Genus Brenthis 



(5) Brenthis chariclea, Schneider, Plate XV, Fig. 4, $ 

 (Chariclea). 



Butterfly, $ . — Fulvous on the upper side, with heavy black 

 markings, both wings greatly obscured at the base by fuscous. 

 On the under side the fore wings are pale yellowish-fulvous, 

 mottled with ferruginous at the tip and on the outer margin. 

 The hind wings on the under side are dark purplish-ferruginous, 

 mottled with yellow, crossed by a central row of conspicuous 

 yellow spots. The row of marginal spots and two or three small 

 spots at the base are white, slightly silvered. 



9 . — The female differs from the male in having the markings 

 of the upper side darker and heavier, and the outer margins more 

 heavily marked with black, and having all the spots on the under 

 side more distinctly defined against the dark ground. Expanse, 

 & , 1.50 inch; $,1.75 inch. 



Early Stages. — Undescribed. 



This species, like B. freija, is circumpolar, being found in Lap- 

 land, Greenland, and throughout arctic America. It also occurs 

 within the limits of the United States, in the Yellowstone Park at 

 considerable elevations, and is not uncommon on the high moun- 

 tains in British Columbia, numerous specimens having been cap- 

 tured in recent years about Banff and Laggan, in Alberta. 



(6) Brenthis boisduvali, Duponchel, Plate XV, Fig. 5, $ ; 

 Fig. 6, ?, under side (Boisduval's Fritillary). 



Butterfly. — Somewhat closely resembling B. chariclea, but 

 with the markings much heavier on the outer margin, and the 

 base of the wings generally more deeply obscured with dark 

 brown. The wings on the under side in color and marking 

 closely approximate those of B. chariclea, and I have been unable 

 to distinguish the specimens marked as boisduvali, and contained 

 in the Edwards collection, from the specimens designated as B. 

 chariclea in the same collection, so far as the color and macula- 

 tion of the under sides of these specimens are concerned. Ex- 

 panse, $ , 1.50 inch; 9, 1.75 inch. 



Early Stages. — Unknown. 



This species, originally described from Labrador, is found 

 throughout boreal America and British Columbia.
