Walsingham described this species from a variable series of specimens taken in Colusa, Shasta and Siskiyou Cos., Calif. No definite type is designated but from correspondence with Mr. W. H. T. Tams of the ,British Museum I find that the author marked his types "Type I" and "Type II." Type I, the obvious holotype, is labelled "Pit River, Shasta Co. California, VII, 1871, P1. 2, fig. 13" and according to Mr. Tams is much the tawnier of the two "types." Type II is labelled "Uncle Sam Mount, Lake Co. Calif. VI, 1871, PI. 2, fig. 14" and, as the figure shows, is a pale, immaculate form. Barnes and Lindsey make californica Grin. (1908, Can. Ent. XL,, 321) from S. Calif. a synonym and describe the color of the forewings as creamy-white to tawny-brown, the latter color being that given by Grinnell in his description of californica.
