Brazilian Barin^e 183 



Pseudosaldius n. gen. 



The single type of this genus resembles somewhat an elongate 

 Centrinaspis, but the mandibles are curved, somewhat falciform 

 and feebly decussate, though prominent when closed. The beak is 

 long, feebly and evenly tapering throughout, very strongly, evenly 

 arcuate and arising abruptly from the head, with deep reentrant 

 angle; it is strongly, longitudinally sculptured, the median line of 

 the upper surface smooth and tumid. The antennae are medial 

 and rather slender, the funicle loose, with its first joint as long as 

 the next three, the second nearly twice as long as wide, the club 

 somewhat abrupt, elongate-oval and as long as the four preceding 

 joints. The prosternum is moderately impressed along the median 

 line, having in the male two moderate and gradually aciculate, 

 straight, erect processes, separated by the usual deep perforation, 

 the coxae approximate, separated by a fourth of their own width. 

 The legs are slender and with very even surface, the straight tibiae 

 without trace of longitudinal fluting, and the tarsi are slender, the 

 widely divergent claws well developed. The type is as follows: 



Pseudosaldius conjunctus n. sp. — Form narrowly rhomboid-suboval, black, 

 somewhat shining, the sides of the prothorax with fine separated yellowish 

 squamules, having a denuded space on the upper part of the inferior flanks, the 

 median line narrow and of similar loose squamules; elytra with confused and 

 small, dark brown squamules, with scattered Unciform squamules, more con- 

 centrated on the second interval basally and apically, and on the fourth in a 

 short line behind the middle; under surface of the hind body densely clothed 

 with uniform whiter squamules; prosternum with a herissate cluster at each 

 side of the median impression; beak with some fine sparse squamules basally, 

 distinctly more than half as long as the body, the antennae obscure testaceous; 

 prothorax barely a fourth wider than long, the sides moderately converging and 

 feebly, anteriorly gradually a little more, arcuate to the pronounced but not very 

 abrupt truncate tubulation, which is a little more than half as wide as the base; 

 punctures strong, dense, even and discrete throughout; basal lobe moderate, 

 gradual; scutellum quadrate, somewhat wider than long, coarsely punctate and 

 with a few minute squamules; elytra narrowly and evenly parabolic, a third 

 longer than wide, distinctly wider than the prothorax and not quite twice as 

 long; stria? deep and grooved; intervals flat, about three times as wide as the 

 grooves, strongly, closely and confusedly punctate; abdomen (o 71 ) convex, with 

 a very feeble impression medio-basally only a little less conspicuously squamulose. 

 Length 3.6 mm; width 1.65 mm. Brazil (Santarem). One example. 



If it were not for the mandibles, this species could be considered 

 a somewhat aberrant Centrinaspis. 



Leptosaldius n. gen. 



The body in this genus is of small size and usually rather sharply 

 rhomboidal outline, the pronotum longitudinally punctato-rugulose, 

 or sometimes almost completely smooth, the elytra strongly grooved 

 and punctate, the punctures usually bearing partial single lines of
