Brazilian Barin^e 191 



arcuate, about two-thirds as long as the elytra, otherwise nearly similar, 

 except that the upper surface is slightly gibbous at base, the head not quite 

 so convex; antennae dark brown; prothorax fully two-fifths wider than long, 

 the sides somewhat more rounding anteriorly in the female than in the male; 

 punctures very dense but not quite so coarse, the smooth line obliterated 

 in about apical half; scutellum wider, deeply sinuato-truncate and with 

 closer, finer punctures, these wanting however at apex; elytra somewhat as 

 in the preceding but not quite so elongate and with the sides a little more 

 oblique and more arcuate, distinctly more than twice as long as the prothorax; 

 male with the punctures of the medio-basal and more finely squamulose 

 part of the abdomen much finer and less close-set than in gratus. Length 

 4-8-5.3 mm.; width 2.65-3.0 mm. Brazil (Chapada — forest). October and 

 November. Three specimens scitus n. sp. 



Body shorter and relatively stouter than in either of the preceding, somewhat 

 shining, deep black, the tibiae and tarsi scarcely paler; sculpture and vestiture 

 throughout almost as in the two preceding, the latter whitish-yellow, except 

 that on the upper part of the mes-epimera there are only a very few slender 

 squamules, and that the pronotal punctures, though strong and close, are 

 narrowly but appreciably separated; beak almost similar and strongly, 

 evenly arcuate, but longer, about as long as the elytra, more inflated basally 

 and with the thicker part more compressed and more evenly, closely punc- 

 tured, not so longitudinally rugose, its upper surface evenly arcuate to the 

 basal sulcus and not appreciably gibbous, the head similarly very convex; 

 antennae dark brown; prothorax short, fully one-half wider than long, the 

 smooth and nearly flat median line continuing to the apex, though narrowed 

 and less definite apically; scutellum obtrapezoidal, deeply sinuato-truncate, 

 smooth and impunctate; elytra much shorter, a fourth to less than third 

 longer than wide, relatively less obtuse and more strongly rounded at tip, 

 twice as long as the prothorax (cf), distinctly more ( 9 ); grooves and general 

 sculpture nearly similar; male with the broadly, feebly impressed basal parts 

 of the abdomen very finely, loosely punctate, each puncture with a glistening 

 slender yellowish squamule, the prosternal processes similarly extending 

 beyond the body by almost the length of the prothorax. Length 5.7-5.75; 

 width 3.1-3.2 mm. Brazil (Rio de Janeiro). October to December. Three 

 specimens cribricollis n. sp. 



6 — Form stout, oblong-suboval, deep black, the sculpture and vestiture nearly 

 as in cribricollis; beak rather strongly, evenly arcuate, as long as the elytra, 

 almost as in the preceding but less compressed at the sides, not gibbous 

 above, the head strongly convex; antennae pale brown; prothorax two-fifths 

 wider than long, the strong punctures very narrowly separated, gradually a 

 little coarser toward the median smooth line, which does not quite attain 

 the apex; basal lobe as usual, emarginate at apex; scutellum subquadrate, 

 smooth, feebly obtrapezoidal, sinuate and with acute angles at apex; elytra 

 parabolic, with rather narrowly rounded apex, a fourth longer than wide, 

 barely twice as long as the prothorax, the sculpture nearly as in the preceding; 

 abdomen (o 71 ) barely flattened, finely, densely punctate and minutely 

 squamulose medio-basally; ante-coxal spines extremely short, erect, only 

 three-fourths as long as the width of the anterior femora. Length 4.7 mm.; 

 width 2.5 mm. Brazil (Rio de Janeiro). October. One specimen. 



curtulus n. sp. 



7 — Form almost evenly suboval, deep black and feebly shining, the punctures 

 strong and dense almost throughout; ornamentation as in the preceding 

 species, except that there are one or two pale squamules at the base of the 

 sixth interval, and that beneath, the mes-epimera are nude, and that the 

 pale scales of the metasternum and sides of the first two ventrals are excep-
