430 CHRAMESUS ? sp. 

beginning of July I was able to inspecta felled dead oak which 
had been attacked by the May beetles the preceding year. 
At the time of attack the tree was girdled-but still alive. The 
July inspection failed to show any live beetles in the tree or any 
larvee or pupe, and I concluded the wood was then too dry for 
the insect. An inspection of old holes and tunnels showed that 
most of them contained a dead beetle at their mouths, From 
this I infer that the beetles after egg-laying and protecting the 
larve go back to the mouth of the tunnel and die there when 
the grubs pupate, thus effectually blocking it up against the 
entrance of predaceous insects. This insect probably belongs 
to the class of beetles known as “ambrosia” beetles, the larve 
feeding not on wood but on a kind of fungus growing in the 
walls of the beetle’s tunnel. 
Locality from where reported. 
This beetie was discovered by the writer at Kathian in the 
Jaunsar Barwar Forests, N.-W. Himalayas, 
Relations to the Forest, ete. 
This insect is a wood-borer and is capable of drilling 
beautifully circular holes through hard oak timber. Beyond 
this and the fact that it flies about in swarms, when on the wing, 
which settle close together on dan oak trees and riddle the 
timber by closely placed galleries, little is known about its 
action in the forest. 
Points in the lifeshistory requiring further observatton, 
1. How the larvz feed and length of time spent in this 
stage, 
2. Length of time spent in the pupal and beetle stages. 
3- Number of generations in the year. 
4. Is the insect abundant ?
