rather strongly rounded behind in apical two-fifths, without trace 

 of sinus; striae fine, the scutellar rather short, oblique, the discal 

 puncture at three-fifths; hind tarsi a little longer than in badiipennis; 

 middle tarsi (cf ) very slender. Length (cf) 4.9 mm.; width 1.8 mm. 

 New York (West Point), Wirt Robinson properus n. sp. 



4 Body oblong-suboval, rather convex, strongly shining, piceous-black, 

 the thoracic margins finely rufous, the elytra dark testaceous, with a 

 large blackish cloud except basally and along the suture ; under surface 

 black, the epipleura and legs bright testaceous; head rather short, 

 three-fifths as wide as the prothorax, with well developed and promi- 

 nent eyes; surface smooth throughout; antennae slender, dark, the 

 first three joints rufous; prothorax two-fifths wider than long, widest 

 near apical third, the sides strongly rounded, oblique basally, be- 

 coming sinuate only at the obtuse though sharp and minutely 

 prominent angles; base transverse, only beaded very near the angles, 

 evidently wider than the very moderately sinuate apex; surface as in 

 badiipennis, except that the foveae are larger, deepei and more 

 rounded and with coarser and denser punctures, which spread finely 

 and sparsely far beyond the foveae and to the sides, the latter narrowly 

 punctured a far as the apex; elytra not quite one-half longer than 

 wide and two-fifths wider than the prothorax, parallel, with very 

 obtusely ogival apex, the sinus represented by a slightly straighter 

 edge; striae somewhat fine but strongly impressed, the scutellar 

 rather long and deep; intervals broadly convex, strongly so suturad. 

 Length (cf ) 5.0 mm.; width 1.9 mm. Long Island . [Tachycellus

Body oblong-suboval, more elongate than in kirbyi, shining; head deep 

 black; prothorax testaceous, with a large transverse central black 

 area; elytra testaceous, with a large common feeble blackish cloud, 

 the suture testaceous at least posteriorly; under surface and legs as 

 in the preceding; head very smooth, more elongate, nearly two-thirds 

 as wide as the prothorax, the antennae as in kirbyi; prothorax two- 

 fifths wider than long, widest at apical third, the sides strongly 

 rounded, oblique, becoming gradually feebly sinuate near the obtuse 

 hind angles, which are sharp and minutely, distinctly prominent; 

 base transverse, becoming abruptly strongly oblique but scarcely 

 at all beaded at the sides, as wide as the sinuato-truncate apex, some- 

 times apparently a little narrower; surface as in kirbyi, except that 

 the coarse widely disseminated punctures are confined to the latero- 

 basal regions, only a few being scattered along the finely reflexed 

 edges; elytra fully one-half longer than wide, not quite one-half wider 

 than the prothoiax, the striae and convex intervals nearly as in 

 kirbyi, the discal puncture near three-fifths (cf ) or two-thirds (9 ); 

 hind tarsi rather long and slender. Length (cf 9 ) 6.06.3 mm.; 

 width 2.1-2.3 rnm. Pennsylvania, North Carolina and Illinois. 

 Rather abundant. [Feronia atrimedia Say and Trechus similis
