 punicus (Cresson), revised status. Southern B. C, Wash., Oreg., Calif. The discussion in the 

 tribal revision of Townes and Townes (1962) indicates that there was not sufficient 

 evidence to treat punicus as a subspecies or synonym of relativus.

 relativus (Cresson). Southern Alta. s. to N. Mex., w. to s. B. C. and Calif. Host: Sesia tibialis 

 (Harris). This taxon was divided into two sympatric subspecies in the tribal revision of 

 Townes and Townes (1962); intermediate specimens which I have seen among the 

 material they studied contradict their discussion and indicate the need for placing 

 Cryptus nitschei Dalla Torre as a synonym of relativus rather than giving it species
