require. It is during the drying stage, therefore, whilst chemi- 
cal changes are taking place in the wood, that posts require 
protection, and although the matter is at present, I believe, 
little understood, it has been discovered that if the posts are kept 
in water after being cut whilst these changes in their interiors 
are taking place, their liability to attack by bostrichid beetles 
is apparently enormously decreased. My studies in this matter, 
as far as they have at present been carried, lead me to believe 
that this is not infrequently an undoubted fact, both in the case 
of wood and bamboos. 
I therefore recommend that, whenever possible, poles (and 
bamboos), when cut, should be— | 
(1) Felled (preferably) when the sap is down. 
(2) As soon as cut, placed in water, and kept there for 
some time. 
(3) If the latter is not possible, smoked as soon after 
felling as possible. 
Locality from where reported. 
The insect was found at Phandowalla in the eastern Dun 
forests of the United Provinces; elevation about 2,000 feet. 
It was also obtained at Seoni in the Central Provinces.
