BY JAMES A. G. REHN. 



The specimens mentioned in the following pages are almost all con- 

 tained in the collection of the Academy, and chiefly represent collec- 

 tions made in the summer of 1902 in central Arizona, northern New 

 Mexico and central Colorado by C. F. Oslar, and in the summer of 

 1903 by C. R. Biederman, at Florence, Pinal county, Arizona. A 

 few specimens from Yuma county, Arizona, belonging to the Hebard 

 Collection, have also been studied in this connection.
