Brazilian Baring 125 



the anterior rather longer and thicker than usual; first abdominal segment 

 sparsely punctate, the first suture very sharply marked. Length 6.5 mm.; 

 width 4.3 mm. Brazil (Rio de Janeiro). October. One specimen — appa- 

 rently female severus n. sp. 



31 — Form rhombic-oval; beak rather thick and moderately arcuate, distinctly 

 longer than the head and prothorax, expecially in the male, coarsely, closely 

 sculptured, less so and more shining and apically a little more tapering in 

 the female; antennae inserted slightly behind the middle, rufous throughout, 

 the first funicular joint as long as the next two and thicker, the second 

 twice as long as wide, the club moderate, oval, concolorous; prothorax two- 

 fifths wider than long, the sides strongly converging, broadly and subevenly 

 arcuate from base to the moderate tubulation; basal lobe moderate, smooth, 

 with evident lateral impressions, the apex feebly sinuate medially; scutellum 

 moderate, subquadrate, minutely, sparsely punctulate and one-half wider 

 than long; elytra distinctly elongate, oval, three-fourths longer than the 

 prothorax and evidently wider, though not so greatly as usual, the humeri 

 unusually feeble in prominence; grooves deep and abrupt, rather strong, 

 the second attaining the basal edge, not dilated basally; presternum glabrous, 

 with deep and abrupt, moderately wide sulcus, without trace of spiniform 

 processes in the male; abdomen convex, minutely, remotely punctate, with 

 feebly marked first suture, the middle of the first segment feebly impressed, 

 but otherwise unmodified in the male; femora coarsely, deeply and closely 

 punctate, the spicules small. Length 3.8-4.2 mm.; width 2.6-2.8 mm. 

 Brazil (Rio de Janeiro). October and November. Three specimens. 



fatuus n. sp. 



Form nearly similar but larger and evidently stouter; beak (o 71 ) larger and 

 longer than in the male of fatuus, rather more arcuate, strongly, closely 

 sculptured and about half as long as the body; antennae similar, except that 

 the club is somewhat narrower and more gradually pointed; prothorax 

 similar in form, one-half wider than long, the moderately tubulate apex 

 scarcely three-sevenths as wide as the base, the basal lobe, scutellum and 

 elytra almost similar, the second rather larger, and the latero-medial convexity 

 of the elytral flanks is rather more distinct — almost obsolete in fatuus; under 

 surface and legs nearly as in fatuus, but the sparse punctures of the shallow 

 basal abdominal impression in the male are notably stronger and less minute. 

 Length 4.8-5.2 mm.; width 3.25-3.4 mm. Brazil (Rio de Janeiro). Novem- 

 ber. Two male specimens ineptus n. sp. 



32 — Body rather elongate, rhombic-oval; beak moderately arcuate and nearly 

 cylindric, strongly and somewhat closely sculptured, as long as the head and 

 prothorax ( 9 ), a little longer and heavier (o 71 ); antennae just visibly behind 

 the middle, rather slender, rufo-piceous, the second funicular joint much 

 elongated, longer than the first ( 9 ), or equal thereto (o 71 ), the club moderate, 

 gradually pointed; prothorax only between a third and fourth wider than 

 long, the converging sides distinctly arcuate, straighter basally but not 

 parallel; tubulation large, half as wide as the base, the latter with close 

 confused punctures throughout the width, the punctures bearing whitish 

 scales; basal lobe obtusely rounded, the lateral impressions nearly obsolete; 

 scutellum quadrate, punctulate, well developed and only a little wider than 

 long; elytra distinctly longer than wide, two-thirds longer than the pro- 

 thorax and distinctly wider, the humeri moderately prominent; outline 

 triangular, with broadly arcuate sides and moderately narrow rounded apex; 

 subapical prominences distinct; grooves strong and deep, the second not 

 quite attaining the basal edge and not at all dilated basally; presternum 

 with dense golden squamules, scarcely at all impressed along the middle, not 

 spinose in the male; abdomen convex, finely, sparsely punctate and feebly
