(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.
This striking species has been heretofore only found in British Columbia.
(23) =Argynnis behrensi=, Edwards, Plate XIV, Fig. 10, ♂, _under side,_ (Behrens' Fritillary).
_Butterfly._--The male on the upper side is dull fulvous, clouded with fuscous at the base, the black markings much narrower and lighter than in the preceding species. The primaries on the under side are pale fulvous, clouded with dark brown at the apex. The subapical spots and the upper spots of the marginal series on this wing are well silvered. The hind wings on the under side are deep reddish-brown, with the marginal band only faintly indicated. All the spots are distinctly well silvered. The female does not differ materially from the male, except in the larger size and the somewhat paler ground-color of the upper side of the wings. On the under side the wings are exactly as in the male, with the marginal band even less distinct than in that sex.
The type specimens upon which the foregoing description is founded came from Mendocino, in California.
