Brazilian Baring 477 



rufous; setules of the under surface small and sparse; beak short, thick, 

 shining, arcuate, finely, sparsely punctulate, two-thirds as long as the pro- 

 thorax, the antenna; medial; prothorax barely a fifth wider than long, the 

 sides distinctly and subevenly arcuate from base to apex, the latter scarcely 

 half as wide as the base; punctures fine and sparse, becoming moderately 

 coarse and rugulosely subconfluent at the sides, without trace of median 

 impunctate line; scutellum small, rather rounded; elytra a fourth longer 

 than wide, the sides but feebly oblique, slightly arcuate, the apex very 

 obtusely rounded, at the feebly tumid humeri slightly wider than the pro- 

 thorax three-fourths longer; grooves moderate, not evidently punctate, 

 becoming ' coarse and strongly punctate basally; intervals very finely, 

 sparsely, subserially punctate; pygidium densely cribrate, smaller and nar- 

 rower in the female; male without distinct abdominal characters. Length 

 VS-nmm.; width 1.45-1.5 mm. Brazil (Santarem). Two specimens. 



amazonica n. sp. 

 Form rather more narrowly oblong-oval, convex, polished, black, with subseneous 

 lustre and almost completely glabrous, the sparse squamules beneath very 

 feeble; beak thick, arcuate, shining, finely, not densely punctulate, scarcely 

 three-fourths as long as the prothorax, the antennae piceo-rufous; prothorax 

 much shorter, almost two-fifths wider than long, the sides just visibly con- 

 verging and feebly arcuate, more rapidly rounding anteriorly; apex some- 

 what more than half as wide as the base; punctures moderate, well separated, 

 a little less fine, shallow and sparsely subrugulose at the sides; median 

 impunctate line distinct and entire; scutellum moderate, ogival; elytra a 

 third longer than wide, circularly rounded behind, with very feebly oblique 

 sides, at the rather narrowly subprominent humeri evidently wider than the 

 prothorax, about twice as long; grooves rather narrow, smooth, gradually 

 a little coarser and moderately punctured basally, exarate at apex; intervals 

 with sparse infinitesimal punctulation; pygidium moderate, convex; under 

 surface black, the legs very pale and in strong contrast with the body color. 

 Length 2.75 mm.; width 1.25 mm. Brazil (Entre Rios). September. One

6— Body somewhat broadly and very evenly oval, convex, shining, piceous-black, 

 the legs and elytra more distinctly rufous, glabrous above, the slender 

 squamules of the under surface sparse; beak moderate, arcuate, very finely, 

 inconspicuously punctulate and two-thirds as long as the prothorax; antennae 

 piceo-rufous; prothorax a third wider than long, the sides strongly arcuate, 

 becoming straighter and subparallel basally and oblique distally; apex 

 scarcely half as wide as the base; punctures moderate, separated by fully 

 twice their diameters, rather smaller and feebler but close and subrugulose 

 laterally; median line narrowly impunctate for a short distance beyond the 

 middle; scutellum very small, rounded; elytra very evenly parabolic in 

 outline, scarcely a fourth longer than wide, at the scarcely tumid humeri 

 slightly wider than the prothorax, almost four-fifths longer; grooves fine, 

 smooth, very gradually becoming coarse and punctate basally; intervals 

 alutaceous posteriad, with series of very minute distant punctules; pygidium 

 tumid medially toward base. Length 2.2 mm.; width i.i mm. Brazil
