elytra as in the latter throughout, though slightly shorter and rather more 

 obtuse behind, the two lateral striae a little coarssr, the legs nearly similar. 

 Length 2.15 mm.; width 1.35 mm. Brazil (Chapada). March. One female. 



perplexus n. sp. 



10 — Form narrowly subrhombic-oval, the prothorax very pale and bright rufous 

 above and beneath, the elytra and hind body slightly less pale testaceous, 

 the head, beak and legs piceous; beak only moderately thick and arcuate, 

 strongly sculptured and scarcely shorter than the prothorax; head evenly 

 convex, without trace of frontal fovea; prothorax as long as wide, the sides 

 moderately converging and nearly straight, rounding and more convergent 

 beyond the middle, the feebly tubulate apex three-sevenths as wide as the 

 base; surface very finely, sparsely punctate, the punctures gradually some- 

 what stronger but still sparse laterally, becoming coarse and close on the 

 inferior flanks; basal series coarser, the lobe small, sinuato-truncate; scu- 

 tellum small, quadrate, finely punctulate and nearly flat; elytra slightly 

 elongate, a sixth wider than the prothorax, ogival, with rather obtusely 

 rounded apex, the humeri but slightly prominent, broadly rounded; striae 

 rather coarse but shallow, distinctly punctulate, 7 and 8 subobsolete but 

 with distinct punctures, 9 and 10 moderately deep, catenulate; intervals 

 with some infinitesimal punctules in single series; hind tibiae with the external 

 angulation at base sharp but not prominent. Length 1.75 mm.; width 

 0.9 mm. Brazil (Chapada — forest). November. One specimen. 



defectus n. sp. 



11 — Body obtusely suboval, deep black throughout, the elytra very obscure rufo- 

 piceous. Beak moderately thick, arcuate and strongly not very densely 

 punctate, fully as long as the prothorax, the latter only a sixth wider than 

 long, the sides converging very moderately and evenly arcuate from base to 

 the feebly subtubulate apex, which is two-fifths as wide as the base; minutely, 

 remotely punctulate, with a narrow smooth median line, the punctures 

 gradually coarser and closer laterally, strong and close on the inferior flanks; 

 basal lobe moderate, sinuato-truncate, the lateral impressions small but 

 obvious; scutellum small, quadrate, nearly smooth and slightly concave, - 

 elytra but little longer than wide, oval, not sharply rounded at apex, a 

 sixth wider than the prothorax, the humeri broadly rounded and but slightly 

 prominent; grooves not very coarse but notably deep, abrupt and smooth, 

 7 and 8 finer, though very distinct, punctulate; external hind tibial angle 

 very acute and slightly prominent. Length 1.7 mm.; width 1.1 mm. Brazil 

 (Santarem). One specimen vapidus n. sp. 



Body bicolored, the prothorax rufous 12 



12— Form oval, with feebly marked and broadly rounded humeri, black, the 

 entire prothorax rufous; beak rather thick, feebly arcuate, strongly sculp- 

 tured and not quite as long as the prothorax, which is very nearly as long as 

 wide, the sides feebly converging and nearly straight, gradually rounding 

 and more converging beyond the middle, the subtubulate apex three-sevenths 

 as wide as the base, the lobe abrupt, very obtusely rounded and with stronger 

 punctures; surface finely and sparsely punctate, without smoother line, the 

 punctures gradually stronger but scarcely less remote laterally, becoming 

 coarse and very dense at the extreme sides and throughout the inferior flanks; 

 scutellum very small, quadrate, nearly smooth and concave; elytra slightly 

 elongate, ogival, with narrowly rounded apex and very moderately arcuate 

 sides, between a fifth and sixth wider than the prothorax, the grooves rather 

 coarse, deep, finely punctate along the bottom, 7 and 8 but slightly less 

 coarse; intervals even, somewhat concave, each with a series of minute and 

 widely spaced punctules; hind body beneath less coarsely punctate than 

 the propleura; outer hind tibial angle at base very acute and slightly prom-
