the funicle long and very slender; prothorax nearly a third wider 

 than long, the sides subevenly arcuate, gradually more converging 

 anteriorly; apex truncate, half as wide as the base, the punctures 

 relatively rather coarse, deep and close but not quite in mutual 

 contact; median smooth line entire, narrow anteriad, broad pos- 

 teriad; basal lobe very short, broadly rounded; elytra three-sevenths 

 longer than wide, at the rather prominent humeri scarcely at all 

 wider than the widest part of the prothorax, almost four-fifths 

 longer; sides converging and barely visibly arcuate to the obtusely 

 rounded apex, which is however rather narrower than usual; grooves 

 moderate but very abrupt and deep; intervals not alternating much 

 and between two and three times as wide as the grooves, coarsely 

 punctato-rugose. Length (9) 3-6 mm.; width 1.38 mm. Ken- 

 tucky convergens n. sp. 



13 — Prothorax not evidently narrower than the elytra 14 



Prothorax distinctly narrower than the elytra 15 



14 — Oblong, not shining, black, the legs and antennae rufescent; squam- 

 ules above small but evident on the pronotum, broader though 

 linear, well separated but rather conspicuous and whitish on the 

 elytra, oval, dense and yellowish-white beneath; beak in the male 

 thick, rather tapering, very feebly arcuate, dull and strongly sculp- 

 tured, longer than the head and prothorax, the antennae inserted 

 near three-fifths, the club with a very minute basal tooth ; prothorax 

 not quite one-half wider than long, the broadly arcuate sides but 

 little more rounding and converging in about apical half; punctures 

 rather small and very densely crowded throughout, with the narrow 

 irregular smooth median line not quite entire; elytra very obtusely 

 subparabolic, the converging sides but feebly arcuate, the apex 

 obtusely rounded, scarcely a fourth longer than wide, with the 

 humeral prominences feeble, two-thirds longer than the prothorax; 

 striae rather coarse, deep; intervals not regularly alternating but 

 between two and three times as wide as the striae. Length (cf ) 

 4.2 mm.; width 1.9 mm. Arkansas (Little Rock). 



pinguescens Csy. 

 Oblong-suboval, more elongate, more convex and with more inflated 

 prothorax, black, not shining; beak in the male thick, strongly 

 sculptured, evenly and moderately arcuate, not quite as long as the 

 head and prothorax, the antennae inserted rather beyond three- 

 fifths, the basal tooth of the club acutely angulate, moderate but 

 distinct; prothorax two-fifths wider than long, the sides strongly 

 and subevenly arcuate throughout, widest just behind the middle; 

 apex fully half as wide as the base, the basal lobe rather prominent; 

 punctures not coarse though larger than in the preceding, very dense 

 throughout, without smooth median line, the squamules brownish- 

 white, small, not very slender but numerous and distinct; elytra 

 more regularly parabolic and longer, a third longer than wide, 

 hardly as wide as the widest part of the prothorax and about three- 

 fourths longer, the humeral swellings feeble; grooves deep; intervals 

 subequal, between two and three times as wide as the grooves, 

 coarsely punctato-rugose and with broadly linear and rather sparse
