ium, will easily serve to distinguish this genus from the preceding, 

 with which, however, it forms a small definite section in the Barini. 



Liobaridia n. gen. 



The body here is evenly and rather broadly oval, convex, polished, 

 feebly sculptured and glabrous, the prothorax briefly tubulate at 

 apex, with large and prominent, narrowly rounded basal lobe, small, 

 close-set, ogival scutellum, deeply and sharply grooved elytra and 

 small, subeven and densely sculptured, semicircular pygidium; the 

 first ventral suture is fine but distinct throughout the width. The 

 beak is rather long, slender, arcuate, feebly separated from the front 

 and is swollen above basally, a character often appearing in the 

 Pseudobarid series. Antennae submedial, slender, with long scape, 

 the first funicular joint as long as the next three, the club oval, 

 very abrupt and as long as the four preceding joints, the first and 

 second segments each nearly two-fifths the mass. The prosternum 

 is very broadly and deeply canalate, the canal ending abruptly at 

 the intercoxal suture, the lobe moderate and medially sinuate at 

 apex; the coxae are separated by fully their own width. The legs 

 are well developed, normal, with notably long, slender tarsi and 

 contiguous straight claws. The type is as follows: 



Liobaridia rostrata n. sp. — Oval, convex, polished and deep black, completely 

 glabrous; beak ( 9 ) slender, nearly half as long as the body, the antennae slender, 

 piceous; prothorax a third wider than long, the sides distinctly converging and 

 virtually straight, gradually moderately rounding beyond the middle, the tubu- 

 lation more than half as wide as the base; punctures minute and very sparse, 

 gradually rather strong but sparse laterally; elytra oval, moderately obtuse at 

 apex, a fourth longer than wide, at the large and feebly tumid humeral swellings 

 slightly wider than the prothorax, three-fourths longer, feebly umbonate sub- 

 apipally, the surface broadly biundulate at the sides; grooves deep, obscurely 

 punctulate, a third as wide as the sparsely and infinitesimally punctulate intervals, 

 coarsely exarate-apically; under surface strongly, sparsely punctate, the abdomen 

 finely and remotely; tarsi as long as the tibiae. Length 4.25 mm.; width 2.0 

 mm. Brazil (Chapada — forest). May. A single female. 



Distinguishable among the other allies of Pseudobaris, by the long 

 beak, broad deep prosternal canal, abruptly ending at the suture, 

 and widely separated coxae; also by the very feeble sculpture. 



Linoma n. gen. 



This genus is related rather closely to Heterosternus, but differs 

 in facies due to the more elongate form, relatively smaller prothorax, 

 sparse and fine sculpture and very slender beak; the tarsi are short, 

 with relatively long strigose and basally subconnate claws. The 

 antennae are inserted slightly (c?) or much ( 9 ) behind the middle 

 of the beak, short, the club small, very short and broad, only
