Brazilian Baring 437 



Body oblong-ovoidal, posteriorly attenuated, rather shining, the elytra alutaceous,' 

 piceous-black in color, subglabrous beneath, the pronotum with a few re- 

 motely scattered slender pale squamules, the elytra with a coarse transversely 

 zig-zag design of dense coarse linear yellowish squamules in not quite basal 

 third, and also with some scattered squamules of the same kind posteriorly, 

 more especially noticeable in a transverse line near the middle; beak thick, 

 arcuate, tapering distally, densely punctured, more finely and sparsely so 

 beyond the antennae and about as long as the prothorax, the latter two-fifths 

 wider than long, the feebly converging sides slightly arcuate, rapidly rounding 

 in about apical third to the transverse and wholly unconstricted apex; basal 

 lobe very gradual and with angulate apex; anastomosing rugae very coarse; 

 scutellum small, free, quadrate and glabrous; elytra cuneate, a third longer 

 than wide, just visibly wider than the prothorax and three-fourths longer; 

 surface very even, except that the intervals toward the suture in rather less 

 than apical half are finely carinate; grooves moderate, punctate, gradually 

 coarser basally; under surface with very coarse separated punctures, the 

 propleura obliquely rugose. Length 3.3-3.8 mm.; width 1. 7-1.9 mm. 

 Brazil (Santarem). Four specimens amazonica n. sp. 



Body more oval and less oblong, the prothorax relatively not so subquadrate, 

 shining, with opaculate elytra, the vestiture almost similar but orange-brown 

 in color and, on the elytra, extending through more than basal third; beak 

 nearly similar but relatively more elongate, somewhat longer than the 

 prothorax, the latter fully two-fifths wider than long, the sides distinctly 

 converging and broadly arcuate, very gradually more rounded anteriorly to 

 the similarly unconstricted apex, the gradually formed basal lobe very 

 different, being rather broadly rounded; rugae much less coarse but of similar 

 nature, though having a distinct narrow, feebly carinulate median smooth 

 line, not developed in the preceding species; scutellum wider and transversely 

 lunate; elytra shorter, a fourth longer than wide, more distinctly wider than 

 the prothorax, the oblique sides much more rounded but somewhat irregular, 

 the surface more uneven, having a transverse submedian and another sub- 

 apical series of short carinules; grooves much finer and very inconspicuously 

 punctate; under surface of the hind body with less coarse and closer punc- 

 tures, finer and very dense toward the sides of the abdomen. Length 3.1- 

 3.5 mm.; width 1. 5-1. 65 mm. Brazil (Santarem). Four specimens. 



amnicola n. sp. 



The anterior coxae are rather widely separated, sometimes by 

 more than their own width, but the posterior lobe of the pro- 

 sternum is very short and broadly rounded ; the intercoxal suture 

 is obliterated. 



Amphibaris n. gen. 



The unique type of this genus is a comparatively minute and 

 slender relative of Glyptobaris; the position of the beak prevents a 

 clear observation of sternal characters, but the coxae are rather 

 small and the anterior widely separated, the prosternal surface 

 apparently flat; the antennae seem to be nearly as in Glyptobaris, 

 where the small oval club is entirely pubescent. The beak is 

 rather thick, strongly punctate, moderately arcuate and separated 

 from the head by a moderate transverse impression. The prothorax 

 is distinctly though briefly tubulate at apex and with short and
