 Wright, Butt. W. Coast 240, pi. xxx, pp. 418, c, 419, b, c, 421, b, c, 1905. 



I follow Dr. McDunnough in making this species distinct from comma. 

 There is some difference in the male genitalia and if we restrict nevada 

 to the typical form the under surface differs as noted in the key. Arizona 

 to Northern Canada. 



8. PAMPHILA COMMA 



PampMla comma Linn., Syst. Nat. 484, 1758. 



Comma is a European species and does not occur in its typical form in 

 this country.

 17, 18, pi. xi, ff. 1, 2, 1874. 

 Arizona north to Washington, California. 



In the typical form the under surface of the secondaries is bright green 

 with the band pure white, short, rather even, and the basal marks united 

 to form a U. 



8b. race MANITOBA 

 Pamphila ma7iitoba Scud., Mem. Bost. Soc. Nat. Hist, n, 351, pi. X, ff. 8- 



11, pi. xi, ff. 7, 8, 1874.
