Brazilian Baring 313 



twice as long, the sides feebly, subevenly arcuate, rapidly rounding through 

 the obtuse apex, the humeri but feebly tumid; striae fine, the intervals with 

 minute and well separated unilineate punctulation; male abdomen finely, 

 remotely punctulate, with a deep and simple impression medio-basally, the 

 prosternum unarmed. Length i. 8-1.9 mm.; width 0.68-0.7 mm. Brazil 

 (Entre Rios). September. Two male specimens piceipes n. sp. 



Body broader than in the preceding, similar in lustre, coloration and in the 

 extremely fine, sparse and inconspicuous squamules, but with the legs 

 blackish-piceous; beak (0") not so slender, strongly and closely punctate 

 and longitudinally seriate, feebly tumid above basally, slightly bent dorsally 

 at the middle, the lower outline more nearly straight, three-fourths as long 

 as the prothorax, or ( 9 ) similar in length but much more slender and less 

 punctate; antennae slightly beyond the middle, more distinctly in the male; 

 prothorax nearly as long as wide, the sides as in the preceding; punctures 

 also nearly similar in form and distribution; elytra broader, not quite 

 one-half longer than wide, oval, with the humeri feebly tumid, slightly 

 wider than the prothorax and two-thirds longer; striae fine but deep; punc- 

 tures of the single interstitial series minute and widely spaced; male abdomen 

 convex, finely, sparsely punctate, with a distinct simple medio-basal im- 

 pression. Length 1.8-2.3 mm.; width 0.6-0.85 mm. Brazil (Santarem). 

 Seven specimens finitima n. sp. 



Body nearly similar but a little smaller, deep black and shining, the legs dark 

 rufous; fine squamules of the upper surface somewhat more numerous, less 

 minute and not so slender, being easily visible, though not conspicuous, in 

 the single interstitial series, also rather more evident beneath and similarly 

 not distinctly more numerous on the met-episterna; beak ( 9 ) very slender 

 and cylindric, somewhat punctate, rather distinctly arcuate, feebly tumid 

 above at base and slightly shorter than the prothorax, the latter similar in 

 form and sculpture, slightly shorter than wide in the female; elytra a little 

 narrower, similarly oval, with rather obtuse apex and feebly reentrant sutural 

 angle, one-half longer than wide, evidently wider than the prothorax and 

 three-fourths longer, the striae and sculpture nearly as in finitima; abdomen 

 rather finely, sparsely punctate, with evident fine squamules. Length 

 1.8-2.0 mm.; width 0.75-0.8 mm. Brazil (Chapada — forest). August to 

 November. Four specimens, all females intermedia n. sp. 



4 — Form narrow, parallel, black, with short and slender black legs; white 

 squamules above slender but rather close and distinct in single interstitial 

 series, beneath sparse but somewhat dense on the met-episterna and also on 

 the third and fourth abdominal segments; beak (d*) very short, cylindric, 

 feebly arcuate, closely sculptured, sparsely squamulose, not evidently tumid 

 above at base, four times as long as wide and not three-fourths as long as the 

 prothorax, or ( 9 ) much longer, very much more slender, smooth in great 

 part and about as long as the prothorax; antennae rufous, slightly ( 9 ) or 

 very greatly (o 71 ) ultra-median; prothorax as long as wide, the parallel 

 sides nearly straight, rounding and oblique in less than apical third; punc- 

 tures not very fine and separated by nearly twice their diameters; elytra 

 three-fifths longer than wide, parallel and straight at the sides, gradually 

 arcuate and subevenly rounded behind, barely visibly wider than the pro- 

 thorax and not quite twice as long; striae fine and rather evidently punctate, 

 the punctures of the single interstitial series infinitesimal; male abdomen 

 convex, minutely, sparsely punctate, having toward base a distinct narrow 

 impression along the median line. Length 1. 45-1. 7 mm.; width 0.45-0.6. 

 mm. Brazil (Chapada — forest). May and September. Six specimens.
