Brazilian Baring 243 



Ground scales of the elytra rather bright fulvous; white scales closely aggregated 

 on intervals one and two in nearly basal half, forming a conspicuous parallel 



plaga 8 



3~ -Pronotal punctures sparse, or at least distinctly separated 4 



Pronotal punctures dense 7 



4 — Sides of the prothorax converging from the base 5 



Sides becoming parallel in about basal half 6 



5 — Body rhombic-oval, convex, black and shining, the legs, beak and spines 

 black. Male with the beak rather thick, cylindric, long and very strongly 

 arcuate, separated from the head by a large deep reentrant angle, punctured 

 and longitudinally, feebly furrowed, cylindric and fully as long as the elytra; 

 antennae moderate, blackish and medial; prothorax scarcely a sixth wider 

 than long, conical, with broadly and evenly arcuate sides, the distinct apical 

 tubulation less than half as wide as the base; punctures sparse and very 

 shallowly impressed, wanting basally; pale squamules long and very slender, 

 extremely remote and without order; scutellum smooth and glabrous; 

 elytra nearly a third longer than wide, the oblique sides moderately arcuate, 

 the apex rather strongly rounded, scarcely twice as long as the prothorax; 

 grooves deep; intervals distinctly but loosely subbiseriately punctate; under 

 surface with well separated small brownish squamules; abdomen not dis- 

 tinctly modified; prosternal spines long, straight, parallel and much longer 

 than the prothorax, separated by a simple glabrous canaliculation. Female 

 smaller than the male, similar in color and almost as shining, the beak 

 shorter and less arcuate, more arcuate basally than apically, a little more 

 tapering, three-fourths as long as the elytra, the antennae similar and medial; 

 prothorax much shorter, a third wider than long, subsimilarly conical, but 

 with the punctures more numerous, rather coarser and especially much 

 deeper; elytra nearly as in the male but much more than twice as long as 

 the prothorax, similarly with the pale slender squamules sparsely scattered, 

 subunilineate, more abundant suturally toward base; anterior coxae similarly 

 narrowly separated. Length (a 71 ) 3.5-3.8 mm., ( 9 ) 3.3-3.5 mm.; width (o 71 ) 

 1.7-2.0 mm., ( 9) 1.6-1.8 mm. (8 d\ 6 9). Brazil (Santarem). 



laevicollis n. sp. 

 Body (6") almost similar throughout, but a little smaller and somewhat narrower; 

 beak nearly similar, but scarcely so thick and a little more tapering, very 

 arcuate and somewhat longer than the elytra, the piceous antennae at the 

 middle, the scape similarly short and not extending quite half way to the 

 eye; prothorax fully a fifth wider than long, conical, the sides broadly, 

 subevenly arcuate; apex fully half as wide as the base; punctures twice as 

 numerous, rather smaller but more deeply impressed, not so completely 

 obsolete basally, but becoming very minute; squamules slender, slightly 

 fulvous, almost wanting except in three narrow and loosely aggregated 

 vittae, which become obsolete in nearly basal half; scutellum smaller and 

 much narrower, parallel and longer than wide, not transversely obtriangular 

 as in the preceding; elytra similar but still more narrowly rounded at apex, 

 not quite twice as long as the prothorax; striae deep, the intervals loosely 

 punctate, with a few long slender yellowish squamules, more closely aggre- 

 gated in subbasal and apical lines on the second interval, and more or less 

 short lines on intervals 4-6 behind the middle; under surface with broader 

 whitish scales, very dense and unlike those of the preceding, the abdomen 

 (0 71 ) flattened and less squamose medio-basally, the prosternal spines straight, 

 oblique and much longer than the prothorax. Length 3.35 mm.; width 



1.8 mm. Brazil (Santarem). One example obnixa n. sp. 



A — Body (o 71 ) very much as in obnixa but narrower, the long slender yellowish 

 squamules forming three entire, very loose pronotal vittae, similarly arranged
