NORTH AMKIIICAN COLEOrfERA. 129 



Easily recognized by its bright fulvous color; resembles, and is 

 closely related to jiavicans, which it I'esenibles in form, and from 

 which it is distinguished by the second joint of funicle being dis- 

 tinctly longer than the third, and the bright fulvous scales. 



S. fliEvicaiiM Lee— Oblong-siiboval, dark piceoiis, clothed above with rather 

 small, ochreous, elongate oval scales, a little larger and placed nearly transversely 

 on the protliorax, not at all crowded, without a trace of variation in color on 

 the elytra, scales on the underside very small, pale yellowish. Beak (male) 

 rather robust, slightly curved, of nearly equal thickness, scarcely longer than 

 the prothorax, subopaque, thinly scaly, except at the base, wliere the scales con- 

 dense to form two prominent basal tufts; scrobes oblique. Antennae stout, in- 

 serted fully two-fifths from the apex, second joint of funicle not longer than 

 the third, outer joints wider, club stout, basal joint subglabrous. Front scaly, 

 punctate. Piothorax a trifle wider than long, distinctly narrowed in front, very 

 broadly rounded on the sides and scarcely constricted at the apex, very little 

 wider at middle than at the base, rather densely and apparently coarsely punc- 

 tured, punctures nearly entirely concealed by the scales; scutel rounded, glab- 

 rous. Elytra scarcely one-third wider at the base than the prothorax, nearly 

 twice as long than wide, side subparallel for one-half their length, then broadly 

 rounded to tip, strise rather coarse, not at all concealed by the scales, punctures 

 fine, remote and rather indistinct, interstitial setje short, suberect. distinct; 

 prosternnm rather deeply emarginate, postocular lobes broad, not prominent. 

 Thighs strongly clavate, tibite slender, widened at apex, especially the posterior 

 ones, tarsi slender, third joint broadly and deeply bilobed ; claws smaller than 

 in the preceding species. Length 2.75 mm. ; 0.1 1 inch. 



Hab. — Arizona, Texas (LeConte). 



A single male specimen in Dr. Horn's collection is before me ; 

 closely related to fidvus. Casey's description does not api)ly to the 

 species under consideration, and is at variance in every important 

 particular with the description given by Dr. LeConte. 



SMKKOXYX Scb. 



As here defined, the genus presents the following characters : 

 Beak variable, antennal club small, sometimes moderate in size, first 

 joint forming less than one-half of its mass. Head rounded, mod- 

 erately large, front S(juamous in most of the species, separated from 

 the beak by a well-defined constrietion. Eyes transversely oval, 

 narrowly separated underneath. Prothorax variable, narrowed an- 

 teriorly and constricted at the apex in most of the species, postocular 

 lobes distinct in most, obsolete in a few of the species ; scutel distinct, 

 generally quite small. All the tibiae unguiculate at the apex. Tarsal 

 claws very small or moderate in size, connate to a variable extent. 



Represented by a large number of species, differing greatly in ap- 

 pearance as well as structurally. The type of the genus is S. reichel
