Points in the life history requiring further observation. 
1. Where the eggs are laid. It is not improbable that the 
weevil makes small incisions in the bark with its 
proboscis and places its eggs in these. 
2. The time spent by the larva feeding in the bark of the 
tree before it gnaws out its pupating chamber in 
the wood. 
3. The life history of the insect from January to Nov- 
ember. How many generations in the year does 
it pass through and the length of time spent by 
the various stages of egg, larva, pupa and beetle, 
should there be more than one generation in the 
year. 
WOOD-BORING LEPIDOPTEROUS LARVA. 
Accompanying the weevil larve found in the bark of the 
Pinus Khasya trees as above described, a number of other and 
larger larv# were sent to me mixed up with the weevil grubs. 
These larger larvee are pink in colour with three pairs of 
jointed legs on the first three segments of the body, four pairs 
of sucker legs, one on each of the sixth, seventh, eighth, and ninth 
segments and another pair on the anal segment. The presence 
of these determines the larva to be a lepidopterous one, and it 
probably belongs to one of the wood-boring families of the 
fleterocera or moths. These larve require further careful study 
as they may prove todo as much, if not more, damage than the 
weevils. They were only found in the bark and were not full- 
grown. It will perhaps turn out that as they grow older they 
will leave the bark and bore into the wood, See. Pl, IV, fig. 8, 
I have recommended that some of the stems attacked by 
these larvae be kept under supervision with the object of 
obtaining the pupe and moths of the pest for identification. 
All other stems infested with the grubs should be cut out and 
burnt so as to stamp out the pest before the moths mature and 
issue from the trees to lay eggs and spread the attack to un- 
infested ones.
