THE CANADIAN ENTOMOLOGIST. 19 



These are: — S. agilis, Scop.; vS. setulosus, Ferrari; S. medius, Mis. 

 Rey, and S. iieglectus, H. S. 



In the other genus, Cafitacader, A: & S., two species only are known 

 — C. quadricornis,2i\\d C. Staudingeri, Baer., also from south Europe. 



Now, the detection of representatives of these genera in North America 

 is especially gratifying to me, and below will be found full generic and 

 specific descriptions.
