(S ? . Second segment of palpus strongly narrowed towards base, triangular 

 (PI. LIX. f 17), entirely different from the segment of velata, aurijera, etc. ;

 the first protarsal segment doubled and trebled. In colour resembling aurt/'erc, 

 the subdorsal tawny-ochreous stripe of the abdomen at least vestigial ; underside of 

 thorax and abdomen buff, less white than iu aurij'era, the discal dots of the 

 forewiug below smaller, the marginal area not joined to the basal one ; the 

 marginal area of the hindwing narrower, not so much dilated before R'. There 

 are two forms connected by intergradations, but the intermediate examjiles are 

 comparatively rare. In one form the ochreous-buff band of the hindwing is reduced, 

 being often just indicated near anal angle ; the forewiug has scarcely a yellow 

 tint, and the underside of both wings is dull clayish ochraceous with a tint of 

 brick-red. Iu the other form the forewiug has here and there an olive-yellow
