Sphex (Ammophila) nigricans. Dahl. Several nests were seen on October 12, 1930, at Pittsburgh Lake, 111 . (Opposite St. Louis, Mo.). The mothers were excavating nests although it was very late in the season. The burrows in the ground were “L” shaped ; the neck, one-half inch in diameter by one-half inch long; the pocket at the bottom, one-inch wide by three-fourths inches deep. I found one caterpillar at the bottom of each of the three nests I opened. The egg was attached to the caterpillar dorso-laterally on the fifth segment in two cases while in the third it was attached to the sixth segment. The caterpillars, only lightly paralyzed, were so very lively that I was worried about the safety of the attached eggs. Two of the caterpillars were encrusted with earth; this indicated that they were subterranean and that the wasp mothers did some underground exploration in hunting them. Sphex (Ammophila) procerus Dahl. This beautiful wasp, found occasionally about St. Louis, was also taken at Old Mines, Mo., feeding on flowers of the white snakeroot. On another occasion a specimen was seen at the Missouri Botanical Garden delving deeply into the flowers of the sedum, Sedum spectabile. This f lower was also chosen by a large number of honey bees ; both bees and wasps almost totally neglected enormous patches of other plants blooming nearby. Sphex (Ammophila) pictipennis. This species is plentiful about St. Louis and an account of its habits appears in “Wasp Studies Afield.” I merely want to record here the existence of a dipterous mimic. Dozens of two-winged flies that resemble this wasp were seen at Allenton, Mo., on August 17, 1930, on the banks of the Meramec River. This fly was identified by Dr. C. T. Greene as Systropus macer Loew. I took the first ones in the net thinking they were Ammophila wasps ; all were seen very close to the nesting site of the wasps. The critics of mimicry often say that mimicry means nothing unless both model and mimic inhabit the same area. Here at Allenton, both model and mimic thrive side by side. Trypoxylon trident alum Pack. A twig taken at Kirkwood, Missouri, June 2, l 9 2 &, gave forth three specimens of this wasp and three parasitic cuckoo wasps ( Chrysis sp.) The parasites emerged one each on June 10, 16 and July 1, 1928; the wasps emerged on June 16, 20 and 28. Pemphredon bipartior Fox. A twig with a nest of this species taken at Kirk- wood, Mo., in December, 1927, gave forth eight adults the following year, between May 30 and June 5. One cell was filled with many individuals of an unidentified plant louse, on which the young fed. Hoplisus (Hoplisoidcs) nebulosus Pack. Several mothers seen digging in the *A11 wasps were kindly identified by Dr. Grace Sandhouse. 2Ô0 THK CANADIAN ENTOMOLOGIST DECEMBER, 1934 white sand at “Sand Cave” near Festus, Mo., on September 6, 1929. Timulla prometha jBlake. Dasymutilla occidentalis Finn. Dasymutilla spar sa Fox. On the sandy bank of the Meramec River, at Allenton, Mo., on August 24, 1930, from three to six females of each of the above three species were taken within an hour. There were several nests of solitary bees and wasps in the same area. Dasymutilla allardi Roh. One female taken at Kimmswick, Mo., September 28, 1930. It fed on honey and lived about nine days in confinement. Bicyrtes quadrifasciata Say. This wasp was seen flying high in the air carry- ing under her body a bug nymph of Anasa tristis DeGeer. She evidently had a nest in the sandy loam on the banks of the Meramec River. The prey was not killed outright and six hours later could still twitch some of its legs. This observation was made August 23, 1930, at Allenton, Missouri. Bicyrtes ventralis Say. Several specimens were seen flying in the hot sun close to the ground on Chestly Island, near Kimmswick, Mo., on July 29, 1930. Tachytes elongatus Cress. A hole in the sand on the shore of Meramec River at Allenton, Mo., had a large mound around it. I found this wasp at the bottom of this twelve-inch burrow. Eucerceris zonatus Say. Dozens of these wasps, all males, were seen at Allen- ton, Mo., August 17, 1930, feeding on flowers of smartweed and also on white snakeroot. Philanthus gibbosus Fab. Dozens of these wasps were seen making hori- zontal nests in a clay bank at St. Albans, Mo., July I2 ? 1931, and about ten mothers were seen digging vertical burrows between the bricks of a back yard wMk in the heart of St. Louis, Mo. Mud nest of Pseudagenia arch ! tecta (xVA). Pseudagenia architecta Say. The nests of this species are usually two celled and made of mud ; the cells fit one into the other and are often found inside the heavy white cocoon of a spider under the bark of trees.* One such two celled nest gave forth adults on August 28, 1930. A three celled nest, taken at Allenton, in January, 1928, gave forth three adults between June 2 and 5, 1928. The three cells were separate and distinct although they were held close together by the surrounding belt of a spider cocoon. A third nest had six cells and was oddly shaped (Fig. 1). This however was not built in a spider web, but was constructed in a mat of dead grass under a box of dirt in my back yard. Five adults (2 males and 3 females) emerged between June 10 and 16, 1932. The fact that some of the adults emerge in early June and others in late August makes one suspect that there are two generations each year. *Wasp Studies Afield pp. 82-83, 1918. IyXVI THE CANADIAN ENTOMOLOGIST 2ÔI Angeniella annecta Banks. A mud nest of seven neat cells was taken at Ran- kin, Mo., from under the bark of a fallen log on July 10, 1931; one cell was completed and ready to be filled; one cell was sealed and had a newly laid egg on a spider; one cell had an egg and two had very young larvae, and the balance of cells contained larvae that had already spun the cocoon. The immature spider that carried the egg was identified as Lycosa sp., by Miss Elizabeth Bryant. The spider had one leg missing and was paralyzed, but still responded to stimulus three days after it was taken from the cell. Angeniella obscura Banks. A mud nest taken in St. Louis County, gave forth four adults of this species between August 1 and 4, 1928. Angeniella bombycina Cress. Several pretty mud cells taken from under bark at Allenton, Mo., gave forth two adults between May 18 and June 5, 1928, and several others emerged July 28 from a nest taken at Antonia, Mo. Angeniella petiolata Cress. One wasp emerged June 10, 1929, from a resealed cell of the pipe organ wasp, Trypoxylon (albitarse) politum. The mother built her own small cell inside of the large one and then sealed the big opening with mud. A CONTRIBUTION TO THE INSECT FAUNA OF TIMAGAMI BY A. W. A.

AND A. SUBARCTICA WLK. BY E. M. WALKER, Department of Biology, University of Toronto. In the writer’s treatise on the North American species of the genus Aeschna (Walker, ’12) the nymph of A. juncea L. was described from exuviae collected by the late Dr. F. Ris at Cierfs, Switzerland. One of the exuviae was accom- panied by a teneral imago. A single female exuvia from Nipigon, Ont., very closely resembling the Swiss specimens, was tentatively referred in the same work (p. 98) to A. subarctica Wlk. rather than juncea , although both species were flying at the spot where the exuvia was found. This was because of slight differences from typical juncea, particularly the slightly longer “lateral appen- dages” (cerci), which would correspond to the longer appendages of the adult female of subarctica. Later events, however, have proved this supposition to be incorrect. The Nipigon exuvia belongs to juncea, as was indicated by the finding of identical exuviae, together with the newly emerged adults at Lowbush, Lake Abitibi, Ont., and Prince Rupert, B. C. Numerous exuviae were also found at Banff, Alta., on Aug. 8, 1921, on the margins of ponds along the railway, where juncea was flying in numbers, and nymphs were found at Prince Rupert •and near the summit of Grouse Mt., Vancouver, B. C. A. subarctica is not known from these localities, not having been reported west of Manitoba. Finally the discovery of A. subarctica with its exuvia at The Pas, Manitoba, in 193 L furnished the proof that the Nipigon specimen could not belong to this species, the true nymph of subarctica being readily distinguishable from that of juncea. The nymph “of Aeschna juncea americana (L) Bart. As pointed out by the writer (op. cit.) American specimens of Aeschna juncea differ somewhat in the adult state from European, and more recently Bar- 268 THE CANADIAN ENTOMOLOGIST DECEMBER, 1934 tenef (’29) has divided the species into several races, the American form being regarded as one of these, the race americana. The exuviae (text fig a) show no constant differences from European juncea , as represented by the Swiss specimens mentioned above with the addition of an exuvia from Ruppersdorf, Czechoslovakia, collected by the writer; but are slightly smaller, a little darker, and less distinctly marked. The two pale, longitudinal, dorsal stripes on the abdomen are laterally well defined on the first four or five segments, but, posterior to these segments, they become increasingly less distinct, tending to break up into pairs of spots, a pair at the anterior mar- gin of each segment as far as the ninth or, in dark indiviudals, not distinguishable Full grown nymphs of (a) Aeschna juncea americana Bart, (b) A. subarctica Wlk. beyond the sixth or even fifth segment. These pale stripes are confluent on segment 1 and scarcely, if at all, divided mesially on segment 2 in most speci- mens, the median dark area being often indistinct anterior to 3. The contrast between pale and dark markings is usually less marked than in typical juncea, but I have a pale specimen from Prince Rupert which is indistinguishable from the typical race in regard to these markings. Usually the median area is no darker than the sides of the abdomen, even the dorsal puncta being but little deepened in colour, if at all. The lateral and dorso-lateral puncta are generally distinct, though inconspicuous, and the sides of the abdomen below the lateral scars are sometimes, but not always, slightly paler than the ground colour of the segments. The head, thorax and legs are, as in race juncea, practically concolorous or with ill-defined paler postocular bands along the sides of the head and pronotum. LXVI THE CANADIAN ENTOMOLOGIST 269 Labium (pi. 11, fig. 2) indistinguishable from that of race juncea (pi. 11, fig. 1) ; width of mentum at base about five-eighths of the width at the distal margin, the sides in the proximal three-fifths feebly diverging and barely convex, distally strongly convex, the greatest divergence before the distal end; median lobe occupying a little more than the middle third of the distal width of the mentum, broadly obtusangulate ; palpal lobes about 1.5 times as broad as the base of the moveable hooks, truncated at apex with the outer angle somewhat rounded off, the inner angle with a minute, sometimes indistinct, tooth. Propleural pro- cesses (pi. 12, fig. 11) about equal in length, the anterior more slender than the posterior. Mesopleural processes* low and rounded (fig. 13). Abdomen as in race juncea , tending to average a little slenderer. Lateral spines (figs. 5, 9) a little longer than in race juncea , (fig. 8) those on segment 6 (fig. 16) not quite so vestigial, those on 8 reaching about three-quarters (in race juncea two-thirds) of the distance towards the base of seg. 9, those on 9 as far back as the middle of 10, or a little short of it. P'araprocts (inf. apps.) a little shorter than 9+10, the proportion being about seven-eighths, more rarely equal ; cerci straight and substyliform, tapering to small, feebly incurved apices, usually about four-sev- enths, or, in the female, sometimes only one-half, the length of the paraprocts; in the male, exceeding the length of the rudiment of the adult inferior appendage by one-third the length of the latter. Apices of gonostyli of female just reaching the hind margin of the ninth abdominal sternum. Total length (mm.) 37-41; hind wing 6.8-7. 8; hind femur 6.2-6-9; width of head 7. 7-8.0; width of abdomen 6.8-7.0. The nymph of Aeschna subarctica Wlk. Since this species was described (Walker, ’12) a closely related form has been found to exist in many parts of Europe. Its discovery in Germany was reported by Ris (’27) who sent me a pair for comparison with A. subarctica , with which species he recognized its close affinity. While differing slightly in colour- pattern, particularly in the much broader lateral thoracic bands, and in the blunter superior appendages of the male, I found no’ more important differences between the European form and the North American subarctica than those which dis- tinguish European and North American specimens of A .* juncea. I therefore confirmed Dr. Ris’s opinion that the European specimens were probably not dis- tinct from A. subarctica. Since the publication of Ris’s paper the same form has been reported as A. subarctica by a number of European writers from many localities in middle Europee. Before Ris’s paper appeared, however, Djakonov (’22) described briefly a new species of Aeschna from northern Russia under the name of A. elizabetae and this form was more fully characterized later by Valle (’29) and Bartenef (29, ’30a). Valle tabulated the differences between A. elizabetae and subarctica and came to the conclusion that these differences were too trivial to warrant specific distinction but that elizabetae was probably deserving of rank as a European race of A. subarctica. I have a pair of elizabetae from Finland, kindly sent to me by Mr. Valle and also a male of the form from central Europe, taken in the Black Forest and sent to me by the late Dr. Ris. These *These are the slightly projecting lower margins of the mesepisterna and mesepimera, serially homologous with the ipiropleural processes. THE CANADIAN ENTOMOLOGIST DECEMBER, 1934 270 Can. Ent. Vol. lxvi Plate ii nymphs of aesciina juncea l. and a. subarctica wlk, EXVI THE CANADIAN ENTOMOLOGIST 271 European specimens are in my opinion con- specific but I should hesitate to draw any further conclusions from a comparison of so few specimens, as to whether they represent distinct races or not. Nevertheless the descriptions and figures by European authors (Valle, op. cit. ; Bartenef ’29, ’30a; Schmidt, ’29; Eief- tinck ’29) seem to indicate clearly that the typical elizabetae from Russia and Finland differs somewhat in colour-pattern, though perhaps not structurally, from the form which inhabits more southern parts of Europe. Bartenef (’30b) urges the necessity of a detailed comparison of all three forms, emphasizing the importance of the characters of the accessory genitalia of the male, as .revealed in cleared microscopical preparations. On this question I am not at present able to throw any light. For the present I am following the prevailing view that we have to do with one species but shall employ the racial name elizabetae for both European forms, although my observations on the nymph apply to the form which inhabits central Europe. The life history of Aeschna subarctica elizabetae has been described at some length by Munchberg (’30) whose account is illustrated by a photograph of the full-grown nymph and some figures of the anal appendages and prothoracic processes. During a visit to Czechoslovakia in 1928 I received two nymphs from the late Dr. F. Ris, who sent them in moist cotton batting, together with an adult male from the same locality, viz., the Black Forest, Wurtemberg, Germany. One of the nymphs, an immature male, was dead on arrival ; the other, a full-grown female, was apparently moribund but revived on being placed in water. This nymph I kept and fed with small earthworms during my homeward voyage and brought safely to Toronto. It was due to transform the following year but, probably owing to long immersion in water of a higher temperature than was natural to the species, it attempted to moult on October 30, 1928. Although emergence was a failure I succeeded in extracting the abdomen and could readily determine that the form of the ovipositor-valves was like that of subarctica and not juncea. In 1931 I visited The Pas, Manitoba, and there, on July 11, I had the good fortune to find a newly-emerged male of A. subarctica with its exuvia. I also found three other exuviae of the same species (2 $ 1 $ ) on July 7, 9 and 10. A. juncea was also present here and had begun to emerge earlier. The exuviae were quite easy to distinguish from those of subarctica by their more obscure colour-pattern and duller lustre. It is thus possible now not only to compare the exuviae of subarctica with juncea but also with elizabetae. The exuviae of typical subarctica (text fig b) differ from those of A. juncea americana in the more polished and conspicuously marked dorsal surface, the pale longitudinal bands on the abdomen being more distinct; in the slightly slenderer abdomen, the still more vestigal lateral spines on seg. 6, the longer and more hooked cerci and the more slender lobes of the labial palpi. Colour brown, a little darker than in juncea, the abdomen more conspicu- ously marked and more polished. Head and thorax, including the legs, con- colorous, except for traces, sometimes obscure, of a pale postocular stripe, which borders the sides of the head and pronotum.

Head and eyes as in juncea; mentum of labium (pi. 11, fig. 4) somewhat less expanded distally, the lateral margins of the wider distal part being less strongly sinuate and not converging distad to the bases of the palpi ; . proximal width equal to a trifle more than three-fifths of the distal width. Palpal lobes more slender than in juncea , being scarcely broader at their bases than the bases of the moveable hooks, slightlv narrowed towards their apices, which are sub- truncate, their outer angles well rounded, the inner angles barely toothed. Pro- pleural processes as in juncea, or a little more prominent, with coarser scales (pi. 12, fig. 12) ; mesopleural processes (fig. 14) decidedly more prominent than in juncea , both obtusangulate. Abdomen slender, slightly narrower than the head across the eyes, reaching its greatest width at segment 6 (or 5), 5-7 being of nearly equal width. Lateral spines on 7 to 9, with a vestige on 6 in the form of a more or less acutangular prolongation of the tergal angle, (pi. 12, fig. 17) not noticeable from above ; spines on 8 reaching two-thirds or three-fourths of the distance to the base of 9 ; those of 9 to the basal third or middle of 10. Para- procts about as long as 9+10, their apices bent inward; cerci two-thirds as long as paraprocts, or very nearly so, their inner margins sinuate, apices tapering more abruptly than in juncea and decidedly incurved in the male ; rudiment of inferior appendage of male adult three-fifths as long as cerci. similar to that of juncea.

The single exuvia which I possess of Aeschna subarctica elizabetac differs from typical subarctica in the. following characters: (1) There are not even vestiges of lateral spines on seg. 6. (pi. 2, fig. 18). (2) The lateral spines on segs. 7-9 are all shorter, those on 8, e.g., extending only about half-way to the base of 9, and those of 9 only about one- fourth the length of 10 (fig. 7). (3) The paraprocts are scarcely as long as segs. 9+10 and are not in- curved at their tips (fig. 7).* (4) The palpal lobes are broader, being intermediate between those of juncea and subarctica. (See figs. 3 and 4). (5) The colour pattern is more uniform, the pale and dark longitudinal bands of the abdomen being as indistinct as in juncea americana. *Tlhey are, 'however, desicrilbed 'by Munchberg (’28) as being longer than segs. 9-1-10 and his figure shows 'their apices as decidedly bent inwards, THE CANADIAN ENTOMOLOGIST DECEMBER, 1934 274 These differences between the nymphs of Aeschna subarctica subarctico and A. subarctica elizabetae appear to support the view that these forms repre- sent different species rather than mere geographical races, but, with so little material of elizabetae for comparison, it is impossible to arrive at a definite conclusion. references.

FISHER, Biureiaiu of Entomology laffiid 1 Plant Quarantine, Uiniilteid! States iDepairjtimienit .oif Agriculture. Specimens of an unknown Anobiid beetle infesting the woodwork of a house in Ontario were submitted to me by Prof. A. W. Baker, Ontario Agricul- tural College, Guelph, Ontario, for identification. It appears necessary to propose new names, both generic and specific, by which the species may be known. Platybregmus new genus. Body elongate, subcylindrical, prothorax deeply excavated beneath, for the reception of the head, which is received in repose upon the anterior coxae. Head feebly margined in front and strongly carinate around antennal bases; last joint of maxillary palpus elongate oval, pointed, very little wider than preceding joint; last joint of labial palpus broadly triangular, inner side slightly rounded, much wider than preceding joint. Antenna 11-jointed; first joint robust, oblong; second smaller and shorter ; third to eighth short, narrow, not serrate ; ninth and tenth compressed, elongate triangular; eleventh compressed, elongate oval; ninth, tenth, and eleventh joints united nearly as long as the preceding joints. Eyes moderately large, rather strongly convex. Prothorax strongly convex, narrower than elytra, lateral margins obliterated, except toward base. Elytra striate punc- tate. Front and middle coxae widely separated, the antennae received between them. Prosternum flat, truncate behind, and longitudinally carinate. Metaster- num not or scarcely excavated in front. Posterior coxae narrow, nearly parallel, not dilated internally, but more or less sulcate for the reception of the femora. Femora not clavate. Tibiae rather slender, not compressed nor produced externally at apices; tarsus one-half as long as tibia, the first joint as long as the following two joints; tarsal claws slender, not toothed at base. Abdominal segments free, sutures distinct; first ventral segment as long as second; third, fourth and fifth shorter and subequal in length. Genotype. — Platybregmus canadensis , new species. This genus belongs to the tribe Anobiini, and is related to Hadrobregmus Thomson, but it differs from that genus in having the prosternum longitudinally carinate, the pubescence on the dorsal surface longer and more erect, and the lateral margins of the pronotum obliterated, except near the base. Platybregmus canadensis n. sp. Uniformly dark reddish brown and subopaque. Head deeply sunk within the prothorax, the eyes partially covered in repose ; front nearly flat, rather densely granulose, the granules distinctly separated, rather densely clothed with moderately long, semi-erect, brownish hairs.

ADDITIONS AND CORRECTIONS TO “A LIST OF THE .BUTTERFLIES OF MAINE.” BY C. E. DOS PASSOS AND E. P. GREY, Menidham, N. J. — Liinioollin, 'Nebraska. A few errors and omissions in the list of Maine butterflies as published in the Canadian Entomologist in August 1934, should be corrected as follows : Papilio troilus Linnaeus. York Beach (Farquhar). Eurymns eurytheme (Boisduval). A yellow specimen was taken at Passa- dumkeag. Fairly common this fall. Danaus menippe fumosus (Hulst). Lincoln (Clayton). Phyciodes nycteis (Doubleday & Hewitson). For nyteis read nycteis. Polygonia progne (Cramer). For I-argenteum read L-argenteum. Basilarchia arthemis (Drury). Recent records indicate a partial second brood Basilarchia astyanax (Fabricius). York (Farquhar). Strymon Ontario (Edwards). The record cited has been found to be in error for acadica (Edwards), which leaves no Maine record. Incisalia inis (Godart). Further records are needed to establish the authen- ticity of the old ones. This species has not been reported for many years. The specimen in the Fernald collection at Orono is irus , but has no data. Incisalia lanoraiecnsis Sheppard. This recently described species (Can. Ent. June, 1934) is found on the bogs near Lincoln about thickets of young spruce. May. Lycaena epixanthe amicetus (Scudder). Passadumkeag, June-July. Plebejus saepiolus Bdv. Insulanus Blackmore is a race from Vancouver Is., B. C., and the Maine form should probably be referred to saepiolus, pure and simple. Polites peckius (Kirby). Common. June-July. Polit es mystic (Scudder). Not rare. June-July. IyXVI THE CANADIAN ENTOMOLOGIST 279 RECORDS OF SIPHUNCULATA AND MAELOPHAGA FROM CANADIAN HOSTS. BY GORDON B. THOMPSON, British Miuseaim (Naît. Hist.), London. The following records are based on material collected, for the most part, by Mr. W. E. Whitehead of the Department of Entomology, Macdonald College, McGill University. For the opportunity of examining this material I am indebted to Sir Guy Marshall, F.R.S., Director, The Imperial Institute of Entomology, London. Previous records of lice taken from hosts in the Dominion of Canada are very few although there are numerous papers on these parasites found on birds and mammals of the United States which also occur in Canada. The following papers may be listed as containing records of lice from Canadian hosts : Baker, A. W., (1915), Canad. Ent., XLVII, pp. 237-241. ( Baker, A. W., (1919), Rept. Can. Arct.

BY G. CHAGNON. University of Montreal. Among some beetles kindly determined recently for the writer by Dr. H. C. Fall, was found a specimen of the European Staphylinid Dele aster dichrous Grav. As the species does not appear to have been recorded before from North America, I am giving below a short description of the insect, by which it may be recognized. Deleaster dichrous Grav. Length 6.5 mm. Color reddish brown except head and abdomen which are blackish. Prothorax slightly cordate, narrower pos- teriorly than in front, with an impression on each side and another, transverse, on the middle near the base ; abdomen smooth. Two specimens taken by Rev. Bro. Jules, at Longueuil, near Montreal, Que., in June, 1934. Mailed Monday, Dec. 31, 1934. New SPENCER Type No. 30 MICROSCOPE For Semi-Research 1 HIS large microscope, same size as No. 3, described in October issue, is designed to meet the de- mand of research and medical workers for a research microscope of moderate cost. This No. 30 Microscope is offered with the low type fine adjustment as its out- standing new feature. As the il- lustration shows, it is beautiful in proportion and perfectly in balance. It is built sturdily with exacting precision insuring a long life of faithful service. LOW FINE ADJUSTMENT This low type fine adjustment enables the microscopist to operate fine adjustment buttons with his hand resting comfortably on the table. The construction is the same as that of Microscopes Nos. 5 and 3. Patent applied for. BASE, PILLAR, ARM AND STAGE Compared to similar medical and laboratory microscopes No. 30 has a larger base and pillar, larger arm, larger plain stage, it being 125mm. x 125mm. instead of iiomm. x 105 mm. The free distance from the optical axis to the inner curve of the arm is increased to 100mm. giv- ing greater space for manipulation of specimens. ACCESSORY EQUIPMENT The substage is the patented Spencer fork type which holds the con- denser securely in correct position. It is actuated by rack and pinion. FINISH The instrument is finished in rich lustrous black, beautified by chro- mium plated objectives, adjustment buttons and other metal parts. It is furnished in a hardwood cabinet with receptacles for the separable parts.
