Brazilian Barin^e 49 



arcuate to the tubulation; basal lobe with scattered punctures, the lateral 

 impressions small but deep; scutellum subquadrate, well developed, nearly 

 flat and even, distinctly wider than long and with the minute punctures 

 rather numerous; elytra somewhat obtusely oval, not longer than wide, 

 a fourth wider than the prothorax and less than one-half longer, the moder- 

 ately prominent humeri evenly rounded; striae very fine and minutely, 

 remotely punctulate, the sutural and two marginal deep, the ninth, especially, 

 broad and catenulate; abdominal plaque sparsely punctate, abruptly and 

 deeply impressed at the middle toward apex; hind tibial tooth large, very 

 aciculate at apex. Length 4.5 mm.; width 3.2 mm. Brazil (Chapada — 

 forest). November. One specimen — apparently female. . .aterrimus n. sp. 

 Antennal club very stout, always at least obviously shorter than the funicle. . .32 



32 — Upper surface polished but with alutaceous pronotum 33 



Upper surface very highly polished throughout 34 



33 — Body larger, rhomboidal; beak cylindric, very feebly arcuate, only three- 

 fifths as long as the prothorax, the sides only feebly flattened basally and 

 deeply and loosely, but not very coarsely, punctate, very finely and sparsely 

 so anteriorly and throughout above; head sparsely punctate; prothorax a 

 a fourth wider than long, the sides only moderately converging and broadly 

 arcuate, rapidly more rounding anteriorly to the abrupt tubulation; surface 

 with the minute and sparse punctulation unusually evident, the lobe broadly, 

 deeply sinuate, and with some coarser punctures, the lateral impressions 

 shallow; median line flat, but abruptly and narrowly impunctate; scutellum 

 rather large, quadrate, somewhat wider than long, rounded at base, the 

 punctulation minute and sparse; elytra slightly elongate, between a fourth 

 and fifth wider than the prothorax, briefly cuneate, obtusely rounded at 

 apex, the rounded humeri rather prominent; striae very fine and subobsolete, 

 but with the punctures unusually strong, the sutural deep, the second less so, 

 the ninth very coarsely excavated, except near base, the tenth also rather 

 coarse; sparse punctulation of the intervals rather evident; abdominal 

 plaque somewhat strongly but sparsely punctate, nearly flat, transversely 

 impressed at base and medially toward apex; tibial tooth large, with very 

 aciculate apex. Length 5.8 mm.; width 4.3 mm. Brazil (Chapada). 



November. One specimen anthrax n. sp. 



Body not so large; beak not two-thirds as long as the prothorax, not quite so 

 cylindric, a little more flattened and rugosely punctate at the sides basally, 

 the grooves beyond the antennae deep and distinct; punctures above sparse 

 and minute apically, rather strong and still sparser basally; prothorax a 

 fourth wider than long, the sides strongly converging, distinctly and sub- 

 evenly arcuate from base to tubulation; surface nearly as in the preceding 

 but with much more narrowly sinuate basal lobe; median line finely, very 

 faintly subcarinulate; scutellum relatively still larger, somewhat transversely 

 subquadrate, rounded at base and with distinct and numerous punctules; 

 elytra not quite as long as wide, in outline and general relationship almost as 

 in the preceding, but with the sides more arcuate; striation nearly similar, 

 the ninth stria not quite so coarse, the distant punctures more minute and 

 much less conspicuous; abdominal plaque nearly similar, but with the punc- 

 tures still more minute and remote; hind tibiae less broad, the tooth smaller; 

 at the sides of the pronotum the punctures become rather strong and con- 

 spicuous, though sparse, in a way not noticeable in anthrax. Length 4.7 



mm.; width 3.6 mm. Brazil (Chapada) curtipennis n. sp.
