Chariclea
Butterfly, male.--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.
Female.--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, male, 1.50 inch; female, 1.75 inch.
Early Stages.--Undescribed.
This species, like B. freija, is circumpolar, being found in Lapland, 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 mountains in British Columbia, numerous specimens having been captured in recent years about Banff and Laggan, in Alberta.
