very fine and feeble, minutely, subobsoletely and remotely punctulate, the 

 sutural not differing from the others; outer inferior tooth of the hind femora 

 rather high but with somewhat blunt apex; abdominal plaque deeply im- 

 pressed, with angulate section, strongly and very densely punctate and 

 conspicuously setulose, the bottom being a narrow smoother gutter; base 

 broadly smooth. Length 8.5 mm.; width 5.6 mm. Brazil (one specimen 

 received from a European dealer and without further indication of locality). 



convexicollis n. sp. 



18 — Base of the pronotum rather deeply impressed at each side of the basal 

 lobe 19 



Base not, or very feebly and obsoletely, impressed at each side of the lobe 20 



19 — Body broadly oval, with the humeri broadly rounded though slightly promi- 

 nent, black, the upper surface highly polished, piceous-black, the pronotum 

 rufo-piceous; beak short, three-fifths as long as the prothorax, thick and 

 straight, thinner and arcuate distally, compressed, closely punctate, more 

 finely above; antennae at the middle, the lateral sulci beyond broad and 

 deep; club thick, oval, nearly as long as the funicle; prothorax a fourth wider 

 than long, the sides evenly, strongly arcuate and converging from base to 

 tubulation; surface very evenly convex, highly polished and smooth; basal 

 lobe narrowly rounded at tip, with a few minute punctules; scutellum small, 

 smooth, flat and quadrate; elytra ovoidal, barely longer than wide, about a 

 fourth wider than the prothorax; striae very fine and subobsolete, minutely 

 and remotely punctate, the sutural gradually rather coarse and deep basally; 

 hind tibial tooth sharply angulate; feebly concave abdominal plaque finely, 

 sparsely punctate. Length 5.0 mm.; width 3.7 mm. Brazil (a single 

 female from a European dealer, labeled cardinatus, but not that species). 



scutellinus n. sp. 



Body smaller and narrower, one of the smallest of the genus, deep black and very 

 highly polished, the pronotum rather bright testaceous, except at apex; 

 beak rather slender, arcuate, nearly four-fifths as long as the prothorax, 

 evenly cylindric, shining and finely, sparsely punctate, the antenna? sub- 

 medial, the club large, as long as the funicle; prothorax but little wider than 

 long, the sides rather strongly converging, broadly, subevenly arcuate from 

 base to tubulation; basal lobe nearly impunctate, narrowly truncate at tip; 

 scutellum wider than long, subquadrate, flat and finely punctate; elytra 

 ovoidal, not longer than wide, nearly a third wider than the prothorax, the 

 humeri broadly rounded though rather prominent, the converging sides 

 thence subevenly arcuate to the narrowly obtuse apex; stria? very fine but 

 distinct, especially behind, the sutural rather coarse; punctures excessively 

 minute and subobsolete; basal abdominal plaque feebly concave, coarsely, 

 loosely punctate; hind tibial tooth fine and very sharp, aciculate at the 

 summit. Length 4.2 mm.; width 2.8 mm. Brazil (Rio de Janeiro). No- 

 vember. A single female teretirostris n. sp. 



20 — Front with a moderate perforate fovea at each side near the eye. Body 

 very small and rhombic-oval, highly polished and smooth, very convex, 

 deep black, the pronotum bright rufous except at tip; beak short and very 

 thick, slightly arcuate and tapering, two-thirds as long as the prothorax, 

 compressed, closely punctate, the punctures small, slightly larger at the sides; 

 antenna? submedial, the lateral gutters beyond them broad; club as usual; 

 prothorax barely wider than long, the strongly converging sides evenly and 

 moderately arcuate from base to tubulation; basal lobe short, rather abrupt, 

 the apex sinuate medially, no punctures visible except at tip of the lobe; 

 scutellum truncate, with rounded angles, slightly wider than long, perfectly 

 flat and smooth, the sides converging from near apex to the base; elytra 

 somewhat distinctly longer than wide, cuneiform, with feebly arcuate sides,
