effect of checking this pest. I have said above that here 
and there the webs were to be seen on mulberry trees 
interspersed amongst the Sissu, but in no case did my 
observations show me that the mulberry leaves were being 
eaten. It is not improbable that the mulberry was merely 
used as a stepping-stone from one Sissu to the next. 
Points in the life history requiring further observation :— 
1. In what stage, egg, larva, pupa, or moth does the 
insect pass through the winter ? 
2. The duration of the first generation of the larva. The 
time when they first appear on the leaves should 
be ascertained. 
3. What happens to the moths which appear early in 
May? Where and when do they lay eggs, and when 
do the eggs hatch out? If in May or commence- 
ment of June, the length of time passed in the 
different stages of the subsequent generations 
requires watching. 
4. Number of generations passed through in the year.
