Brazilian Barin^e 121 



22 — Pronotum, as viewed in profile, moderately convex, more so basally; size 

 rather large 23 



Pronotum evenly and rather strongly convex behind the tubulation; elytra more 

 or less biundulated on the flanks 24 



Pronotum evenly and feebly convex; antennae more elongate, rufous 31 



23 — Form very stout, rhomboid-oval; beak rather thick, moderately arcuate, 

 subcylindric, strongly, somewhat closely punctured throughout and equal in 

 length to-the prothorax; antennae moderately short, blackish, with the basal 

 joint of the funicle much elongated, a little longer than the next two combined, 

 the second obconic, not quite twice as long as wide, the club rather narrow, 

 about twice as long as wide, as long as the preceding four joints; prothorax 

 fully two-thirds wider than long, the strongly arcuate sides becoming not 

 quite parallel basally; tubulation a fifth the total length, scarcely three- 

 sevenths as wide as the base, minutely, sparsely punctured; basal lobe 

 punctured and impresso-sinuate at apex, the lateral impressions moderate; 

 scutellum transverse, the hind margin feebly and evenly bisinuate; elytra 

 somewhat longer than wide, two-thirds longer than the prothorax and much 

 wider, the oblique sides feebly arcuate, the flanks biundulated; apex rather 

 strongly rounded, the prominent humeri broadly rounded; grooves somewhat 

 narrow but deep, smooth, 2 and 3 feebly dilated basally; abdomen feebly 

 impressed medio-basally, finely, sparsely punctate, more strongly toward the 

 sides of the impression; femora coarsely but not closely punctate, the 

 spicules distinct; prosternum glabrous, with very deep canal, which is 

 polished at the bottom. Length 6.4 mm.; width 4.6 mm. Brazil (Rio de 

 Janeiro). November. One example — probably male, but without proster- 

 nal spines retusus n. sp. 



Form, general characters and striation almost as in the preceding, but with the 

 body slightly more elongate; beak and antennae nearly similar, the latter 

 slightly longer, with the first funicular joint as long as the next two, the 

 second fully twice as long as wide, the club not quite so slender, more oval 

 and not quite twice as long as wide; prothorax less transverse, only three- 

 fifths wider than long, otherwise nearly similar throughout; scutellum 

 similar but with the hind margin broadly cuspido-angulate; elytra nearly 

 as in retusus, but very slightly longer and similarly with grooves two and 

 three not quite attaining the basal margin; under surface not differing 

 materially, the tibiae subangularly prominent externally toward base. Length 

 7.2 mm.; width 4.65 mm. Brazil (Rio de Janeiro). November. One 

 specimen conjunctus n. sp. 



24 — Prothorax most rounded near the middle, becoming truly parallel for some 

 distance before the base 25 



Prothorax subevenly and strongly arcuate at the sides, not becoming quite 

 parallel toward base, the sides straighter basally in campanulatus 26 



25 — Body stout, rhombic-oval, the lateral undulations of the elytra strong, the 

 median part rather prominently rounded; beak thick, moderately arcuate, as 

 long as the head and prothorax, somewhat finely but strongly, sparsely 

 punctate, irregularly at the sides basally; antennae medial, black, the first 

 funicular joint longer than the next two, the second obconic, one-half longer 

 than wide, the club narrow, cylindric, truncate at base, pointed in apical 

 third; prothorax three-fifths wider than long, the sides very oblique beyond 

 the middle; tubulation almost impunctate, more than a third as wide as the 

 base, the basal lobe nearly smooth, obtusely rounded, the lateral impressions 

 moderate; short transverse scutellum slightly convex, broadly and feebly 

 sinuate at apex; elytra barely longer than wide, much wider than the pro- 

 thorax and three-fourths longer; apex rather strongly rounded, humeri 

 evenly rounded; grooves abrupt, nearly smooth, 2 to 4 slightly dilated at
