Genus Argynnis 



that the dark markings on the upper side are all much heavier, 

 standing out very distinctly upon the paler ground, and the mar- 

 ginal spots within the lunules are very light in color and relatively 

 large. On the under side the fore wings are laved with red, very 

 much as in the female of A. adiante. Expanse, $, 1.75-2.00 

 inches ; ?, 2.00-2. 15 inches. 



Early Stages. — These still remain to be ascertained. 



This interesting butterfly, which seems to indicate a transition 

 between the butterflies of the Adiante-group and those of the 

 Eurynome-group, has been found in Colorado, Nevada, Utah, and 

 Arizona. 



(42) Argynnis clio, Edwards, Plate XIV, Fig. 5, $ ; Fig. 6, $ ; 

 Fig. 7, S , under side (Clio). 



Butterfly. — Closely resembling A. eurynome and A. artonis. 

 Like artonis, the spots on the under side of the wing are without 

 silver. The female very closely resembles the female of artonis, 

 and in fact I am unable to distinguish the types of the females of 

 the two species by any marks which seem to be satisfactory. 

 Expanse, $, 1.75 inch; $, 1. 75-1. 90 inch. 



Early Stages. — Unknown. 



This species, which is as yet comparatively rare in collections, 

 is found in Montana and the province of Alberta, in British Amer- 

 ica, at a considerable elevation. 



(43) Argynnis opis, Plate XIV, Fig. 8, $, under side (Opis). 

 Butterfly. — This species, which apparently belongs to the 



Eurynome-group, appears by the location of its markings to be 

 closely related to eurynome, but on the upper side the wings of 

 both the male and female are more heavily obscured with fuscous 

 at the base; the dark markings are heavier than in eurynome, and 

 in both sexes it is smaller in size, being the smallest of all the 

 species of the genus thus far found in North America. The spots 

 on the under side of the wings are none of them silvered. Ex- 

 panse, $, 1.50 inch; ?, 1.60 inch. 



Early Stages. — Nothing is known of these. 



The types came from Bald Mountain, in the Caribou mining 

 district of British Columbia.

 (Bischoff s Fritillary). 



Butterfly, $ . — The fore wings on the upper side are bright red- 

 dish-fulvous, the base of the primaries and the inner half of the
