Brazilian Baring 165 



each in the male, having sometimes a rather short slender erect spine, 

 the two separated by the usual deep perforation. The species at 

 hand are four in number as follows: 



Elytra with scattered slender white squamules 2 



Elytra without trace of squamules, those of the under surface also almost wanting, 



except along the middle of the prosternum; body more elongate in form.. .5 



2 — Body smaller in size; male apparently with small angular prominences on 



the prosternum 3 



Body larger and stouter; male with two short and slender prosternal spines.. .4 

 3 — Form not very stout, suboval, black, shining, the prothorax piceous-black to 

 obscure rufous; beak much ( 9 ) or but slightly (cf) longer than the head 

 and prothorax, strongly, closely punctate and longitudinally subcostulate at 

 the sides, more finely punctured above; antennae rufo-piceous; prothorax a 

 third wider than long, the sides slightly converging and feebly arcuate, 

 rounding anteriorly to the deep and strongly sculptured constriction, the 

 tubulation four-sevenths as wide as the base; surface with very fine and 

 remote punctuation, excepting the very coarse sculpture in the apical con- 

 striction throughout the width, glabrous, with a few squamules on the tubu- 

 lation; basal lobe moderate but abruptly formed, truncate, having a few 

 larger punctures; scutellum as long as wide, rather free, strongly obtrape- 

 zoidal and glabrous; elytra a fourth longer than wide, parabolic, somewhat 

 narrowly rounded at tip, distinctly wider than the prothorax and three- 

 fourths longer, the humeri not prominent, oblique to the basal margin, 

 rounded and smooth; striae very coarse, abruptly and deeply grooved and 

 evidently punctate along the bottom; intervals flat, as wide as the grooves 

 to less than twice as wide, with single series of distinct but extremely remote 

 punctures bearing the squamules, a few of the latter also clustered at the 

 sides of the scutellum; under surface strongly, closely punctate, finely, 

 loosely squamulose and subalutaceous; male with a simple median impression 

 at the base of the abdomen. Length 2.6-3.0 mm.; width 1.4-1.7 mm. 

 Brazil (Chapada — forest). November. Three specimens, .dispersus n. sp. 

 Form stouter, but otherwise nearly similar in general proportion and coloration, 

 rather more polished, the squamules of the elytra longer, still more slender 

 and extremely remotely scattered, only very few in number on each elytron 

 and not clustered near the scutellum, the squamules of the under surface 

 still smaller and sparser than in dispersus; beak much thicker, arcuate, 

 densely sculptured and subopaque, much longer than the head and pro- 

 thorax in the type, the antennae almost similar; prothorax also similar but 

 sightly longer, a little more arcuate at the sides and a fourth wider than 

 long; strongly sculptured tubulation only a little over half as wide as the 

 base, the lobe and scutellum nearly similar, the latter less strongly obtrape- 

 zoidal; elytra broader, not a fifth longer than wide, parabolic, much wider 

 and three-fourths longer than the prothorax; grooves much less coarse, deep, 

 the punctures along the bottom less evident; intervals two to three times as 

 wide as the grooves and almost impunctate. Length 3.5 mm.; width 2.0 

 mm. Brazil (Rio de Janeiro). November. One specimen., micans n. sp. 

 4 — Outline broadly suboval, strongly convex, polished, deep black in color through- 

 out; beak compressed as usual, and having the sides coarsely, deeply 

 furrowed and with some punctures, all bearing very slender hair-like squam- 

 ules, moderately arcuate, distinctly longer than the head and prothorax and 

 but feebly tapering (d"), or strongly arcuate and thinner, much reduced in 

 apical half, and more than half as long as the body ( 9 ) ; antennae slender, 

 rufo-piceous, the club somewhat smaller and the basal joint of the funicle
