Erebia Sofia

Plate XXV — Erebia Sofia is Fig. 18
Plate XXV — Erebia Sofia is Fig. 18

Butterfly.--Dark brown on the upper side, with an even submarginal band of red spots on the primaries, and five similar spots on the secondaries, the last two of the latter somewhat distant from each other and from the first three, which are nearer the outer angle. On the under side the primaries are reddish, with the submarginal band as on the upper side, but paler. On the secondaries, which are a little paler below than above, the spots of the upper side are repeated, but they are yellowish-white, standing forth conspicuously upon the darker ground-color.

Early Stages.--Hitherto undescribed.

Sofia has been found at Fort Churchill in British America, in the Yellowstone National Park, and in a few localities in Colorado. It is still rare in collections. The figure in the plate is that of the female type of Edwards' ethela, ethela being a synonym for sofia.
