Life History} 
The larve are full fed at the end of the third week in June 
and pupate by spinning themselves up in a portion of a leaf of 
the food plant by means of a white silk. Within the covering 
they turn into pupz. About 15 days is spent in this stage, 
larve2 which pupated on 23rd June issuing as moths on the 
7th July. This is at present all that has been reported on the 
life history. We still require to know the length of time the 
June larve spend feeding and the number of generations of 
the insect there are in the year. 
Relations to the Forest. 
The larvze of this insect defoliate the sal (Shorea robusta) 
in Madras. They were found feeding on sal seedlings from 
3 to 5 feet high in the Kriamba Reserve of the Ganjam District, 
The damage done, as at present observed, has not been very 
heavy. It is found feeding in company with Macalla moncusalis, 
Wik. 
Points in the life history requiring further observations :— 
1. Where are the eggs laid? Isit on the branches of 
the sal trees? 
2. Length of time passed in the larval stage by the June 
caterpillars. 
3. What becomes of the July moths ? 
4. The number of generations in the year, 
5. What becomes of the insect in the winter ? 
6. Does it feed on old as well as young trees ?
