Life History, ete. 
The larvz of this insect were found accompanying the defo- 
liators Dasychira sp. and Lymantria grandis in their great 
attack on the sal trees in the Goalpara district which com- 
menced towards the end of August 1897. The ZL. diaphana 
larvae were reported as very conspicuous during the first 
appearance of the other two, z.e., during the August-September 
generation, but after that to have been scarce. They were 
again noted in the January-February attack which was that of 
the third generation of the above two pests. What generation 
of the Z. diaphana \arve these February ones represented does 
not appear to have been noted. , 
We thus see that larve of this insect are found in August- 
September and again in February. The dates of the pupal and 
moth stages still require to be observed Also (2) what 
becomes of the insects between February and the end of 
August, (3) the number of generations it has in the year, and 
(4) where the eggs of the various generations are laid.
