320 PROCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 



ConartJirus jansoni, WoU. In the coastal tracts of Malabar and 

 Cocliiii I have noted a small shining black beetle boring in numbers 

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

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

 beetle of similar habits in Ceylon [Myocalandra exarata, Boh.), but I 

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



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

 uplands young fruits of jak trees are sometimes very badly damaged 

 by this insect. The weevil is a veiy small one, measuring about 

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

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

 riddUng healthy tender fruits and as a consequence the fruits shrivel 

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

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

 and that he would describe the same soon. 



Cahmlra rugicoUis, Fst. This small weevil has been noted as a 

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

 more or less like the ordinary rice Calandra but shghtly bigger. All 

 fallen sal seeds contain the grubs and pupse of this weevil. This was 

 noted by a nephew of mine who iS a Forest Officer. It appears closely 

 allied to the acorn weevil (C. sculpturata, Gyll.) mentioned by Steb- 

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

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



Rubber Scolytid.* (PI. 12, f. 2). A smaU reddish-brown Scolytid 

 beetle (very hkely a species of Xijlehonis) was recently sent up from 

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



Rubber Platypodid. (PI. 12, f. 3). This was reported from Travan- 

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

 its structure appears to be a species of Platypodid. 



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

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



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

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

 of rubber a fungus disease is often found mixed up. 



Two weevils — Melon weevil {Acythopeus citndli, Marsh) and a small 

 Apion [Afion ampluni, Fst.) may also be added to the list of weevils. The 

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

 has been collected on Anamrdium fruits in Malabar and also breeding 

 in green-gram pods in Coimbatore.
