There commonly occur in the bark of decadent elms certain species of coleopterous larvae which are often difficult to distinguish unless they can be positively associated with their maternal egg gallery. In handling large numbers of these larvae for precise experimental purposes and in field work, satisfactory criteria for exact identification consisting of definite external morphological characters, capable of rapid use, are necessary.

The forest entomologist is often called upon to inspect insect defolialion late in the season at a time when the feeding stage of the defoliator is no longer present in the trees.

In a small collection of Coleoptera received for identification from Borys Malkin, the following new species was found.

Phymatodes malkini n. sp.

Piceous, except antennae, legs in part, base of thorax, mesosternum, metasternum, and triangular basal area of elytra, which are yellowish brown.

This list is based on one compiled by Dr. H. J. Brodie of Winnipeg and published in the Transactions of the Royal Canadian Institute, vol. XVII, part 1, 1929. Since that time the completion of the Hudson Bay Railway to Churchill has opened up territory, which previously had been but slightly worked and has made easily accessible country where the flora and fauna are subarctic. Also a number of new species, subspecies, races, and aberrations have been described from the Province, which seems to make a revised check list advisable. The old list contained 121 names, and that total has now been broucht to about 170.

Although larvae of the five species described below are among those loopers most frequently encountered in numbers, complete data on their life histories are still lacking. The following notes, based on large samples of larvae collected and bred in New England during the past three years, are intended to supplement the accounts of earlier authors and are not in themselves complete.

Since the publication of my paper dealing with the Coleophoridae of the Maritime province (1940, Trans. Roy. Soc. Can. Sec. V, pp. 53-68) I have continued my studies in the group during field work in these provinces in 1940 and 1941.

During the past five years several thousand samples of lepidopterous larvae have been collected from spruce in the course of the Canadian Forest Insect Survey (1). It was found that a considerable proportion of the species had been hitherto unknown in the larval stage, and that many others had been only briefly or superficially described. In this paper, and in subsequent instalments, descriptions will be presented for those species whose larvae, to the author's knowledge, have never been described before.

The genera here under consideration are largely western and southwestern in distribution. Little or nothing is known concerning their biology or host relationships. Characters common to both genera include the following among others: eyes bare; parafacials setose to bristled; facial ridges practically bare; epistoma narrow and somewhat elongated; arista short plumose; propleura bare; prosternum setose; apical cell closed with long petiole reaching costa far before wing tip; costal spine large; sides of postnotum beneath calypters haired.

Among the dragonflies of a fine collection made by Mrs. Dietrich in Mississippi and recently presented to Cornell University, there are two new species of Gomphus that she has modestly asked me to describe.

In 1925 Cushman (Jl. Wash. Acad. Sci., XV, 392) transferred Meniscus mirabilis Cress. to the genus Asphragis, and synonymized with it Asphragis pulcherrimus Ashm., Clistopyga pleuralis Ashm. and Meniscus ostentator Davis. Up to the present this species has constituted the only representative of the genus reported from the United States and Canada.

From time to time during the past, the writer has endeavored to collect cicadas in Alberta, his boyhood home, whenever the opportunity presented. Some of the specimens reported here were taken many years ago when the writer was still a boy; others were taken at a more recent date. The following note is written to bring up-to-date infnrmation concerning the cicada fauna of Alberta.

The preceding part under this general title was published in 1941 (Can. Ent., 73: 206-213). In the present instalment, I am discussing species included in extensive series of these flies taken by Mr. H. Elliott McClure at Fort Churchill, Manitoba; by Dr. Mont A. Cazier in California and Nevada; by Mr. and Mrs. John L. Sperry in Montana, Wyoming and New Mexico; by Dr. and Mrs. Henry K. Townes in Washington; and by Mr. John W. Zukel in Idaho.

Close to timberline in the northern part of the Olympic Mountains, particularly in the Gray Wolf Range of these mountains in the State of Washington, a small race of Plebeius lupini Bdv. occurs that is quite distinct in character. The Olympic Mountains, adjacent to the sea and snow-capped throughout the entire year, present quite a different environment to that which exists in the habitat of many insects.

Penultimate Instar. Head width 1.0 to 1.3 mm. Body length 7 to 10 mm. Otherwise similar to ultimate instar.

Ultimate Instar. Head width 1.3 to 1.5 mm. Body from 9 to 11 mm. long and from 1.5 to 1.7 mm. wide; shape subcylindrical, broadest at first abdominal segment, eighth abdominal segment with a dorsal swelling; skin densely covered with minute conical granules; ground colour pale yellow, cream-coloured, or greyish-white, heavily mottled with dark brown, dark grey, or ruddy-brown, often with a pink suffusion, venter lightly tinged with reddish-brown or even green.

The type specimens of the two species of Rhysodesmus described below were collected by Mr. Phil Rau, through whose courtesy the author received them for study. The specimens are at present in the author's collection.

During the year 1940 the following interesting additions were made to the entomological collections of the Plant Protection Service of the Quebec Department of Agriculture. All the localities mentioned are in the Province of Quebec.

During the past two summers, we have captured and reared a species of Pseudexentera Heinr. which was breeding in large numbers on the wild apple trees of the Ottawa district. It was also commonly noticed flying around the hawthorn (Crataegus sp.) of this area, and while it was not reared from this plant it is probable that Crataegus is another food-plant.
