 ENTOMOLOGICAL NEWS [Oct., '49 round in the females, but vary individually, and some of each are like the opposite sex. The fore tarsi are expanded in the males and slender in the females. The posttrochantinal spine varies individually. The fore tarsi seem to be the only reliable char- acter in this species. Af. (juthilus Mots., 5 J'J1, 5 5$. This is too small a number to draw conclusions. All have the frontoclypeal suture straight and the temples large. The fore tarsi are expanded in the males and slender in the females. N. Jiecate Bland, 2 <$£, 3 $$. Again the number is too small. However none of the secondary sexual characters was reliable except the fore tarsi which are expanded in the males and slender in the females. DISCUSSION It seems hardly necessary to point out that it is the function of taxonomy to describe species in such a way that they may be recognized and this should apply to the sexes also. If sec- ondary sexual differences exist they should be described, but this can only be determined from a study of a fairly large series of specimens. Differences that are found only in some species should not be given as applying to a whole genus. Characters that vary individually so that the individuals of each sex ap- proach those of the other sex are not useful even though the}- do not actually intergrade. Those characters that do not vary individually, but are possessed by some individuals of each sex. even though they may predominate in one sex and be rare in the other, are of no value. To describe such characters with such qualifying words as 'generally,' 'sometimes,' or 'more or less' is confusing. Even though the statement, as qualified, is true one cannot know the number of exceptions that exist. Any rule or character used diagnostically must hold good for almost all of the individuals, certainly at least 90 per cent, and even this pro- portion may be too small where accurate results are desired. My studies have convinced me that there are no secondary sexual character that are applicable to the entire genus. The fore tarsi seem to be most useful, but even this character does not hold good in some species. In those in which it does, it is Ix, '49 j ENTOMOLOGICAL NEWS 203 possible that if a larger number of individuals had been avail- able for study more variation might have been shown. As to the other characters, N. investigator is the only one in which they hold good, but 5 J'J1 and 6 $$ cannot be used as an ade- quate sample of a species. The shape of the temples is almost always either definitely rounded or square without intergrades but cannot be correlated with the sex in many individuals. The fronto-clypeal suture varies individually and intergrades, and so does the rhinarium. The posttrochantinal spine intergrades be- tween the individuals of each sex in each species. It does seem to show specific differences in some species but that is apart from the subject of this paper. Many of the individuals show a strong tendency to have the characters that have been said to pertain to the opposite sex. This is more true of some species than of others, and especially the smaller males of each species approach the female and the larger females approach the male in the characters studied. Some individuals resemble the op- posite sex in only one of these characters while others do in two or three. The use of the term "gynandromorph" in this connection is incorrect, according to modern usage, since no true sex-mosaics were encountered, i.e., no individuals in which a definitely circumscribed region, say one side, is genetically of the opposite sex. It seems, then, that to determine the sex the genitalia must be observed. They can be drawn out after being relaxed, or caused to be extruded by the method of Valentine (4). though I have not tried the latter. Some individuals die with the genitalia sufficiently extruded to determine the sex. Also the males have what appears to be one more abdominal segment than the female.1 This is more or less retracted into the next segment cephalad, but is frequently extruded enough to be ob- 1 I am not concerned here with the homologies, but only with determin- ing the sexes. However, from a rather cursory study of the literature I am inclined to the opinion that, in this genus, the first two abdominal sternites have become atrophied and that the six visible ventral abdominal sternites are really sternites 3-8 of the abdomen, and that the extra seg- ment of the male mentioned here is the 9th. Also that in the female tin: ninth segment, or part of it, lias participated in formin.u the genitalia. 204 KNTOMOLOGICAL NEWS [Oct., '49 served. It is composed of four sclerotized pieces, one dorsal, one ventral, the other two lateral, connected by membranes. The aedeagus when extruded comes out between the ventral and left lateral pieces, where the membrane is reduced. I would have liked to have made a more precise and quantita- tive study of this subject but rather doubt that any additional practical information would have come of it. I believe I have shown that the usually used sexual differences are not very reliable, so I have cleared up this one point. A more thorough study, if undertaken, should deal with each species separately, using a large series of specimens.

This attractive little book makes fascinating and easy reading. The result of five years of patient study and experimentation by a retired professor of physiology, it is dedicated to "Crumple- Wing," a perfect female of the large species Sceliphron ccincn- tariuui, perfect except that one wing failed to expand fully so that she could not fly. "Crumple-Wing" therefore had to be attended by the author. In this task much was learned that had not been known before, how the mother mud dauber, herself, feeds on the vital body fluids of spiders as well as stocking her cells with their paralyzed bodies for her offspring. Mud daubers are shown to have personality, to differ from each other in their reactions. By patient efforts they may be conditioned so that they will feed on honey placed on one's finger. Life histories of mud daubers are given and these are illustrated by plates of photographs including kodachrome re- productions of the wasps and spiders in addition to very help- ful figures in the text. Much attention is given to the white pellets seen in the "fat body" of the overwintering larva and to those passed from the rectum of the adult into the cocoon before emergence. These are largely made up of uric acid, highly insoluble in water. How, then, is this waste product so quickly transferred from the tissues where it is stored to the rectum whence it may be voided ? It is shown that by means of the enzyme uricase the "uric acid to allantoin" reaction takes place in the body. This soluble allantoin, as also some uricase, is excreted by the Malpighian tubules into the rectum. Then, with the reabsorption of excess water, the allantoin in the rectum becomes highly concentrated, resulting in a reverse reaction, "allantoin to uric acid," which is also initiated and maintained by the uricase. Thus the pellets reappear where they may be voided. "What man, afflicted with gout, would not envy the mud dauber her ability to eliminate uric acid when she is ready to emerge from her cell ?"- — P.

This review was prepared under the auspices of the Entomol- ogy subcommittee of the above Coordination Center. Dr. Roger B. Friend, of the Connecticut Agricultural Station, is the chair- man. The substances treated of are : nicotine, pyrethrum, rote- none, organic thiocyanates, dinitrophenols, phenothyazine, DDT, benzene hexachloride and organic phosphates. In respect to each of these substances a concise account is given of the infor- mation gleaned from the literature on : its toxicology, method of gaining entrance to the body of the insect, the physiology of its action (i.e., upon what tissues or organs it acts and the mode of action), and some other matters of biochemical interest that were available. The information recorded is in all cases cred- ited to the original sources, which are listed in the 300 selected references at the end of the book. To workers in this field, this little book will, no doubt, be a great convenience. To the non-adept, it will at least provide some acquaintance with the difficulty and intricacy of the prob- lems involved and yield some insight into the type of work presently occupying insect physiologists and toxicologists.— R. G. SCHMIEDER. Ix, '49] ENTOMOLOGICAL NEWS 223 Entomon, a new Journal. Entomon. Internationale Zeitschrift fur die gesammte Insek- tenkunde. The extended title includes also : "vereinigt mit Zentralblatt fur das Gesammtgebiet der Entomologie, Klagen- furt." This journal has appeared monthly since January 1949. The size is 6VL> x 9 inches, and each number consists of 24 pages of text, double column, and using small type, ca. 8 point. It is published in Munich by Dr. Herbert Brandt and Hermann Bollow, and there are listed on the masthead as contributors 17 outstanding entomologists, mostly European. It is planned to publish on all aspects of the science and to interest all kinds of entomologists with a view of offsetting the effects of too narrow specialization. In the first issue there is an article, by Hans Sachtleben, Director of the deutsches entomologisches Institut, on the prob- lems of bibliography. This institute is planning to bring the bibliographic works of Hagen and of Horn and Schenkling up to date; these older works include 25,229 titles up to 1863. W. Horn estimated that about 300,000 titles have appeared between 1863 and 1925. Since 1925 there have been annual increments of about 5000, and the total number of titles since 1864 must be around 400,000, of which almost three-quarters (280,000) have been accumulated in the card files of the Insti- tute. The Institute solicits the aid of all entomologists and institutions in completing this work and in checking the cards to make corrections and additions to the parts dealing with their own publications. Published, this index, since 1864, would occupy 20 volumes of 1000 pages each. The Horn and Schenk- ling "Index," unlike the Hagen work, is still without a subject index, a lack that may be remedied as a result of work now well under way by the coleopterist Dr. Carl Fiedler. Dr. Fiedler, now 85 years of age, is known, among other things, for his papers on American Cryptorrhynchidae. Also in this first issue are : an account, with seven small maps, of the spread of the San Jose scale over the face of the earth, a description of the external anatomy of the Narcissus fly Lam- petia, as well as special departments for International Nomen- clature, Entomological Technic, Short Notes and Reviews. The other early issues have the same make-up and in each there are articles of general interest as well as specialized systematic papers. There are articles on stridulation in grasshoppers, but- terfly migrations, quantitative zoogeography, and there is one giving new data on the amazing mating blights of male bumble bees. These males, it appears, cover a 300 meter circuit with its many regular stopping places about 20 times per hour all day long ! Lazy drones ?

THE LANCASTER PRESS, INC., Lancaster. Pa. ENTOMOLOGICAL NEWS VOL. LX NOVEMBER, 1949 No. 9 Some Unusual Syrphid Flies By FRANK M. HULL, University of Mississippi Several flies of unusual interest that have been recently re- ceived are here described. Cacoceria willistoni n. sp. A remarkable fissicorn fly differing from cressoni Hull in the black stripe along the second vein besides numerous other par- ticulars. Length 10.5 mm. Male. Head: vertex black, slightly raised; the ocelli lie in an equilateral triangle, the anterior part of the vertex quite pollinose with scattered whitish hairs, the posterior pile of the vertex somewhat more yellowish. The eyes are dichoptic, separated by a distance at least as wide as the total width of the ocellar triangle, and the front diverges sharply beyond this medial point. Across the medial point of the front there is a slender crease which is bare ; the white micropubescence reaches above and below up to this bare crease. Most of the lower front, however, is polished and bare and the pubescence end.s along the eye margin opposite the preantennal callosity and begins again just below the antennae where it curves downward and mediahvard to reach across the face below the antennae. There is also a broad band of sparse, whitish micropubescence which extends diagonally down from the eye margin to the epistoma. The face, metallic black in color, has a low incon- spicuous tubercle in the middle, is faintly pollinose in the middle. Eyes bare. The antennae are slender and elongate, longer than the height of the head, and the third segment is (225) JAN 2 4 1950 226 ENTOMOLOGICAL NEWS [Nov., '49 quite remarkable. It is developed into two long, deep, slender prongs ; the dorsal prong is not quite as long as the ventral one and is slightly curved downward. This prong bears the long slender whip-like arista which is slightly and gradually thickened over the basal half and becomes quite fine at the apex. The first segment of the antennae is slender and elongate and five or six times as long as wide, pale brownish yellow on the basal half, becoming diffusely blackish apically and is consider- ably longer than the slender second segment which is entirely black. The third segment is entirely black and the arista dark- brown. There are no traces of pores upon the third segment. Thorax: mesonotum dull black, rather convex, with a pair of widely separated, vittate stripes of yellow pile which is nearly erect but directed slightly forward. These stripes merge into a broad wide area of similar pile in front of the scutellum which is bordered on either side by short thick black pile. All of the pile on the sides of mesonotum behind the suture is black except for this middle area and except for a slender band of incon- spicuous yellow hairs merging with the black which lies im- mediately behind the transverse suture. There are two or three scattered yellow hairs in the middle of the black pilose area and the pile of the post-calli is mostly black with a few yellow hairs. The pile in front of the suture is entirely brassy yellow but is subappressed and pointed backwards except upon the wide submedial stripes as previously described. Pleura dully shining black with whitish pile, the scutellum dark brassy brown, almost black with the margin obscurely and narrowly yellowish brown. The pile is short and yellow and there is a we'll developed yellow ventral fringe. Squamae and fringe blackish. Halteres yellowish white with a black knob. Leys: anterior and middle legs dark sepia-brown, the hind legs also dark sepia-brown except that the hind femora are narrowly but obscurely and diffusely pale yellow upon the attenuate por- tion at the base. As in the genotype, the femora are very much thickened and quite wide in the middle but gradually taper to the narrow apical and basal ends ; the base is especially nar- rowed and spindle-shaped. Pile of hind femora whitish and Lx, '49] ENTOMOLOGICAL NEWS 227 there are five slender, ventral, apical, widely spaced, sharp hlack setae. Hind tibiae quite arcuate and flattened with a sharp apical spur. Wings: hyaline with a distinct hut diffuse, smoky blackish border along both sides of the second vein, from the point of origin of the vein in the middle of the wing, nearly to its junction with the costa. The anterior apical portion of the marginal cell is left clear ; the pterostigma is entirely deep sepia-brown. Abdomen: subpetiolate in shape and chiefly dull black in color. The first segment is shining black, obscurely yellowish brown in the middle and the segment narrows con- siderably posteriorly and the second segment continues the constriction of the abdomen for a short distance and then begins to gradually expand so that the posterior end of the second segment is distinctly wider than the base of this segment. The second segment is narrowly and obscurely brownish yellow along the base but this color does not reach the sides. Im- mediately behind the yellow color the abdomen is nearly opaque black and this opaque black is gradually replaced by faintly shining bluish or greenish black. Third segment slightly wider posteriorly than basally and this segment is about as long as wide, its color faintly shining greenish to brassy black. Fourth segment together with the hypopygium forming a wide convex club-shaped arrangement. It is. however, not wider than the third segment ; its pile is entirely short, appressed and yellow. All of the pile of the third segment is appressed and yellow except for a small area in the middle of the' segment on the posterior half where the pile is blackish. The pile of the second segment is entirely black except for the long fine scattered hairs on the lateral margin. Pile of first segment whittish. long and fine upon the sides. Female. Similar to the male in every respect except that the third antennal segment is not fissiform. The third segment is. however, quite long and slender and seems to be at least as lou»- as the lower branch of the male. The abdomen is similar o except that the second segment is not quite as much constricted basally. 228 ENTOMOLOGICAL NEWS [ Nov., '49 Holotype: male, Chanchamayo, PERU, August 16, 1948, J. Schunke ; allotypc: female with the same data. In the author's collection. In 1930 the author erected the genus Cacomyia with cressoni, from Mexico, as genotype, from a female specimen in which the third antennal segment was broken away at the base. The genus was based upon the peculiarities of the face, abdomen and hind femora. The name was changed by the author in 1936 to Cacoceria as the name Cacomyia was found to be preoccupied. To the generic characterization of the genus then we now must add that the males are dichoptic and the third antennal segment deeply fissicorn in this sex. Mesogramma rhea n. sp. Related to hieroglyphica Schiner. This pretty species is dis- tinguished by the polished black abdomen in which the sides are narrowly light yellow, for most of the basal length of each seg- ment and there is a distinct, opaque, elongate, wedge-like black spot in the middle of the second, third and fourth segments. Length 6 mm. Male. Head: face and front light yellow, the face short, the narrow cheeks blackish, the scant pile white except opposite the antennae where it is blackish. Lower sides of the face with a large triangle of white pubescence. Antennae reddish brown, paler ventrally except upon the outer two-thirds of the third segment. Arista blackish. Vertex violaceous with blackish pile. Occiput black with metallic reflection and greyish white pollen and pile, the latter but slightly flattened. Tlwra.v: me- sonotum metallic black with sharply denned shining blue medial stripe overlaid by faint grey pollen. The humeri are pale yellow, the notopleura and remainder of the lateral margin metallic blackish. Scutellum brassy black, the posterior margin yellow, the yellow not extending to the base. Pile of mesono- tum fine and yellow ; scutellar pile of the same color and longer with five or six long, black hairs on the margin ; the posterior half of the mesopleura and a large spot on the upper sterno- Ix, '49 1 ENTOMOLOGICAL NEWS 229 pleura yellow, the remainder of the pleura shining black, in places with brassy reflections. Squamae yellowish white, the halteres reddish orange. Legs: anterior femora yellow with wide, diffuse, subapical band, their tibiae pale yellow with a brown spot in the middle ventrally and their tarsi brown. Middle femora yellow with still wider subapical brown annulus and with a subbasal, dorsal, brown spot. The yellow tibiae are faintly brownish just beyond the middle, the base of the basitarsi yellowish and the remainder brown. Hind femora pale yellow on the basal third, narrowly at the apex, but widely shining black between. These femora a little thickened. The hind tibiae are entirely black except quite narrowly at the base, the tarsi entirely blackish sepia. Wings: hyaline, pterostigma pale brown, the alulae narrow but wider than the basal section of the costal cell. Abdomen: slender, slightly increasing in width to the end of the fourth segment, the first segment shining black except linearly along the lateral anterior margin and with a medial, opaque black vitta and there is a narrow, yellow vitta or stripe lying upon the lateral margin reaching neither the base nor the apex. Third segment shining black with opaque black medial vitta and with more prominent, sharply marked, yellow lateral stripe which runs from the base two-thirds the length of the segment. Fourth segment in every way similar to the third. Fifth segment similar but shorter, the lateral yellow stripe not quite so large and the opaque medial spot absent. Hypopygium shining black apically but otherwise yellowish brown. Female. Similar to the male, the middle of the front metal- lic black, the face faintly brownish in the middle, the abdomen a little wider and faintly oval with the same pattern of yellow spots and opaque medial vitta. Fifth segment with an oval, opaque black spot in the middle. Cotvpes as follows: 3 males, Nova Teutonia. BRAZIL. Frit/. Plaumann. one female. >ame data. 230 ENTOMOLOGICAL NEWS [Nov., '49 Baccha lucretia n. sp. A dark sepia blackish species with yellow face and four slender yellow vittae upon the third, fourth and fifth segments of the abdomen. Related to notata Loew. Length 8 mm. Male. Head: the vertex dully shining black with a single row of black hairs. The front is pale yellow upon the sides with the yellow margins meeting at the junction of the eyes and with a large, black, faintly shining triangle in the middle of the front which anteriorly rests upon the large yellowish pre- antennal callosity and emits short, lateral, arms enclosing the upper portion of the callosity. In the center of the callosity is a large, shining black, anteriorly angular, posteriorly rounded, black or purplish black spot. The face is pale yellow with a reddish brown wedge medially reaching from the center of the tubercle up to the base of the antennae. Cheeks pale yellow tinged with brown in the middle. Pile of face white and of the front black. The first and second segments of the antennae are pale yellowish brown ; the third segment is brownish orange below, blackish above, narrowly towards the base and widely towards the apex. Arista narrowly reddish at the base and blackish upon the remainder. Occiput grayish yellow pollinose with a single row of fine, non-flattened, yellow hairs. TJioro.r: mesonotum brassy black with the lateral margins narrowly but continuously pale yellow including the humeri and the post calli. Middle of mesonotum with a pair of widely separated, relatively narrow, light reddish brown pollinose vittae which become evanescent one-fourth of the length of the mesonotum measured from the scutellum. The scutellum is light yellow with the disc becoming brownish, which is more evident when viewed from the side. The pile upon the surface of the scutel- lum is very fine, scantv and comparatively short. T can find no evidence of ventral fringe hairs. Mesonotal pile also short, scanty and pale brownish or reddish in color. There is no anterior collar. The pleura are metallic black with the pro- pleura, the posterior margin of the mesopleura and a spot upon the upper sternopleura yellow. Halteres sepia, squamae with border and fringe also dark sepia. Lcf/s: anterior pair en- Ix, '49] ENTOMOLOGICAL NKWS 231 tirely light yellow ; the middle legs are the same color except that their femora tend to be pale brown subbasally. The hind femora, their tibiae and the basal two-thirds of the hind basi tarsi are dark sepia brown. Viewed in some lights, the hind femora in some individuals are a little lighter than their respec- tive tibiae but have a wide, blackish, subapical annulus. The remainder of the hind tarsi are pale brownish orange or yellow. II 'ings: moderately wide and wholly and uniformly dark sepia- brown. The alulae are quite slender and only at the apex are they wider than the basal section of the costal cell. Preanal spuria faint. Third vein straight but very slightly carried down at the apex of the wing by the costa. Subapical cross vein gently sigmoid, the lower ends of subapical and lower cross veins each with well developed spur. Anal vein quite straight. Abdomen: slightly spatulate and deep sepia-brown, almost black, with conspicuous, sharply defined, light yellow vittae. The first segment is yellow on the sides and brownish black in the middle, especially posteriorly. Anteriorly the lateral yellow spots are sharply pointed and angular and extend towards the middle of the segment. The second segment is subcylindrical, brownish black and about two and one-fourth to two and one- half times as long as its posterior width ; the sides are almost parallel but the segment is slightly wider anteriorly. Just past the middle there are a pair of nearly transverse, yellow, medially enlarged spots which are narrowly separated. Third segment about one and a half times wider posteriorly than basally and a little longer than twice its basal width. Tt is brownish black with a pair of slender, posteriorly rounded, but wider and widely separated, submedial yellow vittae. Lying outside of these vittae posteriorly are two short, yellow, wedge-like spots. All four of these vittate spots end a considerable distance from the posterior margin of the segment but the submedial pair are slightly longer. Fourth segment similar in general pattern to the third, the segment equally wide anteriorly and posteriorly, the submedial vittae of the same position, width and thickiu-» but extending closer to the posterior margin, the outlying pair of vittae also originating at the base of the segment, extending 232 ENTOMOLOGICAL NEWS [Nov., '49 two-thirds the length of the segment and distinctly but slightly curved towards the medial vittae leaving the concavity lateral. The fourth segment is about one-fourth to one-third longer than wide. The fifth segment is half as long as the fourth, the middle pair of vittae slightly convergent, the outer pair like those upon the fourth segment originating at the base but wider basally than the submedial pair and much shorter; they, there- fore, appear as acute wedge-shaped spots. Hypopygium pol- ished brassy or brownish black. Pile of abdomen everywhere blackish. Female. Similar in nearly every respect to the male, the front is widely blackish in the middle with narrow, yellow, lateral margins which reach as far as the anterior ocellus. The wings are perhaps slightly wider but tend to be a little paler, leaving a slightly accentuated, very large, brown, quadrate, darker spot in the middle. . This is perhaps due to tenerality of which there is some evidence. However, the last section of the first posterior cell as measured by a transverse line through the lower end point of the subapical cross vein is shorter. This cross vein is then more sigmoid. Abdomen: similar to the male, the second segment is not quite twice as long as wide, the third and fourth are a little shorter. The fifth is somewhat longer and larger and the sixth is about one-fourth as long as the fifth and is transverse with the posterior margin in the middle a little bit rounded and elevated. The total width of the abdomen is slightly greater. Holotypc: male, Chanchamayo, PERU, August 19, 1948, J. Schunke. Allotypc: female with the same data, but August 11, 1948. Paratypcs: three males, June 20- Aug. 11, and Aug. 19, 1948. In the author's collection. Salpingogaster urania n. sp. Related to conipressa Curran. This species is distinguished by the subapical spur upon the second vein and the absence of a brownish yellow border upon the second cubital vein. Length 15.5 mm. Male. Head: face and cheeks pale yellow, the front very dark shining red, prominent and protuberant with a narrow, Ix, '49] ENTOMOLOGICAL NEWS 233 conspicuous, bright yellow margin along the eyes, meeting at the eye junction but confined to the upper half of the front only. Preantennal callus concolorous with front. First antennal seg- ment of the same color. Second and third segments brownish red, the third smoky brown on the dorsal half, the arista light brown at the base, dark brown apically. Pile of front short, subappressed and black. Pile black on the upper part of the face, short, fine and yellow below. Vertex shining black. Occiput black except ventrally where it is yellow, the pollen pale grey, the pile yellowish white becoming more reddish above. Thorax: mesonotum dark reddish brown except as follows : the humeri, a wide band along the notopleura to the transverse suture, a spot medial and adjacent to the humeri and the posterior calli, all light yellow. The posterior portion of the mesonotum also becomes more yellowish pollinose. Also on the mesonotum there are three, quite obscure, narrow, dark reddish sepia vittae. The outer pair are a little expanded where they cross the suture and all three are narrowly con- tinued to within a short distance of the scutellum. Scutellum pale yellow with a faint, transverse, light brown band occupying most of the disc except the immediate base. Mesonotal pile short, subappressed and yellowish. Scutellar pile still shorter, sparse, yellow with a few minute microscopic black setulae. Pleura reddish brown, a diagonal yellow stripe confluent with the notopleural band runs down the posterior margin of the mesopleura and ends in a small spot on the upper sternopleura. Squamae dark brown, upper squamae more reddish. Halteres yellow, the knob sepia. Legs: anterior and middle femora and tibiae entirely rich light yellow, their basitarsi more yellow, their remaining tarsi more of a pale orange brown, their coxae reddish sepia. Hind femora yellowish in the middle and api- cally. diffusely reddish brown basally and subapically. Hind tibiae entirely yellow with yeltow pile. Hind tarsi orange brown, ll'ings: nearly hyaline, the entire costal cell, the sub- costal cell as far as the pterostigma, the marginal cell as far as the pterostigma yellow in color. The basal portion of the upper half of the first basal cell, the narrow margin along the 234 ENTOMOLOGICAL NEWS [Nov., '49 cubital vein as far as the niediocubital cross vein, narrowly margined with yellow. The pterostigma is very dark sepia, almost blackish. The marginal cell from the base of the ptero- stigma outward and the end of the submarginal cell is also dark- sepia. The end of the marginal cell, in both wings, in five specimens, has a distinct short spur. The loop of the third vein is extremely deep, suboblique and rounded. The subapical cross vein bulges far outward on its apical two-thirds and is deeply kinked inward on the basal portion. Alulae narrow and pale, scarcely wider than the basal section of the costal cell. First segment of abdomen pale yellow, narrowly reddish along the posterior margin, except laterally, second segment quite long and subcylindrical, light red in color, except narrowly on the basal margin which is pale diffusely yellowish. The third segment is narrow basally and reddish brown becoming widely expanded posteriorly and dark reddish sepia. Fourth segment a little wider basally than posteriorly and also dark reddish sepia throughout. Fifth segment of the same color but less than half as long as the fourth segment. The fourth segment is barely shorter than the third and the third segment is approxi- mately three-fifths as long as the second. Hypopygium light brownish red, conical and ending in a rather sharp point pos- teriorly. The fifth sternite turns straight downwards in two brownish red lobes, densely beset with rather long, stiff, bristly black hairs. Holotypc: male, Chanchamayo, PERU, June 8, 1948.

KNOWLTON, Utah State Agricultural College, Logan A five-spotted ladybird beetle, Hippodainia quinqnesignata Kirby, was found to be feeding on a tiny wingless aphid, Phoro- don incnthac (Ruckton), on M cntha spicata at Nephi, Utah, June Ix, '49J ENTOMOLOGICAL NEWS 235 26, 1945. An adult of this ladybird also was observed at Well- ington, Utah, June 14, 1945, feeding on a wingless aphid, Capitophorus clongatns Knit., on rabbitbrush, Chrysothamnus IUIHSCOSHS. An adult five-spotted ladybird also was found to be feeding on a pea aphid. Macrosiphum pisi (Kalt.). in net sweepings made in an alfalfa field at Freemont, in Wayne County, Utah, on July 10, 1943. In the same net, an Orius tristicolor Wh. was feeding on a winged western flower thrips, I'niitkliniclla inoitltoni Hd.. which was quite abundant in the field. At Amalga, Utah, June 27, 1938, ladybird adults and larvae, syrphid larvae and other predators of aphids were moder- ately abundant in a field of canning peas which was suffering pea aphid injury. Both a five-spotted and a convergent ladybird beetle were observed to feed on pea aphids. At Avon. Utah, both these ladybird beetles and also ladybird larvae were moder- ately abundant on July 17, 1945, on sugar-beets raised for seed and on which the green peach aphid, Mysits pcricac (Sulzer), was moderately abundant. Here an adult five-spotted ladybird was found to be eating a winged pcrsicac, while at Cedar City, Utah, on July 3, 1946. an adult specimen of this predator species fed on a mature wingless hollyhock aphid, Macrosiphum coessigi Knit. Ladybird beetles of several species were present among a heavy infestation of this injurious aphid. At Axtell, Utah, May 14, 1943, a five-spotted ladybird was observed to be eating a small alfalfa weevil larva. A convergent ladybird, H. con- vcrycns Guerin, was eating a Capitophorus clongatns on Chry- sothauunts, ten miles north of Panguitch, Utah, June 28, 1945. Aphids of this species were abundant and three species of lady- bird beetles were present on this infested rabbitbrush. An adult Coccinclla transversoguttata Fald. was found while feeding on an Aphis Jiclianthi Monell on a sunflower leaf at La I'oint, Utah. An Anatis Iccontci Csy., collected in Logan Canyon. July 5. 1943, ate 399 pea aphids in nine days, with a maximum of 78 fourth instar Mac. pisi eaten in one day. The two-spotted ladybird beetle, Achilla bipunctata ( L.), was observed to feed on the following insects: Capitophorus clonga/ns on Chrysothamnus inutscosus at Circleville, Utah, July 11. 1(M2; 236 ENTOMOLOGICAL NEWS [Nov., '49 on Myzocallis tiliac (L.), on Tilia americana at Brighani City, Utah, June 21, 1943; on Macrosiphum coessigi on heavily in- fested hollyhock plants which apparently had been stunted by the severe aphid attack, at Provo, Utah, July 16, 1946, and again to be eating an aphid of the same species at Lethbridge, Alberta, Canada, July 27, 1946; and Phorodon incnthae on ditchbank spearmint at North Farmington, Utah, July 9, 1947. For sev- eral weeks this Mcntlta spikata was heavily infested with this little aphid which in turn was attacked by numerous larval and adult ladybird beetles of several species, as well as by large num- bers of Onus tristicolor, besides fewer Anthocoris inelanocerus Renter, and syrphid and aphid-lion larvae. An Adalia frigid a (Schw.), collected at Echo, Utah, June 29, 1943, was brought into the college laboratory. Although offered 19 fourth-instar pea aphids, it ate only one and died on the third day. Obtaining, Reading and Filing Microfilm By KATHRYN M. SOMMERMAN, Washington, D. C. A film library seems to be the solution to some of the diffi- culties I have encountered in taxonomic work in entomology. In many instances I have found it impossible to procure reprints of needed articles and in some cases I have not been able to obtain journals from the library, or often they are in use when needed. The U. S. Department of Agriculture Library, Washington 25, D. C. has a Photocopying Service for private individuals. Articles are furnished on 35 mm. film, or as photoprints. Re- quest forms for Photocopying Service are mailed upon request. A separate Request Form is required for each article. The completed forms (as complete as possible) giving: "Author, Title, Periodical Title, Volume, No., Date and Pages inclusive" are mailed to the Library along with Library Coupons, Check or Money Order. When ordering, 1 request the numbers under which the order is processed, which makes it easy to keep track of the film because it is not always all returned at one time. It is also convenient to refer to back orders bv num- Ix, '49| ENTOMOLOGICAL NEWS 237 her instead of repeating the whole reference, in case errors are made in the filming process. Under "Pages inclusive" I also request' "Title page" so there will be no question later when citing the reference for publication.* . • « Glass (cut Uo) \ / G'uC ' ptatt qlujS To Topv frame on o" 5 JM line cof Two **S mm 0— insert film hc»C FIG. 1.

Notes on Ixodes scapularis Say with an Additional Lizard Host By RICHARD B. EADS, Bureau of Laboratories, State Depart- ment of Health, Austin, Texas I.vodcs ricinus Linnaeus and the closely related species 7. scapularis Say and /. pacificus Cooley and Kohls exhibit little host specificity, particularly in the immature stages. Various authorities list a wide range of hosts for these species, including representatives of the Classes Mammalia, Aves and Reptilia. Parasitism of reptiles by ticks of the genus I.vodcs appears con- fined to the ricinus complex. Nuttall and Warburton (1911). after various authorities, chiefly Neumann (1809). list this spe- cies from lizards taken in the following countries : Italy — im- mature forms from Laccrta iniiralis and L. riridis; Spain — liz- ards of different species ; Albania — larvae, nymphs and adults from Laccrta ayilis, L. arcnicola and L. vivipera; Africa — larvae and nymphs from Laccrta occllata and Tropidosaurus alf/irns; and Asia — from lizards. Nuttall and Warburton (1911) also record the adults of I.vodcs ricinus from a wide variety of mammalian hosts and lar- vae and nymph from avian and mammalian hosts. In the United States lizards have been reported as hosts of the immature stages of 7. scapularis and 7. paci/icus. Bishopp and Trembley (1945) give the lizard, Sccloporus occidcntalis. as host for nymphal 7. pacific us. Cooley and Kohls ( 1945) re- port larvae and nymphs of I. pacificns from Gerrhonotus scinci- Ix, '49] ENTOMOLOGICAL NEWS 239 cauda, G. coendens, G. multicarinatus, Sceloponts occidentalis and Cnemidophorus sp. in California. Gregson (1942) records larvae and nymphs of this species commonly parasitizing Gcr- rhonotns principis in British Columbia. Bishopp and Trembley (1944) give one record of a larva and nymph of /. scapular is being recovered from the lizard, Scelo- porus iniditlatus. During studies on Bullis fever in Bexar and Comal Counties, Texas, Brennan (1945) recovered nymphs and larvae of this species from the lizards : Lciolcpisina iniicolor, Sccloporus oliraccns and S. undulatiis. Hixon (1941) records 123 larvae and 8 nymphs of /. scapularis from two Plcstiodon fasciatus and 42 larvae and 6 nymphs from Sceloporus undulatiis. The hosts were collected near Gainesville. Florida. Since no larval and few nymphal records of /. scapularis from birds or mammals have been made by personnel of this Labora- tory, we were particularly interested in the recovery February 19, 1949, by Tom Moore, Texas Fish, Game and Oyster Com- mission, of an I. scapularis, partially engorged nymph, from a glass-snake lizard, OpJiisaurus z'entralis Linnaeus, taken on the Aransas Federal Game Refuge, Aransas County, Texas. Veri- fication of the identification of the tick was made by Drs. J. C. Bequaert, Harvard Museum of Comparative Zoology, Cam- bridge, Massachusetts, and G. M. Kohls, Rocky Mountain Lab- oratory, Hamilton, Montana. The specific determination of the lizard was made by Tom Moore. State Department of Health records indicate the black-legged tick, I.vodcs scapularis, to be the most common I.vodcs in Texas. In the southern and eastern part of the state adults have been commonly taken from deer, raccoon, gray fox. red wolf, tree squirrel and bobcat. Twenty-six deer trapped by the Texas Fish. Game and Oyster Commission on the Aransas Federal Game Refuge were exam- ined for ectoparasites in December. 1948. The animals were uniformly infested, particularly about the head, with adult /. scapularis. Deer taken from this refuge are sent to other Texas counties, other states and possessions of the United States. Consequently it was considered advisable that they leave the 240 ENTOMOLOGICAL NEWS [Nov., '49 heavily infested game refuge in a tick-free condition, if possible. With this objective in mind the twenty-six deer were sprayed with a one per cent \vettable DDT at the rate of a pint per ani- mal. Before spraying, each animal was parasitized by twenty to twenty-five I. scapularis. Twenty-four hours after spraying only an occasional tick was found which could still feebly move its legs. Summary : A nymphal Lvodes scapular is has been taken from an apparently new lizard host, Ophisaurus ventralis. Adult /. scapularis were controlled on deer by spraying individual ani- mals with a pint of one per cent wettable DDT. LITERATURE CITED BISHOPP, F. C., and H. L. TREMBLEY. 1945.

It resembles M. fumipennellus (Fitch) in having two pair of prothoracic tubercles, but in M. youngii the front pair are larger and longer than the second, while the opposite is the case in fumipennellus, which is a much darker species. 242 ENTOMOLOGICAL NEWS [Nov., '49 Notes on the Lace Bug, Gargaphia iridescens Champion By GEORGE P. WENE, Texas Agricultural Experiment Station, Weslaco The lace bug, * Gargaphia iridescens Champion, was first found severely injuring young tomato plants on March 23, 1947, in a single field near Mission, Texas. In mid September this insect was found in small numbers on black-eye peas and can- ning beans in the dry land area around Harlingen. On Sep- tember 26 of the same year heavy infestations occurred on all varieties of beans near Weslaco. A few days later young lima bean plants collected in the Brownsville area had from 5 to 10 lace bugs per leaf. Injury occurred only on very young bean plants and was first noticed on bean plants in the 3 or 5 leaf stage. The first symptom is usually a yellowing of a portion of a leaf. On the underside of the leaf can be found numerous black excrement spots about the size of a pencil point. As the feeding progresses the entire leaf turns yellow, slowly wilts, and finally drops off, resulting in a stunted and sometimes a dead plant. Even a single lace bug could severely stunt a young bean plant that had only the two cotyledon leaves. The nymphal stage is passed on the young bean plant. As many as 30 nymphs have been found on a single leaf. As a rule most of the nymphs will be found on a single leaf of a plant. Migration to the other parts of the plant usually takes place after the adult stage is reached. Both nymphs and adults prefer to feed on the younger and more tender leaves of the bean plant, and practically always on the lower surfaces. Heavy infestations of this insect have also been found on young volunteer cotton plants during September and there is information available that indicates destructive infestations on local experimental plantings of guayule during 1944 and 1945. * Thanks are due to Dr. R. I. Sailer of the U.S.D.A., Division of In- sect Identification, for the identification of this insect. Ix, '49] ENTOMOLOGICAL XK\VS 243 So far, the author has been unable to find any uniform infes- tations of lace bugs. Heavy and damaging infestations were found in areas up to one-tenth of an acre in size distributed at random throughout the field. These areas were so numerous in many fields that growers were forced to dust with 5.0 per cent DDT in order to save their bean crops. No lace bug infesta- tions were seen during the 1948 season. It will be interesting to see if this insect will become a serious pest of vegetables at some future date. Diplops desertorum a Scorpion Synonym By HERBERT L. STAHXKE. Poisonous Animals Research Laboratory, Arizona State College. Tempe, Arizona The scorpion, Diplops desertorum, designated as a new species by Stanley Mulaik and Harold G. Higgins in ENTO- MOLOGICAL XKWS, Vol. IV, No. 9, November, 1944. must be considered as a synonym of Superstitionia doncnsis, designated and described by the author in the IOWA STATE COLLEGE JOUR- NAL OF SCIENCE, Vol. XV. No. 1, October 1940, pp. 101-103. In the same publication this species was placed in the family Chactidae and a new subfamily created, Superstitioninae. A full description of both the new species and new subfamily was given in an Iowa State College doctor's dissertation en- titled, 'The Scorpions of Arizona." 1939. The authors, Mulaik and Higgins, were unaware of the ex- istence of the Iowa State Journal article and should be com- plimented on their very excellent description. It is so clear that there can be no question as to the species designation being a synonym. 244 ENTOMOLOGICAL NEWS [Nov., '49 Current Entomological Literature COMPILED BY RAYMOND Q. BLISS AND R. G.

INC., Lancaster. Pa. ENTOMOLOGICAL NEWS VOL. LX DECEMBER, 1949 Xo. 10 A Pictorial Review of the North American Chipmunk Fleas P,\ C. ANDRESEN HUBBARD, Vanport College, Portland 3. Oregon Foreword : Chipmunks have long been favored pets among small boys and girls in this country. Usually they are trapped by the youngsters in the fields and forests about and kept either in cages or on a string to crawl about the person and hide in the pockets. At times pet shops feature chipmunks for chil- dren's pets. In certain localities over the country both the chipmunks and certain of their fleas have been found plague positive. The chipmunks and their fleas should, therefore, be watched carefully by health agencies. It is because of the plague possibilities involved that this paper becomes of importance. Part One — MONOPSYLLUS EUMOLPI (Roths. ) : with four new subspecies. Close to the turn of this century Brooks and \Yenmann were collecting fleas in British Columbia and Alberta, Canada for Charles Rothschild, who was working them in England as a hobby and probably for relaxation from the business worries of the great banking concern bearing his name. Among other fleas to arrive in England was a series off Canadian chipmunks. Rothschild studied these until 1905. during which year he de- scribed them as Ccratopliyllns eitinolpi but which are known today as FEB 2 i 1950 254 ENTOMOLOGICAL NEWS [Dec., '49 Monopsyllus eumolpi (Rothschild). 1905 Ccratophyllus eumolpi Rothschild, Nov. Zool., 12:161. This, the parent species, of what in this paper involves 6 subspecies, has the following pattern and characteristics in the modified segments. Male : Finger roughly rectangular to ham- shaped, with characteristic armature consisting of 3 spiniforms on the posterior border, the lower one long, the two upper ones short and either straight or hooked, the 3 usually, but not always, equidistant. The writer doubts that the exact position of the middle spiniform or the straight or hooked condition is of any taxonomic value. Process P. is apically dome shaped. Female: The apical outline of the VII sternite is with upper lobe only, the lobe half round to squarish. The spermatheca is barrel-shaped with bent, finger-like appendix. The bursa is very prominent and readily marks these female fleas from others. The normal hosts for this group of North American fleas are members of the rodent genera Tamias and Eutamias and are commonly known as chipmunks. However, gray and red squirrels are about as frequently infested by these fleas and the predators of the three groups also carry them. As one views the six subspecies here considered, side by side, it is evident that the face of the modified segment towards the investigator gradually diminishes in surface from one end of the series to the other. This review is arranged according to the amount of surface of the modified segment in the sub- species under consideration. In the series of 6 here repre- sented, the one with the greatest expanse of modified segment is Monopsyllus eumolpi charlestonensis, a new subspecies. There are before the writer at this time the holotype male, the allotype female, a paratype female and 4 paratype males, taken off Palmer's Chipmunk (Eutamias palmcri) (type host) at the base of Charleston Peak in Kyle Canyon, Spring Moun- tains (type locality) 25 miles northwest of Las Vegas, Clark County, NEVADA on 25 June 1945. They bear the writer's collection number 2395. Ix, '4' *| ENTOMOLOGICAL NEWS 255 Modified Segments : Male. Finger ham-shaped, slender and longest of the series. Distance from long spiniform to articu- lation with Process longest in the series, the angle the great- est. Process, high dome-shaped and narrow apically, posterior apical angle rounded. Female. Lohe on VII sternite very large and low down, squarish, with posterior horder turned up. Bursa is long, slender and coiled ; inconspicuous. Length: Both male and female measure about 2.25 mm. Range: Probably throughout Spring Mountains in western Clark County, Nevada. Deposits : Holotype and allotype on one slide in U. S. Na- tional Museum, paratypes in Depositories maintained by writer. This flea bears the name of the mountain upon which it was collected. The second of the series shall be called Monopsyllus eumolpi wallowensis, a new subspecies. There are before the writer at this time the holotype male, the allotype female and a series of paratypes collected at Wal- lowa Lake, Wallowa County, OREGON (type locality) off Orange-bellied Chipmunk (Eutamias a. hiteiventris} (type host) on 13 July 1939. They bear the writer's collection number 1618. Modified Segments : Male. Finger ham-shaped, broad and slightly shorter than in preceding subspecies. Distance from long spiniform to articulation with Process shorter and the angle less than in preceding. Process dome-shaped but broad and low and with posterior apical angle angulate. Female. Lobe of VII sternite long, narrow and low down on outline. The angles are rounded. Bursa is the most prominent of the series. Length: Both male and female are just under 3 mm. Range: This flea is found in the Wallowa Mountains of northeastern Oregon and probably in the Blue Mountains of northeastern Oregon and southeastern Washington. Deposits: Holotype and allotype on one slide in I*. S. Na- tional Museum, paratypes in Depositories maintained by tin- writer. 256 ENTOMOLOGICAL NEWS [Dec., '49 This flea hears the name of the Oregon county in which it ranges. Note: During the War years Hubhard was unable to secure type slides from Abroad, therefore he could not compare chip- munk fleas collected in the West with the types. In "Fleas of Western North America," page 237 illustrations under item 122. M. eumolpi eumolpi are of this new subspecies as are the "Records" for Oregon on page 238. The third of the series is Monopsyllus eumolpi cyrturus (Jordan) 1929. 1929 Ceratophyllus eumolpi cyrturus Jordan, Nov. Zool., 35 : 34. Through the kindness of Dr. Karl Jordan of the Tring Branch of the British Museum there are before the writer 2 pairs of paratypes from Paradise, Cochise County, ARIZONA collected 19 October 1913 off skunk by O. C. Duffner. The writer has personally collected materials from the South Gate of Grand Canyon National Park, Arizona taken off Gila Chipmunk on 4 July 1945. While the collection localities are some 200 miles apart the male fleas are similar but the outline of the VII ster- nite female differ somewhat. The writer doubts the differences enough to create two valid subspecies. Modified Segments: Male. The finger becomes less ham- shaped to approach the rectangular shape of the following sub- species. Jordan claimed for one of the characteristics the more flattened apical border. The distance between long spiniform and articulation with Process is shorter than in the preceding and the angle is less. The Process is apically high, narrow and dome-shaped. Female: VII sternite of paratype from type locality has small rounded lobe high up on border but specimens taken by the writer at Grand Canyon have a larger upper lobe which is angulate. The bursa is prominent. Length : Both sexes measure about 2.50 mm. in length. Range : Known only from Arizona south and east of Grand Canyon. Deposits : The types are in the Tring Branch of the British Museum. Ix, ' ENTOMOLOGICAL NEWS 257 o o 258 ENTOMOLOGICAL NEWS [Dec., '49 Note: Hubbard writing on page 238 in Fleas of Western North America, item 123. M. c. cyrtunis should have referred all collection records except those under Arizona to J\I. e. cuuiolpi and the accompanying illustration 123. M. eumolpi c\rturns is not an illustration of cyrtunis but of M. c. eitinolpi. The fourth of the series is Monopsyllus eumolpi eumolpi (Rothschild) 1905. 1905 Ccratophylhts cinnolpi Rothschild, Nov. Zool., 12: 161. There are before the writer 2 pairs of paratypes through the courtesy of Dr. Jordan, the large collection of slides of this subspecies in the collection of the Rocky Mountain Laboratory, through the courtesy of Dr. William Jellison, those in the col- lection of the Plague Suppressive -Measures Laboratory, through the courtesy of Frank Prince and Harold Stark, speci- mens from Wyoming collected by John Wiseman and speci- mens from Utah collected by Vernon Tipton. The writer's own collection contains hundreds of specimens of these fleas from all over the West. Modified Segments : Male. The finger is less ham-shaped and approaches the rectangular. The apical border presents quite an angle. The distance from the long spiniform to ar- ticulation with the Process is much shortened and the angle less than in the preceding subspecies. Process is apically nicely rounded and dome-shaped with posterior apical angle angulate. Female : VII sternite with lobe variable, high up on outline and either wide or narrow and usually apically rounded. The bursa is prominent. Length : Males and females around 2.50 mm. in length. Range : Extensive, north of Grand Canyon, Arizona in Rocky Mountains into Alberta, Canada ; west to Crest of Cascade Mountains and in favorable locations as in the Siskiyou Moun- tains of southern Oregon and northern California on almost to the Pacific Ocean ; north from southern Nevada and central Sierra Nevada Mountains of California to and into British Columbia, Canada. Deposits : Types are in the Rothschild Collection of the British Museum. Ix, '49] ENTOMOLOGICAL NEWS 259 Note : All of the records offered by Hubbard in Fleas of Western North America under subspecies of Monopsyllus eumolpi are of this subspecies with the exception of specimens from 'Arizona and Wallowa County, Oregon. These records appear on pages 238 to 241 inclusive. In the fifth of the series the proportions of the modified seg- ments again become reduced, the finger becoming smaller, the outline VII sternite female with long narrow lobe. It shall be called Monopsyllus eumolpi canadensis, a new subspecies. There are before the writer at this time the holotype male, the allotype female mounted on a single slide and 2 pairs of paratypes also mounted a male and female to the slide. The specimens were collected in Ontario, Canada (type locality) off chipmunk (type host) 19 July 1947 by W. Watson. Modified Segments : Male. Finger is suggestive of preced- ing but is apically more rectangular. The apical border is still at quite an angle. Distance between long spiniform and ar- ticulation with Process shortest of the series so far discussed and the angle is less. The Process is apically high dome-shaped with posterior apical angle well rounded. Female : Lobe of VII sternite high on outline and long and fairly narrow, apically angulate but rounded in the allotype. Bursa weak yet evident. Length : Both sexes measures a little over 2.00 mm. Range : Eastern Canada and probably northeastern United States. Deposits: Holotype and allotype in U. S. National Museum; paratypes in British Museum and Canadian National Museum. This flea bears the name of the country from which it wax described. The sixth of the series represents M. eumolpi with the modi- fied segments in their most diminutive size. It shall be called Monopsyllus eumolpi americanus, a new subspecies. There are before the writer at this time the holotype male, the allotype female mounted on one slide personally collected in Painted Desert, Coconino County. ARIZONA (type locality) off Desert Chipmunk ( fintain ias niiiocnns} (type host) on 7 260 ENTOMOLOGICAL NEWS [Dec., '49 July 1945 and the following paratypes : 4 males and 10 females from the collection of the Rocky Mountain Laboratory collected in south central COLORADO and 1 male and 5 females collected by Harold Stark in southeastern UTAH in San Juan County. Modified Segments : Male. Finger most rectangular of the series. Apical border almost at right angles with anterior and posterior borders. Distance from long spiniform to articula- tion with Process and its angle shortest of the series, the angle almost a right one. Process while still dome-shaped is very low and flat. Posterior apical angle very noticeable and angu- late. Female : Lobe VII sternite most reduced in the series, in the allotype finger-like and high, in paratypes, high, from long finger-shaped to small rounded. Bursa the most reduced in the series, inconspicuous. Length : In spite of the reduced size of the modified seg- ments this flea is as big as the others in the series and measures about 2.50 mm. in length in both sexes. Range : East Approaches of the Rocky Mountains north of Little Colorado River. Probably also found in the Great Plains where chipmunks are found. Deposits : Holotype and allotype are deposited in U. S. Na- tional Museum. Paratypes are returned to owners. Key to Subspecies of Monopsyllus cuinolpi by Range 1. Northeastern United States and adjacent Canada. M. e. caiiadensis 2.

There is Ix, '49J ENTOMOLOGICAL XK\VS 261 little doubt that as new isolated areas are found and studied new differences will appear and new subspecies. Also there are minor differences within the above six but as the writer views them now he is disinclined to make more separations. In 1943 Ewing and Fox removed cumolpl from the genus Monopsyllns and placed it in the genus Trichopsylla. Few American flea students have accepted this change and most siphonapterists hold that Ewing and Fox are in error and the change was not warranted. Enrique Schmidt (1864-1948) The death of Enrique Schmidt in December 1948 in San Jose, Costa Rica, marked the passing of one of the outstanding collectors of Tropical American insects. Enrique, or Henry, as he was better known to his American correspondents, was born January 20, 1864, at Stargard, Pom- erania, Germany, the son of Julius and Albertine Schroder Schmidt. In 1891 he came to America, staying first at New York, later going to Galveston. Texas, where he worked for five years for the late Colonel E. M. House, friend and adviser of President Woodrow Wilson. In 1906 he removed to Costa Rica where he was to spend the remainder of his life. Since 1911 he lived and worked as a horticulturist on the largest coffee plantation in Costa Rica, "La Caya," 8 kilos to the west of San Jose, lying on the Pacific watershed at an altitude of about 1150 meters. La Caya lies between two rivers, the Rio Virilla and the Rio Torres, very broken mountainous country that provided wonderful insect collecting over the many years. From his earliest days in America, Schmidt was a capable and most energetic collector of insects. Throughout his life he suffered from tuberculosis of the bones which in 1927 neces- sitated the removal of his right leg. Later he lost the sight of one eye, the hearing of an ear. and suffered the removal of several diseased ribs. Despite all such physical handicaps, he continued his collecting of insects virtually to the end ot his life. In 1927, following the loss of his leg. he attempted to earn his 262 ENTOMOLOGICAL NEWS [Dec., '49 livelihood through the collecting and sale of insect specimens. Schmidt concentrated his attention on certain groups, among them the Thysanura, Collembola, Thysanoptera, Corrodentia, micro-Diptera, micro-Coleoptera, and the Hymenoptera, par- ticularly the ants and bees. About 1913 he became particularly interested in ant guests. A short time before his death Schmidt wrote that "when I began collecting not a single ant guest was known from all Costa Rica while now we know them by the hundreds." Schmidt himself published little or nothing, but his vast collections have been used in hundreds of publications by others. It is estimated that at least one hundred species of insects that he discovered bear the specific name "schmidti." C. P. ALEXANDER Dr. Hermann A. Eidmann Notice has been received of the death of Dr. Hermann A. Eidmann, Professor of Zoology at the University of Gottingen, on September 4, 1949 at Mitten wakl, Oberbayern. Dr. Eid- mann's interests among entomological subjects were wide ; be- sides a well-known general textbook, he has published numerous articles on forest entomology and on ecology with special ref- erence to insects. In the last decade of his life, he wrote many fine ecological studies of exotic ant faunas, and it is for this work with the ants that he is perhaps best known in the United States, although his earlier morphological studies are also highly regarded here. At the time of his death. Dr. Eidmann was at work on a number of projects, including an ecological survey of the ant fauna of Tibet and neighboring areas. He was noted for his ability to cooperate with other specialists throughout the world, and I am sure that others besides the present writer will feel keenly the loss of such an accomplished counselor. Dr. Eidmann is survived by his wife. Hilde. and two daughters. W. L. BROWN, JR. Ix, '49 1 ENTOMOLOGICAL NEWS 263 Current Entomological Literature COMPILED BY RAYMOND Q. BLISS AND R. G. SCHMIEDER.

INC., Lancaster. Pa. ENTOMOLOGICAL NEWS VOL. LXI JANUARY, 1950 No. 1 The Genus Allaporus Banks (Hymenoptera, Pom- pilidae) : Notes and Descriptions By HOWARD E. EVANS, Kansas State College, Manhattan, Kansas The curious North American Pompilid genus Allaporus has been considered to contain but a single species, the several other described species having been correctly placed in synonymy with ritfircntris Cresson by Bradley (1944). Recently, however, several specimens have come to my attention which are un- doubtedly specifically distinct from the widely distributed rnfi- ventris, and represent two new species which are here described. Both of these are at present known from the female sex only. The species of Allaporus now known may be separated by the following key. KEY TO THE SPECIES OF ALLAPORUS (FEMALES) 1. Vertex distinctly extended above the tops of the eyes, the posterior ocelli about equidistant from each other and from the crest of the vertex, which is quite sharp ; mandibles unusually broad, somewhat angled about one-third the distance from the base, thereafter flat and polished ainabilis new species Vertex not or scarcely extended above the tops of the eyes, the posterior ocelli much nearer the vertex than to one another ; mandibles normal, not modified as above 2 2. Front femora slightly incrassate, their maximum width about .4 their length ; crest of the vertex rather sharp ; front only slightly convex in profile, below forming a prominence on the lower side of which are located the antennal orbits inc.vicaniis new species Front femora not incrassate, their maximum width about .,•> their length ; vertex crest rounded ; front strongly convex in profile view nilircnlris (Cresson) (1) 2 ENTOMOLOGICAL NEWS [Jan., '50 Allaporus amabilis new species Length 7 mm. ; fore wing 5.3 mm. Color black, except as follows : abdomen ferruginous except for the extreme base of the first tergite, which is black ; all the legs beyond the trochanters dusky-ferruginous ; mandibles dark ferruginous ; clypeus and scape with a tinge of ferruginous. Wings hyaline, lightly in- fuscated on the apical fourth. Entire body clothed with a fine, pale, more or less silvery pubescence. Mandibles broad, with two weak teeth on the inner margin ; shaft of mandible bent slightly inward about one-third the dis- tance from the base, the outer portion of the mandible with a flat, shining surface, in a plane oblique to that of the clypeus when the mandibles are closed. Clypeus elevated, plate-like, about twice as broad as high, its apical margin truncate. Front broad, at the middle about .68 times the maximum width of the head ; eyes converging slightly above, the distance between the eyes at the top .9 the distance between them at the bottom. Front in profile only slightly convex, the spatium frontale (the lower median part of the front, just above the antennal orbits) not prominent, not overhanging the bases of the antennae. Vertex elevated considerably above the tops of the eyes, in anterior view very slightly arched, almost straight across ; crest of the vertex thin and acute. Posterior ocelli about as close to the crest of the vertex as to each other, and slightly closer to each other than to the margins of the eyes. Antennae of mod- erate length, the first four segments in a ratio of about 3:1:2:2; scape slender, about three times as long as thick, slightly curved. Propodeum rather long, with a short, oblique posterior de- clivity, the sides of which are distinctly transversely rugulose. Front femora slender, the maximum width .25 times the length. Legs very weakly spinose for the genus, the spines on the middle and hind tibiae very minute. Apical abdominal sternite strongly compressed. The single topotypic paratype resembles the type closely in all details, except that the legs are a somewhat brighter fer- ruginous.

Paratype: $, same data as type except taken on 16 July 1931 [United States Na- tional Museum]. Allaporus mexicanus ne\v species Length 7.5 mm. ; fore wing 5 mm. Color black, except as fol- lows : abdomen bright ferruginous, except the extreme base of the first segment, which is black ; hind femora and tibiae dusky- ferruginous ; apex of mandibles dusky-ferruginous. Wings sub- hyaline, lightly infuscated on the apical fourth. Entire body clothed with a conspicuous pale, more or less silvery pubescence, except on the upper front, vertex, and thoracic dorsum, where it is brownish. Mandibles of the usual shape in the Pompilinae, not modified as in the preceding species, the shaft curving gradually, the outer apical portion shining, but not presenting a broad, flat sur- face ; inner margin with two weak teeth. Clypeus nearly three times as broad as high, its apical margin truncate, the disc not elevated but on the same plane as the lower front. Eyes very narrow, the front broad between them, in the middle about .72 times the maximum breadth of the head ; inner orbits not con- verging above, the distance between the eyes at the top the same as at the bottom. Front in profile only slightly convex, the spatium frontale, however, quite prominent, forming a V-shaped elevation somewhat overhanging the antennal orbits. Vertex in anterior aspect straight across, in fact very slightly concave, elevated only very slightly above the tops of the eyes ; crest of the vertex rather sharp. Posterior ocelli close to the vertex crest, much closer than they are to each other ; post-ocellar line equal to the ocello-ocular. Antennae short, the first four seg- ments in a ratio of about 3:1:2: 2.3 ; scape stout, only slightly more than twice as long as thick. Propodeum rather long, with an oblique, slightly concave pos- terior declivity, on the sides of which the propodeum is slightly transversely rugulose. Front femora slightly incrassate, the 4 ENTOMOLOGICAL NEWS [Jan., '50 maximum width .38 times the length. Legs moderately spinose, the middle tibiae in particular with rather strong spines. Apical abdominal sternite scarcely compressed. The single paratype closely resembles the type, but the middle tibiae and femora are ferruginous, and the front legs brownish; it is 6.5 mm. long, the fore wing 4.5 mm. Holotypc: $, Cuernavaca, Morelos, MEXICO, May 1945 (H. L. H. Krauss) [United States National Museum]. Paratype: ?, Brownsville, TEXAS,, 8 June 1937 (R. H. Crandall) [Cornell University] . Allaporus rufiventris (Cresson) The synonymy and a redescription of this species have been given recently by Bradley (1944). In addition to the localities cited by Bradley, I have seen this species from Pennsylvania (Pittsburgh), Georgia (Rockmart), and from Berkeley, Cali- fornia. ON THE SYSTEMATIC POSITION OF ALLAPORUS This genus was assigned by Bradley (1944) to the tribe Aporini, and placed systematically between the genera Chcla- porus and Rhabdaponts. However, it differs markedly from these genera and from all Aporini in the structure of the hind wing. The radial vein is very short to the point where it meets the transverse cubital ; the cubital vein is also unusually short before its junction with the transverse cubital vein ; the trans- verse median vein leaves the anal at an angle, rather than form- ing an arch as in most Pompilidae. Furthermore, the anal lobe is slender, and deeply separated from the remainder of the wing. These features are not shared by any Aporini known to me ; they are, however, diagnostic of certain Old World genera placed by Arnold (1936, 1937) in the tribe Idopompilini. In fact, Alla- porus keys readily to this tribe in Arnold's key to the tribes and genera of Psammocharinae (1937, p. 75). Specimens of Micro- p had 11 its pit in Hits Costa, a member of the Idopompilini, are be- fore me, and compare favorably with the species of Allaporus, although there are a number of generic characters by which they Ixi, '50 J ENTOMOLOGICAL NEWS 5 differ. Many structural features of the body, and the venation of the fore wing, as well as the unusual venation of the hind wing, suggest a close relationship of Allaporus with the Idopompilini. If the Idopompilini are maintained as a tribe distinct from the Aporini, the balance of characters would appear to place Alla- porns in the former tribe. In any event, note should be taken of the close similarity of Allaporus to Microphadnus and certain related Old World genera. REFERENCES CITED ARNOLD, G. 1936.

Type specimens will be deposited in the collection of the Acadamy of Natural Sciences of Philadelphia. Nannaria scutellaria Causey 1942 Great Smoky Mountains National Park : Greenbriar Cove, Double Spring Gap, Ramsey Prong, Cherokee Orchard, a site between park headquarters and Gatlinburg. Forty-eight larvae of the 4th, 6th, and 7th stadia ; 43 adults. All of the larvae and some of the adults were dug from the soil. Tucoria dynama Chamberlin 1947 Kentucky Ridge State Forest. Two males. Faded tri- maculate. 6 ENTOMOLOGICAL NEWS [Jan., '50 Apheloria roanea Chamberlin 1947 Kentucky Ridge State Forest. One male and one female.

Sixteen males, two of which were dug from the soil. The median dorsal spots in some individuals were smaller than the colored areas on the keels ; in others they were low wide tri- angles confluent writh the colored keels ; and in some there was a colored band across the posterior margin of most of the tergites.

Aporiaria deturkiana Causey 1942 Great Smoky Mountains National Park : Rainbow Falls Trail, Rocky Springs Gap, Greenbriar Cove, Double Spring Gap. Twenty-seven males, 19 females, 7 larvae. All of the larvae and some of the adults were dug from the soil. Brachoria hansonia sp. nov. Kentucky Ridge State Forest, Pineville, Kentucky. One male (type) ; length 49 mm., width 11 mm. Three females, length 51 mm., width 11 mm., from the same site are assigned tentatively to this species. The shape is typical of the genus, wide keels and moderately arched dorsum. Color in life unknown ; faded brown type suggests brightly colored keels and wide bands across posterior margin of tergites and completely around the collum. Legs and venter light. Coxae posterior to gonopods spined. Sternum bluntly spined. Ixi, '50] ENTOMOLOGICAL NEWS 7 The telopodite of the gonopods (Fig. 1) has an inconspicuous transverse ridge about midway of its length. Otherwise it forms a wide smooth curve, resembling the telopodite in species of Aphclorla. The gonopods most closely resemble those of se- qitcns; in that species the telopodite is crossed by two transverse ridges, while there is only one in hansonia. The telopodite is sparsely setose on the outer curve below the ridge and smooth beyond it. The simple acuminate median blade is shorter than the longest of the hairs in the basal tuft. .5 MM FIG. 1.

Deltotaria brimleardia, end of telopodite of right gonopod, sublateral view. Deltotaria brimleardia sp. nov. Great Smoky Mountains National Park, Tennessee : Ramsey Prong. One male (type) ; length 27 mm., width 6.2 mm. The body is relatively wide and only slightly arched. Color in life unknown. The type was dug from the soil be- fore the adult colors had developed. Coxae spined. Sternum not spined. The gonopods closely resemble those of briinlcii. but they can be distinguished by the shape of the free end of the telopodite 8 ENTOMOLOGICAL NEWS [Jan., '50 and the distribution of the setae on it (Figs. 2, 3) . The telopo- dite forms a smooth curve and ends in an acuminate process sub- tended by a thin rounded lobe. In brimleii the acuminate process is bent back toward the lobe, forming an apical hook. The middle half of the telopodite is setose on the outer curve. The large coxal peg is typical of the genus and is entirely distinct from the medial coxal hook or hiiftlwrnchen. A Review of the Genus Pseudolithobius (Chilopoda : Gosibiidae) By RALPH CRABILL, JR., Cornell University, Ithaca, New York Among the material collected during the summer of 1948 by Mr. George Ball and Dr. Howard Evans, to whom I am greatly indebted, is a new member of the endemic Nearctic genus, Pseudolithobius. This new species is of particular interest be- cause it is the second to be placed in the genus since its erection in 1875 by Stuxberg. Pseudolithobius (Stuxberg) Lithobius Stuxberg, Ofvers.

Ixi, '50] ENTOMOLOGICAL NEWS 9 The present genus is distinctive within the Gosibiidae in hav- ing the last five pairs of coxae with ventral pores. All other known genera of Lithobiomorph centipedes, with the exception of the Henicopid genus, Zygethobhis, bear coxal pores on only the last four pairs of legs. Pseudolithobius, which has been known since 1875 from a single species, megaloporus, has only been taken on the west coast of the United States. With the discovery of the new Arizonan form, festinatus, described be- low, the areal distribution of the genus is considerably increased. Generic Diagnosis. Fulvous or reddish brown forms, rang- ing in size to 41 mm. Lateral head margins essentially con- tinuous, no true marginal breaks occurring, although an indis- tinct line visible where the usual breaks would occur. Ocelli in two or three series ; posterior ocellus largest ; entire eye area small, elongate. Antennae short, consisting of twenty to twenty-two articles. Prosternal teeth recurved, 3-3 to -1 — \ ; ectal spine setiform. Tergites rugose, roughened ; the ninth, eleventh, and thirteenth produced posteriorly, or none so pro- duced. Coxal pores on last five pairs of legs. Female gonopod claw large, entire. Basal spines stout, 2-2, 3-3, or 4—4. First article of gonopod broad, well chitinized mesally, constricted basally on inner side. Fifth article of penult and ultimate legs of the male conspicuously modified. (The penult and ultimate legs of megaloporus show such sexually dimorphic character- istics, it is assumed that when a male of jestinatus is found, it too will exhibit such modifications.)

Prosternal teeth recurved, 3-3 to 4-4. Tergites nine, eleven, and thirteen with posterior outer corners distinctly pointed and produced posteriorly. The last five pairs of legs with coxal pores. Last two pairs of legs with coxae laterally armed. Ventral spinulation of the tenth to penult pairs of legs, 0, 1,3, 3, 3, the penult legs sometimes 0, 1, 3, 3, 2. That of the first to tenth pairs of legs, 0, 0, 3, 3, 3. Ventral spinulation of the ultimate legs, 0, 1, 3, 3, 1, with two terminal claws, the second one minute. Dorsal spinulation of first to ninth pairs of legs, 0, 0, 3, 3, 2, of the tenth to the ultimate pairs of legs, 1, 0, 3, 3, 2. Basal spines of female gonopods 3-3 or 4-4. Pseudolithobius festinatus sp. n. Like the Californian, megaloporus, this new species has coxal pores on the last five pairs of legs, but it may be readily distin- guished from megaloporus in having none of the tergites pro- duced posteriorly and in having only the last pair of coxae laterally armed. Furthermore, festinatus has only two basal spines on each female gonopod as opposed to three or four in megaloporus; the adult female specimen of fcsiinatits is only 13.5 mm. in length, and the ultimate leg spinulation is dorsally 1, 0, 3, 1, 0, ventrally 0, 1,3, 2, 0, thus contrasting significantly with that of megaloporus, viz. dorsally 1, 0, 3, 2, 2, and ventrally 0, 1,3,3, 1.

Comparison of paratypes of my 1935 species with specimens which I determined in 1925 as A. cincticornis leaves me no doubt of this synonymy. Ixi, '50] ENTOMOLOGICAL NEWS 13 II Students and cataloguers of the aquatic Hemiptera, without exception, appear to have overlooked the fact that Champion himself renamed his Corixa sexlineata in a footnote under the List of Plates on p. xvi of Volume II of the Biologia, where he wrote : "This name is preoccupied in the genus, and is here changed to sexcincta." Because of this oversight the species was renamed by Kirkaldy in 1909, and it was again renamed in 1927 by Jaczewski who overlooked both the previous cor- rections. In this country it has generally been known as Trichocorixa naias (Kirkaldy), and appears under this name in Sailer's recent monograph of Trichocorixa (Kans. Univ. Sci. Bull. 32 : 335, 1948). The full synonymy of the species is : Corixa sexlineata Champion, Biol. Centr.-Amer., Hem.-Het. 2 : 379, Tab. XXII, fig. 22, Feb. 1901. [Name preoccupied.] [Corixa} scxcincta Champion, op. cit., p. xvi, footnote, June 1901. [New name.] [Arctocorisa] naias Kirkaldy, in Kirkaldy and Torre-Bueno, Proc. Ent. Soc. Wash. 10(3/4) : 196, 1909. [New name for sexlineata Champ.] "C[orixa]" (now with all probability Trichocorixa) championi Jaczewski, Ann. Zool. Mtis. Polon. Hist. Nat. 6 (3) : 257, footnote 2, 1927. [New name for sexlineata Champ.] When I called this to the attention of Dr. Sailer, he replied, "The fact that Champion's note . . . has been missed by so many workers who have used this volume as a principal refer- ence for almost half a century is most remarkable." I concur in this ; but I cannot except myself from the list of those who missed it, for I used this volume of the Biologia for nearly thirty years before this footnote caught my eye. It may be noted here that 1908 is generally cited as the date of publication of "A catalogue of American aquatic and semi- aquatic Hemiptera," by Kirkaldy and Torre-Bueno, in which Kirkaldy proposed the name naias for this species. It was published in the September-December. 1908, issue of the Pro- ceedings of the Entomological Society of Washington ; but Torre-Bueno noted in 1911 (Can. Ent. 43: 226, footnote) that it did not appear until June or July of 1909. The author's ex- tras bear the date May 17, 1909. 14 ENTOMOLOGICAL NEWS [Jan., '50 Charles F. Adams Dr. Charles F. Adams, M.D., 72, dipterist and Public Health official, died on January 21, 1950 at his home in Jefferson City, Missouri. From 1903 to 1908 he published on the taxonomy of Diptera, including two articles contributed to ENTOMOLOGI- CAL NEWS (15: 303-304; 16: 108-111), and the keys to the genera of Dexiidae and Tachinidae in the third edition (1908) of Williston's "Manual of North American Diptera." Though for many years his professional career was in Public Health Administration, as Director of Laboratories for the Indiana State Board of Health (1927-1934) and Missouri Division of Health (1934-1949), he continued his keen interest in Diptera and. maintained a large collection and library. At the time of his death he was Acting Director of the Missouri Division of Health. Dr. Adams was a kindly and lovable gentleman who will be sincerely missed by those privileged to be his friends. CURTIS W. SABROSKV In Behalf of Dr. Hermann Weber The "Lehrbuch der Entomologie," published in 1933 by Dr. Hermann Weber, is generally considered to be the outstanding p^eneral text-book of our science. Dr. Weber is also known for o his "Biologic der Hemipteren," without doubt the finest exam- ple of a combined morphological and biological treatment of an individual order of insects, and for his "Grundriss der Ento- mologie," an unsurpassed shorter text-book, now in its second edition. Dr. Weber has indeed done much for entomology and for entomologists, and he is now asking for help in order that he may continue his labors more effectively. Undiscouraged by the loss of his library, his collection, his reprints, and all his possessions, Dr. Weber is presently en- gaged in preparing a second edition of his famous text-book. The scientific library facilities at Tubingen are limited, and Dr. Weber writes that he would be enormously helped if entomolo- gists would send him reprints of their scientific papers, their recent ones as well as any they may have directed to him before 1945. In addition, papers on all zoological subjects are needed for he is collaborating with Prof. A. Kiihn on a revision of the Ixi, '50] ENTOMOLOGICAL NEWS 15 Claus-Grobben "Lehrbuch der Zoologie," and writing the chap- ters on morphology and ecology and the special part except Protozoa and Coelenterata.

Habitat. CALIFORNIA. Holotype: <$, Truckee River, along small spring-fed rill near Deep Creek, Placer Co., 5.950 feet, July 2, 1947 (C. P. Alexander). Paratopotype : 1 <£. July 1, 1947. While generally similar to species such as Ormosia (Ormosia) incitjcnu (Osten Sacken), the present fly is very distinct in the structure of the male hypopygium. particularly the unusually complicated phallosome. Ormosia (Ormosia) burneyensis new species Belongs to the similis group; mesonotum dark reddish brown, the pleura more yellowed; antennae (male) elongate, exceeding one-half the length of wing, the flagellar segments nodulose, the basal swellings of the individual segments long-fusiform ; cell M2 open by the atrophy of the basal section of M3 ; male hypo- pygium with the mesal margin of the basistyle produced into a blackened bispinous structure; phallosome on either side of aedeagus produced into two spines, the outer one small. J1. Length about 4-4.5 mm. ; wing 4.5-5.4 mm. ; antenna about 3-3.2 mm. Rostrum and palpi brown. Antennae (male) elongate, ex- ceeding one-half the wing; scape and pedicel yellow, flagellum dark brown ; flagellar segments long-fusiform, the basal swell- ings conspicuous, provided with dense whorls of long pale setae that exceed the segments in length and are considerably longer than the dark verticils. Head dark brown. Pronotum brown, the pretergites whitened. Mesonotum dark reddish brown; pseudosutural foveae reddish; pleura more yel- lowed. Halteres pale. Legs with the coxae and trochanters yellow ; remainder of legs brownish yellow, the outer tarsal seg- ments slightly darker.

Venation: Cell M2 open by the atrophy of the basal section of Mz; m-cu at fork of M; vein 2nd A sinuous on distal third. Abdomen, including hypopygium, dark brown. Male hypo- pygiun\ with the appendage of the ninth tergite unusually wide, the apical emargination very broad and shallow, the lateral lobes correspondingly stout and obtuse, with long pale fimbria- tions. Outer dististyle with the rows of scabrous points re- duced, more or less restricted to the outer fourth. Inner disti- style a little longer, the apex obtuse, weakly darkened. Basi- style on mesal margin produced into a blackened bispinous structure, the lower spine smooth, the outer or axial one stouter, bladelike, the outer margin and apex microscopically serrulate. Phallosome stout, abruptly narrowed into the aedeagus, at point of narrowing each outer lateral angle produced into two spines, the outer one small, the inner long and straight, decussate across the midline. Habitat. CALIFORNIA. Holotype: $, Hatchet Pass, Burney, altitude 4,200 feet, July 9, 1947 (C. P. Alexander). Paratopo- type: J1. Paratypes: ffi, Castle Crags State Park, Shasta Co., altitude 2,050 feet, August 13, 1948 (C. P. Alexander).

JV Length about 3.5-3.6 mm. ; wing 4-4.2 mm. ; antenna about 2 mm. $. Length about 4—5 mm. ; wing 4.5-5.5 mm. Rostrum yellow; palpi black. Antennae (male) long, ex- ceeding one-half the body ; scape obscure yellow, the remaining Ixi, '50] ENTOMOLOGICAL NEWS 35 segments brownish black ; flagellar segments unusually nodose, each with a major basal enlargement that is provided with long outspreading setae, additional to a single even longer verticil ; longest ordinary seta about as long as the segment ; verticils approximately one-third to one-half longer than the segment ; distal half or less of segment narrowed, glabrous. In alhcrtcn- sis, the segments are fully as long but are narrower basally and not so strongly nodose, with the ordinary setae shorter and dis- tributed over the entire segment with the exception of the outer fifth or sixth.

Abdominal tergites dark brown, the sternites in male more yellowed ; genitalia of both sexes yellow. Male hypopygium about as in albertensis or oncrosa. Habitat. CALIFORNIA. Holotypc: <$, Truckee River, along small spring-fed rill near Deep Creek, Placer Co., 5,950 feet, June 30, 1947 (C. P. Alexander). Paratopotypcs, JJ; para- types, J^, Upper Echo Lake, near Freeborn Cabins, 7,500 feet, July 4. 1947 (C. P. Alexander). The various species that center about Ormosia (Ormosia} mesoccra Alexander, including besides the latter, 0. (O.) al- bertensis Alexander, O. (0.) oncrosa Alexander and the pres- ent fly, are all closely inter-allied, as well shown by the very uniform structure of the male hypopygium. However there are well marked differences in the structure of the antennae, ranging from the short inconspicuous structures of oncrosa to the con- dition found in the present fly. The most nearly allied species is alhcrtensis where the basal swellings of the flagellar segments are much less developed, as described above. 36 ENTOMOLOGICAL NEWS [Feb., '50 First Record of Adult Mountain Midges from North America. (Diptera: Deuterophlebiidae) * By ROBERT W. PENNAK, Department of Biology, University of Colorado Although the larval and pupal stages of mountain midges have been collected from the substrates of rapid streams in Col- orado, Utah, Wyoming, Oregon, and California (probably all Deutcrophlcbia coloradensis Pennak), the imagoes have not heretofore been recorded from North America. Of the several Asiatic and Japanese species, the imagoes of only three have been briefly described. At 8 :00 A.M. on July 19, 1948, however, the writer was for- tunate enough to collect about 200 dying, dead, and disintegrat- ing adult males and 2 adult female D. coloradensis floating in small side eddies of North St. Vrain Creek near the town of Lyons, Colorado, at an altitude of 5320 feet. Many larvae and pupae had previously been collected from this foothills stream. Although the streamsides in the area and farther upstream were examined carefully, not a single adult specimen could be found on the vegetation, on the rocks, or in the abundant cob- webs. This fact strengthens the contention of other investiga- tors that mountain midges are poor fliers that cannot do more than flutter about weakly and briefly above the water after emergence. They soon fall to the surface of the water and die. Late morning and afternoon collections from North St. Yrain Creek have never yielded imagoes, and it appears probable that they emerge only in the early morning hours. Nothing is known about their copulation and oviposition habits. Detailed descriptions of the adult male and female are in preparation. * Contribution No. 16, Limnology Laboratory, Dept. of Biology, Uni- versity of Colorado. Ixi, '50] ENTOMOLOGICAL NEWS 37 Two New Polydesmoid Diplopods By NELL BEVEL CAUSEY, University of Arkansas, Fayetteville, Arkansas Type specimens of the species described in this paper have been deposited in the collection of the Academy of Natural Sci- ences of Philadelphia. The collections were made by the author. EURYURIDAE Auturus florus n. sp. Figs. 1 and 2. This species is close to A. niiinctcs in size, coloration, and the general shape of the gonopods. It differs from A. mimetes in that the lamina ectad of the hooked blade of the gonopods is roughly pointed rather than rounded. The color of adult specimens is dark grey with orange keels and median spots. Antennae, legs, and underparts are white. The last tergite is roughly quadrilateral with the caudal mar- gin slightly convex and the sides subparallel. The keels of the 18th and 19th tergites are rounded ; posterior corners of the preceding tergites are a little acute. The keels are thickened on the edges, with the pore lateral and about midway, its site marked by a slight swelling or sometimes by a slight excava- tion. The usual small tooth is just posterior to the anterior corner of the keels. The gonopods in situ hang down, directed slightly forward, with the amber colored ends overlapping. Distally they are flattened with the edges forming a rough trough open medially and terminally. The distal margin has a thin rounded hooked process medially and a longer rough peak laterally. The distal one-fifth of the gonopods is glabrous and of a bright amber color; the remainder is the usual cream color and the surface is setose, thickly so on the medial and ventral surfaces. Length of male holotype 29.5 mm., width 3.4 mm. Length of female allotype 30 mm., width 4 mm. Locality. ARKANSAS : Hemmed-in-Hollow, Compton, New- ton County, July 13, 1940. In the collection there were three 38 ENTOMOLOGICAL NEWS [Feb., '50 males, four females, 15 larvae of the 7th stadium and six of the 6th stadium. Others have been taken at Pyatt in Marion County and at several places in Washington County. FIG. 1. Arturus florus n. sp. Left gonopod of male holotype, caudal view, X 28. FIG. 2. Same, cephalic view, X 28. FIG. 3. Dcltotaria tcla n. sp. Left gonopod of male holotype, sub- cephalic view, X 28. FIG. 4. Right gonopod of male holotype, distal end of blade, cephalic view, X 55. FIG. 5. Same, subcaudal view, X 55. XYSTODESMIDAE Deltotaria tela n. sp. Figs. 3, 4, and 5 This species resembles D. briiuleii, but it can be distinguished by the differences in the thin expanded end of the gonopods. See figs. 3, 4, and 5. The gonopods of the male paratype showed great similarity to those of the holotype at low power magnification, but at medium power the differences were very noticeable. Ixi, '50] ENTOMOLOGICAL NEWS 39 The preserved specimens are brown, and the light colored keels are confluent with wide hands of color across the posterior margins of the tergites. The dorsum is moderately arched. The keels are wide, slightly overlapping ; their margins are thickened, and the pores are on the upper surface behind the middle. The head and first three segments are much narrower relatively than in most of the other broad flat members of this family. Posterior coxae are sharply spined ; sternites are unarmed in the male, but very bluntly spined in the female. Length of male holotype 36 mm., width 8.2 mm., width of collum 5.6 mm. Length of male paratype 32 mm., width 8 mm., width of collum 5.5 mm. Length of female allotype 38 mm., width 10.2 mm., width of collum 6.5 mm. Another ma- ture female in the collection tentatively assigned to the species has the following dimensions : length 34 mm., width 7 mm., width of collum 5 mm. Locality.

MUNROE, Institute of Parasitology, Macdonald College, Quebec Since the appearance of my recent remarks on this subject I have received two very interesting papers (Travassos and d'Almeida, 1937; Travassos, 1946), which help to fill an im- portant gap in the data then available to me. These papers contain very full descriptions of the larvae of several species of Neotropical Saturnioidea, including those of three species of Agliinae: Dysdaemonia lauicrlan Maassen & Weymer, Machaerosema martii (Perty), and Copioptery.v scniirann's (Cramer). In all three species the subventral tubercles seem to be lacking in the first and all subsequent instars. A possible 40 ENTOMOLOGICAL NEWS [Feb., '50 exception is in the early instars of Dysdaemonia, in which there is said to be a transverse row of prothoracic spines approxi- mated to the head ; this may be compared with Packard's (1914:9) description of the first instar larva of Arsenura rich- ardsoni, in which there are said to be two subspiracular pairs of tubercles on the prothoracic segment. In both cases a further study of the homologies is desirable. The remarkable dorsal armature of the young larvae strongly suggests an affinity with the Citheroniinae, and this relationship has been accepted by most recent authors. The similarity to the larva of Aglia is very close, and the subfamily is probably a natural one. If this is so, its geographical distribution forms a remarkable parallel to that of the Dismorphiinae, with a re- stricted and probably primitive genus in the Palearctic region, and a relatively diverse assemblage of strikingly specialized forms in tropical America. The larvae of the Agliinae must be considered more specialized than those of the Citheroniinae not only in the complete suppression of the armature in the final instar but also in the absence of the subventral and ventro- lateral rows of tubercles in the earlier stages of development. In the paper by Travassos and d'Almeida some further Saturnioid larvae are described. Citheronia phoronea (Cramer) and Syssphinx molina (Stoll) lack the subventral tubercles on all segments in the final instar. The more dorsal series are also considerably reduced in S. molina, but in C. phoronea these seem to be entirely normal. These two species would thus differ from the Citheroniinae listed in my table. Two Hemileucinae agree well with those already listed : Automeris acuniinata Maassen & Weymer has subventral tubercles on thoracic segments 1 to 3 and abdominal 1. 2, and 7 to 9; Dirphia multicolor Walker has them on thoracic 1 to 3 and abdominal 1, 2, 7, and 9. Both species are described from the fifth (final) instar. REFERENCES MUNROE, E. G. (1949) An unnoticed character in the Saturnioidea (Lepidoptera). ENT. NEWS, 60:60-65.

Medical Entomology is an anomalous science which as usually defined includes within its boundaries at least portions of several other sciences, and is a subject on which it is practically im- possible to obtain all of the necessary correlated information. Professor Matheson with his long teaching experience has de- veloped, in at least certain portions of the science, the insight which is essential to those working or interested in the field, and much of this has been made available in the present work. This, the second edition of the book, is completely rewritten following the form of the original edition and includes numerous additional illustrations. Progress in the field is so rapid that any book of this kind is naturally behind the most recent dis- coveries. This has been duly noted by the author who states that he has attempted to bring together the data available by the end of 1948, a statement which should prove helpful to those desiring to check for the most recent developments. This avail- able information is scattered in such a variety of journals, mainly medical and entomological, but also in those covering more general fields, as well as in separate works, special reports, bulletins and government publications in many different lan- guages that it is a tremendous undertaking to try to bring together the more important facts so that they may be presented in a single volume. A number of the aspects covered in the book are themselves the subject of large separate studies or of well established serial publications. The present volume deals with the subject from the ento- mologists' aspect of the problems involved, leaving almost all of the effect on humans to the medical profession. Such parasitol- ogy as is included is only that necessary to understand the transmission of pathogens. Particularly stressed is the taxonomy and morphology of those insects, and certain related groups of arthropods, which either affect man directly by their habits or which act as vectors or carriers of organisms pathogenic for man. Sufficient morphol- ogy is discussed, particularly under the various major groups, to give one a general picture of the group, to use the keys pre- sented and to understand the mode of transmission of patho- gens. This latter, of course, necessitates in almost all cases a Ixi, '50J ENTOMOLOGICAL NEWS 55 good working knowledge of the morphology and mode of action of the mouthparts and digestive system. In most cases keys are given to separate at least the more important forms that occur in North America. Some of these keys are not strictly dichotomous and it is believed that this may cause some con- fusion for persons not moderately well acquainted with insect taxonomy. Although in most cases structures mentioned in the text are well illustrated, a short glossary would be helpful to many of those for whom the volume is intended. General life history information and bionomics are discussed under each major group and then, in most cases, additional more detailed information concerning the more important forms is presented. This style of treatment is used for those found in North America and in some groups for those of equal or of greater importance in other portions of the world. Following this is a section on the relation of the forms discussed to dis- eases. Most of the major diseases involved are treated in a short summary of the methods of transmission ; the known or suspected vectors, reservoirs and hosts are also listed. It is in the information included under bionomics and the relation to disease that so much has been accomplished in recent years. In these sections the author and year are often cited in relation to findings or conclusions but unfortunately in some cases it is not possible to find the complete reference in the bibliographies. This omission will cause some inconvenience to those with libraries available but places those without extensive biblio- graphic facilities at a distinct disadvantage. All of the chapters have selected bibliographies as it would be impossible to make any attempt at completeness in a work of this size. This selection appears to be moderately well bal- anced but does have the limitation above noted, as well as that of including some references that could readily be omitted. This book is in an easily readable form but unfortunately a number of editorial lapses are noted. In addition the continuity occasionally is not what might be desired. All in all it is a worthwhile addition to the field of Medical Entomology and should prove to be of value to most of those interested in any way in this field. — ]. \\T. FT. RFITX.

INC., Lancaster. Pa. ENTOMOLOGICAL NEWS VOL. LXI MARCH, 1950 No. 3 Ceratomia kansensis new species (Sphingidae) BY EDWIN W. HOWE and WILLIAM H. HOWE, Ottawa, Kansas Ceratomia kansensis new species Ceratomia kansensis offers many analogies to C. catalpae Bdv., but some major differences. While differing markedly from C. nndnlosa Wlk., in some respects it more closely resembles this species than it does C. catalpae. The general coloration of the upper side of the wings of both sexes of C. kansensis is somewhat similar to that of C. catalpac, being a greyish-brown rather than shades of brown. Distinct markings are noticeably absent from the upper surface of both wings of C. kansensis, the dark lines found near the apex of the fore-wing of C. catalpae being so greatly reduced in the new species as to be vestigial. The under surface of both wings of both sexes of C. kansensis is lacking in distinct markings of any sort. The white fringe spots found along the outer margins of both fore- and hind-wings in both C. catalpae and C. nndnlosa are completely lacking in the male of C. kansensis in both wings, are lacking in the fore-wing of the female and vestigial in the hind wing of the female C. kansensis. While the general appearance of C. kansensis is rather similar to that of C. catalpae the shape of the wings is quite similar to that found in C. nndnlosa. The fore-wing in both sexes of C '. kansensis has the costal margin rather strongly convex, and the inner margin decidedly sinuate. We figure the wings of C. undulosa, C. catalpae and C. kansensis to show this. It will (57i 58 ENTOMOLOGICAL NEWS [Mar., J50 also be noted that the costal margin of the hind wing of C. kan- scnsis is decidedly convex. This is true in both sexes. FIG. 1. Ceratomia kanscnsis n.sp., male. C. kansensis agrees with Rothschild and Jordans' description of C. catalpac in the following respects : In both sexes of C. kanscnsis, the first segment of the fore- tarsus is slightly longer than the second. The terminal spur of the hind tibia (both sexes) is less than two-thirds the length of the first tarsal segment. Collar not edged with buff. In both sexes of C. kanscnsis, the yellowish area on the meta- notum is not distinct, thus agreeing with northern speci- mens of C. catalpac. C. kansensis differs from C. catalpac not only in the shape of the wings, but the stigma is much smaller and is nearly round. Ixi, '50] ENTOMOLOGICAL NEWS 59 All wing markings are less distinct than in C. catalpac. This is particularly true of the underside of the wings, which are devoid of any distinct markings, though a faint band does appear along the basal side of the hind wing in both sexes.

Clasper small, narrow, broadest just before end; harpe short, broad almost oblong, upper margin slanting, dentate." Penis sheath with only a mod- erately long, horizontally curved apical tooth. Female : the vaginal plate closely resembles that of C. ratal pae. Drawings of the wing shape and venation are included for C. undnlosa, C. catalpac and C. kanscnsis for comparison. The affinities of C. kanscnsis are clearly closest to C. catalpac, in general ; but the shape of the wings more closely resembles C. undnlosa. C. kanscnsis is known to the describers only from Kansas, but is rare here. \Ye know of only two males and one female so far collected in Kansas. One male was taken at Ottawa, KANSAS, on August 2nd, 1947. A second male was taken at Ottawa, KANSAS, on August 27, 1947. One female was taken at Baldwin Junction, KANSAS, on August 21, 1949. All three specimens were collected after dark and at lights. The food plant of the larvae, the larvae themselves, and the species distribution are unknown to the describers. All three specimens listed above were used in making the description. One male, the type, is in the collection of the describers at Ottawa, Kansas. The second male, the paratypc, is in the collection of James Hoffman, Ottawa, Kansas. The female, the allotype, is in the collection of Margaret M. Gary, Philadelphia, Pa. Lxi, '50] ENTOMOLOGICAL NEWS 61 A New Subspecies of Speyeria atlantis (Edwards) from Nevada (Lepidoptera: Nymphalidae) By ARTHUR H. MOECK, Milwaukee 7, Wisconsin SPEYERIA ATLANTIS GREYI, new subspecies The subspecies of Speyeria atlantis (Edwards) (1863, p. 54), described below, was first obtained by the author in 1946, while collecting at high altitudes in the East Humboldt Range, near Wells, Elko County, Nevada. A return trip in 1948 yielded no further specimens, but a week's sojourn in the area in 1949 yielded sufficient material to indicate that this isolated strain is constant, and rather sharply distinct from atlantis subspecies hitherto mentioned in the literature. Above, both sexes have the light reddish buff ground color found in the Great Basin Speyeria, similar to atlantis chitonc (Edwards) (1879, p. 82) and atlantis z^asatchia (dos Passes and Grey) (1945, p. 9), rather than the ruddy hue of Rocky Mountain subspecies such as atlantis hcsperis (Edwards) (1864, p. 502). The dark pattern markings are reduced, and for atlantis, as Grey who checked the genitalia points out, most remarkably subdued. The subspecies wasatchia and chitonc usually are thought of as presenting the extreme of atlantis variation toward pallidity, but in both of those Utah races the dark pattern marks are relatively bolder and the basal suffusion more evident than in this Nevada greyi. Below, the color of the discal area of the secondaries is pale brown with dusting of greenish silver overlay, the spots often being edged lightly with pale olivaceous green. In no speci- mens examined were there any individuals approaching in discal variability to the light brick or sordid red coloration characteristic in other Southwestern atlantis populations. This absence of red hues, and the presence of light brown shades similar to those seen in serene plafina (Skinner) (1897, p. 154), is a color departure apparently new to observed tend- encies of atlantis variations. The spots are well silvered ; the band is pale straw, usually sharply defined. 62 ENTOMOLOGICAL NEWS [Mar., '50 Expanse: Small, of a size with the Sierran atlantis Irene (Boisduval) (1869, p. 601). Holotype, 56 mm., allotype, 58 mm., measured from wing-tip to center of thorax, doubled. The 15 male paratypes showed a size variation from 52 mm. to 58 mm. ; the 6 female paratypes a range from 54 mm. to 62 mm., measured as mentioned above. Type Material: The holotype male was taken by the author in Lamoille Canyon, Ruby Mountains, Elko County, NEVADA, on July 24, 1949, at an elevation of about 8,500 feet. The allotype female was taken in the same valley on July 27, at an elevation nearer 8,000 feet. There are 21 paratypes, as fol- lows : 10 males and 3 females taken in, near, or above Lamoille Canyon, ranging in elevation from 7,000 to 10,000 feet; 4 males and 3 females taken along the snow of glaciers, close to 10,000 feet, above Angel Lake, East Humboldt Range, Elko County, Nevada, on July 29, 1946; and 1 male at the Angel Lake area on July 29, 1949. It may be of interest that the largest female (62 mm.) was the only specimen of the 23 taken near the 7,000 feet mark, if not actually below, and that the smallest female (54 mm.) was perhaps the only specimen taken at over 10,000 feet. The majority were taken at an elevation of about 8,500 feet. Of the total specimens taken, namely 23, only 7 males and 4 females, or a total of 11, are in good or fair condition, the rest being taken in various degrees of "worn condition." Remarks: The significance of the departure in coloration of this atlantis is interesting, and remains to be evaluated. Our greyi, an extreme in atlantis pallidity, was flying sympatrically with an extremely pale serene form identified as cynna (dos Passes and Grey) (1945, pp. 4-5), which latter was taken in goodly numbers. As no other atlantis forms have so far come to light from among material collected by the author on a dozen mountain "islands" across Nevada, between the Utah border and Lake Tahoe in California, it may well be that greyi is deeply isolated, as the distinctive color development would suggest. The author is the process of persuading L. P. Grey to evaluate this mass of material collected across the Great Basin, from the "Mesa" in Colorado to "Tahoe" in the west, with the hope that Ixi, '50 1 ENTOMOLOGICAL NEWS 63 such an analysis might add to recorded knowledge of Spcyeria variation. The dos Passes and Grey Catalogue of Speyeria (1947, pp. 1-30) has been used as a guide to nomenclature and subspecific relationships.

H. REHN x The Blattaria of the United States and Canada are undoubt- edly one of the better known groups of insects. This group has been treated comprehensively by Hebard, and studies of the larger genera have been published. However, no concise key to the genera has been prepared, that presented by Hebard being more involved than is necessary to separate the twenty-six known genera. My thanks are given to Professor V. S. L. Pate of the De- partment of Entomology of Cornell University for his interest in the preparation of this work. In addition the key has been tested in course work at that institution and its then apparent weakness has, I hope, been removed. 1 Research Associate, Department of Insects, Academy of Natural Sciences of Philadelphia.

R. DREISBACH, Midland, Michigan Banks erected the genus Alasagenia to include those species in the Subfamily Auplopodinae which had a distinct petiole, a beard of long hairs under the head on nientum, last joint of mid and rear tarsi bare of spines beneath and on sides, venation very similar to the other genera, with the basal vein in fore wings basad of the transverse median and the subdiscoidal vein in rear wings ending before the origination of the cubitus ; and the posterior tibiae with a row of distinct spines above and with a row of short bristles on each side. The genotype is a species from British Guiana, but at the time of the description of the genotype Banks stated that there were other species from the United States that went in the same genus that had been described in Priocnemis, but that differed from that genus by virtue of the petiolate abdomen. These species are A. reynoldsi (Banks), A. fulgifrons (Cres- son), A. incitiis (Banks) and the new species described also belongs here. At the present time there are no photomicrographs of the genitalia of any of the males available, but when they do become available they will be published. Alasagenia rubineus n. sp. Holotypc female : Head, thorax, and legs black, with the abdomen completely red ; the head, thorax and legs covered with short, glistening, finely appressed whitish hair, the abdomen just as completely covered with similar hair but due to the red color does not show up as prominently as on the head and thorax ; the head when seen from in front appears to be longer than wide, but actually the width and length are of the same dimensions ; inner orbits parallel ; the ocellar triangle stands out very slightly above the otherwise flat vertex ; clypeus truncate in front and slight reddish on front edge ; when seen from the side Lxi, '50] ENTOMOLOGICAL NEWS 69 the clypeus is slightly raised above the face at base but almost flat from there to tip ; the clypeus and face much more closely covered by the glistening white hair than any other part of body; when seen from the side, the nearer ocellus is just visible above the vertex of eye, about one third of the front just back of antennae is raised above the surface of eye; the posterior orbits widest opposite the insertion of the antennae, and there about equal to the eye in width, and narrowing very consider- ably from there to vertex ; fore ocellus slightly more than its diameter from the laterals and these about two thirds as far apart as their distance to eyes ; antennae inserted about the lower third of eye, about one third the length of basal joint of antennae from clypeus ; head very finely punctured with a slightly granular appearance ; a few long hairs on vertex, with quite a few more on clypeus and under clypeus ; mandibles slightly reddish at tip ; basal antennal joint three times as long as second, but only three fourths as long as third, which is sub- equal in length to fourth, succeeding joints about the length of third except the last two which are only about two thirds as long; whole antennae covered with stiff short brownish hair, and is very slender ; a very prominent beard of hairs under head on mentum which are curved slightly forward ; a fairly long flat pronotum which is transverse behind and appears slightly granular ; the propodeum slopes in a smooth curve from base to tip ; second abdominal ventral segment with a very evident transverse groove ; wings almost hyaline but slightly smoky, much more so beyond cells ; marginal slightly shorter than its distance to wing tip; third cubital cell about one third longer on cubitus than the second, but the second cubital cell is one third longer on the marginal vein than the third cell ; first recur- rent vein is received by the second cubital cell at about the middle, while the second recurrent vein joins the third cubital cell slightly beyond the middle. Basal vein in fore wings slightly basad of the transverse, and with a rather deep bend forward just before it meets the cubital vein ; the cubitus vein in rear wings arises exceptionally far beyond the subdiscoidal ; no spines on femora, fore tibiae with four small spines on under side and about 8-10 at tip ; the last two pair of tibiae well spiix-d 70 ENTOMOLOGICAL NEWS [Mar., '50 on outer side and on the dorsal surface, with two or three small ones near tip on under side ; very small and short spines on tarsi, smaller and fewer on the first joint, and these becoming larger and more numerous from first pair of legs to last pair; the fourth tarsal joint of the first two pair of legs shorter than the fifth joint without the claw, but this joint in rear legs as long as fifth joint; a fairly large tooth about middle of claw; legs long and slender; longer spur of posterior tibiae about three eighths as long as its metatarsal joint ; there are no spines on sides or under the last joint of posterior tarsi. Size : Head and thorax 3.7 mm., abdomen 3.0 mm., fore wing 8.60 mm., rear wing 3.85 mm. Holotype female : Washington, DISTRICT OF COLUMBIA, VI 1 1-5-1 949, Richard Boettcher. (Collection of David Shap- pirio.) Will be deposited at Museum of Comparative Zoology at Harvard University. This species is nearest to A. reynoldsi Banks, but differs in a number of characters as given in the following key. It seems strange that new species should turn up in sections as well covered by collectors as Washington, D. C., as I have two more new species from there. Key to tJic Females oj the Genus Alasagenia Banks 1. Body entirely red or yellowish, with the wings light yellow with the tip blackish reynoldsi (Banks) 1 .

All these species have the characters as given in the descrip- tion of the genus, including the beard of long hair on the mentum. 72 ENTOMOLOGICAL NEWS [Mar., '50 Further Corrections and Additions to the Clemson, South Carolina, List of Scarabaeidae (Coleoptera) By O. L. CARTWRIGHT, United States National Museum In the past ten years eight more species have been added to the Clemson list of Scarabaeidae (ENTOMOLOGICAL NEWS, XLY, 1934, pp. 237-240, 268-269; L, 1939, pp. 284-286). Since it is unlikely the writer will have an opportunity for future col- lecting in this restricted area, these additions are presented below and the list probably closed so far as he is concerned. Determinations of the two unnamed species of Trox in the original list are included. A few corrections are also given. The total number of Scarabaeidae collected at Clemson stands at 169 species and varieties in 52 genera. Additions : Canthon lact'is (Drury) 30 March 1944, one in flood debris. Ataenius cyliiidrus Horn 9 May, 13 July, 17 Aug., 14 Sept. Ataenius miamii Cartw. 7 May, 7 July, 14, 30 Aug. Dialytcs striatulus (Say) 30 August 1940, one in flood debris.

Ixi, '50] ENTOMOLOGICAL NEWS 73 Current Entomological Literature COMPILED BY RAYMOND Q. BLISS AND R. G. SCHMIEDER. Under the above head it is intended to note papers received at the Academy of Natural Sciences of Philadelphia and the University of Pennsylvania, pertaining to the Entomology of the Americas (North and South), including Arachnida and Myriopoda. Articles irrele- vant to American entomology will not be noted; but contributions to anatomy, physiology and embryology of insects, however, whether relating to American or exotic species will be recorded. This list gives references of the year 1950 unless otherwise noted. Continued papers, with few exceptions, are recorded only at their first installment. For other records of general literature and for economic literature, see the Bibliog- raphy of Agriculture, Washington, and the Review of Applied Entomology, Series A, London. For records of papers on medical entomology see Review of Applied Entomology, Series B. NOTE: The figures within brackets [ ] refer to the journal in which the paper ap- peared, as numbered in the List of periodicals and serials published in our January and June issues. The number of the volume, and in some cases, the part, heft, &c. is followed by a colon (:). References to papers containing new forms or names not so stated in titles are followed by (*); if containing keys are followed by (k); papers pertaining ex- clusively to Neotropical species, and not so indicated in the title, have the symbol (S).

This important volume by Dr. Bates, which was awaited with expectancy by many of those interested in mosquito biologies, brings together much of the published information concerning these insects. It is a work that should prove useful not only to all entomologists but also to those interested in other aspects of natural history as it draws widely on many fields of biological science. The introductory portion is especially valuable as it deals in biological generalities, and in addition points out where progress has been made and also to those aspects that have been appar- ently overlooked or not investigated. The following statements are certainly warranted : "Even with all of the work that has been done on mosquitoes, the final impression of such a review is that a great deal more work is needed before we can achieve any real understanding of mosquito behavior." "Perhaps the greatest gap in our general knowledge of mosquitoes lies in the field of genetics. . . ." The use of the term natural history for the studies of the habits of these insects is to be commended and the reviewer thoroughly agrees with the author in his unwillingness to be "handicapped by an organization of science in which field studies are filed in the pigeonhole 'ecology* and laboratory studies in the pigeonhole 'physiology.' ' A major portion of the book deals with the relation between the various stages of the mosquito, during its life cycle, with its environment. \Yith the amount that has been published and with the enormous number of titles in serial and special works in which this information lias appeared the task is one that 82 ENTOMOLOGICAL NEWS [Mar., '50 would not be attempted by an individual easily discouraged. The information discussed in some detail includes not only a good deal of the author's and his associates' work but the out- standing information gathered by others. The bibliography is not all that one might desire, and the author apologizes for its incompleteness, but, nevertheless, most of the more important works are listed. Such omissions as may be noted are usually not of great importance, but it does appear that the discussion of autogeny could have been considered in more detail. The chapter on the classification of larval habitats is interest- ing, but it would appear that practically any such classification will be modified by those working in the field so as to best serve the local situation. The discussion of mosquitoes in relation to other organisms as parasites, prey, hosts or vectors is an effective presentation of these relationships which make this family of insects so im- portant to man. A separate chapter on mosquitoes as vectors of viruses is an interesting summary of our information con- cerning the development and transmission of this group of pathogens. The discussion of malaria is relatively concise, as this particular aspect is such a highly developed and extensively studied field that a whole volume could easily be devoted to it. In addition the author was probably aware that in the recently published Malariology by Boyd (Saunders) there would be discussions of these relationships at a much greater length, than would be possible in the present book. The short discussion of some of the more interesting species complexes in the mosquitoes is of value, but any attempt to discuss the mysteries involved in such a limited space is more tantalizing than informative. Summaries of the classification and the distribution of mos- quitoes are included and serve a useful purpose in the scheme of the book. Unfortunately the limited method of treatment means that many will have to refer to original discussions in- stead of being able to answer their questions by consulting the text. The appendix has a systematic list of mosquito species, but with its incompleteness it is liable to be of less value than the author contemplated. The techniques of mosquito study both in the laboratory and field are outlined, but as these methods are constantly being modified and improvised by many workers the included infor- mation represents only a basic skeleton upon which to build. The concluding chapter on the strategy of mosquito research is an attempt to evaluate some of our knowledge and to point the way for further studies. — J. W. H. REHN. Ixi, '50j ENTOMOLOGICAL NEWS 83 SELECTED INVERTEBRATE TYPES. Edited by F. A. BROWN, JR., Chairman, Biological Science Department, Northwestern University. Contributors: William Balamuth, Frank A. Brown, Jr., John B. Buck, William D. Burbanck, Chauncey G. Good- child, Libbie H. Hyman, Margaret L. Keister, Lewis H. Klein- holz, John H. Lochhead, Madelene E. Pierce, \V. Malcolm Reid, Mary D. Rogick, Talbot H. Waterman, 597 pages. 235 illus. 6 by 9y4. Cloth $6.00. The dependence of American teachers of invertebrate zoology upon European texts or upon inadequate American ones, has been partially resolved by the appearance of this book. The book is primarily a laboratory manual, but can be used by teachers of invertebrate zoology as a text supplemented by the more generalized lectures. Representative species belonging to the major phyla and to many of the minor ones, are described in varying detail. The phyla, and in some instances, lesser systematic categories, are dealt with by one or more of the contributors. Thus, in the case of the arthropods, the Xiphosura and Crustacea are pre- sented by J. H. Lochhead ; the myriapods, insects and arachnids, by J. B. Buck and M. L. Keister. Some of the contributors have written their sections as morphological accounts, while others have largely devoted their writing to laboratory instruc- tions for the study of the animals. Thus, all sections are not equally informative, and in some instances, the mixture of de- scription and instructions for the disection makes it difficult to follow either. In many cases, brief directions for elementary physiological experiments are given as well as notes on the embryology and life history of the species which is described. Periplaucta auicricana was selected for the insect type and twenty pages (pp. 475-495 ) of description and laboratory direc- tions with four figures are devoted to it. A page comparing P. anicricana and Blaberus cranii\cr is appended to the descrip- tion. An additional eight pages including one full page plate is utilized for the description of the larva of Drosophila inclano- gastcr. The phyla Coelenterata, Annelida, Arthropoda, and Echino- dermata are well written and comprehensive. The other major metazoan phylum, i.e., Mollusca, is not as well handled, and in many places becomes verv elementary in approach. It is dis- appointing to see the words "liver" and "hepatopancreas" still being used in descriptions of molluscs. This book will prove to be a great aid to teachers of general zoology as well as to those teaching invertebrate zoology.— NATHAN W. RISKR.

INC., Lancaster. Pa. JUL 2 5 1950 JAMES A. G. REHN ENTOMOLOGICAL HEWS VOL. LXI JULY, 1950 No. 4 James A. G. Rehn Completes Fifty Years of Research The members of the American Entomological Society have taken a great deal of pleasure in commemorating this year the fifty years of service of one of its oldest and best friends. On June 1, 1900, Mr. James A. G. Rehn joined the staff of the Academy of Natural Sciences of Philadelphia. Although he became a resident member of our entomological society only in 1910, he was an Associate in the Entomological Section of the Academy from almost the same date that he joined the Academy staff. As the Society and the Section were practically synony- mous, his services to the Society were virtually in effect since the turn of the century. In this age of dashing about from one occupation to another, it is gratifying to find a man who decided early in life what he wished to do and who gained an abounding enthusiasm for it which he was able to maintain undiminished for fifty years. Mr. Rehn came to work at the Academy when he was about nineteen years old. In the intervening years he has attained an enviable reputation as one of the world's outstanding orthopterists, and at the same time has served the institution for which he works in many important ways. He has labored successively at the Academy as Assistant Curator; Associate Curator of Insects; and since 1933 as Curator in that department. He has also served as Recording Secretary, Secretary, Secretary of the Council and of the Hoard of Trustees, and at the present time is Corresponding Secretary. In the latter position he has main- tained contact with many of the world's best-known natural scientists. (85) 86 ENTOMOLOGICAL NEWS [Juty, '50 In the American Entomological Society, Mr. Rehn's activities have been just as constant and varied. For many years he has constantly played some vital role in the conduct of its affairs, having acted at various times as Vice-president, President, Edi- tor of the Transactions, and currently as Treasurer of the or- ganization. The very extensive insect collections of the Society and of the Academy are in his charge, and for a long period he has aided visiting entomologists who have come in large numbers to examine insect material. He has also done the many and varied chores which fall to the lot of the Curator of an impor- tant department. Aside from Mr. Rehn's services at the two Philadelphia insti- tutions, he has been active in many other organizations. He is a fellow and past president of the Entomological Society of America; a charter member of the Society of Mammalogists and of the Society for the Study of Evolution ; a member of the Society of Systematic Zoologists and of the Society of Sigma Xi ; a fellow of the American Geographical Society and of the Ameri- can Association for the Advancement of Science ; and a fellow and past-president of the Delaware Valley Ornithological Club. During the first World War he served with the Military Intelli- gence Division of the U. S. Army, Counter-espionage control. His contributions to scientific literature have been very ex- tensive. Mr. Rehn entered the field of natural science at a period when the old-fashioned naturalist was just about to be- come extinct; when taxonomists were just entering into the higher and more glorified status of specialists. However, there still remained a remnant of the idea that breadth of knowledge in a general field was a wholesome virtue. Thus we see re- flected in his earlier activities, and to some extent in his writing, a greater diversity in subject matter than is often encountered today. His sixteen earlier publications in Mammalogy, and four as joint author, illustrate this point. The order Orthoptera has, however, been his main interest in later years, and about 227 papers stand to his personal credit in this field. In addition, 41 were published jointly with Morgan Hebard and 15 with his son, [ohn W. H. Rehn. This mass of published data places him Ixi, '50] ENTOMOLOGICAL NEWS 87 among the half dozen most productive scientific writers on the Academy staff in the nearly 140 years of its history. No other entomologist who has been a member of this Society has ever achieved this record. At present Mr. Rehn is engaged — at the request of the Aus- tralian government — in the preparation of a comprehensive work on the grasshoppers of Australia. Two volumes, of a possible five or six, are partially completed. Over a period of many years he has worked on the accumula- tion of material for a monograph on the Orthoptera of North America. In this work he has been assisted chiefly by Morgan Hebard and by his son, John W. H. Rehn. The work is expected to occupy about four volumes of 500 or more pages each. For a period of over 45 years Mr. Rehn, alone or with his coworkers, has covered most of the United States in a series of many col- lecting expeditions. Outside the United States similar expeditions have been numerous, including trips to Africa, Colombia, Costa Rica, Hon- duras and Brazil. Largely through his efforts, and those of Morgan Hebard, a collection of Orthoptera has been built at the Academy which now exceeds half a million specimens — the finest in the world. At its last Spring meeting, on May 25, the American Ento- mological Society devoted its session to a commemoration of Mr. Rehn's 50 years of service. Many friends and their wives were present. A gift was presented by members in appreciation of his work for the Society. On June 1 the Academy of Natural Sciences called a meeting in its library, of staff members and friends of Mr. Rehn, this being the exact 50-year anniversary of his first official connec- tion with the institution. An engrossed resolution from the Board of Trustees of the Academy was presented by its presi- dent, Mr. Charles M. B. Cadwalader. The text of this resolu- tion is reproduced below. "\Vhereas Mr. James A. G. Rehn, Curator of Insects of the Academy of Natural Sciences of Philadelphia, on June 1, 1950, 88 ENTOMOLOGICAL NEWS | [illy, '50 will have served the Academy as a member of the staff for fifty years and, "Whereas Mr. Rehn's scientific attainments expressed in his important research, many publications, collections and expedi- tions have been recognized by the scientific world, thus bringing honor and distinction to the institution, "Be it resolved by the Board of Trustees of the Academy of Natural Sciences of Philadelphia that the gratitude and appre- ciation of the Academy be made a permanent part of the records of this institution by being included in the official minutes, and further be it resolved that the Secretary is instructed to transmit to Mr. Rehn a copy of this resolution." (Signed by the President and Managing Director.) The members of the American Entomological Society and Mr. Rehn's many friends wish him long added years of satisfying work. M. E. P. Notice Due to circumstances beyond the control of the editor and of the Society, ENTOMOLOGICAL NEWS has been far behind schedule for a number of years. In order to correct this condition it was decided, with the permission of the Post Office Department, to omit the April, May and June numbers from the current volume, so that the present (July) number will actually appear during its proper month. This July number will then be followed by the usual October, November and December numbers. Al- though Volume 61 will therefore consist of only seven separate issues rather than the usual ten, we hope to be able to increase the size of these issues in order that the completed volume will approximate normal size.

In addition to records given by Vogt, specimens have been collected on living capote (Diospyros te.rana Scheele ) as far west as Pecos River in Val Verde Co., Texas. As pointed out by Vogt, it breeds in healthy capote and living trees in that section show many adult emergence holes. In parts of Texas this tree is frequently allowed to remain along highways for ornamental purposes. * Contribution from Department of Zoology and Entomology. 90 ENTOMOLOGICAL NEWS [July, '50 Agrilus geronimoi n. sp. $.

Two more specimens of this species convince me that it is distinct from floridaniis Lee. and is of specific rank. It is shorter, elytral costae less evident and pubescence of pronotum red instead of yellow as in floridaniis. A female specimen was collected in Davis Mountains, Texas, July 3, 1940, by D. J. and J.

DREISBACH, Midland, Michigan Banks ( 1 ) erected the genus Lissagenia for two South Ameri- can species which he described as new at the time, L. flampennis, L. insignis, and he also included the species Priocnemella dij- fortnis Banks. He designated the species L. flavipennis as the genotype. This genus, like Alasagenia, has a beard of hairs on the mentum which are quite long and which bend forward slightly, but it differs from that genus mainly by the absence of small teeth on the posterior tibiae, but has instead, a row of very small spines on the apical half or more of the dorsal surface and a row on each side. There are three other characters which also separate it from Alasagenia, namely : the posterior tibiae, when seen from behind, are much more sinuous, espe- cially at the base on the outer side, the pronotum is slightly angulate on posterior edge, instead of transverse, the ocelli are in a much smaller triangle, and the lateral are twice as far from the eye margins as they are apart, instead of these distances being about equal. The pronotum is also somewhat flatter than in Alasagenia. Lissagenia hubbelli n. sp. Holot\pc female: Completely black all over, with beautiful golden, mat, pubescence, very much like Alasagenia fulgifrons (Cresson except that this pubescence is much denser and covers a much greater part of body), over the whole face, front, vertex, and posterior orbits, slightly less dense on neck, pronotum, mesonotum and scutellum ; all the coxae, more or less, thorax above middle coxae, base of propodeum, the outer, apical corners of propodeum, and the clypeus, with white sericeous hairs; the clypeus much le*ss densely pubescent than the rest of head, trun- cate in front, and with a smooth wide reddish border, a slight reddish tinge to the front edge of clypeus just back of the 94 ENTOMOLOGICAL NEWS [July, '50 smoothed front edge ; clypeus rather long and raised above the mouth parts, slightly raised in the middle, when seen from the side ; the vertex is barely raised above the eye surface, when seen from the side, but the whole front from vertex to antennae is considerably raised above the eyes, increasing in amount from vertex to antennae; when seen from in front the vertex rises perpendicularly for a very short distance at the eyes, the rest of surface flat and entirely raised above eyes ; a few long upright hairs on vertex and front but more numerous and longer ones on and under the clypeus, with a beard of long hairs on mentum ; long white hairs on neck and a few on fore coxae ; ocelli in a high, very small triangle, the fore ocellus slightly more than its diameter from the laterals and these twice as far from eye margins as they are from each other ; comparative lengths of the first four and last antennal joints : 35 : 15 : 60 : 50 : 30 ; antennae very long and slender, longer than the head and thorax ; maxillary palpi slender with five segments, the first short, the second thicker and somewhat club-shaped ; labial palpi, three jointed, thicker and much shorter ; pronotum rather short with a slight angulation in middle of posterior edge, almost flat on dorsal surface ; mesonotum only slightly longer, with a slightly curved dorsal surface, and narrowing from the tegulae to the scutellum where it and the scutellum are only one-half as wide as the width at tegulae ; the propodeum extends in a smooth curve from base to apex, the apical half with fairly broad, low transverse ridges which are stronger on the edges ; a few upright hairs on mesonotum and propodeum ; the wings beautifully marked and very conspicuous ; fore wings with a dark band covering the basal veins and a second broader one covering the marginal, second and third cubital, the apical three-quarters of third discoidal and the basal half of second apical cells, with the tip of fore wings beyond the dark band a deep milky white ; the wings between the bands and basad of the basal band, slightly smoky ; the rear wings hyaline except that the tip beyond the transverse median vein is smoky ; marginal cell large, broader than the second cubital cell and as long as its distance to wing tips ; second cubital cell small, one-half as long as third which is large and extends beyond the marginal Ixi, '50 | ENTOMOLOGICAL NEWS 95 cell ; first recurrent meets the second cubital cell before the middle, and the second recurrent meeting the third cubital cell at the basal two fifths ; basal vein in fore wings slightly basal of the transverse, and the subdiscoidal in rear wings meets the discoidal vein before the origination of the cubitus ; abdomen definitely petioled, the petiole hour-glass shaped, and the ab- domen widest at the apical three-fourths of second tergite from where it tapers to a slender point ; the whole surface covered with a fine, powdery, white, sericeous pubescence, somewhat localized over the surface ; the last tergite covered with the golden pubescence of head, with numerous long whitish or slightly golden hairs on dorsal surface, sides, and the ventral surface ; a deep transverse groove on second ventrite, the seg- ments two to four with a silvery patch of white pubescence at the outer, apical corners ; legs very long, no tarsal comb and no spines on fore femora or tibiae except two small spines on under side of tibiae and a semi-circle of long spines on the dorsal tip ; no spines on the last two pair of femora but these tibiae have a row of small spines on dorsal surface and on the sides ; when seen from behind the posterior tibiae have the outer side incurved at the base ; tarsi with fine spines over the whole surface of the first four joints, all the legs with fairly long spines, beneath, the last pair of all legs with no spines underneath, but only hairs ; claws rather long and with a fairly long tooth at apical third ; ratio of lengths of femora, tibiae, and tarsal joints of hind legs as follows: 40:45:35:15:10:5:7; longer spur of posterior tibiae about one-third length of its metatarsal joint.

GAHAN, Bureau of Entomology and Plant Quarantine, Agricultural Research Administration, United States De- partment of Agriculture, and GEORGE E. WALLACE, Section of Entomology, Carnegie Museum Heniitrichus rufipes was originally described from Sweden. The U. S. National Museum collection contains a female col- lected in the vicinity of Vienna and a male from Boheimkirchen, Austria, both identified by F. Ruschka ; also 2 females collected by J. Fahringer in the vicinity of Vienna, and 1 female from Angern, Austria, sent in by H. L. Parker and identified by Ixi, '50] ENTOMOLOGICAL NEWS 97 Gahan by comparing with the Ruschka determined material and with Thomson's description. The last-mentioned specimen bears a label " ? Ex Bruchus," indicating a doubtful host record. Nothing further is known concerning hosts and distribution of the species in Europe. Occurrence of the species in America was recorded in a note by the junior author published in 1949. The specimens upon which this record was based were collected in Pittsburgh, Pa., and were identified by comparing them with the above-men- tioned European material. Subsequently, while examining some pteromalids from the collection of the Natural History Survey of Illinois, specimens collected by Wm. A. Nason at Algonquin, 111., in 1896 were recognized as being H. rufipes. Further investigation revealed that in 1896 Ashmead had de- scribed what he supposed to be a new genus and new species, Uriella rufipcs Ashm., based in part upon a series of specimens having the same origin and data as those just mentioned. The actual holotype of Uriella rufipes Ashmead, as recorded in the type catalog of the U. S. National Museum, is the specimen mentioned in the description as having been bred by F. M. Webster from Botis erectalis Grote, and is from Ohio. The host label on this specimen bears a question mark, indicating that the host association was uncertain. This holotype and the eight paratypes collected by Nason are all alike and appear to be identical in every way with the European material of Hcuii- tric Juts rufipcs Thorn. The genus Uriella Ashmead must there- fore be considered a synonym of Hernitrichits Thomson and the species rufipcs Ashmead a synonym of rufipcs Thomson. Two other occurrences of H. rufipes remain to be mentioned. One specimen, received from R. R. Driesbach, is labeled as having come from a "pine cone gall" on Sali.r sp. collected in Elizabeth County, Michigan, Sept. 11, 1937. The other record concerns several specimens received for identification from L. C. Kuitert and which were taken by him in Morris County, Kansas, in April 1948 in association with Ptinns hirtellns Sturm and Orysaephilus surinamensis (L.) infesting pack-rat drop- pings. Prof. Kuitert has published an account of his observa- 98 ENTOMOLOGICAL NEWS [/"ty. '50 tions on this association in The Florida Entomologist, vol. 33, p. 177, 1949. It is evident from these records that H. rufipes is a widely distributed species. Its real host relationships are not clear. The fact that the host associations listed (some of them as doubtful) include Lepidoptera, Diptera, and Coleoptera would seem to indicate a likelihood that some of these records are wrong. Kurdjumov (Revue Russe d'Entomologie, vol. 13, pp. 3, 4; 1913) placed Uriella Ashm. in synonymy with Phaenacra Foerster. Cotypes of Phaenacra nubigera Foerst. (the geno- type species) are in the U. S. National Museum, and although they superficially resemble the genotype of Uriella, the two genera are not closely related. Phaenacra belongs to the tribe Merisini and is believed not to be separable from Merisus Walker. Hemitrichus ( = Uriella} belongs in the tribe Metastenini. Hemitrichus rufipes is easily recognized in both sexes by the following characters : The clypeus is perfectly smooth and shin- ing with a sharp median tooth on its anterior margin ; the parapsidal grooves are almost entirely effaced ; the propodeum is strongly and nearly uniformly punctate and without either a median carina or lateral folds ; the marginal vein is distinctly swollen at base ; the posterior tibia has two distinct spurs ; the abdomen of the female is conic-ovate with the first tergite per- fectly smooth, the others weakly reticulated but shining, the ovipositor sheaths shortly exserted. The color in both sexes is aeneous black, with the scape pedicel and all legs (except their coxae) bright reddish testaceous.

Pennsylvania j Professor R. K. Enclers kindly collected for me ants on Saipan during the summer of 1949 while he was engaged in mammal studies for the Pacific Science Board under the aus- pices of the Office of Naval Research. These ants were princi- pally those species coming to his mammal skinning tables and therefore represent a sampling of the scavenging, adaptable species. The records are also of interest in representing one of the far-flung Pacific Islands, comparatively few of which have been explored from an entomological point of view until recent years. From Guam, -some 125 miles south southwest, Wheeler (1912) listed 21 species of ants. From Bikini Atoll, about 1200 miles east, Cole (1949) enumerates 13 species taken in 1947. There are doubtless numerous collections made in the 1940's whose records are not presently available from this and other islands of the area. The ants of these three islands reflect the general nature of ant distribution in the Pacific. Each contains tropicopolitan species as the chief element of the fauna. All three contain the large Odoutoniachns Jiaeinatoda, the sole tropicopolitan species of the primitive ant subfamily, the Ponerinae, although a second species taken by Dr. F.nders may represent another ponerine 100 ENTOMOLOGICAL NEWS [Juty. '50 becoming tropicopolitan. Each has two tiny species of Mono- morium (destructor and floricola) of the subfamily Myrmicinae. Bikini has a third species of this genus, pharaonis, which has a greater distribution than the other two since it is adapted to life in heated apartment houses extending to the very center of the United States while the others are tropical or subtropical. The myrmicine, Solenopsis geminata ruja, widespread in the Pacific, is present on Saipan and Guam but absent from Bikini ; gemi- nata itself is neotropical and spreading. Saipan and Guam have the myrmicine, Tetramorimn guineense, with the genus repre- sented on Bikini by another tropicopolitan species of the genus, simillimum, whose original home was probably Africa. T a pi- no ma niclanocephalum, a tiny and widespread member of the Dolichoderinae, occurs on all three islands as does the world- wide and ubiquitous formicine, Paratre china longicornis, along with Nylanderia bourbonica. the latter being paleotropical. Cainponotus rcticnlatus subspecies and C. chloroticus, present on Guam and Bikini but absent from the Saipan collection, did not come to the skinning tables though other species of the genus (as inaculatus} do so in other tropical areas. None of the lists contains a clear-cut endemic species. Wheeler, however, described a new variety and a subspecies of widespread species from Guam. The Saipan ants and their distribution are given below. 1. Lcptogcnys (Leptogenys) nia.viUosa (F. Smith) A species evidently becoming tropicopolitan since known from a number of islands in the Indian Ocean, from South Africa, the Anglo-Egyptian Sudan and several of the West Indian islands. A worker which I took in Cuba of the subspecies falcata Roger differs chiefly in having the anterior clypeal mar- gin angulate instead of convex. Arnold's figure of the South African form also shows the clypeal margin angulate although my Sudan specimens have this part convex as in the Saipan ants. The ants are predatory, quick in their movements and sting painfully. Ixi, '50) ENTOMOLOGICAL NEWS 101 2. Odontomachus hacmatoda (L.) Tropicopolitan ; large, dark brown and stinging painfully ; generally carnivorous. 3. Phcidolc, near rinae tipuna Forel Although Wheeler recorded P. javana Mayr from Guam, the present species in the soldier caste is much smaller and less glabrous. It is also much smaller than oceanica and bolabo- lensis. The Saipan soldier is close to rinae subsp. tipuna Forel but has a distinctly shorter head and is also close to the rinae subsp. incensa Wheeler types in the American Museum of Nat- ural History. 4. Phcidolc sp. Workers of a second species, impossible of identification with- out the soldier caste, differ in being smooth, shiny and dark rather than being densely punctate and pale. 5. Cardiocondyla cineryi Forel One dealate female of this cosmopolitan species. 6. Vollenhovia pedestris F. Smith Not in the Guam or Bikini lists. The workers agree well with Mann's British Solomon specimens; subspecies are known from New Guinea, the Seychelles, Borneo, the Philippines and other paleotropical localities. 7. Mononwrium destructor (Jerdon) Tropicopolitan ; tiny and reddish yellow. 8. Mononwriiini floricola (Jerdon) Tropicopolitan ; even smaller than the preceding and a shiny dark brown in color. 9. Solcnopsis t/cniinata subspecies ruja (Jerdon) Showing the mesosternal spine characteristic of this wide- spread paleotropical form of the cosmopolitan species. I have 102 ENTOMOLOGICAL NEWS [July, '50 this also from the island of Samar, Philippines (U.S.N.). Safford (1905) says of this form on Guam that "these little creatures when out on foraging expeditions, travel in lines and sting every animal that crosses their path. Sometimes young chickens are killed by them. They are common in houses, and it is not unusual on turning in at night to find a line of them crossing the bed." I have observed similar habits in the typical neotropical form. 10. Tetramorium guineense (Fabr.) A common tropicopolitan species with generalized habits. 11. Tapinoma melanocephalum (Fabr.) Tropicopolitan and a house pest where it often feeds on greasy substances. 12. Technomyrmes albipcs F. Smith? One worker with gaster and petiole missing may well be this paleotropical species. 13.

College of Texas During the course of a study on the Meloidae of Texas, the following new species from Arizona was found among a lot of material received from the museum of the University of Michi- gan. Up to the present time, E. ochrea LeConte was the sole representative of the genus Epicauta in North America which possessed moniliform antennae and the form described here is of particular interest in sharing this character. The secondary sexual structures are likewise shared by the males of the two species. The author is indebted to Dr. Theodore H. Hubbell, Curator of Insects at the Museum of Zoology of the University of Michigan, for his kindness in loaning the specimens. Epicauta moniliformis n. sp. Fuscous, shining, sparsely covered with cinereous pubescence. Elytra yellow-testaceous or ferruginous-cinereous, with very indistinct scutellar and humeral maculae. Abdominal sternites in part ferruginous. Entire upper surface minutely alutaceous and rather densely, finely punctate. Head rounded from vertex to eyes, one-fifth wider than long ; eyes large, one and one-half times as long as interocular width, two-thirds wider than infraocular area ; an- tennal callosities slightly prominent, glabrous. Pronotum nar- rowly campanuliform, as long as wide, one-seventh narrower than head ; disk witli a deep median sulcus not reaching apex, basal impression shallow, transverse. Protibiae with a single robust spur in male ; mesotibial spurs rather short, acute ; meta- tibial spurs acute, tapering, slightly concave on inner face, the inner spur distinctly longer. Protarsi in male with first seg- ment short, contorted, and toothed. Antennae short, scarcely surpassing base of elytra, nearly uniform in thickness, segment^ from second moniliform ; scape strongly arcuate, thickened api- cally, in male attaining hind margin of eye, in female scarcely 104 ENTOMOLOGICAL NEWS [Juty, '50 attaining middle of eye ; second segment as long as third ; third about one-fourth as long as first in male, two-fifths as long in female ; rest subequal, feebly shorter than third. Length 11-12 mm. Holotype male and allotype female : Palmerlee, ARIZONA, July 11 (H. A. Kaeber) [University of Michigan]. Remarks : This species has moniliform antennae as found in E. ochrea (LeConte), to which species it is quite closely allied. From ochrea it is distinct in having the scape reaching just to the hind margin of eye in male, not beyond it, and in female likewise shorter, not attaining middle of eye. In addition, the entire body is fuscous, except the elytra, which are ferruginous, and the body form is much more slender. Zethus, Pachodynerus and other Southern Wasps from Massachusetts (Hymenoptera : Vespoidea; Sphecoidea) By KENNETH W. COOPER, Department of Biology, Princeton University On the old Fay estate at Woods Hole, Cape Cod, Massachu- setts, standing in an open field near the margins of a predomi- nantly beech-black oak woods, there is a single, compact, large clump of a cultivated grape ("Vitis timer ophylla," according to the gardner) that blooms late in the season. Its flowers prove very attractive to aculeate wasps in early August, and on August 7, 1948, Dr. Jean Pasteels, of the Universite Libre de Bruxelles, and myself made a noteworthy capture of three female speci- mens of typical Zethus (Zethuscnlus} spinipes (Say). This is believed to be the northernmost record so far published for the species, and the first record of its occurrence in Massachusetts. Dr. J. C. Bequaert, of Harvard University, has a specimen from Buttenwood, Rhode Island. It is known from two Long Island records in New York, and has also been found only rarely in New Jersey. Although by no means a very uncommon wasp in the South, it is definitely a rarity in New England. The Ixi, '50 | ENTOMOLOGICAL NEWS 105 capture of three specimens at Woods Hole, along with Dr. Bequaert's recent unpublished record from Rhode Island, makes it very likely that it is a native in New England, and not an infrequent visitor. The grape remained in flower only until August 10th, hut no additional Zethus were seen. August 8th a very striking and wholly unfamiliar red eumenid (at first mistaken for a Ryg- chium) was taken at the grape blossoms and subsequently iden- tified by Dr. Bequaert to be Pachodynerus erynnis (Lepel.). Originally described from the "Carolinas," P. erynnis is most commonly taken in Florida. Its known range extends west to Louisiana and north to Georgia. Whether or not the Woods Hole specimen was an accidental introduction onto the Cape can only be surmised. Probably it was, but it should be pointed out that quite a number of wasps, including Zethus, more char- acteristic of southerly climes, live in the sand and pine coastal strip along the southern Cape. For example, among others, Ardchnophroctonus jerniginens (Say), Batasonus interruptus (Say), Pompilioidcs aniericanus (Pal. de Beauv.), Pseudo- methoca geryon (Fox), Ps. similliuia (Sm.), Ps. sanbormi (Blake), E phut a puteola (Blake), Campsomeris quadriuiacu- lata (Fab.), Notogonidea argentata (Pal. de Beauv.), Prio- nonyx bijovcolatum (Tasch.), Isodontia anripes Fern., and Alyson melleus Say, have all been collected by me at Woods Hole. On this score, C. W. Johnson (1930, Pub. Nantucket Maria Mitchell Assoc., vol. 3) has briefly commented on insects and plants whose normal ranges extend from Georgia and Florida coastwise to Nantucket and even farther to the North. In addition to the Zethus and Pachodynerus, the following vespids were also attending the grape: Enmcncs jraternus Say, Odynerus (Rygchium} rugosum Sauss., O. (R.~) leucomelas Sauss., O. (/?.) hidalgo var. boreo-orientalis ]. Beq., 0. (R.} boscii Lepel., Ancistrocerus birenimaculatus (Sauss.), A. nni- jasciatus (Sauss.), Monobia qnadridens (L.), Vcspa (Vespuhn arenaria Fab., and Polistes juscatus (Fab.). One male of Mo- uohia had a female stylopid exserted between the fourth and fifth abdominal tergites of the left side. 106 ENTOMOLOGICAL NEWS [July, '50 Arthropods of Possible Medical Significance Collected in Terrell County, Texas By R. B. EADS and B. G. HIGHTOWER, State Department of Health, Austin, Texas With the Big Bend National Park of Texas rapidly becom- ing a major tourist attraction, this Department is endeavoring to obtain fairly complete information relative to the medically important anthropods in the area. Consequently, we were greatly appreciative of the opportunity presented the junior author to accompany Dr. W. Frank Blair, University of Texas Mammalogist, and his students on a field trip to West Texas (Terrell County) June 6 to July 8, 1949. The majority of the mammals collected were examined for ectoparasites. An unexpectedly light mammal population was encountered and the small number of rodents seen were sup- porting, for the most part, small or no ectoparasite infestations. Some attention was directed toward the collection of arthro- pods other than ectoparasites. The taxonomic status of this material has been determined and is presented here.

Ixi, '50 J ENTOMOLOGICAL NEWS 115 Review of Straub's Work on Odonata Among papers of European publication received within the last two years, one of the most noteworthy is that by Eberhard Straub, from the Zoological Institute of the University of Bonn, entitled STADIEN UNO DARMKANAL DER ODONATEN IN META- MORPHOSE UND HAUTUNG, SOWIE DIE BEDEUTUNG DES SCHLUP- FAKTES FUR DIE SYSTEM ATiscHE BiOLOGiE (Stages and alimen- tary canal of the odonata in metamorphosis and moulting, as well as the significance of the act of transformation for systematic biology). It appeared in the Archiv fiir Naturgeschichte, N. F., Bd. 12, Heft 1, Leipzig, 1943, pp. 1-93, 12 tables, 13 figs., 1 pi. Its scope may be perceived from its table of contents (trans- lated) : I. Introduction. II. Fundamentals, A. Material, B. Technique, C. General terms, D. Special object: Aeschna cyanea Miiller. III. Moulting and transformation stages: A.

Systematic-biological results of the study of transformation. IX. Summary. Ab- breviation list. List of literature. These researches began at Basle, at the incitation of Prof. A. Portmann and were based on 18 species, belonging to 7 families. The localities in Switzerland for the species are given with sug- gestions for the transport and rearing of living larvae and images. The author believes that the greatest exactness and reliability in dealing with the developmental stages is to be attained by the determination of a fixed point in the middle of the transforma- tion period. This ideal fixed point he found in a withdrawal 116 ENTOMOLOGICAL NEWS [July, '50 stage of the labium. He chose as zero the moment, in the middle of that period, when the imaginal labium has been withdrawn to one-half the length of the lateral margin of the larval labium, as shown at Me1/? in fig. 13f (following page 82). From 0 out he designates the days with arabic numerals. After 0 they bear positive signs, before 0 negative signs. The method is il- lustrated in two elaborate tables : 1 1 . External course of meta- morphosis of Ac. cyanca, following page 82, and 12, Meta- morphosis of the gut of Ac. cyanca, anatomical findings, follow- ing page 84. The author's rearing normal is determined by a tolerably constant room temperature of about 20 C., sunlight excluded, and optimal food intensity. Under these conditions, eight larvae of cyanca went through the last instar in 28 days (range 26- 30)." The morphology of the eye region, its changes and homologies are treated on pp. 20-23, the wing rudiments and the labium pp. 23-27, caudal appendages and abdominal processes pp. 27-29. As a result of experimental feeding he determined that in no case did larvae of cyanca seize Tubifex worms after stage -- 4% .days. The earliest respiration through the spiracles occurred at - % day. Reduction of locomotion by expulsion of water from the rectum ("Riickstossschwimmen") took place at stage + li/4 days at the earliest, but complete cessation not before + 1 % ; about 1 y± days before the appearance of the imago the larva has completely lost this peculiar faculty. The author's histological finds of his study of the transforming gut, tracheae and transverse muscles are promised for a later paper. The terminology of the tracheal trunks employed by authors from Reaumur, 1742, to the present work is shown in Table 3, page 43. The metamorphosis of the rectal tracheae is described in detail, pp. 48-52. Tillyard's terminology of the rectal gills is discussed ; his terms simplex and duplex systems, holobranch and hemibranch, are rejected but his undulate, im- plicate, foliate and lamellate types are retained, pp. 52-54, 77. The period from the cessation of food intake to the last (trans- formation) moult is designated as the chief metamorphosis Ixi, '50] ENTOMOLOGICAL NEWS 117 C'Hauptmetamorphose") ; in the laboratory it occupied nine days, on an average, in cyanea; in this period the chief trans- formation processes occur. Preceding the chief metamorphosis is a premetamorphosis from about stage - - 12, the beginning of larval degeneration. Following the chief metamorphosis is the postmetamorphosis in which the rectal tracheae and some ab- dominal muscles break down. Table 5, page 64, gives a list of the destructive processes in the larval organs of cyanea by stages. Some changes in Odonate metamorphosis, especially in the Li- bellulinae, approach those of holometabolic insects, pp. 65-66. Details of transformation of 12 species of European Odonata form Table 8, page 69. Four types of transformation are rec- ognized and illustrated by outline drawings, pp. 70-72 : 1 . Aeschna type, head hanging down, followed by an upswing, transformation position "c" * (Ae. cyanea, Cordulcgaster an- nulatus, Soniatochlora inetaUica] ; 2. Calopteryx type, head hang- ing down, not followed by an upswing, position "c" (Calop- tcry.v) ; 3. Agrion type, head never hanging down, position "b" below the substrate (Lestes viridis, Platycneniis pcnnipes, Agrion pitclla) ; 4. Gomphus type, head never hanging down, position "a"1 above the substrate (Complins pnlchcllus and vitlgatissi- jinis. Onychogouiphns jorcipatns} , pp. 72-78. Table 9, pp. 78- 79, summarizes the results of the author's observations on trans- formation and on moulting by systematic groups and for the Odonata as a whole. Table 10, pp. 80-81, lists the known repre- sentatives of the four types of transformation of Odonata from his own observations and from the literature, while some (e.g., Basiacsclina Janata, Didymops transverse) are inferred from conditions displayed in exuviae, many of which latter he exam- ined in the collection of Dr. Erich Schmidt. The author knows of no cases which can not be referred to one or other of his four types. He adds: The most important result of my researches 1 Position "a" : Standing on a substrate that is horizontal or that is inclined at any angle up to 90° from the horizontal. Position "b" : Hanging from a verticle substrate, or beneath a substrate that is inclined at any angle up to about 60° from the verticle. Position "c" : The same as "b." but the angle may be as great as 90° from the vertical, i.e., horizontal. 118 ENTOMOLOGICAL NEWS [Jul}", '50 on transformation is the emphatically separate position of the Gomphidae. These constitute an exception in every respect. They are the only Odonata which can transform on flat ground and stretch wings and abdomen on the horizontal. The dis- solution of the family Aeschnidae (sensu lato), long ago accepted on morphological grounds, has been supported on biological evi- dence by Portmann (1921). I find this separation confirmed anew by my observations on the act of transformation. PHILIP P. CALVERT Review PORTIER, P., LA BlOLOGIE DES LEPIDOPTERES. 643 pp., 392 figs. Paul Lechevalier, Paris. 1949. (Vol. 23 of Encyclopedic Entomologique.) At the age of 84 the author has given us this lengthy book which on close inspection turns out to be an elementary presen- tation of this one order of insects with emphasis on chemistry and on physiological systems. Anatomical descriptions are lim- ited to what the author considers an indispensible minimum, and classification (including means for making determinations) is omitted. The author aims to present objectively what he con- siders interesting. In the Preface, he deplores the simple enu- meration of facts, and says, "This process permits the accumu- lation of a considerable mass of data in a relatively small space ; it further permits the parading of a great erudition which seems to have been the grand preoccupation of certain savants and in particular of German scholars." In contrast, the present au- thor seeks to duplicate the work on Reaumur, Fabre and Perez in making insects 'live,' and "aspires thus to awaken the love for studying Lepidoptera in the greatest possible number of young Frenchmen." This, the author sets out to do by present- ing an elementary physiology which is limited to data obtained from representatives of this one order. The book is divided into 40 chapters. First, the order is characterized, with a general treatment of insect structure. Then, a chapter on eggs is followed by 18 chapters on the vari- ous functional systems (nutrition, respiration, excretion, etc.) and habits of caterpillars, by 4 chapters on pupae, and by 1 1 chapters on adult butterflies and moths. Finally, 5 chapters are devoted to the action of physical and chemical agents, mimicry. Ixi, '50 | ENTOMOLOGICAL NEWS 119 geographical distribution, edible species, and the teaching of the biology of Lepidoptera. Much detailed information is given including tabular chemical data. Likely some allowance should be made because of the re- stricted communications during the war years, and also for the author's age, but the fact remains that the emphasis is on old data. Most of the work cited is prior to 1930, and very little of the literature of the last decade is mentioned. Unfortunately a large percentage of the references cited in the text are not included in the relatively short bibliography (a common but deplorable habit of numerous French authors), and the illus- trations, being largely copied from standard sources, add little to the literature. \Yhether or not this book will accomplish its objective of awakening young Frenchmen to a love of butterflies, it does have a certain amount of usefulness to entomologists in general. For one reared in the American educational system it is difficult to see any considerable usefulness for the volume. Personally, I would prefer that students seeking elementary treatments take more general works, rather than restrict their notions of physi- ology and ecology to one order of insects, and so get a broader background (ignoring the antiquity of much of the data pre- sented).

THE LANCASTER PRESS, INC., Lancaster, Pa. ENTOMOLOGICAL NEWS VOL. LXI OCTOBER, 1950 No. 5 The Purse-Web Spider, Atypus abbotii (Walcke- naer), with Notes on Related Species. (Arachnida: Atypidae) By SHERMAN C. BISHOP, University of Rochester, Rochester, New York Although some notes on this species were published hy H. C. McCook (Proc. Acad. Nat. Sci. Phila., 40: 203-220, 1888), ad- ditional information has been obtained on details of web struc- ture and on the habits of the males. During the summer of 1947 I was introduced to this species in the field by Dr. H. K. Wallace of the Department of Biology, University of Florida, Gainesville. On June 14th we drove to Sugarfoot Hammock, near Gainesville, and Dr. Wallace pointed out webs within a few feet of the car. We found a dozen or more webs within a fewr minutes and wrere able to collect adults and juveniles of both sexes and examples of the webs. As in other species of the genus, the webs are tube-like structures at- tached at their upper ends, and occasionally at the sides, to the trunks of trees or other suitable supports, and continued beneath the surface of the ground varying distances depending on the size and sex of the spiders. The exposed parts of the webs varied in length from a few inches to approximately 15 inches and in width from about one quarter of an inch in webs of juvenile males to seven eighths of an inch in webs of adult females. Webs of very young spiders were not in evidence. The web of one adult female extended five inches below the surface and twelve inches above, in this instance only 41 per cent below the surface a.s against 60 per cent as reported for the related species, A. bicolor. OCT 2 - 1950 122 ENTOMOLOGICAL NEWS [Oct., '50 by Martin and Katharine Muma (Ent. News, 56(5) : 122-126, 1945). The webs of the males were shorter and more slender than those of the females, as befitting their smaller size. In one instance, the web below the surface of the ground was in two slightly diverging branches. In order to study the construction of the web, four spiders were removed from their burrows and each confined to a tall glass jar containing several inches of moist sand and a slender stick to serve as a support of the web. A small hole punched in the sand at the base of each stick was promptly adopted by the spider as a retreat. Three of the four captive spiders responded the night of June 14th by beginning the construction of webs. The web of the largest specimen (Fig. 1), a juvenile male, was 1% inches long on the morning of the 15th. On the morning of the 16th the web was 3 inches long and the basal two-thirds had a coating of sand derived from widening and deepening the hole. The web was lengthened to 3% inches by the 17th. There was little further evidence of activity until June 19th when the web measured 4 inches in length. A small pile of sand at the base of the tube indicated that the hole had again been deepened and that the sand had been carried up within the tube and dropped from the opening at the top (fig. 1). There was no evidence that the sand had been formed into pellets as reported for A. bi- color. Little additional work was done on the web but on July 20th the male, now mature, was found on the surface of the sand and his cast skin on the side of the tube. Another juvenile male, confined on June 14th, emerged from his web during the night of July 3d, left his shed skin on the web and wandered aimlessly on the surface of the sand. A third specimen started the construction of a web but abandoned the ef- fort after a day or two. The fourth specimen, quite possible in- jured during capture, failed to survive. In the field two webs judged to belong to males, because of their slender form and small size, were found to be abandoned. This circumstance and the fact that males in captivity abandoned their tubes upon attaining maturity suggests that the females are sought in their webs for mating. Ixi, '50] ENTOMOLOGICAL NEWS 123 \\ eb of dtypns al'hotii and exuviae of a male 124 ENTOMOLOGICAL NEWS [Oct., '50 The males in life are strikingly colored. The abdomen is ir- ridescent blue, the remaining parts of the body deep black ex- cept for the tips of the tarsi which are light brown. The legs in both sexes are very flexible and appear somewhat inadequate to support the body away from the web. McCook mistakenly identified Atypits niger Hentz [= A. milberti (Walckenaer) ] as identical with A. abbotii and ap- parently did not know A. bicolor which had been described by Lucas (Ann. Ent. Soc. France, 5: 213, 1836). A paper de- scribing the habits of A. tiiger Hentz has been generally over- looked by students of the Atypidae and is not included in the bibliographies of Roewer (Katalog der Araneae, 1942), in Bon- net ( Bibliographia Araneorum, 1945) or in W. J. Gertsch's re- vision of "The Nearctic Atypidae" (Amer. Mus. Novitates, No. 895, 1936). This paper is by W. L. Poteat and was published in the Journal of the Elisha Mitchell Scientific Society (6(2) : 134- 147, 1 pi., 1 fig., 1890). It is an excellent account of what is now known as A. milberti, since no mention is made of the bright red legs which are characteristic of A. bicolor, and since the specimens came from Wake Forest, North Carolina, a locality too far north for A. abbotii. The drawing of the web and shed skin of the male was made by Jon L. Herring. Zoraptera from Georgia In view of the recent article by Valentine and "Wilson (ENTOM. NEWS, 60 (7) : 180, 1949) giving records of the order Zoraptera from Alabama, a small number of these insects in the collection at Eastern Illinois State College seems worthy of note. In March, 1915, Dr. Charles S. Spooner collected seven speci- mens of Zorotypns hubbardi Caudell at Thomasville, Georgia Two of the seven are apterous males, three are apterous females,, and two are dealate females. Apparently this is the first record of the order from Georgia. GARLAND T.

There are three genera of the tribe Dacnusini Nixon that have hairy eyes. This hair may be short, sparse, and visible only at high magnification in strong light. The three genera may be separated by the following key : 1. Cell 2Cu open below (outline of vein gone, though its former position may be indicated by fold in wing membrane and/or some dark pigment) 2 1- Cell 2Cu closed below by a definite vein (not just a fold and/or dark pigment) ; stigma short, wide; labial palps with 4 segments ; females occasionally with abdomen greatly com- pressed and attenuated Cliaeiinsa Haliday. 2. Wing with vein Rs + M&M gone (not just obsolescent), stigma short, wide ; labial palps with 3 segments ; female abdomen short ; gonoforceps of male genitalia not stocking- shaped in lateral view ; second valvifer of female genitalia with large phragma above insertion of ovipositor sheath, and dorsal plate of proctiger firmly fused to ninth tergum Chorcbidclla gen.

Genotype. — Chorebidclla beryl sp. nov. This genus is related to both Chorcbidea Vier. and Chacnusa Hal. It exhibits characters of both genera, and thus seems in some ways to bridge the short gap between them. However, considering the present state of our knowledge of this complex, it seems best to retain the three genera for the time being. Dif- ferences and similarities can be appreciated by studying the above key. As for other characters, the shape of the petiole is nearer to Chorebidca than to Chacnusa, but the rest of the abdomen and the general habitus favors Chaennsa. The male genitalia of Chore- bidclla resemble those of neither genus very closely, though they tend to be more like Chaennsa. The latter differs in having accessory lobes on the gonolaciniae and differently shaped gono- forceps. Chorebidea differs in having extremely elongated gonolaciniae (when viewed ventrally), and peculiar stocking- shaped gonoforceps. The female subgenital plate of Chorcbi- della resembles that of most species of Chacnusa, and the female genitalia in general are definitely closer to Chacnusa than to Chorcbidea.

This species is named in honor of Dr. C. O. Berg, Ohio Wesleyan University. Dr. Berg through his studies of the insect fauna of Potarnogetoii has greatly increased our knowl- edge of the semiaquatic Hymenoptera. Dr. Berg has informed me in correspondence that the only Hydrellia reared from the Aug. 21, 1941, collection from Pot. alpinns was H. ascita. There- fore, we can assume that ascita was the host of the female para- type from Michigan. The series of specimens which I collected in Connecticut were taken with an aspirator from the floating leaves of a water lily (Nyinphaca) and the stems of a sedge. The insects were very active in the bright sunlight of late afternoon, flying around the lily leaves which were heavily mined by fly larvae. None were taken on unmined leaves in shady places. Many other dacnusi- nes and many Hydrellia adults were present. At dusk the para- sites left the lily pads for the sedge stems, where they congre- gated in numbers, all resting head upwards about three inches above the water line. 130 ENTOMOLOGICAL NEWS [Oct., '50 Fertility in Species Crosses in Mosquitoes By JAMES B. KITZMILLER, University of Illinois, Urbana, Illinois The problem of speciation is one that is receiving much at- tention at the present time from systematists and geneticists. One of the points at issue is the interfertility or intersterility of populations which are considered to be species. This note does not presume to take sides on the correctness of the concept of interspecific sterility as a criterion for specific differentiation, but merely reports some experiments which confirm the fact that fertility may exist between populations which are usually re- garded by taxonomists as species. Farid (1949) and Sundararaman (1949) have recently re- ported crosses between two common mosquitoes, Culex pipicns and Culex quinquefasciatus. Weyer (1936) also reports hy- bridization in European forms. These investigators have re- ported fertility in F1; F.,, and back cross generations in crosses between these two species. Experiments conducted in this laboratory support these results and suggest that fertility between these species is not an isolated phenomenon but is perhaps of widespread occurrence. Experiments on the hybridization of these two forms were begun by the author at Fort Knox, Kentucky in 1944. Larvae of Culex pipicns and of Culex quinquefasciatus from Hardin County Kentucky were isolated and hatched. Pipicns X quin- quefasciatus and quinqnejasciatus X pipicns crosses were made, using virgin females for both crosses. Three generations of hybrids were raised (F.,), with no noticeable loss of fertility of viability. These experiments, interrupted by overseas duty, were resumed in February 1948, at the University of Illinois. Stocks of Culex pipiens were collected in Champaign, Illinois and stocks of Culex quinquefasciatus were received from Gal- veston, Texas. The experiments in this laboratory are designed to test the genetic basis for taxonomic differences in mosquito populations. These results will be reported separately, but in the progress of these experiments, crosses between Culex pipicns and Culex Lxi, '50] ENTOMOLOGICAL NEWS 131 quinquefasciatus have been made as a matter of routine, and nothing has been noted to indicate any degree of sterility between the two stocks in this laboratory. The procedure has been to mate several virgin females of one species to males of the other, obtain F: egg rafts, raise these larvae separately, and cross Fa females by Fj males, All F1 individuals are from the same egg rafts. No difficulty has been experienced in obtaining Fx and F., generations. Our results confirm those of Farid and Sundararaman. In view of these facts, it seems that the barrier of interspecific sterility does not exist, at least in our laboratory stocks, between these species. LITERATURE CITED FARID, M. A. 1949.

Ross, Illinois Natural History Survey, Urbana, Illinois In caddisfly material collected in the Philippine Islands by Mr. Harry Hoogstraal in 1946 were two collections of a species of Rhyacophila, a genus not hitherto reported from the Islands. It proved to be quite different from described species from Formosa and other parts of the Oriental region, but to have striking affinities with the Xearctic fauna. The genus Rhyacophila is composed almost entirely of small complexes of one to a few species, the various complexes ex- tremely distinct from each other and frequently difficult to re- late to each other. In North America one such distinctive unit is the Carolina complex, apparently restricted to eastern North 132 ENTOMOLOGICAL NEWS [Oct., '50 America and Puerto Rico, and characterized by the curious shovel-shaped lower portion of the aedeagus. Its closest known relative has been the hyalinata complex, restricted to the western montane region of North America, and possessing sufficient dis- tinctive characters to indicate a fairly remote relationship be- tween the two. Dissection of the Philippine species revealed that it is a much closer relative of the Carolina complex than is the Jivalinata complex, as evidenced by the scoop-shaped aedeagus and double anal plates ; yet at the same time the lateral processes of the scoop in the Philippine species are quite unlike species of the Carolina complex and instead are suggestive of similarly situ- ated processes found in the hyalinata complex. The most logi- cal inference seems to be that all three groups arose from a com- mon and widely distributed ancestor, whose population became fractured into at least three elements, one in the Appalachians, one in the Rockies, and one in the Philippines, each segregate remaining isolated and localized for a great length of time and developing into a distinctive complex.

Ixi, '50] ENTOMOLOGICAL NEWS 135 Biological Notes on Corythucha morrilli O. & D. (Hemiptera: Tingidae) By J. W. TILDEN, San Jose, California This was the only tingid found in association with Baccharis pilnlaris D. C. It is abundant where found but appears to be local in distribution. No reference was found to indicate that any species of Corythucha has been recorded from this plant, but the literature on Tingidae is so extensive that such a refer- ence may have been overlooked. In the original description 1 the authors say that this "is a very common species in the southwestern portion of the United States. We have numerous specimens from Colorado and Arizona." No definite type local- ity nor host plant is given. Since Baccharis pilnlaris is absent from much of this region, it seems evident that this plant is only one of the plants used as a host by this insect, and that it therefore is not host specific on Baccharis. Adults confined in the laboratory Feb. 23, 1947, began at once to feed. Excrement is voided as dark droplets that adhere to the leaves. Feeding punctures cause yellow spots due to the removal of the mesophyll of the leaf, and together with the excre- ment give a characteristic appearance to infested leaves. Feed- ing is in every respect similar to that of other phytophagous Heteroptera. The rostrum is lowered to the leaf surface, the labium bending to allow the stylets to enter the tissue. The stylets are inserted with a sawing motion. Both sexes vibrate from side to side during feeding, and also bob up and down both when feeding and resting. These movements are con- spicuous when many individuals are present on a leaf, but are performed as individual acts, not in unison. Oviposition was noted first on Feb. 26. The ovipositor is dropped downward and forward, being hinged anteriorly and free posteriorly. The leaf is punctured with a rocking motion until the ovipositor is nearly buried in the leaf tissue. The egg is then deposited with considerable effort. \Yithdrawal of the ovipositor appears to require all of the female's strength, and X. H., and C. J. DRAKE, Ohio Journ. Sci., 17, page 298, 1917. 136 ENTOMOLOGICAL NEWS [Oct., '50 is accompanied by repeated tuggings and rocking motions. The blades come free with a sudden jerk and the female braces herself strongly to maintain balance. After the ovipositor is free the female exserts a tubule and deposits a droplet of dark fluid onto the egg puncture, sealing it. This fluid appears to aid in prevention of desiccation. The fluid seems to be of low specific gravity, and flattens out at once, covering an area larger than the puncture. The fluid does not dry completely during the development of the egg, but remains viscous until the egg hatches. This was tested repeatedly by touching the droplets with a fine needle. The egg is flask-shaped, with the micropylar end nearest the puncture. The egg swells considerably, by imbibition of liquids from the plant tissue. The chorion is fragile and the egg soft and easily distorted upon removal from the leaf tissues. It seems likely that this lack of rigidity allows for necessary distor- tion that accompanies the accommodation of the egg to the dimensions of the puncture. Egg laying proceeds rapidly. One female laid fifty-six eggs in four days. Both the upper and lower surfaces of the leaves are used, apparently without preference. Of the fifty-six eggs mentioned above, twenty-seven were on the upper surface and twenty-nine on the lower surface. The lower surface is, how- ever, much more favored by the nymphs. After an egg is laid, the female moves forward a few milli- meters and begins almost at once to feed. This habit of ovi- positing and then feeding causes the eggs to be placed in irregu- lar lines, indicating that the female has oviposited, then fed, then oviposited again, repeatedly. Eggs laid Feb. 26 hatched March 14, after 16 days. Ecdysis was noted on March 17, March 20, and March 28, disclosing the fourth instar. An oversight in feeding caused the death of these nymphs on April 1. Eggs laid March 24 hatched on April 3, ten days later. The shorter hatching time is attributed to the general rise in temperature due to the advance in season. These nymphs molted on April 8, 11, 14 and 16, with adults appearing April 18. This group thus showed stadial times of 5, 3, 3, 2 and 2 days, with 5 instars and a nymphal period of Ixi, '50] ENTOMOLOGICAL NEWS 137 15 days. This together with the hatching period of 10 days gives a life history of 25 days from egg to adult for this reared brood. Eggs obtained from this laboratory-reared generation were reared without any significant variation in life history. It would appear that a species with such a short period of development must produce several generations a year. Plants examined in the field as checks showed that Corythucha morrilli has a long reproductive season and that the species builds up large popula- tions. Adults remained alive in the laboratory for as long as twenty-nine days, continuing to lay eggs throughout this time. Determination is through the kindness of Dr. R. L. Usinger. An Easy Way to Make Entomological Drawings By GEORGE C. STEYSKAL, Grosse He, Michigan Many a worker has shied away from illustrating a part, com- plex genitalia, wing venation, etc., because of lack of artistic skill or a fancied difficulty of drawing objects under the binocu- lar microscope. At its best the camera lucida is cumbersome, especially when used with the binocular. The lighting is criti- cal, the drawing plane must be carefully adjusted and firmly fixed in one position, the size of the drawing is difficult to control, and the instrument is costly. Many workers use another method which obviates all these disadvantages and is possibly even more accurate. This method may be called the ocular grid method since it involves the use of a cross-ruled reticle inserted in one eyepiece of the micro- scope. Such a reticle costs less than ten dollars and a good substitute may even be made at practically no cost by ruling a piece of cellulose acetate or plexiglas or other plastic with very fine lines scratched into the material with a sharp pointed metal tool held in a toolmaker's height gage or laid on a planer gage or gage blocks. The scribing tool is brought alongside the plastic held firmly on a square object so that it may be turned 90°. The scriber and the measuring tool on which it is held 138 ENTOMOLOGICAL NEWS [Oct., '50 are slid across a smooth surface and very light pressure applied to the scriber against the plastic. A convenient distance to space the lines is 0.025 inch. A bacteria counting reticle is also serviceable. The reticle is placed face down inside the eyepiece on a ledge that is provided for the purpose. It provides a screen of fine lines in the field. If the ledge is properly located, the lines should be sharply in focus. If not, try interchanging the top and bottom lenses of the eyepiece — they may have been wrongly assembled after cleaning — or move the ledge to its correct posi- tion. If the latter is not feasible the reticle may be blocked up with bits of plastic cemented around the edge of the reticle. The reticle does not interfere with examination of specimens and may even be left in the ocular if its presence is not found too annoying since it is also convenient for making comparative measurements. The drawing is made on graph paper with an ordinary soft pencil. I use an easily obtainable paper ruled five squares to the inch with pale green lines. The outlines of the object are easy to duplicate by following them through the squares and drawing lines in corresponding squares on the paper. By ruling off sets of two, three or more squares on the paper drawings may be made to various scales. For example, if the object is ten squares long the drawing may be made two inches long (two times five squares) by letting one square of the paper equal one square of the grid, or it may be made four inches long by making four squares of the paper equal one square of the grid and ruling the paper accordingly. To transfer the drawing to the paper on which the final ink drawing is to be made (I use three-ply Strathmoor bristol board ) , I blacken the back of the graph paper with a very soft lead pencil, such as Eberhard Faber's No. 6325 Ebony, and trace the drawing with the carbon paper thus made onto the bristol board with a mimeograph stylus or a plain nail with the point buffed smooth. If it is desired to reverse a drawing it may be laid face down on the ink board and traced or rubbed from the back. The use of a soft pencil in drawing assists at this point. Ixi, '50] ENTOMOLOGICAL NEWS 139 The drawing may be sketched directly on the bristol board by lightly ruling the board with suitable squares, but I con- sider the use of graph paper more advisable for a number of reasons. Firstly, when the transfer method is used very little erasing is necessary on the ink drawing while unlimited erasing may be done on the graph paper. Secondly, notes may be made on the sketch without worrying about having to remove them. Thirdly, should something happen to the ink drawing another can be made from the sketch on the graph paper. I have made full plate drawings by the method outlined above in three hours. I hope that its use may result in lightening entomological labors and provide more illustrations. Aural Myiasis by Musca vicina (Dipt.) By JOHN W. H. REHN, Academy of Natural Sciences of Philadelphia Many cases of accidental myiasis, including infestations of the ear, due to Musca vicina or M. doincstica have been recorded. However, in most recorded instances it appears that the larvae have attacked only diseased tissues 1 while in the case here con- sidered no diseased or traumatic condition was observed. At Gaya, Eritrea in September 1942 a single mature larva of Musca vicina was removed from the external meatus of a Suda- nese laborer. The ear was not injured in any way but did con- tain a considerable quantity of wax. The laborer when he re- ported at a dispensary stated that he had been having an ear ache for four days. The larva was removed and the laborer re- turned to work. Some hours later he was questioned regarding the ear ache and stated that it had disappeared shortly after the removal of the larva. It would seem probable that the larva had entered the external meatus when the laborer was either asleep or lying on the ground. Tn the general area fly breeding was abundant at this time. Whether the larva had actually undergone any development in the ear is not known. 1 JAMES, M. T., The Flies That Cause Myiasis in Man, U. S. Dept. Agr. Misc. Pub.

Articles irrele- vant to American entomology will not be noted; but contributions to anatomy, physiology and embryology of insects, however, whether relating to American or exotic species will be recorded. This list gives references of the year 1950 unless otherwise noted. Continued papers, with few exceptions, are recorded only at their first installment. For other records of general literature and for economic literature, see the Bibliog- raphy of Agriculture, Washington, and the Review of Applied Entomology, Series A, London. For records of papers on medical entomology see Review of Applied Entomology, Series B. NOTE: The figures within brackets [ ] refer to the journal in which the paper ap- peared, as numbered in the List of periodicals and serials published in our January and June issues. The number of the volume, and in some cases, the part, heft, &c. is followed by a colon (:). References to papers containing new forms or names not so stated in titles are followed by (*); if containing keys are followed by (k) ; papers pertaining ex- clusively to Neotropical species, and not so indicated in the title, have the symbol (S).

BROWN, JR., Biological Laboratories, Harvard University In his recent book, "Ants of North America," Dr. W. S. Creighton has made a very important advance in the taxonomy of the familiar carpenter ants belonging to the Caniponotits (s. str.) hercnlcanus group. Among the chief points of interest in this treatment is the recognition of the synonymy of herculean us var. m'h\inf>eri with the "typical" hercnlcanus. This synonymy will no doubt be applauded by sensible myrmecologists, for no one has ever been able to show any morphological differences between the Eurasian and North American populations. Dr. Creighton has also raised the common eastern pennsylvani- cus to separate specific status, and I think his evidence for this move is strong enough to deserve the support of all workers. Furthermore, a number of variants that have managed to persist in the literature are exposed as synonyms, mostly based on in- sufficient or poorly preserved material. In this one publication, Dr. Creighton has presented ant taxonomy, in Caniponotits and other groups, with the most prodigious act of unscrambling that has yet been performed on this or any other continent. His work will undoubtedly form the bedrock systematics for all future work on Nearctic ants, and changes to be made during the "morphological" period of our labors will be largely in the nature of retouches of this single contribution. To the present author, two of the most important, yet still relatively minor, corrections that should be made lie with the forms Creighton has called Caniponotits pennsylvanicus modoc (157) 3 - 158 ENTOMOLOGICAL NEWS [ Nov., '50 Wheeler and C. pennsylvanicus ferrugineus (Fabricius). I am convinced that neither form can be placed as a subspecies of pennsylvanicus. Camponotus herculeanus modoc Wheeler In my opinion, modoc is much more logically treated as a south- ern race of herculeanus than as a western race of pennsylvanicus. Modoc ranges widely in the mountains of the western United States and in subboreal regions of the Pacific Northwest, and its northern limits roughly meet the southern low altitude limits of herculeanus herculeanus in a broad belt near the Canadian Border. Specimens stemming from this broad region seem to intergrade between the two subspecies, although the material I have seen could certainly stand supplementation through further collections. Modoc can be distinguished from the northern and alpine form in that the reddish color of the propodeum and petiole has been replaced by black, so that modoc is concolorous black except for the legs. Also, the gastric pubescence of modoc tends to be a little longer, often surpassing the posterior borders of the gastric segments in the middle. These relatively pubes- cent specimens were thought by Wheeler to represent inter- grades between modoc and pennsylvanicus, and it is possible that Dr. Creighton is following this line of thought. A reexamination of modoc, pennsylvanicus, and /?. herculeanus specimens, com- mon in most collections in this country, should convince most workers that the interpretation given here has the better chance of being correct. Camponotus ferrugineus (Fabricius) This form is completely blanketed distributionally by the range of pennsylvanicus. Morphologically, it differs from pennsylvanicus (so far as anyone has been able to tell) only in color. This color difference, however, is quite striking, and there are no recorded instances of difficulty in distinguishing ferrni/incits in the field. Dr. Creighton's treatment of this ant is extraordinary in that he has allowed it to remain as a sub- species of pennsylvanicns in spite of the complete and exceed- Ixi, '50] ENTOMOLOGICAL NEWS 159 ingly detailed sympatry shown by the two forms. His aberrant procedure has, I believe, been forced by the conflict of his belief in sympatry and lack of intergrades as reliable specific criteria on the one hand, and his profound distrust of color as the same sort of criterion on the other. By his own taxonomic principles, Dr. Creighton will even- tually have to resolve this dilemma for himself. Meanwhile, I feel confident in proposing that ferrugineus be raised to separate specific rank. The prospect of considering the striking color difference as the sole morphological point of differentiation so far discovered does not disturb me in the least, even though I realize that other species of the same group (in Europe and Asia) are extremely variable in coloration. The major taxo- nomic fact supporting this view, and one recognized by Dr. Creighton, is the lack of known intergradient color forms con- necting the two species. This fact has been noted by several authors, and it appears to hold true even in areas where nests of the two forms may be only a few feet apart. The flight time of the sexual phases frequently coincides to the day, at least in Pennsylvania and eastern Massachusetts, so that ample oppor- tunity is probably presented for interbreeding. To allow, therefore, for the possibility of the cospecificity of the two forms, one would have to postulate that the genetic factor or factors controlling color would operate on an "all-or- none" basis in this case. Furthermore, the random association of queens of mixed origins should certainly result in mixed pleometrotic nests if such an "all-or-none" theory is to be accepted. Xo mixed nests are known in nature. There is a biological difference that will aid in separating the two as species. In areas where they occur together, pcnnsyl- vamciis is usually the more common species. While it will ac- cept a rather wide range of nest sites, pennsylvanicus (in the area of sympatry ) as found in relatively undisturbed forest areas nearly always nests in standing timber. This standing timber may be partially rotten or largely sound. Dr. Creighton's belief that the tunnels of this ant are driven only into decaying parts of the sound timbers or standing trees is certainly incorrect, as 160 ENTOMOLOGICAL NEWS [Nov., '50 has been shown abundantly in the literature both for pennsyl- vanicus (cf. Townsend, 1945, for bibliography) and for hercn- leanus herculeanus (cf. Eidmann, 1928). Dr. R. B. Friend, Connecticut State Entomologist and one who has extensively investigated ant damage to telephone poles in his state, assures me that pennsylvanicus can and will tunnel extensively in sound poles there. I myself have watched for long periods at a living sycamore tree housing a colony of pennsylvanicus at Philadel- phia. The sawdust brought out and dropped to the base of the tree by the ants was large in amount, and in periods of great tunnelling activity was creamy white in color, the shade of new sawdust fresh from the saw. It seems probable that the original entrance to the interior of the tree is often or always forced through a decayed or otherwise damaged place, however, and it is true that pennsylvanicus will also nest in wholly or partially decayed wood. Nests of pennsylvanicus (in the sympatric zone) are rarely made in "red-rotten" logs or stumps, and the soil itself is rarely penetrated by the galleries. In these respects, ferrugineus differs sharply, for its nests are almost invariably in or beneath rotten logs at the punky "red" stage. The galleries, in all of the many nests I have seen, pene- trate the soil beneath the log or stump to considerable depths. Often the major population of the nest will be found in the sub- terranean chambers, and if the log be removed, the colony will often stay on living underground at the same spot. Anyone who cares to survey the biological statements concerning ferrugineus in the various state lists and similar sources will find that this ant behaves in an essentially similar fashion throughout its range. Perhaps the coloration is an adaptation to nesting in this reddish environment, and the same is possibly true of C. nove- boracensis (Fitch), a more boreal species also commonly found in red-rotten logs and stumps. The combined color differences and ethological peculiarities, and also the distributional considerations, leave little alternative to considering ferrugineus as a good and separate species.

VAN PELT/ University of Florida, Conservation Reserve, Welaka, Florida Within the past few years, two instances of parasitism were found within the nests of Pheidole dentata Mayr. In one case the parasites were determined hy Mr. A. B. Gahan of the United States National Museum as the chalcid Orasema robertsoni Ga- han, and in the other case Mr. Gahan determined the parasites as Orasema sp., possibly robertsoni Gahan. In the latter case insufficient material was available for specific determination. The first parasitized colony was collected in the Welaka Re- serve of northeastern peninsular Florida on September 19, 1949. This nest was in a hardwood stump in mesic hammock (Mag- nolia grand i flora — Ile.v opaca association ) . The number of ants within the nest was 174, including \2 soldiers. Qnparasitized pupae and larvae were present, along with an almost equal num- ber of parasitized immatures. Many different sizes of Orasema larvae were found, ranging from small insignificant points on the ant pupae or larvae, through a characteristic striped stage, to the late stage larvae with vesiculate knobs on its lateral borders. All were attached to the anterior portion of a Pheidole larva or pupa (fig. 1, A). 1 Contribution of the Department of Biology, University of Florida. Gainesville. 162 ENTOMOLOGICAL NEWS [Nov., '50 Different size Orasema pupae were also discovered (fig. 1, B). These pupae, when they first drop from the ant host, are enclosed in a vesiculate skin, and only later do they become fully formed. There were four fully formed pupae counted within the present nest, and three of these were pigmented. Similar stages of 0. z'iridis are well illustrated by Wheeler (1910: 415). FIG. 1. A, Phcldolc larva with an Orasema larva attached anteriorly: B, fully formed and pigmented Orasema pupa ; C, phthisergate of Pheidole worker. The other case of parasitism was observed in a nest of Pheidole dentata Mayr taken about six miles north of Gainesville, Florida. The colony, collected on October 12, 1946 from a long- leaf pine (Pin us palnstris) log in the late stages of decay, oc- curred in a longleaf pine flat woods (Finns palnstris-Aristida stricta association). It is noteworthy that both parasitized nests were taken in the fall. Many deformed phthisergates, or worker pupae which have, through Orasema parasitism, lost the necessary body fluids to Ixi, '50 J ENTOMOLOGICAL XE\VS 163 develop correctly, were present in both nests (fig. 1, C). No phthisogynes, or similarly affected female pupae, were observed, but several parasitized female larvae were found. According to Wheeler (1910: 418) the ant larvae parasitized by Orasema are in many cases able to pupate, but the affected pupae are unable to emerge. The writer wishes to express his appreciation to Mr. A. B. Gahan for his determinations of Orascina and to Miss Esther Google for the drawings which appear in this paper.

S. Fisheries Tract, at light-trap No. 3, July 1-2, 1946 (R. E. Bellamy) ; Collector's No. 1525; returned to Bellamy. Paratopotypes: 3 Jcf, with the type ; 1 J1, July 26, 1946; Bellamy No. 1605. Paralyse: g, Neel Gap, Union County, Georgia, July 5, 1947 (P. W. Fattig). I am most pleased to name this very distinct fly for the col- lector, Dr. R. Edward Bellamy, who has done important work on the crane-flies of Florida. The species is entirely distinct from the only other eastern species, the genotype Atarba (Atarba) picticornis Osten Sacken, and also from the species in Cuba and the southwestern states. The most evident distinctions are found in the coloration of the antennae and abdomen, and in the structure of the male hypopygium, particularly the outer dis- tistyle and aedeagus. The occurrence of the species in the mountains of northern Georgia was quite unexpected and indi- cates a much wider range for the fly than is known at this date. Erioptera (Mesocyphona) femora-atra n. sp. Allied to caloptera; size relatively small (wing, female, under 4 mm.) ; mesonotal praescutum huffy, with two broad black longitudinal stripes ; femora black, the bases and a narrow ring at near three-fifths the length yellow, remainder of legs yellow ; wings brown, spotted and dotted with white, the dark color much exceeding the pale in extent. J\ Length about 3.4—3.5 mm. ; wing 3.6-3.7 mm. Rostrum and palpi black. Antennae with scape and pedicel black, more or less variegated with paler ; basal segments of flagellum pale yellow, the outer ones passing into brown. Head huffy, the center of vertex dark brown. Pronotum brownish black medially, the scutal lobes pale. Mesonotal praescutum buffy with two broad black intermediate stripes that are much broader than the median interspace, the latter slightly wider behind ; lateral praescutal borders nar- rowly dark brown, crossing the suture behind onto the scutal lobes ; intermediate praescutal stripes continued caudad, in- cluding the mesal portions of the scutal lobes ; scutellum buffy ; Ixi, '50 | ENTOMOLOGICAL NEWS 171 postnotum darkened. Pleura dark brown, with a broad longi- tudinal silvery stripe. Halteres with stem whitened, knob dark brown. Legs with the coxae and trochanters obscure yellow ; femora brownish black to black, with a narrow yellow ring at near three-fifths the length, the bases restrictedly obscure yel- low ; remainder of legs light yellow. Wings with the ground color brown, more saturated along the costal border, variegated by numerous white spots and dots, including a series of about seven along the anterior border, the second not reaching costa; fourth pale area continued across wing as a narrow, only slightly broken band that extends to vein On; all longitudinal veins be- hind and excepting R- with a white marginal spot ; remaining cells of wings with scattered white spots ; in brief, the pattern is dark with a much more restricted pale pattern ; veins pale brown, pale in the white areas. Venation : Cell Mz open by the atrophy of the basal section of M?>. Abdomen chiefly dark brown. Habitat. — GEORGIA. Holotype: $, Valdosta, Lowndes County, May 28, 1946 (P. W. Fattig). Paratopotypes: 2$$. Although the present fly is generally similar to Erioptera (Mesocy phono) caloptera Say, it seems certainly to be distinct in the pattern of the legs and wings, as described. All three type specimens are virtually identical in the points indicated. Notes on Some Aquatic Insects of the Brandywine Creek Drainage, Chester County, Pennsylvania By JOHN W. H. REHN, Research Associate, Academy of Natural Sciences of Philadelphia During 1948 a biological survey of the Conestoga Basin, Lan- caster County, Pennsylvania, was carried on by the Academy of Natural Sciences of Philadelphia for the Sanitary Water Board of the Commonwealth of Pennsylvania. At this time a limited number of similar collections was made in the Brandywine Creek Drainage. As a result of the interest shown in stream pollution in the state, particularly in the Brandywine Drainage, it lias 172 ENTOMOLOGICAL NEWS [Nov., '50 been thought advisable to present the small amount of informa- tion assembled during that season's work. In addition it is believed that some of the distributional records may be of interest to those working on the various groups of aquatic insects. A basic report has recently been published on the survey of the Conestoga Basin,1 but due to the limited character of that undertaken in the Brandywine Drainage none has been pre- sented. The method of survey on this drainage was essentially the same as that utilized on the major survey, with the same technics, methods of sampling and recording. It is desired to thank all of those that participated in the survey for their help in the accumulation of the material here presented. All of the material listed represents immature individuals ex- cept in the Hemiptera and Coleoptera where the material is adult unless otherwise noted. Incomplete identifications are listed only as a help in establishing the various ecological associations present. A listing of the various localities examined and the conditions encountered is given below. The densities at the stations are listed, as in the other stream survey report: (1) rare, (2) few, (3) frequent, (4) common, (5) very abundant. Station A. Brandywine Creek, 2y2 miles north of Coatesville. Average width 5 feet. Average depth 15 inches. Shores wooded lowland. Bed of stream some boulders, mainly gravel or sand and a little mud. This station was first examined 23 July 1948 (Al) and a second time 13 August 1948 (A2). This is station 129 of the State Stream Survey. Superficially this appeared to be a healthy station. Station B. Brandywine Creek south of bridge at Coatesville. Average depth 19 inches. Shores weeds and industrial wastes. Bed of stream mainly rubble, some clay. This station was first examined 21 July 1948 (Bl) and a second time 11 August 1948 (B2). This is station 126 of the State Stream Survey. 1 PATRICK, RUTH, A proposed biological measure of stream conditions, based on a survey of the Conestoga Basin, Lancaster County, Pennsylvania. Proceedings Academy of Natural Sciences of Philadelphia, CI, pp. 277- 341, map, (1949). Ixi, '50 | ENTOMOLOGICAL NEWS 173 This station was heavily contaminated with oil and at the time of the first examination no insects could be found. Statio)i C. Brandywine Creek at Modena. Average width 50 feet. Average depth 12 inches. Shores low vegetation. Bed of stream mainly gravel, with mud near the shores. This station was first examined 21 July 1948 (Cl) and a second time 13 August 1948 (C2). This is station 127 of the State Stream Survey. This station was heavily contaminated with oil, hut not as much so as B. In addition garbage and other wastes were also present. Station D. Brandywine Creek at Embreeville State Hospital. Average depth 20 inches. Shores pasture, with cut banks. Bed of stream about one-half rubble and sand, remainder rock with a fine mud covering. This station was first examined 21 July 1948 (Dl) and a second time 16 August 1948 (D2). This is station 128 of the State Stream Survey. Superficially this appeared to be a healthy station. Station E. Brandywine Creek above Lenape. Average depth 13 inches. Shores mixed second growth. Bed of stream mainly rocks and rubble, a little mud near the banks. This station was examined 13 August 1948 and is station 141 of the State Stream Survey. This appeared to be a healthy station. Station F. Brandywine Creek near Lenape. Average depth 19 inches. Shores mixed vegetation, banks cut. Bed of stream rubble to rocks except for mud near the shores. This station was examined 13 August 1948 and is station 142 of the State Stream Survey. At this station there was some traces of oil contamination. ODOXATA Agrionidae Agrion sp. A2 3. D2 2. Hctacrina sp.

The diversity of forms at the various stations appears to be of some interest. It should be noted that Chironomids are treated as a single entity. At station A, 58 different forms were found, 40 on the first and 41 on the second examinations. At station B, only two forms were found, both on the second ex- amination, there being no insect life present at the time of the first examination. At station C, seven different forms were found, seven at the time of the first examination and only three at the second sampling. At station D, 18 different forms were found, with 13 types present at each sampling. At station E, 10 forms were found and at station F, 17. When one examines the information for the various major groups as distributed from the headwaters, through pollution and downstream, the following conclusions can be made. The Odonata were well represented at A, practically absent from B, and then show a gradual increase in diversity and numbers down- stream. The Ephemeroptera showed a good mixed fauna at A, and were absent from B. Downstream the families other than the Ephemeridae reappeared but in reduced variety and number. In the Plecoptera only the Perlidae were found at A, and mem- bers of this family were again encountered at F. Of the Xeu- roptera, Corydalns was the only common form and this soon re- turned following the heavy pollution. Of the Trichoptera five families, represented by six species, were found only at A, while the Hydropsychidae, which were moderately well developed at A, reappeared at station F. Neither the Hemiptera nor Coleop- tera were sufficiently collected to warrant the drawing of any conclusions. Of the Diptera either insufficient material, as in most families, or incomplete determinations do not allow the forming of conclusions. It is interesting to note that the single aquatic lepidopteron, Elophila, was present in both stations A and D. 178 ENTOMOLOGICAL NEWS [Nov., '50 Taxonomic Notes on Two South American Psyllids (Homoptera) By LEONARD D. TUTHILL, Department of Zoology and Entomology, University of Hawaii As a result of study of several species of South American Psyllidae, mostly received from Senor Carlos A. Lizer y Trelles of Argentina, I am able to dissolve to some extent the confusion which has surrounded the nomenclatorial and taxonomic status of two of the species. Genus Gyropsylla Brethes 1921 Gyropsylla Brethes, Revista de la Facultad Agronomia Universidad National de la Plata, Argentina 14: 87. 1925 Metaphalara Crawford, Broteria Ser. Zool. 22 : 60. Several specimens from the Territory of Missiones, Argentina determined as Metaphalara spegazziniana by Lizer, furnish con- firmation of the close relationship of this species with Psylla lllcis Ashmead of North America as indicated by Lizer and Crawford. The latter erred however in erecting the genus Metaphalara for these two species and the related canncla. Gyropsylla is the valid name of the genus. The synonymy of the type species, Gyropsylla spegazziniana (Lizer), is as follows: \9\9Paurocephalaspegazziniana Lizer, Marcellia. 16: 103. 1921 Gyropsylla Ulclcola Brethes, Revista de la Facultad Agronomia Universidad National de la Plata, Argentina, 14:88. 1925 Metaphalara spegazziniana Crawford, Broteria Ser. Zool., 22:72. Genus Holotrioza Brethes 1920 Holotrioza Brethes, Aspiraciones, 2 : 132. The psyllid described by Scott in 1882 (Trans. Ent. Soc. Lon- don, 1882: 443) as Psylla dnvauae was properly assigned to a genus other than I'syllu by Brethes. In 1920 he erected a new genus, Holotrioza, for this species. This was done in a discus- Ixi, '50] ENTOMOLOGICAL NEWS 179 sion of galls formed on the host plant, Schinns polygannis (Cav.) Cabr. His choice of a name was unfortunate however, as the insect belongs to the subfamily Pauropsyllinae rather than to the Triozinae. As the genera of this subfamily are at present quite incompletely known and mostly poorly defined the exact relationship of this form within the subfamily is doubtful but it appears to be most closely related to Pauropsylla. Several specimens collected at Buenos Aires by Lizer have been examined. Current Entomological Literature COMPILED BY R. G. SCHMIEDER. Under the above head it is intended to note papers received at the Academy of Natural Sciences of Philadelphia and the University of Pennsylvania, pertaining to the Entomology of the Americas (North and South), including Arachnida and Myriopoda. Articles irrele- vant to American entomology will not be noted; but contributions to anatomy, physiology and embryology of insects, however, whether relating to American or exotic species will be recorded. This list gives references of the year 1950 unless otherwise noted. Continued papers, with few exceptions, are recorded only at their first installment. For other records of general literature and for economic literature, see the Bibliog- raphy of Agriculture, Washington, and the Review of Applied Entomology, Series A, London. For records of papers on medical entomology see Review of Applied Entomology, Series B.

The entomologist who is dealing with fundamental problems is first of all a biologist. He is investigating a special group that is so rich in species as to outnumber all other groups of organisms, with the possible exception of the Protozoa and Bacteria. The entomologist is indeed fortunate to have such a rich variety of working material, for he can not only test estab- lished biological principles, but can also formulate new relation- ships on the basis of his own work. Since much biological work is dependent on chemistry-physics and mathematics (scnsii lato, i.e., both quantitative and qualita- tive), many biologists will be interested in the young science of mathematical biophysics. Unfortunately this science is only in Ixi, '50] ENTOMOLOGICAL NEWS 189 its infancy at present. It will probably be many years before it has developed to a very satisfactory state. The chief reason why a theoretical biology is expected to grow slowly is the large and heterogeneous mass of largely undigested data that have been accumulated. Portions of these data have been worked out, in many cases quite satisfactorily from the standpoint of theory. However, there is no satisfactory general theory of biology as there is in the case of physics. The section of biology that ha- the most satisfactory unifying theory is genetics, and it is in- teresting to note that this science was founded on a partially axiomatic (scnsu Woodger et al.) basis. The biologist can hardly hope to attain easily a position comparable to that of the present-day physicist because of the vastly more complex situa- tion with which he has to deal. The situation that has been attained in theoretical and experimental physio may be envied by scientists whose houses are not in such fine order, but it must be remembered that it took a number of brilliant mind> over a hundred years to arrive at this point. And also the data of physics during this period of development were less numerous and less complex than the mountain of facts and alleged fact- which the present-day biologist must begin to organize. Two main attempts have been made to place biology on a general theoretical basis. The first, the work of J. H. Woodger, is probably more powerful than the present work of Rashevsky. Woodger's book, The Axiomatic Method in Biology. Cambridge University Press, 1937, has, however, elicited little or no re- sponse. It contains a new and strange tool, and it is, perhaps, because of the natural disinclination of most of us to take the time to master a new and complex method that the book has been so little read. The present work of Uashcvsky utilizes a largely quantitative approach to biology. It is hoped that this initial and circumscribed attempt to rationalize biology will ultnnatrlv de- velop to the point of furnishing a fairly satisfactory unifving theory. Such a development is presumably years away because of the complexity and magnitude of the task. Professor Rashev- sky and his students are to be congratulated on making a start in this worthwhile endeavor. 190 ENTOMOLOGICAL NEWS [Nov., '50 To attain the desired goal, vh., a theoretical biology, deduc- tions from which will indicate new and fruitful lines of investiga- tion, a symbolic language must be used. Furthermore any sym- bolism in order to be useful, must present more than a mere translation from verbal description to symbolic description, some of which is evident in the present work. Symbolic statements of relationships from which significant consequences can be de- duced, and later tested by experimentation or observation have the advantage of being relatively free from the semantic difficul- ties inherent in natural quasi-logical languages. The long history of human thought has adequately demonstrated this point. The chief basis for Rashevsky's theoretical biology seems to rest on the kinetic theory and not on thermodynamics, which the author has called "thermostatics." He expressed the opinion that at present, at least, he does not intend to use thermody- namics in his work because he considers this tool to be inade- quate for open systems. Be that as it may, I seem to recall that J. Willard Gibbs (ca. 1876) wrote a famous paper on the equi- librium of heterogeneous systems. Certainly a phase of a hetero- geneous system may be considered as open rather than closed. A recent writer has claimed much to be new, true and interesting about open systems in biology. It is to be hoped that some mathematician will write a critique of his paper, showing how neatly certain unwanted constants and variables were made to do a disappearing act ! The book under consideration contains 54 chapters, which are distributed among four major sections. The titles of the sections are: I. Mathematical Biophysics of Vegetative cells; II. Mathe- matical Biophysics of Excitation and Conduction in Peripheral Nerves; III. Mathematical Biophysics of the Central Nervous System ; IV. The Organism as a Whole and the Organic World as a Whole. Those familiar with the earlier works of the Rashevsky school will immediately see upon examining the present revised edition that it is a composite of the first edition (1938), Advances and Applications of Mathematical Biology (1940), and various journal articles, many of which are taken from The Bulletin of Mathematical Biophysics. This journal. Ixi, '50 | KXTOMOLOGICAr, XF.US a quarterly founded in 1(>31'. is under the editorship of N. Rashev- sky. No douht a mathematician \vho picks up this book will think- that it has too much obvious detail, and that it is, perhaps, not too rigorous in spots. Many biologists will in all probability maintain that the contrary is true. Any author has a problem in attempting to satisfy readers of various tastes and backgrounds. Professor Rashevsky has apparently attempted a compromise, intended to partially satisfy a variety of readers. It would seem that a biologist whose training has included the calculus and dif- ferential equations should not experience too much difficulty in reading this book. In this connection it is unfortunate that in one's mathematical schooling in this country it takes so long to wade through so many totally unedifying topics only to stop just short of the really valuable calculus. This is particularly lamentable in that a reasonably good knowledge of at least the main ideas of the calculus could easily be the end product of a non-engineering curriculum. My own meager knowledge of mathematics was acquired largely outside of school, and then put to good use during two of the war years when I taught in the Mathematics Department (State College, Raleigh, Xorth Carolina. Such a method of outside study in mathematics has certain points in its favor, for one can go as slowly or as rapidly as one's natural laziness and wits dictate! And slow or fast, the game of mathematics is far more entertaining than bridge and good relaxation from real chess. In summary, 1 wish to point out that Professor Rashevsky i> keenly aware of a number of the limitations of his book. In fact, he goes into a very detailed analysis of a number of them in the preface. The reader will want to examine this part of the book, not only because of Professor Rashevsky's critique of his own work, but because of certain interesting historical details. This book is recommended to any biologist who is looking for a book about biology that is different. — MKRLK \Y. \Yixo.

XYSTODESMIDAE Brachoria benderi, n. sp. figs. 1 and 2 Nearest Brachoria separanda Chamherlin 1947 in size, hut differing from that and other species of the genus in the details of the male gonopods and in the color. Male Iwlotypc. — Metatergites brown-black ; a thin bright pink line on lateral margins of collum and keels and on the caudal segment : a small pink dot on each pore-bearing keel anterior to and slightly medial to the pore ; protergites cream, partially ex- posed in middle and posterior body regions, giving the body a moniliform appearance ; legs, venter, pleurites light cream color ; distal two segments of antennae brown, remainder tan. Coxae and prefemorae spinecl. Sternum between each two pairs of legs of a segment slightly depressed, the caudal margin sharply raised and convex ; no indication of sternal spines or processes. Beginning with the fourth segment, the caudal mar- gins of the keels are produced caudad, becoming acute posteri- orly. The lateral margins of the keels are raised, with the pores on the dorsal surface of the margins. /;; silu the distal one-third of the main blades of the gonopods are superimposed, the two forming with their bases a rough (193) 194 ENTOMOLOGICAL NEWS [Dec., '50 circle ; the ends of the accessory pieces are almost in contact in the medial line. The base is thickly setose, and the main blade is sparsely so as far as the transverse ridge. Beyond the ridge the blade is flattened, attenuated, and turns sharply dorsad. Views of the left gonopod are shown in figs. 1 and 2. Length 30 mm., width 7 mm. B-C-H of segment 14 .21- 1-.57. Locality. — Mississippi, Rankin County, Piney Woods. One specimen was collected by Mr. Singleton Bender April 22, 1950. Nannaria davidcauseyi n. sp. figs. 3 and 4 The male gonopods of this species are of the castanea (Mc- Neill 1887) type; they are distinct in the configuration of the thin keel at the distal end of the main blade. Male holotype. — Color unknown. Body with shape typical of the genus. Sternites of the second pair of legs of each segment from the sixth through the eighteenth produced adjacent to the legs into a blunt spine as typical of the genus ; a few setae on the sternites. In situ the gonopods cross medially about one-third of their length from the distal end, with the medial process and the spur at its base visible. Details of the left gonopod are shown in figs. 3 and 4. Length 21.8 mm., width 4 mm. Locality.— Arkansas, Newton County, about three miles northwest of Jasper. Two recently molted males and two larvae of the last larval stadium were collected by Dr. David Causey Aug. 25, 1950, from an oak-hickory woodland on an east hillside. In the male paratype the spur at the base of the medial spine of the gonopod was much less distinct than that of the type speci- men, and the keel at the end of the main blade showed a slight variation in shape.

Left lateral view of male holotype showing modification <>f pleurite and telopodites Siphlonurinae. Some of the difficulties of this couplet may be obviated by using the form of the distal margin of the labrnm as a key character. All Baetinae seem to be characterized by a distinct notch in this margin while the same margin in the Siphlonurinae is straight, rounded, or shallowly emarginate. Adult males of Baetodcs will run to l^scitdoclocon in Traver's key to the North American genera of the Baetinae (op. ci/.: 655), but apparently can be separated by adding the following couplet : l\i, '50 | KXTOMOLOGK AI.

I'actodcs The adult of />. spinijcntin is also characterized bv having mid- dorsal abdominal spines on tergites 2-5, a feature of the nymphal genotype. It is probable that both the new records presented above are representatives of undescribed species the naming of which should await the discovery of adult specimens. Further Records of the Occurrence of the European Praying Mantis (Mantis religiosa L.) in Southern Ontario. (Orthoptera) By W. \Y. Ji'DD, Department of Zoology, University of Western Ontario, London, Ontario. In an earlier paper (1947) the writer recorded the occur- rence of the Praying Mantis in the vicinity of Hamilton, On- tario, during the summer of 1946, and Smith (1949) discussed the distribution of this insect in southern Ontario, basing his account on records of collections up to the year 1948. Since the publication of these two papers the writer has had an op- portunity of examining specimens, in collections at McMaster University, Hamilton, Ontario, which show that the mantis was present at Hamilton as early as 1941 and which represent collections at other localities in southern Ontario. These col- lections are as follows: Green female, Ancaster, Sept. 1, 1948; brown female, Brantford, Sept. 6, 1947; green male, Burling- ton, Sept. 12, 1947; brown female. Cayuga, Aug. 18, 1948; green male, Dundas, Sept., 1943; green female, Hamilton, June, 1942; brown male, Hamilton, Sept., 1945; green female, Hamil- ton, July, 1941 ; brown male, Hamilton, Oct., 1941 ; brown male. St. George, Aug. 26, 1(>4S; brown male. South Cayuga, Aug. 31, 1948; green male, Toronto, Sept. 3, 1947; green male, Troy. Aug. 2(>, 1948; brown female. Turkey Point. Sept., UM3 ; brown female, West Flamboro, Oct. 16. 1949. During the years 1941-lt>4(> a total of 82 adult mantids wa> 206 ENTOMOLOGICAL NEWS [Dec., '50 collected in the vicinity of Hamilton and at other localities, the collections in 1946 being reported by Judd (1947). The distri- bution of these 82 specimens, with regard to color and sex, is presented in the following table : Green Brown Male Female Male Female 1941 1 1 1942 1 1943 1 1 1945 1 1946 13 5 2 1947 3 8 3 2 1948 12 10 3 6 1949 4 3 2 Totals 29 29 11 13 58 24 These figures indicate that the number of green individuals is approximately twice the number of brown, and that the color is independent of sex. As recorded by Judd (1947) adults were placed in battery jars with twigs on which to lay their egg masses. A sudden movement outside the jar would occasionally cause a mantis to assume a "scaring attitude." On Oct. 6, 1947, a green female, on being startled, instantly turned to face the source of the dis- turbance. The wings were held vertically and fully outspread above the back and the tip of the abdomen was bent upward and forward between the wings. The insect reared upward with its fore-legs rampant, and the coxae were held close to- gether and turned so that their inner surfaces faced forward, and the two white spots outlined in black, on the coxae, looked like a pair of large, close-set eyes. The mantids were also ca- Ixi, '50] ENTOMOLOGICAL NEWS 207 pable of stridulating. On Sept. 10, 1947, a brown female as- sumed the "scaring attitude" with the wings outspread and held vertically above the back. The abdomen was flipped rapidly backward and forward, its sides rubbing on the veins of the dorsal surface of the hind wings, causing a rasping sound. LITERATURE CITED JUDD, W. \Y. 1947.

Occurrence of Perilitus coc- cinellae (Schrank), a Parasite of Adult Coccinellidae, in North China (Hymenoptera, Braconidae) By C. L. Liu. Tsing Hua University Since reporting the occurrence in Yunnan of the Euphorine Braconid, Perilitus coccinellae (Schrank), a parasite of adult Coc- cinellid hosts, in this journal,1 search has been continued for this remarkable species after our return to the north. Five speci- mens have so far been encountered during the months of April through June. Two of these were collected from the vicinity of Tsing Hua Yuan where the University is located, and the re- maining three from the District of Furring, in eastern Hopei Province. For Tsing Hua Yuan the latitude is 40°00' N and for Funing, 39°53'30" N, with a difference of 6l/2 minutes. Tsing Hua Yuan is situated on longitude 116° 17' E, and Funing. 119°12' E, the latter being approximately 250 kilometers (air distance) due east from Tsing Hua Yuan. The elevation for 1 Liu, C.

News, 55 : 235-7. 208 ENTOMOLOGICAL XE\VS | Dec., '50 Tsing Una Yuan is exactly 50 meters and that for Kuning is approximately 30 meters, the latter being not far from the coasl i if the Gulf of Liaoning. Geographical relationship places these two localities in the same category and their climate is similarly north temperate. These preliminary findings extend the geographical distribu- tion of Pcrilitus cocciucllac by nearly 15 degrees to the north ol Yunnan on mainland China. As the recorded hosts of this parasite are well represented in the intervening areas between Hopei and Yunnan, there seems every probability that the present parasite will sooner or later be discovered in this region. Simi- larly one ma)' confidently expect its occurrence in the North- eastern Provinces. Sonan ( 1030)- reported collecting Perilitns cocciucllac from Taipei (Taihoku), Formosa. This locality has a latitude of 25 2' N and longitude of 121°30'30" E and an elevation of below 50 meters. As compared with Kunming. Tsing Hua Yuan is 15° north and very much lower in elevation. Taipei is almost on the same latitude as Kunming but with an elevation equaling that of Tsing Hua Yuan. The climate in Taipei is considerably warmer than in Kunming but since it is still some 2° above the Tropic of Cancer, it is still within the temperate zone. It may now be said that so far as China is concerned the prob- able distribution of Pcrilitus cocciucllac lies within an area roughly bounded on the north by 40° and south by 25° latitude and on the east by 121° and on the west by 102° longitude. The climate of this area is temperate. The five cases reported herein involve three different host species : Coccinclla a.viridis Pallas, Coccinella sef>tcinf>nnctata L. and Adonia raricyata Goeze. As may be noted, all these are aphid feeders. Although the host list for North China may be extended with further investigation, it must be mentioned that of the hundreds of specimens of the two local species of Epi- lacJina, no case of parasitism by 1'crilitns was ever observed. Sonan (1939)- reported the same thing from Formosa. 2 SONAN, JINHAKU. 1939. On the lady-birds parasite, I'crilihis coc- cinellac (Schrank) ( Hym. Braconidae). (In Japanese.) Trans. Nat. Hist. Soc.
