hind wing as distinctly angulated at apex of vein 4 as any of the 

 Southern Indian specimens. The width of the discal hand on 

 the upperside of the fore wing, the distinctness or otherwise of 

 the subbasal, postdiscal and subterminal transverse markings on the 

 upperside of the hind wing are all characters that vary among 

 the Southern Indian specimens themselves.

 markings ; head with two slender branched spines, succeeding 

 segments with on each side a lateral series .of semitransparent 

 .similar brown spines. Food-plant, Flacourtia sp. ?
