intervals in basal half, also intervals 4-6 in short lines behind the middle, 

 whiter and dense beneath, but very sparse and inconspicuous on the meso- 

 sternum and side-pieces and prothorax beneath; beak nearly similar in the 

 sexes, strongly arcuate (o 71 ), a little less so (9), dull, slender, two-thirds as 

 long as the elytra; antennae submedial; prothorax short, fully two-fifths 

 wider than long, the somewhat strongly converging sides broadly and sub- 

 evenly arcuate, the truncate apex more than half as wide as the base; punc- 

 tures rather coarse and very close, though more or less separated; scutellum 

 small, feebly squamulose; elytra rather rapidly parabolic, a fourth to fifth 

 longer than wide, somewhat more than twice as long as the prothorax, the 

 grooves moderate, deep; male with the abdomen distinctly impressed medio- 

 basally, the prosternal spines erect, very short, scarcely as long as the thick- 

 ness of the femur, though much more distinct than in devincta. Length 

 2.3-2.6 mm.; width 1. 2-1 .35 mm. Brazil (Entre Rios). September. Two 

 specimens : derisor n. sp. 



Form narrowly oval, the size very small; surface dull; color piceous-black, the 

 legs, beak and antennae rufescent; slender pale squamules above sparsely 

 aggregated in three pronotal vittae and, on the elytra, loose, but more evident 

 on the second interval at apex and in basal half and on 4-6 in short discal 

 lines, that of the fourth rather long — from before the middle to apical fourth, 

 the scales whiter and close beneath, sparser on the prothorax; beak in the 

 type slender, strongly arcuate, only three-fifths as long as the elytra, punctate 

 and sparsely squamose in part; antennae medial, rufous, the oval club fully 

 as long as the four preceding joints; prothorax conical, a fourth wider than 

 long, the converging sides very feebly arcuate medially, the truncate apex 

 more than half as wide as the base; punctures strong, moderately separated 

 by the opaque interstices; scutellum small, rather closely squamose; elytra 

 elliptic, a third longer than wide, distinctly more than twice as long as the 

 prothorax, the grooves moderate but deep as usual; abdomen in the type 

 feebly impressed medially at base, the presternum wholly without spicules, 

 the anterior coxae narrowly separated. Length 2.0 mm.; width 0.85 mm. 

 Brazil (Chapada). October. One specimen ancilla n. sp. 



11 — Body small, not stout, somewhat shining and piceous throughout; slender 

 pale squamules sparsely aggregated on the pronotum sublaterally toward 

 base, on the elytra subevenly and loosely distributed along the strial intervals, 

 on some of them in single lines, beneath small, slender, white and rather 

 sparse; beak (o 71 ) strongly arcuate, cylindric and with the punctures well 

 separated, not two-thirds as long as the elytra; antennae moderate, piceous, 

 medial; prothorax a third wider than long, the converging sides straight for 

 three-fifths, there rounding to the tubulation, which is not quite half as 

 wide as the base; punctures rather strong, narrowly separated, the smooth 

 median line narrow, entire and well defined; scutellum small, quadrate, 

 uneven and partially squamulose; elytra convex, parabolic, with somewhat 

 narrowly rounded tip, more than a fourth longer than wide, relatively wider 

 at base than in the few preceding species and about a fourth wider than the 

 prothorax, much more than twice as long, the grooves abrupt and deep; 

 intervals finely, sparsely and confusedly punctate; male with the prosternal 

 spines slender, straight, oblique and not quite two-fifths as long as the 

 prothorax in the type. Length 2.35 mm.; width 1.3 mm. Brazil (Entre 

 Rios). September. One specimen tubulifera n. sp. 



IV — -Form elongate, subrhombic, black, with slender and unusually elongate 

 piceo-rufous legs; ground squamules of the elytra fine and blackish, the 

 narrow white sutural vitta abruptly ending at apical fifth; scutellum well 

 developed and densely albido-squamose ; squamules of the entire under surface 

 lustrous and whitish, very close; beak evenly, rather strongly arcuate, very
