212 MEMOIRS ON THE COLEOPTERA 



the elytra rather closely reticulate in transverse broken lines; head 

 convex, nearly three-fourths as wide as the prothorax, the eyes small, 

 prominent, feebly setulose; antennae slender, fuscous, paler basally, 

 moniliform, barely two-thirds as long as the elytra; prothorax one- 

 half wider than long, equally wide at base and apex, the sides strongly 

 rounded anteriorly, oblique and straight behind, the angles obtuse 

 but not rounded, feebly reflexed; subbasal sulcus deep, angulate, 

 the anterior impression broad and obvious, the stria fine; elytra 

 two-fifths longer than wide, two-thirds wider than the prothorax, 

 oval, with arcuate sides becoming straight basally, much wider just 

 behind the middle than at base, the humeri obtuse; edge near and 

 around the humeri bearing a series of minute erect setae; sutural 

 stria deep and distinct, the second fine and feeble; foveae near basal 

 and apical third. Length 1.21.4 mm.; width 0.450.55 mm. Vir- 

 ginia (Norfolk). Five examples congestus n. sp. 



Hind body longer, not so broadly oval 3 



3 Body elongate-oval, strongly convex, the integument rather thicker 

 and firmer than usual. Color bright testaceous throughout, the 

 head barely darker, the surface shining, the ground sculpture nearly 

 as in the preceding; head two-thirds as wide as the prothorax, convex, 

 the anterior impressions feeble; eyes small, not prominent, feebly 

 setulose; antennae fusco-testaceous, scarcely three-fifths as long as 

 the elytra; prothorax formed nearly as in the preceding, the sides 

 less strongly and more broadly rounded, straight only near the very 

 obtuse but bluntly subprominent angles, the sides of the base no- 

 tably oblique; subbasal impression deep, angulate, the anterior obso- 

 lete, the median stria fine; elytra notably long, almost evenly oval, 

 widest at the middle, parallel, with arcuate sides, two-thirds longer 

 than wide, only two-fifths wider than the prothorax; pedicel slightly 

 less than half the basal width; minute erect setae of the edge at and 

 behind the humeri marking a very feeble serrulation; sutural stria 

 rather deep, none other evident; foveae minute, near basal and apical 

 third. Length 1.2-1.3 mm.; width 0.35-0.45 mm. Pennsylvania. 



unistriatus n. sp. 



Body more oblong, not so convex, sometimes distinctly depressed, the 

 integument thinner as a rule 4 



4 Elytra long, parallel, but little wider than the prothorax. Body 

 elongate, moderately convex, subparallel, pale brownish-testaceous 

 in color throughout, shining, the pronotum without ground sculp- 

 ture, the reticulation of the elytra fine and strigiliform; head three- 

 fourths as wide as the prothorax, the eyes small, nude and prom- 

 inent; antennae fuscous, paler basally, scarcely three-fifths as long 

 as the elytra; prothorax short, two-thirds wider than long, fully as 

 wide at base as at apex if not somewhat wider, the sides moder- 

 ately rounded anteriorly, oblique and straight in about basal half, 

 the angles obtuse, blunt, the sides of the base oblique; seta placed 

 at the angle as usual in 'this group; subbasal sulcus deep, angulate, 

 the anterior impression visible medially; elytra nearly three-fourths 

 longer than wide, a third wider than the prothorax, evenly parabolic 

 in fully apical third, the parallel sides feebly arcuate, the humeri
