Palpi projecting less than the length of the head beyond it; the second joint clothed, 

 obtusely thickened; apical joint short, exposed: antennae of the male slightly pubescent. 

 Fore wings — with the costa arched ; an appressed costal fold at the base in the male, a tuft of 

 long yellowish hairs projecting from the base of the costal fold; apical margin obliquely 

 convex — pale shining whitish straw-colour, with lustrous metallic streaks and spots, white 

 towards the costal and apical margins, steel-blue on the darker portions of the wing towards 

 the dorsal margin ; a wide umber-brown dorsal patch extending from before the anal angle 

 to the middle of the dorsal margin, and thence, with a slight interruption, less distinctly to 

 the base of the wing ; the base of the costal fold in the male is also shaded with umber- 

 brown ; and a spot of the same colour lies beyond the middle of the costa in both sexes : 

 these umber markings are all surrounded by a diffused margin of bright yellow, which 

 extends to the costa at a point a little before the middle. Hind wings greyish fuscous, with
