PROCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 



Mr. Misra. 



Mr. Fletcher. 



Four or five feet. The majority of the plants all fell down. In our 

 experiments it was very bad, so much so that in one plot not a single 

 plant was left. 



Adees cribratus, Gyl. 



This was found at Shillong in June-July 1918, the larva boring into 

 the main stem of Ficus carica, doing considerable damage. 



The adult beetles occurred on the stems by day, and could be collected 

 by hand, although they readily drop to the ground when disturbed. 



Specimens were sent to Dr. Marshall who informs me that it is a 

 variety of Adees cribratus, Gyl. 



Cryptorrhyndius mangifercB, Fb. 



S. I. I., p. 341, f. 200 ; Proc. Second Entl. Meeting, p. 225. 



This species seems to be confined to Southern India so far as its actual 



, breeding-area is concerned. We have records from Trivandrum, Travan- 



core, Naduvatam (Nilgiris), Coimbatore, Palur (South Arcot), Lahore 



and Rangoon. The Lahore specimen is definitely noted as " in imported 



mango." 



In some years ninety per cent, of the mango-stones may contain this 

 insect in some stage, but the adults usually emerge after the fruit is ripe 

 and so do comparatively little damage. 

 Mr. Kunhi Kannan. At Bangalore I had adult weevils which remained alive in the stones 

 until the following July and they never left the stones. 



Cryptorrhyndius gravis, Fb. 



Ann. Rept., 1917-18, pp. 100-101 ; Proc. Second Entl. Meeting, p. 225. 



Mr. Fletcher. This species seems to be confined to Bengal, Assam and Burma. 



We have specimens from Pusa (on Bombax stem), Dacca, Rangpur, Silchar, 

 and Maymyo. The Pusa record is of a single adult individual which 

 almost certainly came from a mango fruit imported from Bengal, as it 

 is not known to occur naturally in the Pusa district. 



Unlike C. mangijercB, the larva of C. gravis bores in the pulp of the 

 mango fruit so that the fruit is badly damaged and in some districts 

 the damage done may be very serious, a large proportion of the crop 

 being destroyed. We have prepared a coloured plate [exhibited] showing 

 the life-history of this insect but, as it does not occur at Pusa, we have 

 not been able to follow the life-cycle throughout the whole year. It is 

 probable that the insect hibernates as an adult in Bengal, but this requires 

 local investigation.
