242 PIEBIDJE. 



and abdomen dusky black ; beneath : palpi, thorax and abdomen 

 pale green. No sex-mark on either fore or hind wing. $ . Upper- 

 side, fore wing : ground-colour and markings similar to those in 

 the <5 but the dusky blacs area at base broader and the terminal 

 black band traversed medially by a transverse complete series of 

 whitish spots tinged with pale vermilion, the series curved 

 inwards opposite the apex and extended quite up to the costa ; 

 costa near apex and cilia very broadly orange-vermilion. Hind 

 wing : dusky black ; base clothed sparsely with long pale hairs ; 

 dorsum broadly yellowish ; discocellular spot and an incomplete 

 obscure subterminal series of small spots orange-vermilion ; cilia 

 dark pink. Underside : very similar to that of the d 1 , the colours 

 all somewhat brighter. 



Exp. <? $ 50-56 mm. (1-98-2-2"). 



Hub. N.W. Himalayas : Kashmir, Ladak, Chitral ; Sikhim : 

 Teesta Valley above 9000 feet; extending into Central Asia through 

 Tibet. 



Like many forms of this genus the female is dimorphic ; 

 specimens with the ground-colour on the upperside dull white 

 are in the British Museum from the Skoro-la in Baltistan. These 

 differ from typical eogene <$ as follows: Upperside, tore wing: 

 white to pale pinkish white, basal third thickly irrorated with 

 blackish scales ; terminal black band as in typical specimens, the 

 spots medially traversing it white with a tendency to become 

 obsolescent ; in one specimen, only one or two spots are left. 

 Hind wing : dusky black, the discocellular double spot fleshy pink, 

 the subterminal transverse row of spots more or less obsolete. 

 The pink line on the costa of the fore and the cilia of both fore 

 and hind wings as in typical specimens. Underside : like that of 

 ordinary specimens, but the green tints on both fore and hind 

 wings paler and somewhat greyish ; the fore wing, except at apex 

 and broadly on anterior portion of term en, greenish white to pale 

 dull pink. There are also aberrations of the $ from the Chonging 

 Valley in Ladak, with the colour and markings on the upperside 

 almost as in typical specimens, but on the underside the green 

 tints along the costa on apex and on termen of fore wing and 

 over the whole surface of the hind wing are replaced by grey.

cJ. Closely resembles in ground-colour and markings <$ of 

 C.Jieldi, but differs markedly in size, being always smaller. Upper- 

 side : black at base of both fore and hind wings, and an irroration 

 of black scales on posterior half of hind wing broader, darker and 

 more conspicuous than in C.fiddi. Underside: the green colour
