The female of this species is a better mimic than the 6" , and only 

 differs from Delias eucharis in neuration and in the squareness of 

 the marginal red spots on under surface of hind wings.

Seems to come very near to P. vollenhovii ; but may perhaps be 

 a curious variety of P. autothisbe : I have never seen it.
