957 ( ). ERXOPORUS KANAWH^E Hopkins, 1915-a, 35. 



Oblong, moderately stout. Dark brown. Pronotum slightly broader 

 than long, sides slightly rounded from base to apex, rugosities moderately 

 coarse and not in concentric rows, posterior, dorsal and lateral areas 

 shining, faintly rugose and with four apical teeth. Front short, broad, 

 faintly impressed. Elytra with fine scales and coarser, longer interspacial 

 scales, especially on the declivity; strife obscure, with fine punctures; in- 

 tervals faintly rugose toward base, declivity evenly convex, without evi- 

 dent strife. Length, female, 1.65 mm. 



Kanawha Station, W. A'a.; April 15. Allied to E. schrcineri 

 Eieh., of Europe, living in linden; other European species live in 

 beech. 



YII. TRYPOPIILCEUS Fairmaire, I860. (Gr., "perforate"-)- "bark.") 



Antenna 1 club compressed, elongate-oval, with three nearly 

 straight sutures, distinct on anterior face and obscure or absent 

 on posterior face; eyes short oval, narrowly emarginate. Males 

 not smaller than females. Several species are known in Europe 

 and our western states, and one has been described from Nova 

 Scotia. All attack alders, willows or poplars. The genus is treated 

 as a subgenus of Cri/nJialus by Hagedorn. 



958 ( ). TKYPOPHLOEUS NITIDI*S Swaine, 1912, 349. 



Black, clothed with short, gray hairs of two lengths. Head subglobu- 

 lar, with coarse, very shallow punctures and aciculate behind the eyes, 

 front more coarsely punctured; a median longitudinal impression ending 

 in a V at base of epistoma, which bears a few long yellowish hairs. An- 

 tennal scape strongly curved, clavate; funicle 5-jointed, first joint large, 

 pedunculate, remaining four saucer-shaped, widening rapidly. Pronotum 

 as wide as elytra, base broadly rounded, sides sinuate, strongly convergent 

 in front, apical margin with two larger recurved points on median line, 

 two or three smaller ones each side; asperations of front half strong, con- 

 centrically arranged, posterior half coarsely, densely punctured. Elytra 

 more than twice the length of pronotum, sides parallel to declivity then 

 narrowed to the rounded tip; punctured in rows, striae hardly impressed; 

 interspaces confusedly very finely punctured and with a row of widely 

 separated punctures bearing bristles; pubescence short on disc, longer on 

 sides and declivity. Length 2 mm. 



Weymoutli, Nova Scotia, in dying stems and twigs of AJnus. 

 Closely related to T. alni of Russia.

 As restricted by Hopkins, this genus has a 4- join ted funicle
