Ckunibi Valley, east of Native Sikhim. Beyond our limits this 

 species is widely spread in the Palgearctic Region, being found 

 from Lapland to Russia, also in Siberia, the Altai Mountains and 

 N. Mongolia. 



Spread over an immense range it is necessarily a variable form, 

 but specimens from both the Western and Eastern Himalayas can 

 be matched by others from Norway and B-ussia. Some of the 

 Sikhim specimens have the underside of the hind wing more 

 strongly suffused with the reddish colour than others, but similar 

 specimens from Norway are in the Elwes Collection, now in the 

 British Museum. 



Race generator, Staudiuger. — Closely resembles pales, but is 

 distinctly larger in both sexes, the ground-colour on the upper- 

 side paler and brighter, the black markings much reduced in size. 

 Underside similar to that in pales but paler, the ground-colour on 

 the hind wing being very pale yellow, almost white in some 

 specimens, the silvery-white markings are much less couspicuous 

 and the reddish much paler. A series from the Hindu Kush 

 range and from the Tian Shan and Transalia Mountains show 

 little or no variation. Chitral specimens seem to run somewhat 

 smaller. 



Exp. tf 2 49-51 mm. (1-93-2-01"). 



Hob. Within our limits the Hunza Valley ; North Ladak ; 

 Chitral. Found in Turkestan and Afghanistan.

S . Upperside tawny, markings black. Fore wing : base dusky 

 brownish black ; cell with a minute spot, sometimes 2, at base; a 

 sinuous, short, medial transverse line, and another at apex along 

 the discocellulars ; a spot, sometimes a transverse line, below the 

 the cell in interspace 1 ; the usual biangulated series of discal 

 spots ; a black, transverse, short mark at base of interspace 7, 

 extending into 6, and a postdiscal series of round spots ; the 

 terminal margin and apex narrowly black, the former traversed 

 by a series of small lunules of the ground-colour ; cilia white, 

 alternated with black. Hind wing : base and upper half of dorsal 

 margin very broadly dusky brownish black ; cell with a minute 

 spot at base and a loop-like mark near apex ; a zigzag discal series 

 of spots; a postdiscal curved transverse series of round black 

 dots ; a series of triangular subterminal small spots and the 

 terminal margin narrowly black; the subterminal spots often 

 coalescing with the black margin along the veins. Underside : 

 fore wing ground-colour paler tawny, apex pale ; black markings 

 as on the upperside, but the anterior two or three spots of the 

 postdiscal series centred obscurely with white ; the narrow black 

 terminal margin reduced to a subterminal transverse series of very
