interior of the cane for two or three segments, so destroying it, or ants get m 
and probably by carrying in and depositing earth set up destructive 
decay. 
The first borers were noticed in cane about 4 months old. The older 
the cane the larger the proportion attacked. In ratoons practically every 
cane is affected. J 
. oird causing some diminution of the growth is 
comparatively harmless. It is identified by Mr. Robinson as a Crambid. 
In Pahang none of the borers which were found in Province Wellesley 
and Selangor were found. In a few canes on the East Coast a lepidopterous 
larva, according to Mr. Ridley, a Pyralid, does occur, but the destruction 
caused is small. It has not been found elsewhere in the Federated Malay 
States. J 
It is noteworthy that the native varieties of cane are far less attacked 
by these pests than the imported varieties. 
The original source and native habitat of these borers is unknown. The 
wild Saccharum arundinaceum is not attacked. 
Scale insects are abundant in the axils of the leaves and appear to cause 
some destruction in ill-kept badly cleaned canes. 
I ill full information is obtained as to the distribution of the pests and 
particularly of the Zeuzerid larvae great care should be exercised in moving 
canes from one place to another or this pest may be introduced and possibly 
under European conditions of cultivation thrive in districts at present free | 
from it. I do not believe that on a large scale cane could be economically 
grown in any district where this pest occ urs. 
Indian Corn, Maize, Zea mais , is not very extensively grown. It is not 
as in Africa the staple article of diet of any class. It grows well in manured 
land and can be cropped in from 10 to 14 weeks according to the weather, 
k ew pests seem to cause much damage but the cobs are frequently attacked i 
when nearly mature by a lepidopterous larva which in its passage up the 
cob destroys a certain number of the grains. The dry cobs are attacked by ! 
weevil, probably, according to Mr. H. C. Robinson, a Calandrid. 
Millet, Sorghum vulgave —Like Indian Corn is only grown as a subsidiary 
article of diet. The native varieties have few and poor heads with small 
seeds. A W est Indian variety introduced has numerous heads and large j 
seeds and grows rapidly and affords an abundant crop. The young shoots 
are often destroyed by mole-crickets, and one of the few aphides found in the 
country is found on this plant. 
The heads and nearly mature seeds are the parts most subject to 
disease and are attacked by two larvae of lepidoptera both belonging to the 
Pyralid family as identified by Mr. Robinson. These heads are also 
liable to be attacked by fungus (smut) but whether secondarily to the 
attacks of larvae or not could not be ascertained. The native variety of 1 
millet is not attacked by these insects. 
The flowering stalk is often hollowed out by an adult hymenoptera or 
solitary wasp, a Sphegid. 
Fruits of various kinds are subject to great variety of insect pests. 
1 he grenadilla, Passiflova quadrangularis, is much infested by Thrips in some 
cases and these destroy the pollens and tips of the stamens, according to 
Dr. Leicester, and so prevent fertilisation. Only some vines are so 
infested. WTen nearly mature dipterous larvae are found in the thick seed
