A stout, brownish bark beetle about 3/,6 inch in iengtli, may be found workinj; 

 under pine bark during early spring and again in Se|)tember. 



A sin_i:^le example of this species was taken 1))- us at IJath-on-l ludson, 

 Sep. 26, 1 901, from imder tlie moist bark of a hard pine infestecl with 

 Rhai,MiMn li neat urn Kirhy. The tree had evidently been killed by 

 borers, and it is probable that tliis species had a i)art in tht: destructive 



work. 



Description. This brownisli black beetle is about 3 15 inch in length. 

 The labrum bears a few golden yellow hairs at its lower extremity ; the 

 l)rothoraN is rounded at the sides, narrowed anteriorly, and 

 thickly and somewhat coarsely punctured. The wing 

 covers are deeply striated, the striae being almost a series 

 of confluent punctures. The posterior third of the elytra 

 is sparsely clothed with rather coarse, yellowish hairs. 

 The larva is a footless, curved, white grub, according to 

 Packard.

by Dr 1-itch, who records it as occurring fre([uently on pine largcj (..riRinaM 

 lumber in mill )ards early in Ma\-, and who characterized it as the pine 

 destroying llvlastes. Dr Packard has recorded finding tiie beetles imder 

 the bark of a white pine stump at Brunswick Me., Aug. 15-20, 1881. This 

 species has been met with by 1 )r llopkins of West Virginia, who states 

 that it mines the green bark of pines, l)oth at the base of thing trees and 

 also in logs and stumps. lie states that the adults were met with in early 

 May (some entering the bark on tlie i8th), and the latter part of June, 

 pupae occurring Oct. 4. Eggs were observed in early Ma\-, young larvae 

 June 13, and full grown ones July 14. 



Distribution. This species has been recorded by Dr LeConte. from
