middle, then broadly and strongly rounding to the tubulation, which is 

 fully three-sevenths as wide as the base, almost impunctate, piceous-black 

 as usual; basal lobe smooth, subevenly rounded; scutellum moderate, 

 transverse, smooth, even, narrower at base than at apex; elytra not quite as 

 long as wide, much wider than the prothorax and nearly three-fourths longer; 

 grooves notably coarse, nearly smooth, the second and third not attaining 

 the base; femora coarsely, closely punctate; basal abdominal segment (9) 

 convex, densely and strongly punctate, with a very deeply impressed median 

 line; prosternal canal broad, deep and abrupt. Length 4.65-4.75 mm.; 

 width 3.15-3.3 mm. Brazil (Rio de Janeiro). November. Two female 

 specimens decorus n. sp. 



Color piceous-black, with similarly bright rufous prothorax; form nearly similar 

 but stouter, with relatively rather smaller prothorax and somewhat less 

 prominently rounded median part of the elytral flanks; beak and antennae 

 almost similar; prothorax shorter, fully three-fifths wider than long, the 

 sides becoming more parallel in nearly basal half, more oblique but similarly 

 arcuate anteriorly; tubulation and basal lobe similar; scutellum a little more 

 transverse, not so evidently narrowed at base and with the surface broadly, 

 feebly concave; elytra not quite so abbreviated, fully as long as wide, rather 

 more narrowly rounded at apex; grooves almost similar, but with the sutural 

 more strongly, catenulately punctate; punctures of the inferior surface 

 coarser, those of the femora not quite so coarse and more separated; first 

 ventral ( 9 ) similar, except that the slopes of the median sulcus are steeper 

 and more punctate anteriorly. Length 5.0 mm.; width 3.6 mm. Brazil 

 (Espirito Santo). H. Rolle. One female specimen divisus n. sp. 



Color throughout as in the preceding; body smaller in size, stout; beak (9) 

 thick, arcuate, strongly sculptured and rather longer than the head and 

 prothorax, the antennae nearly similar; prothorax rather shorter, almost 

 two-thirds wider than long, the sides subparallel and broadly arcuate, 

 becoming gradually more rounded and then strongly converging anteriad, 

 the tubulation about two-fifths as wide as the base, the basal lobe smooth, 

 sinuato-truncate at tip, the lateral impressions small; scutellum very moder- 

 ate, strongly transverse, sinuato-truncate and smooth; elytra about as long 

 as wide, not so notably wider than the prothorax as in the two preceding, 

 the humeri not quite so prominent, three-fourths longer than the prothorax; 

 grooves rather coarse and deep, smooth, not quite attaining the base; under 

 surface coarsely punctate, the femora strongly and somewhat closely; first 

 abdominal segment ( 9 ) rather convex but shining and sparsely, though 

 coarsely, punctate, the median impressed line deep but broad and mucrf less 

 abrupt or definite than in the preceding. Length 3.7 mm.; width 2.65 mm. 

 Brazil (Rio de Janeiro). November. One female example. . laetabilis n. sp. 



45 — Sides of the prothorax strongly rounding anteriorly from rather beyond the 

 middle; elytra grooved. Body dee'p black, the prothorax reddish-yellow; 

 beak arcuate, moderately slender, closely, confusedly sculptured at the sides 

 basally, elsewhere finely and rather sparsely punctate, as long as the elytra; 

 antennae just behind the middle, the first funicular joint rather elongate, 

 subequal to the next two, the second twice as long as wide, the club as long 

 as the preceding five joints; prothorax one-half wider, than long, the black 

 tubulation nearly two-fifths as wide as the base, the basal lobe very obtuse, 

 somewhat scabrous at tip; scutellum subquadrate, twice as wide as long, feebly 

 impressed medially; elytra only slightly longer than wide, evenly parabolic, 

 distinctly wider than the prothorax and fully two-thirds longer, the apex 

 somewhat obtusely rounded; grooves rather coarse, deep, sharply defined and 

 smooth, the second almost attaining the basal edge; metasternum with a 

 broadly impressed sulcus, sharp at the bottom, the first ventral abruptly flat,
