This cockroach was found on November 2 last in a house in the City of Montreal by Mr. E. R. Bellemare. Immature individuals as well as adults were numerous.

I have recently had occasion to examine a good deal of Californian material sent me for determination by those two excellent and enthusiastic collectors, Messrs. E. C. Johnston and William Bauer. In the course of identification work some apparently undescribed species were discovered; this present paper deals with these and with a few other things that have been accumulating in our collection.

Resembles ellopiae Hgtn. in structure and sculpture, but with abdomen entirely black, not red as in that species. In Cushman's and Townes's synopses it traces to sodalis Ruthe, which it resembles in color, but from which it differs in its rounded, rather strongly receding temples, shorter malar space, narrower ocellocular space, very narrow epipleura of abdominal segments two, three, and four, the absence of median longitudinal propodeal carinae, and the much paler color of the wings.

Palpi metallic blackish, smooth scaled, second joint with very slight apico-ventral tuft. Antennae simple, black, with apical seventh white, basal segments moderately swollen.

The preceding part under this general title was published in 1941 (Can. Ent., 73:85-90). The majority of the novelties discussed herewith were collected by myself in the mountains of Colorado; for other specimens I am indebted to Professor Harry C. Severin, South Dakota State College; Dr. Charles D. Michener, University of California; and Dr. Alan Stone of the United States National Museum. Where not indicated to the contrary the types of the novelties are preserved in my extensive collection of these flies.

The gilanus group and T. sequax Will. are elements obviously divergent from T. bovinus L., genotype of Tabanus s. str., but which are provisionally retained in the genus s. lat. for reasons stated previously (Philip, 1941). The three following new species (one from northwestern Mexico) are related to the gilanus group.

The discovery of an interesting species of Petalodes in a lot of Braconidae taken in British Columbia prompted the writer to submit a specimen to Dr. C. F. W. Muesebeck of the United States National Museum, for his opinion on the species, which from the literature seemed to be quite close to the genotype, Petalodes unicolor Wesm., of Europe.

Four species of the Genus Grammotaulius, one of which is now considered a synonym, have been recognized in North America. These have been recorded only from Greenland, Canada, and northwestern United States. In August, 1940, Dr. C. E. Mickel and Mr. H. E. Milliron collected a series including both sexes of a new species in Colorado.

Two interesting mayflies, one a Lachlania and the other a Campsurus have been sent recently to the author, the former from Saskatchewan and the latter from Manitoba. Both are apparently new species and are described in this paper.

Ater several seasons of collecting, it has become evident that Gluphisia lintneri Grote and G. avimacula Hudson, which both occur at Ithaca, are not forms of the same species, as they do not fly at the same time, lintneri being on the wing about a month before avimacula, the former occurring in late April and the latter in late May, and this lapse of time between the two periods of flight of the forms does not constitute enough for the production of two broods.

Since the writer's list of the Odonata of Manitoba was published, six species have been added to the fauna of this province and the ranges of some of the species already listed have been considerably extended. Most of these new records are based on the following collections:

1. Forty-four specimens from Churchill, on the coast of Hudson Bay (58°50' N. Lat.), collected in 1936 by Mr. H. Elliott McClure and submitted for identification to the writer by Professor B. Elwood Montgomery of Purdue University, Lafayette, Indiana. All of these with the possible exception of one species were taken on July 18 and are labelled “Bush.”

After Barnes and Benjamin transferred pulverulenta Smith to Pseudanarta Grote (Pan-Pacific Entomologist, III, 110-111, 1927), it was thought that the matter ended there, as the species had obviously been referred to the correct genus. However, in the course of working over the Cuculliinae, a number of slides of the genitalia of this “species” were made, and these exhibited constant differences, which made me believe that we were dealing with a group of species and not one.

Following are comments, descriptions, or new information on species of Nearctic Tabanidae, anticipating compilation of a catalog of the family for the region. Also included is a description of a new species from Mexico which may be taken ultimately in the extreme southwestern United States.

In a collection of Mycetophilidae taken by H. E. McClure in Manitoba during the summer of 1936, there are two new species of the genus Sciara. The following are the descriptions of these new species.
