Brazilian Baring 115 



base; antennae inserted near basal third, slender, blackish piceous, the third 

 joint twice as long as wide; prothorax not quite one-half wider than long, 

 the sides strongly arcuate, gradually subparallel posteriorly, the apex broad, 

 almost half as wide as the base, the constriction with fine and sparse punc- 

 tures, the basal lobe with a few small and sparse punctures, gradual, broadly 

 subtruncate; scutellum transverse, with transverse discal canaliculation; 

 elytra triangular, with feebly arcuate sides and narrowly rounded apex, a 

 little longer than wide, three-fourths longer than the prothorax; grooves 

 sharply defined and deep, almost impunctate, not at all dilated at base; 

 inferior flanks of the prothorax almost impunctate, except at apex and base; 

 punctures sparse throughout; anterior femora with two small and slender 

 spicules. Length 5.5 mm.; width 3.6 mm. Brazil (Santarem). One 

 specimen coruscans n. sp. 



Form less sharply rhombic; beak even longer and more arcuate, especially 

 toward base, fully as long as the elytra, the sparse punctures not so coarse 

 basally; antennae slender, dark rufous, the third joint fully twice as long as 

 wide; prothorax a little more than one-half wider than long, the sides more 

 rapidly converging and more feebly arcuate from base to constriction, 

 becoming parallel only near the base; apex narrower, barely two-fifths as 

 wide as the base; punctures nearly similar, the basal lobe less obtuse and 

 with the punctures stronger; scutellum transverse, broadly, evenly and 

 feebly concave; elytra triangular, with strongly arcuate sides and very 

 narrowly rounded apex, not longer than wide, two-thirds longer than the 

 prothorax, the grooves similar; inferior thoracic flanks deeply and evenly 

 punctured throughout; anterior femora with the inner spicule slender but 

 distinct, the outer very minute; femora finely sparsely punctate. Length 

 5.7 mm.; width 3.75 mm. Brazil (Santarem). One specimen. 



fulvicornis n. sp. 



11 — Sides of the prothorax becoming abruptly parallel and nearly straight in 

 basal third; form rhomboidal; beak slender, moderately arcuate, fully as 

 long as the elytra, finely, toward base rather coarsely and more closely, 

 punctate; antennae scarcely behind the middle, slender, dark rufous, the 

 third joint more than twice as long as wide; prothorax fully one-half wider 

 than long, the sides subangulate, though rounded, near basal third, thence 

 strongly converging and very feebly arcuate to the minutely, sparsely 

 punctured constriction; apex three-sevenths as wide as the base, the ba- 

 sal lobe rather rapidly formed, feebly punctulate and somewhat strongly 

 rounded; scutellum very short, broadly, feebly concave; elytra slightly longer 

 than wide, triangular, with feebly arcuate sides and moderately narrow 

 rounded apex, two-thirds longer than the prothorax, the inner deep grooves 

 not dilated at base; inferior thoracic flanks rather finely, sparsely punctured 

 throughout; femora with strong but well separated punctures, the anterior 

 with two small and very slender, equal spicules. Length 5.0 mm.; width 

 3.3 mm. Brazil (Rio de Janeiro). One specimen subangulatus n. sp. 



Sides of the prothorax as in the preceding, except that the posterior subangulation 

 is more broadly rounded and a little more distant from the base, the sides 

 before them less strongly converging and more arcuate to the tubulation, 

 which is very slightly longer and broader, similarly punctulate; beak nearly 

 similar, but with the upper surface broadly tumid basally, and not perfectly 

 even in curvature as in the preceding; prothorax scarcely one-half wider 

 than long, the basal lobe more obtusely rounded at apex; scutellum trans- 

 verse but not so short, flatter; elytra almost similar but with rather more 

 arcuate sides and more broadly rounded apex; under surface nearly similar, 

 . except that the met-episterna are a little broader; legs notably shorter, the 

 femora still more coarsely and very densely punctured. Length 5.25 mm.;
