<S . Upperside : lemon-yellow ; costa of fore wing, base of both 

 fore and hind wings and the posterior half of the latter, irrorated 

 with black scales ; on the hind wing the black scaling does not 

 extend to the tornal angle. Fore wing : a small oval discocellular 

 black spot ; the apex and termen broadly black, broadest on the 

 apex, gradually decreased in width towards the tornal angle, to 

 which in a few specimens it does not quite extend ; this black 

 border traversed (sometimes immaculate, eastern dimorph erate) 

 by a transverse series of five or six spots of the yellow ground- 

 colour. Hind wing : discocellular spot double and of a deep 

 orange-yellow ; terminal margin black, the black forms a con- 

 tinuous band (dimorph erate) or is more or less irregular and 

 often interrupted or broken into terminal spots : it extends 

 from vein 2 to apex of wing. Underside : lemon-yellow, the base 

 and costa of the fore and the basal half or more of the hind wing 

 very lightly irrorated or sprinkled with black scales. Fore wing : 

 discocellular spot as on the upperside, and a postdiscal transverse 

 series of black spots that decrease in size, curve inwards, and 

 become reddish in colour anteriorly. Hind wing : discocellular 

 double spot silvery, each spot with a slender red inner and outer 

 ring, in some specimens each spot has only the inner ring, and 

 the two together are encircled by an outer slender ring ; a post- 

 discal curved, somewhat obscure series of red spots, of which the
