outer margin broadly black, irregularly dentate on nervules on its 

 inner edge, with the following sulphur-yellow spots, viz., five 

 forming a curved row near the apex from costa to 3rd median 

 nervule, the lower two being larger than the upper thi'ee ; also 

 one spot between the 1st and 2nd median nervules, and one 

 between the 1st median nervule and the snbmedian nervure; cilia 

 of both wings whitish with a pink suffusion. Hind wing black, 

 basally thickly irrorated with snlphur atoms ; an orange spot at 

 end of cell ; anal and outer margin sulphur-yellow, which forms 

 into a line of lunular spots on outer mai-gin. Body black, head 

 and antennae pink. Under side : fore wing — disk pale yellow ; 

 apex and outer margin grass-green, with a submarginal line of 

 pale yellow spots ; a black spot at apex of cell, and three black 

 discal spots in a row between the median nervules and submedian 

 nervure. Hind wing grass-green, paler on outer margin, and 

 irrorated with black atoms ; a silver spot surrounded by a pink 

 area at the apex of the cell. 



This species belongs to the hycde section of the genus Colias, 

 and is nearest to C. ersclioffi Alpheraky, from the Tian Shan Mts.

Description. — Female. Upper side : fore wing pale sulphur- 

 yellow, the disc .below the median nervure and 3rd median nervule 

 orange ; a black diamond -shaped spot at apex of cell ; a broad 

 black outer marginal band, inwardly irregularly dentate on the 

 nervules, irroiuted with sulphur-yellow scales outwardly, and a 

 submarginal row of ill-defined sulphur spots between the nervules, 

 that between the 2nd and 3rd median neiwules being obsolete. 

 Hind wing black, irrorated with pale sulphur atoms, most thickly 

 towards the base and outer mar-gin ; discoidal cell pale yellow, 

 with an orange spot at its apex ; a submarginal row of pale 

 sulphur hastate spots ; antennee and cilia pinkish. Under side : 

 fore wing — disk as on upper side ; apex and outer margin pale 

 green, irrorated with black atoms ; a black spot at apex of cell, 

 and three or four ill-defined black spots discally between the 

 nervules. Hind wing pale green, with spots as on upper side. 



This species appears to be a transition between the hyale and 

 editsa sections of Colias.
