Three species of flies are here described as new. The material was collected in Utah, Idaho, and Colorado, with one specimen from South Dakota.

Argyra condomina n. sp.

Male. Length, 3.8 mm.; length of wing, 3.5 mm. Face silvery pollinose, short. leaving the lower corners of eyes sharply exposed, considerably narrowed on lower portion. Front and occiput heavily dusted with gray pollen.

The preceding part under this title was published in 1945 (Can. Ent. 77: 1-6). In the present article I am describing various novelties from the western United States and Canada, received from different entomologists who are listed under the individual species and to whom my sincere thanks are extended. Except where indicated to the contrary, the types of the various novelties are preserved in my personal collection of these flies.

A number of our species of North American Coleophoridae are characterized by their unicolorous dark gray-brown forewings and lack of a prominent basal tuft on the antennae, making an identification of the individual species a rather difficult matter unless recourse be had to genitalic characters which in both sexes offer excellent means of separation.

The pale western cutworm, Agrotis orthogonia Morr, has been a serious pest in the semi-arid prairies of Western Canada since 1911. Only recently, however, has an effective control been developed which can be used in the spring of the year of outbreak. Seamans (1938), after many years of field observations, published a non-technical bulletin dealing with a method of control by starving the small cutworms early in the spring.
