more slender, strongly, evenly arcuate, two-thirds as long as the elytra, 

 smooth and gradually feebly tapering beyond the antennae, which are long, 

 slender, piceous, near apical fourth (d 71 ), or medial ( 9 ); prothorax as long 

 as wide (c 71 ), a sixth wider ( 9 ); inflated basally, thence gradually narrowed 

 to the tubulation, which is defined by a distinct impressed line; surface 

 similar; scutellum and elytra subsimilar; surface throughout above very 

 faintly alutaceous; pygidium (o 71 ) similar but less coarsely punctate, or ( 9 ) 

 almost exactly similar but smaller; medio-basal abdominal impression of 

 the male differing in being loosely clothed throughout, except at base, with 

 long slender brownish setae. Length 10. 2-1 1.0 mm.; width 4.2 mm. Brazil 

 (Santarem). Three specimens longipes n. sp. 



6 — Body nearly as in all the preceding in color, lustre and sculpture, except that 

 the black legs have the femora distinctly though nubilously rufous medially; 

 beak (cf) not quite so long, a little less than half as long as the body, finely, 

 loosely punctate, nearly straight, arcuate beyond the antennae as usual, or 

 ( 9 ) differing somewhat less from that of the male than in the preceding, 

 though evidently shorter, evenly and rather strongly arcuate, the smooth 

 part beyond the antennae more abruptly narrowed; under surface (cf) only 

 very feebly crenulate and with a shorter and sparser fringe; antennae (0 71 ) 

 slender, at apical third, the outer funicular joints but little wider and only 

 very slightly transverse, the club barely longer than the five preceding joints, 

 more oval and equally divided by the sutures, or ( 9 ) having more transverse 

 distal funicular joints and slightly shorter club; prothorax very slightly 

 shorter than wide, more evidently ( 9 ), less inflated basally, the sides only a 

 little more arcuate anteriorly, the surface similar, the scutellum and elytra 

 also nearly as in the preceding species; pygidium differing much more in the 

 sexes, large, only one-half wider than long and tumid along the middle (o 71 ), 

 or smaller, shorter, flatter and more densely punctured ( 9 ) ; medio-basal 

 abdominal impression (o 71 ) larger, more broadly oval, and with only the 

 extreme sides sparsely setulose. Length 8.6-8.85 mm.; width 3.4-3.65 mm. 

 Brazil (Amazon Valley). Desbrochers des Loges. Two specimens. 



lucidus n. sp. 



Body still smaller and narrower, deep black, with similar elytral maculae, the 

 legs deep black; beak (d") still shorter, evidently less than half as long as 

 the body, not crenate but briefly and loosely fimbriate beneath; antennae 

 near three-fifths, piceo-rufous, the outer funicular joints but very slightly 

 enlarged or transverse, the club long, cylindric-oval, nearly as long as the 

 six preceding joints, its basal segment much longer than the second, obconic 

 and truncate at base as usual; prothorax a fifth or sixth wider than long, the 

 converging sides nearly straight, gradually broadly rounding anteriorly, the 

 tubulation defined by a very fine and feeble impressed line; sculpture, lobe, 

 scutellum and elytra nearly as in the other species; pygidium (o 71 ) smaller 

 and much shorter than in the preceding, nearly twice as wide as long, the 

 deeply punctate surface not medially carinulate as in lucidus, but discally 

 tumid medially beyond the middle; medio-basal abdominal impression of the 

 male much feebler, narrower and shallower than in any of the preceding, 

 with a few fine decumbent sublateral yellowish setae. Length 7.3 mm.; 

 width 3.0 mm. Brazil (Para). A single specimen parensis n. sp. 



7 — Legs rufous, the femora slightly shaded at base and apex; four elytral red 

 spots brighter than usual. Oblong-oval, shining, the body deep black, 

 excepting the red elytral maculae; beak ( 9 ) two-thirds as long as the elytra, 

 strongly and evenly arcuate, smooth, but only very feebly and gradually 

 tapering beyond the antennae, which are just visibly beyond the middle, 

 piceous, with narrow and gradually pointed club, the outer funicular joints
