Papilio machaon var. aliaska Scud. In the proceedings of the U. S. National Museum, 1932, LXXXI, 1-15, Austin H. Clark discusses at some length the racial variability of Papilio machaon in North America, creating what he designates as two new subspecies.

This paper is a result of the study of the Aphodius in the A. cadaverinus (Mann.) group in the collection of the writer. In determining a goodly number of specimens of this interesting group, one new species has conic to light.

Species of suborder Chalastogastra are retained at Washington, identifications being incomplete.

BRACONIDAE.

Identified by C. F. W. Muesebeck, Washington, and by (marked*) G. S. Walley, Ottawa.

In the latter part of May, 1933, larvae of this species were found feeding in the leaves of Hieracium scoueri Hook. Their presence was easily detected by the great distortion caused to the leaves, which were webbed together, particularly at the terminal ends, thus arresting normal development. All were collected at Pullman, Washington, by the writer.

An excellent way to present generic revision is to show the names arranged in annotated check list style. This method stresses classificational position. I believe entomologists in general are becoming more concept-minded and realize the need of improved lower categorical systems and better Code Rules governing the arrangement of their names. In lepidoptera this need is felt strongest. (See note under No. (15) in this article and also the Entomological News for July, Nov. and Dec., 1932, for further discussion.)

At the 30th Annual Meeting of the Entomological Society of British Columbia in March, 1931, I presented a paper entitled “The Oviposition Habits of Rhyncocephalus sarkeni Will.” which was published in the Proceedings of that year. Again in March, 1932, I read another paper before the same society, “Further Notes on Rhyncocephalus sackeni Will.”, which was published in the 1932 Proceedings.

Oblong oval, convex, piceous opaque. Antennae and palpi rufo-testaceous.

Head moderately convex, densely punctate, the punctures across the occiput coarser, those of the front finer and united longitudinally in groups of two or more, single and still finer approaching the clypeus, the clypeus nearly smooth at middle. Clypeus impresseed in front, broadly emarginate, the angles broadly rounded, sides arcuate ; genae obtuse, not prominent.

Thorax convex, one-third wider than long, sides sub-parallel, feebly arcuate, the edges partly hidden when viewed directly from above; angles obtuse, the hind angles especially so; base broadly arcuate, marginal line distinct ; punctures rather coarse and close at base and sides, a little finer in front.

Externally resembling the species of Erythroneura with red dorsal stripe (E. lawsoniana Bk.) more than any member of its own genus. Easily separated from these of course by the submarginal vein and from all Dikraneura by the bright red or orange median dorsal stripe.

The bees now described are of interest for different reasons. The genus Hesperapis, originally described from New Mexico, has been found to be widely distributed over the southwestern States, with eighteen species, two of which come from Lower California.

From the collections of Dr. E. M. Walker, made in 1908 and 1923, of Mr. W. E. Ricker, made in 1931, and my own. Identified by Dr. E. M. Walker.

The occurence of numerous breeding areas of Simulium pictipes in the vicinity of Ithaca, N. Y., led the writer to make an investigation of its biology during the course of a year that he spent at Cornell University, while making a general study of the Simuliidae of the district.

Identified by F. M. Carpenter, Museum of Comparative Zoology, Harvard, Massachusetts.

PANORPIDAE.

I. Panorpa signifer Bks. July 24. G.L.P. Aug. 27. On outside of laboratory.

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 accompanied 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.

In my paper on the nymph of Cinygma integrum (1933, Can. Ent. LXV, 73) there is a rather serious error which I wish to correct. At the time my material was limited to a single nymphal exuvia; now with the mature nymphs and more exuviae at my disposal I find that the peculiar nature of the maxillae, as described and figured in the above paper, was abnormal and probably brought about by contraction occurring during the process of making a slide of the mouth-parts.

The following additions and corrections bring my “Check List of the Macrolepidoptera of Alberta” up to date. The changes in the Eupithecias are based on Dr. McDunnough's revision which appeared in the “Canadian Entomologist,” Vol. 61, p. 59.

Male. Length 8 mm. Black ; the antennae, anterior margin and posterior angles of pronotum, and elytra very dark reddish-brown, almost black; legs reddish-brown.

The development of wings from imaginal discs has been carefully worked out in many forms of insect larvae. Marshall's important paper on te development of the wings of a caddis-fly, Hesperophylax (Platyphylax) designatus Walk. (Zeitschrift fur wissenschaftlicheZoologie, Bd. CV, Heft 4, 1913) is almost the only literature dealing with this phenomenon in the Trichoptera.

The first extensive contribution to a knowledge of the anthomyid flies of North America was made by Francis Walker in 1849, when he published the records of fifty-five nominal species in his list of dipterous insects in the British Museum.

Male. Length 5.8 mm. Reddish-yellow: the legs paler; the front, vertex, a large discal cloud on the pronotum, and the abdomen except apical segment pale reddish-brown; each elytron pale reddish-yellow with the side and suture margined with blackish except in apical sixth; the lateral stripe occupying two intervals; the sutural stripe occupying four intervals at base, narrowed to apex.

With his usual kindness Mr. C. A. Frost sent me the subjoined Heteroptera collected by him in Nova Scotia in July 1927 and 1929, at Portaupique and Westchester. The latest data available on bugs from this part are contained in Blatchley's Heteroptera of Eastern North America; the most extensive list thus far pubished is Parshley's 1923 paper, Records of Nova Scotian Heteroptera, which appeared in Proceedings of the Acadian Entomological Society for 1922, pp. 102, 108. The present records have been checked against these; the order of the species, for convenience, is that of Blatchley's Heteroptera.
