I do not see how more than one species of Kallima can 
be distinguished in Sikkim, though three have been 
separated by Moore, as well as others from Nepal and 
the North-west, only one of which, K. hiigelt, Koll., 
seems to me a good species. 
It is common in Sikkim up to about 5000 ft. from 
March to November, and varies much both in the extent 
to which the apex of the wing is prolonged and in the 
colour of the under side. This insect has been specially 
noticed by Wallace and later writers as an instance of 
protective resemblance to dead leaves, and this is, no 
doubt, very striking when settled with the wings closed ; 
but this is not the universal habit of the butterfly, which 
I have sometimes seen settled on a branch with the 
wings open, when it is a very conspicuous object.

D. polibete, Butt. Ind., ii., p. 268, t. xxiil., fig. 108, 3. 
A common species up to about 4000 ft. from April to 
December. It settles on rocks and banks of earth with 
wings closed, when it is hard to see, but not shy. 
The under side of this species varies very much in 
the same style of coloration as Kallima inachus; the 
prolonged hind wings also resemble a leaf-stalk when
