Brazilian Barin/E 209 



ipes but still longer and more strongly rounded at apex, with the humeri 

 similar, distinctly more than twice as long as the prothorax; grooves and 

 general surface similar; characters of the legs and under surface almost 

 similar, except that the male abdominal impression is more broadly oval. 

 Length 6.8 mm.; width 3.6 mm. Brazil (Rio de Janeiro). October. One 

 specimen binaria n. sp. 



Form subsimilar but smaller in size and with the oblique sides ot the elytra more 

 arcuate; vestiture throughout similar and disposed in almost exactly the 

 same way; beak (cf) much shorter, though of the same general form, very 

 stout, only as long as the head and prothorax, the antennae at three-fifths 

 and similarly rufous and very slender but not so long, with the slender oval 

 club still smaller, its basal segment not longer than wide; prothorax similar 

 in form but with the apex evenly truncate and with the sparse punctures 

 almost coarse toward the sides and on the feeble anterior constriction; 

 basal lobe obtusely rounded, not sinuate; scutellum smaller, smooth through- 

 out, wider than long, with acute angles, strongly obtrapezoidal; elytra 

 shorter, more evenly ovoidal, barely more than a fourth longer than wide, 

 with rather smaller humeral prominences, evidently more than twice as long 

 as the prothorax; surface even, not feebly undulated as in binaria, the 

 grooves not quite so coarse, the intervals somewhat narrower, with the remote 

 infinitesimal punctules somewhat more evident; sexual characters almost 

 similar. Length 5.0-5.25 mm.; width 2.7-2.8 mm. Brazil (Rio de Janeiro). 

 October and November. Two male specimens canora n. sp. 



6 — Body pale red-brown in color throughout, the punctures of the elytral grooves 

 distinct. Form narrower and more elongate than in any other species, the 

 scales yellowish-white in color, a few slender and sparsely scattered at the 

 sides of the pronotum, those of the elytra broader in a cluster at the bases 

 of the second and third intervals and also a few remotely scattered along 

 the first and some other intervals, the scales of the under surface dense and 

 broad; beak (o 71 ) evenly and moderately arcuate, more cylindric and less 

 thick than in the preceding section, though subsimilarly sculptured and as 

 long as the head and prothorax; antennae near three-fifths, rufous and rather 

 slender, the first segment of the oval club somewhat wider than long, with 

 more arcuate sides; prothorax a third wider than long, the sides broadly, 

 subevenly arcuate, becoming parallel at base, the apex truncate, much less 

 than half as wide as the base; punctures fine and sparse, with an elongate 

 smooth area medially, but gradually coarse and closer toward the sides; 

 basal lobe evenly and gradually rounded, having a few fine squamules along 

 the edge; scutellum as in the preceding, but with less oblique sides; elytra 

 not quite one-half longer than wide, subevenly parabolic, two and one-half 

 times as long as the prothorax, the grooves rather coarse, more than a third 

 as wide as the intervals, which have sparse infinitesmal punctures, those 

 bearing squamules larger and distinct; basal abdominal concavity of the 

 male deep and abrupt, bearing long slender hairs, contrasting greatly with 

 the broad dense scales of the rest of the surface; inferior femoral fringe 

 dense, not entire. Length 4.25 mm.; width 1.9 mm. Brazil (Chapada — 

 forest). November. One male, on flowers in clearing angustior n. sp. 



Body less slender, black, the prothorax sometimes obscure rufous or piceous, the 

 punctures of the elytral grooves less evident 7 



7 — -Body stouter and with larger prothorax, the sutural interval very sparsely 

 squamose; color deep black and shining, the prothorax sometimes faintly 

 piceous, the legs and beak piceous; beak (9) arcuate as in all the other 

 species, evidently longer than the head and prothorax, sculptured as usual, 

 rather thick, thinner and more cylindric distally; antennae medial, rather 

 long and slender, rufous, the club shorter than usual, oval, only as long as
