uneven, consisting, on the pronotum, of extremely minute set^ which hecome 

 long slender recumbent whitish squamules in lateral fifth, and in the middle 

 before the scutellum, also with a few widely dispersed over the intermediate 

 regions ; on the elytra there is a single series of very small setae on each 

 interval, with long slender squamules very widely dispersed over the entire 

 surface ; on the under surface the squamules are denser and somewhat brist- 

 ling on the presternum especially behind, and the smaller white recumbent 

 scales are sparse throughout, but denser on the met-episterna and toward the 

 sides of the last four ventral segments. Head finely, rather sparsely punc- 

 tate, the beak moderately stout, densely punctate and sparsely squamulose 

 along the sides, evenly, distinctly arcuate and equal in length to the protho- 

 rax in the male; antennae inserted near apical two-fifths, the scape rather 

 long and strongly, gradually clavate. Prothorax three-fourths wider than 

 long, the sides feebly but distinctly convergent and nearly straight to apical 

 fourth, then strongly rounded to the apical constriction, the apex briefly 

 tubulate, rather more than one-half as wide as the base, the latter broadly, 

 feebly arcuate, the median lobe very small and feeble ; disk very unevenly, 

 moderately coarsely and deeply sculptured, the impunctate line narrow but 

 entire, well defined and somewhat elevated; sculpture longitudinally rugu- 

 lose toward the middle, closely punctate toward the sides, and more finely and 

 very sparsely punctate at lateral fourth toward base. Scutellum minute, 

 quadrate, feebly impressed. Elytra hemi-elliptical, fully one-fifth wider than 

 the prothorax and much more than twice as long ; sides feebly sinuate toward 

 apex, the latter narrowly rounded ; humeri not distinctly prominent ; disk 

 with extremely coarse, deep, abrupt and even striae, the intervals flat, equal, 

 but slightly wider than the grooves, each with a single feebly impressed line 

 of somewhat coarse close-set rounded punctures. Prosternura decidedly tumid 

 with reference to the mesosternum, narrowly, strongly impressed along the 

 middle, separating the coxae by barely one-third of their width, and, behind 

 them, declivous to the surface of the mesosternum, extending somewhat over 

 the latter. Abdomen coarsely, very deeply, rather closely punctured near the 

 base. Length 3.3 mm. ; width 1.75 mm. 



Alabama. 



The single specimen is a male, the abdomen having a rather 

 small but deep subbasal impression. This species is not at all 

 closely allied to tubulatus, and has the anterior coxae slightly less 

 narrowly separated.

The essential characters distinguishing this genus from others, 

 more closely allied to it in the present section of the tribe, are the 

 large antennal club, nearly as long as the entire funicle and resem- 

 bling that of Rhoptobaris, the small, slender, free but feebly diver-
