E. stubbendorfi, Mén., or what has been identified with 
this by Staudinger, is ike mawrisiuvs but with little or no 
chocolate in the cell; the band of yellowish patches on 
the forewing is therefore more defined on the underside 
and on the hindwing variable or even absent. 
L. haberhauert was taken in the Tarbagatai mountains 
which are connected with the Altai range, and differs in 
having the chocolate cell less defined and in the smaller 
and rounder spots of the hindwing below, which in one of 
my specimens are almost obsolete. 
EL. pawlowskyi from the mountains near Urga and of 
Irkutsk, has no chocolate in the cell above, and the band 
of spots on both wings much reduced. On the underside 
however the series on both wings is more conspicuous and 
much paler in colour (in the 2 almost white), but there 
is considerable variation in the size, number and colour. 
Dr. Chapman can find no characters in the clasps of any 
of these by which they can be distinguished inter se. 
In the Yellowstone Park of North America and also on 
the west coast of Hudson’s Bay has been found an Erebia, 
which Strecker described as sofia and considered almost 
the same as haberhauert, and which was afterwards named 
ethela by Edwards. I have three males and two females 
from the Yellowstone which have most resemblance to the 
male of £. haberhauert and the female of £. pawlowskyt. 
All five however have a more or less defined pale patch in 
the cell of the hindwing below, of which only a faint trace 
can be seen in two or three of my 20 Asiatic specimens, 
and by this patch I am at present able to distinguish any 
American from any Asiatic specimen I have seen. 
The nomenclature might therefore best stand as follows:

This species, though apparently belonging to the same 
group as maurisius, is very well distinguished by the pale
