Life History, 



The fact that this 

 insect lives in green 

 oak-trees in the 

 Southern Shan States, 

 at about 5,000 ft. ele- 

 vation, was discovered by Mr. H. W. A. Watson, 

 I.F.S., the Divisional Forest Officer, in 1907, and all 

 that is at present known of the life history of the in- 

 sect is due to his careful and untiring investigations. 

 His observations, which he considers require further 

 careful verification, are as follows : — 



" Fertilization takes place apparently in 

 the tunnels. One 2 of those sent contained 

 about fifty large eggs.
