_Butterfly._--This species is very closely allied to the preceding in some respects; the upper surface, however, of the wings in both sexes is brighter than in _zerene_, and the dark markings stand forth more clearly upon the lighter ground-color. The wings are not shaded with fuscous toward the base as much as in _A. zerene._ While the markings on the upper side are almost identical with those of Dr. Boisduval's species, they are much brighter and clearer, giving the insects quite a different aspect. On the under side the wings are colored as in _zerene_, the primaries in the male being ferruginous, laved with a little red toward the base, marked with purplish-gray toward the apex, the light spots near the end of the cell on this wing being pale buff. The hind wings are very uniformly purplish-gray, mottled with dark brown, the spots very little, if at all, silvered in the male. In the female the fore wings are bright red at the base, and the hind wings are colored as in the male; but all the spots in both the fore wings and hind wings are broadly and brightly silvered. _Early Stages._--The early stages have not been ascertained, and there remains something here for young entomologists to accomplish. This species is quite common in the same localities as the last, and some authors are inclined to regard it as being a mere variety, which is a belief that can only be verified by careful breeding from the egg. (22) =Argynnis rhodope=, Edwards, Plate XI, Fig. 6, ♀, _under side_ (Rhodope). _Butterfly._--In the male sex the upper side is bright fulvous, with both wings on the inner half heavily clouded with dark fuscous. The black markings are very heavy and confluent. The outer border is solid black, very slightly, if at all, interrupted by a narrow marginal brown line, in this respect resembling _A. atlantis._ On the under side the fore wings are dark ferruginous, on the outer margin rich dark brown. Between the spots at the end of the cell and the nervules below the apex are some clear, bright straw-yellow spots. The upper spots of the marginal series are silvered. The hind wings are dark reddish-brown, very slightly paler on the line of the marginal band. The spots are pale straw-yellow, except those of the marginal series, which are distinctly silvered. The female on the upper side is of a lighter and brighter red, with the markings dark and heavy as in the male sex. On the under side the markings in the female do not differ from those in the male, except that the primaries on the inner half and at the base are bright pinkish-red. Expanse, ♂, 2.20 inches; ♀, 2.40 inches. _Early Stages._--Unknown. This striking species has been heretofore only found in British Columbia.
