458 Memoirs on the Coleoptera 



Pronotal punctures relatively rather coarse and very close, dense laterally, without 

 definite smooth median line. Body very small, narrowly oval, convex, 

 deep black and slightly shining; beak (o 71 ) moderately slender, equal, feebly, 

 evenly arcuate, strongly, closely punctate and three-fourths as long as the 

 prothorax; antennae moderate, with thick, oval and very abrupt club; 

 prothorax very nearly as long as wide, the sides feebly converging and very 

 slightly arcuate, gradually more rounding and oblique anteriad; apex more 

 than half as wide as the base, the basal lobe obtusely angulate; scutellum 

 well developed, free and transversely oval; elytra evenly and not obtusely 

 oval, over a fourth longer than wide, evidently wider than the prothorax 

 and three-fourths longer; grooves moderate, gradually finer from base to 

 apex; intervals with irregular series of fine but distinct, well separated 

 punctures; pygidium as usual in the genus, semicircular and strongly, evenly 

 convex; prosternal impression flat and gradually ascending posteriorly, 

 without trace of bifurcating prominence, but constricted medially as usual, 

 the lobe broadly truncate. Length 1.8 mm.; width 0.75 mm. Brazil 

 (Chapada — forest). November. One specimen restrictus n. sp. 



Pronotal punctures very moderate to small in size, always distinctly separated, 

 at least medio-basally, the color deep black throughout 19 



19 — Form very elongate-oval, the elytra almost one-half longer than wide; beak 

 not separated from the head by an impression. Deep black, convex and 

 shining; beak ( 9 ) slender, evenly and moderately arcuate, only feebly, 

 gradually thickened and strongly punctured basally and as long as the head 

 and prothorax; antenna; at two-fifths, the scape notably short; prothorax 

 but very little wider than long, the sides feebly converging and slightly 

 arcuate, rather rapidly oblique apically, the apex almost two-thirds as wide 

 as the base; punctures very moderate but deep, dense laterally, separated 

 by their own diameter medially, the smooth line not evident; scutellum 

 moderate, flat and rounded; elytra elongate-oval, very slightly wider than 

 the prothorax and three-fourths longer; grooves very moderate, only slightly 

 coarser distally, remotely punctate; intervals with single series of very small 

 but distinct, well separated punctures; pygidium moderate, strongly convex; 

 prosternal lobe medially sinuate at apex; coarse and close sternal punctures 

 each with a distinct slender squamule. Length 2.23 mm.; width 0.8 mm. 

 Brazil (Chapada — carripo). October. One specimen angustulus n. sp. 



Form more broadly oval as usual, convex, the elytra much shorter; beak sepa- 

 rated by an evident though shallow reentrant angle 20 



20 — Size moderate for the present genus 21 



Size minute 22 



21 — Form evenly oval, convex, strongly shining, the pronotum rather less so 

 than the elytra; beak (d 1 ) short, closely, strongly punctate, feebly arcuate 

 and three-fourths as long as the prothorax, or ( 9 ) a little longer, slightly 

 more arcuate and less thick, much more finely, sparsely punctate, even 

 throughout in both sexes; antennae submedial in both; prothorax (d*) 

 barely wider than long, more evidently (9), the sides feebly converging 

 and very slightly arcuate to the short and feeble apical obliquity; apex 

 much more than half as wide as the base; punctures moderate, dense and 

 coarser laterally, notably small and separated by nearly twice their diameters 

 medially, with an evident and almost even subentire median smooth line; 

 scutellum small, free and transversely oval; elytra a third to fourth longer 

 than wide, oval, slightly wider than the prothorax and only three-fifths 

 longer; grooves rather fine, deep, slightly coarser at apex, scarcely at all 

 punctate; intervals with single series of very small and widely separated 

 punctures; pygidium normal, convex. Length 2. 1-2. 15 mm.; width 0.8 

 mm. Brazil (Chapada). March. Two specimens umbratilis n. sp.
