Life history and habits. The beetles have been met with in West 

 X'irginia the latter part of June, b\- Dr Hopkins, who 

 records this species as a Ijorer in s])ruce bark. Mr 

 \'oung' has known of this insect emerging from sjjrnce 

 siding after it had been mannfactured, and Dr Hamil- 

 ton lists it as occasional in southwestern Penns\-lvania, 

 stating that the larx'a is ]jrobably ini[)orted in lumber.

Canadian Leptura 



Lcptiira canadensis habr. 



A large, handsome, black l)ectle with the- l>asal portion of the l)lack wing cases deep 

 red and the middle antennal joints l)roadlv ringed witli reddish, works as a footless grub 

 under spruce and hemlock hark. 



This species is more or less common in hemlock, and according to Dr 

 Hopkins, the stout, flesh}', roimd-headed grubs mine the sapwood of dead 

 spruce and hemlock, inducing rapid deca)-. We have met with what we 

 belie\e to be this lar\a working in li\'e hemlock tissues, though this habit 

 may be somewhat e.xceptional. The adidt beetle is a handsome insect 

 about -){j^ inch in length, deep black, with the surface coarsely and densely 

 punctured. It may be readily distinguished from its allies by the deep red 

 basal portions of the wing covers and also by the antennae being broadly 

 ringed with paler red, the joints of the middle being alternately red and 

 black. The beetle may be met with in July and is rather common in the 

 Adirondack region.
