180 HALTICIDES. 
At other times all the leaflets disappear entirely. The beetle 
begins by eating the leaflet irregularly round the edge, 
patches being gnawed out, or it commences on the inner part 
and eats out holes in the leaf tissue. The effect of this 
defoliation is to cause the leaflets to shrivel up, turn brown 
and fall off. 
At the beginning of August, when these beetles were 
observed at work, the insects were pairing; the male, the smaller 
insect of the two, being carried about on the back of the 
female. This Chrysomelid is a powerful jumper, and even 
when coupled the ? will often take along leap. Like many 
Chrysomelide they are extremely wary and take to flight at 
the slightest motion which alarms them. If too late to fly, 
they drop off the food-plant like a stone and sham death on 
the ground, where, owing to a similitude in colouring, they are 
extremely difficult to see. When eae they appear to lose 
some of their extreme wariness. 
At present I have no further observations on the life his- 
tory of this pest. 
Locality from where reported. 
This insect was found in the Bhamburda Reserve near 
Poona in the Bombay Presidency, 
Relations to the Forest. 
I have described above the manner of feeding of this 
Chrysomelid. There can be no doubt that when in any numbers 
itis capable of doing a large amount of defoliating damage. 
We do not yet know where its larval stage is passed or upon 
what the grub feeds. 
Protection and Remedies. 
When feasible in nurseries and young plantations, ‘this 
beetle can be attacked in its adult stage by means of the Paris 
green arsenic treatment described on pages 146—149 of these 
notes (No.1). The beetle, being a leaf-feeder, will take the 
poison internally and be killed off. We require to know more
