STROMATIUM ? sp. 383 
BEEP) eee ee EE 
it was apparent that a number of the trees had been attacked 
some years previously by a cerambyx borer, not improbably the 
Stromatium, About 4,000 badly shaped or dying and dead 
trees had been cut out the year previous to my visit (190r) 
or it is not unlikely that the evidence of the pest’s work 
would have been still greater. 
Summarising the above we see that this pest may— 
(1) Kill saplings (probably not often) ; 
(2) Bore up the heart-wood of young living trees. That 
subsequently the vitality of these latter is sufficient 
-to grow over the air and exit-holes, thus hiding all 
trace of the attacks which are only discovered when 
the wood is converted for sale. 
(3) The exit and air-holes may “ weather”’ tosuch an extent 
that they coalesce, and thus 50 per cent. or more of 
the heart-wood of the tree may be destroyed. 
During a visit I paid to the Sandal Koti at Bangalore, I was 
able to inspect the damage done to the wood by these insects. 
Unfortunately I arrived a week too late to be present at the 
actual sorting of the year’s outturn which was stored in the 
godown. Had Ibeen present at thisit would have enabled me to 
have inspected many hundreds of logs, and it would have been 
possible to form some conclusion as to the insects’ abundance or 
otherwise in Mysore. I was shown the various classes of wood 
and the system of classification was described. Wood with 
holes and galleries in it, even though its quality may be other- 
wise absolutely 1st class, is relegated to the 3rd or Ath classes, 
and therefore it is quite possible to calculate the actual 
monetary loss occasioned by the work of this longicorn. My 
inspection showed it to be sufficiently high to render the full 
working out of its life-history a matter of the first importance. 
Norz.—In a tree with a diameter of 6 inches at the base I found another 
kind of longicorn larva which is not a Stromatium. ‘The tree, a large one 
standing in the Odayarpalaiam compartment of the Doddasanpige Forest, 
had a dead 5 foot top. Below this in the green wood I cut out a longicorn 
grub, about 1} inch long, white but with much larger thoracic segments 
than has a Stromatium larva. A second one was found lower down in 
the bole. Nothing further has been ascertained about this grub. It 
would not appear to be so numerous as the Stromatium, as only
