Me., in August 1880, where they occur in dead trees as well as spruce 



stumps, also in white pine stumps. 



The following description of the beetle is given by Dr LeConte : 

 Slender, dark, piceous, shining, prothorax distinctly longer than wide, 

 sparsely and coarsely punctured ; elytra very finely not densely pubescent, 

 striae composed of shallow punctures, interspaces as well as the striae with- 

 out distinct punctulations. Length, 1 mm +. Head with a broad short 

 beak, slightly convex, finely not densely punctulate. Prothorax distinctly 

 longer than wide, slightly rounded on the sides, gradually narrowed from 

 the middle to the tip ; disk transversely convex, not polished, but very 

 imperceptibly granulate, sparsely and strongly punctured. Elytra cylin- 

 drical, not wider than the prothorax, convexly declivous behind ; sparsely 

 clothed with very short and fine yellowish pubescence , striae composed of 

 rather large, shallow punctures, interspaces not narrower than the striae, 

 almost imperceptibly punctulate. Beneath nearly smooth, sides of meta- 

 sternum with a row of punctures, sides of ventral segments feebly punctured. 

 Legs piceous, front tibiae with five distinct acute teeth on the outer edge, 

 which is also sparsely fringed with long yellowish hairs, with a fine apical 

 spine at inner angle ; tarsi yellow, narrow, third joint not dilated. 

 Antennae with the scape long, the first joint of the funicle large, rounded ; 

 second indistinct, closely connected with the club, which is large oval, not 

 pointed, solid, polished and corneous, except along the apical margin, where 

 there is a spongy sensitive band. 



This species probably has a wide distribution in the northeastern 



United States, as it is recorded from Canada and Maine south to West 



Virginia and westward to Ohio.

Large white, fleshy, legless grub from 1% to 2 inches long may frequently wo*rk in 

 the inner bark and sapwood of dead and dying pines, spruces and balsams, and also in logs 

 c ut from these trees. 



This species is one of the more common borers found under the bark 

 of logs and dead and dying trees belonging to the species mentioned above. 

 The presence of the borers in piles of logs may easily be detected by the 

 masses of white sawdustlike borings which collect on the ground beneath 

 or which may be found under the bark. 



Injuries, Grubs belonging presumably to this species have been met
