Brazilian Barin/e 5 



referred to this genus, which differs radically from Ambates in the 

 structure and sculpture of the beak and position of the antennae. 

 The following is related to solani, but is smaller in size: 



Batames divisus n. sp. — Suboblong, opaque, piceous, the legs not definitely 

 paler; pubescence very short, rather sparse, not intermixed with paler scales, 

 the externally arcuate and subsutural, velvety-black areas — limited internally by 

 the first stria — nearly half as long as the elytra and situated at equal distance 

 from base and apex; beak very stout, strongly arcuate dorsally but feebly sinuate 

 below, the antennae concolorous, the two basal funicular joints elongate, subequal, 

 the first much the stouter; prothorax nearly a third wider than long, the sides 

 parallel and straight, oblique in less than apical half; punctures rather strong 

 and dense; basal lobe moderately prominent; scutellum moderate, transverse, 

 more shining; elytra nearly one-half wider and two and one-half times as long 

 as the prothorax, the humeri obtusely prominent, the subapical umbones strong; 

 sides more rapidly converging apically; striae rather fine, indistinctly punctate, 

 the intervals flat, finely, densely punctate; under surface finely, sparsely, 

 linearly squamulose, the scales dense, large and ochreous on the prosternum. 

 Length (c?) 4.0 mm.; width 1.7 mm. Panama (Bugaba). 



Related closely to solani, but smaller and narrower, the prothorax 

 without median pale line, and the very faint lateral lines do not 

 extend upon the head as related of solani. The elytral area covered 

 by black scales is deep velvety-opaque and not "smoother and 

 shining." The length of solani is 4.5-6 mm., and the minimum 

 width given as 2 mm. It seems to be widely diffused, but several 

 other distinct species are probably included at present, besides 

 divisus and the one noted by the author as a variety. 



Macrambates n. gen. 



The type of this genus is Ambates melanops Chmp., from Bugaba, 

 Panama. A male and female transmitted by the author do not 

 agree very well with the description, being more slender, with 

 sparser and less conspicuous vestiture and virtually unconstricted 

 thoracic apex; the prothorax, being barely visibly wider than long, 

 could scarcely be termed " transverse." The antennae are, however, 

 inserted far beyond the middle of the beak in both sexes and partic- 

 ularly in the male. 



Ambates Sch. 



The following species is doubtless closely related to the generic 

 type, named pictus by Gyllenhal, but has a shorter prothorax, this 

 being described as longer than wide in pictus; there is also some 

 difference in elytral ornamentation, the apex having an oblique 

 line of ochreous scales behind the oblique posterior part of the 

 ambient line: 



Ambates circumcinctus n. sp.- — Oblong-suboval, rather convex, subopaque, 

 black, the close discal scales above rusty-black; the prothorax above has a fine
