angles; elytra parabolic, a fourth longer than wide, evidently more than 

 twice as long as the prothorax; grooves deep, punctured along the bottom, 

 a fourth as wide as the flat, densely but not coarsely punctured intervals.

Ill — Form greatly elongated, rhombic-suboval, very moderately convex above, 

 strongly so beneath, black, feebly shining, deeply, though not very coarsely, 

 extremely densely punctured throughout above, more strongly and not quite 

 so densely so beneath, each puncture with a small squamule, dark brown 

 above, whitish beneath, the pronotum with an oblique lateral vitta, expanded 

 at base to the margin, the fourth strial interval not attaining the apex, and, 

 beneath, the entire met-episterna, all very densely clothed with bright red 

 scales; beak (o 71 ) evenly and strongly arcuate and as long as the elytra, 

 very evenly and feebly tapering throughout, strongly and densely punctate, 

 more finely apically, the upper surface with an even smooth line except 

 apically, separated from the head by a very feeble impression, or ( 9 ) very 

 much shorter, only very feebly arcuate, not very slender, more evenly cylin- 

 dric, slightly gibbous at base and scarcely more than three-fifths as long as 

 the elytra; antennae long, slender and piceous-black throughout in both 

 sexes; prothorax two-fifths wider than long, the converging sides evenly 

 arcuate to the moderately abrupt tubulation, two-fifths as wide as the base 

 (o 71 ), three-sevenths (9); entire median line very abruptly defined, smooth 

 and nearly flat; basal lobe strong, sinuate; scutellum subquadrate, nearly 

 smooth, glabrous, sinuate behind, with acute angles; elytra one-half (c?) 

 or three-sevenths ( 9 ) longer than wide, elongate-parabolic, with rather 

 prominent rounded humeri, nearly two and one-half times as long as the 

 prothorax, the grooves moderate, not distinctly punctate, a fourth or fifth 

 as wide as the intervals; male with large feeble medio-basal abdominal 

 impression, the ante-coxal spines porrect, abruptly deflexed at apex and 

 two-thirds as long as the elytra. Length 8.5-9.0 mm.; width 4.3 mm.

IV — Body subrhombic-oval, more convex than the preceding, black, rather 

 shining, the pronotum with a sublateral oblique vitta, not attaining the apex 

 and slightly expanded at base, of close-set elongate yellowish-red scales, also 

 some sparser narrower whiter squamules along the median line, obsolete 

 apically, the fourth strial interval with dense reddish-yellow scales in four- 

 fifths, the scutellum and entire suture narrowly clothed with sparser and 

 whiter squamules, the met-episterna and sides of the first two ventrals, 

 abruptly, also densely clothed with the reddish-yellow scales; punctures 

 throughout coarse and close, each with a small squamule — brown above, 

 whitish beneath and toward the sides of the elytra; beak feebly arcuate, 

 finely, loosely punctured throughout, three-fourths as long as the elytra and 

 rather rapidly thicker basally ( 9 ), or a little shorter and more uniformly 

 thicker (o 71 ), gibbous at the basal sulcus in both sexes, the head strongly 

 convex; antennae blackish-piceous, inserted evidently behind the middle; 

 prothorax two-fifths wider than long* the converging sides evenly and rather 

 strongly arcuate from base to the short and feebly marked or subobsolete 

 tubulation, the smooth median line obsolete; scutellum quadrate, closely 

 squamulose, with acute hind angles; elytra a third longer than wide, para- 

 bolic, with somewhat prominent, rapidly rounded humeri, between two and 

 three times as long as the prothorax; grooves rather narrow, the intervals 

 very coarsely, confusedly punctate; male without marked abdominal charac- 

 ters and wholly without prosternal spines. Length 4.5-4.6 mm.; width 2.3- 

 2.4 mm. Brazil (Chapada). March and November. Three specimens.
