Brazilian Barin^e 335 



rule with narrow parallel scales, most of which are suberect and 

 bristling. The beak is moderate, evenly and distinctly arcuate, 

 strongly, longitudinally sculptured and basally squamulose (c?), or 

 barely longer but thinner and evenly tapering, smooth but basally 

 punctured and squamulose (9), not separated by an evident 

 impression and with the mandibles dentate within and arcuate 

 without, but not very decussate, so that they are prominent when 

 closed; antennae medial, rather short, the first funicular joint nearly 

 as long as the next four, 2-7 short, increasing slightly, shorter and 

 more compact in the male, the club well developed and oval, with 

 its first segment about a third of the mass. The prosternum sepa- 

 rates the coxas by their own width or slightly more, and has two 

 very slender oblique spines in the male, individually variable in 

 length as usual, or wanting. The legs are not abnormal, but the 

 tibiae and tarsi are relatively short, the prothorax not or but feebly 

 tubulate, the basal lobe small but distinct, rounded, the scutellum 

 subquadrate, moderately squamulose and free and the elytra 

 abruptly and deeply grooved, the grooves rather distinctly punctate. 

 The species are as follows: 



Upper surface with abundant suberect setiform squamules, yellowish in color.. .2 



Upper surface with very few short erect squamules, the pronotum more coarsely 

 and rugosely sculptured 3 



2 — Body oblong-oval, scarcely shining, piceous, the elytra and legs generally 

 more rufous, the sculpture coarse; beak about as long as the prothorax and 

 as described above; prothorax very little wider than long, the subparallel 

 sides feebly arcuate, more rapidly rounded anteriorly to the feebly constricted 

 apex, which is half as wide as the base; punctures strong, dense, more or 

 less longitudinally subconfluent, the median line smoother but very fine, 

 feebly subtumid; elytra more than a fourth longer than wide, oval, rather 

 strongly rounded at tip, only slightly wider than the prothorax and three- 

 fourths longer; grooves more than half as wide as the intervals, which are 

 confusedly punctato-rugose, the squamules in part confused; abdomen 

 convex, closely squamulose, all the squamules beneath decumbent; basal 

 segment not much modified in the male, the prosternal spines piceous, 

 rapidly porrect, varying from as long as the femoral thickness to three- 

 fourths as long as the prothorax. Length 2.3-2.8 mm.; width 0.85-1.25. 

 Brazil (Chapada — forest). May and September. Twelve specimens. 



hystrix n. sp. 



Body narrower and more parallel, smaller in size, slightly paler in coloration, but 

 similar in vestiture and sculpture; beak shorter, not quite as long as the 

 prothorax in either sex, thicker in the male; prothorax nearly similar, but 

 with the parallel sides straighter and somewhat more rapidly rounded 

 apically; elytra narrower, parallel basally, obtusely rounded behind the 

 middle, only very little wider than the prothorax and two-thirds longer; 

 sculpture almost similar, the grooves not quite so coarse; prosternum (o 71 ) 

 with the spines wanting to extremely short and conical; antennae shorter, 

 the first funicular joint very thick, scarcely as long as the next three. Length 

 2.15-2.3 mm.;, width 0.8-1.1 mm. Brazil (Chapada). On flowers, in forest 

 clearings. May. Four specimens soror n. sp.
