ground, in crevices under the bark of the tree trunks, or in the soil 

 underneath the trees. 



33. Experiments made by me showed that about 45 per cent, of the 

 larvae pupated on the leaves of the trees on which they were feeding, 

 55 per cent, leaving the foliage and pupating in any convenient crevice 

 under the bark, in dead leaves, or in the soil. The number of larvee 

 pupating on the dead leaves is about twice the number of those pupating 

 in the soil, provided there is an ample supply of dead leaves. 



34. An exception to the above remarks, however, occurs after the 

 hibernating stage, when pupation takes place usually, if not always, in 

 the ground. 



35. The leaves on which pupation takes place, whether dead or green> 

 are, so far as I have seen, invariably teak. On the green leaves the 

 larva usually takes up its position in a depression along the mid-rib or 

 a lateral vein, and there forms its cocoon, drawing the sides of the leaf 

 loosely together with the silky web. Occasionally, the cocoon is made 

 between two leaves which overlap, so that when these leaves are pulled 

 apart, the cocoon is destroyed. Still more rarely, the cocoon may be 

 made in the rolled-up edge of the leaf. 



36. On dead leaves, pupation usually occurs in the edge of the leaf, 

 which has become curled or rolled up, owing to the withering of the leaf* 

 The cocoons are also often made in a depression of the leaf surface as in 

 the case of the green leaves. 



Figs. XIX and XX show cocoons constructed in depressions on 

 green teak leaves. In both cases the cocoon is on the back of the leaf. 

 In the case of green leaves, suitable depressions are usually more fre- 

 quent on the back than on the front of the leaves. The cocoon, within 

 which pupation takes place, is of white silk and of a shape to fit the 

 depression in which it is made. 



37. When pupation takes place in the soil, the cocoon is made of 

 silk and bits of earth bound together.

38. Pupation may take place — 



(1) In the leaves of the tree, on which the larva is feeding. 



(2) In the leaves of shrubs or herbs growing beneath the trees 



attacked by the larvae. 



(3) In dead leaves, on the ground. 



(4) In the soil.
