Brazilian Barin/e 169 



strongly dilated and clothed with close brown to golden hairs. 

 The prothorax is more or less gradually subtubulate at apex, with 

 the basal lobe moderately long and abrupt, strongly rounded at 

 apex and usually with a feeble basal impression at each side. There 

 are four species in my collection as follows: 



Prosternum flat, densely and uniformly clothed with long and subherissate, 

 yellowish squamules 2 



Prosternum rather closely clothed, but feebly channeled, with a deeper excavation 

 anteriorly 3 



2 — Form rhombic-oval, moderately convex, deep black throughout, the upper 

 surface glabrous, excepting the posterior elytral spot of dense whitish scales, 

 which is short and subquadrate; under surface glabrous, the prosternum, 

 mesosternum, mes-epimera and sides of the first two ventral segments 

 abruptly very densely clothed throughout with yellowish-white scales; beak 

 but slightly longer than the head and prothorax, strongly punctured, some- 

 what strongly arcuate and subequal (o 71 ), or a little less arcuate, just visibly 

 longer, smoother and slightly reduced apically ( 9 ), separated from the head 

 by a very feeble impression; antenna? piceous, the first funicular joint not 

 quite as long as the next two, the third one-half longer than wide; prothorax 

 slightly (o 71 ) or nearly a third (9) wider than long, the converging sides 

 subevenly and distinctly arcuate to the feeble apical constriction, the tubu- 

 lation with distinct scattered punctures and three-sevenths as wide as the 

 base; surface minutely, remotely punctulate; scutellum rather large and 

 transversely suboval, narrower at base than at apex; elytra fully three- 

 sevenths longer than wide, parabolic, a third wider than the prothorax and 

 two and one-half times as long, the humeri slightly prominent and broadly 

 rounded; striae not very coarse but deep, groove-like and smooth, the wide 

 intervals with sparse and confused infinitesimal punctulation; under surface 

 with rather strong loose punctuation, the abdomen feebly impressed along 

 the base medially in the male, but otherwise unmodified. Length 7.3-8.8 

 mm.; width 3.9-4.8 mm. Brazil (Rio de Janeiro). October. Three speci- 

 mens. [Baris auritarsis Germ.] auritarsis Germ. 



Form, color and sculpture nearly similar but more obtuse behind and much 

 smaller in size; spot of dense scales on the fourth interval very elongate, 

 between two and three times as long as wide; moderate sparse punctures of 

 the under surface not nude but bearing hair-like squamules, the prosternum, 

 mesosternum and mes-epimera densely squamose, and also the posterior end 

 of the met-episterna, the abdominal dense areas of the preceding wholly 

 wanting; beak nearly similar, a fourth (c 71 ) to two-fifths (9) longer than 

 the head and prothorax; antenna? slender, piceous and rather longer; pro- 

 thorax relatively smaller but otherwise nearly similar, except that the sparse 

 punctulation is more distinct; scutellum smaller, obtrapezoidal and generally 

 less transverse; elytra nearly similar throughout, but a little shorter and 

 more obtusely rounded behind; male abdomen with a larger and more oval 

 median basal impression. Length 5.8-7.9 mm.; width 3.0-3.8 mm. Brazil 

 (Chapada — forest). November. Ten specimens tritus n. sp. 



3 — Size, color and sculpture nearly as in auritarsis, but with rather shorter and 

 more obtusely rounded elytra; dense spot on the fourth interval oval, about 

 one-half longer than wide; prosternum only with moderately dense herissate 

 squamules along the sides of the depression, between the coxae and on the 

 posterior lobe; entire under surface devoid of dense areas of squamosity, 

 each of the rather coarse punctures, as also those of the femora, with a very 

 small, slender and inconspicuous squamule; tarsi densely, pallidly squamu-
