greatest about the 3rd or 4th and Oth or 10th segments, varying a 

 little with position. It moves as freely backwards as forwards, the 

 whole ventral surface adhering closely to the branch, so that head and 

 legs are seldom visible. The colour is clear green, with or without a 

 brown bar on each side of the 10th segment. The pupa is thick and 

 short, humped on the thorax, and somewhat constricted behind ; 

 light brown mottled with darker. 



There were no ants with these larvae when they were brought to 

 us, but after they became pupae they were discovered by a nest of 

 common house ants, and were immediately put under a guard and 

 carefully watched. But we shall have more to say on this subject 

 under the next species.

The larva of this species, which we found from June to October on 

 Terminalia paniculata, one of the commonest jungle trees in Canara, 

 has the usual wood-louse form, the head being concealed under the 

 2nd segment, and the sides extending beyond the legs, but it is 

 proportionally longer and flatter than most of the f amity, and the last 

 two segments are much depressed. There are a few strong, black 

 bristles about each spiracle, and below these a fringe of similar 

 bristles skirting the whole outline of the insect as seen from above. 

 There is a honey gland on the 1 1 th segment, but we saw no signs 

 of erectile organs on the 12th. The colour varies a little, but is 

 usually green below and on the sides, the whole back being of a 

 fine, reddish- brown, very prettily marked with darker and lighter 

 shades. The pupa is stout and broad, with the thorax humped, and 

 the under-surface very flat. The last segment is peculiarly prolonged 

 and expanded : to describe it appropriately a Greek word is required 

 signifying, — having-the-form-of-a-horse's-hoof. By this alone the 

 pupa is firmly attached to a strong web of silk in a loose, half-open, 

 leaf- cell. 



We never found either larva or pupa of this butterfly without an 



attendant guard of the ferocious red, or yellow, tree ant, GEeophylla

kept with the larva in a bottle, lived quite happily for a week, and 



seemed to require no food besides what they obtained from it and
