♀.--The female is paler than the male. On the upper side of the hind wings the second row of silver spots is indicated by spots much paler than the ground. The black markings are lighter than in the male. Expanse, ♂, 2.00 inches; ♀, 2.20 inches.
This species, which is somewhat like _A. coronis_, but smaller, and brighter fulvous, is found in California, but is still quite rare in collections.

_Butterfly_, ♂.--The wings are bright fulvous on the upper side, with the black markings much as in _A. adiante_, slight on the fore wings and even slighter on the hind wings. The under side of the fore wings is cinnamon-red at the base and on the inner half of the wing, beyond this buff. The apical patch and the outer margin are brown. The upper marginal spots and two spots on the subapical patch are well silvered. The hind wings are rusty-brown from the base to the second row of spots, mottled with lighter brown. The marginal belt is clear brownish-buff. All the spots are well silvered.
♀.--The female on the upper side is colored like the male, with the dark markings somewhat heavier. On the under side the fore wings are laved over almost their entire surface with red, the upper angle of the cell alone being buff. The hind wings are in many specimens fawn-colored throughout, except that the marginal band is paler. In a few specimens the ground is darker and the band more distinct. All the spots are well silvered. Expanse, ♂, 2.60 inches; ♀, 2.75-3.00 inches.
_Early Stages._--The life-history of this butterfly has not been ascertained.
The species appears to be very common at San Bernardino, California, and vicinity, and resembles _A. adiante_ on the upper side and _A. coronis_ upon the lower side.
