 stamping out the attack.

Beetle. A large brown weevil, the male with very long anterior legs. 



This beetle was reported by Mr. C. G. Rogers as infesting the 



hill bamboo in the Darjeeling forests. Mr. Rogers 



Life History. noted that the insect attacked the asparagus-like 



tops of the bamboo, and that the beetle is often seen 



clinging to the shoots, which are found to be perforated by a hole from which 

 it has emerged. 



The egg is apparently laid on or in the shoot, and the grub feeds inside 

 in a manner similar to that of C. longibcs in the muli bamboo in the Chitta- 

 gong Hill Tracts already described.

Cyrtotrachelus ? sp. 



Habitat. Tharrawaddy, Lower Burma. 



Tree Attacked. bamboo (Ccphalostachyiun pergracile), Tharrawaddy. 



Beetle. Unknown. 



During a tour in the Tharrawaddy Division of Lower Burma, in January 

 1905, I noticed that the young shoots of the Ccphalo- 



Life History. stachyuin pergracile bamboo, which were plentiful in the 

 forest, had in many cases been tunnelled into by an 



insect whose operations closely resembled those of Cyrtotrachelus lon^ifics in 

 the Melocanna bamboo in the Chittagong Hill Tracts described above. 



Shoots of 3 ft. to 4 ft. in height are attacked and killed by the insect, and 

 may be found standing upright and dead in the forest, a large round hole at 

 one side showing where the imago had left the bamboo when mature. In- 

 side the upper portion of the bamboo is entirely hollow, the interior hiving 

 been eaten away. 



The local native forest officials and villagers appeared to be well 

 acquainted with the insect infesting this bamboo, the tunnelling work inside 

 being done by a large yellowish-vvhite grub. In the rains the people are said 

 to search in the shoots for this grub and to eat it with relish, a habit common, 

 I believe, to the inhabitants of the Chittagong Hill Tracts in the case of the 

 C. longipes grubs. 



I think there is every probability that this larva, which unfortunately I 

 have not yet been able to procure, will prove to be a weevil one, and it is
