and with rounder wings than the average of epijjsodea, 

 but are best marked by the entire absence of ocelli on 

 either wing or on either surface and the partial disap- 

 pearance of the red band. Though I do not attach great 

 importance to ocelli in the Erebias as a specific character, 

 yet these specimens are certainly a well-marked variety, 

 and among thirty specimens of medusa and sixteen of 

 epipsodea I have none in which the ocelli on either fore 

 or hind wing are wanting. 



E.psodea, Hiibn., which by Staudinger is treated as a 

 form of medusa, confined to South-eastern Europe, but 

 which is recorded also from Monte Baldo, in Italy, is 

 separated specifically by Von Gumppeuberg, but the 

 characters which he relies on are not visible in my 

 specimens from Eperies, in North Hungary. 



E. styg7ie.— This species, though it has not a very wide 

 range, is extremely variable, but none of its varieties 

 seem sufticiently fixed to have received names. It is 

 extremely abundant in the Pyrenees, where some of the 

 females have a pale band, almost white, on the under side 

 of the hind wings ; and both sexes have the bands 

 and ocelli wider and more conspicuous than is usual in 

 the Alps, where both are sometimes almost, if not quite, 

 obsolete. Some Pyrenean specimens come so close to 

 evias, which occurs with it, but has a rather higher range, 

 that I can hardly distinguish them except by the under 

 side of the hind wing ; and others are somewhat like 

 some specimens of nerine, which apparently represents 

 it in the Eastern Alps. 



E. evias, m Switzerland, occurs in the hot parts of the 

 Valais, at a low elevation, and flies early in the season ; 

 in the Pyrenees it ascends to 6000 or 7000 feet, and is 

 found also in the mountains of Central and Eastern Spain. 



E. melas is a species which varies extremely, and may 

 perhaps be separated into two or three forms, of which the 

 typical mclas is found in the Pyrenees, and in South-eastern 

 Europe from Carniola to the Carpathians and Greece. 



The variety lefebvrei, Boisd., with much larger ocelli, 

 and in some specimens, especially the females, with a 

 broad band on the fore wings, occurs in the Central 

 Pyrenees, and again, as hewitsoni, in Armenia, Georgia, 

 and Suanetia. This last is separated specifically by Von 

 Gumppenberg, and seems to me as near to evias as to 

 7nelas ; but strange to say, neither form is found in the
