Under this general title, I plan publish from time to time taxonomic and biologic notes on several groups of Coleoptera in which I am particularly interested. This paper discusses the characters and habits of four species and adds some general observations on the family Silphidae.

This giant race of the species freija Thun. was collected along the Alaska Military Highway in British Columbia. In size and wing shape this would appear to be a race of frigga Thun. rather than of freija, and we have no doubt but that those who depend on external characters only will insist that we are in error; nevertheless gentalic study leaves no doubt as to its true relationship with freija.

All stages of the spruce budworm parasite Glypta fumiferanae (Viereck) are described in this paper. Illustrations of all stages are presented.

Since the appearance of Dr. Braun's article and my own paper dealing with the species of this complicated group of Aster- and Solidago-feeders in which the forewing maculation is more or less similar, I have paid particular attention in field work, especially in the Maritime Provinces, to securing long series of specimens and, whenever possible, males and females in coitu. In consequence I have had before me for study several hundred specimens and have made large numbers of genitalic slides of both sexes with the especial idea of trying to discover adequate characters in these organs whereby the females of the individual species may be separated.
