punctures coarse but separated, the spicules distinct, two in number and 

 subequal on the anterior. Length 5.2-5.3 mm.; width 3.1-3.3 mm. Brazil 

 (Chapada — forest) November. Three specimens decretus n. sp. 



Body fully as elongate, rhombic-oval, with shorter prothorax and longer elytra; 

 beak rather slender, feebly arcuate, not quite as long as the elytra, finely, 

 sparsely punctate, coarsely and unevenly on the compressed sides basally; 

 antennae brownish-rufous, distinctly behind the middle, slender, the first 

 two funicular joints very elongate and subequal, the second rather longer 

 than the next two; club moderate, abrupt and oval; prothorax fully one- 

 half wider than long, the strongly arcuate sides gradually parallel basally, 

 the plentifully punctate tubulation three-sevenths as wide as the base; 

 basal lobe punctulate, short, gradual, sinuato-truncate at apex; scutellum 

 flat, only one-half wider than long, subquadrate; elytra fully a fifth longer 

 than wide, almost twice as long as the prothorax and much wider, the oblique 

 sides arcuate, the apex somewhat broadly rounded; grooves deep, not 

 dilated at base, a little less deep and more punctate laterally; sterna medially 

 with plentiful golden squamules; abdomen impressed medially at base in 

 the male; femora very coarsely, closely punctate. Length 5.0-5.2 mm.; 

 width 3.2 mm. Brazil (Rio de Janeiro). December anthracinus n. sp. 



Body smaller and not quite so elongate, rhomboid-oval; beak slender, very feebly 

 arcuate, rather longer than the elytra in both sexes, finely, sparsely punctate, 

 more strongly but sparsely on the uncompressed sides basally; antennae 

 slightly behind the middle, slender, obscure red-brown, the basal funicular 

 not as long as the next two, the third a little less than twice as long as wide, 

 the seventh larger, pubescent and almost as wide as the club, which is nearly 

 as long as the preceding four joints; prothorax one-half wider than long, 

 the strongly arcuate sides becoming subparallel at base; tubulation large, 

 minutely, remotely punctulate, occupying apical fifth and nearly one-half as 

 wide as the base, the basal lobe slightly punctate and obtusely rounded; 

 scutellum short, transverse, smooth and broadly concave; elytra slightly 

 elongate, three-fourths longer than the prothorax, parabolic, with rather 

 strongly arcuate sides and narrowly rounded apex; humeri prominent both 

 laterally and dorsally; grooves very moderate but deep throughout, not at 

 all dilated basally; punctures of the entire under surface moderate and 

 sparse; femora with somewhat coarse, sparse punctures. Length 4.7-4.9 

 mm.; width 3.0 mm. Brazil (Chapada — forest). March and November. 

 Five specimens collucens n. sp. 



17 — Form more sharply rhombic, narrower, the thoracic tubulation relatively 

 larger, almost half as wide as the base. Polished and smooth; beak slender, 

 feebly arcuate, four-fifths as long as the elytra, minutely, sparsely punctate, 

 coarsely and unevenly so on the subcompressed sides basally; antennae long, 

 slender, medial, the first two funicular joints much elongated and equal, the 

 third about twice as long as wide; club fully as long as the three preceding 

 joints, rather abrupt; prothorax fully one-half wider than long, the strongly 

 arcuate sides becoming parallel basally, the tubulation distinctly punctate, 

 about a fifth the total length; basal lobe obtusely rounded but not very 

 gradually formed, punctate; scutellum transverse, flat and impunctate, 

 wider at apex than at base; elytra slightly elongate, twice as long as the 

 prothorax and nearly a third wider, the oblique sides only very feebly arcuate; 

 apex somewhat obtusely rounded, the humeri laterally, but not dorsally, 

 prominent; striae very fine and feeble, the punctures distinct; under surface 

 very finely, remotely punctate, the prosternal flanks more strongly and 

 closely; strong femoral punctures well separated. Length 6.0 mm.; width 

 3.7 mm. A single specimen, probably from Brazil, sent by Desbrochers des 

 Loges incultus n. sp.
