The form of varmenio which I took in the liigh Tchuja 

 Mountains is constantly smaller than those which I found 

 in the Tchuja and Bashkaus Valleys, and from those taken 

 at Ongodai by Berezowsky, only one male out of ten pairs 

 from the liigh mountains could be confused with all the 

 other specimens I have. The males of this high level 

 variety which might be distinguished as var. alpina, 

 average about 45 mm. ; the largest (one male) is 51 mm. 

 The females measure about 40 mm. The smallest of the 

 males from Ongodai is 51 mm., and the average about 

 53 or 54 mm. This alpine form is also much darker 

 with less rufous in the fore-wing and the ocelli smaller ; 

 on the underside I see no difference. The Altai Mountains 

 appear to be the most westerly locality in which jyarmenio 

 has been taken. It is common in the Irkut Valley ; Dorries 

 found it in high-lying forests in the Kentei Mountains in 

 Mongolia, and Graeser took it abundantly at Pokrofka on 

 the Upper Amur. 



Among all the insects I collected in the Altai none 

 have given me anything like so much difficulty to identify 

 as the species of CEneis, and though I have compared 

 them very carefully with what I believe to be now an 

 unequalled series of all the known species, I am still 

 doubtful what to call some of them. Though I revised 

 the genus so recently as 1893,* and endeavoured to use 

 the form of the clasp as a guide to the separation of the 

 allied species the acquisition of much new material obliges 

 me, as I find it usually does, to modify several of the 

 opinions then formed, and as I am practically obliged to 

 revise the Asiatic species again in order to identify the 

 Altai ones, I may as well give the results here.

I found this rare and little-known species at one spot 

 only, about thirty miles south of Kuch Agatoh, on stony 

 ground among rocks, and confined to a very narrow area. 



As we rode up the valley on June 25th, and had just 

 come in sight of the first flock of Ovis amnion, I saw a 

 specimen settled on a rock and caught four males in 

 about five minutes. 



On June 28th I returned to the place, and after
