118 MISCELLANEOUS FOEEST INSECTS. 



posterior obtusely rounded; median impression very broad and shallow; punc- 

 tures coarse, rather dense, sparser and finer anteriorly. Elytra elongate, the 

 punctures small and arranged in distinct series, becoming confused toward suture 

 and base, the pubescence sj)arse and recumbent. Head with front scarcely con- 

 vex, densely, finely punctured; epistoma depressed, side margins strongly 

 reflexed; antennae slender. Abdomen shiny below, densely, exceedingly finely 

 punctured californicus Casey, page 121. 



Series c2. 



Length 2 to 4 mm.; elongate, rather slender, ferruginous to nigro-piceous. Prothorax 

 with side margins strongly convergent posteriorly; anterior margin strongly 

 trisinuate; anterior angles acutely rounded; posterior right, not at all rounded; 

 median impression very shallow, broad, deeper posteriorly; punctures fine and 

 dense. Elytra subparallel, slightly narrowed posteriorly; punctures very fine, 

 dense, confused; pubescence yellowish, fine, and dense. Head with front 

 subconvex, finely, densely punctured, the pubescence very short, reflexed at 

 the sides; antennae slender, the club large and prominent. Abdomen subopaque 

 below, densely, coarsely punctured parallelopipedus Melsheimer, page 121. 



Length 2.7 to 3.3 mm.; stout, comparatively broad, castaneous to nigro-piceous. Pro- 

 thorax with the sides slightly convergent posteriorly; anterior margin broadly 

 rounded or faintly trisinuate; anterior angles acutely rounded; posterior obtuse 

 and blunt; median impression broad, rather deep, more so jjosteriorly; punctures 

 coarse and dense, less so anteriorly. Elytra stout, slightly narrowed toward 

 the base; punctiu-es coarse, dense, faintly, subseriately arranged toward sides; 

 pubescence rather coarse, sparse, decumbent, and arranged in faint series. Head 

 with front convex, densely, subrugosely punctured, the pubescence short and 

 fine; epistoma nearly flat, coarsely punctured, side margins very faintly reflexed; 

 antennae stout, the club robust, small, oval. Abdomen polished below, extremely 

 finely and sparsely punctm-ed curtulus Casey, page 122. 



Subdivision B. (Xylotrogiis Stephens.) 



Length 2.5 to 3.5 mm.; castaneous throughout. Pronotum shiny, strongly punctured 

 posteriorly, the punctures becoming very small or obsolete anteriorly; side 

 margins strongly sinuate; anterior angles very broadly rounded. Elytra with 

 the sides nearly parallel; strial punctures fine, close-set, confused near suture; 

 interspaces flat; pubescence fine, decumbent, sparse. Head with front densely, 

 evenly punctured, feebly shiny, scarcely impressed before the eyes; epistoma 

 convex, finely punctured, not at all elevated at lateral margins. 



politus n. sp., page 122. 



Length 3 to 5 mm.; rufo-fuscous throughout. Pronotum subopaque; side margins 

 nearly straight, densely, finely serrulate and strongly convergent posteriorly; 

 anterior angles acute, slightly prominent, blunt, but scarcely rounded; punctures 

 more dense posteriorly, finer, not becoming obsolete anteriorly. Elytra with 

 the sides nearly parallel; strial punctures fine, impressed; interspaces, especially 

 toward sides, subconvex; pubescence fine, decumbent. Head with front densely, 

 rather coarsely punctured, convex, strongly impressed at the sides before the eyes; 

 epistoma subconvex, its anterior angles distinctly elevated. 



brunneus Stephens, page 123. 



Length 4.5 to 5 mm. ; rufo-testaceous, head and i^rothorax piceous. Pronotum opaque, 

 punctato-scabrous; anterior margin very broadly curved; side margins feebly 

 sinuate, rather strongly convergent posteriorly; anterior angles subprominent, 

 obtuse, very broadly rounded, posterior obtuse, not rounded; median impres- 

 sion merely a narrow, feebly impressed fm-row extending from near anterior
