Barin^e 427 



rounded at the sides, more oblique anteriorly, with the punctures 

 distinctly larger and much less closely crowded, the elytra shorter, 

 w^ith somewhat more oblique and more arcuate sides, the beak 

 longer, slender, smooth, about half as long as the body, feebly 

 arcuate, bent at base and with the antennae inserted at four-sevenths. 

 In both sexes the thoracic apex is more than half as wide as the 

 base, the elytral apex obtusely rounded, the humeral swellings 

 rather prominent and the strial intervals subequal and between 

 two and three times as wide as the grooves, closely punctate- 

 rugose as usual. Length (cf 9 ) 3.35-4.2 mm.; width 1.4-1.8 mm. 

 Indiana, Kentucky and Missouri (St. Louis). Sixteen specimens. 



salebrosus Csy. 



19 — Body larger, rather stouter and more convex than in the preceding, 

 deep black throughout, somewhat shining, the squamules of the 

 upper surface small, fine, sparse and very inconspicuous even on the 

 elytra, the moderately large oval whitish scales of the under surface 

 evidently though narrowly separated; beak in the male thick, 

 feebly tapering, very slightly arcuate, bent at base, strongly sculp- 

 tured but not very much flattened at the sides, as long as the head 

 and prothorax; antennae inserted at three-fifths, the outer funicular 

 joints barely wider than long, the tooth of the club obtuse and 

 inconspicuous; prothorax large, very convex, with the upper profile 

 strongly arcuate and obliquely sloping and straight anteriorly, only 

 a fifth wider than long, the sides subparallel and feebly, evenly 

 arcuate, gradually a little more so and strongly converging anteriorly; 

 apex scarcely half as wide as the base; punctures very moderate and 

 extremely dense throughout, the smooth median line evident 

 centrally; elytra evenly parabolic, scarcely a fourth longer than 

 wide, at the rather prominent humeri evidently wider than the 

 prothorax, only about three-fifths longer, the grooves rather narrow 

 but deep, the punctato-rugose intervals subequal and from slightly 

 less to more than three times as wude as the grooves. Length (cf ) 

 4.2-4.75 mm.; width 1.65-2.0 mm. Indiana. Two examples. 



convexus n. sp. 



20 — Prothorax coarsely punctate. Body oblong-suboval, convex, some- 

 what shining, pale ferruginous-red in the type, the squamules of 

 the upper surface small, sparse and entirely inconspicuous; beak 

 in the female smooth, rufo-piceous, feebly tapering, distinctly 

 arcuate, straighter apically, not half as long as the body, the antennae 

 inserted just beyond the middle; prothorax short, one-half wider 

 than long, the upper profile strongly arcuate, obliquely sloping and 

 straighter anteriorl}- ; sides evenly and strongly rounded in about 

 anterior, becoming parallel and nearly straight in basal, half; apex 

 feebly constricted and not quite half as wide as the base, the basal 

 lobe short and broad; punctures close-set or subcontiguous; smooth 

 median line visible except toward base and apex and somewhat 

 tumid; elytra subparabolic with the apex rather rapidly obtuse, a 

 fourth longer than wide, at the moderate humeri very little wider 

 than the prothorax, four-fifths longer; grooves moderate, deep, the 

 strongly punctato-rugose intervals subequal and about three times
