stripe ; hind margins of clasper faces broadly reddish-brown. 

 Horn dull, deep reddish-brown. Spiracles oval, very dark 

 reddish -brown, with central slit white. 



Pupa. — Very similar to those of M. dyras and M. indicus in 

 shape, surface and colour ; ante-spiracular ridges present on 

 segment 9 only ; surface of abdomen more coarsely corrugate 

 and pitted than in dyras. 



Habits. — Food-plant : Alseodaphne semicarpifolialSees. family 

 Laurinea?. Habits of larva similar to that of dyras. Bred $2 

 attract wild $$ late at night. All the specimens known to us 

 were bred from a captive $ at Karwar, S. India ; this $ attracted 

 several $£ and mated with one of them. A large series of 

 moths were obtained from the eggs laid by her, the larvae 

 being put on a tree covered with gauze and protected from 

 ants by a cloth soaked in kerosine-oil tied round the trunk.
