Life History. 
This small Scolytid bores into branches and twigs of the 
deodar, which from any cause are ina sickly or dying condition, 
and lays its eggs in the green bast layer. It will not touch 
dead twigs. ‘lhe insect is almost invariably found in branches 
girdled by the Deodar Branch Girdler (p. 220), the girdled and 
dying branch being in just the condition it prefers for egg-laying, 
In attacking a stem a beetle, probably the ¢, bores horizon- 
tally through the bark down to the cambium layer hollowing
