Promecotheca reichii Baly. 
This is a Hispid beetle whose larvae are leaf-miners in the 
leaflets of coconut. The egg is laid on the surface of the leaf, 
and the young larva, on hatching, bores into the leaf and feeds on 
the inner green part of the leaf, and producing a dead spot on 
the leaf where the green matter has been eaten away. The 
larva transforms to a pupa and eventually to the adult beetle 
within the mine in the leaf. This was not observed to be 
abundant enough to be particularly injurious. 
Leaf Caterpillar. 
Everywhere the coconut leaves showed evidences of the feed- 
ing of some insect which ate off the surface in small spots, 
leaving one epidermis of the leaf and giving the appearance of 
numerous small dead spots on the leaflets. No insects were 
found actually doing this eating, but it was considered as being 
the work of caterpillars of some small moth which was out of 
season at the time I was there. I thought at the time that the 
appearance of the leaves was different from that caused by the 
little moth, Levuana iridescens, which injures coconut leaves 
so badly in Fiji. 
Graeffea minor Br. 
Stick insects were found feeding somewhat on coconut 
leaves in a few places. In feeding they consume the whole 
substance of the leaf, so that the leaflets have ragged edges, or 
may even be eaten down to the midrib. A larger species, Graef- 
fea cocophaga (Newp.), is also said to feed on coconut leaves, 
but I failed to find any of these. The damage by these insects 
did not seem to amount to much. 
Chrysomphalus rossi (Mask.). 
This scale insect was found frequently on coconuts, occur- 
ring on or beneath the scales at the base of the nuts, also on 
other parts of the tree. It did not seem to be particularly 
injurious. 
Scholastes bimaculatus Hendel. 
This fly appears to be attached to the coconut, but perhaps 
not as a pest, as it apparently breeds in decaying nuts. The
