Hah. Calcutta {Atlinson Coll., Brit. Mus.). 



The British Museum possesses three examples of this species 

 which is allied to I. chipealis, Leth. It remains to be proved 

 whether it is only an extreme variety of that species, though I do 

 not think it can be, or at least T do not feel justified in treating 

 it as such.
