Revision of the Genus Erebia. 203 
In the Hudson Bay specimens these ocelli are four or 
five in number, in Bremer’s plate four, and in the Siberian 
specimens I have seen two or three. 
There is a more or less distinct dark band followed by 
an outer paler one on the hindwing below, which is more 
visible in the American than in the Siberian specimens, and 
is hardly shown in Bremer’s figure ; but this is nothing like 
so distinct or well marked as in the true /fasciata, which 
has a most distinct broad band below not only on the 
hindwing but right across the forewing and reaching the 
costa. 
Erebia cyclopius. 
A very distinct species in my opinion, though Dr. Chap- 
man considers it a near ally of embla-disa. It extends 
from the Ural Mountains and eastern Altai to Amurland 
and the island of Askold, and appears to vary but little. 
The supposed variety of it described by Trybom from the 
Yenesei river as “var. intermedia,” turns out from an 
examination of a specimen lent by Prof, Aurivillius to be 
L. edda, a very different species. 
Hrebia fasciata. 
This, so far as I know, has never been taken except at 
Winter Cove in Cambridge Bay, Victoria Land, about 
69° N., 107° W., by Capt. Collinson’s expedition, and by 
Sir John Richardson’s expedition on the Arctic coast in 
67-68° N. 
These specimens are all in the British Museum except 
one pair which I received in exchange from this source. 
Erebia magdalena. 
This species, which I knew before only from specimens 
taken by Mr. Bruce, is at present only recorded from the 
mountains of Central Colorado. I was fortunate enough, 
when visiting this country in July, 1893, to see and take 
it myself. It frequents just such steep stony slopes as 
E. glacialis prefers in the Alps, and it seemed fairly com- 
mon at from about 11,800 to 12,800 feet. During the 
first week in July I found it easier to catch and not so
