egos and the young larve that have not yet penetrated into the trees. 
Experiments to test the relative efficacy of (1) Scrubbing and (2) Scrub- 
bing and whitewashing have been conducted over nearly 4,000 plants. 
The results will be available next cold weather. 
The beetles are found in the spring also. Is there a second brood ? Mr. Anstead. 
That is only a case of deferred emergence. Mr. Kunhi

Have you found any natural enemies of Xylotrechus Mr. Fletcher. 
Two Hymenopterous parasites have been noticed. Their eggs are Mr. Kunhi

search of Xylotrechus grubs ; unfortunately I was not able to obtain 
specimens, but it was probably Xylonomus caerulescens. 
Regarding birds, one often sees bushes ripped open by birds, and the 
planters say that they extract the grubs of Xylotrechus. I cannot say 
what the birds are, but I imagine that they are woodpeckers of sorts. 
But the point that strikes one in the Coffee Districts, in Coorg at least, 
is the great scarcity of birds. This is undoubtedly due largely to the 
fact that the Arms Act does not apply to Coorgs and that the jungle 
tribes employed on estates carry bows and shoot and eat every bird 
they can knock down. It is quite common, in walking along a path 
through the coffee, to come across a few stones put together, with the 
remains of a fire and a few feathers scattered on the ground, to show 
where some small bird has been knocked down and cooked and eaten on 
the spot. So I do not think that birds are a very important factor 
in checking Xylotrechus, and as regards parasites these do not seem to be 
at all common. 
If we have heavy showers at the time eggs are being laid, the damage Mr. Kunhi 
caused by these beetles in the following season will be much less. Kannan. 
Are the eggs so loosely laid on the bark that they are washed away Mr. Ghosh. 
by rain ? 
I cannot explain this, but that is the general experience. 
that the result is due to the constant dripping of water along the trunks 
during the heavy rains. 
Would not the effect of rainy weather tend to reduce oviposition, as Mr. Fletcher. 
the female beetles only fly freely on warm, sunny days? I should think 
that is a more likely explanation. 
As regards the eggs, they are thrust right into the bark, usually 
under the loose pealeal that one finds on older coffee-bushes and would 
not be likely to be affected very directly by rain.
