 ALEXANDER D. MACGILLIVRAY 



The following six species of saw-flies were collected on

 The material was received for identification from Mr. E. P. 

 Van Duzee, Curator, Department of Entomology of the 

 California Academy of Sciences, and the types of the new 

 species have been deposited in that institution.
