The following notes are written to place on record certain authentic records of tropical species taken in the southern United States. Most of these species are not at present recorded in the North American lists. Unless otherwise stated all specimens are in the author's collection.

In my Southern California List (Cal. Acad. Sci. 1901) a specimen of Agyrtes taken by myself at Pomona was deferred to longulus Lec., our only known species of the genus. Some years later a second example was taken at Pasadena, and more recently specimens from Washington and Vancouver have come to hand. These last agree with LeConte's type from near San Francisco, but the Southern California specimens show certain differences which seem to warrant their being set apart from longulus either as a subspecies or, as I prefer to call them, a distinct species for which I propose the above name.

In 1932, severe defoliation of alders (Alnus rubra Bong.) in Stanley Park, Vancouver, drew attention to a sawfly, Hemichroa crocea Geoff., which was responsible for the damage. More extensive infestations have occurred during the past six years on alder in the lower Fraser Valley. In Europe, the species has been known for a long time as a defoliator of various species of alder (W. Konow, Chalastogastra, 1901-1905). In 1936, R. Glendenning of Agassiz, B. C. said in a letter that he had found the larvae causing some injury to cultivated filberts.

I employ this subfamily name as used hy Hampson although I believe that in all probability it must be restricted to the genus Acronicta Ochs. and its few close allies, and the term Ampphipyrinae, as used by Seitz in his Macrolepidoptera of the World, employed in its place.

While rearranging our North American species of the genus Erebia in accordance with the recently published Monograph of the genus by B. C. S. Warren (1936) I was struck by the fact that in several instances our Canadian species had, especially as regards their areas of distribution, been treated in a rather superficial manner and with less of the thoroughness which marks the treatment of the balance of the species. This was probably due both to lack of material for study and of published distributional data; I offer therefore the following notes, based on the material in the Canadian National Collection, with a view to supplementing Warren's monumental work. The arrangement of species is that of the Monograph.

Several years ago the writer received, for determination, several specimens of a species of Coenonympha from Oregon. These specimens turned out to be Coenonympha ampelos Edwards. They were taken in August. Comparing these August specimens with a large series of specimens taken during the latter part of May and early June, I found that the two broods of ampelos were different. The summer brood was slightly lighter in color and much browner, with very little of the dark powdering found on the underside of the secondaries in the spring brood.

One does not usually associate springtails with snakes. Nevertheless a snake was indirectly responsible for the discovery of the first North American representative of the interesting and peculiar Collembolan genus Oncopodura. In 1932 Professor J. E. Guthrie received a snake from Mr. O. C. Van Hyning of Marianna, Florida, mailed alive in moss. Instead of discarding the moss, Professor Guthrie requested that its Arthropod fauna be extracted.

Herewith are described five new species of North American Plecoptera. Included also is a description of Isoperla petersoni Needham (nec Claassen). Dr. Needham published figures of the nymph and adult of this species, anticipating that I would publish a description of this species before the Utah bulletin appeared in print. In 1931 I described the nymphs of this species as my own. Under the rules of the International Code, however, I believe that this species should now stand as indicated in this paper.

In the course of revising the subfamily Cuculliinae of the Noctuidae, it has become obvious that many of the species have been placed in genera where they do not belong, and others have been merely “dumped” into the most convenient genus; it is to rectify the above conditions that the following genera are described.

The present paper is an outgrowth of a collecting trip made by myself to the eastern arctic during the summer of 1935. The month of August was spent in the vicinity of Lake Harbour, Baffin Island, and brief stops were made at Port Burwell, Que., at Craig Harbour, Ellesmere Island, and at Pangnirtung and Clyde, Baffin Island. Results were satisfactory, considering the difficulties which the collector must experience in the region, and this success was due largely to indispensable aid received from Major D. L. McKeand of the Lands, Northwest Territories and Yukon Branch, Department of the Interior, and from Mr. James Bell and Mr. Nelson Adams of the Hudson's Bay Company, Lake Harbour.

Beaverlodge, July 19, 1931. I ♀ (Strickland.) This was described in 1878 as Panurgus maurus from specimens taken in Colorado. A related species is H. campanulae Ckll., from Washington State. In 1924 (Psyche XXXI, p. 243) I described H. crassipes from Oregon, supposed to be a member of this group. I no longer have access to a specimen, but I now think it is to be called Betheliella crassipes. The genus Betheliella was based (Entom. News, XXXV, 1924. p. 169) on B. calochorti Ckll., visiting Calochortus (Mariposa lily) in California.

The material on which the following paper is based is deposited in the United States National Museum to whose authorities I am indebted for the privilege of studying the collections of spiders in their charge. Several colleagues have been very generous in lending material and in giving advice. Particular thanks are due to Miss Elizabeth B. Bryant of the Museum of Comparative Zoology, Dr. W. J. Gertsch of the American Museum of Natural History, and Professor R. V. Chamberlin of the University of Utah.

The following report deals with the description of one apparently undescribed species from Artemisia, and distributional notes on several additional aphid species belonging to the genus Capitophorus.

Cases of human myiasis have been recorded, on various occasions, from a number of widely scattered localities in Alberta. In several instances the causative larvae have been placed in alcohol and sent to this department for identification.

There has been much said, pro and con, on the species known as Euphydryas editha Bdv., and its forms, but it seems that the last word is still unspoken.

For several months I have been working on the problem presented by this group, and it seems that the race found in the San Francisco Bay region has, by oversight, never been recorded. My attention was also drawn to this fact by Dr. McDunnough of Ottawa, to whom must go the credit.

During the course of investigation of the mayfly fauna in streams in Ontario and Quebec it became apparent that many of the nymphs of the Baetinae are not known although the adults of most have been named. A few nymphs are described in scattered papers in the literature and a key has been made for some Baetis and Pseudocloeon (McDunnough 1932, 1932a) which satisfactorily separates groups within these genera. It would seem that in work on streams in the future these small mayflies would become increasingly important because of their abundance and wide distribution.

Length 6 mm.; reddish yellow; beak, antennae, ovipositor sheaths, apices of hind tibiae, and posterior tarsi, dark.

Female—Head: face long, rostriform; malar space five-sixths eye height; face in profile slightly impressed in middle; apices of antennal plates forming a low elevation. Slight groove between antennal plates. Lateral ocelli slightly further from each other than from median ocellus. Ocell-ocular line three times the diameter of a lateral ocellus. Margin of frontal impressions well developed, highest opposite middle of median ocellus, continuous to lateral ocelli. Face very sparsely punctate, shining.

The following report deals with species of Macrosiphum collected upon Chrysothamnus and Gutierrezia in Utah and nearby areas of the West.

Except for one species described by Cresson as Cteniscus californicus, but apparently referable to this genus, all the known American species occur in Canada. A study of the material contained in the National Collection has revealed several species which appear to be new. Descriptions of these are given below together with notes on the previously described species and a key is provided for the separation of all species except californicus. According to the original description of californicus it differs from the species here treated in having the mesoscutum prominently marked with two reddish longitudinal stripes.

It has long been known that the species figured by A. Gibson under the name incorrupta Hy. Edw. in his excellent paper on Canadian Apantesis species (1903, Can. Ent. XXXV, p. 145, Pl.) is not the true incorrupta, which is a synonym of geneura Stkr. (1916, B. & McD. Contrib. III (3), 158). As there is apparently no name available for our Canadian prairie species I propose the above one in honor of one of the pioneer workers in this group in Canada.
