Lepidoptera of the Altai Motmtains. 367 



177. P. argyrostigma, Ev. 



I was very much pleased to find this interesting species, 

 which has not previously been recorded from Western 

 Siberia, common at Ongodai on June 13th, when the 

 males were abundant, but I only got a single female. 1 

 found it in the Tchuja and Katuna Valleys from 3000 up 

 to about 5000 feet. It flies very rapidly close to the 

 ground m marshy spots and settles on damp sand or mud. 

 It is apparently very common in North-East Tibet, 

 as there were many specimens from Amdo m Grum- 

 Grshimailo's collection. It also occurs in the East Sayansk 

 and Apfelgebirge (Jablonnoi Mountains), where Domes 

 took it in 1896. 



178. Heteropterus morpheus, Pall. 



I found this only at one boggy spot by a river in the 

 Bija Valley near Lake Teletekoi on August 2nd, when 

 the species was much worn and nearly over. Ihese 

 examples have less markings on the upperside ot the 

 fore-wino- than in Europe, and the yellow of the underside 

 appears to be much less developed, but the specimens are 

 not fresh enough to say whether this distinction is constant. 



179. Augiades sylvanus, Esp. 



Small specimens of this species, much worn, were taken 

 near the Teletskoi Lake on July 31st. 



180. Adopmcb lineola, Ochs. 



I only found this myself in the Bija Valley at about 

 1500 feet on August 3rd and 4th, but Berezowsky sent 

 fresh specimens from Ongodai. 



181. Erynnis comma, L. 



I found this only in the Bashkaus Valley at 3000-- 

 5000 feet on July 24th and 30th, but judging from the 

 specimens sent to me by Berezowsky and Jacobson, it is 

 common at Ongodai. I see nothing in these specimens 

 to distinguish them from European ones, though Alpheraky 

 separates as var. mixta three specimens taken by him 

 at 8000—9000 feet in Kuldja in July.
