Brazilian Baring 7 



at all shining, black, with pale ochreous scales loosely scattered above, finer and 

 sparse on the prothorax, except on the median line at base and indefinitely 

 denser in a broad sublateral oblique line; they are more condensed also on the 

 elytra in small subnubilous spots throughout; entire under surface and legs with 

 evenly dense scales of the same color; beak as long as the prothorax, moderate in 

 curvature and moderately slender, cylindric, finely, sparsely punctulate and 

 shining, gradually densely punctate and squamose basally; antennae at the 

 middle, piceous, the three basal funicular joints elongate, constituting together 

 three-fifths of the funicle, the first much the longest; prothorax a fifth wider 

 than long, the straight sides converging from the base, more convergent and 

 rounded beyond the middle to the subtubulate apex, which is half as wide as the 

 base, the latter evenly and distinctly bisinuate; punctures moderately coarse, 

 close, the surface opaque; scutellum well developed, transversely rounded, more 

 shining, convex, sloping anteriorly, subglabrous and finely punctate; elytra a 

 fourth wider than the prothorax and two and a third times as long, the sides 

 converging from the broad humeral swellings, more rounding apically, the apex 

 obtuse; striae fine, with moderately separated, evident punctures, the intervals 

 feebly shining, with rather strong close punctures. Length ( 9 ) 7-3 mm.; width 

 3.4 mm. Brazil (Santarem). 



The elytral apex is much more obtusely rounded than in Ambates, 

 and there is scarcely any mutual resemblance; the beak is not so 

 slender or tapering apically and the oval antennal club is much 

 less slender. 



Anambates n. gen. 



The type of this genus is a very peculiar Central American 

 species named Ambates cleroides by Mr. Champion; in general 

 appearance it is very different from any other Ambates in outline 

 and color scheme, and in the former sense recalls some of the 

 Peridinetus species. That cleroides should form the type of a 

 separate genus seems clear enough, but I regret not having an 

 example for more detailed study. 



Peridinetus Sch. 



In this well known genus the body is of oblong-suboval form, 

 with generally deep black and more or less opaque integuments and 

 marmorate vestiture of white or in part brown hair-like scales, 

 denser and broader beneath, the abdomen in great part denuded. 

 The beak is thick, feebly arcuate and almost perfectly cylindric, 

 with sparse and feeble sculpture, the first funicular joint much, the 

 second less, elongated; the femora are rather thick, with a small 

 aciculate tooth beneath, and the humeri are obtusely prominent. 

 These characters apply to the typical Peridinetus, as represented by 

 the Amazonian irroratus, and many of the Central American forms 

 placed in the genus by Mr. Champion, constitute in my opinion a 

 number of distinct genera, of which one is defined further on. The 

 South American species which happen to be in my collection at 

 present, are as follows:
