Brazilian Baring 201 



and converging to the distinct truncate tubulation, which is fully half as 

 wide as the base; punctures throughout very coarse, deep and subeven, 

 separated by about their own widths, close laterally but not evidently 

 confluent, without smooth median line; basal lobe very short and broadly 

 rounded; scutellum very free, parallel, longer than wide, subemarginate and 

 very feebly impressed, glabrous; elytra a fourth longer than wide, parabolic, 

 with feeble reentrant angle at the suture, wider than the prothorax and not 

 quite twice as long; grooves very coarse, deep, strongly punctate along the 

 bottom and only a little narrower than the intervals; punctures of the single 

 interstitial series moderately coarse and rather close-set; under surface 

 strongly, subevenly punctate and very coarsely so throughout the inferior 

 flanks of the prothorax. Length 27-3.0 mm.; width 1. 3-1 .45 mm. Brazil 



(Santarem). Four specimens fluminalis n. sp. 



Body nearly as in the preceding but larger and distinctly more elongate; lustre 

 similar; color more nearly black; beak (9) and antennae nearly similar, 

 the club a little larger; prothorax a fourth wider than long, the converging 

 sides nearly straight, gradually rounding and converging anteriorly to the 

 feebler tubulation, which is distinctly less than half as wide as the base and 

 very much narrower and less pronounced or constricted than in fluminalis, 

 the sculpture nearly similar, the squamules less numerous; scutellum even 

 more elongate; elytra longer, nearly a third longer than wide, parabolic, 

 with still feebler and more broadly arcuate humeri and fully twice as long 

 as the prothorax; sculpture almost similar, the strial punctures not quite so 

 conspicuous, the squamules of the single series somewhat finer and shorter 

 and with more extensive admixture of darker squamules; in fluminalis they 

 are nearly all of a pale yellowish tint; under surface nearly similar. Length 

 3.35 mm.; width 1.6 mm. Brazil (Santarem). One female specimen. 



mixtus n. sp. 

 3 — Body rather stout and shining, piceous; beak moderately and evenly arcuate, 

 a little longer than the head and prothorax in both sexes, cylindric, feebly 

 ( 9) or scarcely at all (o 71 ) tapering from base to apex, gradually closely 

 punctate basally, more especially in the male and feebly gibbous above at 

 the sulcus; antennae obscure testaceous, the club small, oval; prothorax a 

 fourth wider than long, the converging sides nearly straight to apical third, 

 there rapidly rounding to the pronounced tubulation, which is not quite 

 half as wide as the base; punctures coarse and sparse, a little less sparse 

 laterally, with closer and less coarse punctures medially and a broad distinct 

 entire median impunctate line, the basal lobe obtusely cuspidiform, short; 

 scutellum free, glabrous, quadrate; elytra evenly parabolic, a fourth longer 

 than wide, over a fourth wider than the prothorax and much more than 

 twice as long; humeri slightly prominent; grooves very coarse, with strong 

 punctures along the bottom; intervals equal in width to the grooves, each 

 with a single series of strong and well spaced punctures, the suberect slender 

 squamules yellowish or sometimes intermingled with some that are smaller 

 and darker, very fine, remote and inconspicuous on the pronotum; under 

 surface closely, rather strongly punctured and with very small slender pale 

 squamules. Length 3.75-4.0 mm.; width 1. 75-1 .85 mm. Brazil (Chapada). 

 On flowers near the forest. March and November. Eight specimens. 



inaequalis n. sp. 

 Body nearly as in the preceding in color, lustre and general structure, but smaller 

 and narrower, the beak and antennae almost similar in both sexes; prothorax 

 shorter, about a third wider than long, the converging sides a little more 

 arcuate and more noticeably, though very gradually so, beyond about the 

 middle, rounding a little less rapidly apically to the somewhat similar tubu- 

 lation; punctures and long fine, very sparse squamules nearly similar, the
