Hab. — Victoria: Portsea (Dr. J. H. L. Cnmpston). 



This species is more nearly related to C. marmoratiis (Skuse) than to C. molestus (Skuse), the only 

 two known southern forms with spotted wings. It may, however, be distinguished by the spots being 

 more numerous and irregular in size while they appear to be more regular in size in C. marmoratiis and 

 C. molestus. It also differs in thoracic ornamentation.
