 de Turin. 



Head black obsoletely tinged with purplish ; moidli and an- 



tennK black. 

 Thorax with the disk black, but faintly tinged with viola- 

 ceous; tiiis colour is very obvious on the lateral and pos- 

 terior margins. 

 Elytra deeply striated ; the disk is less distinctly violaceous 

 than the margin, and in a particular light exhibits a sliglit 

 greenisli tinge ; l)eneath violaceous, more particularly on 

 each side ; epipletira bright violaceous. 

 This seems to be more especially an inhabitant of the 

 southern and south-western states. The second and third 

 interstitial lines from tlie suture, in my specimen, arc con 

 nected before the middle by a transverse line.
