Walsingham described the species from 1 male, 2 females, from Shasta Co., Calif. Heinrich, in his revision, confines the distribution to the eastern section of the continent and in his key to the species (p. 132) characterizes it as having “basal patch heavily shaded with black, the blackish scaling extending diagonally to middle of costa.” Neither the original description nor the figure bears out this characterization; the figure, while somewhat crude, notable in the too great prominence given the outer patches as compared with the basal one, certainly shows no connecting band between the basal patch and the midcostal one; further the description distinctly calls for a dark spot at end of cell, in fact the name is based on this feature.
