PROCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 207 



Cyrtoirachelus dux, Boh. 



Stebbing, Ind. Forest Ins. Col., p. 443 ; Proc. Second Entl. 

 Meeting, p. 204. 



We have this from Nongpoh (Khasi Hills). Stebbing records it from 

 Darjiling. The larva bores in bamboo shoots and does some damage 

 at times. 



Cyrtotrachelus longii^s, Fb. 



Stebbing. Ind. Forest Ins. Col, pp. 440-443, t. 38 ; Proc. Second 

 Entl. Meeting, p. 204. 



We have this from Lebong (Darjiling). As in the case of C. dux, 

 the larva of C. longipes bores in the growing shoots of bamboos and does 

 some damage at times. 



Poly t us mellerborgii. Boh. 



We have this from Pusa where it was reared from rotten plantain 

 rhizome and found '' boring plantain root, 9th May 1907." We do not 

 know this as a pest in India as yet, but in the Philippines it has been 

 found to do damage by boring into plantains and it is probable that it 

 is a pest in India also. The adult is a small black weevil, about the 

 size of Calandra oryzce, with a strongly punctured thorax and striated • 

 elytra , 



Rhyncho'phorus ferrugineus, Fb. 



S. 1. 1., p. 343, t. 14 ; Entl. Mem. 11, pt. 10 ; Proc. Second Entl. 

 Meeting, pp. 259, 261, 262. 



This species occurs throughout the palm-growing districts of India, 

 and also in Sumatra, the Philippines, etc. In India it attacks coconut, 

 date, palmyra, areca and practically all palms. We discussed this fairly 

 fully at the last Meeting and I do not think there is much to add. It 

 can be controlled by regular destruction of all attacked, dying and 

 dead palm-trees. 



I have found Rhyncho'phorus ferrugineus attacking trees which bad Mr. Pillay. 

 neither been tapped nor attacked by Orycfes. 



It does serious damage to date palms in Surat. Mr. Jhaveri. 



Do the weevils vary in colour ? Mr. Ramrac. 



Yes, the colour and markings vary considerably. Mr. Fletcher, 



Palms are also attacked in Ceylon. Mr. Senior-White.
