Cosmopolites sordidus, Germ., (Curculionidae) . 
This is reported to be a serious pest in other coun- 
tries, but has made little progress here. Damage 
is confined to the root and the base of the stem, in 
which the grubs bore. 
A banana plant which looks sickly should he in- 
spected and, if this weevil is present, the plant 
should be uprooted and burnt. All old stumps 
should be removed and destroyed and new suckers 
should only be planted if they are uninfected. 
Erionota thrax, Linn., (Hesperiidae ) . 
The caterpillars of this “ Skipper ” are to be found 
wherever bananas are growing, living inside the 
strips of leaf, which they roll up into a cylinder. 
They do little damage and are largely kept in check 
by numerous parasites. 
Pests of Citrus. 
At present citrus fruits are not grown on a com- 
mercial scale to any extent, and the pests have 
therefore received very little attention. 
Orpheides malayanus , Wallace, (Papilionidae ) . 
A number of Papilionid caterpillars feed on citrus 
leaves, but this one is most often seen. The whole 
life-cycle takes place on the plant. 
The caterpillars are not easy to see, and marked 
colour changes occur during their life. In small 
nurseries they are easily collected, while spraying is 
effective on a large scale. 
Attacus atlas , Linn., (Saturniidae ) . 
(The “Atlas moth”). 
■ Owing to the enormous size of the caterpillars 
of this moth considerable damage may be done in 
a short time. With careful supervision, however,
