form A^. tihullus of Scudder and Burgess can be separated from 

 propertius. 



Distribution. — The original description cites California as the 

 locality. Lintner says he examined eight examples in the Scudder 

 collection, two from Mokiah Pass, Palmer Collection; one from 

 Sierra Nevada; four from California; one from the Juniper Moun- 

 tains. I do not know where Mokiah Pass is. There are Juniper 

 Mountains in Oregon, Nevada and Arizona. 



Records. — Southwestern Colorado, VII, (Oslar), (Tolman); Payson Can- 

 yon and Stockton, Utah, VII, 4, (Spalding); Corfield, Vancouver, V, 12 to 

 19; Umatilla, Oregon; California.
