Life-FHistory, 
The mature beetle is to be found boring into fresh deodar 
wood towards the end of June at elevations of about 7,000 feet, 
It bores down through the bark either straight or at an angle until 
it reaches the outer sapwood and then goes horizontally down 
into this for some distance, the tunnel curving towards its lower 
end where the eggs are laid. As yet it has only been found in 
fresh newly-felled deodar trees whose bark is still full of sap. 
In these the beetle burrows into the wood indiscriminately both 
at the thickest end of the tree (where the diameter was 3 feet 
across) and equally into the top and larger branches, The burrows 
made are cylindrical. I have not yet found the larve, and do not 
know whether the beetle frequents dry woud. The insect has 
the curious habit of moving up and down its tunnel, it 
being often found in the portion of the tunnel in the bark,
