NEW GENERA AND SPECIES OF NORTH AMERI- 

 CAN CERAMBYCIDiE. 



By H. C. Fall, 

 Pasadina, Cal. 



During the past few years isolated descriptions of a number of new 

 species of longicorns have been drawn up by the writer, and it is 

 thought best to bring these together in a short paper at this time. 



It is believed that the species are all sufficiently distinct to warrant 

 this procedure.
