but forming a large oblong and somewhat dense sutural area in basal half, 

 the third interval, at least in basal half, rather closely clothed with small 

 uniform fulvous-red squamules; beak (c?) dull, cylindric, not very slender 

 but strongly, evenly arcuate and fully two-thirds as long as the elytra, 

 strongly but not densely punctate basally and separated from the head by a 

 very shallow and broadly obtuse reentrant angle; antennae medial, moderate, 

 the scape extending much less than half way to the eye; prothorax a third 

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

 about the middle, thence broadly rounding and oblique to the apex; punc- 

 tures moderate, not very dense and rather shallowly impressed; median 

 smooth line distinct and entire; elytra more than a fourth longer than wide, 

 with rather narrowly rounded apex and very moderately arcuate oblique 

 sides, twice as long as the prothorax, the grooves moderate; intervals alter- 

 nating in width; male with the abdomen distinctly impressed and less 

 squamose medially toward base, the prosternal spines in the type slender, 

 straight, porrect and about as long as the prothorax. Length 3.2 mm.; 

 width 1.4 mm. Brazil (Entre Rios). September. One specimen. 



simiola n. sp. 



9 — Prothorax nearly as in the preceding group, not tubulate at apex 10 



Prothorax with an abrupt and well defined apical tubulation 11 



10 — -Form oval, feebly subrhombic, black throughout and alutaceous; pale 

 slender yellowish squamules forming three loose vittse on the pronotum, with 

 otherwise subglabrous surface, and, on the elytra, sparse but forming loosely 

 aggregated lines on the second interval toward apex and in basal half, and 

 on the fourth and sixth in very short posterior discal lines; on the under 

 surface broader, whitish and dense, sparser on the prothorax beneath, except 

 medially; beak (9) strongly arcuate, a little more so basally, just visibly 

 tapering, rather dull and somewhat shorter than the elytra, the antennae 

 moderate, piceous and well behind the middle; prothorax two-fifths wider 

 than long, the sides evenly convergent and evenly, moderately arcuate to the 

 truncate apex, which is rather more than half as wide as the base; punctures 

 coarse, very narrowly separated; scutellum small, subglabrous; elytra para- 

 bolic, only a fifth longer than wide, but little wider than the prothorax and 

 slightly less than twice as long; grooves moderately deep, the intervals 

 confusedly punctate, the fuscous scales dark brown. Length 2.5 mm.; 



width 1.2 mm. Brazil (Santarem). One example auguralis n. sp. 



Form narrower, the size somewhat smaller, slightly shining, similar in coloration, 

 the very slender yellowish squamules remotely scattered over the pronotum, 

 but rather more abundant sublaterally and along the middle, on the elytra 

 sparsely and confusedly mixed with the dark red-brown squamules, some- 

 what closer in a posterior discal spot, and on the second interval apically, 

 dense and whitish beneath, sparser on the mesosternum and side-pieces, and 

 especially less conspicuous on the prothorax beneath; beak (d") slender, 

 dull, evenly, somewhat strongly arcuate and fully three-fourths as long as 

 the elytra; antennae piceous, moderate and medial; prothorax a fourth 

 wider than long, conical, with straighter sides than in the preceding; punc- 

 tures coarse, deep and dense, slightly separated along the base; scutellum 

 small, quadrate and subglabrous; elytra a fourth longer than wide, parabolic, 

 very nearly twice as long as the prothorax and with rather coarse, deep 

 grooves; male with an extremely small erect spine before each anterior coxa. 

 Length 2.4 mm.; width 1.15 mm. Brazil (Para) — Baker. One example. 



devincta n. sp. 



Form rather stout, oval, piceo-rufous in color and not very shining, the pale 



slender yellowish squamules above scattered over the pronotum but closer 



at the sides and medio-basally, on the elytra sparse but closer on the first two
