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.

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 underside 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.
