Revision of the Genus Erelia. 191 
I found no more of it in the region where Bruce discovered 
it, and besides his original two specimens, only one other 
has, I think, been since recorded from the province of 
Assiniboia, N.W.T. 
Dr. Chapman would take this species out of the position 
in which I place it next to medusa, on account of the 
different form of the clasp, but it seems to me so near 
uralensis and polaris that 1 prefer to keep it here. 
Erebia melas. 
The difficulty which I formerly found in understanding 
the geographical distribution of this species is now re- 
moved by the fact, proved by the form of the clasps, that 
the true melas does not occur in central Europe or the 
Pyrenees. 
The only certain habitats which I know of at present 
for this species are the South-Western Carpathians, where 
it occurs abundantly in the neighbourhood of Mehadia at 
about 5,000 ft. elevation, and the mountains of Veluchi, 
in Northern Greece, where it has been taken by Dr. 
Kruper. 
I have a single specimen with a ticket “Stens? Dalm.” 
from the Vienna Museum, which seems intermediate 
between JZ. nervine and melas; it is probable that a form 
of one or other of these species exists on the mountains 
of Croatia and Dalmatia. The form which I took at 
Campiglio in the Tyrol is now proved to belong to 
glacialis, and not to melas, though at first sight it much 
more closely resembles the latter. » 
The colour of this species, when quite fresh, is black, 
and in one male taken at Mehadia by Miss Fountaine 
there is a distinct chocolate patch on the forewing below, 
sharply defined on the inside and including the three ocelli. 
A trace of this colour shows on the upper side, and in the 
female it is conspicuous on both surfaces. The ocelli of 
the hindwing, normally three in number but occasionally 
four, are sometimes wanting on the upper as well as 
the undersides. 
Erebia lefebvrer. 
This is without question a distinct species, confined 
to the Pyrenees and Asturias mountains. It has three
