826 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



street, Brunswick, ou laud from which timber was felled, as we were 

 informed, in November, 1880, so that the period duriug which the in- 

 sects*had been at work was known quite exactly. 



Fig. 219.—Crypturgug atornus. 



This species has been kindly identified for us by Dr. John L. Le 

 Conte, of Philadelphia, who has also prepared the following descrip- 

 tion, which is much more complete than the original description in the 

 Transactions of the American Entomological Society. (Vol. II.) 



This beetle is said by Eichhoff (Eur. Borkenkafer, 166) to be a syno- 

 nym of Crypturgus pusillus Gyllenhal. 



The beetle. — Slender, dark, piceous, shining, prothorax distinctly longer than wide, 

 sparsely and coarsely punctured ; elytra very finely not densely pubesceut, striae com- 

 posed of shallow punctures, interspaces as well as the striae without distinct punctu- 

 lations. Length, 1""" +, 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 

 cylindrical, 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 impercep- 

 tibly punctulate. Beneath nearly smooth, sides of metasteruum with a row of punc- 

 tures, 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. 



4. The pine-timber beetle. 

 Piiyophthorua materarius (Fitch). 



This bark-borer has been noticed ou p. 718. We found numbers of 

 them at Brunswick in August, 1881, which were identified as such by 

 Dr. Horn, under the bark of a spruce, which had been cut down the 

 preceding November ; a few larvae occurred with these. 



5. Hylurgops pinif ex Fitch. 



This species, noticed on p. 722, as occurring in pine stumps, was also 

 found mining under the bark of spruce stumps of trees felled in No-
