(3) =OEneis macouni=, Edwards, Plate XXVII, Fig. 3, ♂ (Macoun's Arctic). [Illustration FIG. 123.--Caterpillars of _OEneis macouni_ (Riley).] _Butterfly._--This species is closely allied to the two foregoing, but may be distinguished by the broad median band of dark brown traversing the under side of the hind wings, as well as by other peculiarities of marking. It lacks the bar of raised scales which is found in the male sex about the lower part of the cell of the fore wing in most of the species of the genus. It has been found thus far only on the north shore of Lake Superior and at the eastern base of the Rocky Mountains in the territory of Alberta. Expanse, 2.00-2.25 inches. _Early Stages._--For a knowledge of these in all their minute details the reader is again referred to the pages of the indefatigable Edwards. (4) =OEneis chryxus=, Westwood, Plate XXVII, Fig. 10, ♂ (The Chryxus Butterfly). _Butterfly._--This species is widely distributed, being found in Colorado, British Columbia, and the vicinity of Hudson Bay. It is distinguished from other species by the darker brown color, which covers the basal and median areas of both the fore and hind wings, leaving a broad band of lighter brown on the outer margin. On the under side the wings are beautifully mottled with white and dark brown. _OEneis calais_, Scudder, is probably only a form of _chryxus_, which is somewhat lighter in color on the base of the wings. Expanse, 1.60-1.75 inch. _Early Stages._--The life-history is fully recorded in the pages of Edwards.
