(34) =Argynnis rupestris=, Behr, Plate XII, Fig. 8, ♂. Fig. 9, ♂, _under side_ (The Cliff-dwelling Fritillary).
_Butterfly_, ♂.--The upper side of the fore wings is deep reddish-fulvous, with the black markings very heavy. The fore wings on the under side are buff, shaded with red at the base and on the inner margin. The spots are buff, without any silver. The hind wings are buff, mottled with cinnamon-red, sometimes dark, sometimes lighter. The marginal belt is narrow, buff, encroached upon by the darker color of the median area at the ends of the oval spots. None of the spots is silvered, except very lightly in exceptional cases.
♀.--The female is much like the male on the upper side, with the dark markings much heavier, the ground-color somewhat paler, and the marginal row of spots quite light. The wings on the under side are more brightly tinted than in the male, and the marginal spots are more or less silvered. Expanse, ♂, 2.00 inches; ♀, 2.20 inches.
_Early Stages._--Nothing is as yet known about the egg and larva.
