Brazilian Barin/e 173 



with very moderate, sparse and impressed punctures, becoming closer and 

 somewhat strong at the sides, wholly glabrous, the basal lobe moderate; 

 scutellum small, flat, oval, scarcely so wide as long; elytra parabolic, a 

 fourth longer than wide, slightly wider than the prothorax and very nearly 

 twice as long, the humeri but slightly prominent, rounded; striae not very 

 coarse but deep, abrupt and groove-like, smooth; intervals flat, three or 

 four times as wide as the grooves and with fine and feeble, uniseriate or, 

 on the wider intervals, biseriate punctulation; abdomen strongly convex. 

 Length 3.1 mm.; width 1.72 mm. Brazil (Santarem). One specimen — 

 apparently female 1 asphaltina n. sp. 



Basal lobe of the prothorax not evidently sinuate at apex 2 



2 — Pronotum very smooth, infinitesimally and sparsely punctulate, becoming 

 evidently punctate only at the extreme sides. Body more elongate-oval 

 than in the preceding, deep black and polished; hair-like brown squamules 

 of the elytra uniform, finer and sparser than in asphaltina; beak ( 9 ) as long 

 as the head and prothorax, more arcuate and thicker basally, rather thin 

 distally, strongly sculptured but shining; prothorax larger than usual, a 

 third wider than long, the sides moderately converging and very feebly 

 arcuate, gradually more rounding and convergent beyond the middle, to 

 the truncate apex, the tubulation feebly marked; basal lobe somewhat 

 rapidly formed, rounded, with the middle of the apex narrowly truncate; 

 scutellum small, flat, ogival, closely fitted; elytra more than a fourth longer 

 than wide, parabolic but rather obtuse at apex, evidently wider than the 

 prothorax and about twice as long; humeri somewhat prominent, rounded; 

 grooves deep, the punctures in single series, strong and conspicuous on the 

 narrower outer intervals, finer and more confused on the broad second and 

 third; abdomen strongly convex, with moderate loose punctuation. Length 

 3.1 mm.; width 1.65 mm. Brazil (Entre Rios). September. A single 

 specimen vitrina n. sp. 



Pronotum very finely and sparsely but more evidently punctulate and becoming 

 strongly punctate much more broadly toward the sides 3 



3 — Body smaller and narrower than in the preceding, elongate-oval, deep black 

 and polished, the fine dark squamules of the elytra even less evident; beak 

 as long as the head and prothorax, more gradually and feebly tapering and 

 more evenly arcuate than in vitrina, subsimilarly sculptured; prothorax 

 relatively smaller, two-fifths wider than long, with the converging sides from 

 base to apex much more evenly arcuate, the apex less evidently subtubulate 

 and relatively somewhat wider, being but little less than half as wide as the 

 base, the basal lobe somewhat shorter, more gradually formed and more 

 broadly truncate at apex; scutellum a little larger, oval; elytra a fourth 

 longer than wide, oval, only slightly wider than the prothorax and more than 

 twice as long, the humeri smaller and only very feebly prominent; grooves 

 and punctures almost similar, the first and second striae relatively finer, 

 shallower and indefinitely punctate; abdomen strongly, evenly convex and 

 loosely punctate. Length 2.65 mm.; width 1.4 mm. Brazil (Entre Rios). 

 September. One specimen intermedia n. sp. 



Body stouter than in any one of the three preceding, polished and deep black 

 throughout, more subrhombic-oval, convex, the fine dark squamiform hairs 

 of the elytra extremely sparse and indistinct, with a few, longer and paler 

 scattered along the base; beak strongly sculptured, as long as the head and 

 prothorax, rather thick basally, thinner and less arcuate distally; prothorax 

 almost one-half wider than long, the sides moderately converging and feebly 

 arcuate to about apical third, there rapidly rounding to the feeble constriction 

 and the truncate tubulation, which is slightly less than half as wide as the 

 base; fine punctures of the disk unusually remote but distinct; basal lobe
