E10 EUZOPHERA CEDRELLA and PHYCITA ABIETELLA. 

Life History. 
As far as is at present known the life history of both these 
insects is approximately the same. The eggs have not yet 
been discovered. It is possible that both the insects deposit 
them either on the twigs near the young female flowers or, in 
the case of the deodar, in the young flowers themselves as they 
are open in October. The eggs should be looked for between 
September and November. 
The larve make their appearance inthe spring, but the 
first part of their life history is unknown. The attack is first 
noticeable owing to the small holes surrounded by resin which 
make their appearance on the lower half of the cones —see PI, II, 
fig. 6e. I have seen these as early as May in the case of the 
deodar cones; in June in spruce, blue pine, and silver fir cones. 
On cutting up such diseased cones the larva will be found tun- 
nelling up or down them (depending upon the point of 
entrance), the seeds being often pierced through and eafen; 
the grubs will be found wallowing in the large amount of tur- 
pentine exuded by the cone through the wounds thus made. 
The long cylindrical spruce and blue pine cones become 
contorted into fantastic shapes under this attack. 
Towards the endof July and first part of August most of 
the larvae appear to be. full fed (though some are to be found on 
into September) and change into the pupal state. By this 
time the cone will have become so diseased that it will have 
fallen to the ground and some of the larva (if not all the 
species) leave it and enter the ground and pupate there. 
I think it probable that at least one of these larve 
migrates from coneto cone. I have usually found more than 
one grub in acone though there may not be more than one of 
any individual species present, the moths having only laid one 
egg near or on each flower. The mature insects appear on the 
wing between September and October. Specimens I bred out 
at Dehra Dun! issued as follows : on 12th September two moths 
from silver fir; 19th September moths from blue pine and on 
? The warmer climate of Dehra, of course, affected the period of issuing of 
the moths.
