Brazilian Baring 283 



5 — Form oval; color black throughout, scarcely shining; squamules whitish 

 above, very dense and pale yellow throughout beneath; denuded area at 

 the sides of the prothorax very large, so that the lateral pronotal vitta becomes 

 very narrow, distant from the margin and subobliterated beyond the middle; 

 entire apex with loose long squamules, almost wanting along the median 

 line, but close and distinct basally; interstitial series of the elytra denuded — 

 that is, as usual, replaced by dark squamules — basally throughout the width, 

 except just behind the humeri, and also along the sides and at apex, the 

 white squamules of the first interval attaining the apex; beak (cf) thick, 

 shining, moderately compressed and sculptured and a little longer than the 

 prothorax; antennae obscure rufous, at four-sevenths; prothorax only a fifth 

 wider than long, the broadly arcuate sides becoming subparallel basally, the 

 truncate apex four-sevenths as wide as the base; punctures strong, close, a 

 little less so beyond the middle; scutellum oblong, very densely squamose; 

 elytra evenly elliptic, a third longer than wide, barely twice as long as the pro- 

 thorax, the humeri evidently prominent laterally; grooves deep, somewhat 

 punctured along the bottom; rather strong and close uniserial punctures of the 

 intervals somewhat confused on the three inner; male abdomen with the 

 dense crust of scales a little thinner and feebly impressed medio-basally. 

 Length 3.0 mm.; width 1.35 mm. Brazil (Santarem). One specimen. 



interruptus n. sp. 



Form, coloration, sculpture and vestiture nearly similar, but with the space at 

 the sides of the prothorax not denuded but sparsely and finely squamulose, 

 so that the lateral pronotal vitta is evident throughout but composed of fine, 

 sparse squamules, denser at base; interstitial series of the elytra differing 

 in being entire throughout; beak (cf) nearly similar but not quite so thick, 

 and with the antennae more distal, at three-fifths, or (9) scarcely thinner and 

 but slightly less sculptured, but as long as the head and prothorax, with the 

 antennae at four-sevenths, blackish, with dull rufous funicle; prothorax 

 barely visibly shorter than wide, the sides subparallel basally, a little more 

 arcuate anteriorly, the apex half as wide as the base (cf), or more (9); 

 punctures strong, deep and very close-set throughout, even; scutellum well 

 developed, rounded-subquadrate, very densely squamose; elytra evenly but 

 rather obtusely elliptic, nearly a third longer than wide, slightly more than 

 or about a half longer than the prothorax; interstitial series confused toward 

 the suture, except behind the middle; male abdomen with the very dense 

 squamose crust only just visibly subimpressed and thinner medio-basally. 

 Length 2.8-3.2 mm.; width 1. 3-1 .4 mm. Brazil (Chapada — forest). March 

 and November. Seven specimens lateralis n. sp. 



6— Body narrowly subrhombic, deep black, the legs picescent; surface almost 

 opaque; vestiture white, the larger scales beneath narrowly separated; beak 

 (cf) even in thickness, strongly, closely punctate and a little longer than 

 the head and prothorax, or ( 9 ) distinctly longer, somewhat more arcuate, 

 smoother and slightly tapering distally, in both separated from the head by 

 a rather distinct reentrant angle; antennae rufous, medial (9), at four- 

 sevenths (cf); prothorax not quite as long as wide, the feebly converging 

 sides just visibly arcuate, more rounding apically; punctures strong, dense, 

 a little less so anteriorly; median vitta of loose slender squamules as wide as 

 the lateral; scutellum small, quadrate, squamose; elytra nearly a third 

 longer than wide, the oblique sides broadly, distinctly arcuate, the apex 

 rather narrowly obtuse, nearly a fourth wider than the prothorax and fully 

 twice as long; humeri not laterally prominent, but strongly oblique for some 

 distance to the base; grooves deep and strong; punctures of the interstitial 

 series moderate and not very close; male abdomen very faintly impressed 

 medio-basally, but not differently clothed. Length 2.4-2.65 mm.; width 

 1.0-1.2 mm. Brazil (Santarem). A single pair densicollis n. sp.
