by a fine line; disk minutely, very denselj' punctate, and densely clothed with 

 minute closely decumbent pubescence. EU/tra strongly, transversely im- 

 pressed near the base, distinctly dilated behind, rather more than twice as 

 -wide as the prothorax, not quite twice as long as wide, and not longer than the 

 head and prothorax together, dull, densely, extremely minutely and almost 

 invisibly punctate, densely clothed with very minute, closely decumbent, dark 

 gray and inconspicuous pubescence, coarser and Ijrown in a transverse fascia at 

 basal two-fifths, inmiediately before which there is a transverse fascia of 

 longer, less decumbent, coarser silvery pubescence; apex broadly, obtusely 

 rounded. Under surface and legs minutely and densely pube.scent, the latter 

 relatively rather long. Length 2.3 mm.; width 0.55 mm. 



Florida (Haw Creek). Hubbard and Schwarz. 



The ei'ect, widely dispersed setaj of the upper surface are short 

 throughout, but those of the bristling fringe along the lateral 

 edges of the mesosternum, visible from above, are verj'^ long and 

 conspicuous. Sexual characters are not apparent in the single 

 specimen before me.

The very small polished and sparsely* setose species, for which 

 this genus was erected by LeConte (Ann. Ijyc. Nat. Hist., 

 N. y., Y, p. l'^2), certainly cannot be associated with the large 

 forms of totally different habitus, which include the tj'pes of 

 Formicomus Laf., nor can the}' be placed with Anthicus, as sub- 

 sequently- suggested b}- LeConte (Proc. Acad. Nat. Sci., Phila., 

 1852, p. 94), because of the remarkable structure of the meso- 

 sternum. The onl}- course left, therefore, is to regard them as 

 constituting a distinct genus. 



The anterior coxal cavities are closed behind b}^ an extension 

 of their corneous floor, and, in scitula, the median line of the floor 

 is produced behind in a slender cusp-point wiiich, however, does 

 not project posteriorly further than the lateral lobes, from each of 

 which it is separated by a small deep rounded emargination. The 

 fourth palpal joint is only moderately large, triangular and ob- 

 liquely truncate. 



The species are confined to the extreme south of the United 

 States, from the Atlantic to the Pacific, extending also into 

 Mexico, but the approximate southern limits of range are not at 

 present determinable. 



Our four species may be known as follows : —
