260 FAMILY CHRYSOMELIDAE 



plantation on 5 April. Two days later I found a tree almost entirely 

 defoliated by the beetles, who were in hundreds upon it. Hard by two 

 other trees had been completely stripped. Some of the beetles were coupling. 

 I could find no larvae on the trees. 



The fact that the beetle appears in the adult stage as early as the first 

 week in April in Assam points to the possibility of there being two broods 

 of the insect in the year in the hot and damper parts of its habitat. 



This chrysomelid must be looked upon as a dangerous defoliating pest 

 in the forest, and more especially in areas of young 

 Vorest growth. The insect (both grub and beetle) is of con- 



siderable size and coarse, heavy build, and strips the 

 trees of foliage and the green cortex from the younger branches in a ruthless 

 manner which cannot but seriously affect the growth of the plants subjected 

 to the treatment. 



We know that the insect pupates in the soil, and the only possible 



method of combating a serious attack would be to 



Treatment. endeavour to kill off the insects whilst in the cocoon 



in the soil. In the case of serious infestations over 



considerable areas in valuable plantations and forests I should recommend 

 the judicious use of fire as the only effective means of dealing with the 

 insect.

Poona on 2 August 1901. The insect was in company 



with the Haltica ? sp. described below, the latter being by far the more 

 numerous of the two present. A serious amount of defoliation had taken 

 place under the attacks of the beetles.
