Brazilian Baring 307 



medially, with broad smooth median line, gradually somewhat less fine and 

 less remote toward the sides; elytra three-fifths longer than wide, the sides 

 parallel and straight, gradually obliquely rounding behind, the apex narrowly 

 rounded, with reentrant sutural angle, slightly wider than the prothorax 

 and between two and three times as long, the humeri distinctly swollen and 

 slightly prominent; grooves deep, impunctate even at the sides, about a 

 fourth as wide as the very smooth intervals; abdomen very finely, remotely 

 punctulate. Length 3.15-3.3 mm.; width 1.2 mm. Brazil (Santarem). 

 Two specimens laevis n. sp. 



Seventh and eighth grooves attaining the humeri as unimpressed series of de- 

 tached punctures 2 



Seventh and eighth grooves abrupt and deep, like the dorsal grooves, and virtually 

 attaining the humeri; abdomen much more strongly punctate, the sides of 

 the prothorax more abruptly rounded apically than in any other section.. .3 



2 — Body elongate-suboval, moderately narrow; color, lustre and vestiture as in 

 the preceding; beak (o 71 ) as long as the head and prothorax, moderately 

 arcuate and finely, sparsely punctate, or ( 9 ) nearly a fourth longer, more 

 slender and gradually somewhat tapering, almost similarly punctulate, the 

 antenna nearly as in the preceding species; prothorax only a fourth to fifth 

 wider than long, the subparallel and broadly arcuate sides gradually more 

 arcuate anteriorly, but less strongly than in Icevis; punctures nearly similar 

 but closer at the sides and along the base, especially toward the middle; 

 scutellum more elongate; elytra similar in outline but narrower, two-thirds 

 longer than wide, the grooves relatively somewhat coarser, the sparse in- 

 finitesimal punctulation of the intervals barely visible, not obsolete as in 

 Icevis; male abdomen distinctly, not very sparsely punctate on the first two 

 segments, having medially a distinct impression toward base. Length 2.7- 

 2.8 mm.; width 1.0-1.1 mm. Brazil (Chapada — forest). October and 

 November. Two specimens piceolus n. sp. 



Body a little less narrow, similar in color, polished lustre and squamulation of the 

 met-episterna; beak ( 9 ) longer and smoother than in piceolus and a third 

 longer than the head and prothorax, the punctulation very fine and sparse; 

 prothorax larger, a little shorter, fully a fourth wider than long, the sides 

 as in piceolus; punctures much more minute and remote, not so close laterally 

 and not closer along the base; elytra broader, three-fifths longer than wide, 

 parallel, the nearly straight sides rapidly rounding and oblique behind to 

 the similarly narrow apex, as in Icevis; grooves nearly similar; scutellum 

 smaller and much shorter, subquadrate; abdominal punctures basally much 

 more minute and remote than in either sex of piceolus. Length 2.9 mm.; 

 width 1. 15 mm. Brazil (Chapada— forest). October. A single female. 



incomptus n. sp. 



Body smaller, rather less convex, similar in color, lustre and in the squamulose 

 met-episterna; beak (9) much shorter, a little more arcuate, especially at 

 base, not as long as the head and prothorax, minutely, sparsely punctulate 

 and slender as usual; prothorax less than a fourth wider than long, the sides 

 parallel, feebly and subevenly arcuate, more rapidly rounding in about 

 apical fourth to the slightly constricted and very faintly subtubulate apex, 

 of which there is no trace in the preceding; punctures very fine, only half as 

 widely separated as in incomptus, coarser but not closer laterally; scutellum 

 small, feebly impressed, subquadrate, only very little longer than wide; 

 elytra narrower, almost three-fourths longer than wide, less distinctly wider 

 than the prothorax and between two and three times as long, the outline 

 nearly similar but with the humeri more sharply prominent; grooves not so 

 coarse, the intervals smooth; abdomen subimpunctate. Length 2.6-2.7 

 mm.; width 0.85-0.9 mm. Brazil (Santarem). Three examples.
