 of the basal constriction, finely transversely rngnlose and ])unctnlated : the central 

 line somewhat glabrous, bnt not quite smooth. tScutellum triangular, punctured, 

 middle of its base impuuctate, apex with transverse wrinkles. Elytra densely

Differs from S. armipes Bates iu the shape aud sculpture of the prothorax, in 

 the process of the prosternum, pubescence of \\w under surface, and in the form of 

 the abdominal segments.
