It damages cotton in the same way as A. leopardus. It is distinctly 

 a pest of Hibiscus cannabinus but not a serious pest of cotton. 

 At Palur and Saidapet tree-cottons were attacked.

This species occurs at Dacca in July as a decided pest of mango, 

 the larva boring the top-shoots. Eggs are deposited in the shoots which 

 are tunnelled by the larva, whose pellets of excrement are thrown out 

 through small holes gnawed at the base of the tunnel. Pupation takes 

 place inside the larval burrow, the adult weevil gnawing its way out 

 through a large hole of exit. The adult weevils are found freely pairing 

 and ovipositing on the shoots. 



It is a regular pest of grafted mangoes in the Botanical Garden at 

 Dacca. It occurs every year and does much damage. The eggs and 

 grubs are very commonly to be seen in the affected shoots. 



Can you give us some idea of the percentage of damage ? 



As many as seventy-five per cent, of new shoots are damaged. 

 . Have you tried picking off the affected shoots ? 



We have tried picking the affected shoots with the eggs and grubs 

 in them and also the beetles which are seen on the shoots. 



Were any effects noticeable the next year ? 



Next year it was not so bad. 



It is possible to pick off the affected shoots, but the influence of picking 

 on future years is not definitely known. 



Do you know its life-history throughout the year ? 



I have not studied it. 



The seasonal life-history is not known. At Pusa we had pupae in 

 September. The beetles are only seen in July. 



Probably it hibernates as an adult until the new shoots come out.* 



Alcides mali, Mshll. MS.* 



This species has been found at Shillong, the larva boring shoots of 

 apple, causing a gall-like swelling. The adult weevil makes several, 

 usually four, holes with its snout in a row in a tender shoot of apple and 

 in one of these holes, and only in one, it deposits an egg. The larvae 

 tunnel in the stem, which becomes swollen in consequence. Pupation 

 takes place in the larval tunnel. The life-history is sho^vn on the coloured 

 plate [exhibited]. Control is practised by collecting the adult beetles as 



Since described in Bull. Entom Res. IX, pp. 276-277, t. 17 f. 3 (July 1919).
