 and Amur Valley. 



(U. medusa, Fab.) 



This is the only species of Erebia which I expected to 

 find, but did not, in the Altai. Though it has not hitherto 

 been taken there, so far as I know, yet as Jacobson found 

 it in the Yenesei Valley, and Leder took it in Mongolia, it 

 will probably be found, A fine series of the variety 

 uralensis taken at Miask by Grum-Grshiraailo at the end 

 of May are fairly constant in the distinguishing characters 

 of the underside. Most of the males and all the females 

 show a well-marked grey dusting on the hind-wing and 

 apex of the fore-wing, which is characteristic of this variety, 

 and an equally fine series of medusa from Podolia, which is 

 the nearest point in Europe from which I have it, show a 

 slight trace of this in one or two females only. An 

 additional character of uralensis, which is also common to 

 var. polaris, is the absence of the large chocolate-ringed 

 ocelli on the hind-wing below.

This I took only on June 20th, close to the place where 

 edda was common, but within the forest. I found four 

 males in all, and never saw the species again, neither was 

 it found at Ongodai. These four males are precisely 

 similar to those taken in Kamtschatka by Herz, and 

 described by Alph^raky as var. suceidenta, which, like those 

 from Mongolia named laina by Staudinger, are in my 

 opinion an oriental variety, I have, however, one or two 

 males from Scandinavia hardly distinguishable from them. 

 They are fairly distinct from those which Mentitries called 

 emhla-disa, of which I have several pairs from the Vitim 

 and Vilui rivers taken by Herz, who says (Iris, xi, p. 246) 

 that many of them approach disa. When I wrote last year 

 on Erchia I said that I had seen no true disa from Siberia ; 

 there are, however, several in the Museum at St. Petersburg 

 taken by Czekanowsky on the Upper Tunguska river, 

 which cannot be separated from disa, and as I have 

 also one from Northern Siberia, we must conclude that 

 the two species remain distinguishable in Asia as in 

 Northern Europe. I may add, that among Czekanowsky's 

 Siberian collection are two or three specimens which 

 appeared to me indistinguishable from E.fasciata, Butl,,
