This remarkable species is easily distinguished by the shape of the 

 head, which is deeply incised in the centre, and has on each side of 

 the incision a bilobate prolonged process ; the sides of the head are 

 depressed and dilated, and hardly narrowed in front ; the anterior 

 angles of the prothorax are rounded as in S. cesculapius, and the 

 elytra are smooth and have simple, well-defined strige ; the outer 

 teeth of the anterior tibia? are not triangular, and are abruptly trun- 

 cate at tip.
