NEW AMERICAN SCOLYTOID BEETLES — BLACKMAN 373 



Pronotum 1.13 times as long as wide, widest near middle; posterior 

 outline bisinuate, posterior lateral margins scarcely rounded; sides 

 nearly straight and subparallel on more than posterior half, very 

 broadly rounded in front; surface moderately shining, finely, closely 

 punctate-strigate, median line lacking; hairs stout at sides and near 

 front, nearly lacking on disk. 



Elytra wider than pronotum and 1.61 times as long, 1.65 times as 

 long as wide ; sides subparallel on anterior two-thirds, broadly rounded 

 behind; surface shining; striae deep, moderately narrow, punctures 

 small, indistinct; interspaces much wider than striae, reticulate, finely 

 punctured, bearing rather numerous short, appressed hairs, with sparse 

 uniseriate rows of small granules, with suberect bristle arising from 

 base of each. Declivity sloping, broadly and shallowly sulcate in 

 sutural area; interspaces narrower and more. convex than on disk, 

 uniseriately granulate, with erect bristles more numerous than on 

 disk.

CNESINUS COGNATUS, new species 



PiLATE 15, Figure 6 



Dark reddish brown; 2.2 mm. long, 2.48 times as long as wide; 

 rather closely related to sfrigicollis LeConte, but notably smaller and 

 differing in the character and arrangement of the vestiture. 



Frons (fig. 6) piceous-brown, subopaque, convex above between the 

 moderately approximated eyes, bordered below by a transverse carina, 

 with portion ventral to it broadly transversely impressed ; punctures 

 fine and close below and at sides, with cinereous, moderately long, 

 stout hairs, those from sides directed dorsomesad. Eye relatively 

 smaller and more elongate oval than in strigicoUis, facets notably 

 finer, inner line very broadly and shallowly emarginate. 



Pronotum 1.05 times as wide as long, widest at middle, posterior 

 outline slightly bisinuate, posterior lateral angles rounded; sides 

 nearly straight and feebly diverging on posterior half, very broadly 

 rounded in front ; surface moderately shining, finely, closely punctate- 

 strigate, median line lacking; vestiture of stout, subsquamose hairs 

 at base, sides, and apex, fine, short, and inconspicuous on disk. 



Elytra slightly wider than pronotum and 1.75 times as long, 1.61 

 times as long as wide ; sides subparallel on anterior two-thirds, mod- 

 erately narrowly rounded behind (not so broadly rounded as in strigi- 

 collis) ; surface shining through the rather abundant vestiture ; striae
