Brazilian Baring 55 



subparallel posteriorly, the surface with the sparse infinitesimal punctules 

 becoming gradually stronger medio-basally, the lobe and lateral impressions 

 almost similar; scutellum transversely quadrate, feebly convex, perfectly 

 smooth and polished; elytra nearly similar in form and striation, but more 

 narrowly rounded at apex; abdomen somewhat more closely punctured 

 throughout, the basal segment almost similar. Length 5.8 mm.; width 3.9 



mm. Brazil (Chapada). November. One example integra n. sp. 



Body subsimilar but narrower than in either of the preceding, the elytra deep 

 black, polished, with a very feeble small oblique rufescent streak at each side 

 of the scutellum'; pronotum bright red, feebly alutaceous, the tubulation 

 and head as in rufopicea, much narrower than in integra: beak in the female 

 as in the former; prothorax somewhat smaller, a little more than a fourth 

 wider than long, the sides nearly as in the preceding, more regularly converg- 

 ing and arcuate than in rufopicea, though notably more converging anteriorly 

 than from base to about the middle; basal lobe in punctuation and fine 

 apical setae, as well as feeble lateral impressions, nearly as in the latter; 

 scutellum similar; elytra nearly similar in striation but longer, a little longer 

 than wide and more narrowly rounded at tip; abdomen almost similar. 

 Length 5.6 mm.; width 3.7 mm. Brazil (Chapada). November. One 

 specimen striatella n. sp. 



These forms are from the same region and bear a striking inter- 

 resemblance, but appear to be different taxonomically. The second 

 specimen of plenicollis has the scutellum a little smaller than in the 

 type and feebly, lunately impressed along the hind margin, in a 

 way not suggested in the type, but all the other features are so 

 similar that this may prove to be a simple abnormality. 



Crepantis n. gen. 



The very small species forming the type of this genus differs 

 greatly in general habitus from any other considered thus far, 

 though resembling somewhat a few of the small forms of Hiotus; 

 the tarsal claws, however, are not free as in the latter genus but are 

 straight and connate at base, as in all the preceding genera. The 

 body is narrower and much more evenly oval in outline, and the 

 short stout beak is separated from the head by a deep transverse 

 sulcus. The second species here added agrees in all features, except 

 the distally tapering beak, wholly polished prothorax and unarmed 

 tibiae. The two species, of which the first is the type, may be 

 described as follows: 



Body evenly oval, glabrous, not quite so strongly convex as in Diorymerus, pale 

 testaceous in color throughout, the legs but little darker, the head and beak 

 black, the pronotal tubulation short, not darker in color; beak thick, feebly 

 arcuate, as long as the prothorax, compressed, subopaque and strongly punc- 

 tured at the sides, finely and more sparsely above; antennal club large, thick, 

 oval and as long as the funicle; prothorax short, two-fifths wider than long, 

 the sides converging and subevenly arcuate from base to tubulation; surface 

 with deep and sparse punctures, less coarse medially than at the sides, the 

 apex smoother; basal lobe small and feeble, narrowly rounded at tip; scutel-
