APODERUS INCANA, MS. 191 
liated when the weevil is numerous, Trees of all ages are in- 
fested, and it is the new just unfolded leaves which are primarily 
treated in this manner, the dlder ones being only resorted to 
after the newer ones have been all occupied, PI. VIII, fig. 7, 4, 
shows a portion of a branch with the upper leaves defoliated 
by this insect. 
In t901 the insect was very plentiful and large numbers 
of the leaves of the two oaks were treated in this way. The 
insect was less plentiful during the present year. In 1896

These will be the same as already given on p. 36 of these 
notes for the Sissu Apoderus. 
Points in the life history requiring further observation. 
1. The number of eggs laid by each¢. 
2. The food of the@?. 
3. Does the larva eat anything besides the little leaf roll 
prepared for it by the 2 ? 
4. Length of time spent in the larval stage, 
5. Length of time spent in the pupal stage. 
6. ls there more than one generation in the year, 7.¢., is 
the summer flush of leaves attacked in a similar 
manner ? 
Note.—In the same locality beetles of the genus Apoderus 
have been found rolling up the leaves of the wild pear (Prunus 
Padus) and the larger ones of the Himalayan Hazel (Corylus 
colurna) both towards the end of May. 
In the middle of August a species of Apoderus was taken 
from teak leaves in Damoh in the Central Provinces, but I am
