This new genus is founded on Callidium zealandicum, Blanch., an insect 

 having no near affinity to Callidium^ but which Lacordaire was inclined to 

 place in Callidiopsis, and White included in (Emona. It diffei*s in essential 

 characters from all these groups, and seems most nearly allied to the American 

 genus Elaphidion.

Rusty brown in colour, with paler pubescence ; the smooth streaks on the 

 thorax consist of a dorsal line and two discoidal ones on each side, the inner 

 of which is connected with a rounded tubercle, and the outer short and 

 sometimes obsolete ; the elytra are rugose-punctate throughout.
