Brazilian Barin/e 387 



behind the antennae, slightly thickened and strongly punctured, beyond the 

 antennae extremely thin — viewed in profile, moderately wide on the upper flat- 

 tened surface and ribbon-like; antennae in part piceo-rufous; prothorax fully a 

 fourth wider than long, the sides feebly converging and barely arcuate, gradually 

 rounding and then oblique and nearly straight beyond the middle, the apex 

 truncate and only two-fifths as wide as the base; punctures rather coarse, close 

 and deep, gradually becoming much smaller and sparse medially; elytra obtusely 

 oval, only a fifth longer than wide, with deep reentrant sutural angle, a fifth 

 wider than the prothorax and three-fifths longer, the umbones obsolete and the 

 humeri feebly swollen; grooves feebly punctate, half to third as wide as the even 

 flat intervals, which are strongly but loosely, confusedly punctate; under surface 

 strongly punctured, the abdomen finely and sparsely. Length 5.5 mm.; width 

 2.8 mm. Brazil (Chapada — campo). November. One specimen. 



The type is doubtless a female, and the male probably possesses 

 some striking sexual peculiarities. 



Tripusidia n. gen. 



The body in this genus is much smaller than in the preceding and 

 with very different beak; it is subrhombic-oval, convex, shining, 

 sparsely clothed with very slender squamules, fine and hair-like in 

 the single interstitial series. The beak is moderate in length and 

 somewhat slender, separated by a distinct sulcus and with the 

 mandibles bifid, arcuate and feebly decussate; antennae medial, 

 with subinferior scrobes and rather short scape, the first funicular 

 joint as long as the next two, the second twice as long as wide, the 

 others transverse but not very compact, increasing in width distally, 

 the club conic-oval, gradually ogivally pointed, well developed and 

 about as long as the five preceding joints, its basal segment short, 

 glabrous and shining as in the preceding genus. Prosternum flat, 

 with fine subapical constriction, squamose medially and on the large 

 sinuato-truncate posterior lobe, and with a distinct sinuate inter- 

 coxal suture, the coxae separated by rather less than their width. 

 Legs simple, short, the femora somewhat clavate, the tarsi short, 

 with the fourth joint thick and long, much longer than all the rest, 

 with the claws strong and divergent. Prothorax only very feebly 

 and obtusely constricted apically and imperfectly subtubulate, the 

 basal lobe as in the preceding genus, the scutellum flat and tri- 

 angular, but more obtuse at base than in Tripusus, the elytra and 

 female pygidium almost similar. The two species are as follows: 



Body moderately stout, rather convex, shining and deep black, with very faint 

 subaeneous lustre; beak ( 9 ) not very slender, evenly, feebly arcuate, cylin- 

 dric, coarsely, longitudinally sculptured at the sides and slightly longer than 

 the head and prothorax; antennae as described above; prothorax but 

 little wider than long, the sides moderately converging and evidently arcuate 

 — very slightly more so anteriad — -from base to the very feeble sinuses defining 

 the tubulation, the latter barely less than half as wide as the base; punctures
