Brazilian Baring 303 



though sparse vestiture of narrow pale scales. The beak is moder- 

 ately long, cylindric, notably slender in the female, less so in the 

 male, feebly arcuate and in both sexes always strongly tumid 

 dorsally at base, just before the moderate sulcus separating it from 

 the head. The antennae are well beyond the middle(cf ), or medial 

 (9), the scrobes only feebly oblique, the scape long, not quite 

 attaining the base, the funicle slender, with the first joint long, 

 slightly longer than the next two, one or both of which is slightly 

 elongate, the club very moderate in size, abrupt, much narrowed 

 at base, oval and with its first segment fully half the mass, some- 

 times more. The prosternum (c?) has two slender oblique pro- 

 cesses, separated anteriorly by a deep cavity, or ( 9 ) is flat and only 

 with the usual transverse apical constriction; the coxae are very 

 moderately separated in both sexes. The legs are moderate, the 

 tarsi rather wide, the second joint more or less transverse, the third 

 dilated and bilobed and the claw-joint well developed. The pro- 

 thorax is tubulate at apex, though not very abruptly, and has the 

 base very broadly and gradually lobed medially, the scutellum 

 rather narrower than long and obtrapezoidal as a rule, strongly 

 impressed and glabrous, the elytra deeply and abruptly grooved. 

 The species appear to be somewhat numerous, those before me 

 from a single locality being as follows: 



Prothorax inflated and arcuate at the sides; sparse slender scales above conspic- 

 uous and pale fulvous in color, white beneath. Body oblong, convex, 

 shining, deep black throughout, the narrow fulvous scales above evenly 

 distributed, well separated, confused on the elytra, those beneath shorter, 

 broader and more decumbent, and also well separated throughout; beak (o 71 ) 

 evenly cylindric but not very slender, feebly arcuate, shining, strongly, 

 loosely punctate and sparsely squamulose, a little shorter than the prothorax, 

 the slender antennae, at three-fifths, blackish; prothorax not quite a third 

 wider than long, the parallel arcuate sides rapidly more rounding near the 

 apex, which is somewhat less than half as wide as the base; punctures 

 coarse, somewhat impressed and separated by their own diameters, the 

 scutellum small, free and subquadrate; elytra nearly one-half longer than 

 wide, the sides barely at all oblique, broadly, feebly arcuate, broadly and cir- 

 cularly rounded at apex, not wider than the prothorax and four-fifths longer, 

 the humeri slightly tumid; grooves with catenulate bottom, a third as wide 

 as the intervals, which are not finely, loosely, asperulately punctate; male 

 abdomen strongly, rather loosely punctate, deeply and simply impressed 

 medially toward base, the prosternal spines subporrect, feebly arcuate and 

 a third as long as the prothorax in the type. Length 5.0 mm.; width 2.15 

 mm. Brazil (Chapada). November. One specimen subinflatus n. sp. 



Prothorax not inflated, the subparallel sides evenly and feebly, though evidently, 

 arcuate, very much less so than in the preceding; scales throughout broader, 

 white, denser and very conspicuous. Form oblong, convex, deep black in 

 color throughout; scales above elongate and parallel, white, rather close-set 

 and conspicuous, beneath shorter, distinctly separated; beak (9) slender, 

 cylindric, smooth, shining and finely, sparsely punctate, abruptly strongly 

 and closely punctate and conspicuously squamulose at the thicker extreme
