 densely and somewhat coarsely jjunctured; scutellum conically produced, the apex termin.ating

Superficially this form closely resembles the type of the genus (S. volusus. Walker) 

 but besides other points of difference it is easily separable by tlie sculpture of the thorax 

 which in volxisus has the humeral angles of the thorax conspiiunusly smooth and shining, not 

 coarsely punctured and no carina; on the median segment.
