Pine Hylurgops 

 Hylurgops glahratus Zett. 



A stout, brownisli hark beetle aliout y,6 in< :li in length, may be found working 

 iinder pine bark during early spring and again in SejHember. 



A single example of this species was taken by us at Batii-on-1 liidson, 

 Sep. 26, igoi, from under the moist hark of a iiard pine infestetl with 

 Rhagiiim lineatum Kirby. The tree had evidently been killed by 

 borers, and it is probable that this species had a part in the destructive 

 work. 



Description. This brownish black beetle is about 3',f, inch in length. 

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

 prothorax 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. 



Life history and habits. This borer was first noticed f'l 

 by Dr Fitch, who records it as occurring frequently on pine i..ri;ed (original 

 lumber in mill yards early in May, and who characterized it as the pine 

 destroying Hylastes. Dr Packard has recorded tinding the beetles under 

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

 species has been met with by Dr Hopkins of West Virginia, who states 

 that it mines the green bark of pines, both at the base of dying trees and 

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

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

 pupae occurring Oct. 4. Eggs were observed in early May, young larvae 

 June 13, and full grown ones July 14. 



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