PLOCEDERUS OBESUS. 371 

practical protective measures against it are enforced. Feasible 
ones in the case of fellings made in compact blocks, either of 
high forest or coppice areas, are :— 
(1) Bark all felled trees before April or during that month. 
(2) Remove fuel stacks of unbarked wood and unbarked logs 
from the neighbourhood of the forests by the end of 
April. 
If the above operations are strictly enforced, the danger of 
this beetle increasing in such numbers as to form a menace to 
the forest will be slight. 
Points in the life-history requiring further observation. 
Does the insect take less or more than one year to pass 
through the various stages of its life-history— 
(1) At the upper limits of Sal (Odina Wodter), etc.,. 
growth at high elevations ? 
(2) In the hotter and damper parts of the country ?
