bands on the dark elytra, which are of a hghter shade before the 



middle. 



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

 \'irL;inia the latter part of June, by Dr Hopkins, who 

 records this species as a borer in spruce bark. Mr 

 Young has known of this insect emerging from spruce 

 siding after it had been manufactured, and Dr Hamil- 

 ton lists it as occasional in southwestern Pennsylvania, 

 stating that the larva is probably imported in lumber. 



Distribution. This insect is probably widely dis- 

 tributed in the northeastern United States, since it has 

 been recorded from West Virginia, New Jersey, Staten 

 Island and Buffalo N. Y., besides being occasionally found 

 in southwestern Pennsylvania.

Lcpf/ira canadi-iisis P^abr. 



A large, handsome, black lieetle with the bas;il portion of the black wing cases deep 

 red and the middle antennal joints broadly ringed with reddish, works as a footless grub 

 under spruce and hemlock bark. 



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

 Hopkins, the stout, tfesh)-, round-headed grubs mine the sapwood of dead 

 spruce and hemlock, inducing rapid decay. We have met with what we 

 believe to be this larva working in live hemlock tissues, though this habit 

 may be somewhat exceptional. The adult beetle is a handsome insect 

 about ^ 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.
