Oregon: Cornucopia, 6,200 to 7,000 ft., 1 $, July 25, 1936 (R. 
E. Reider) ; Mt. Hood, 1 $ (J. Nottingham) ; 5 miles west of 
Suttle Lake, 1 $ , July 8, 1939 (K. Gray and J. Schuh). California: 
Lassen National Park, 1 $ (C. T. Brues) ; Emigrant Gap, 1 2 (M. 
Cazier). 
Known at present from British Columbia, Washington, Oregon, 
California, Nevada, Idaho, Utah, Colorado and Nebraska. The 
normal foodplants appear to be species of Phacelia and possibly 
Besseya. Aside from Cresson’s (1864) remark that Ridings dis- 
covered Ps. zonalis in August “on a plant most likely to be of the 
genus Phacelia/’ the above flower records appear to be the first 
definite observations on the flower choice of this species. It is of 
interest that Ridings also found Ps. marginalis on the same “ Pha- 
celia ” as Ps. zonalis.
