Brazilian Barin.e 37 



the sides converging and very evenly, moderately arcuate, becoming just 

 visibly more arcuate anteriad to the large apical tubulation, two-fifths as 

 wide as the base; surface very even, rapidly declivous apically to the tubu- 

 lation; basal lobe evenly rounded, margined with some distinct punctures, 

 without adjoining basal impressions; scutellum rather small, short, smooth, 

 broadly canalate, the apex sinuate and bicuspid; elytra slightly longer than 

 wide, nearly a third wider than the prothorax, parabolic, the humeral promi- 

 nences laterally very conspicuous; striae very feeble, finely, remotely punctu- 

 late, more polished than the intervals; tibiae plectrate externally near base; 

 abdomen with the quadrate raised basal area rather finely, sparsely punctate, 

 deeply impressed medially, transversely so along the base. Length 9.0 mm.; 

 width 6.0 mm. Brazil (Santarem). One specimen breviscutis n. sp. 



Form rhombic-oval, rufo-piceous and smooth above, elsewhere black; beak rather 

 short, very feebly arcuate, three-fifths as long as the prothorax, strongly 

 sculptured, flattened at the sides; antennae very short, the thick suboval 

 club as long as the funicle; prothorax a fourth wider than long, the sides 

 strongly converging, broadly and evenly arcuate from base to tubulation, 

 the latter scarcely more than a third as wide as the base, the basal lobe rather 

 narrowly and evenly rounded, subimpunctate, the disk at each side at base 

 with a deep subfoveiform impression; surface evenly convex; scutellum flat, 

 rather small, somewhat longer than wide, parallel, truncate and finely, 

 sparsely punctulate; elytra but little longer than wide, a fourth wider than 

 the prothorax, subcuneate, with arcuate sides, the humeral prominences 

 rather broadly rounded; striae very fine, almost obliterated, excepting the 

 sutural, all having small and remote punctures; abdominal impression 

 sparsely punctate, the punctures coarse subbasally, small thence posteriad; 

 tibiae acutely and strongly dentate externally near the base. Length 5.6 

 mm.; width 4.0 mm. Brazil (Rio de Janeiro). October. One example. 



curtirostris n. sp. 



9 — Body notably large, very obscure piceous above, smooth and slightly aluta- 

 ceous; beak ( 9 ) feebly arcuate and strongly punctate on the flattened sides, 

 finely so dorsally, almost as long as the prothorax, with narrow feebler groove 

 beyond the antennae, the latter being well behind the middle, or (cf) much 

 shorter, still more strongly punctate at the sides, with broad groove, the 

 antennae more nearly at the middle; antennal club a little shorter than the 

 funicle; prothorax nearly as long as wide, with converging and feebly arcuate 

 sides to the feebly marked prominence at the middle, thence gradually more 

 rounding to the tubulation; basal lobe obtusely rounded, sometimes feebly 

 impressed and more or less punctate; scutellum quadrate, feebly convex, 

 sometimes a little longer than wide; elytra cuneate, slightly elongate, nar- 

 rowly rounded at tip, almost a third wider than the prothorax, the converging 

 sides straight behind the broadly rounded humeri; striae fine and feeble, 

 slightly more shining than the intervals and with remote and feeble punctures, 

 the sutural not stronger basally; sides of the inferior hind femoral sulcus (c?) 

 fimbriate, and with the outer edge acutely dentate at the distal sinus; ab- 

 domen broadly concave and densely punctate and setulose basally in both 

 sexes. Length 10.5-10.8 mm.; width 6.8-7.0 mm. Brazil (Chapada). 

 September to November. Three specimens cuneipennis n. sp. 



Body nearly as in the preceding but slightly smaller and less stout; beak (9) 

 not so long and distinctly shorter than the prothorax, cylindrical, nearly 

 smooth and only very minutely and remotely punctulate, especially distad, 

 though the flattened sides at base are rather strongly punctate, the anntenae 

 near basal third, or (d\) shorter, less cylindric, finely punctured, but with the 

 flattened sides strongly punctate throughout, with broader and longer channel 

 beyond the antennae, which are just behind the middle, the club shorter than
