The numerous variations to which the females of this 
species are subject have rendered its synonymy rather 
intricate, but, as the question is ably worked out by de 
Nicéville in the ‘ Butterflies of India,’ I need not refer to 
them at length. 
The variable form isa, which mimics Huplwa rhada- 
manthus, and the more constant form nyctelius, which 
mimics 17, midamus, male, are both found in the valleys 
up to about 8000 ft. with the male, which does not seem 
to vary, from April until the end of the year, but are 
not abundant at any season. 
Dilipa morgiana has been taken in Bhotan by Mr. 
Knyvett’s collectors, but has not yet been recorded from 
Sikkim.
