286 MEMOIRS ON THE COLEOPTERA 



pressed; punctures of the foveal region numerous, notably coarse 

 and deep; inner fovea broadly, feebly impressed, the outer rounded, 

 rather large, feebly impressed; elytra barely a third longer than wide, 

 subevenly rounded behind the middle, equal in width to the pro- 

 thorax; striae coarse, impressed, coarsely, crenately punctate, the 

 scutellar not long, coarse, free; intervals feebly convex; lateral series 

 more widely spaced medially but not interrupted. Length (9 ) 6.2 

 mm. ; width 2.45 mm. New Jersey lubrica n. sp. 



Color rufo-piceous, the legs barely paler; elytra and entire hind body 

 beneath deep black; head nearly as in the preceding but still larger, 

 longer than wide, the antennae almost entirely missing in the type 

 but ferruginous and slender; prothorax only two-fifths wider than 

 long, parallel, the sides rounding and converging anteriorly; basal 

 angles rather broadly rounded at tip; apex nearly three-fourths as 

 wide as the base, broadly but distinctly sinuate, with bluntly rounded 

 angles; both transverse impressions obsolete, the stria very line; 

 punctures of the foveal region moderately numerous and very coarse, 

 the foveae irregular and very feebly impressed; elytra fully two-fifths 

 longer than wide, at the middle barely perceptibly wider than the 

 prothorax, gradually arcuately ogival posteriorly, the sides arcuate, 

 the surface highly polished in the female; striae finely groove-like, 

 not deep, scarcely at all impressed, the punctures minute and feeble; 

 scutellar stria short, free; lateral series not interrupted; intervals 

 very nearly flat; under surface unusually punctate, the first four ab- 

 dominal segments with rather close lateral punctures, the metasternal 

 sides and episterna with a few coarser punctures. Length (9 ) 6.8 

 mm.; width 2.85 mm. New York (Willets Point, Long Island). 



nigripennis n. sp. 



22 Sides of the pronotum rather abruptly and strongly flattened broadly 

 toward base, somewhat as in terrestris 23 



Sides of the pronotum not, or only very feebly or partially, flattened 

 postero-laterally 25 



23 Head rather well developed, distinctly more than half as wide as 

 the prothorax. Body stout, oblong-oval, moderately convex, piceous 

 above and beneath, the legs pale-flavo-testaceous, the femora some- 

 what slender; head scarcely as long as wide, with large and moder- 

 ately prominent eyes and short, very oblique strides ; antennae rufo- 

 ferruginous, not very slender, extending to the thoracic base in the 

 female; prothorax fully one-half wider than long, somewhat inflated, 

 the sides arcuate, scarcely more so, though more converging, api- 

 cally; basal angles much more than right, slightly blunt; apex more 

 than two-thirds as wide as the base, distinctly sinuate, with broadly 

 rounded angles; impressions obsolete, the stria very fine; foveal 

 punctures few in number and sparsely scattered, rather strong; 

 foveae feebly impressed and somewhat indefinite, the inner with a 

 deeper impressed line; elytra two-fifths longer than wide, at the mid- 

 dle very slightly wider than the prothorax, rather rapidly rounded 

 in about apical third; striae fine but impressed, with very fine punc- 

 tures, the scutellar moderate, oblique, widely free at tip; lateral
