Butterfly.—The wings are dark brown on the upper side. On the outer third below the apex are three or four black ocelli, broadly ringed with red and pupiled with white. The upper ocellus is generally bipupiled, that is to say, the black spot is twinned, and there are two small light spots in it. On the under side the fore wings are as on the upper side. The hind wings are broadly sown with gray scales, giving them a hoary appearance. The base is more or less gray, and there is a broad, regularly curved mesial band of dark gray, which in some specimens is very distinct, in others more or less obsolete. The female does not differ from the male, except that the ocelli on the fore wings are larger and more conspicuous.
Early Stages.—Unknown.
This species is found in Alaska and on the mountains of British Columbia.
(3) Erebia callias, Edwards, Plate XXV, Fig. 20, ♂ (The Colorado Alpine).
Butterfly.—Pale brown on the upper side, with a more or less indistinctly defined broad transverse band of reddish on the outer third of the fore wings. At the apical end of this band are two black ocelli, pupiled with white. The fore wings on the under side are reddish, with the costa and outer margin grayish. The ocelli on this side are as on the upper side. The hind wings are gray, dusted with brown scales and crossed by narrow, irregular, dark-brown subbasal, median, and submarginal lines.
Early Stages.—Unknown.
This species is not uncommon on the high mountains of Colorado and New Mexico. It is regarded as a variety of the European E. tyndarus, Esper, by many. All the specimens of tyndarus in my collection, and there are many, lack the ocelli on the fore wing, or they are very feebly indicated on the under side. Otherwise the two forms agree pretty closely.
(4) Erebia epipsodea, Plate XXV, Fig. 28, ♂ (The Common Alpine).
Butterfly.—The wings are dark brown on the upper side, with four or five black ocelli, pupiled with white and broadly surrounded by red near the outer margin of the fore wings, and with three or four similar ocelli located on the upper side of the hind wings. The spots on the upper side reappear on the under side, and in addition the hind wings are covered by a broad curved median blackish band.
Early Stages.—These have been carefully described by Edwards in "The Butterflies of North America," vol. iii, and by H.H. Lyman in the "Canadian Entomologist," vol. xxviii, p. 274. The caterpillar feeds on grasses.
