 out two pupae from their pupal chambers in the sap-

 long axis of the tree, and about half an inch down in 

 the sapwood. From one of these pupae I was able to rear a beetle. 



The pupae were taken on 14 April i<)o6 in the Balipara Keserxe in the 

 Evergreen Forests belt of the Darrang Division. The beetle assumed its 

 full coloration on 2 May following.
