the head and prothorax; antennae blackish, short, medial, inserted on the 

 inferior surface and with very short scape and short, broadly oval club; 

 prothorax two-fifths wider than long, the sides parallel in basal, oblique in 

 apical, half, the truncate apex fully half as wide as the base; elytra parabolic, 

 a fifth longer than wide, three-fourths longer than the prothorax; legs 

 piceous. Length 3.2 mm.; width 1.4 mm. Brazil (Chapada — campo). 



October. A single female elegans n. sp. 



Scales of the elytra more or less nebulously variegated 13 



13 — Vestiture pale ochreous in color 14 



Vestiture white or nearly so; species much smaller 15 



14— Body oval, black; beak cylindrical, very evenly and rather strongly arcuate 

 in both sexes, two-thirds as long as the elytra and strongly, very densely 

 punctate basally (o 71 ), or not quite so stout, smooth, finely and sparsely 

 punctate and three-fourths as long as the elytra ( 9 ) ; antenna; piceous, 

 moderately long, medial ( 9 ) or slightly beyond (o 71 ); prothorax two-fifths 

 to nearly half wider than long, the sides strongly, subevenly arcuate, almost 

 parallel basally, the punctures strong and dense; parallel scales transverse, 

 somewhat dense, sometimes rather denuded medially, uniform; elytra 

 triangular, with strongly arcuate sides and narrow apex, a fourth longer than 

 wide and less than twice as long as the prothorax, the squamules loosely 

 distributed, but denser in the scutellar and basal sutural region, and in the 

 usual subsutural quadrate areas just behind the middle; male with two 

 straight, very slender and moderate prosternal spines, the inner edge of the 

 anterior tibiae loosely fringed, the hairs barely longer than the thickness of 

 the tibia; legs piceous. Length 2.75-3.0 mm.; width 1. 35-1 .6 mm. Brazil 



(Santarem). Three specimens propinqua n. sp. 



Body in most respects almost exactly as in the preceding, the form and vestiture 

 almost similar; beak (o 71 ) longer and smoother, strongly, evenly arcuate and 

 fully three-fourths as long as the elytra, the punctures distinctly separated; 

 antennae rufous, prothorax nearly similar in form and vestiture, the trans- 

 verse scales, however, not quite so broad; elytra nearly similar, but with 

 much less or obsolescent reentrant angle at the suture and with somewhat 

 coarser grooves; male with similar very slender and rather short prosternal 

 spines, and wholly unmodified surface between them, the anterior tibiae 

 loosely fringed within, but with the hairs very much longer, being more 

 than twice as long as the thickness of the tibia. Length 2.7-2.85 mm.; 

 width 1. 35-1. 45 mm. Brazil (Chapada). October and November. Three 



male specimens thespis n. sp. 



Body subsimilarly oval but with relatively longer prothorax and broader 

 scales, forming a dense crust above and beneath, the latter whiter; pronotal 

 scales a little darker and not quite so wide medially; on the elytra they are 

 pale fulvous, whiter in a triangular basal and subtransverse post-medial 

 area, and also toward the sides, but subequally dense throughout; beak 

 almost similar in the sexes and strongly, evenly arcuate, about as long as the 

 head and prothorax, a little more tapering distally but similarly smooth, 

 rather densely squamose thence to the base; antennae medial ( 9 ), a little 

 beyond (o 71 ), blackish and rather short, the club stout; prothorax scarcely 

 a third wider than long, the sides feebly converging and barely arcuate, 

 becoming gradually more arcuate anteriad, somewhat strongly, very densely 

 punctate and opaque where exposed; elytra oval, scarcely a fifth longer 

 than wide, three-fourths longer than the prothorax, the humeri as usual in 

 this section — obtusely and slightly prominent; striae moderate, narrowly 

 dividing the squamose crust; male with two very slender, outwardly curved 

 prosternal spines, about half as long as the prothorax, with no evident 

 impression between them, the abdomen feebly impressed and less squamose
