 OKANAGANA. 



By Wm. T. Davis, 

 New Brighton,- Staten Island, N. Y. 



Through the courtesy of Mr. Edward P. Van Duzee I am enabled 

 to describe a new species of Okanagana from Oregon. The fifteen 

 specimens examined came originally from the Oregon Agricultural 

 College and Experiment Station, Corvallis, Oregon.
