middle, slender and feebly tapering, smooth and finely, sparsely punctate, 

 the antennae moderate, piceous, just visibly behind the middle; prothorax 

 transverse, not quite one-half wider than long, the strongly arcuate sides 

 gradually subparallel basally, the completely non-tubulate truncate apex half 

 as wide as the base; punctures moderate but deep, separated by nearly 

 twice their widths, with a smooth median line; elytra elliptic, a fourth longer 

 than wide, twice as long as the prothorax, the grooves deep; intervals finely, 

 sparsely and confusedly punctate. Length 3.0 mm.; width 1.5 mm. Brazil 



(Chapada). November. One female bucolica n. sp. 



II — Size moderately small, the outline broadly oval 2 



Size more or less minute, more elongate-oval 3 



2 — Body subevenly oval, black and somewhat shining, with only feebly prominent 

 humeri; scales above yellowish-white, very slender and not dense, though 

 uniform throughout and not concealing the integument, larger, denser and 

 whiter beneath; beak (o 71 ) as long as the elytra and strongly, evenly arcuate, 

 moderately slender, rather closely punctate and minutely squamulose basally, 

 or ( 9 ) a little longer, somewhat more narrowed distally, even more strongly, 

 evenly arcuate and smoother; antennae moderately long, behind the middle 

 in both sexes; prothorax nearly one-half wider than long, the sides moder- 

 ately converging, becoming more arcuate beyond the middle to the gradual 

 truncate tubulation, which is less than half as wide as the base; punctures 

 strong and very close, but not in mutual contact; elytra parabolic, nearly a 

 fourth longer than wide, very nearly twice as long as the prothorax, the 

 sutural angle at apex not reentrant; grooves deep, moderate, the intervals 

 finely, confusedly and loosely punctate; male with very feeble abdominal 

 characters, the prosternal spines black, slender, as long as the thickness of 

 the beak to twice as long. Length 2.7-3.0 mm.; width 1. 35-1 .65 mm. 



Brazil (Santarem). Four specimens amnicola n. sp. 



Body smaller and not quite so broadly oval, piceous-black and feebly shining, 

 the legs rufescent; scales above very slender, nearly white, not very closely 

 distributed but uniform, similarly decumbent throughout, as in the others 

 of this group; beak (9) much shorter, thinner and less strongly arcuate 

 than in the preceding, scarcely two-thirds as long as the elytra, slender, 

 piceous and smooth, punctate and squamulose at the sides basally; antennae 

 obscure rufous, moderately long, inserted at the exact middle; prothorax 

 only a fifth or sixth wider than long, the sides feebly, subevenly arcuate to 

 the gradual tubulation, which is half as wide as the base; punctures very 

 moderate and close but evidently separated; elytra similar in form but more 

 narrowly parabolic, a fourth longer than wide, but distinctly less than twice 

 as long as the prothorax; grooves deep, moderate, the intervals rather finely 

 and loosely punctate. Length 2.6 mm; width 1.25 mm. Brazil (Chapada 



— forest). May. A single female specimen sectator n. sp. 



Body somewhat broadly oval and strongly convex, feebly shining and piceous, 

 the legs and beak blacker; squamules above notably long and slender, 

 yellowish, evenly distributed but not very dense; beak (o 71 ) cylindric, very 

 strongly, evenly arcuate and almost as long as the elytra, longitudinally 

 furrowed at the sides and punctate basally; antennae piceous, moderately 

 long, with well developed and elongate-oval club, inserted just behind the 

 middle, the scape extending only four-sevenths the distance to the eye, the 

 latter only moderate in size; prothorax transverse, about four-sevenths 

 wider than long, the sides parallel and straight not quite to the middle, 

 then oblique and feebly arcuate to the truncate apex, which is distinctly less 

 than half as wide as the base; punctures rather strong and evidently sepa- 

 rated; elytra broad, obtusely parabolic, without reentrant sutural angle, 

 only about a fifth longer than wide, but distinctly more than twice as long
