Brazilian Barinje 279 



beak ( 9 ) rather strongly arcuate and moderately slender, longer than the 

 prothorax and with the antennae barely beyond the middle, the beak longer 

 and the antennae less ultra-median than in the female of diversus; prothorax 

 of different outline, fully a third wider than long, the sides parallel and 

 feebly arcuate, rapidly rounding and converging in only apical third; punc- 

 tures similar but much less close, separated by their own widths or more; 

 elytra subsimilar, but rather more obtusely rounded behind and more than 

 twice as long as the prothorax, the abrupt grooves a little coarser, the rather 

 coarse interstitial punctures more evenly uniserial. Length 2.9 mm.; width 

 1.3 mm. Brazil (Santarem). One specimen recticollis n. sp. 



5 — Body somewhat broadly 'oval, piceous-black, with slightly reddish legs, 

 clothed throughout above with narrow and moderately dense yellowish 

 scales, confused on all the strial intervals, not much paler but shorter and 

 denser beneath, the surface closely punctate, without smooth pronotal line; 

 beak (o 71 ) moderately slender, feebly compressed and distinctly sculptured 

 at the sides, evenly arcuate and as long as the head and prothorax, or ( 9 ) 

 but very little less thick and very little longer, less compressed at the sides; 

 antennae medial (9), near three-fifths (o 71 ); prothorax a third to two-fifths 

 wider than long, the sides subparallel in basal, converging in apical, half; apex 

 less than half as wide as the base; scales even, not very dense and oblique 

 in direction; dense scales of the scutellum not much paler; elytra oval, a 

 fourth to third longer than wide, slightly wider than the prothorax and 

 nearly two and one-half times as long; striae rather coarse, deep and nude; 

 first interval with uniseriate scales; male abdomen with dense scales, just 

 visibly impressed but scarcely less squamose medio-basally; anterior coxae 

 separated by less than a third their width. Length 2.5-2.85 mm.; width 

 1. 2-1. 45 mm. Brazil (Chapada — forest). August and September. Eight 

 specimens gilvivestis n. sp. 



Body smaller, much more narrowly oval, piceo-rufous, with rufous tibiae; punc- 

 tures moderate and close-set, the pronotum without smooth line; upper 

 surface very uniformly clothed with narrow and well separated scales, 

 yellowish-white in color and sublongitudinal on the pronotum, the latter 

 without smooth line; the scales beneath are whiter and broader, close-set 

 but fine and shorter, though equally close, on the abdomen; beak (9) 

 rather smooth, shining, more punctured and squamose only at the extreme 

 base, evenly arcuate, somewhat slender and a little longer than the head 

 and prothorax; antennae rufous, medial; mandibles each with a small nick 

 internally near base, the margin straight; prothorax barely a third wider 

 than long, the sides subevenly arcuate, gradually becoming nearly parallel 

 basally, the truncate apex half as wide as the base, the lobe and scutellum 

 more densely squamose as usual; elytra evenly elongate-elliptic, three- 

 sevenths longer than wide, only a little wider than the prothorax and between 

 two and three times as long; striae coarse; interstitial punctures rather 

 loosely confused. Length 2.35 mm.; width 1.0 mm. Brazil (Santarem). 

 One example rufescens n. sp. 



Body more broadly oval, almost as in gilvivestis in color, sculpture and pale 

 fulvous-yellow vestiture, but smaller, narrower and with the prothorax 

 slightly less abbreviated, a fourth to third wider than long and with its 

 sides more gradually rounding and converging anteriorly, not parallel but 

 slightly oblique in about basal half; beak differing very much, very thick, 

 strongly compressed, feebly, evenly arcuate, distinctly sculptured and rather 

 longer than the head and prothorax (d<), or moderately slender, shining, 

 scarcely compressed and less sculptured, evenly arcuate, a third longer than 

 the head and prothorax and slightly thinner distally ( 9 ) ; antennae medial 

 ( 9 ), at fully three-fifths (d 1 ), nearly as in gilvivestis, but with the sublongi-
