Brazilian Baring 319 



Aniops n. gen. 



The body is here small, narrowly suboval, strongly convex, 

 sparsely squamulose and very coarsely and closely punctato-rugose. 

 The beak is very short and thick, at least in the male, densely and 

 strongly sculptured and not separated by a distinct impression. 

 Antennae very short, medial, the scrobes deep and very oblique, the 

 funicle rather slender, the club stout, oval, abrupt, only sparsely 

 pubescent and with its first segment very large, about three-fourths 

 the mass. The coxae are small, the anterior larger and narrowly 

 separated. The legs are short but slender, nearly normal, the tarsi 

 unusually narrow, with feebly dilated third joint and moderate 

 connate claws. The prothorax is not tubulate at apex and is 

 broadly rounded medially at base, the scutellum small, rough and 

 emarginate at tip and the elytra deeply and coarsely sulcate, with 

 narrow and sharply convex intervals. The type may be described 

 as follows: 



Aniops sculpturata n. sp. — Elongate-suboval, very convex, dull and coarsely, 

 very conspicuously sculptured, black, the legs rufo-piceous, the elytra pale 

 rufous; squamules whitish, very slender and sparse on the pronotum, shorter 

 and thicker and close-set in single lines along the summit of the interstrial 

 ridges, which are alternately well marked and more feebly developed, the under 

 surface with small and slender sparse squamules, not closer on the met-episterna; 

 beak thick, dull, densely sculptured, feebly arcuate and three-fourths as long as 

 the prothorax, which is not quite as long as wide, the subparallel sides broadly 

 arcuate, a little more oblique at the truncate apex, which is fully three-fourths as 

 wide as the base; punctures very coarse, deep and dense; elytra three-fourths 

 longer than wide, the sides parallel and straight for three-fifths, then rounding 

 and oblique to the narrow apex, with individually rounded apices, a fourth wider 

 than the prothorax and between two and three times as long, the humeri but 

 feebly swollen, the sides thence rapidly oblique to the base; sulci very coarse 

 and deep, punctate; intervals very convex, costiform and but little wider than 

 the sulci, the surface rather dull; abdomen with small and well spaced punctures, 

 rather dull and having, medio-basally, a deep impression, extending almost to 

 the apex of the second segment. Length 2.25 mm.; width 0.8 mm. Brazil 

 (Chapada — forest). August. A single male specimen. 



This is among the more isolated types in the Limnobarini. 

 Completely covered pygidium, non-tubulate prothorax, approxi- 

 mate coxae, connate claws and many other features prevent any 

 close comparison between Aniops and the nearctic Desmoglyptus. 



Psiona n. gen. 



A genus, of wide distribution in Brazil, is necessary for a moderate 

 number of elongate-suboval, more or less opaque, glabrous and 

 densely punctate small species, with short and opaque, barely 

 arcuate beak, not separated from the head by an obvious impres- 

 sion. The antennae are beyond the middle, short but not very
