Brazilian Baring 259 



arcuate, rapidly rounding at apex to the tubulation, which is half as wide 

 as the base (o 71 ), a little wider (9); basal margin with narrow eroded line 

 of punctures, the lobe small, feebly sinuate at tip; scutellum small, quadrate, 

 feebly impressed and free; elytra elongate, triangular, more than a third 

 longer than wide, with broadly arcuate sides, rather strongly rounded apex 

 and elevated humeri, somewhat more than twice as long as the prothorax, 

 with moderate and very abrupt grooves; male with the abdominal base 

 flattened, finely, sparsely punctate and more or less rufescent, the prosternal 

 spines very short, erect, the intermediate surface very moderately excavated 

 and somewhat squamose. Length 3.6-3.75 mm.; width 1. 65-1. 75 mm. 

 Brazil (Chapada — -forest). October. Three specimens. . tenuinotatus n. sp. 



Dense short basal line of the third interval cuneiform 11 



11 — The dense line pure white. Body larger, deep black and polished; densely 

 squamose areas of the under surface nearly as in the preceding, but without 

 scattered finer squamules; beak ( 9 ) very slender, cylindric, smooth, evenly 

 and strongly arcuate and as long as the elytra, very abruptly thick, cylindric 

 and strongly, sparsely punctured in basal fifth; antennae subbasal, with very 

 short scape and long funicle, the joints thick but all longer than wide, the 

 club relatively small, only as long as the three preceding joints, oval, with 

 fine and feeble sutures and very long basal segment; prothorax a third 

 wider than long, the sides evenly arcuate, becoming subparallel at base, the 

 tubulation four-sevenths as wide as the base; line of fine dense punctures 

 along the base confused, the lobe very short, with a small and feeble sinus 

 at the middle; scutellum nearly as in the preceding; elytra almost as in the 

 preceding, but with less sharply elevated humeri and more notably exceeding 

 the prothorax in width, much more than twice as long as the latter, the 

 dense line of the third interval a fifth the total length. Length 4.3 mm.; 

 width 2.1 mm. Brazil (Chapada). March. One example. 



antennatus n. sp. 



The dense line of the third interval pale yellow; body smaller and more oval, 

 the elytra shorter, much less than twice as long as the prothorax — at least 

 in the male 12 



12 — Body (cf) narrowly rhombic-oval, smooth, polished and deep black; head 

 extremely convex; beak very long, cylindric, strongly and evenly arcuate, 

 finely, sparsely punctate, gradually tapering distally and nearly three- 

 fourths as long as the body; antennae at apical fourth, the first two funicular 

 joints rather elongate, the outer joints not transverse, the club elongate, 

 claviform and about as long as the five preceding joints; prothorax only a 

 fifth wider' than long, the sides evenly arcuate, becoming parallel at base, 

 the tubulation fully half as wide as the base, where the marginal impressed 

 line is fine and only feebly punctulate; scutellum small, flat, quadrate, very 

 little wider than long; elytra barely over a fourth longer than wide, narrowly 

 parabolic, with elevated humeri, three-fourths longer than the prothorax and 

 a fourth wider, the grooves moderate, the squamose line extending through 

 barely more than basal fourth; male abdomen feebly, irregularly impressed 

 and with moderate but close-set punctures medio-basally, and with a few 

 squamules behind each coxa, the prosternal spines arcuate and half as long 

 as the prothorax in the type, the cavity between them deep, circular and 

 moderate in size; anterior tibiae not distinctly fimbriate within. Length 

 3.75 mm.; width 1.7 mm. Brazil (Chapada — campo). November. One 

 male example debilis n. sp. 



Body (d 71 ) somewhat more rhombic, deep black, smooth and polished; beak 

 much shorter, cylindric, evenly and rather strongly arcuate, sparsely but 

 very distinctly punctate, gradually tapering distally and but little longer 

 than the elytra; antennae slightly behind two-thirds, shorter, but with
