Tliis is a very variable form beneath, but the throe varieties described appear to rein-(>!^ent 

 the species iu the Malay Peninsula. In other habitats different varieties are found. 



The larva and pupa as found in Ceylon are described and figured in Moore's ' Lepidoptera 

 of Ceylon,' from drawings made by the Bros, dc Alwis. The shape is that of the larva of 

 M. leda, the "head large, surmounted by two short pubescent red processes, last segment also 

 with two processes ; pale green with longitudinal rows of whitish dots ; dorsal and lateral line 

 darker green ; head bluish, face striped with white and black. Pupa green, cylindrical ; head 

 and thorax obliquely flattened." * 



Its habits in Continental India were described with those of .1/. leda by Capt. Lang and 

 Capt. de la Chaumette {ante p. 42) ; and, in the neighbourhood of Monghyr, Mr. Lockwood tells 

 us that when "the toddymen cut the date trees," hundreds of this species "coUect to feed upon 

 the sweet sap, in company with many yellow-banded wasps and ants." f

Anterior wings short and broad, witli tlie costa strongly arched and apically convex, and the apex 

 rounded ; outer margin slightly waved and concave ; inner margin straight ; costal nervure dilated at base ; 

 first and second subcostal nervules emitted before the end of cell ; upper disco-cellular nervule short, 

 directed outwardly at base and then somewhat concavely bent and directed outwardly along its greatest 

 length ; lower disco-cellular nervule nearly straight and directed outwardly. Posterior wings irregularly 

 subovate, with the outer margin waved and produced into an obtuse angle or tail near first median nervule ; 

 first and second median nervules with a common origin about apex of cell ; disco-cellular nervules about 

 or almost subequal in length. Eyes prominent and hairy. Palpi clothed beneath with fine long semi-erect 

 hairs, distinctly separated — setose. Autennre more or less inerassated at ai)ex. 



Above forty species of this genus have been described. It is strongly represented in 

 Continental India, is not uncommon in the true Malayan Region, and is found as hir north as 

 China and Japan. 



Only one species has at present been received from the Malay Peninsula, and is here alone 

 included.
