in colour with a spongy-looking surface ; proboscis produced free to 

 hinder margin of segment 9 ; surface finely rugose, with short hairs 

 from segment 8 to end of dorsum; some longish, stiff hairs on front 

 of the head and round the eyes ; colour light green, strongly suffused 

 with red-brown, especially on the top of segments 1 to 3. 



Habits. — The larva makes a cell as above described for the group, 

 and eats the leaf above at the base, leaving the cell attached by the 

 midrib to the stalk ; often, finally, the cell falls to the ground, where 

 the larva pupates inside it. The larva feeds on bamboos, chiefly on 

 Teinostachyum, the egg being laid always on a leaf near the ground.

The butterfly is very common in this district, more especially 

 during the latter part of the rains, in the months of September, 

 October and November ; it is never, however, scarce ; it frequents 

 shady places in the thick, damp jungles, and keeps generally near the 

 ground. We have bred the insect often. 



Larva. — Head as in the group ; colour of head dirty whitish-yellow 

 with a red-brown marginal band meeting the opposite one on the 

 vertex ; an impressed brown line from the vertex to the apex of the 

 clypeus, and a short brown line parallel to this on each side of it 

 running from the centre of the clypeus to half-way up the face ; 

 clypeus light brown, with a dark brown line from the apex to the 

 base ; jaws dark brown ; shape of body as in the group ; colour of 

 body is a watery-looking green, on the sides yellow, dorsally spotted 

 minutely with green ; a dorsal and subdorsal dark green line ; surface 

 oily-looking. The hinder edge^of the last segment somewhat shortly 

 hairy. Length 275 mm. 



Pupa. — Similar to the last ; cremaster shortly triangular, pointed, 

 with a single bunch of hooked hairs at extremity ; spiracular ex- 

 pansions of segment 2 raised slightly, semi-circular, facing forwards ; 

 dark brown in colour ; proboscis produced to the end of segment 9 ; 

 surface slightly and shortly hairy. Length 15 mm. 



Habits. — The egg is laid on the upperside of a blade of grass or on 

 a bamboo leaf near the ground ; it is nearly smooth to the eye, dome- 

 shaped, rather higher than broad, and of a dark red colour. The 

 larva makes a more or less lax cell at first, but finally a very tight one by 

 joining the leaf by its edges longitudinally ; the larva will often lie on
