Plate XXVII — Bruce's Arctic is Fig. 7

Butterfly.-Though somewhat closely related to the last species, Bruce's Arctic may at once be distinguished from it by the broad dark band on the under side of the secondaries and the great translucency of the wings, which permits a label to be read through them. It is found in Colorado and in British Columbia at an elevation of from twelve to thirteen thousand feet above sea-level. Expanse, 1.75 inch.

Early Stages.-All we know of these is contained in the pages of Edwards' great work.
