Zepid&ptera of the Altai Mountains. 32S 



40. P. jjldmas, L. 



A single specimen taken at Biisk early in June. 



41. P. amphidainas, Esp. 



Common near Altaisk, and up to about 3000 feet, in 

 the first week of June. 



42. Lycmna argiades, Pall. 



The first generation was common at Biisk in the first 

 week of June, the second, much larger, was out in the 

 Bija Valley the first week in August, 



43. L. fischeri, Ev. 



Very abundant in the valleys of the Katuna and Tchuja 

 from 2500—3500 feet in the middle of June. The 

 species swarmed on wet sand and damp places by the 

 side of the river, where it could often be taken without 

 a net. The second generation, which does not seem 

 appreciably different, appeared at the end of July in the 

 Bashkaus Valley. Jacobson also found it common at 

 Ongodai after I left. 



44. L. legon, S. V. 



Common at Ongodai and in the Tchuja and Bashkaus 

 Valleys in July. Some of the specimens from Ongodai 

 are very dark on the upper side, and might be considered 

 as a small variety of cleobis, Brem., which is found in 

 the Kentei Mountains and Mongolia, and of which I 

 have specimens from Alphei'aky from Irkut, and from 

 Uliassutai under the name of var. ida Stdr. agreeing 

 fairly with mine. Staudinger also says that he has from 

 Minusinsk a form of deohis nearly approaching argus. I 

 do not, however, know of any certain distinction between 

 the three species, though a majority of them can be 

 recognized, and deohis seems darker below than argus, 



45. L. argus, L. 



Not uncommon from about 3000 — 6000 feet from the 

 middle of June. Staudinger refers his Kentei specimens 

 to var. planorum, Alph., but I do not know how that 

 so-called form can be distinguished, and it is evident that 

 the variation of such a wide-ranging species as this is in 

 all parts of Europe and Central Asia will require very
