Indian Museum Notes. 



[Vol. VI. 



Some time ago* I showed that the supposed fact of the disappear- 

 ance was not real, and that the insect could be found on the bushes 

 in all stages at any part of the year, provided sufficient care were 

 taken in seeking them. I also showed that living eggs were present 

 in the bushes in January when the insect was supposed to be in full 

 hibernation. During the past hibernating season I have been able, 

 with the aid of Mr. J. J. Smith of the Behalli Tea Estate, 

 Assam, to follow the life of the insects throughout the hibernating 

 period. On nearly every day since December 25, 1902, to the end 

 of April, boys have been employed catching the insects, a task, at 

 which, though it is of extreme difficulty to a beginner, they become 

 very expert. More than this, every day's catch has been sorted out 

 into males, females, and larvae. The results summarised are as 

 follows :— -

The above plots were sprayed with kerosene emulsion (see below) 

 in January, February, and March. On another garden, close to the 

 above, where the place had been partly, but only partly, sprayed 

 with Chiswick Compound the following figures were obtained in 

 March and April : —
