H&TEROGENOUS LARV& IN ACORNS OF Q. SEMICARPIFOLIE, 163 


Life History, ete. 
The above-described larvae were cut out of acorns which 
were not infested by the hymenopterous fly, 
Nos. t and 2,—The acorns from which these were taken 
were reaching normal size, being roundish in contour and 
green, touched with red on one cheek. They had holes on 
their outer surfaces and within I found as many as three larvae 
feeding on their contents, Never more than three were found 
and sometimes only two. 
No. 3.—This was cut out of an acorn which had turned 
dark brown in colour. It was feeding in the interior. 
This is as far as observations on these caterpillars have 
been carried at present. Unfortunately, though an attempt 
was made, no moths were successfull y reared from the larve. 
From the holes visible on the outer surfaces of the green 
acorns, it is probable that at least one of the larve wanders 
about during this stage of its existence and enters the acorns 
from the outside. In no instance was any trace of the 
hymenopterous fly found in acorns attacked by these three 
larve. If No. 1 is the same as the caterpillar (r) accompany- 
ing Callirhytis, its development would appear to be quicker 
when infesting acorns free from the fly, Further observation 
is required on this point. 
Points in the life history requiring further observation. 
1. Where are the eggs laid and when? 
2. Length of time spent in the larval stage by the 
various caterpillars, 
3. Where they pupate (is it in the ground after the 
acorn has fallen from the tree?), and length of 
time passed in the pupal stage. 
4. When the various moths issue and period spent 
in this stage.! 

1 T should be much obliged if specimens of these moths, when procured, 
were sent to me to Dehra Dun.
