Genus Erebia 
two black ocelli, pupiled with Wmte. 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, irreg¬ 
ular, 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.

Alpine). 
Butterfly .—The wings are dark brown on the upper side, with 
four or five black ocelli, pupiled with white and broadly sur¬ 
rounded 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 Ed¬ 
wards in ‘‘ The Butterflies of North America,” vol. iii, and by H. El. 
Lyman in the “Canadian Entomologist,” vol. xxviii, p. 274. 
The caterpillar feeds on grasses. 
The species ranges from New Mexico (at high elevations) 
northward to Alaska. It is common on the mountains of 
British Columbia.

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.
