468 Memoirs on the Coleoptera 



continued to the apex by a narrow and smooth, completely coplanar line; elytra 

 about a third longer than wide, hardly visibly wider than the widest part of the 

 prothorax and two-thirds longer, the sides feebly oblique, nearly straight; apex 

 rather rapidly rounded, with large reentrant sutural angle; strial punctures deep, 

 rounded, distant and two to three times as wide as the striae; interstitial series 

 single to confused, composed of rather coarse punctures; propygidium densely 

 punctate, feebly elevated along the middle, oblique, the pygidium vertical; under 

 surface with coarse and moderately separated punctures; male abdomen with a 

 large deep basal cavity. Length 9.7 mm.; width 4.8 mm. Brazil. A single 

 specimen, sent to me without further indication of locality by Desbrochers des 

 Loges, under the name Baridius metallescens Boh. 



This species does not accord very well with the description of 

 metallescens Boh. , the expressions " linea laevi thoracis magis elevata," 

 when there is no trace of an elevated line, and "thorax latitudine 

 baseos fere longior" and "antennae * * basi testaceae," being 

 wholly irreconcilable, even though we admit that the type of 

 Boheman may be a female, where the antennas are doubtless much 

 more slender than in the male type of oblongus. 



Sclerobaris n. gen. 



The body in this genus is often almost as large as in Megalobaris 

 and is of stout, suboval form and convex, moderately shining, 

 glabrous surface. The beak is moderately long, cylindric, evenly 

 and slightly arcuate, usually very feebly bent at the point of 

 antennal insertion, separated from the head by a large and very 

 shallow impression, and is coarsely, loosely punctate, less coarsely 

 distally, especially in the female, there being very little sexual 

 difference in structure. The antennae are peculiar and very different 

 from those of allied genera, rather long and slender in the female, 

 shorter but of the same general structure in the male, the club 

 large, abrupt, elongate-oval and densely pubescent. Prosternum 

 short, with a moderate and parallel, shallow but subcanaliform 

 impression, very narrowly separating the coxae and with the posterior 

 lobe moderate and feebly sinuate. Prothorax subsinuously oblique 

 at the sides anteriorly, but not at all tubulate, the basal lobe moder- 

 ate and broadly rounded. Scutellum flat, quadrate and sometimes 

 slightly punctate, free, the elytra with coarse deep striae, which are 

 moderately and crenulately punctate. Pygidium small, semicircu- 

 larly rounded, flat, obtusely carinulate along the median line. The 

 legs are rather long and of normal structure, the tarsi with the 

 second and third joints both notably dilated, the claws very moder- 

 ate, arcuate. The first ventral suture is fine but distinct through- 

 out. The three species now in my collection are as follows: 



Color black, the elytra each with a large basal red area, gradually diminishing in 

 length inwardly, and not quite attaining the suture 2
