COLIA.S. 235 



subcostal spot is large and prominent. Both fore and hind wings 

 with the cilia and a line on the margins salmon-pink ; this line on 

 the fore wing does not reach the tornal angle, on the hind wing 

 it is not extended to the basal half of the dorsum. Antennae, 

 head and thorax in front more or less salmon-pink, rest of thorax 

 and the abdomen yellow, strongly overlaid with greenish black ; 

 beneath : pale yellow, legs pinkish. $ . Very similar to the c? in 

 markings, but the ground-colour on both upper and under sides 

 may be either a paler yellow or white ; in both yellow and white 

 forms however, the spots of the ground-colour that traverse the 

 black on the terminal margin of the fore wing are generally 

 larger and sometimes more numerous than in the cT Anteuna3, 

 head, thorax and abdomen as in the c? . 



Exp. <$ $ 50-66 mm. (1-99-2-62"). 



Hab. Within our limits : Baluchistan ; the Himalayas from 

 Chitral, Kashmir and Kulu to Bhutan. It extends throughout 

 the Palaearctic Region except the extreme northern portions. 

 It is not found in the Canaries. 



Larva. In Europe : " Cylindrical, dark green sprinkled over 

 with black dots ; there is a narrow yellow and white lateral stripe. 

 Feeds on Leguminosce, principally Trifolium" (Lang.) 



Pupa. " Green, with a brownish- yellow lateral stripe." (Lang.} 



Var. erate, Esper, seems to be, as noted above, so far as the 

 males are concerned a dimorph of hyale. As to the females, 

 in any large series it seems impossible to separate them from 

 those of hyale. 



Var. clirysodona, Boisduval, has been considered by some 

 authorities as a hybrid between C. hyale and C. croceus, Fourcr. 

 = edusa. Fabr. It differs from hyale, dimorph erate, chiefly in 

 the ground-colour of the wings, which on the upperside are a 

 rich chrome-yellow, not lemon-yellow. 



C. helichta, Lederer, is a synonym of chrysodona. 



Var. sarcptensis, Staudgr., was diagnosed as follows : " Al. 

 ant. marg. post, lato nigro ; c? satur. flavus." The width of the 

 black terminal band on the fore wing is very variable in hyale, 

 as is also the depth of the yellow tint in the ground-colour. 



C. lativitta, Moore, is a synonym of the dimorph of hyale, 

 C. erate. The type is in the British Museum, and a close com- 

 parison shows that it can be matched by many specimens from 

 {$. Russia, where erate first begins to make its appearance. 



Race nilgiriensis, Felder. Closely resembles typical hyale, but 

 as it is isolated in the hills of Southern India it has acquired a 

 distinguishable general appearance. d" Upperside : ground-colour 

 a deeper, brighter yellow ; irroration of black scales at base of fore 

 wing much more extensive and on the hind wing spread right up 

 to the black on terminal margin ; terminal black border to both 

 fore and hind wings proportionately broader ; on the fore wing 

 traversed as in the typical form by a transverse series of yellow 

 spots. Underside : ground-colour a brighter yellow than in hyale,
