China. 



This species appears chiefly to differ from the female of 

 D. pyramus in the grey colouring and heavy black border of 

 the secondaries. I have never seen the species, and 

 Mr. Leech's work on the butterflies of China does not include 

 any of the species of Delias excepting D. belladonna and its 

 varieties.
