Not unlike S. pygmaeus, Har., and with the mesosternum of 

 similar structure. It is, however, inter alia a larger species of 

 darker colour, and having the pronotum very much more coarsely 

 punctured.

Minus elongatus ; sat parallelus ; minus convexus ; fereglaber; 

 sat nitidus ; rufus ; capite subtilissime vix crebre punctulato, 

 antice late leviter emarginato ; sutura clypeali nulla ; prothorace 

 subquadrato, quam longiori fere ut 4 ad 3 latiori, supra dupli- 

 citer (subtiliter et fortiter) subacervatim punctulato, lateribus 

 leviter arcuatis in parte antica sat late deplanatis, angulis omni- 

 bus obtusis, basi haud marginata ; scutello triangulari modice 

 elongato ; elytris fortiter crenulato-striatis, interstitiis minus 

 convexis laevibus, dente humerali sat magno ; metasterni disco 

 laevi ; mesosterno inter coxas intermedias laevi longitudinaliter 

 late obtuse convexo ; tarsorum posticorum articulo basali quam 

 tibiae latitude sublongiori.

Differs fi-om the preceding (S. mansuetus), inter alia, by its 

 mesosternum not carinate between the intermediate coxae and 

 by the lateral margins of its pronotum being very conspicuously 

 flattened in their front part.
