Brazilian Baring 425 



the joints distinctly foveate; prothorax two-fifths wider than long, the 

 strongly arcuate sides gradually straighter and subparallel basally, the 

 tubulation gradual, short and very oblique at the sides, but with the dorsal 

 constriction marked by coarse punctuation throughout; surface minutely, 

 sparsely punctulate, the basal lobe with numerous rather coarse punctures, 

 prominent and evenly rounded; elytra a little longer than wide, very obtusely 

 oval, the humeral prominences notably conspicuous; striae very fine but 

 distinct, relatively strongly punctate, all somewhat coarsely so toward base; 

 minute, sparse interstitial punctulation evident; pygidium moderately and 

 loosely punctate; abdomen (o") moderately impressed at base, the fifth 

 segment with two deep confluent fovea?, the edge behind them prominently 

 lobed at the middle, or ( 9 ) unimpressed and with two smaller fovea? on the 

 fifth ventral, which are narrowly separated — by half their width, the apex 

 even and not lobed; prosternum broadly concave, separating the coxae by 

 their own width, the strongly convex lobe divided by a deep median channel. 

 Length 6.2-7.0 mm.; width 4.2-4.65 mm. Brazil (Chapada — campo). May 



and October. Nine specimens suffusus n. sp. 



14 — Body elongate-oval, bright polished and uniform green throughout the body, 

 legs and beak, the latter thick, not compressed, finely, sparsely punctate, 

 nearly straight, slightly bent at the antennae and distinctly shorter than the 

 prothorax; antennae but little beyond the middle; prothorax nearly one-half 

 wider than long, the converging sides almost straight, strongly rounding 

 beyond the middle, the tubulation abrupt; surface smooth, the basal lobe 

 prominent and evenly rounded; elytra much more elongate than usual, a 

 third longer than wide and two-thirds longer than the prothorax; striae very 

 fine but sharply defined, finely, remotely punctate; pygidium shorter and 

 more transverse than usual, rather convex, fully twice as wide as long and 

 finely, sparsely punctate; fifth ventral devoid of foveation in either sex, the 

 apex (o 71 ) shallowly sinuate medially, with a short and gradually formed lobe 

 projecting from the middle of the sinus. Length 6.4-6.9 mm.; width 3.5-4.0 

 mm. Venezuela. Three specimens chevrolati Chmp. 



Included above, with such other neotropic species as are at hand, 

 are a number of species from the Central American region, which 

 have been in my collection for many years; these all belong to the 

 festivus section of the genus, characterized by the evident irregular 

 impression at the base of each elytron, but in every case they prove 

 to be unquestionably distinct species, if I have correctly identified 

 festivus; my festivus may, however, be viridis Boh., although this 

 does not seem probable, in view of the apparently very moderate 

 humeral prominences ascribed to the latter; in the species which I 

 have identified as festivus, the humeral prominences are conspicuous. 

 Yucatecus Chmp., is another of these allies of festivus, but it differs 

 however in its dark and cupreous-brown coloration, among other 

 features. The prosternal characters of cavilobus, puncticollis and 

 some others, form excellent specific criteria, and the thoracic 

 sculpture of puncticollis and gramineus is peculiar. Perhaps flatu- 

 arius Germ., may come near the two latter, but the beak is said to 

 be dark at apex in that species. 



Eurhinopsis Chmp.
