Brazilian Baring 449 



strongly and abruptly grooved. Pygidium very moderate, nearly 

 flat and semicircular. Legs rather short, all the tibiae sharply and 

 prominently angulate externally near base, the claws closely con- 

 tiguous. The two known species are as follows: 



Form oblong-oval, moderately convex, feebly shining, black throughout, the legs 

 piceous; beak (9) short, rather thick, cylindric, abruptly bent but not 

 tumid at base, separated by a moderately deep impression and four-fifths as 

 long as the prothorax, the antennae medial and black; prothorax fully two- 

 fifths wider than long, the sides subparallel and feebly arcuate, rapidly and 

 evenly rounded in about apical third, to the very short tubulation, which is 

 half as wide as the base; punctures coarse, deep and dense, gradually a little 

 less coarse and slightly separated medially, without trace of smooth median 

 line; elytra very obtusely oval, a fourth longer than wide, slightly wider 

 than the prothorax and twice as long, the humeral swellings scarcely at all 

 apparent; grooves laterally, basally and apically very coarse and punctate, 

 elsewhere less coarse; intervals as wide as the grooves laterally, but nearly 

 three times as wide as the latter suturally, coarsely, subtransversely and very 

 closely punctured in single line; under surface coarsely, closely punctate, 

 the abdomen finely and sparsely, but less finely though densely along base, 

 apex and sides. Length 3.5 mm.; width 1.75 mm. Brazil (Santarem). 

 One specimen tibialis n. sp. 



Form short, rather more narrowed anteriorly, oblong-ovoidal, convex, feebly 

 shining, deep black, the legs piceous-black; beak (9) very different, more 

 slender, rapidly inflated, compressed and densely punctate basally and as 

 long as the prothorax, the antennae near basal third; head extremely densely 

 punctate like the basal part of the beak; prothorax barely a fourth wider 

 than long, the sides converging and feebly arcuate, gradually a little more 

 so anteriorly, the more feeble tubulation less than half as wide as the base; 

 punctures coarse, very deep and extremely dense throughout, without trace 

 of median smooth line; elytra oblong, only a fifth longer than wide, the sides 

 parallel and feebly arcuate, broadly and subcircularly rounded in about 

 apical half, nearly a third wider than the prothorax and three-fourths longer; 

 grooves very coarse, deep and punctate laterally and basally, elsewhere less 

 coarse but still very conspicuous; intervals about as wide as the grooves 

 laterally, between two and three times as wide as the latter suturally, rather 

 coarsely, densely and confusedly punctate throughout; under surface some- 

 what coarsely, closely punctate, the abdomen closely, more finely but deeply 

 and conspicuously so throughout; legs densely, discretely punctate. Length 

 2.8 mm.; width 1.6 mm. Brazil (Santarem). One specimen. 



subpyriformis n. sp. 



These species can be identified at once by the coarse, dense 

 sculpture, coarsely grooved elytra, dentate tibiae and other features. 

 They somewhat resemble Baris and Eugivenius in habitus. 



Prantisus n. gen. 



This genus is one of the most remarkable of the present series in 



its very coarse sculpture and extremely short beak. The body is 



broadly, evenly oval and strongly convex, glabrous, excepting a 



minute slender squamule within each puncture, a little longer and
