southern part of British Columbia, and is found as far east as

(28) Argynnis snyderi, Skinner, Plate XVIII, Fig. 6, 3 
(Snyder’s Fritillary). 
Butterfly , 3 . —The wings on the upper side are light tawny, 
but little obscured by fuscous at the base. The black markings 
are moderately heavy and very sharply defined against the 
lighter ground-color. The outer margin is distinctly but not

the ground-color from the base to the outer belt is brownish. 
Expanse, 3 , 3.00 inches; ? , 3.30 inches. 
Early Stages. —Unknown. 
This species, which is very closely allied to A. coronis , is 
found in Utah. 
(29) Argynnis callippe, Boisduval, Plate XI, Fig. 1, 3 ; 
Fig. 2, $ ; Fig. 3, 9, under side (Callippe). 
Butterfly. —This species may easily be recognized by the 
general obscuration of the basal area of the wings, the light- 
buff quadrate spots on the discal area of the fore wings, and the 
clear oval spots of the same color on the hind wings, as well as 
by the light triangular marginal spots, all standing out distinctly 
on the darker ground. The wings on the under side are quite 
pale buff, with the spots large and well silvered. Expanse, 2.30- 
3.00 inches. 
Early Stages. —Unknown. 
Callippe is abundant in California.
