then changes to a chrysalis inside it. Moths were reared out of 

 infected stems sent to the Museum and proved to be Chilo simplex, 

 the well-known sugar-borer. We thus have another authentic case 

 of this insect attacking juar, and it is evident that cane fields 

 situated in the neighbourhood of juar fields may become infested by 

 the borer from the iatter, and vice versa. 



Cane should not be rotated with juar without allowing the ground 

 to lie fallow for at least one season.

The caterpillars were reported by Mr. H. E. Parrett, C.S., Collector 

 of Dinajpur, as seriously injuring Kalai crops in the Kaliagani Thana 

 of that district in October 1902. Moths were reared in the Museum 

 from caterpillars sent in October 1902. 



Insect infesting Til and Oorid. 



Undetermined caterpillars locally known as " Bhuili," These were 

 reported by Mr. M. C. McAlpin, C.S., Sub-divisional Officer of 

 Bettiah, as causing damage to the young plants in fields of til and 

 oorid. No moths were sent and it has therefore been impossible at 

 present to identify the insect.
