LED ID OP TER A INDIG A. 
Habitat. —Afghanistan, Beloochistan and the Himalayas. 
Distribution. —We caught it flying with Erate in the same localities and quite as 
numerous, and it appears to extend throughout the same regions. There are many 
more Albino females than in Erate; the types came from Cashmir; we have it from 
many localities in North-Western India.
