inner edge perfectly straight. The antennae are medial or somewhat 

 behind the middle, moderate in length, the first two funicular joints 

 subequal and notably elongate, the others rather short, not much 

 thicker distally, the club thick and oval, with the basal segment 

 large, much more than half the mass, and becoming glabrous at 

 base. The prosternum is flat, broadly truncate behind, abutting 

 closely against the mesosternum, and is not armed in the male; it 

 separates the coxae by about one-half more than their width. The 

 legs are moderate, with mutic femora and shorter straight fluted 

 tibiae, the tarsi slender, with feeble third and long fourth joint, the 

 claws long, free and diverging. The prothorax is briefly tubulate 

 at apex, with small and feebly rounded basal lobe, the scutellum 

 free, small, as long as wide and obtrapezoidal, and the elytra are 

 deeply grooved, the grooves in some species very coarsely punctate. 

 The known species are as follows: 



Elytral grooves coarsely punctate, the pronotum with a dense confused mixture 

 of very coarse to less coarse punctures 2 



Elytral grooves not coarsely punctate, except at the sides; pronotal punctures 

 finer and sparser; body broader and more depressed 3 



2 — Body elongate-oval, rather convex, somewhat shining and nearly glabrous, 

 the elytra with single series of rather long, erect and stiff, yellowish setae, 

 the pronotum with a few shorter setae at the sides, the under surface with 

 small sparse squamules, almost obsolete on the abdomen; color umber 

 brown, more rufous beneath; beak in the type nearly straight, tapering 

 and smoother distally, rapidly bent at apical third, as long as the prothorax, 

 sculptured and setulose basally, the antennae slightly behind the middle; 

 prothorax a fourth wider than long, the subparallel sides broadly and feebly 

 arcuate, more reapidly rounding anteriorly to the tubulation, which is half 

 as wide as the base; larger punctures very coarse; fine median line subtumid, 

 obsolete anteriorly; elytra a third longer than wide, very evenly ogival, 

 with obtuse apex, nicked at the suture, nearly a fourth wider than the pro- 

 thorax and a little more than twice as long, the humeri slightly prominent; 

 grooves more than half as wide as the intervals, which have each a series of 

 coarse but very shallow, indistinctly defined punctures; abdomen convex, 

 finely, loosely punctulate, the fifth segment densely so. Length 3.0 mm.; 

 width 1.25 mm. Brazil (Santarem). One specimen sculpticollis n. sp. 



Body almost similar but shorter, nearly similar in color, lustre and vestiture; 

 beak almost similar, but evidently longer than the prothorax, which is 

 rather more than a fourth wider than long, the sides more strongly arcuate, 

 becoming gradually parallel in about basal half; larger punctures having 

 about half the individual area of those of the preceding species, the median 

 subtumid line smoother and better defined, but obsolete toward base and 

 apex; elytra shorter, less than a third longer than wide, ogival, but with 

 more obtuse apex and more strongly arcuate sides, barely a fifth wider than 

 the prothorax and only one-half longer; sculpture nearly similar; abdomen 

 convex, similar and with a feeble medio-basal impression, which may indicate 

 the male, and also evident though feebler in the type of the preceding species. 

 Length 2.75 mm.; width 1.18 mm. Brazil (Santarem). One specimen.
