ii4 MACALLA MONCUSALIS. 


silk to the sides of the box and pupated inthis. It is pro- 
bable that this cocoon is spun on the leaves or twigs of the 
food plant in the forest. The insect spent 15 days in the 
pupal condition, a larva which changed into this state on 24th 
June issuing as a moth on July 8th. 
The time spent in the larval stage and the number of 
generations of the moth in the year have yet to be ascertained. 
Relations to the Forest. 
These larve were found in company with those of the 
Pyralid moth TZetridia caletoralis defoliating young sal sap- 
lings from 3 to 5 feet high in the Kriamba Reserve of the 
Ganjam District in Madras. The damage done, as far as it has 
at present been observed, has not been heavy. 
Protection and Remedies. 
In nurseries and plantations larve of this description when 
they become numerous, and therefore dangerous, are besttreated 
by spraying the young plants with the ‘arsenical compound 
Paris green. The method of doing this has been described 
€lsewhere. Dusting the plants over with a mixture of Paris 
green, unslaked lime, and ashés, as described for the ‘locust 
Tryxalis nasuta, might be tried as an alternative method. 
. Points in the Life History requiring further observation— 
1. Where the eggs are laid. 
2. Length of time passed in the larval stage by the June 
caterpillars. 
What becomes of the July moths ? 
. The number of generations in the year, 
What becomes of the insect 'in the winter ? 
. Does it feed on old as well as young trees ?
