it, and was much surprised to find, so far from the locality 

 where it had previously been taken, this rare and peculiar 

 species. In two or three days it became quite common, 

 and throughout the month of July, wherever the ground 

 was suitable, it was with Aryynnis frcija, one of" the most 

 abundant butterflies. It frequents steep shaly and rocky 

 hillsides from about 7UU0 — 9U00 feet, and is not difficult 

 to catch on a hot day, though of all the Ercbias I have ever 

 taken it is the most difficult to get in perfect condition. 

 I have figured two males and a female, of which figure 1 

 is the most typical. The colour of the rings round the 

 ocelli comes out too yellow in all these figures, it is 

 rather a chocolate colour. There is considerable variation 

 in the ocelli, which above are normally as follows : 

 one with a double pupil near the apex of the fore-wing, 

 and about three on the liind-wing; sometimes, however, 

 specimens such as figure 3 occur, and I have seen one in 

 the St. Petersburg Museum from Kansk, in which the ocelli 

 are even better marked than this. I have never, however, 

 seen a male in which the fulvous shows on the upperside of 

 the fore-wing as in figure 2. The hind-wing below is the 

 characteristic feature of this species, the ocelli being always 

 replaced by white dots, normally four in number, near the 

 outer margin of the paler band. The underside of the 

 fore-wing is, except the margin and costa, constantly 

 fulvous, more so than in specimens from the East Sayansk 

 Mountains, and as far as I can judge the insect, which I 

 have compared with Bremer's type, is absolutely identical 

 with those from Hudson's Bay referred to in my last 

 Revision of EreUa (Trans. Ent. Soc. Lond., 1898, p. 202). 

 If, as I believe, these are identical with rossii* which, 

 however, appears to be a smaller and Arctic form of the 

 species, the Asiatic form will have to be treated as a 

 variety of it. The fringes of all my specimens are 

 uniformly dark, but in one or two there is a slight 

 tendency to pale chequering, which is better marked 

 in a female from Chamardaban, ex. coll. Grum-Grshimailo.

This is another of the rare species hitherto only known 

 from Eastern Siberia. I found it first in the Tcliuja 



* The genitaliu seem to be identical with tho?e of rossii as figured 

 by Aurivillius, Ins. Vega Exp., iv, t. 1, iv. Cy. Elwes, Trans. Ent, 

 Soc, 1898, p. 202.
