142 PROCEEDINGS OF THE THIUD ENTOMOLOGICAL MEETING 



" Arbela " iheivora, Hrnpsn. 

 Hmpsn., B. J. XX, 97, t. G. f. 1. 

 Occurs in Assam. The " larva bores in the bark of tea and the smaller 

 branches of mango, feeding under a web." 



CossiD^. 



Cossus cadamhcB, Mo. 



Hmpsn., F. I., I, 306, f. 209. 



Described from Calcutta. Fairly common in Bihar, the larva boring 



in stems of Ficus spp. (? and mango), usually in old trees and probably 



doing little damage. 



Duomitus cemmicus, Wlk. 

 Hmpsn., F. I., I, 307. 

 Said to attack Fig trees of many species in Western India (B. J. 

 XXIII, 765), but this is probably an error for leuconotus. Stebbing 

 (Indian Forest Insects, Coleoptera, p. 14) says that the larva feeds on the 

 bast of teak, tunnelling into the wood to pupate and thus ruining it for 

 timber purposes. 



We have no specimens in the Pusa Collection, and it is probably 

 confined to Burma. 



Duomitus leuconotus, Wlk. 



Hmpsn., F. I., I, 308, f. 219. 



Recorded from Simla, Sikkim, Calcutta and Ceylon. We have this 



from Belgaum and Belgachia. The larva bores in various trees and may 



do considerable damage. It was found boring Cassia fistula at Rangoon. 



Duomitus mineus, Cram. 

 Hmpsn., F. I., I, 309. 

 Widely distributed in India and recorded from Sikkim, Sylhet, Calcutta 

 andGanjam. We have moths from Pusa and Chapra, in North Bihar, but 

 this insect does not seem to be common. The larva does not appear to 

 have been noted but will probably turn out to be a pest owing to its 

 large size. 



[Duomitus sp. 

 We have a caterpillar of a species of Duomitus which damages the 

 main stem of Cassia in the Nilgiris.]
