1. S. pillictiger n. sp. (Fauvel MS.). — Form moderately slender. 

 Pubescence rather sparse, very short, semi-erect, setiform, and cinereous. 

 Head robust, notably less than twice as wide as long ; interocular surface 

 two and one-half times as wide as the eye, moderately excavated, finely and 

 rather closely punctate ; longitudinal elevation broad and distinct, bordered 

 by two sharply marked sulcations ; ocular lines meeting at about two lengths 

 in advance ; antennae slender, much lunger than width of head, basal joint 

 black, remainder dark piceous, club moderate ; third joint twice as long as 

 the fourth and slightly longer than the fourth and fifth together, sixth and 

 seventh equal in length, eighth joint thicker than the sixth, joints of club 

 uniformly increasing in length, last two equal in thickness, last joint acumi- 

 nate at tip ; first joint of maxillary palpi testaceous, second and third piceous- 

 black. Prothorax somewhat elongate, widest at a distance behind the ante- 

 rior margin equal to one-sixth the length, sides thence parallel and very 

 slightly arcuate for a distance equal to one-half the length, and rather 

 rapidly convergent and sinuate for the remaining distance posteriorly ; width 

 equal to three-fourths that of head, about one-fifth narrower than long ; 

 anterior margin slightly longer and more arcuate than the posterior ; surface 

 broadly and feebly impressed on the flanks at the middle, finely, extremely 

 closely and somewhat regularly punctured; canaliculation narrow and very 

 shallow, commencing slightly before the middle and extending posteriorly 

 one-third the total length. Elytra at base as wide as the head, sides just 

 perceptibly divergent posteriorly, much longer than wide ; together broadly 

 and very strongly emarginate posteriorly with the lateral emarginations very 

 feeble ; suture nearly one-fourth as long again as the pronotum ; surface 

 convex, rather finely, evenly, and extremely closely punctate, interspaces 

 acute ; on each elytron there is a very small, oblong, orange-yellow spot just 

 behind the middle, and notably nearer the exterior than the interior edge. 

 Abdominal segments decreasing gradually and uniformly in width, first 

 nearly as wide as the contiguous elytra, border prominent; surface convex, 

 closely, feebly, and coarsely punctulate ; transverse carinae not cuspid. 

 Legs long and very slender, black throughout ; first joint of posterior tarsi 

 twice as long as the second, not equal to the next three together, joints very 

 slender and cylindrical. Under surface of abdomen polished and extremely 

 finely punctulate.
