COLIAS. 241 



discocellular spot smaller than on the upperside and paler than the 

 ground-colour. Cilia of both fore and hind wings very pale vellow, 

 almost white. $ . Differs from the <$ as follows: Upperside, fore 

 wing: ground-colour generally orange, sometimes yellow or even 

 mealy-white ; terminal black area much narrower, transversely 

 crossed by a series (often incomplete) of diffuse ill-defined spots of 

 the ground-colour, that is indistinctly produced narrowly along 

 the veins towards the termen. Hind wing : the black on the 

 terminal area very irregular, exceptionally, covering only the 

 epical portion of the wing, often more or less extended towards 

 the tornal area but always broken and interrupted by yellow 

 diffuse spots which in some specimens coalesce and greatly though 

 very irregularly restrict the black area ; discocellular spot orange 

 as in the c? . Underside : as in the J ? but the basal half of the 

 fore wing in most specimens orange. Cilia of both fore and hind 

 wings rose-pink, that colour continued very narrowly along the 

 costal edges of both fore and hind wings and also along the dorsal 

 margin of the latter. In both sexes the antennae are rose-pink, 

 the head, thorax and abdomen either concolorous with the ground- 

 colour on the basal halves of the wings, or a little paler.

c? . Upperside : rich orange-vermilion. Fore wing : base, an 

 elongate discocellular spot and a very broad band occupying 

 nearly the terminal third of the wing dull opaque black, the last 

 widest at apex, its inner margin curved, irregularly waved and 

 produced narrowly along the dorsum for a short distance. Hind 

 wing : base and a broad area parallel to the dorsum dusky black, 

 clothed with long soft pale hairs ; dorsal margin itself narrowly 

 yellowish ; a broad, dull, opaque, black band widest in the middle 

 on the termen, its inner margin irregularly sinuate. Cilia of 

 both fore and hind wings salmon-pink. Underside : fore wing 

 orange-yellow ; the veins from base, the costa somewhat narrowly 

 and the termen more broadly suffused with green ; along the 

 termen this colour forms broad expansions at the apices of the 

 veins but is diffuse inwardly ; discocellular spot pink centred 

 with white ; an obscure, postdiscal, transverse series of black spots, 

 only the posterior two or three prominent ; a narrow edging to 

 the costa and the cilia pink. Hind wing : entirely suffused with 

 green ; a spot at base of cell, a large double discocelluiar spot, a 

 narrow edging to the costa and the cilia, pink ; the veins more 

 or less conspicuously greyish green ; a somewhat obsolescent 

 transverse postdiscal series of dark spots. Antennae and longish 

 liairs on the head above pink, club of antennas brownish ; thorax
