FAMILY CURCULIONIDAE 



case with the sissu Apodcnis. The weevil makes two curved cuts 

 below the apex of the leaf, until they meet the midrib about a third 



down from the apex, as shown in the 

 sketch, and the portion between the 

 cuts is then rolled up after an egg has 

 been deposited near the apex (A). An- 

 other method of operation is to cut 

 out a portion from the side of the leaf 

 and roll this up along one of the side 

 veins, D E and n F. 



In addition to making use of the 

 leaf in this manner for ovipositing pur- 

 poses, the weevil also feeds upon it, 

 eating out small patches of the paren- 

 chyma, as shown at B in the figure.

This weevil was found plentifully in the 

 forests round Mount Stuart, in South Coim- 

 batore, towards the end of 



Life History. July IQO2. The beetle was 

 feeding on the leaves of 



teak, and feeding and ovipositing on those of // 

 Hclictcrcs. The teak-leaves had their edges 

 cut and slit up under the attacks. The soft 

 pubescent leaves of the Hclictcrcs were skele- 

 tonized, the parenchyma of the leaf being eaten 

 out, leaving a rough lace-work. Other leaves 

 had portions eaten out of the edges, or patches 

 eaten out of the interior, the veins being eaten 

 as well as the parenchvma, as shown in the 

 figure. This latter was the common method of 

 attack in the case of the teak-leaves.
