BARINiE 423 



little wider than the widest part of the prothorax, fully three-fourths 

 longer; grooves coarse, very abrupt and deep; intervals from less 

 than two to about three times as wide as the grooves, coarsely, 

 closely and confusedly punctate. Length (9) 6.0 mm.; width 2.8 

 mm. Kansas (locality unrecorded) robustus n. sp. 



Body less broadly and more rhomboidally oval, convex, not so shining 

 and more densely sculptured, black throughout; squamules of the 

 upper surface small and slender, whitish, sparse but distinct; beak 

 (cT) arcuate, stout and sulcate, punctate, dull, minutely, sparsely 

 squamulose and a little longer than the head and prothorax, or 

 ( 9 ) a little longer, smooth and more cylindric, similarly more rapidly 

 arcuate at base; antennae (cf ) moderate in length, the last funicular 

 joint transverse, the club large, rather thick, with distinct tri- 

 angular internal basal tooth, or ( 9 ) with longer, very much more 

 slender funicle and smaller, narrower club; prothorax almost one- 

 half wider than long, the sides subevenly rounded, more converging 

 anteriorly, widest but little before the base; punctures not quite so 

 coarse as in the preceding and almost in mutual contact, with more 

 or less evident smooth line centrally; elytra parabolic, a sixth (9 ) 

 to a fourth (cf ) longer than wide, at the prominent humeri distinctly 

 wider than the prothorax, the grooves very deep and abrupt; 

 intervals two to three times as wide as the grooves, coarsely, closely 

 punctate. Length (cf 9) 5.6-5.75 mm.; width 2.65 mm. North 

 Carolina denticomis Csy. 



Body rather smaller and less stout, oval or oblong-oval, convex, black 

 throughout, slightly shining, the squamules above small and whitish 

 but sparse and rather inconspicuous though very evident on the 

 elytra, oval, dense and white beneath, fine and rather sparse on the 

 femora; beak (cf ) rather thick, dull and strongly sculptured, much 

 longer than the head and prothorax, nearly straight, gradually 

 arcuate basally, or (9) somewhat longer, smooth, gradually and 

 distinctly tapering, arcuate, rapidly more so in about basal half; 

 antennae inserted at three-fifths (cf) or four-sevenths (9), the 

 funicle (cf ) with the last joint much larger and transverse, the tooth 

 of the club relatively small, or (9 ) very slender, the club smaller; 

 prothorax a third (cf ) to nearly one-half (9) wider than long, the 

 sides subevenK' arcuate, more so in the female; punctures deep, 

 rather coarse and very close though narrowly separated, the median 

 smooth line narrow, more or less distinct and somewhat tumid; 

 elytra obtusely parabolic, very much wider in the female, only very 

 slightly wider than the prothorax and three-fourths longer; grooves 

 moderately coarse, very deep; intervals two to nearly three times 

 as wide as the grooves, coarsely, closely punctate. Length (cf 9 ) 

 4-75~5-o mm.; width 2.0-2.3 ^^- Missouri and Mississippi 

 (Vicksburg). Five specimens missourianus n. sp. 



Body very much smaller than in any of the preceding species of this 

 section, rather narrow and gradually attenuate behind, black, some- 

 what shining; upper squamules small, slender, not close and incon- 

 spicuous; beak in the female slender, smooth, arcuate, nearly half 

 as long as the body, the antennae inserted just beyond the middle,
