Brazilian Barin/e 73 



piceous tinge; beak (9) exceptional, fully as long as the prothorax, thick 

 and arcuate basally, thence much thinner and more nearly straight to the 

 apex, finely punctate, shorter, more evenly thick and arcuate in the male; 

 antennae slightly behind the middle; prothorax very nearly as long as wide, 

 the sides converging and moderately, subevenly arcuate throughout; apex 

 not constricted, nearly two-fifths as wide as the base, the basal lobe moderate, 

 rounded, with an infinitesimal sinus; scutellum very small, narrower than 

 long, faintly impressed; elytra oval, a fifth longer than wide and a sixth wider 

 than the prothorax, the humeri very broadly rounded; discal stria? wholly 

 obsolete, not even traceable, the outer marginal evident but very shallow 

 and catenulate; femora simple; hind tibiae minutely denticulate externally 

 near the base. Length 1.8-2.0 mm.; width 1.15-1.35 mm. Brazil (San- 

 tarem). Two specimens solutus n. sp. 



Pronotum without trace of the basal series of punctures, except faintly on the 

 basal lobe; body shorter and more globose, piceous, the legs rufo-piceous, 

 the elytra dark rufous; beak moderately thick, feebly arcuate, finely, sparsely 

 punctate and rather shorter than the prothorax, the latter nearly a fourth 

 wider than long, the strongly converging sides subevenly arcuate from base 

 to the unconstricted apex, which is barely a third as wide as the base, the 

 basal lobe short, narrowly truncate at tip; scutellum very fiat and smooth, 

 quadrate, as wide as long; elytra but little longer than wide, a fifth or sixth 

 wider than the prothorax, the humeri rounded almost in continuation with 

 the sides of the elytra, not prominent; discal striae wholly obsolete and un- 

 traceable, the outer marginal alone visible, as in the preceding, and somewhat 

 similar; sides of the hind body with nearly similar very large though shallow 

 punctures beneath; tibiae almost similar. Length 1.65 mm.; width 1.15 mm. 

 Brazil (Santarem). One specimen vernicatus n. sp. 



4 — Outline almost regularly oval, the humeri barely visibly prominent and broadly 

 rounded, deep black; beak rather thick, subcylindric, feebly arcuate, not 

 quite as long as the prothorax, loosely punctate, more finely above; pro- 

 thorax just visibly wider than long, the converging sides feebly arcuate, more 

 rounding anteriad, the apex feebly subtubulate and two-fifths as wide as the 

 base; inferior flanks with punctures in the large anterior and posterior im- 

 pressions; basal lobe small, with a few punctules, the apex narrowly truncate; 

 scutellum very small, quadrate, slightly impressed medio-posteriad ; elytra 

 slightly elongate, a sixth wider than the prothorax, parabolic in form, with 

 strongly, evenly arcuate sides; discal striae extremely fine, nearly obsolete, 

 though easily traceable, more evident basally, 1, 9 and 10 deep and distinct, 

 the two outer catenulate; under surface rather coarsely but loosely punctate; 

 hind femora with a small inferior denticle and also a few very minute serrules; 

 tibiae slender, with a sharp prominent external tooth at some distance from 

 the base; first ventral not much swollen, densely but not quite so coarsely 

 punctate as usual. Length 2.2 mm.; width 1.3 mm. Brazil (Santarem). 

 One specimen conjux n. sp. 



Outline less evenly oval, more attenuate behind and smaller in size, similar in its 

 deep black color and in sculpture throughout, except that the discal elytral 

 striae are still more completely obsolete, the sutural stria finer, the two lateral 

 similar; beak nearly similar; prothorax almost similar but a little shorter, 

 the sides subevenly and more strongly arcuate; basal lobe narrowly truncate 

 at the middle of the apex; scutellum still smaller, quadrate, somewhat more 

 impressed longitudinally; elytra slightly elongate and a little wider than the 

 prothorax, much less oval and more triangular in form, the oblique sides 

 much less arcuate and the apex more narrowly rounded; femora with a 

 similar sharp inferior denticle just behind the middle, and also several very 

 minute serrules, the external tooth of the tibiae similar in position but very
