Brazilian Barin/E 245 



section; antennae similar, piceous, the scape extending more than half way 

 to the eye, the club well developed; prothorax a third wider than long, the 

 sides converging and straight, more oblique in apical two-fifths, the feebly 

 tubulate apex half as wide as the base; punctures rather coarse, very close; 

 scutellum small, squamulose; elytra barely a fourth longer than wide, the 

 oblique sides broadly arcuate, the apex narrowly rounded, with reentrant 

 sutural angle, scarcely twice as long as the prothorax; grooves rather narrow, 

 deep, the intervals somewhat coarsely and closely punctate; anterior coxae 

 separated by half their width; transverse prosternal constriction deep and 

 at a considerable distance from the apex. Length 3.0 mm.; width 1.6 mm. 

 Brazil (Santarem). One female specimen intrita n. sp. 



Body feebly subrhombic-oval, black throughout, the surface opaque where 

 exposed; slender squamules pale yellow, scattered over the pronotum, with 

 an oblique sublateral vitta and median line conspicuous and of closer squam- 

 ules, these also almost as close broadly at the sides, rather close on the elytra, 

 except subbasally and toward the suture; broad, white and very dense 

 beneath; beak (9) differing from any of the preceding, very slender and 

 smooth, enlarging slightly at the extreme base, not flattened, strongly and 

 evenly arcuate and longer than the elytra; antennae slender, rufous, just 

 beyond basal third, the scape almost attaining the eye; first funicular joint 

 as long as the next two, which are both elongate; club missing in the type; 

 prothorax nearly a third wider than long, the sides feebly converging and 

 feebly, subevenly arcuate to apical third, there more rounding to the scarcely 

 at all tubulate, truncate apex, which is less than half as wide as the base, 

 punctures coarse but not deep, dense; scutellum well developed, clothed 

 very densely, as also the lobe, with long and more whitish squamules; elytra 

 fully a third longer than wide, the oblique sides evenly and broadly arcuate, 

 the apex very narrowly rounded, not quite twice as long as the prothorax; 

 grooves moderate; intervals rather roughly punctate; legs densely albido- 

 squamose. Length 4.0 mm.; width 2.15 mm. Brazil (Santarem). One 

 female example canonica n. sp. 



Body suboval, with relatively larger prothorax, black throughout; squamules 

 very thin and slender, pale yellowish, loosely and subevenly distributed over 

 the entire pronotum, very remotely scattered over posterior two-thirds of 

 the elytra, a little closer thence basally, rather narrowly close on the first 

 interval to behind the middle and along the fourth and fifth near apical 

 third, whiter and not very broad, but dense, over the entire under surface; 

 beak (9) piceous, smooth, very slender, thickening slightly at the extreme 

 base, evenly and moderately arcuate and somewhat longer than the elytra, 

 flattened and gradually broader apically above; antennae piceous, rather 

 long, slender, at basal third, the scape almost impinging upon the eye; first 

 funicular joint as long as the next two, the second also elongate; club notably 

 long and very slender, more than twice as long as wide; prothorax a third 

 wider than long, the sides almost parallel and nearly straight for two-thirds, 

 then rapidly oblique to the apex, which is about half as wide as the base; 

 punctures coarse, deep and dense, the lustre dull as in the preceding; scu- 

 tellum and lobe nearly as in canonica; elytra also nearly similar throughout, 

 but shorter, three-fourths longer than the prothorax; legs more finely and 

 not so densely squamulose. Length 3.68 mm.; width 1.85 mm. Brazil 

 (Santarem). One female specimen particeps n. sp. 



8 — Form rather narrowly rhombic-oval, black throughout and alutaceous, the 

 large and parallel pale pronotal squamules in great part denuded in the 

 type, but apparently abundant laterally and apically and largely wanting 

 basally, the scutellum small, quadrate, subglabrous and feebly impressed, 

 the yellowish parallel scales of the elytra in great part denuded in the type,
