margin to posterior margin. Elytra shiny, subparallel, a little broader than 

 prothorax; punctures large, distinct, deep, circular, strongly seriate, the series 

 impressed; interspaces slightly convex; pubescence fine, sparse, seriate. Head 

 with front convex, opaque, densely, rugosely punctate; epistoma strongly de- 

 pressed, not at all elevated at the sides; antennae stout, the club large, elongate 

 oval pubescens Panzer, page 123. 



DIVISION II. 



Elytral striae composed of a double or sometimes a single row of fine, elongate, deeply 



impressed punctiu-es Subdivision C, pages 119-120. 



Elytral striae each composed of a single row of large, shallow, circular punctures. 



Subdivision D, page 120. 

 Subdivision C. 



Prothorax anteriorly distinctly narrower than the elytra at base. 



Section a3, pages 119-120. 

 Prothorax fully as wide anteriorly as the elytra at their base Section a4, page 120. 



Section aS. 



Pronotum distinctly longer than wide, its anterior angles not at all prominent, very 

 broadly rounded; median impression merely a narrow, faintly impressed groove 

 from anterior to posterior margins; elytral interspaces frequently subconvex, 

 especially toward sides Subsection bl, page 119. 



Pronotum quadrate or subquadrate; anterior angles distinct, sub prominent but not 

 acute; median impression large, broadly oval, deep; elytral interspaces not at 

 all or but feebly convex Subsection b2, pages 119-120. 



Subsection bl. 



Length 2.1 to 4 mm.; castaneous. Pronotum opaque, punctato-scabrous; anterior 

 margin broadly rounded; side margins straight or slightly sinuate and convergent 

 posteriorly; anterior angles subobsolete; posterior sharp, everted. Elytra slightly 

 narrowed toward base; interspaces toward the sides feebly to rather strongly 

 elevated; pimctures coarse, elongate, and in double series between the inter- 

 spaces; pubescence fine, short, dense, decumbent. Head with front strongly 

 convex, densely punctured and granulose; epistoma narrow, depressed, side 

 margins strongly divergent posteriorly, anterior deeply emarginate, its anterior 

 angles not elevated; antennae slender, the club stout, narrowly oval. Abdomen 

 subopaque below, densely, finely, granulately punctured.

 Subsection b2. 



Length 3 to 5 mm.; ferruginous, head and prothorax slightly darker. Pronotum 

 opaque, punctate, scabrous; anterior margin broadly rounded; side margins 

 nearly straight, finely denticulate, acute, parallel or very faintly convergent 

 posteriorly; anterior angles subprominent, obtuse, blunt; posterior angles right, 

 prominent, not rounded; median impression broadly oval, deep. Elytra sub- 

 parallel, scarcely narrower anteriorly, convex but not more noticeably so at 

 their middle; strial punctures very fine, elongate, arranged in single or sometimes 

 in double soi'ies, especially toward sides; pubescence seriate, fine, sparse, decum- 

 bent. Head with front strongly convex, opaque, densely punctato-granulate, 

 sides slightly elevated over the eye; epistoma strongly depressed, narrow, its 

 anterior angles not elevated; antennae stout, the club strong, oval. Abdomen 

 subopaque below, densely, finely punctured. . .swfurafe Faldermann, page 124.
