Brazilian Baring 467 



a small central impunctate area; elytra a fourth longer than wide, fully a fifth 

 wider than the prothorax and very nearly twice as long, the sides moderately 

 oblique behind the broadly arcuate humeri, gradually and not obtusely rounded 

 at apex, with reentrant sutural angle; surface feebly, transversely undulated on 

 the flanks; fovese very large and deep, clearly separated; intervals with single 

 series of coarse and well separated punctures; legs moderate, the tibiae short; 

 tarsal claws long and slender. Length 11.5 mm.; width 6.0 mm. Brazil (Cha- 

 pada). October. One specimen. 



The under surface has very coarse and well separated punctures, 

 less coarse on the abdomen, where the first two segments combined 

 occupy nearly three-fifths the entire length. 



Dissopygus n. gen. 



A single species again necessitates a separate genus, as so often 

 occurs among the tropical Barinae. In this case the body is large, 

 oblong and parallel, convex, glabrous and rather shining, the elytra 

 very feebly micro-reticulate, the punctures beneath bearing very 

 fine setae. The beak is very short, thick and strongly, closely 

 punctate, not separated from the head by an impression, the 

 antennae medial, with very coarse and deep, oblique scrobes and, in 

 the male at least, the funicle is subcylindric, thick, composed of very 

 transverse joints beyond the first, which is scarcely as long as wide, 

 the club very short, scarcely as long as wide, about as wide as the 

 funicle and with its basal segment glabrous and the first suture 

 arcuate or broadly lobed medially. The prosternum is short, very 

 broadly, feebly concave, separating the coxae by half their width, 

 the posterior lobe feebly sinuate and deeply concave in posterior 

 half or more. Prothorax only very obsoletely subtubulate, the 

 basal lobe short, very broad and gradual, obtusely angulate, the 

 scutellum free, rounded, rather convex and nearly smooth. Elytra 

 broadly undulated, with deep and strong striae, bearing moderate 

 rounded foveiform punctures, the subapical transverse elevation 

 distinct. Pygidium transversely oval, densely punctate, moderately 

 convex and slightly umbonate just below the middle. First ventral 

 suture fine but evident throughout. Legs moderate, the tibiae of 

 usual length ; tarsi rather dilated, with moderate ungues. The type 

 is as follows : 



Dissopygus oblongus n. sp. — Parallel, strongly convex and moderately shining, 

 aeneous throughout; beak (o 71 ) very short and thick, feebly arcuate, not three 

 times as long as wide and scarcely over half as long as the prothorax, not com- 

 pressed, coarsely and closely but discretely punctate throughout; antennae black; 

 prothorax two-fifths wider than long, the sides parallel and strongly arcuate, 

 becoming arcuately, then sinuously, oblique to the apex, which is three-sevenths 

 as wide as the base, the disk widest at two-fifths from the base; punctures very 

 large, deep and rather well separated, with a large vacant space at each side and 

 another in the middle, all just behind the middle of the length, the middle area
