Brazilian Barin/£ 71 



cate and externally dentate at base. Length 2.25 mm.; width 1.5 mm. 

 Brazil (Chapada — forest). November. One specimen sejunctus n. sp. 



13 — Beak unusually long and thin and nearly straight, a little longer than the 

 prothorax. Body less broadly rhomboid-oval, deep black and polished, 

 the abdomen feebly rufescent at apex; beak finely, not closely punctate 

 throughout, feebly swollen above at base — viewed in profile; antennal club 

 thick, as long as the six preceding joints; prothorax a sixth wider than long, 

 the sides moderately converging and feebly arcuate, slightly more anteriad, 

 the apex not evidently tubulate and almost half as wide as the base; surface 

 very smooth, sparsely punctulate near the sides, these punctures becoming 

 coarser and extending down the entire inferior flanks; basal lobe short, 

 broadly rounded, with a few submarginal punctures; scutellum moderate, 

 quadrate, somewhat concave; elytra evidently longer than wide, a fifth or 

 sixth wider than the prothorax, ogival, narrowly rounded at apex, the humeri 

 but feebly prominent; striae very fine but distinct throughout, smooth, not 

 evidently punctate, 1, 9 and 10 coarser; hind tibiae with the external sub- 

 basal tooth erect, aciculate at apex; first ventral evenly swollen and very 

 coarsely punctate. Length 2.8 mm.; width 1.75 mm. Brazil (Santarem). 

 One specimen of undetermined sex rostralis n. sp. 



Beak as usual, thick, feebly arcuate and much shorter than the prothorax 14 



14 — Body of unusually large size, oval; beak two-thirds as long as the prothorax, 

 not much compressed, strongly, not densely punctate, more finely above; 

 antennal club as long as the five preceding joints; prothorax rather strongly, 

 subevenly arcuate in profile, subsinuate anteriorly, a fourth wider than long, 

 the strongly converging sides strongly and evenly arcuate to the rather abrupt 

 tubulation, which is a third as wide as the base; surface very smooth through- 

 out; basal lobe broadly rounded, with very few punctures, the apex feebly 

 sinuate medially; lateral impressions at the basal edge very feeble and 

 diffuse; inferior flanks smooth, except at base and toward the coxae; tubu- 

 lation punctured at the sides; scutellum well developed, quadrate, smooth 

 and convex distally; elytra oval, barely longer than wide, a sixth wider than 

 the prothorax, the subapical prominences evident, so that the disk is sub- 

 truncate when viewed antero-obliquely; humeri broadly rounded; striae 

 strong, but becoming subobsolete though more definitely punctate on the 

 flanks, 1, 9 and 10 coarse and deep, but not punctured; hind tibiae sub- 

 truncate at base, the external angle obtusely rounded, though somewhat 

 prominent ; first ventral strongly swollen, very coarsely and densely punctate, 

 with the median line narrowly and feebly impressed. Length 4.8 mm.; 

 width 3.7 mm. Brazil (Constancia, Jan. 1857 — H. Clark). Communicated 

 by Desbrochers des Loges. One specimen globosus n. sp. 



Body more narrowly but very evenly oval, the humeri not at all prominent; beak 

 nearly similar, almost three-fourths as long as the prothorax, the transverse 

 reentrant angulation between upper surface and head more marked; antennal 

 club moderate; prothorax a fourth wider than long, the sides strongly con- 

 verging but only slightly arcuate, more rounded anteriad, the tubulation 

 more than a third as wide as the base; lateral edges with a few fine feeble 

 punctures, the inferior surface coarsely, remotely punctate near the coxae, 

 and more closely at base and on the tubulation; basal lobe rather narrow, its 

 apex sharply and deeply sinuate, smooth; scutellum slightly elongate, trun- 

 cate behind, the sides straight, converging from apex to base, which is 

 narrowly rounded, the surface smooth, deeply concave; elytra but slightly 

 elongate, between a fifth and sixth wider than the prothorax, sharply para- 

 bolic, the humeri not prominent; striae coarse suturally, very fine and punc- 

 tulate laterally, the ninth and tenth very coarse, conspicuously catenulate; 

 legs as in the preceding but somewhat shorter, strongly punctate; first ventral
