about half their width, and is very short, medially impressed and 

 minutely bilobed behind them. The legs are moderate, with un- 

 armed femora, the anterior more inflated than the others, the tibiae 

 straight, with very strong curved inner spur at apex, the tarsi rather 

 slender, with very moderately dilated third joint, the fourth very 

 long, much exceeding the entire basal part and with two notably 

 large diverging claws. The prothorax is moderately tubulate at 

 apex, the basal lobe very small and feeble, the scutellum flat, free, 

 as long as wide and obtrapezoidal and the elytra rather deeply but 

 moderately grooved. The greatly exposed pygidium is gently 

 sloping and is shorter and much more obtusely rounded behind in 

 the male than in the female. There are three species at hand 

 as follows: 



Pronotum with a mixture of larger and finer sparse punctures, the larger bearing 

 long stiff erect setae. Body elongate-oval, very moderately convex, shining and 

 deep black throughout; beak (cf) only as long as the prothorax, rather 

 thick, strongly and closely punctured, gradually tapering, thin and finely, 

 sparsely punctate distally, bristling with short and very coarse, fulvous setae 

 except apically, and very feebly arcuate; antennae piceous; prothorax fully 

 a fifth longer than wide, the sides broadly and distinctly arcuate from base 

 to tubulation, which is three-sevenths as wide as the base; punctures strong 

 and longitudinally subconfluent at the extreme sides, nearly all fine and 

 sparse medially; median smooth line distinct, except at base and apex; 

 elytra three-fifths longer than wide, with oblique and broadly arcuate sides 

 and individually rounded apices, a fourth or fifth wider than the prothorax 

 and two-thirds longer, the humeri feebly tumid; posterior tumidity very 

 moderate; grooves rather narrow, a little coarser and more punctate later- 

 ally; intervals with moderate distant punctures, bearing short setae, inter- 

 mingled with minute and confused punctures medially; pygidium convexly 

 sloping, wider than long, very broadly rounded at apex and strongly and 

 closely but discretely punctate; male abdomen smooth, the basal segment 

 rather strongly punctured and with a simple median impression. Length 

 6.0 mm.; width 2.35 mm. Brazil (Santarem). One specimen. 



binarius n. sp. 



Pronotum finely, sparsely and almost uniformly punctate, the punctures be- 

 coming in great part rather cOarse and close and bearing very short, fine 

 erect setae at the extreme sides 2 



2 — Elongate-oval, rather depressed, deep black and shining; beak (9) only a 

 little shorter than the body, feebly arcuate and very slender, slightly flattened, 

 polished and impunctate, becoming rather rapidly thick and with moderate 

 though deep, notably sparse punctures bearing very short setae, in rather 

 less than basal third; antennae piceous, at the end of the thickened part of 

 the beak, much longer than in the male of binarius; prothorax nearly a 

 sixth longer than wide, subinflated basally, slightly widest before the base, 

 the sides broadly, subevenly arcuate and converging, the tubulation three- 

 sevenths as wide as the base; median smooth area as in the preceding; basal 

 lobe minute, short and truncate, somewhat as in binarius; elytra barely 

 more than one-half longer than wide, a fifth wider and four-sevenths longer 

 than the prothorax, similar in form and sculpture to the preceding; pygidium 

 long, triangular, with feebly arcuate sides and very gradually sloping surface, 

 almost as wide as long and moderately and discretely punctate, feebly tumid
