Brazilian Baring 475 



sides, very broadly and obtusely rounded at apex, scarcely a fifth longer 

 than' wide, distinctly wider than the prothorax and about twice as long; 

 surface strongly, transversely undulate, strongly and transversely elevated 

 subapically, the fine striae dilated and impressed at base and very coarsely, 

 deeply impressed apically, the intervals having sparse and uneven punc- 

 tures, notably fine suturally. Length 7.5 mm.; width 4.0 mm. Brazil 

 (Rio de Janeiro). October. One specimen chalybea n. sp. 



Body narrower, more or less cupreo-aeneous in lustre throughout, the antennae 

 paler; pronotum with a deep discal fovea at each side 2 



2 — Body obscure aeneous to blackish, oblong, polished; beak (9) very short, 

 thick, strongly arcuate, between two and three times as long as wide, with 

 very coarse deep irregular punctures, separated by narrow shining inter- 

 spaces; front with a simple feeble impression; antennae short, fuscous, 

 gradually paler basally; prothorax two-fifths wider than long, the sides 

 parallel and arcuate, rapidly rounding and convergent at apex to the strong 

 and wide tubulation; punctures coarse, dense and rugose at the sides, very 

 irregularly remote discally, without well defined median impunctate line; 

 scutellum smaller, subquadrate; elytra oblong, very obtusely rounded at 

 apex, a fifth longer than wide, not quite twice as long as the prothorax; 

 surface extremely and deeply undulated, the fine sharp striae much dilated 

 at base and very coarsely deep and exarate behind in crossing the subapical 

 transverse elevation. Length 6.5-7.0 mm.; width 3.3-3-6 mm. Brazil 

 (Rio de Janeiro). October. Two specimens. [Baris monstrosa Germ.] 



monstrosa Germ. 



Body slightly more elongate, very bright cupreo-aeneous throughout; beak ( 9) 

 still shorter and nearly straight, very thick and but little over twice as long 

 as wide, very densely punctate, setulose and longitudinally substrigose, 

 opaculate; front with a narrow longitudinal impression joining the shallow 

 transverse impression at the base of the beak; antennae short, ferruginous 

 throughout; prothorax ( 9 ) nearly as in the preceding but more transverse, 

 and with a much broader tubulation, this being more than half as wide as 

 the base; punctures similarly very unequally remote, but distinctly less 

 coarse; scutellum larger, transversely quadrate; elytra nearly similar but 

 fully a fourth longer than wide, wider than the prothorax and fully twice as 

 long; surface rather less strongly undulated; striae very fine and sharply 

 defined, similarly enlarged at base and apex but, discally, finer than in 

 monstrosa. Length 6.2-7.0 mm.; width 2.8-3.4 mm. Brazil. Two speci- 

 mens, from Desbrochers des Loges. [Baridius impressifrons Boh.] 



impressifrons Boh. 



In monstrosa and impressifrons, the third strial interval is tuber- 

 cularly tumid at apex; there is no trace of this in chalybea, nor of 

 the deep discal fovea at each side of the pronotum. 



Glyptobaridia n. gen. 

 This genus is allied rather closely to Baris, but differs in having 

 the beak separated from the head by a narrow abrupt sulcus. The 

 body is oblong-oval, convex, coarsely, densely sculptured and sub- 

 opaque, with erect and bristling setae and narrow erect squamules. 

 Beak rather short and thick, strongly sculptured, the antennae 

 slightly post-medial, moderate in length, with rather long first 

 funicular joint and stout oval club, as long as the three or four
