Undoubtedly congeneric with the typical form S. 
cyanipenne, Serv. The species somewhat resembles in 
general form and range of colours Callidiuyn {Phyma- 
todes) variahile, but is broader. It seems to be closely 
allied to Sph. rusticum (Burmeister) , from Uruguay; but 
I cannot feel sure of the identity of the two from the 
description.
