apically deflexed in the type, somewhat more than half as long as the body 

 in sedulus, a little less than half in the present species. Length 3.8-4.2 

 mm.; width 1.85-2.0 mm. Brazil (Santarem). A single pair. 



longipes n. sp. 



4 — Form subrhombic-oval, rather strongly shining and deep black, convex; beak 

 (c?) strongly arcuate, rather thick, not coarsely but strongly sculptured, 

 very evenly tapering throughout and a little longer than the elytra; antennae 

 slender, piceous, the second funicular joint subcylindric and nearly three 

 times as long as wide, the club scarcely longer than the four preceding joints; 

 prothorax scarcely more than a fifth wider than long, the sides broadly, 

 subevenly arcuate, becoming subparallel posteriorly, the tubulation half as 

 wide as the base; punctures coarse, well separated at the sides, the median 

 line and squamules as in the preceding species; scutellum quadrate, with a 

 few squamules, those of the elytral base and medial chevron nearly as in 

 sedulus; elytra rather more than a fourth longer than wide, only about two- 

 thirds longer than the prothorax, the oblique sides very moderately arcuate; 

 apex narrowly though obtusely rounded; groves deep, half as wide as the 

 intervals or somewhat less, the punctures of the interstitial series strong and 

 well separated; abdomen convex, sparsely punctured and unmodified in the 

 male, the prosternal processes long and very slender, longer than the head 

 and prothorax, obscure testaceous and so strongly curved that in apical half 

 they are perpendicular to the basal part. Length 3.25 mm.; width 1.4 mm. 

 Brazil (Santarem). One male curvatus n. sp. 



Form narrower, less rhombic and with shorter prothorax and less oblique sides of 

 the elytral chevron, deep black, the sculpture and vestiture nearly as in the 

 preceding, the beak not quite so long, but otherwise very nearly similar, the 

 antennae evidently less elongate; prothorax about a third wider than long, 

 the strongly arcuate sides gradually parallel basally, the apical tubulation 

 much shorter and more feebly marked, distinctly wider, and with larger 

 head in the female, where it is half as wide as the base; punctures rather 

 coarse, closer at the sides than in the preceding; smooth median line distinct; 

 surface similarly feebly gibbous; scutellum subquadrate, smooth; elytra a 

 fourth longer than wide, less (9), the sides less oblique and more arcuate 

 than in the preceding, the coarse sculpture and scanty white squamules 

 nearly similar, except that the loose median chevron is broader, with its 

 sides less oblique; abdomen strongly convex, distinctly but loosely punctate 

 in the male, the prosternal spines 'short, very slender, almost semicircularly 

 curved and scarcely half as long as the tibiae in the type. Length 2.65-3.0 mm. ; 

 width 1. 2-1. 35 mm. Brazil (Santarem). A single pair. . breviusculus n. sp. 



5 — Body small, almost evenly oval, moderately convex above, strongly so beneath 

 as usual, deep black and rather strongly shining, the squamules narrow and 

 white, very sparse on the pronotum sublaterally and at the elytral base, 

 more condensed near the scutellum and forming short loose single lines on 

 intervals 4-6 or thereabout, from the middle to apical third, fine and sparse 

 in the strong loose punctures beneath, but coarser and dense on the met- 

 episterna, the abdomen very sparsely punctulate and micro-squamulose; 

 beak slender, strongly arcuate and three-fifths as long as the body, cylindric, 

 feebly tapering and somewhat finely, loosely sculptured; antennae near 

 basal third, black, the first funicular joint as long as the next two, the club 

 oval and as long as the preceding five joints; prothorax nearly two-fifths 

 wider than long, the feebly converging sides a little more arcuate anteriorly, 

 the tubulation more than half as wide as the base; extreme sides rugosely 

 and coarsely punctate, all the rest very finely and remotely punctulate; 

 basal lobe sinuate at apex; scutellum small, obtrapezoidal and feebly im- 

 pressed; elytra oval, a fourth longer than wide, not twice as long as the
