Dr. Willis J. Gertsch has called my attention to three undescribed races of North American Lycaenidae contained in his collection of Rhopalocera which was made when he resided in Salt Lake City, Utah and has kindly supplied me with many of the specimens making up the type series.

In 1934, Knowlton and Rowe (2) recorded five species of Simuliidae from Utah, including Simulium (Simulium) vittatum Zett., and four species described as new: namely, S. (S.) brevicercum, S. (S.) nigresceum, S. (Eusimulium) pilosum, and S. (E.) utahense. In May and October, 1937, G. F. Knowlton kindly forwarded to me for examination about seven hundred specimens of blackflies collected in various parts of Utah and Idaho. A study of this material showed that nine described species and six species new to science were represented. The distribution records and descriptions of the new species are given in the following pages.

In the course of determination work, largely for Dr. J. Comstock of the Los Angeles Museum, I have received several species of Lepidoptera which appear to be undescribed. I therefore offer descriptions of these in the present paper. Through the courtesy of Dr. Comstock and Mr. Don Meadows the types are deposited in the Canadian National Collection.

A medium sized, polished black species, closely resembling picipes Aubé in general facies. Under side polished metallic black; legs dark, especially the middle and hind pairs.

While collecting in the Cape Breton region of Nova Scotia early in July 1936, Dr. J. McDunnough and the writer collected a series of more than one hundred specimens of a P. scudderi form, commonly flying in a sphagnum bog about one and one half miles north of Baddeck on Highway No. 5, and which we thought might possibly be the race aster, described by Edwards from the Cape Race region in southern Newfoundland.

A new record for the distribution and environment of Grylloblatta campodeiformis Walker has been established by the recent discovery of this insect in the dry belt of British Columbia at an altitude of 1500 feet. The occurrence of the “ice bug” at this locality is of singular interest. Supposedly an inhabitant of only the coldest regions, such as are found along the margins of glaciers and mountain streams at high altitudes, this discovery shows that Grylloblatta can exist under extremely dry and hot conditions at a relatively low altitude.
