Genus Brenthis 
(5) Brenthis chariclea, Schneider, Plate XV, Fig. 4, <3 
(Chariclea). 
Butterfly , 6.—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. 
$ .—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, 
6 , 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 j 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; $, 1.75 inch. 
Early Stages. —Unknown. 
This species, originally described from Labrador, is found 
throughout boreal America and British Columbia.
