only accepted those species which could be demonstrated by large 

 series. The fact that nearly four hundred specimens have been 

 studied in composing the table, increases my belief that the number 

 of species at least has not been materially overestimated. 



Baris as here considered also occurs abundantly in Brazil, and 

 the species taken on the banks of the Amazon and La Plata cannot 

 be distinguished in type from our own representatives. The genus, 

 even in its restricted sense, is therefore a very large one. The 

 European species have a distinctly different fades and should be re- 

 vised from the generic point of view ; the species are surely too 

 heterogeneous to be included in a single genus. 



1 Baris in gens n. sp. — Oval, rather strongly convex, intense black 

 throughout, the integuments strongly shining. Head finely, sparsely punc- 

 tate, with a deep frontal fovea, the impression very feeble ; beak stout, evenly 

 and distinctly arcuate, coarsely strongly but not very densely punctate, three- 

 fourths as long as the prothorax, the setse long and bristling beneath ; antennae 

 rather long, the funicular joints less coarctate than usual, broad but obconical 

 near the club, the latter large, robust, the basal joint distinctly less than one- 

 half of the mass, transverse. Prothorax small, very nearly as long as wide, 

 the sides in basal two-thirds rather strongly convergent and nearly straight, 

 then broadly rounded, thence more convergent and slightly constricted to the 

 apex, which is scarcely two-fifths as wide as the base, the latter transverse, 

 the median lobe broad and strong ; disk with a very uneven and ill-defined 

 median line, the punctures very coarse and deep, abruptly perforate, one-half 

 as wide as the scutellum and generally separated by less than one-half of their 

 own diameters, each bearing a conspicuous fine cinereous seta. Scutellum 

 moderate, transverse, not strongly impressed. Elytra large, one-third longer 

 than wide, nearly two and one-half times as long as the prothorax, and, at 

 the large and longitudinally but not laterally prominent humeri, rather 

 abruptly almost one-third wider than the base of the latter ; sides parallel 

 and nearly straight in basal two-thirds, then gradually rounded to the apex, 

 which is somewhat parabolic ; disk with coarse, deep, strongly and not very 

 remotely punctured grooves ; intervals flat, one-half wider than the grooves, 

 each with a single uneven series of moderately large, deep, close-set punctures, 

 the setse moderate in length, slender, conspicuous. Abdomen rather sparsely 

 punctate, each puncture bearing a long cinereous and conspicuous setiform 

 hair, giving a strongly pruinose appearance by unaided vision. Anterior 

 coxae approximate, separated by scarcely one-fifth of their own width ; pro- 

 sternum not impressed. Length 7.3 mm. ; width 3 5 mm. 



Arizona. 



A conspicuously distinct species, easily recognizable by its large 

 size, small prothorax, ample elytra and unusually evident but slen- 

 der setae, especially pronounced on the abdomen. The type is a
