Genus Erebia 



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, 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. H. 

 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.

 Fig. 18, $ (Sofia . 



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.
