latter in the female. Prothorax subcorneal, more strongly narrowed 

 near the apex, convex, coarsely but not very densely punctate, the 

 punctures circular, about one-half as wide as the transverse scutel- 

 lum, and separated by their own diameters in some specimens, to 

 scarcely one-half that distance in others. Elytra large, fully twice 

 as long as the prothorax and nearly one-fourth wider than the latter, 

 the grooves exceedingly wide and deep, distinctly and remotely punc- 

 tate at the bottom, the intervals not at all wider than the grooves, 

 each with a single series of rather coarse very deep and distant 

 punctures, the second and third not wider, the seta? very small, 

 visible, but not in the least conspicuous. Abdomen coarsely deeply 

 and closely punctured. 



The male has the abdomen narrowly and deeply impressed nearly 

 through the length of the two basal segments, but in a small speci- 

 men from Florida this impression is very small, feeble and situated 

 near the base. Length 3.2-4.8 mm ; width 1.5-2.4 mm.

4 Baris arizonica n. sp. — Oblong, rather robust, moderately convex, 

 piceous-black, the legs and elytra slightly paler ; lustre somewhat dull from 

 the density of punctuation, the interspaces polished. Head very minutely 

 punctured, separated from the beak by an impression which is unusually 

 feeble ; beak long, not very stout, feebly arcuate, nearly as long as the pro- 

 thorax, finely but strongly, sparsely punctured, very densely so laterally 

 toward base ; antennae moderate, the club very large, stout, ovoidal, with its 

 basal joint in great part pubescent and only feebly shining toward base, basal 

 joint of the funicle shorter than the next three. Prothorax rather short, nearly 

 two-fifths wider than long, the sides parallel and broadly arcuate in basal 

 three-fourths, then rather abruptly but not angularly rounded, thence strongly 

 convergent and distinctly sinuate to the apex ; base not quite three times as 

 wide as the head, broadly and evenly Insinuate ; disk with a very short narrow 

 median impunctate spot, the punctures rather coarse, very deep and extremely 

 dense, two-fifths as wide as the scutellum and almost in mutual contact even 

 toward the middle. Scutellum short, unusually transverse, broadly, deeply 

 impressed in the middle. Elytra one-fourth longer than wide, slightly more 

 than twice as long as the prothorax, and, at the feebly tumid humeri, about 

 one-fifth wider than the latter, very broadly, obtusely rounded behind : disk 

 with coarse but rather shallow, distinctly and transversely punctate grooves, 

 the intervals wide, flat, the second and third much wider than the others, and 

 all densely, confusedly, strongly but not very coarsely punctured ; setae very 

 short, not conspicuous. Abdomen rather finely but strongly, not very densely 

 punctured. Legs short, finely, rather feebly, not densely punctate, the outer 

 line of the tibiae sinuous, the apex prominent ; tarsi pale rufous, the claws 

 rather long. Length 4.0 mm. ; vu Uli 1.95 mm.
