are broadly rounded and almost obliterated; base broadly arcuate, 

 a little wider than the distinctly sinuate apex; edges thickened 

 about the basal angles; fovese very shallow and broad, less shining 

 though scarcely rugose, having a small lineate and more impressed 

 part internally; anterior impression feeble; elytra parallel, with 

 very feebly arcuate sides, rounded at base, almost one-half longer 

 than wide, fully two-fifths wider than the prothorax; apex gradually 

 arcuately narrowing, the sinus distinct, rather short; striae smooth, 

 not fine, deep, not much more impressed apically; intervals not 

 quite flat, the three punctures all near the third stria. Length 

 8.0 mm.; width 2.8 mm. A single example, sent by Mr. Leng as 

 probably having been taken somewhere in British America. 



aethiops n. sp. 



Form ventricose, much smaller in size lo 



10 — Body moderately stout, convex, polished, black in both sexes; 

 legs and tarsi black, with short fulvous setae; head three-fifths as 

 wide as the prothorax, rather elongate, with well developed and 

 rather prominent eyes, the palpi black, slender; impressions broad 

 and rather deep; antennae black, slender, more than half as long as 

 the body, the third joint a little shorter than the fourth; prothorax 

 a third to two-fifths wider than long, the strongly rounded parallel 

 sides narrowly reflexed anteriorly, gradually more broadly thence 

 posteriorly, strongly reflexed at base, the angles broadly rounded; 

 base not or but slightly wider than the sinuate apex, not margined 

 medially, arcuate laterally; surface very nearly as in harrisi, the 

 foveae deeper and nearly smooth, the surface laterally very feebly 

 convex; apical angles very blunt at tip; elytra more oval, shorter, 

 not one-half longer than wide, gradually rounding behind the middle, 

 the sinus long but very faint; sides more arcuate; striae fine, dis- 

 tinctly impressed, almost smooth, deeper at apex; intervals broadly 

 convex; two anterior punctures near the third stria, the third near 

 the second; ninth stria half as far from the edge as from the eighth; 

 anterior male tarsi rather distinctly dilated. Length (cf 9 ) 7-7- 

 7.9 mm.; width 3.2-3.3 mm. Rhode Island (Boston Neck). Three 



specimens fidele n. sp. 



Body somewhat as in fidele but still more ventricose and with smaller 

 prothorax, similar in coloration and lustre; head similar but re- 

 latively larger, almost two-thirds as wide as the prothorax; antennae 

 slightly shorter, though fully half as long as the body, the joints 

 shorter, the third and fourth more nearly equal; prothorax relatively 

 smaller and less transverse, scarcely more than a fourth wider than 

 long, otherwise similar, except that the sides are rather less strongly 

 arcuate; base barely wider than the apex, with ver}^ broadly rounded 

 and similarly reflexed angles, the foveae similar and notably deep, 

 nearly smooth, the surface thence to the sides flat and more rugulose 

 than in fidele; elytra nearly similar in form and striation but fully 

 three-fifths wider than the prothorax, the sinus very feeble, more 

 abruptly oblique, the external curvature being narrower than in 

 fidele; striae still more impressed, stronger; intervals rather strongly 

 convex, the three dorsal punctures similarly situated; anterior
