and l)0(ly Ijlackish-brown, palpi and pectus beneath with white and grey hairs ; 

 abdomen whitish beneath. 



Female like the male, but with an extra white spot on the forewiug at the middle 

 of the sub-median vein, and all the spots larger, the pale space in the middle of the 

 hindwing somewhat paler. 



Expanse of wings, <J ? ly'^Q to l-j%- inches. 



Larva, cylindrical, with a flattened anal segment somewhat rounded at the 

 extremity ; the head is more or less round when looked at from in front and slightly 

 bilobed ; colour of head yellow-brown, with black mandibles ; eyes black, a red-brown 

 central Itand down the face, and a red-brown, crescent-shaped mark in centre of each 

 lobe ; the colour may vary from yellow-brown to brown-black, but is always somewhat 

 lighter on the vertex of each lobe. Tlie dark head is characteristic of the wet months, 

 the light of the dry season ; body covered with short, darkish, erect hairs ; longish 

 hairs round the margin ; colour of the body is a watery, dirty, dark green. Length, 

 31 '25 mm. 



Pupa, circular in transverse section, having large expansions to the spiracles of 

 segment 2, unmarked by spots ; slight boss between the eyes, surmounted by four fan- 

 shaped tufts of dense bristles ; eyes prominent, with short, erect hairs ; head liowed 

 slightly; segments 11 to 13 with tufts of hairs directed backwards on their lateral 

 margins ; cremaster short and square, with a short tooth at each hinder corner, clothed 

 along the maroin and extensor rido-es with lono-ish, dense, red-brown hairs which are 

 not hooked ; body covered with more or less erect, short, yellow hairs, a lateral row of 

 oval, flat, raised, dark brown, smooth tubercles; also a ventral row; on segment 11 

 there are three tubercles arranged in a triangle ; colour of thorax and wings green ; of 

 abdomen green-yellow ; a green dorsal line ; hinder edge of cremaster and teeth dark 

 brown. Length, 16 mm. 



Habits. — The larva builds a cylindrical cell tightly closed, by folding a leaf 

 lengthways, until the last moult, when it forms a cell by doubling the leaf transversely 

 across the middle, bringing the point up to the stalk and joining the edges loosely with 

 silk ; when about to pupate it eats the leaf free at the stalk end, and the cell falls to 

 the ground, where the pupation takes place. The pupa is in no way fixed inside the 

 cell. The larva feeds on bamboo. 



This insect is very common all over the district at all times of the year. It is fond 

 of water, and basks in the sun on leaves ; it may be easily caught when drinking or 

 basking, but is of extremely rapid flight and difficult to capture on the wing. We have 

 reared many, both in the monsoon and in the dry weather. (Davidson, Bell and 

 Aitken.)
