Brazilian Baring 249 



fifth segment just visibly less squamose medially; beak (cf) as long as the 

 head and prothorax, moderately and evenly arcuate, cylindric, not very 

 slender, finely, sparsely punctate and shining, squamose at the sides basally, 

 or similar though a little longer (9); antennae just visibly beycmd (o 71 ) or 

 behind ( 9 ) the middle, piceous, moderate, the first funicular joint notably 

 elongate, nearly as long as the next three; prothorax fully two-fifths wider 

 than long, the sides converging and subevenly, rather strongly arcuate to 

 the truncate apex; elytra a fourth longer than wide to slightly more, para- 

 bolic, but with narrowly rounded apex, only very little wider than the pro- 

 thorax and less than twice as long; grooves deep, producing rather wide 

 partings of the vestiture; prosternum with the anterior transverse constric- 

 tion obsolete. Length 3.4-3.85 mm.; width 1.7-2.2 mm. Brazil (Chapada). 

 November. Six specimens merita n. sp. 



Scutellum much smaller; elytra without denuded sutural line posteriorly 3 



3 — Form suboblong-oval, convex, black, densely clothed with broad parallel 

 white scales, forming a still more compact crust beneath, less elongate than 

 in the preceding; beak similar but longer, a little longer than the head and 

 prothorax in both sexes; antennae rufescent, submedial; prothorax shorter, 

 two-fifths to one-half wider than long, the converging sides from base to 

 apex evenly and rather strongly arcuate; apex truncate and much less than 

 half as wide as the base; scutellum with small, sparse squamules; elytra 

 oval, a fourth longer than wide, more obtuse at apex than in the preceding 

 and distinctly more than twice as long as the prothorax; grooves somewhat 

 coarse and deep; male sexual characters of the abdomen nearly similar. 

 Length 3.25-3.35 mm.; width i. 65-1. 7 mm. Brazil (Chapada). November. 

 Two specimens condensata n. sp. 



Form narrower than in merita, the dense scales of the upper surface ochreous in 

 color, somewhat whiter on the pronotum in a feeble sublateral vittiform 

 area toward base, whiter and forming a dense crust beneath; integuments 

 black, the legs rufescent as in the preceding; beak (9) longer and more 

 slender, fully two-thirds as long as the elytra, similarly punctulate, shining 

 and basally squamulose, but not evenly arcuate, being straighter beyond 

 the antennae, which are rather long and slender and slightly behind the middle; 

 prothorax a third wider than long, the sides evenly and somewhat strongly 

 arcuate, becoming subparallel at base, the truncate apex much less than half 

 as wide as the base; scutellum small, only loosely squamulose; elytra a 

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

 very slightly wider than the prothorax and barely twice as long, the grooves 

 deep and rather coarse, especially toward apex, where the intervals gradually 

 have two, or rarely one, series of squamules; prosternum nearly flat, the 

 squamules similarly radiating outwardly from a central point, but here 

 shorter than in the two preceding; transverse constriction wanting as in 

 both of the preceding. Length 3.4 mm.; width 1.7 mm. Brazil (Chapada). 

 November. One specimen inopina n. sp. 



4 — Mandibles small and slender, very acute, everted in apical half. Body 

 oblong, subparallel, black, with rufous legs and beak; scales above pale 

 yellowish-brown, very close-set and uniform, dense and white on the thoracic 

 lobe and scutellum, whiter and dense beneath; beak (9) short, cylindric, 

 slender, smooth, very moderately arcuate and barely longer than the pro- 

 thorax, scarcely thicker but squamulose at base; antennae medial, rufous, 

 moderate and of the usual structure; prothorax short, nearly two-fifths 

 wider than long, the sides parallel and straight in basal half, then rounding 

 and oblique to the truncate apex, which is half as wide as the base; punctures 

 and squamules dense and very uniform throughout; scutellum subquadrate, 

 distinct; elytra more than a fourth longer than wide, somewhat parallel,
