The type female differs from the parat3T)e females in having the an- tenna almost entirely black, with only a tinge of fulvous on scape and first three segments of flagellum, and no white band on flagellum. The fourth segment of the flagellum is as long as wide. In the para type females it is about as long as wide, T}T)e: 9, Vernon, Utah, May 1, 1936, G. F. Ivnowlton and C. F.
