^. Size moderate; elongate, subparallel. Black; rather sparsely 

 clothed with minute, depressed subpubescence; seta? black. 



Head and rostrum much as in S. tristis; the antennal scape 

 rather longer. Prothorax (4x5 mm.) widest in front of middle; 

 subapical impression rather indefinite, median line not impressed; 

 rather closely set with small granules elongate in the middle, 

 rounded at the sides, little prominent, but less obliterated than 

 in the female. Elytra (10 x 6 mm.) elongate, subparallel, base 

 rather feebly emarginate, humeri subrectangular; seriate punc- 

 tures small, in tortuous rows deflected by the tubercles; intra- 

 strial ridges small, hardly granulate, setigerous ; interstices 

 tuberculate : sutural slightly raised, feebly granulate, more 

 strongly granulate on declivity; second with two isolated tuber- 

 cles; third with two or three conjoined, at base, and five isolated 

 tubercles, the interstice very feebly raised between the tubercles; 

 fourth with a single tubercle; fifth with ten or eleven, the basal 

 eight small, subcontinuous, from humeral angle to about middle, 

 followed by three larger tubercles, set farther apart; sixth with 

 a continuous row of thirteen, small, slightly elongate tubercles, 

 little prominent, not conical, nor outward projecting, their apices 

 directed backwards. Sides with interstices obsoletely granulate. 

 Apical ventral segment with a narrow median channel, a small 

 tubercle on either side. Anterior tarsi with second and third 

 joints asymmetrically dilatate on tlie inner side, the third the 

 larger, and spongiose beneath.

 raised ridges arranged in longitudinal wavy lines. Elytra 

 (10x6-5 mm.) with apex rather less strongly produced than in 

 S. obliteratus, bimucronate; punctures similar, tubercles small, 

 slightly elongate, not costiform at base; fifth interstice with a 

 row of small, almost minute, tubercles, moderately closely set.
