Its nearest allied species is C. sidcatulum White, which has likewise the head 

 and protliorax igneous, and the elytra bluish black with tiie suture green ; but C. 

 sulcatulain is less robust than C. imitator, the lateral teeth of the prothorax are 

 shorter and the structure of the latter is different.
