Butterfly.--The male on the upper side is marked much as A. nokomis, but the ground-color is duller red, and the basal area is much darker. The under side of the fore wings is pale fulvous, upon which the markings of the upper side reappear; but there are no marginal silver crescents. Both wings on the under side are shaded with brown toward the base; the hind wings are traversed by a submarginal band of light straw-yellow. The female is marked as the male, but the ground-color is pale straw-yellow, and all the darker markings are deep blackish-brown, those at the base of both wings being broad and running into one another, so that the inner half of the wings appears to be broadly brownish-black. On the under side this sex is marked as the male, but with the dark portions blacker and the lighter portions pale yellow. Expanse, 2.50-3.25 inches.

The life-history of this insect remains to be worked out. It is one of our most beautiful species, and occurs in California and Oregon.
