Brazilian Baring 67 



at the middle of its rounded contour; scutellum nearly similar, but more 

 truncate behind; elytra more evidently longer than wide, and, at the broadly 

 rounded humeri, more distinctly wider than the prothorax; stria; extremely 

 fine, but rather more evident than in the preceding, impunctate; under 

 surface and legs nearly similar, the very acute outer tooth of the hind tibia; 

 still larger and higher. Length 3.5 mm.; width 2.5 mm. Brazil (Chapada). 



March. One specimen convergens n. sp. 



Form nearly as in convergens but stouter, the sides of the elytra less arcuate than 

 in evanescens; outline rhombic-oval; beak (cf) rather thick, feebly arcuate 

 and compressed, three-fifths as long as the prothorax, rather distinctly 

 tapering distally, strongly but not very coarsely punctate throughout, the 

 upper surface with fine and smoother line, or ( 9 ) three-fourths as long as 

 the prothorax, slightly less thick and not quite so tapering; antennal club 

 three-fifths as long as the funicle; prothorax with the surface in profile 

 rather strongly, subevenly arcuate, scarcely a fifth wider than long, the 

 converging sides subevenly arcuate; basal lobe obtusely rounded, with a 

 very minute and feeble median sinus; scutellum transversely suboval, 

 nearly smooth, feebly convex; elytra slightly elongate, but little wider than 

 the prothorax, rapidly parabolic, with very moderately arcuate sides and nar- 

 rowly rounded apex, the humeri very broadly rounded; discal stria extremely 

 fine, feeble and subobsolete; posterior part of the mes-epimera impunctate; 

 hind femora strongly, sparsely punctate, the tibial tooth high, large and 

 very acute; first ventral tumid, evenly convex and unimpressed medially, 

 very coarsely, densely sculptured. Length 3.7-3.9 mm.; width 2.65 mm. 



Brazil (Santarem). Two specimens gulosus n. sp. 



Form nearly similar but slightly less obese and smaller in size; beak nearly 

 similar, but with more pronounced transverse basal impression, the antennal 

 club nearly similar, but rather more gradually pointed; prothorax similar, 

 the basal sublobar impression more distinct though feeble; lobe less broadly 

 rounded, the small sinus similar; scutellum nearly flat, smooth, not so 

 distinctly wider than long, rounded; elytra more distinctly elongate, nearly 

 similar in outline, but with the apex still more narrowly rounded; discal 

 striae almost completely obsolete, not evidently traceable, but with evidences 

 at base and apex as usual; mes-epimera and under surface almost similar, 

 the scabrous first ventral even more conspicuously, evenly tumid at the 

 middle; legs nearly similar, even less closely punctate. Length 3.0 mm.; 



width 2.15 mm. Brazil (Santarem). One specimen amnicola n. sp! 



6— Body oval, but faintly subrhombic; beak short, rather thick, feebly arcuate, 

 narrowing distally, four-sevenths as long as the prothorax, strongly com- 

 pressed, finely, not densely punctate, still more finely and very inconspic- 

 uously above, the transverse basal impression distinct; antenna; medial, the 

 club slightly smaller and narrower, but little more than half as long as the 

 funicle; prothorax in profile much more rapidly sloping near the apex, 

 more than a fourth wider than long, the very strongly converging sides 

 moderately and evenly arcuate, the subtubulate apex slightly more than 

 a third as wide as the base; surface extremely smooth and polished above 

 and below; basal lobe broadly rounded, with a very minute and feeble sinus; 

 scutellum very small, quadrate, feebly impressed centrally; elytra slightly 

 elongate, ogival, with evenly and rather strongly rounded sides and narrowly 

 rounded apex, across the feebly prominent and rounded humeri about a 

 sixth wider than the prothorax; discal striae barely traceable, except at base 

 and apically; mes-epimera, very exceptionally, entirely smooth, with faint 

 traces of punctures only anteriorly; hind femora somewhat clavate, unusually 

 short and rather finely, sparsely punctate, the tibial tooth triangular and 

 acute. Length 3.0 mm.; width 2.1 mm. Brazil (Santarem). One male 

 example fiebilis n. sp.
