In a small collection of crane-flies belonging to the California 

 Academy of Sciences and sent to the writer for naming by

 are discussed in this paper. The types of all the new species 

 are contained in the collection of the California Academy, un- 

 less stated otherwise. I am greatly indebted to Mr. Van Duzee 

 for the privilege of examining these highly important collec- 

 tions.
