Reference :—Provisionally determined as such by Mr. M. Durrant. 
Classification:—Order, LEPIDOPTERA. Sub-Order, HETEROCERA, 
Family, Plutellide, Sub-family, Gelechinee. 
Description. 
Larva.—When full grown the larve are about half an inch 
in length, pale lemon yellow in colour and translucent. Head 
light brown. Body tapers towards posterior segments, the 
last two of latter having a dark coloured spot on their dorsal 
surface. A dorsal median brown line runs down the 8 anterior 
segments of the body. The colouring is the same in the young 
larvee, but the head is black and well developed, standing out 
on either side of the body, which is not the case in the full 
grown one where it is of the same width as the body. 
Pupa.—Anterior end black, abdominal segments yellowish- 
brown. Length slightly under half an inch. The pupa is 
contained within a loose net-work of fine silk which the larva 
spins across the inside of a leaf before changing to the pupal 
state. 
Moth.—Small, with narrow wings. Fore wings a pale yellow- 
ish-brown, fringed on their outer extremities. Under wings 
grey, their lower edges heavily fringed, a buff-coloured line 
running between the outer edge of wing and the fringe, 
Antenne filiform.

Life History. 
The larvz were found defoliating Sissu leaves on the 18th 
April and were then of all sizes, some being about full grown, 
My attention was drawn to the attack by the fact that the 
lower branches of the large Sissu trees were festooned with long 
thin strands of silky web which had caught and enclosed masses
