This species has the general form and characters of .S'. intricatics, 

 Fabr., but is much larger. The thorax has the punctures similar to 

 those in *S'. intricatus, but crowded together, leaving a smooth median 

 line and four irregular smooth spots near the base. The elytra are 

 dull, very densely and finely granular ; each interstice has in its 

 middle portion very minute shining dots which are placed near 

 together and give a more shining appearance to the middle of 

 the interstice. The metasternum has an impressed line for its 

 whole' length ; the punctures are distinct and not very widely 

 separated."
