464 Memoirs on the Coleoptera 



subequal in thickness throughout and shining, the antennae blackish; prothorax 

 a third wider than long, the converging sides moderately and evenly arcuate 

 throughout; apex more than half as wide as the base, the surface feebly impressed 

 transversely near apex; punctures coarse, deep and slightly separated laterally, 

 smaller and separated by nearly twice their widths medially, without smooth 

 line; elytra a fourth longer than wide, very obtuse at apex, the sides but feebly 

 oblique, more than a fourth wider than the prothorax and much more than twice 

 as long; grooves even, not distinctly punctate; intervals with single series of 

 fine, transversely lunate punctures, each bearing a minute hair; abdomen almost 

 impunctate medially, with the first suture obliterated. Length 2.3 mm.; width 

 1.0 mm. Brazil (Santarem). One specimen. 



Brachylinoma is evidently in the same group of genera as the 

 preceding, but it differs in the entire form and facies of the body, 

 in the character of the elytral striation, absence of apical tubulation, 

 much shorter legs and rather different character of the beak. 



Giveniopsis n. gen. 



Another genus of this Pseudobarid group seems to be demanded 

 by some minute obscure forms, with oblong-suboval outline and 

 conspicuous setiform squamules sparsely clothing the body. The 

 beak is somewhat as in the preceding, moderately slender, even in 

 thickness, cylindric and strongly, evenly arcuate, but it is less 

 strongly separated from the head and is smooth, having minute, 

 sparse punctures throughout. Antennae variable, the club small, 

 rather abrupt, narrowly oval and scarcely over half as long as the 

 stem in typical species. Prosternum with a rather narrow, deep 

 and very sharply defined canal, the posterior lobe broadly arcuate. 

 Legs moderate, the femora straight; tibiae moderate, the slender 

 tarsi shorter than the tibiae; claws connate. Prothorax relatively 

 very moderate in size, briefly tubulate at apex as a rule, the basal 

 lobe small, rounded. Scutellum small, subpentagonal, with raised 

 edges; elytra each broadly, evenly rounded at tip, the grooves 

 rather fine; pygidium small, semicircular, feebly convex. Abdomen 

 differing in having the first suture fine but distinct, narrowly sub- 

 obsolete at the middle. The species are moderately numerous, 

 those at hand being as follows: 



Form oblong, stout, the antennal club very small; serial punctures of the elytra 

 shallowly concave. Black, with rufo-piceous legs, the setiform squamules 

 conspicuous; beak (9) moderately slender, evenly and strongly arcuate, 

 cylindric, minutely, sparsely punctate, gradually strongly so basally, some- 

 what longer than the head and prothorax; antennae evidently behind the 

 middle, rufo-piceous, rather slender, the first funicular joint as long as the 

 next three, the club narrowly oval, abrupt and only as long as the preceding 

 four joints; prothorax fully a fourth wider than long, the feebly converging 

 sides almost straight, rounding apically; apex more than half as wide as the 

 base; punctures moderate, deep, very close throughout; elytra oblong, only 

 a fourth longer than wide, a fifth wider than the prothorax and more than
