120 MISCELLANEOUS FOREST INSECTS. 



Length, 3.5 to 4.5 mm.; fenuginous. Pronotum .^liiiiy, rather densely, Init not at 

 all scabrous or rugosely punctured, the punctures smaller and less dense ante- 

 riorly; median impression broadly oval, deep, not approaching anterior margin; 

 anterior margin broadly rounded, sides parallel, straight or faintly sinuate; 

 anterior angles obtusely rounded; posterior angles right, prominent, not at all 

 or very feebly rounded. Elytra broad, distinctly narrowed toward base, more 

 strongly convex at about their middle; interspaces not at all elevated; punctures 

 very fine, elongate, seriate as in opaculus; pubescence of medium length, fine, 

 decumbent, strongly seriate in arrangement. Plead with front strongly convex, 

 smooth, shiny, evenly but not densely punctured; epistoma depressed, its 

 anterior margin broadly emarginate, the anterior angles elevated and with coarse 

 pubescence; antennae very slender, the club weak, narrowly oval. Abdomen 

 feebly shiny below, exceedingly finely, densely punctured.

Section a4- 



Length, 2.5 to 5.5 mm.; black. Pronotum shiny, rather densely ])ut not at all 

 rugosely punctured, median impression broad, shallow, narrow from posterior 

 margin to middle, where it becomes broadly, gradually expanded to the anterior 

 margin, rarely deep, suboval and scarcely expanded anteriorly; anterior margin 

 broadly rounded; side margins strongly arcuate and convergent posteriorly 

 or nearly straight and subparallel; anterior angles broadly rounded, not at all 

 prominent, posterior obtuse and feebly rounded or subrectangular and sharp. 

 Elytra elongate, convergent toward base, the interspaces flat or just visibly con- 

 vex; punctures very fine, seriate as in opandus; pubescence fine, sparse, decum- 

 bent, distinctly seriate. Head with front strongly convex, densely, subrugosely 

 punctured; epistoma depressed, anterior margin broadly emarginate, anterior 

 angles not elevated; antenna stout, clu1i prominent; abdomen shiny below, 



densely, finely 'Jiunctured planicollis Le Conte, pages 124-125. 



Length, 2.4 to 4.7 mm.; black. Pronotum opaque, punctato-scabrous; median 

 impression reduced to a shallow, narrow line from anterior to posterior margin; 

 anterior margin very strongly, broadly arcuate; side margins strongly curved 

 and convergent posteriorly; anterior angles very broadly, obtusely rounded; 

 posterior angles obtuse, not rounded. Elytra narrowed toward base; interspaces 

 .noticeably convex; punctures coarse, narrow, elongate, deep, seriate; pubescence 

 fine, sparse, seriate. Head with front strongly convex, scabrous; epistoma small, 

 depressed; anterior margin broadly emarginate; antennse slender, club strong, 

 compact, (jval. Abdomen subopaque below, very densely, finely punctured.

Subdivision D. 



Length 2.5 to 5 mm.; ferruginous. Pronotum opaque; surface very finely granulate 

 and pubescent; median impression oval, deep, extending from anterior fourth 

 to posterior fourth and thence very narrowly to posterior margin; anterior margin 

 strongly arcuate, sides straight or feel)ly sinuate, not at all or but scarcely nar- 

 rowed Ix'hind; anterior angles obtuse, broadly rounded; posterior angles right, 

 not at all rounded. Elytra just visi))ly narrowed toward liase; interspaces flat; 

 punctures shallow, circular, arranged in single series except at costal border, where 

 they are in double series; pubescence sparse, fine, decidedly seriate in arrange- 

 ment. Head with front strongly convex, side margins distinctly elevated over 

 the eye, densely, finely granulato-punctate; epistoma narrow, its anterior margin 

 broadly, deeply emarginate; anterior angles not elevated; antennaj slender, 

 noticeably pul)escent, club large and prominent. Abdomen feebly shiny below, 

 densely, fin(>ly punctate linearis Goeze, pages 125-126.
