 inwards on vein 4 ; the basal area is slightly dusted with olive scales along costa 

 and inner margin. 



Hindwing : orange, paler along costa and broadly dusted with olive along inner 

 margin ; outer margin olive-brown, almost interrupted at vein 5 by the orange 

 ground-colour, which projects into it between 4 and 6.
