a Nine specimens. 



^ Eleven specimens. 



c The California material examined is rather meager except for the vicinity of Nicasio , 

 Marin County (the type locality). Such as it is inclines me to believe that this form 

 is restricted in its range to the humid coast strip, for the only perfectly typical examples 

 seen come from that area. Some specimens from San Diego County and one from 

 San Fernando, Lower California, seem, however, to be nearer this form than to typical 

 P. nuttallii.
