8 Indian Forest Records . [VdL. VHt. 
year ending 30th June 1918, 378,000 tons of teak were extracted, on 
which Government received 91J lakhs of rupees. As a rough guess, 
it would not be far wrong to say that, did the bee-hole borer not exist, 
Government would have received one crore of rupees on the same outturn, 
and the profits of the owners or buyers of the timber would have increased 
at least to the same extent.

Food-Plants. 
Teciona grandis, Linn., in Burma and Java. 
The writer has searched unsuccessfully for alternate food-plants 
in forests in which the borer was abundant, directing special attention 
to Gmelina arborea, Roxb. (Verbenaceae), because other borers of teak, 
viz., Haplohammus cervinus, Hope, Glenea galathea, Thoms., Pkassus 
signifer, Wlk. and others have been bred from it. The distribution 
records for Duomitus ceramicus beyond the habitat of teak may be 
questioned, but if correct they indicate undoubtedly the existence of 
other food plants.
