All of the objectives are accurately centred and are parfocalized in accordance with the tube length of the instruments; they are carefully made, polished and fitted into their metal cells. The mechanism and metal parts of these microscopes are the product of skilled craftsmen accustomed to turning out a finished article in which they take great pride. The building of Steindorff Microscopes is not on a production or piece work basis, and each in- strument when finished receives a thorough ex- amination and is tested by expert microscop- ists familiar with the making of the necessary detailed tests in an instrument of this kind. Considerable attention has also been given to design and finish, together with durability under long periods of use, resulting in instru- ments which we believe to be second to none , optically , mechanically , in appearance and price. We cannot too strongly recommend the pur- chase of Steindorff Microscopes. Steindorff Microscopes Cost Less Write For Descriptive Bulletins and Prices Dept. B 10.

ORIEEIA, JANUARY, 1930. No. u THE FIRE BRAT, THERMO BI A DOMESTIC A PACKARD, (EEPISMIDAE) IN CANADA. BY G. J. SPENCER, University of British Columbia. The Fire Brat, Thermobia dome stic a Packard, seems to have been in Eastern Canada for some time. Since, as its nick-name indicates, it is a heat- loving species, favouring steam-heated buildings, it has probably been established in the country for a long time although the records of its distribution in Canada are few and are all fairly recent. My records of the distribution of the species across the country are as- follows : — • In the winter of 1915/16 I investigated an outbreak in a hospital in Tor- onto-, where it occurred in considerable numbers in food and passenger elevator shafts running to the basement. Recommendations for its control were advo- cated and no further complaints were received. The next infestation was reported to me when I was out of the Province of Ontario in winter 1923/24, by Mr. Caesar who- found it in great numbers in certain bake-houses in Guelph. Coming westwards, Dr. O’Donoghue of the University of Manitoba re- ported it to me in the summer of 1925 as having been found the previous winter for the first time, in the buildings of the University in Winnipeg, where a few specimens had been captured. In the winter of 1926/27 I received a complaint about it from Saskatoon where it had just been picked up for the first time, in considerable numbers. During the winter of 1927/28 I was again in Toronto- and made a point of visiting the hospital where it had been in 1916. It was still present in the hospital but only in one of the storerooms in the basement. A thin brick wall separated the storeroom from the kitchens, whose extensive cook stoves lined practically the whole length of the wall. While no fire brats were found in the kitchens, they occurred freely on the wall in the other room which was warmed by the heat o-f the stoves. None were found in the elevator shafts where they had been found twelve years previously. The insect was found also-, though in very limited numbers, in the basement of the Biology building of the University of Toronto. However, in the basement of the Royal Ontario Museum it occurred in great numbers in several rooms, on the sides warmed by steam pipes. This infestation in the museum was particularly interesting, in that the insects were of a markedly darker pattern than those found hitherto — ^exhibiting, apparently, a melanic race. Sufficient work has not yet been done on this race to show that it is anything but a colour variation. It has been kept continuously in cages since that time both in pure and in mixed colonies, and the dark colour pattern still persists. Experiments are under way to prove whether the two strains will in- ter-breed or not. I am of the opinion that they will. 2 The: CANADIAN ENTOMOLOGIST JANV I93O. All other records, before and after this one of the museum, are of the lighter colour pattern. During this same period of 1927/28, I found it both in Ottawa in steam heated public buildings, and in Guelph in the same bake-houses where Mr. Caesar had taken it in 1923/24. In the autumn of 1928 I got the first record of it in Vancouver where it had made its appearance in small numbers in laundries of one of the hospitals. Officials declared that this was the first time that it had occurred there. I have worked out the life-history and reactions of this insect fairly thor- oughly and the findings are being published elsewhere. Nevertheless, a few comments are in order here. It is a creature of circumscribed surroundings, fav- ouring hot, damp locations such as the neighborhood of steam pipes and furnaces in dark basements. Temperatures of 90° F. to no° F. suit it best. It is negative- ly heliotropic, especially in early instars. It passes through at least fourteen in- stars before becoming adult and apparently can moult indefinitely for the rest of its life if necessity arises,. Its particular foods are farinaceous substances, cer- tain animal and vegetable glues and most particularly, dried lean meat. Possibly its greatest point of life-history interest is that there is no copulation between sexes; fertilization occurs by the female picking up from the floor a spermatophore deposited by the male after a more or less prolonged “love dance,” thus bringing to mind the somewhat similar habits of Geophilus of the Chilopods and certain tailed Amphibians. It is the simplest type of fertilization amongst insects, being even more primitive than that of some of the Tettigoniidae. When present in large numbers, it proves a pest of considerable importance, •attacking many starchy products, surfaces of certain glazed papers, and glues. When it occurs in a dwelling house, its habits are very much like those of the German cockroach. STUDIES IN THE SCARABAEIDAE (IV).* BY W. J. BROWN, Ottawa, Ont. Aphodius smith! n. sp.

This species falls near hicanus in Horn’s table. Its closest ally is l ec ont ci in which the elytral intervals are punctate and accessory spinules are absent. Ochodaeus gnatho Fall. $ Ochodaeus nimius Fall. Ochodaeus nimius Fall is evidently the female of gnat ho. I have seen speci- mens of both from the type locality, Mesille Park, N. M. In the male, the basal portion of the mentum is produced ventrad to form a thin, wedge-like process, the IvXH. THE: CANADIAN ENTOMOLOGIST 5 mandibles are elongate, the head wider, and the front slightly more concave. In the female, the mentum bears no process and the mandibles are much shorter. There is perfect agreement in all other characters. As in some other species, the size in quite variable; the series at hand measures from 5.3 mm. to 7.6 mm. in length. In all species of Ochodaeus that I have seen, the sexes may be separated by the form of the abdomen. In the males, the median line of the abdominal venter is broadly and slightly but distinctly flattened. In the females, the abdomen is even- ly convex. OchrosicLa subvittata n. sp. Male. Length 11-14 mm.; width 6-7.7 mm. Oval, moderately convex. General color testaceous ; the head between the eyes, extreme apices of femora and tibia, and external margins of anterior tibiae black; clypeus, apical segment of abdomen, and tarsi rufous ; pronotum with a faint rufous cast, a small spot near each lateral margin and sometimes a small area on each side of middle near apex slightly darker; each elytron with internal third and humeral umbone brownish this dark area not sharply limited and sometimes extended to include the entire disk except a broad submedian area which may be interrupted; pygidium dark brown or blackish, usually paler at base and apex ; venter pale testaceous, without a rufous cast. Entire surface except the clypeus with conspicuous yellow hairs. Head three-fifths as wide as the pronotum ; the clypeus two-thirds as long as wide, the sides parallel in basal half, the apex truncate, the angles very broad- ly rounded, densely punctate, the punctures coarse and very shallow ; front mod- erately coarsely and closely punctured. Pronotum two thirds as long as wide; rather coarsely, moderately closely punctured, the punctures somewhat irregular in distribution, the median line impunctate at middle; the basal marginal line fine, usually broadly interrupted at middle. Elytral sculpture of the usual type. Penultimate abdominal segment slight- ly but distinctly longer than the two preceding united. Holotype. — $, Choctaw Co., Okla., July, (G. A. Bieberdorf) ; No. 3112 in the Canadian National Collection, Ottawa. Paratypes. — 8 S , same data. This species is closely allied to nigricolUs and appears to differ only by the paler color, the slightly larger size, and the longer pentultimate abdominal segment. Before me are four specimens of nigricollis from the series described by Mr. Buchanan (Ent. News, XXXVIII, 166). In these, the length of the penultimate abdominal segment is equal to that of the two preceding united and the color is much darker ; the pronotum and ventral surface are distinctly rufous and the ely- tra are reddish-brown throughout. Euphoria fuscocyanea Csy. This is evidently a southwestern subspecies of fidgida Fab. and is usually confused with the latter in collections. I11 fuscocyanea the abdomen and pygidium do not always lack tomentose spots as in Casey’s single type ; these spots are usually more or less developed and are sometimes as numerous and as large as in typical fulgida. Nor is fuscocyanea always blue throughout ; in some examples, only the elytra have a. slight bluish cast. In the Wichita Mountains of Oklahoma, fuscocy - 6 THE CANADIAN ENTOMOLOGIST JAN. y 1930. anea occurs abundantly with typical fulgida, and the specimens I have collected there present a perfectly graded series from typical fulgida to well characterized fuscocyanea. RECORDS OF HETEROPTERA FROM NOVA SCOTIA. BY J. R. DE LA TORRE-BUENO, White Plains, N.Y. Mr. C. A. Frost, the coleopterist, to whom of recent years I have been indebted for many interesting and, indeed, rare Heteroptera, has again favored me with some unusual species taken by him this summer (1929), in Nova Scotia. Portaupique, so I learn from Mr. Frost, is on the North shore of Minas Basin, 30 miles west of Truro; Westchester is up in the hills at a lake in the spruce woods. As might be expected, the general character of the bugs is northern, as in- dicated by the presence of the rare Dictyonota tricornis var. americana Parshley, Corizus crassicornis and Nabis f lav omar ginatus. Otherwise, the species are those usual in North Eastern North America, largely of the Transition Zone, such as the common and ■widespread Eusckistus tristigmus and Cosmopepla bimaculata. The species before me are: Eusckistus tristigmus Say, 2 from Portaupique, July 24 and 25 respectively; and 2 from Westchester, July 31. These are new localities for the species. Cosmopepla bimaculata Thoms., 3 from Portaupique, July 23; and 2 from Penobsquis, July 20. These also are new localities. Me ad or us lateralis Say, 1 specimen from Portaupique, July 24, a new locality and the second record from Nova Scotia. Podisus serieventris Uhler, 1 from Portaupique on July 23 and another from Westchester on the 27th, both additional reports from Nova Scotia, from new localities. Podisus modestus Dallas, Portaupique July 22, a single specimen from a new locality. Corimelaena nitiduloides Wolff, not heretofore recorded from Nova Scotia, 1 from Portaupique, July 27. Sehirus cinctus P. B., 1 from Portaupique, July 21, a new locality. Corizus crassicornis E., Portaupique, one on July 27 and another on the 22nd; new locality. Ligyrocoris sylvestris L, Westchester July 25. Dictyonota tricornis var. americana Parshley, 1 from Portaupique July 27 and another from Westchester, July 25. These are two new localities for Nova Scotia, and apparently the third reported records. Corythucha elegans Drake, 4 from Portaupique, July 27. It would seem that this is the first record of this species from the Province. Ant hoc oris borealis Dallas, one adult and one nymph from Portaupique, July 22. These are unusually large for the species. Another new locality. Pagasa fusca Stein, Portaupique, 2 taken on July 27 and one on the 30th. Does not seem to be known from N. S. Nabis flavomcr ginatus Scholtz, a specimen from Portaupique, July 22; a new locality. I, XII. T HIv CANADIAN ENTOMOLOGIST 7 Gerris marginaius Say, male and female from Portaupique, July 31. Gerris rufoscutellatus Eatreille, one teneral specimen, July 31. Saida coriacea Uhler, 1 of the shortwinged form, Penobsquis, July 20. Saldula orbiculata Uhler, same data, one specimen. Microvelia americana Uhler, Portaupique July 27. The five species above appear not to have been reported from Nova Scotia. All the previous records of these species and the absence of certain of them, have been derived from Parshley’s paper in Proe. Acadian Ent. Soc., for 1922, No. 8, pages 102-3, entitled “Records of Nova Scotian Hemiptera Heterop- tera.” NEW WEST INDIAN BUPRESTIDAE AND CERAMBYCIDAE. (COEEOPTERA). BY W. S. EISHER, Bureau of Entomology, U. S. Department of Agriculture. In working over material received for identification from S. C. Bruner and G. N. Wolcott, the following new species were found. Ohrysobothris haitiensis n. sp. Pemale. — Small, short, rather robust, feebly convex, and Subopaque ; above dark brown, with a rather distinct olivaceous reflection, and each elytron orna- mented with small, round, depressed bright green spots as follows : one in basal depression, one at middle, and the other at apical third.

Anterior tibiae feebly arcuate, slightly flattened on inner surface, and without any dilatations ; middle and posterior pairs straight and subcylindrical. Length, 5.6 mm. ; width, 2.8 mm. Type locality. — Manville, Haiti. Type. — Cat. No. 42162, U. S. N. M. Described from a unique female collected at the type locality, April 5, 1926, by G. N. Wolcott. This species is allied to sexfasciata Schaeffer and insulana Fisher. In my table to the species of this genus in A Revision of the West Indian Coleoptera of the Family Buprestidae (Proc. U. S. Nat. Mus., vol. 65, 1925, Art. 9, p. 93), this. species runs to number 17, but it differs from sexfasciata, as well as insulana, by being of a uniform olivaceous brown color above, and each elytron is ornament- ed with three round, deeply depressed bright green spots. Taphro cents bruneri n. sp. Rather broadly elongate, strongly attenuate posteriorly, moderately con- vex above, strongly shining, uniformly brownish black above and beneath, with a distinct aeneous tinge (head and pronotum slightly more olivaceous in some examples), and without pubescent spots. Head distinctly narrower than pronotum at bace, and when viewed from above is transversely truncate in front, and broadly, feebly concave at middle ; front wide, feebly, broadly concave between the eyes, the lateral margins parallel, and with a narrow, vague, longitudinal groove extending from the epistoma to occiput; surface densely, vaguely granulose, coarsely, sparsely, irregularly punc- tate, and irregularly clothed with a few very short, cinereous hairs ; eyes large, elongate, moderately convex, more acutely rounded beneath than above, but not projecting beyond sides or front of head; epistoma slightly elevated, nearly serni- cireularly emarginate in front, and the surface finely reticulate. Pronotum moderately convex, nearly twice as wide as long, apex dis- tinctly narrower than base, and widest near basal third ; when viewed from above the sides are feebly, arcuately expanded to just behind the middle, where they are broadly rounded, then vaguely narrowed to the posterior angles, which are IvXH. THE CANADIAN ENTOMOLOGIST 9 obtusely angulated ; anterior margin vaguely rounded ; base transversely truncate to middle of elytron, then extending obliquely backward to the scutellum, in front of which it is feebly, arcuately emarginate; surface with a few vague, irregular depressions, finely, densely granulose, coarsely, sparsely, irregularly punctate, and clothed with a few short, inconspicuous hairs toward the sides. Scutellum triang- ular, rounded in front, strongly acuminate behind, and the surface nearly smooth. Elytra about as wide as pronotum at base, and equal in width at base and middle ; humeral angles obtusely angulated ; sides broadly, arcuately constricted in front of middle, broadly, arcuately expanded at middle, then strongly, obliquely narrowed to the tips, which are broadly, conjointly rounded, and coarsely, 'irregu- larly serrate ; humeri rather strongly developed ; disk rather strongly convex, with broad, shallow, tranverse basal depressions, but without lateral carinae; surface with indistinct rows of coarse, shallow punctures, the punctures distinct in the basal region, but becoming indistinct toward the apex, the intervals nearly smooth, vaguely rugose, and very sparsely clothed with short, inconspicuous hairs.

REVIEW OF EPHEMEREELA NYMPHS OF WESTERN NORTH AMERICA (EPHEMEROPTERA)* BY G. STUART WARILY, Ottawa, Ont. Studies by Eaton (1884), Dodds (1923) and Needham (1905, 1927) have contributed much to our knowledge of the nymphal forms of Ephemerella occur- ring in Western North America. Needham’s recent paper on “The Rocky Moun- tain species of the Mayfly genus Ephemerella” contains a valuable discussion of the nymphs of that region and ils the first attempt to treat of the species in a comparative manner. Nymphal collections made by Dr. J. McDunnough in connection with his studies on the Mayfly fauna of Southern Alberta and the Montana and Yellow- stone regions, have contained further undescribed nymphs pertaining to recently described species of Ephemerella, also many nymphs of the species described by Eaton, Dodds and Needham. The writer is indebted to Dr. McDunnough for per- mission to study this material and for the helpful suggestions he has made dur- ing the course of this study. Of the thirteen species of Ephemerella described from Western North America the nymphs of ten have been studied. The nymph of E. infrequens McD. is not definitely known and both nymph and adult of E. molli tia Seemann, des- cribed from Southern California, are unrecognized but probably fall close to inermis Etn. Material of E. grandis Etn. has not been available for study but the descriptions of Eaton and Needham are sufficient to place the species readily. The nymphs of this genus offer a variety of characters on which they may be distinguished. Of importance among these are the presence or absence of gills on the third abdominal tergite ; the development of cephalic, thoracic and abdominal spines or tubercles ; the presence or absence of a frontal shelf on the head ; the degree of f lattening and prolonging of the lateral region of the abdom- inal segments. ; the relative lengths of the setae and their ornamentation ; the relative slenderness of the legs, particularly the shape and nature of the front femora; the spining of the tarsal claws. Color characters when judiciously used to supplement structural differences have proven valuable in separating closely allied species but the color pattern in some species (e. g. inermis and coloradensis ) has been found to vary considerably. The structure of the mouth parts, employed so extensively by Morgan in the separation of certain eastern species of Ephemer- ella, has been found less valuable. A careful study of the mandibles has shown slight differences. The maxillae are in general very similar but the maxillary palpi provide some characters. The form of the labrum, labium and hypopharynx does not appear to vary appreciably except in distantly related species. While the mouth parts do provide some characters their structure has been given secondary importance in the present diseussiilon in favor of more conspicuous modifications such as abdominal spining,, leg structure and form of head. Most of these latter characters are recognizable in the accompanying photographs which also indicate general form, relative size and color pattern. The finer structural details aTe depicted by line drawings. * — Contribution from the Division of Systematic Entomology, Entomological Branch, Dej>artment of Agriculture, Ottawa. I, XII. THE CANADIAN ENTOMOLOGIST 13 Extensive nymphal modifications have led to the consideration of sub- generic units based on nymphal structures correlated with slight genitalic and venational characters in the adult. Needham (1927) gives a key to the sub-genera, of Ephemerella as he has defined them. The genus Chitonophora Bengtsson, 1909, is considered synonymous with Ephemerella Wish., 1862. The nymph and adult of E. aronii Etn. are typical of Ephemerella (see description below). In other American forms the characters mentioned for Chitonophora intergrade so perfectly with those of Ephemerella as to establish a perfectly gradual series. The following key based on full grown nymphs will separate the species discussed herein. ■ KEY TO WESTERN NORTH AMERICAN EPHEMERELLA NYMPHS i. Gills borne on abdominal segments 4-7 2.

Abdominal spines more produced; legs longer with femora and tibiae more slender (PI. II, fig. 5) coloradensis Dodds. Ephemerella hecuba Etn. PI. Ill, fig. 4 This large (length 14 mm.) much flattened nymph is readily recognized by the long saw-like lateral expansions of the abdominal segments. The gills are lacking on the thiiird segment (the right gill is missing from the fourth in the specimen illustrated in PI. Ill, fig. 4) and the head is modified to form a broad, entire frontal shelf. The nymph has been described and figured by Eaton and Needham ; the latter adds collecting notes. The adult is unknown but the nymph has been recorded from the following localities: Provo River, Utah, July 20; Earner River, Yellowstone Park, Wyo., August 8, 1921 (Needham) ; Colorado (Eaton). The writer has studied material from Rocky Canyon, , Bozeman, Mont., August 9, 1928 (J. McDunnough). Ephemerella margarita Needh. PI. I, figs. 5a, 5b ; PI. Ill, figs 7, 8. This is the only other species from this region which has the first pair of gills borne on the fourth segment. It is much smaller than the preceding species and lacks the huge lateral abdominal expansions and has no frontal shelf (PI. I, fig. 5a) on the head. The front legs are slender and smooth and typically band- ed (PI. I, fig. 5b). The abdominal color pattern varies somewhat, two color phases being shown :i'n the accompanying photographs (PI. Ill, figs. 7, 8). In mature specimens the tails have a dark cross band near the middle. The nymph has been taken by Needham in Utah “in Box-Elder (Brigham) Canyon, in Web- er River at the Devil’s Slide, ait Wanship, and at several poiilnts along the Provo River.” The writer has studied the following material: Firehole River, Lower Geyser Basin, Yellowstone National Park, Wyo., July 29, 1928; Rocky Canyon, Bozeman, Mont., Aug. 9, 1928; Belly River, Lethbridge, Alta., Aug. 15, 1928 (J. McDunnough). The jBozeman specimens are the ones illustrated. The adult of this species is. not yet known. Ephemerella doddsi Needh. , PI. Ill, figs. 5, 6. This large, stout bodied, uniformly colored nymph bears a large horse- shoe-shaped sucking disk on the ventral surface of the abdomen (PI. Ill, fig. 5)- The front femora are stout with their anterior margin tuberculate and the head bears a frontal shelf which is notched at the sides for the reception of the an- tennae. The dorsum is entirely without spines or tubercles and the gills are of the normal type placed on segments 3-7. The abdominal segments are slightly expanded laterally with their posterior-lateral angles very slightly caudally pro- duced. The structure of the nymph of this species ils fully treated by Eaton (1884) and Dodds (1923) under the name B. grandis adds further descriptive and collecting notes. Needham (1927) refers this species to the sub-genus Baton - ella Needh. on the basis of the peculiar frontal shelf. LXII. THE CANADIAN ENTOMOLOGIST 15 The species has been recorded from Colorado, Idaho (Eaton) ; Colorado (Dodds) ; Utah, Montana, Washington, California (Needham). The specimen illustrated in Plate III is from Sage Creek, Elkhorn Ranch, Gallatin Canyon, Montana, Aug. 4, 1928 (J. McDunnough) and specimens of full grown nymphs are also at hand from the Alberta localities, Pass Creek. Waterton, Aug. 21, 1928 (J. McDunnough), July 27, 1929 (J. H. Pepper) ; Banff, Aug. 29, 1928 (J. McDunnough) . Ephemerella inermis Etn. PL II, figs. 7, 8. This is a rather slender species having the head devoid of spines or tubercles, the front femora smooth and slender, the abdomen without dorsal spines but with its segments with their lateral margins expanded and flattened with the hind angles of the gill-bearing (3-7) segments prolonged. In mature specimens the legs and tails are blackish banded, the head and thorax mottled with light and dark and the abdomen brownish with paler markings most pronounced on tergites 5-6. The accompanying photographs (PL II, figs. 7, 8) illustrate two color phases of this rather variably patterned species. The species has been recorded from Denver, Arkansas Canyon and Color- ado Springs, Colorado (Eaton). The present identification is based on a series of full grown nymphs from Yellowstone Lake, Wyo., July 23, 1928 (J. McDun- nough) taken at the same time and place as large series of adults of inermis. It might be noted that the nymph of infrequcns McD., which is unknown is probably very similar to inermis Etn. judging by the close structural resem- blance in the adults. Needham’s description of inermis nymphs may refer to infrequens since hits determination is based on a misidenti fication of the adult ( vide McDunnough, Canadian Entomologist, LX, 238, 1928) ; also Dodds Bphem- erella nymph No. 2 may be infrequens McD. ( inermis Needh. nee. Etn.). Ephemerella heterocaudata McD. PL I, figs. 3a, 3b, 3c, 3d; PL II, figs. 4, 4a. A series of small blackish nymphs taken in the Firehole River, Yellowstone National Park, Wyo., July 22, 1928 (J. McDunnough) are referred to this species ( vide McDunnough, Canadian Entomologist, LXI, 171, 1929). Though not bred from individual specimens the association of nymph and adult is quite cer- tain since both stages present the much lengthened middle seta, a character appar- ently peculiar to this species. The full grown nymph is described as follows : Length of body 6-7 mm. ; lateral setae 3 mm. ; middle seta 8 mm. Head rounded and smooth as in tibialis. Maxillary palpus with three joints' of equal length, the third more slender than basal two. Prothorax slightly more than twice as broad as long with lateral margins broadly arcuate. Legs rather short, femora more flattened than in tibialis but quite smooth; legs fringed with fine dusky hairs.. Gills on abdominal segments 3-7. the first pair normal, not forming an operculum. Tergites 2-9 each with a median pair of strong black slightly incurved blunt tubercles, becoming gradually longer and further apart from segments 2-7, shorter and closer together on 8-9, and all beset with fine black spines. Abdominal segments not flattened laterally and with the posterior-lateral 1 6 THE CANADIAN ENTOMOLOGIST JAN., IQ30. WESTERN EPIIEMEREEEA NYMPHS Plate: Can. Ént. Vol. lxiî.

General color (in alcohol) dark brownish, the head blackish especially on the front. Legs brown throughout, not banded with pale as in tibialis and aronii. Abdomen dark brown above, the venter paler brown with a median fuscous streak and a row of narrower more sharply defitned brownish dashes on either side. Setae brownish with the incisures darker. Ephemerella spinifera Needh. PI. Ill, figs. 1, 2, 3. This strikingly modified nymph is easily recognized by the long acute- spines on the head, thorax and abdomen (PI. Ill, figs. 1, 2, 3). Gills of the usual type are borne on abdominal segments 3-7 and the segments are laterally expanded and posteriorly produced. The nymph is recorded by Needham from Montana and Utah. The specimen illustrated is from Gardiner River, Yellowstone National Park, Wyo., July 26, 1928 (J. McDunnough). The species appears to be rare and the adult stage is unknown. Ephemerella grandis Etn. This species appears to be related to spinifera Needh. possessing a some- what similar arrangement of spines. The characters mentioned in the above key will however readily separate the two forms. The Washington specimens figured by Eaton (1884, PI. 38, figs, n-15) to which Needham applies the name grandis would appear to differ slightly from the Utah specimens figured and described by Needham (1927) particularly in respect to the m esc thoracic spining and it is possible that Eaton’s nymphs represent a closely allied species.

Chitonophora Aronii Etn., Ulmer, Stett. Ent. Zeiit., 81, 120, 1920. Ephemerella norda McD., McDunnough, Can. Ent., LVI, 223, 1924. Adults of a species of Ephemerella bred from nymphs by Mr. W. J. Brown at Bradore Bay, Quebec Labrador, July 27, 1929, have been identified by Dr. J. McDunnough as conspecifx with E. norda McD. known only from Nordegg, Al- berta and the Pribiloff Islands, Alaska. Dr. P. Esben-Petersen on comparing the Bradore Bay material with a metatype of aronii Etn, from Europe, is of the opin- ion that the two are synonymous ; also that aurivillii Bgtss. should fall to aronii Etn. in which latter view he is supported by Dr. G. Ulmer. The synonymy there- fore will stand as above. The description of the full grown nymph of aronii is as follows : Length of body 9-10 mm. ; length of setae 5-6 mm. Head rounded, smooth, without dorsal or facial spines or tubercles and without a broad frontal shelf. Clypeal margin truncate. Maxillary palpus with basal joint slightly longer than two apical joints combined, the second joint shortest, half the length of the slender third. Prothorax slightly more than twice as broad as long, the lateral margins narrowly explanate. Legs similar in form to tibialis. Gills normal on segments 3-7. Tergites 2-7 each with median pair o£ i8 THE) CANADIAN ENTOMOLOGIST JAN., I930. very slightly elevated minutely spined projections on posterior margin (PL I, f:ilg. 4b). Abdominal segments 4-9 laterally expanded and flattened with their posterior-lateral angles produced (PL I, fig. 4a; PL II, fig. 6). General color (in alcohol) rather light brown. Head with darker brown on face and somewhat mottled on vertex, a small pale area between compound eye and lateral ocellar spot. Femora pale brownish with apices narrowly pale, front and mid-femora with a faint incomplete pale sub-apical ring; tibiae with a broad sub-basal and narrower apical pale band, the hind tibiae with the sub-basal band very broad ; tarsi with narrow basal and broader apical pale bands. Thorax light brown with a few small scattered darker brownish spots. Abdomen light brown- ish, each tergite with a pair of rather widely separated dark brownish quadrangu- lar areas most prominent on segments 3-7. Flange-like margin of abdomen pale brownish with a dusky spot on the margin of each segment. Setae pale, a few segments obscurely darker and the apical 4 or 5 segments black. Ephemerella tibialis McD. PL I, figs, 2a, 2b, 2c, 2d; PL II, figs. 1, 2, 2a. Nymphs of a rather slender, small, blackish species of Ephemerella taken at Banff, Alberta are associated with adults of tibialis McD. The nymph is des- cribed as f ollows : Length of body 7-8 mm. ; length of setae 4-5.5 mm. Head rounded, smooth, without dorsal or facial spines or tubercles and without a broad frontal shelf. Clypeal margin entire, very broadly arcuate. Max- illary palpus with basal joint sub-equal to two distal joints combined. Prothorax twice as broad as long, lateral margins parallel. Legs rather short, front femora slender, smooth with a few scattered fine spines. Gills normal, on segment 3-7. Abdominal segments but weakly expanded at sides ; posterior-lateral angles only slightly produced in segments 4-7, a little more so in 9. Tergites 2-9 each with a median pair of slightly elevated minutely spined projections (not distinct enough to be tubercles) on posterior margin (PL I, fig. 2b). General color (in alcohol) dark brownish, the thorax and abdomen some- times with a narrow median dorsal pale line (PL II, fig. 2). • Legs brownish, femora with an apical and an incomplete sub-apical pale annulus and a small pale spot below at base ; tibiae with a sub-basal and apical pale band ; tarsi narrowly pale at base and apex. Thorax and abdomen dark brownish throughout. Setae alternately brown and pale annulate, the distinctness of the banding varying with maturity of the specimen. This species resembles the nymph of inermis Etn. The latter, however, has the abdominal tergites entirely smooth. Adults have not been bred from the nymphs but full grown nymphs were found common in the Spray and Bow Rivers at Banff, Alberta, Aug. 29-30, 1928 (J. McDunnough) where adults were taken swarming a few days later, so the association appears reasonably certain. Nymphs are also at hand from Sage Creek, Elkhorn Ranch, Gallatin Canyon, Montana, Aug. 4, 1928 and Rocky Canyon, Bozeman, Montana, Aug. 9, 1928 (J. Mc- Dunnough. The illustrations are from the Bozeman material. Ephemerella flavilinea McD. PL I, figs, ia, ib, ic; PL II, 3, 3a. This species has not been bred from the nymph but full giown nymphs Can. Ent.

McDunnough) and in the Yellowstone River, Yellowstone National Park, July 26, 1928 (J. McDunnough). A few days later subimagos of flavilinea were taken in the same places {vide McDunnough — Canadian Entomologist, EXI, 170, 1929). These nymphs have been carefully compared with a co-typic nymph and a series of nymphs of coloradensis Dodds. The close relationship of the adults is borne out by a similar resemblance in the nymphs but constant characters for the separation of flavilinea may be found in the shorter abdominal spines, stouter legs (particularly the mid and hind pairs) and the shorter thumb (PI. I, figs, ic, 6). The full grown nymph of flavilinea is described as follows: Length of body 9-10 mm. ; length of setae 6 mm. Head broad, face flattened between the eyes, vertex usually with a pair of very low tubercles and the face roughened slightly. Maxillae as in heterocaudata. Legs rather short ; the front femora broadened flattened, the posterior margin with a few spines, the anterior margin with numerous tubercles each surmounted by a short stout spine, upper face of femora with scattered wart-like excrescences; tibiae more slender than in coloradensis. Prothorax twice as broad at anterior margin as long, lateral margins slightly diverging posteriorly with a shallow sinus just beyond middle. Gills on abdominal segments 3-7, the first pair of gills not forming an operculum. Abdominal segments with very narrow flat pleural ex- pansions, the posterior angle developed, not prominent, slightly longer in 9. Ter- gites 2-8 each with a median pair of slightly elevated projections (scarcely tuber- cles) on the posterior margin. General color (in alcohol) varying from light to dark brown, the paler specimens more mottled in appearance than the darker ones. Femora with indistinct broad pale basal, median and apical areas ; tibiae more conspicuously banded with pale at base and apex ; tarsi with a single median pale band. Cerci pale narrowly banded with blackish beyond middle and at apex. Epihemerella coloradensis Dodds. PI. I, fig. 6; PI. II, figs. 5, 5a. This species has been described and figured by Dodds (1923) and by Needham (1927).

THE STATUS OF THE jBARN SWALLOW BUG, OECIACUS VICARIUS HORVATH. BY G. J. SPENCER, University of British Columbia. In 1909 I was interested to hear from a farmer in Ontario, that barn swal- lows are undesirable because they harbour bedbugs which spread from their nests to human habitations. Several times since I have heard the same complaint from various sources. In 1926 an instance cropped up in Vancouver where cliff swal- lows nests were systematically knocked down from some public buildings, for the same alleged reason. In summer 1929 I received complaints from three men in the Chilcoti'n that cliff swallows always filled a house with bedbugs towards the end of the season. In one of the instances, the man systematically destroyed the nests of dozens of birds that were very persistent in building on his outbuildings. In all three oases I asked the men if the bugs so introduced, could be accused of actually “biting.” Tw'o claimed that they certainly did “bite” while the third stated that the bugs invaded the premises only after the birds had finished nesting for the season and had migrated, and that he personally, had never been “bitten.” O'wing to the fact that in the first two- instances the homes of the men were in such conditions of neglect that practically any human parasite could (and probably did) flourish there, I was inclined to doubt their statements. In October of this year, Mr. Alan Dus tan of the Entomological Branch, Ottawa, wrote to me, citing an instance in Alberta where certain bugs from swallows’ nests were invading a building and asking if I had any information as to the bugs attacking human beings. According to my findings up to that date, I was forced to declare the case “not proven.” However, I wrote to Mr. Jenkins at Fishburn, Alta, whose house was mentioned, supplying what information I had and asking for full particulars of his infestation. He sent the following very explicit reply, exhibiting a most praiseworthy spirit of investigation : — Sept. 3 “I am sending five specimens of bugs which I believe to have been brought by swallows. All of these have bitten me. Two of them bit at night, the other three I found around the house and I put them on my arm and let them bite before putting them in the bottle. The white one, although he bit, did not get any blood for some reason.” “About the end of July we discovered these insects in the house and on IvXH. THE CANADIAN ENTOMOLOGIST 21 knocking down the swallows nests (about 200 of them) we found they were simply swarming with them. After this they came into the house in thousands and bit us so much we had to move into tents to sleep. They bite just as badly in the day only. of course there isn’t the same chance of them getting on one. They seem to be practically all gone now although there are still odd ones.” The bugs he enclosed were Oeclmcus vicarius Horvath. On making further enquiries around Vancouver, I have since found two men, one an ornithologist of standing and the other a much travelled and exper- ienced forest officer whose findings can be relied on, who have personally been attacked by these insects from swallows nests and have been “bitten.” They state that the infestation lasts only a few days after the host birds have left their nests. In the scanty literature on the subject available to me, I can find no refer- ence to the identity of the birds reported to carry these bugs, apparently the list has yet to be compiled. The birds under censure in the Chilcotin last summer, were Cliff or Eave Swallows — those mentioned in literature are merely “swallows.” SUMMARY It would seem that several species of swallows in North America are hosts of Oeciacus vicarius Horvath, one of the bedbugs. The insects breed freely all summer in the birds’ nests and in early autumn when migration occurs, the bugs scatter from the birds’ nesting areas and invade dwellings where they may at- tack human beings for a few days : the infestation then dies down. In certain in- stances, apparently of very heavy infestation, invasion of dwellings from nesting areas may occur some weeks before the birds leave their nests. CROESUS VARUS (DE VILLARET). (HYMENOPTERA) . BY J. W. BUCKLE, Montreal, Quebec. On August 8th, 1926, I captured a saw fly of the genus Croesus at the flowers of the common parsnip (Pastinaca sativa) at the foot 'of Mount Royal. The only species of this genus listed in the Hymenoptera of Connecticut, List of the Insects of New York, List of the Insects of New Jersey, and in Mar- latt’s “Revision of the Nematinae of North America” (in which he refers to them as the two North American representatives) are latitarsus (Norton) and laticulus (Norton), but the descriptions given did not correspond with the specimen I had taken. Some time afterwards, with the assistance of Mr. A. E. Winn, we located an illustration and description of Nematus varus (De Villaret) in the Annals of the Entomological Society of France, 1832, Vol. 1, page 306, which corresponded with my specimen, and our determination of the species was verified when I found in a collection of Hymenoptera received recently from Hungary a sawfly labelled Croesus varus (De Villaret) which corresponded with my insect and is evidently the same species. 22 THE) CANADIAN ENTOMOLOGIST JAN., I93O. This seems to- be a very rare sawfly in North America, as the only refer- ence I can find to it is in Kirby’s List of the Hymenoptera in the British Museum, where the habitat is given as Europe and North America, with one record only from North America, a male from Nova Scotia collected by Lieut. Redman. The other references to captures were all from Europe. ANNUAL MEETING OF THE ENTOMOLOGICAL SOCIETY OF ONTARIO, 1929. The Sixty-sixth Annual Meeting of the Entomological Society was held at the University of Western Ontario, London, on Thursday and Friday, Novem- ber 2 1 st and 22nd, 1929. The morning and afternoon meetings were held in the lecture amphitheatre of the Natural Science building. On Thursday at the close o-f the afternoon ses- sions the members of the Society and their friends met in the cafeteria and enjoyed an excellent banquet tendered to them by the University of Western Ontario. The Thursday evening meeting was held in Convocation Hall, when Dr. W. Sherwood Fox, President of the University of Western Ontario, acted as chairman and Mr. K. W. Babcock of the United States Bureau of Entomology, delivered an in- teresting address on “The Trend of Ecological Research in European Corn porer Investigations.” After this meeting a smoker was held in the Cafeteria. During the smoker, Dr. John Dearness and Mr. W. E. Saunders entertained the members of the Society and friends with some very interesting reminiscences of the early days of the Society. The meetings were well attended and proved very successful. During the Meetings the following papers were presented : — History and Present Status of Entomology in the Colleges and Universities in Canada. — A. W.

The Canadian Entomologist Back Volumes A few Sets of Back Volumes * Nearly Complete are Still Available. ENTOMOLOGICAL SOCIETY OF ONTARIO GUELPH, ONTARIO, CANADA A LOW-PRICE, PEST-PROOF, INSECT BOX OF STURDY CONSTRUCTION THE HOOD INSECT BOX This box was designed by Professor J. Do*#* las Hood of the University of Rochester and was need extensively as a container for many of the insects collected in the Cornell* Rochester Entomological Expedition through Western Un- ited States in the summer of 1927. Specimens were carried in HOOD BOXES for a distance of 6,000 miles over many of the poorest roada in the country. Often times the bores were mer- ely tossed into the tonneau of the automobile and other luggage piled on top, and yet the specimens came through in perfect condition. The HOOD BOX Is 8%"xl2%*2%', outside dimensions. The pinning bottom is a sugar-cane pulp composition; an excellent substitute for cork. The box is lined throughout with white glased paper and the outer covering is s heavy black water- grain paper. The frame of both box and cover is made from three-ply veneer with interlocked corners which enables ns to make s tight fitting cover which is pest-proof to an extent which is impossible when only cardboard ia used. In all respects the HOOD BOX is of quality construction, very different from other low-price boxes now on the market. SPECIAL FEATURES OF THE HOOD BOX 1. Post-proof. 2. Wooden frame. 3. High shoulder protecting specimens. 4 Excellent pinning bottom. 5 High quality box nt low cost. Price, $1.25 each. Special rates in quantity.
