In company with Mr. W. F. Perree, I took specimens of the larva, 

 pupa, and beetle of this insect in the rotten wood

May, at Kachugaon, in Goalpara. The larvae were 

 apparently predaceous, feeding upon one or more of the numerous wood- 

 boring insects present in the tree. To pupate, the grubs eat out small 

 elontiaie chambers in the wood.
