its identity. It is a green caterpillar, probably a special cane 
insect, though not numerous enough to be considered a _ pest. 
I do not know if it feeds on other plants than cane. It occurs 
in Fiji, and quite widely distributed in the South Pacific. 
Cosmopteryx dulcivora Meyr. 
The larva of some small species of moth was found boring 
in the midribs of cane leaves, fairly common, but not specially 
injurious. I failed to rear any adults, but it is likely to be the 
species here given which occurs in Fiji with similar habits. 
Mealy bugs: Pseudococcus sacchari and P. calceolariae. 
Both of these species of mealy bugs are found, the former 
more common than the latter. Both feed on the cane stalk at 
the nodes, inside of the leaf sheaths. No parasites were found 
associated with these, nor ladybeetles feeding on them. 
Aleyrodes bergii (Sign.). 
In several different places colonies of an Aleyrodid were 
found on cane. They were usually on the underside of the leaf 
and near the base, and in quite dense clusters of a few hundred 
insects and occupying a space of two to three inches along the 
leaf. They were not numerous enough to cause any signifi- 
cant injury. This species also occurs in Fiji. 
Diaspine scale. 
In the cane patch at Fagasa, a few stalks of cane were 
found having a scale on them near the joints. Not numerous 
enough for injury. The species has not been determined. 
Coconut INSECTs. 
Oryctes rhinoceros Linn. 
The rhinoceros beetle seems to be considered the most 1m- 
portant of all insects that affect the coconut in Samoa. The 
injury is done by the large adult bettles feeding and burrow- 
ing in the growing crown of the coconut tree, where they may 
cause such injury as to result in the death of the tree, or they 
may only mutilate the undeveloped leaves so that they cannot 
become fully developed and of proper service to the tree, or it 
may be that the undeveloped fruiting clusters are so much
