Life Htstory. 
This beetle appears about the beginning of May and com- 
mences to bore its galleries between the bark and wood of 
deodar trees, choosing by preference sickly trees, which, if young 
saplings, it bores into towards the base. In the case of older 
poles, it is found all over the stem. In the riddle of May 
young larve are to be found and the beetles from these would 
appear to issue about the end of July and in August. They at 
Once pair and re-start the work, and a fresh generation is gone 
through, larve being present through September and beetles 
issuing about October. Itis probable that a portion of the larve 
of this second generation hibernate as such, only a certain num- 
ber of the earlier developed ones going on to the beetle stage.

1This beetle was first reported as infesting deodar in the Bashahr 
Division, Punjab, in August 1g00, by Mr. Minniken, Deputy Conservator of 
Forests. Mr. Ribbentrop, then Inspector General of Forests, went up and 
studied the attack. Further notes on its life history were made by the 
writer in May-June 19o1.
