Lepidoptcra of the Altai Mountains. 321 



27. G. thisoa^ Men., and G. crate, Esp. 



Both taken by Ruckbeil but not seen by me. I do not 

 know the exact localities where he got them, so perhaps 

 they should not be included, though some species of the 

 thisoa group ought to occur in the Altai Mountains. 



28. Bhodocera rhamni, L. 



Hybernated specimens were common from the time I 

 reached the Obb river up to Ongodai, and fresh ones were 

 first seen in the Bija Valley in the beginning of August. 



29. Thecla hctidx, L. 



Not seen by me, but apparently not uncommon early 

 in August at Ongodai, where Jacobson got several 

 specimens not differing from European ones, except that 

 the females show a little less yellow on the fore-wing. 

 A specimen from Lake Teletskoi was in the St. Petersburg 

 Museum. 



30. T. ijrunoides, Stgr. 



I found this in the valley of the Tchulishman river at 

 about 3000 feet at the end of July, and Jacobson also 

 took it at Ongodai. At first I supposed this to be W- 

 album, but on comparing it with Dr. Staudinger's collec- 

 tion, he considers that my specimens are tlie same as 

 primoides from Amurland. He had one taken by Kinder- 

 mann at Ust-Kamenogorsk in the South- West Altai. 

 The species is easily distinguished from W-alhum by the 

 absence of the well-marked sexual patch on fore-wing of 

 the male, which is constant in that species. 



31. T. jjruni, L. 



Recorded by Kindermann, and I have one from Qrum's 

 collection, taken near Semipalatinsk. 



32. T. ruU, L. 



Taken at Biisk, Ongodai, and in the Tchuja Valley up 

 to about 4000 feet in the first half of June. 



33. T. frivaldszlcyi, Led. 



I found this in bushy places in the Katuna and Tchuja 

 Valleys, at 3000 — 4000 feet, in the second week in June. 

 It is evidently an early spring insect, as many of the
