refused any leaves of Mahwa, except those of the identical 

 tree on which they were found. 



The pupa and cocoon are very similar to those of 

 M. venustiun, but the latter is not marked with cross- 

 bars outside, or quite so hammock-like, and it is of 

 thinner silk. 



The male imagines have abdomen longer than wings, 

 and a curious porcine aspect about head and thorax. 

 The females resemble those of M. renustnm, except in 

 colouring. Both sexes rather more active than those of 

 former species, but evidently very closely allied.

Larva feeds on the leaves of Pipal {Ficus religiosa). 

 General ground colour a soft pale brownish grey, diver- 

 sified with pale ochre-brown puucta and markings. A 

 soft spine on dorsum at caudal end. 



Cocoon of a cylindrical shape, attached by one side to 

 leaf, and also secured by a web of loose silk netting 

 above it ; it is formed of yellow silk, and is of firm 

 texture. 



Pupa not particularly noted. 



From a cocoon made on August 18th the imago came 

 out on August 25th. Body and wings of a soft pale 

 French grey. Antennae plumose, hooked at the end. 

 The wings are extended horizontally when at rest. The 

 medial and posterior legs are without spines.

The larvae feed on the leaves of a tree called " Jaman" 

 by the natives. They have a very peculiar ajipearance, 

 owing to the large bladder-like expansion of the 1st 

 segment of thorax. This appears capable of contraction 

 and dilation at will ; in the latter condition the head is 

 almost concealed within it. 



The cocoons arc formed of strong yellow silk, of an
