fourth, the sides thence strongly oblique and nearly- straight for 

 a short distance to the basal margin, which is tumid at the sides, 

 becoming gradualh' narrower to the middle of the dorsal surface; 

 collar short, not constricted, but separated from the pronotum 

 b}' a fine deep line. Elytra \erj large, three-fourths longer than 

 wide, fully two and one-half times as wide as the prothorax, par- 

 allel and feebl}' arcuate at the sides, the apex circularly rounded; 

 humeri very widely- exposed at base; post-scutellar impression 

 distinct, the omoplates feeble ; punctures very coarse and deep, 

 well separated, becoming finer toward apex. Abdomen densely 

 pubescent. Legs moderatel}- short, somewhat stout, the femora 

 not in the least clavate. Length 2.6-2.9 mm.; width 0.95-1.15 mm. 

 Rhode Island, New York and Iowa (Iowa City and Independ- 

 ence). The paler coloration assigned by LaFerte is probably 

 due to immaturity, as this is without much doubt the species de- 

 scribed by that author, and is one of the largest of the genus. 

 The male sexual characters are pronounced, the anterior coxae 

 being posteriorly spinose, the anterior tibite slightly' bent inward 

 toward apex and densely clothed with short stiff hairs, the fifth 

 ventral with a short, broadl}- rounded and abruptly porrect lobe 

 at apex which is finely and transversel}' impressed at its base, 

 the genital segment coriaceous and broadly sinuate, and the cop- 

 ulator}' spicule short, slender, with an elongate and feebly dilated, 

 evenly and acutel}' lanceolate tip. 



2. S. rusticilS 11. sp. — Moderately stout and convex, shining, the pronotum 

 dull, black; abdomen not paler; legs and antennse towards base slight]}' pices- 

 cent; pubescence short and fine, abirndant but rather dark in color, the longer 

 liairs of the elytra inclined and not veiy conspicuous. Head convex, much wider 

 than long, truncate and very feebly, mediallj' impressed at base; temporal 

 angles broadly rounded to the eyes, the latter ratber large and somevrhat 

 prominent, very coarsely faceted as usual; antennse not quite as long as the 

 head and prothoi-ax, somewhat slender, the joints obconical, bristling as usual 

 with long erect setae in addition to the short pubescence, club feeble, the ninth 

 joint much longer than wide and longer than the tenth which is not wider than 

 long and obconical, eleventh rather short, only slightly longer than the tenth, 

 pointed. Prothorax quite distinctly narrower than the head, almost as long 

 as wide, convex, parallel and rounded at the sides in apical half, then con- 

 vergent and sinuate to the base which is broad and margined; collar short and 

 very broad, not constiicted; punctures moderately fine, strong and very dense 

 throughout. Elytra long, fully four-fifths longer than wide, but little more 

 than twice as wide as the prothorax, parallel and arcuate at the sides, becoming 

 straight in basal fiftli; apex circularly and not very broadly rounded; humeri
