_Butterfly._--The male is bright reddish-fulvous on the upper side, slightly obscured by fuscous at the base. The discal band of spots common to both wings is broken and irregular, and the spots on the hind wings are quite small. The fore wings on the under side are buff at the tips and pale red at the base and on the inner margin, lighter at the inner angle. The under side of the hind wings as far as the outer margin of the discal row of silvery spots is dark brown, mottling a yellowish ground. The submarginal band of the hind wings is pale yellow and moderately broad. The female is marked much as the male, but the discal band of spots on the upper side of the fore wings is confluent and broader, the fringes whitish, and the spots included between the sagittate marginal spots and the marginal lines paler than in the male sex. Expanse, 2.00-2.20 inches. _Caterpillar, etc._--The early stages are unknown. This species is found in the territories of Alberta and Assiniboia, and in British Columbia among the foot-hills and the lower slopes of the mountain-ranges. (13) =Argynnis oweni=, Edwards, Plate XII, Fig. 5, ♂; Fig. 6, ♀, _under side_ (Owen's Silver-spot). _Butterfly_, ♂.--The wings on the upper side are dull reddish-fulvous, not much obscured with brown on the base, the black markings moderately heavy, the two marginal lines tending to flow together. The fore wings on the under side are yellowish-buff from the base to the outer row of spots, or in some specimens with the buff lightly laved with reddish; the nerves reddish-brown. The subapical patch is dark brown, with a small silvered spot; the five submarginal spots are small and obscurely silvered. The hind wings are dark brown on the discal area and outer margin, with a rather narrow grayish-buff submarginal band, strongly invaded by projections of the dark brown of the discal area. The spots of the outer discal row are generally well silvered; the inner spots less so in most cases. ♀.--The female has the wings more or less mottled with yellowish outside of the mesial band. The black markings are very heavy in this sex. On the under side the spots are well silvered. The dark markings on the upper side of the wings of the male are much heavier than in _A. behrensi_. On the under side of the wings in both sexes it may be distinguished from _behrensi_ by the fact that the ground-color toward the base is mottled with yellow, and not solid brown as in _behrensi_. Expanse, 2.25-2.40 inches. This species abounds on Mount Shasta, in California, at an elevation of seven to eight thousand feet above sea-level. (14) =Argynnis cornelia=, Edwards.
