Brazilian Baring 459 



Form more oblong-oval, rather stouter, convex and deep black, with less lustre 

 than in the preceding, the elytra rather shining; beak ( 9) longer than in 

 the preceding, equal to the head and prothorax, rather slender and evenly 

 arcuate, the antennae piceous, submedial, with very abrupt, stouter, paler 

 and still less pubescent club; prothorax fully a fifth wider than long, the 

 sides subinflated, parallel and arcuate, very gradually more converging; 

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

 laterally, rather small and separated by between once and twice their widths 

 medially, with a distinct impunctate line not attaining the apex; scutellum 

 very free, oval, rather less transverse; elytra nearly as in the preceding but 

 almost three-fourths longer than the prothorax, subsimilarly grooved and 

 punctulate; pygidium as usual, convex. Length 2.15 mm.; width 0.9 mm. 

 Brazil (Chapada). May. One specimen tritus n. sp. 



Form rather more broadly oval and somewhat larger, evenly oval, differing in 

 having the elytra duller than the pronotum as in alutaceus and some others 

 of that section; beak (cf ) four-fifths as long as the prothorax, feebly arcuate, 

 evenly rather thick and strongly punctured, or ( 9 ) but little less thick than 

 in the male, but almost as long as the head and prothorax and more arcuate, 

 somewhat less punctate; antennae very slightly behind and beyond the 

 middle in the female and male respectively, the scape about as long as the 

 entire stem; prothorax a fourth wider than long, the sides strongly arcuate, 

 becoming subparallel and straighter basally; apex half as wide as the base; 

 punctures rather coarse and very close laterally, less coarse but strong and 

 separated by about their diameters medially, without smooth line; scutellum 

 moderate, free, shining and slightly transverse; elytra evenly oval, a third 

 or fourth longer than wide, barely wider than the prothorax and nearly two- 

 thirds longer, sericeous in lustre; grooves very moderate, obscurely punctate; 

 intervals fully three times as wide as the grooves, the punctures of the single 

 series fine externally, but larger though shallow internally; pygidium very 

 small, less convex than usual; abdomen more strongly punctured than usual. 

 Length 2.2-2.3 mm.; width 0.85-0.95 mm. Brazil (Chapada— forest). 

 March and November. Four specimens imitator n. sp. 



22 — Body suboblong-oval, convex, the elytra slightly more shining than the 

 pronotum; beak (o 71 ) rather thick, evenly, feebly arcuate, strongly punctured 

 and four-fifths as long as the prothorax; antennae nearly black, medial, 

 rather short, the scape not as long as the stem, the club short, abrupt, thick 

 and oblong-oval; prothorax a fifth wider than long, the sides feebly con- 

 verging and very slightly arcuate, rather rapidly rounding and oblique in 

 apical third; punctures deep, only moderately coarse but dense laterally, 

 smaller and separated by nearly twice their diameters medially, without 

 impunctate line; scutellum moderate, somewhat transversely oval, not very 

 free; elytra parabolic, fully a fourth longer than wide, slightly wider than 

 the prothorax and three-fifths longer; grooves moderate, barely visibly 

 coarser at apex, not distinctly punctate; intervals with single series of 

 minute but evident and well separated punctures; pygidium normal, rather 

 strongly convex; abdomen finely and inconspicuously punctate. Length 

 1.7 mm.; width 0.7 mm. Brazil (Chapada — campo). October. One 

 specimen nanus n. sp. 



Body much more narrowly oval, convex, the pronotum finely, strongly, the 

 elytra more coarsely but strongly, micro-reticulate, the latter the more 

 shining; beak (d") equal in thickness, evenly and moderately arcuate, 

 strongly punctured and four-fifths as long as the prothorax; antennae sub- 

 medial, the scape almost as long as the stem, the club oval; prothorax a fifth 

 or sixth wider than long, the sides slightly converging, distinctly and sub-
