striatopunctatus Csy. 



Elytral grooves never conspicuously punctate 10 



10 — Pronotum coarsely and loosely punctate 1 1 



Pronotum densely and more or less finely punctate; legs rufous 13 



11 — Prothorax shorter than wide, much less than half as long as the elytra; 

 body larger in size. Elongate-oval, deep black and rather shining, the legs 

 deep black and unusually short; pronotal squamules very fine, sparse, 

 darkish and inconspicuous, those of the elytra white, broader, distinct and 

 in single series, those beneath broader and somewhat close but not dense; 

 scutellum very densely albido-squamose; beak ( 9 ) not very slender, evenly 

 cylindric, shining, finely punctate, strongly arcuate and nearly as long as 

 the head and prothorax; antennae slender, medial and piceous; prothorax a 

 fourth wider than long, the sides straight and just visibly converging to 

 rather beyond the middle, thence gradually rounding and oblique to the 

 truncate apex, which is somewhat more than half as wide as the base; punc- 

 tures notably coarse and close, with narrow impunctate median line; elytra 

 oval, with arcuate sides and bluntly rounded apex, three-sevenths longer 

 than wide, distinctly wider than the prothorax; grooves deep and rather 

 coarse, finely punctate along the bottom; interstitial punctures in even 

 single series, somewhat coarse and close-set. Length 3.0 mm.; width 1.2 



mm. Brazil (Entre Rios). One example abruptus n. sp. 



Prothorax nearly as long as wide, about half as long as the elytra; body much 



smaller 12 



12 — Body narrowly oval, deep black throughout and rather shining, the legs 

 short; vestiture white, distinct, in even narrow single lines on the elytra, 

 very fine and sparse on the pronotum, but rather long, whitish and evident, 

 the scales beneath white and somewhat dense; beak (o 71 ) very thick, barely 

 longer than the prothorax, feebly arcuate, rather closely punctulate and 

 feebly constricted near basal third, not separated from the head dorsally; an- 

 tennae beyond the middle, short and somewhat stout, the piceous funicle, how- 

 ever, gradually very slender basally ; prothorax with the sides very feebly con- 

 verging and nearly straight, rounding a little anteriorly; punctures notably 

 coarse, slightly separated, the impunctate median line narrow and not very 

 obvious; scutellum densely albido-squamose; elytra three-sevenths longer 

 than wide, evidently wider than the prothorax and slightly less than twice 

 as long, the sides but slightly oblique and feebly arcuate; apex rather ob- 

 tusely rounded; grooves deep and abrupt; punctures of the even single 

 interstitial series somewhat coarse, well separated; male abdomen just 

 visibly impressed medio-basally, but not very differently squamose. Length 

 2.4 mm.; width 0.9 mm. Brazil (Santarem). One example. Named for 



Herbert H. Smith smithi n. sp. 



Body broader, black, with longer and bright rufous legs; vestiture somewhat 

 similar; beak (a 71 ) much thinner, even in thickness, feebly arcuate and much 

 longer than the prothorax, the antennae well beyond the middle; prothorax 

 with more oblique sides anteriorly, the punctures coarse but distinctly less 

 so than in smithi; elytra more broadly elliptic, with more prominent humeri; 

 abdomen only modified at base by having the squamules narrower and less 

 dense. Length 2.6 mm.; width 1.1 mm. Brazil (Para). [ N. parensis 



Csy. — Mem. Col., IX, p. 451] parensis Csy. 



Body narrowly oval, somewhat as in smithi, but with relatively larger and much 

 less punctate prothorax, black throughout, the legs dark rufous and longer; 

 vestiture nearly similar, except that the fine sparse pronotal squamules are
