slightly wider than long, parallel, with very evenly, circularly 

 rounded sides; base transverse, as wide as the apex, which is deeply 

 sinuate, with rather sharply marked angles; surface convex, even, 

 not impressed, the stria extremely fine and not entire; foveae small, 

 deep, punctiform, with a short feeble extension visible by obliquely 

 reflected light; elytra three-fifths longer than wide, one-half wider 

 than the prothorax, gradually ogival behind, with faint sinus; 

 humeri not very rapidly more rounded; striae deep, grooved, feebly 

 impressed; intervals moderately convex (cf) or somewhat feebly 

 so (9), the scutellar stria long; anterior male tarsi not strongly 

 though distinctly dilated. Length (cf 9) 7-5-7-8 mm.; width 

 2.7-3.0 mm. Rhode Island to North Carolina (Southern Pines) 

 and Alabama (Mobile). [PI. foveicolUs Chd.] punctiformis Say 



Legs clear rufous or rufo-flavate throughout, the femora sometimes shaded 

 a little darker 4 



4 — Body larger and elongate but stouter and more ventricose than in 

 the preceding, similarly deep black; head moderate, the antennae 

 as usual in form and color but relatively shorter, always distinctly 

 less than half as long as the body, the third and fourth joints sub- 

 equal; prothorax throughout nearly as in punctiformis; elytra 

 broader, one-half longer than wide to but little more, fully three- 

 fourths wider than the prothorax, the apex somewhat more obtuse; 

 striae rather coarse, deeply impressed, with distinctly convex in- 

 tervals, becoming flatter externally; met-episterna fully twice as 

 long as wide; anterior male tarsi very feebly dilated as in the pre- 

 ceding; the under surface of the hind body is densely opaque except 

 broadly along the median line. Length (cf" 9) 7.5-9.2 mm.: 

 width 2.6-3.3 mm. Ohio, Missouri, Kansas, Texas (Galveston and 

 Austin) and Arizona (Tugson) — the femora slightly darker in the 

 latter specimen. Also recorded from northern Mexico by Bates, 

 under the name punctiformis rufipes Dej. 



Body smaller and narrower than in rufipes and more slender than in 

 punctiformis, polished and deep black in both sexes, the lateral sub- 

 opaque areas beneath much more restricted, often confined to the 

 met-episterna; legs very pale flavo-rufous; head nearly three- 

 fourths as wide as the prothorax, with well developed and slightly 

 prominent eyes, only slightly elongate, the antennae very slender, 

 piceous, paler basally; prothorax throughout nearly as in puncti- 

 formis, except that the foveae are more evidently prolonged for a 

 short distance; elytra notably elongate, still narrower, parallel, 

 nearly three-fifths longer than wide, one-half to three-fifths wider 

 than the prothorax, gradually rounded behind, with feeble sinus; 

 striae feebly impressed, finer than in punctiformis or rufipes and 

 with the punctures very fine, sometimes scarcely traceable; intervals 

 only feebly convex; anterior male tarsi feebly dilated and smooth, 

 the intermediate joints notably short. Length (cf 9 ) 6.5-8.0 mm.; 

 width 2.3-2.7 mm. Maryland (Hagerstown) to Kansas (McPher- 

 son). Seven examples rubripes Zimm. 



Body smaller than in punctiformis and much more abbreviated, similarly 

 more ventricose than in rubripes, convex; under surface black to
