 North and Widdle Europe. In Denmark rare or very rare, and hereto- 

 fore apparently found only in pinaceous woods here and there in Xorth 

 Sjaelland (Rudehegn, St. Dyrehave at Killer^d, Tisvilde Hegn and other 



places). (Page 433) 



It lives and developes under the bark of pinaceous trees, which are 

 attacked by bark-beetles. In July I have found larvae and pupae,. ear- 

 lier, and later beetles. The larva is yellowish white with reddish- 

 brown head and pronotum and its form shows relationship with imago 

 (see further J. G. Schi,c/dte Nat. Tidsskr. 3. P.. 3.B. 1364, 65, 201 

 lab. IX and X) . It is very agile and flits swiftly, with forward and 

 backwards subtle motions, about in the burrows.
