robust ; posterior tarsi nearly three-fourths as long as the tibia;, somewhat 

 robust, the basal joint one-half as long as the second. Length 2.;5 mm. 



North Carolina ; Texas ; Arizona. 



Tiiis species resembles apicalis in sculpture, but is decidedly 

 moi-e robust, paler in color, with the apical pale area less defined 

 than in the mature specimens of apicalis; the sternal characters are 

 nearly as in that species, but the antennal club is more robust 

 toward apex, and the tibial spurs are also more robust. 



The type is a male and exhibits the strongest sexual characters 

 which I have observed in the genus. The third segment of the 

 abdomen has, just before the apex, a short broad porrected tooth in 

 the middle, which does not extend beyond the apical margin, and 

 bears along its apex seven or eight very short robust porrected 

 spinules. The fourth segment has a feeble median impression, and 

 the fifth has the usual very feebly defined transverse impression 

 near the apex. 



S. pallidUS n. sp. — Evenly elliptical, about two-fifths longer than wide, 

 polished, pale flavo-testaceous throughout. Head very finely, feebly punc- 

 tate ; antennae slender, club slender, compact, third joint scarcely as long as 

 the next two combined, fourth shorter than the fifth. Prothorax very distinctly 

 more than twice as wide as long ; punctuation obsolete ; basal lobe extremely 

 feeble, the bead obsolete. Scutellum ogival, wider than long. Elytra nearly 

 as in apicalis, except that they are less attenuate and rather more broadly 

 rounded behind, uniform testaceous in color, and with a very feeble obsolete 

 reticulation near the apex. Abdomen very feebly reticulate, the reticulation 

 very fine, dense and strong toward the base of the basal segment. Legs 

 moderate or rather short ; spurs of posterior tibiae very small, slender ; poste- 

 rior tarsi three-fourths as long as the tibiae ; basal joint two-thirds as long as 

 the second and more robust ; first and second sparsely, finely spinose beneath ; 

 third slightly dilated, bilobed, with a tuft of whitish hair beneath. Length 

 1.9 mm. 



Rhode Island. 



The sternal characters are nearly as in apicalis, from which this 

 species differs in its smaller size, pale uniform color, relatively 

 slightly longer basal joint of the hind tarsi, and finer, stronger and 

 denser reticulation along the base of the abdomen. The reticulation 

 at the apices of the elytra, although very feeble, is more distinct 

 than in apicalis, where it is all but totally obsolete ; in jjallidus it 

 is distinctly traceable over most of the apical half of the elytra, 

 being especially noticeable in lines accompanying the series of 

 punctures.
