Brazilian Baring 465 



twice as long; sides parallel and nearly straight; apex rapidly and broadly 

 rounded; striae fine; interstitial punctures large, transversely oval and almost 

 in mutual contact. Length 2.25 mm.; width 1.0 mm. Brazil (Chapada — 

 forest). November. One specimen piceipes n. sp. 



Form much narrower, oblong-suboval, convex, black, with more or less dark 

 rufo-piceous legs; silvery setules of the elytra smaller, less close and less 

 conspicuous, the interstitial punctures transversely and finely lineate, more 

 widely separated; antennal club relatively larger 2 



2 — Beak (o 71 ) moderately thick, as long as the head and prothorax, evenly, 

 somewhat strongly arcuate, equal throughout, finely, sparsely punctate, 

 more strongly and densely toward base, the entire surface with extremely 

 minute strigilation, giving a sericeous lustre; antennae just visibly beyond 

 the middle, obscure rufous, the first funicular joint longer, equal to the 

 next four, the outer joints compact, gradually a little wider, the elongate- 

 oval and equally segmented pubescent club as long as the five preceding 

 joints; prothorax short, two-fifths wider than long, the outline nearly as in 

 the preceding; apex four-sevenths as wide as the base; punctures similar, 

 deep and dense, but separated medially by half their widths; scutellum with 

 a shallow opaque concavity; elytra a third longer than wide, nearly a fifth 

 wider than the prothorax and fully two and one-half times as long, parallel, 

 with straight sides, obtusely rounded at apex; grooves very moderate, the 

 transverse fine punctures rather well separated; tarsi very slender, the third 

 joint scarcely dilated. Length 2.45 mm.; width 0.85^1111. Brazil (Cha- 

 pada). March. One specimen brevicollis n. sp. 



Beak (o 71 ) thicker, scarcely longer than the prothorax, strongly arcuate, finely, 

 sparsely strigilate but shining, the minute punctures only moderate and 

 well separated basally; antennae piceous, medial, the first funicular joint as 

 long as the next three, the others short and transverse, the club larger, 

 oval, longer than the six preceding joints; prothorax much narrower, only 

 a fourth wider than long, the sides feebly converging and slightly arcuate, a 

 little more so apically; apex nearly three-fifths as wide as the base; punc- 

 tures almost as in the preceding but not quite so deep, slightly separated 

 medially; scutellum small, oblong, impressed along the middle; elytra 

 fully a third longer than wide, more than a fourth wider than the prothorax 

 and distinctly over twice as long, the parallel sides straight; apex obtusely, 

 subcircularly rounded; sculpture somewhat as in the preceding. Length 

 1.8 mm.; width 0.7 mm. Brazil (Chapada — forest). November. One 

 specimen morosa n. sp. 



Beak (c 71 ) rather thick, feebly tapering, somewhat strongly arcuate and coarsely, 

 densely and rugosely punctate throughout, though somewhat shining, almost 

 as long as the prothorax; antennae blackish, just visibly beyond the middle, 

 rather slender, the first funicular joint as long as the next four, the others 

 not very compact and only moderately transverse, slightly increasing, the 

 narrowly oval pubescent club as long as the preceding five joints; upper 

 surface of the body more shining; prothorax a third wider than long; sides 

 feebly converging, gradually rounding beyond the middle; punctures moder- 

 ate in size, deep, less dense than in the preceding, separated by more than 

 half their widths medially, without smooth line; scutellum differing in being 

 coarsely, densely punctate throughout; elytra a third longer than wide, 

 fully a fourth wider than the prothorax and distinctly more than twice as 

 long; sides parallel, very feebly arcuate, gradually, then broadly and obtusely, 

 rounding behind the middle; grooves deep, rather coarser, half as wide as 

 the intervals, the serial punctures of which are more sharply defined, more
