Brazilian Baring 87 



shorter (c?), somewhat flattened distally as usual; antennae medial; front 

 concave between the eyes; prothorax fully three-fourths wider than long, 

 the converging sides rounded basally, straighter apically, the truncate apex 

 three-sevenths as wide as the base; surface with minute sparse punctulation, 

 becoming a little more evident toward the obtuse and strongly punctate 

 edges; basal lobe broad and gradual, rounded; scutellum as long as wide, 

 arcuately triangular; elytra obtusely oval, about as long as wide, slightly 

 wider than the prothorax, the humeral callus longitudinally somewhat 

 prominent; grooves smooth, 7 and 8 not extending to the humeri; intervals 

 very smooth, the second much wider than the third and more than twice as 

 wide as the first; hind femora but slightly oval, subparallel, moderately and 

 loosely punctate, with grooved surface inferiorly. Length 3.8-3.9 mm.; 

 width 2.45-2.6 mm. Brazil (Santarem). Three specimens, .atrolucens n.sp. 



Body smaller in size, very regularly oval, deep black and shining throughout, 

 strongly and closely punctured beneath, except on the abdomen; beak a 

 little longer than the head and prothorax, finely punctate, carinulate above 

 basally, the front between the eyes smooth and concave; prothorax one- 

 half wider than long, the sides converging and strongly, very evenly arcuate 

 from base to apex — this form unusual in the genus; truncate apex much 

 less than half as wide as the base, the basal lobe very gradual but only 

 narrowly rounded at tip; surface smooth, the fine punctulation nearly 

 obsolete, gradually evident toward the sides; scutellum fully as long as wide, 

 triangular, with only feebly arcuate sides; elytra as long as wide, very 

 little wider than the prothorax, parabolic, the humeri but slightly swollen; 

 grooves abrupt but only moderately deep, finely, remotely punctulate; 

 intervals minutely, sparsely punctulate, the second but little wider than the 

 third; femora moderate, with longitudinally anastomosing punctures. 

 Length 2.8 mm.; width 1.8 mm. Brazil (Para). Desbrochers des Loges. 

 One specimen ellipticus 



4 — Form rather broadly oval, polished and deep black; under surfaces with the 

 punctures rather smaller than in the preceding and less close-set; beak 

 feebly arcuate, rather notably longer than the head and prothorax, finely 

 punctate; eyes large, narrowly separated; prothorax shorter, fully three- 

 fourths wider than long, the side strongly converging, subevenly and very 

 moderately arcuate from base to apex, the latter, as usual, rectilinearly 

 truncate, about three-sevenths as wide as the base, the lobe smaller, less 

 gradually formed, rather narrowly rounded at tip; surface very smooth, the 

 punctulation obsolete; scutellum smaller, rather minute, as wide as long, 

 arcuately triangular; elytra scarcely as long as wide, evidently wider than 

 the prothorax, obtusely parabolic, the broadly rounded humeri feebly and 

 longitudinally swollen above; strise very abrupt and deep, smooth, the 

 intervals very smooth, scarcely even micro-punctulate; hind femora loosely 

 punctate, becoming longitudinally rugulose beneath. Length 2.35-2.65 

 mm.; width 1. 45-1. 65 mm. Brazil (Entre Rios). September. Nine speci- 

 mens intermedius n. sp. 



Form a little less broadly oval, nearly similar in color, lustre and sculpture; 

 eyes large, very narrowly separated medially; beak feebly arcuate, not very 

 slender, notably longer than the head and prothorax, the latter less abbre- 

 viated, barely three-fifths wider than long, the sides evenly and moderately 

 arcuate, but less convergent, from base to apex, the latter narrower, only 

 two-fifths as wide as the base; basal lobe and surface nearly similar; scu- 

 tellum even more minute, barely as wide as long, obtusely ogival; elytra 

 almost similar but more obtusely rounded behind, and with the humeri very 

 slightly more swollen and prominent; groove-like strise deep and smooth, 

 a little finer than in the preceding; intervals smooth and flat; hind femora
