thick basally, strongly, closely sculptured throughout and as long as the 

 elytra, the antennae medial, deep black, the first funicular joint shorter 

 than the next two, the second obconic, one-half longer than wide, the club 

 fusiform, as long as the preceding five joints, or ( 9 ) much shorter, scarcely 

 so arcuate distally, less strongly sculptured, scarcely more than two-thirds 

 as long as the elytra; prothorax rufous, black only medially beneath, a 

 fourth (cf ) to two-fifths ( 9 ) wider than long, the sides subparallel, broadly 

 arcuate, gradually a little more so anteriorly, the tubulation abrupt, a sixth 

 the total length, two-fifths (o 71 ) or three-sevenths ( 9 ) as wide as the base; 

 basal lobe obtusely rounded, strongly, closely punctate; scutellum transverse, 

 broadly sinuate behind, glabrous and smooth, very short and concave (o* ), 

 or less transverse and flat (9); elytra triangular, with broadly arcuate 

 sides and strongly rounded apex, much wider than the prothorax, but only 

 one-half longer; grooves rather coarse, deep and abrupt, the second and 

 third very gradually broader basally; presternum with the sulcus very 

 shallow, having (cf) two rather strong slender processes and a very deep 

 oval perforation, the abdomen feebly impressed and rather finely, remotely 

 punctate at base, the prothorax at each side anteriorly with a transverse 

 excavation bordered behind by a series of erect spines, or ( 9 ) without 

 prosternal processes or perforation and wholly devoid of the anterior thoracic 

 excavations, the abdomen finely, sparsely punctate, the first segment with 

 a feeble longitudinal impression. Length 6.5-7.2 mm.; width 3.9-4.4 mm. 

 Brazil (Chapada — campo). October. Eight specimens. . .coronatus n. sp. 

 Form stouter, larger in size, rhombic-oval, the prothorax more obscure rufous; 

 beak ( 9 ) short, thick, cylindric, feebly arcuate, strongly sculptured, with 

 minute and sparse squamules, and only as long as the head and prothorax; 

 antennae medial, piceous, the first funicular joint not quite as long as the 

 next two, the second almost twice as long as wide, obconic, the club very 

 moderate, not as long as the preceding four joints; prothorax one-half 

 wider than long, evenly campanulate, the sides evenly and strongly rounded, 

 becoming not quite parallel at base, the tubulation two-fifths as wide as the 

 base, with very few punctures; basal lobe very obtuse, slightly impresso- 

 sinuate at apex, with fine punctulation and some small slender squamiform 

 hairs; scutellum smooth, one-half wider than long, slightly convex, with a 

 small basal impression; elytra slightly longer than wide, much wider than 

 the prothorax and three-fourths longer, evenly and rather obtusely parabolic, 

 the prominent humeri evenly rounded; striae moderate, shallow but distinct 

 and punctate, the first two grooved, the first three strongly dilated and deep 

 at base, the outer two very coarsely and deeply impressed; prosternal sulcus 

 deep; abdomen rather closely and strongly punctate, the first segment 

 impressed along the middle; femora somewhat finely, sparsely punctate. 

 Length 7.5 mm.; width 5.0 mm. Brazil (Chapada — campo). November.

 arcuate, strongly, closely sculptured and as long as the head and prothorax; 

 antennae medial, black, short, the first funicular joint nearly as long as the 

 next three, the second but little longer than wide, the outer joints shorter, 

 the club as long as the preceding five; prothorax nearly three-fifths wider
