If troublesome alb stems attacked should be cut and destroyed 
before the moth escapes. 
The Wolf Moth. Tinea granella, 
A bag of rice brought to the Garden was found to be infected 
with caterpillars to such an extent that it was quite useless, the 
small dirty white grubs lived in the rice grains, and spun them 
together with a web, nibbling them to dust. Having pupated 
the moth came out in a few days. It was about half an inch long 
entirely smoky grey. When at rest it rolls up its wings so as to 
appear quite cylendric and resembles a small piece of greystick. 
I suppose it to be the well-known Wolf moth, a regular godown 
pest in all warm places. It is said only to devour white rice, and 
the treatment recommended is to sprinkle the rice with salt. If 
.t becomes abundant in the godown, the rooms should of course 
be cleaned out and thoroughly cleared o^ the pest. 
The pumelo moth, Nephopteryx sagittiferella , Moore. 
A very complete account of this pest was published by Mr. 
Wray m the Journal of the Asiatic Society, Straits Branch, vol. 
XIX, p. 83, and it was described and named scientifically by Mr. 
Moore in Indian Museum Notes, vol. 2. The eggs are laid on the 
fruit, and the caterpillars eat into the rind, burrowing eventual- 
ly into the fruit and causing so much injury that the fruit falls 
before it is ripe. When full-grown the caterpillars descend to 
the earth where they pupate, and 12 days after escape as moths. 
The moth is brown with shading of silvery grey, and is about an 
inch across. 
I have seen what I suppose to be this animal in pumeloes in 
various places, and it quite destroyed all the lemons on a tree in 
the Botanic Gardens in Singapore some years ago. The most 
practical way of dealing with this animal is to constantly destroy 
all fruit attacked by it so as to prevent the caterpillars develop- 
ing into moths. 
The Padi borer Chilo. sp near Ch. oryzceellus , Riley. 
Is also described by Wray as destroying the paddy in Perak, 
lc. p. 73. The egg is laid on or at the base of a leaf and the cater- 
pillar tunnels the stalk and the midribs of the leaves and leaf- 
stalks. It pupates in the stalk or the leafstalk and hatches out 
into a pale ochraceous moth, nearly an inch across. It is very 
destructive, destroying whole acres of paddy. It is reckoned 
that there are six broods in the year. A parasitic larva, one of 
the Tachinid flies was found to destroy a quantity of them. De- 
struction of the straw and of selfsown rice by fire, after the har- 
vest was recommended. Another species apparently of the 
same genus was also found attacking padi by Mr. Wray but it 
was rarer. , 
The Sugar-cane Chilo, was described in Bulletin No, 7 > P- J 43 * 
The habits of all these grass borers are much the same. The 
caterpillar tunnelling the stem coming out at intervals and
