320 PR0CEEDIJSIG8 OF THE THIRD ENTOMOLOGICAL MEETING 



Conarilirus jansoni, WoU. In the coastal tracts of Malabar a 

 Cochin I have noted a small shining black beetle boring in numb( 

 into the bamboo framework of sheds and fences near houses. The sp 

 bamboo pieces are badly tunneled in some cases. Fletcher has noted 

 beetle of similar habits in Ceylon {Myocalandra exarata, Boh.), bu1 

 find that this insect is not the same as the Ceylonese one. 



The Jak-fruit weevil (PI. 12, f. 1). In Malabar and the Mysc 

 uplands voung fruits of jak trees are sometimes very badly damag 

 by this insect. The weevil is a very small one. measuring abo 

 6 mm. in length, and is pale-greyish-brown in colour. The snout 

 prominent. Hundreds of the small cream-white grubs are fou 

 riddling healthy tender fruits and as a consequence the fruits shri^ 

 up and drop down. Dr. Marshall, to whom I sent specimens soi 

 time back, tells me that the insect belongs probably to a new ger 

 and that he would describe the same soon. 



Calandra rugicollis, Fst. This small weevil has been noted as 

 pest of sal {Shorea robusta) seedlings in Ganjam. In appearance it 

 more or less like the ordinary rice Calandra but slightly bigger. . 

 fallen sal seeds contain the grubs and pupae of this weevil. This \\ 

 noted by a nephew of mine who is a Forest Officer. It appears clos( 

 aUied to the acorn weevil {C. scidpturata, Gyll.) mentioned by St( 

 bing, and is perhaps the same as the undermined ' Sal weev 

 referred to by Stebbing on page 450 of his book on Indian Forest Insec 



Eubber Scolytid.* (PI. 12, f. 2^. A small reddish-brown Scolyi 

 beetle (very hkely a species of Xylebonis) was recently sent up fr( 

 a rubber estate in Cochin as doing damage to Hevea bark. 



Eubber Platypodid. (PI. 12, f. 3). This was reported from Trav£ 

 core doing the same kind of damage to rubber bark. The insect fr( 

 its structure appears to be a species of Platypodid. 



Coconut Scolytid. A small Scolytid, said to damage coconut sten 

 has been received two or three times from different parts of South Ind 



The real bionomics of these Scolytids have to be studied to see whetl 

 they are the cause or the effect in these different cases, since in the a 

 of rubber a fungus disease is often found mixed up. 



Two weevils — Melon weevil [Acytlwpeus citnilli, Marsh) and a sm 

 Apion {Ainon amplum, Fst.) may also be added to the list of weevils, T 

 former was noted in Cuddapah and Bellary inside melons, and the latl 

 has been collected on Anacardium fruits in Malabar and also breedi 

 in green-gram pods in Coimbatore. 



* Since named by Col. Winn Sampson as Xyleborus biporus, n. sp.
