the apex; the latter distinctly narrower than the base, broadly and very 

 feebly sinuate in the middle; base broadly subtruncate; disk broadly, 

 evenly, and feebly convex, finely, not deeply and very densely punctate; 

 punctures polygonally crowded. Elytra oblong, four times as long and 

 nearly twice as wide as the pro thorax; sides nearly straight, parallel, 

 very broadly and feebly sinuate behind the humeri; the latter narrowly 

 rounded, rectangular; disk broadly, evenly convex, finely striate; striae 

 finely, rather closely punctate; intervals nearly flat, equal, except the 

 humeral interval, which is distinctly elevated nearly throughout its 

 length, the flanks beyond the elevation being nearly flat, vertical, and 

 with paler scales. Abdomen broadly convex, densely squamose; first 

 suture abruptly and rather strongly arcuate in circular segment in the 

 middle two-fifths; second segment as long as the next two together; 

 third longer than the fourth. Legs moderate; anterior and middle 

 tibiae strongly, roundly, and almost equally emarginate within near the 

 apex; tarsal claws small, connate at base. Length 7.5 mm.

The mandibular scar is rather large, terminal, circular, and 

 very distinct, not prominent within; outer margin slightly so. 

 The mentum is small, elongate, attenuate, flat, and more deeply 

 seated behind, very convex and prominent anteriorly, leaving 

 the maxillae and palpi well exposed. The mandibular notch of 

 the gen 86 is extremely broad and shallow. 



This species differs from elegans in its more depressed form 

 and much more transverse pro thorax. 



S. ferriigineus n. sp. — Form elongate; sides nearly parallel; bright 

 rufo-ferruginous throughout, scales same, whitish beneath and on the 

 elytral suture and toward tip in large marmorate masses, also feebly so 

 at the sides and narrowly along the middle of the pronotum. Head 

 and beak evenly conical; eyes rather large and prominent; front nearly 

 flat; beak slightly shorter than the head, as long as wide, feebly im- 

 pressed and foveate near the base, broadly and arcuately impressed at 

 tip; antennae long and slender; surface rather densely punctate, shining, 

 sparsely clothed with elongate squamiform hairs of various widths. 

 Protliorax nearly one-half wider than long, widest just before the 

 middle; sides thence feebly convergent and nearly straight to the base, 

 rather strongly and abruptly constricted at the apex; base and apex 

 traifsversely truncate, the former slightly the wider; disk broadly con- 

 vex, rather densely punctate; punctures oval, shallow, and variolate, 

 separated by less than their own widths; interspaces polished; scales 

 sparse, very slender, arranged transversely, slightly more robust along 

 the median line and at the sides. Elytra elongate, widest at posterior 

 third, declivous behind, acutely rounded at tip, width at the humeri, 

 which are obtusely prominent and rather narrowly rounded, one-third
