Life History. in Jaunsar in the middle of June. Setems indosinica, 



The beetles were either just ma- Fairm. N.W. Himalaya, 

 turing in the trees or were pairing beneath the bark. 



Beetles were taken from both sound timber and trees which had been 

 dead for several years. They were also found in large stumps of trees 

 of this pine. 



I observed a pair of the beetles in coitn on 19 May 1902, under the 

 thick lower bark of a girdled nearly dead blue pine, and kept the pair under 

 observation for several days. The eggs are laid on the sapwood, and the 

 grubs feed here, tunnelling down into the wood to pupate. I took no pupae 

 in this tree, but found the pupal chambers at some distance down m the 



wood. . • u 4- 



The beetles are very shv insects, and if alarmed will remain without 



movement for a long period of time. They dislike daylight, and at once 



make for a shadow or dark corner if exposed to it. 



The beetles have under-wings, and the elytra are not soldered together.
