Brazilian Baring 4°9 



sides and strongly rounded, only moderately obtuse tip, evidently wider 

 than the prothorax and scarcely twice as long; grooves very fine, not coarser 

 basally and barely perceptibly so apically; abdomen as usual in this section, 

 minutely, sparsely punctulate and evenly convex in both sexes; sternal 

 punctures strong but well separated. Length 2.1-2.4 mm.; width 0.9- 

 1.15 mm. Brazil (Chapada— forest). August and October. Four speci- 



mens fusiformis n. sp. 



7 _Body oblong-oval, polished, black throughout; beak in the type moderately 

 slender, evenly, rather strongly arcuate, feebly tapering, rather dull, com- 

 pressed' and strigato-punctured at the sides and evidently longer than the" 

 head and prothorax, the separating impression scarcely traceable; prothorax 

 somewhat less than one-half wider than long, the sides strongly, subevenly 

 arcuate, becoming straighter and feebly diverging basally, oblique and 

 scarcely at all sinuate apically, the tubulation obsolete, the surface slightly 

 impressed, however, apically; apex not quite half as wide as the base; surface 

 convex, more strongly just behind the middle, very smooth and without 

 discernible punctulation; elytra obtusely oval, a fourth longer than wide, 

 the slightly oblique sides but just visibly arcuate, the apex broad and rounded, 

 at the very feebly tumid humeri slightly wider than the prothorax, evidently 

 more than twice as long; grooves extremely fine, not coarser basally, but 

 somewhat so and impressed apically toward the suture; intervals wide and 

 very smooth; sterna loosely punctate. Length 2.3 mm.; width 1.18 mm. 



Brazil (Santarem). One specimen, possibly female elotus n. sp. 



8_Outline oblong-oval, the surface shining and convex, smooth, deep black 

 throughout; beak (d") rather strongly, evenly arcuate, equally subcylindnc, 

 finely, loosely strigato-punctate, not separated by an obvious depression 

 and but little longer than the head and prothorax, or ( 9 ) almost similar 

 but longer, not quite so strongly, though evenly, arcuate, and very little 

 more slender, a third long'er than the head and prothorax, the latter evenly 

 and moderately convex in profile, two-fifths wider than long, the sides just 

 visibly converging and nearly straight, strongly, evenly rounded beyond the 

 middle to the short, very gradual and feebly defined tubulation, which is not 

 quite half as wide as the base; surface with the remote infinitesimal punc- 

 tulation scarcely discernible, the basal lobe truncate medially; elytra with 

 the sides slightly oblique and feebly arcuate, the apex strongly but broadly 

 rounded, a fourth or fifth longer than wide, slightly wider than the prothorax 

 but scarcely twice as long, the humeri distinctly swollen; grooves fine and 

 shallow, faintly subcrenulate, broadly, feebly impressed suturally at apex, 

 not coarser basally; intervals smooth; pygidium small, transverse and 

 densely punctate. Length 2.0-2.15 mm.; width 1 .0-1.15 mm. Brazil 



(Chapada— forest). November. Two specimens nugator n. sp. 



Outline somewhat similar but much larger in size and stouter, rather more convex, 

 oblong-oval, shining, deep black throughout; beak (9) longer, somewhat 

 more than half as long as the body, evenly but rather feebly arcuate and 

 finely, somewhat closely sculptured; prothorax large, not quite one-half 

 wider than long, the sides feebly converging and just visibly arcuate, rapidly 

 evenly and strongly arcuate beyond the middle to the rather definite, though 

 gradually formed, short tubulation, which is nearly half as wide as the base; 

 punctures minute and sparse, becoming rather strong though not close at 

 the extreme sides; basal lobe truncate, the scutellum slightly free or at 

 least not very closely fitted; elytra broadly oval, scarcely a fifth longer than 

 wide, the feebly arcuate sides a little more oblique than in the preceding, 

 slightly wider than the prothorax and not quite twice as long, the apex 

 relatively somewhat less obtuse; striation similar, the fine striae remotely 

 and feebly crenulate. Length 2.5 mm.; width 1.35 mm. Brazil (Chapada).
