Brazilian Baring 39 



concave along the base, the remainder broadly and feebly concave; tibiae 

 nearly similar. Length 6.9 mm.; width 4.7 mm. Brazil. Desbrochers 



des Loges incertus n. sp. 



Body a little shorter and broader, still more rhombiform, the upper surface similar 

 in coloration and in the alutaceous lustre; beak nearly similar but not quite 

 so slender and slightly shorter than the prothorax, the antennal club stout, 

 gradually pointed and distinctly shorter than the funicle; prothorax longer, 

 barely wider than long, the sides less converging from the base, only feebly 

 arcuate, becoming more rounded anteriorly; surface nearly even; basal 

 lobe broader, truncate, plentifully punctate, smooth at the middle, not im- 

 pressed laterally; the punctures become fine along the base laterally and the 

 entire surface has infinitesimal sparse punctulation; elytra not longer than 

 wide, nearly a third wider than the prothorax, more abruptly expanding 

 behind the latter and with rather more prominent — though broadly rounded 

 — humeri than in incertus; scutellum larger, quadrate, wider than long, 

 minutely, sparsely punctulate, broadly sinuato-truncate but not impressed 

 at tip; abdominal plaque nearly flat, impressed medially behind, rather 

 strongly, closely punctate and with numerous thick shining setae, which are 

 much longer and coarser than in incertus, the subbasal tibial tooth large and 

 acute. Length 6.8 mm.; width 4.9 mm. Brazil. Desbrochers des Loges. 



semistriatus n. sp. 



10 — Scutellar stria distinct to the scutellum though fine. Body rhomboid-oval, 

 black, dark piceous throughout above, faintly alutaceous; beak as long as 

 the convex part of the prothorax ( 9 ), a little shorter (o 71 ), distinctly punc- 

 tured throughout and coarsely so on the flattened sides basally (0"), or 

 almost impunctate except at the sides basally ( 9 ) ; antennal club elongate- 

 oval, a little shorter than the funicle; prothorax a fourth wider than long, 

 the feebly converging sides slightly arcuate, gradually more so anteriorly; 

 surface evenly convex, a little less so in the male; basal lobe feebly punctulate, 

 truncate, not distinctly impressed laterally; scutellum moderate, quadrate, 

 feebly convex, nearly smooth, sinuato-truncate; elytra cuneate, slightly 

 elongate, only a fifth wider than the prothorax, the striae fine, very shallow 

 and feeble, more shining than the intervals and finely, feebly punctulate; 

 external tibial tooth moderate and at a considerable distance from the base; 

 abdominal plaque broadly, evenly concave, strongly and densely punctate, 

 smooth in basal fourth or more. Length 7.6-8.3 mm.; width 4.6-5.4 mm.

Scutellar stria obsolete basally 11 



11 — Form nearly as in the preceding but smaller and slightly narrower, not so 

 dark and more rufulous above, though obscure, the upper surface more 

 brightly shining than in piceus; beak nearly as in the male of the preceding, 

 the antennal club longer, but little shorter than the funicle; prothorax more 

 elongate, barely wider than long, the converging sides more evenly arcuate 

 from base to the apical tubulation, the latter slightly over a third as wide as 

 the base and broadly arcuate as usual; surface even, with sparse and ex- 

 cessively minute punctulation; basal lobe virtually impunctate, transversely 

 impressed and broadly arcuate, the lateral impressions almost obsolete; 

 scutellum a little wider than long, quadrate, sinuato-truncate, more polished, 

 feebly convex and minutely, sparsely punctate; elytra nearly as in the 

 preceding but narrower, the striae still finer and almost obsolete, the punc- 

 tures infinitesimal and scarcely observable; tibiae nearly similar; basal 

 abdominal plaque nearly flat, finely, rather loosely punctate. Length 7.4 

 mm.; width 4.5 mm. Brazil (Chapada) brunneus n. sp. 



Form almost similar but still narrower, the upper surface nearly as shining but 

 more obscure piceous; beak longer and slightly more slender, fully as long
