48 MEMOIRS ON THE COLEOPTERA 



surface and legs ochreo-testaceous; head large, about half as wide 

 as the prothorax, minutely and sparsely but rather deeply punctate, 

 the front very broadly arcuate between the antennal sinuses; an- 

 tennae well developed; prothorax unusually long, barely more than 

 twice as wide as long, the sides strongly converging and evenly, 

 feebly arcuate from base to apex, the basal bead distinct medially; 

 scutellum broadly, very obtusely ogival; elytra slightly longer than 

 wide, only very little more than twice as long as the prothorax, the 

 arcuate sides rounding more posteriorly; surface nearly even, the 

 punctures sparse and inconspicuous; each elytron in the type has 

 two short supplementary true striae behind the middle, spaced like 

 the first and second regular striae; metasternal process broad, the 

 mesosternum rather broad at its sides anteriorly. Length 2.8 mm.; 

 width 1.6 mm. New York (Willets Point, Long Island). 



sternalis n. sp. 



8 Antennae shorter, the funicle rather shorter than the club, the third 

 joint strongly obconic and scarcely twice as long as wide. Body 

 very small, not very broadly oval, obtuse behind, sometimes piceous 

 in color, darker beneath, the legs pale; head half as wide as the pro- 

 thorax, very minutely, remotely punctulate, the front trapezoidal 

 between the eyes, which are coarsely faceted; prothorax short, 

 much more than twice as wide as long, the sides rather strongly 

 converging and arcuate, the basal bead moderately distinct; scu- 

 tellum sharply ogival, scarcely one-half wider than long; elytra not 

 quite three times as long as the prothorax, rounding obtusely at apex, 

 polished though almost everywhere with excessively faint strigilato- 

 reticulate sculpture, becoming coarser micro-reticulations at apex, 

 the punctures of the widely separated series fine; metasternal process 

 broad, extending rather beyond the coxae, arcuato-truncate at apex 

 and everywhere very finely beaded. Length 1.35-1.7 mm.; width 

 0.7-1.15 mm. Illinois (Highland Park) to New York (Lake Champ- 

 plain). Twenty-one examples impotens n. sp. 



Antennae less abbreviated, the funicle longer and more slender, the third 

 joint much more than twice as long as wide and as long as the next 

 two combined as usual : 9 



9 Form rather broadly oval, obtuse behind, highly polished, the under 

 surface dark, the legs pale; head rather small, not quite half as wide 

 as the prothorax, the punctures fine but strong and not very re- 

 motely separated; front somewhat produced and trapezoidal between 

 the eyes, which are coarsely faceted, the facets narrowly separated 

 among themselves; prothorax somewhat more than twice as wide as 

 long, the converging sides arcuate; basal bead moderately distinct; 

 scutellum sharply ogival, three-fourths wider than long; elytra but 

 slightly longer than wide, subparallel in about basal half, the surface 

 smooth, becoming very finely and feebly strigilato-reticulate on the 

 flanks posteriorly; metasternal process very broad, extending some- 

 what beyond the coxae and very finely beaded throughout. Length 

 1.65-2.0 mm.; width 0.85-1.2 mm. Vermont, New Hampshire and 

 New York (Lake Champlain). Nine examples. . .neglectus Csy.
