Brazilian Barin^e 6i 



propleura smooth but punctate along the base; abdomen sparsely punctate; 

 tibiae slender, rounded externally at base, without trace of angulation. 

 Length 2.65 mm.; width 1.5 mm. Brazil (Santarem). One specimen. 



vernix n. sp. 

 9 — Outline subevenly oval, shining, deep black in color, the prothorax above and 

 beneath bright rufous; beak rather thick, moderately arcuate, compressed 

 and strongly, densely sculptured, less coarsely but in great part strigosely 

 above, three-fourths as long as the prothorax, the antennae medial; head 

 minutely, remotely punctate, piceous in color; prothorax about a fifth 

 wider than long, the sides feebly converging and slightly arcuate, rapidly 

 rounding in about apical third to the strong tubulation, which is much less 

 than half as wide as the base; surface throughout with distinct sparse 

 punctures, bearing short erect yellowish setae; basal lobe moderate, rounded, 

 unimpressed; scutellum very small, oblong, deeply canalate except at base; 

 elytra regularly and obtusely parabolic, a fifth longer than wide and a fifth 

 wider than the prothorax, the subapical prominences moderate; humeri 

 obliquely rounded, scarcely prominent; grooves very coarse, deep and abrupt, 

 punctured along the bottom, equal throughout; intervals flat, each with a 

 single series of distinct and well-spaced punctures, bearing rather long erect 

 silvery setae; under surface strongly and closely, the legs coarsely and 

 rugosely, punctured; tibiae externally toward base not angulate, but with a 

 series of small erect acute spines; claws arcuate, slender, long and widely 

 separated. Length 2.7 mm.; width 1.4 mm. Brazil (Chapada — forest). 

 October. One specimen setulosus n. sp. 



These species hold together in general structure and habitus 

 very well, and seem to constitute a natural generic group. 



Bonomius n. gen. 



In its bright metallic coloration, the type of this genus stands 

 apart from the rest of the tribe and forms a very striking exception 

 to anything hitherto known, so far as I can discover; it may be 

 described as follows: 



Bonomius aeneoviridis n. sp. — Rather elongate, rhombic-suboval, very smooth 

 and polished throughout above and beneath, bright greenish-aeneous throughout, 

 the legs slightly more greenish; beak thick, fully as long as the prothorax, moder- 

 ately and evenly arcuate, evenly cylindric, distinctly but irregularly punctate, 

 minutely and sparsely above, not impressed at base; antennae submedial, the 

 club large, oval, compact and fully as long as the funicle, finely, very densely 

 pubescent, the sutures evident; lateral grooves beyond the antennae deep more 

 than half way to the apex; mandibles thick, decussate; head rather strongly, 

 closely punctured, the frontal fovea distinct; prothorax but little wider than 

 long, the sides rather strongly converging, broadly and evenly arcuate from base 

 to the broad tubulation, which is half as wide as the base; surface very smooth 

 and impunctate; basal lobe small, narrowly rounded, the lateral impressions 

 shallow but somewhat evident; scutellum rather small, smooth, as wide as long, 

 narrowed basally; elytra three-sevenths longer than wide, two-fifths wider than 

 the prothorax, parabolic, but with very feebly arcuate sides, the humeri rather nar- 

 rowly rounded and laterally prominent; striae extremely fine and barely traceable, 

 with fine and rather distant punctures, 1 and 2 elongate-foveiform at base, 1-3 deep 

 and groove-like near the apex, 9 and 10 moderately coarse, fine basally; intervals 

 wide, flat, impunctate; abdomen shining and smooth, impunctate, transversely
