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

(28) Argynnis snyderi, Skinner, Plate XVIII, Fig. 6, $ 

 (Snyder's Fritillary). 



Butterfly, $ . 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 r 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, $ , 3.00 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. I, S ; 

 Fig. 2, $ ; Fig. 3, ? , under side (Callippe).

 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. 



(30) Argynnis nevadensis, Edwards, Plate X, Fig. 4, $, 

 under side (The Nevada Fritillary). 



Butterfly, $ . The ground-color is pale fulvous, but little ob- 

 scured with fuscous at the base. The outer margins are heavily 

 bordered with black. The dark markings of the discal area are 

 not heavy. The fore wings on the under side are pale buff, the
