PROCEEDINGS OF THE THIRD EXTOMOLOGICAL MEETING 121 



Usually not very serious but a major pest of cane at Sindewahi, Central 

 Provinces. Apparently unknown in Bombay, Our specimens are from 

 Cawnpur, Saran, Chapra, Dumraon, Pusa, Sindewahi, and Hagari 

 (Madras). 



Control methods include prompt cutting out of dead-hearts and collec- 

 tion of egg- masses. In the Central Provinces early planting of setts 

 in October-November, instead of in February-March, has been found 

 effective in mitigating attack. 



Scir-pophaga monosfigma, Z. 



S. 1. 1., p. 426, f . 30.3 ; Proc. Second Entl. Meeting, p. 144. 



Widely distributed in the Plains and is occasionally a minor pest of 

 sugarcane but not common as a rule. Our specimens are from Pusa 

 and Saran in Bihar. 



Scirpophaga gilviberbis, Z. 



Hmpsn., F. I., IV, 46 ; Proc. Second Entl. Meeting, p. 174. 



Found very commonly in paddy areas in Lower Burma where it 

 will probably prove to be a specific pest of paddy. 

 Specimens also from Pusa, Bengal and Assam. 



Schccnohius immeri talis, Wlk. 



Hmpsn., F. I., lY, 47 ; Proc. Second Entl. Meeting, p. 174. 



Reared at Trivandrum, Travancore, from larvse boring in rice-plants. 

 Tliis species does not seem to have been bred otherwise. It is widely 

 distributed and may prove to be a minor pest of paddy. 



Schcenobius bipunctifer, Wlk. 



S. I. I., pp. 426-427, t. 29 ; Proc. Second Entl. Meeting, pp. 171-174. 



Occurs throughout India, Burma and Ceylon as a major pest of paddy, 

 the larva boring in the stem. 



This is the most important insect pest of paddy in India and Burma, 

 usually destroying about ten per cent, of the total crop and doing damage 

 totalling hundreds of millions of rupees annually. The female moths 

 are attracted to light in large numbers but systematic trials of Hght- 

 traps have shown the inefficacy of this method as a means of control. 

 The hand-picking of egg-masses and first attacked shoots is not practi- 

 cable on a large scale over extensive areas, and hardly feasible in small 

 plots. In districts where this can be done the growing of pulses or
