210 THE BUTTERFLIES OF THE WEST COAST 



Expanse, .8 to i inch. Male, blue ; female, dusky-blue ; small 

 black and faint fulvous lunules at anal angle. Under side ashy- 

 blue, dusky at apices; a median band across both wings, deeply 

 indented twice on each wing, the band is somewhat after the pat- 

 tern of the band on Behri, on which account I have placed Avalona 

 next to Behri on the plate. 



It is a matter of great grief to me that the males of these figures 

 were in a wretched condition, so rubbed as to be almost valueless, 

 but I had no others. This charming new species was taken on 

 Catalina Island in 1885, as noted on the data, and I have named it 

 for the chief town on the island, near which the specimens were 

 taken. It might well have been named for Mr. Stephens, but 

 neither Mr. Stephens nor the Author favors personal names. This 

 new species was recognized as new long ago, but has been held in 

 abeyance till now that it might appear in this book.

 Behri is a lovely little butterfly, and in the Tahoe region and 

 along the Truckee River it is very abundant indeed. It is set down 

 for several of the States of the Great Basin, and as far north as 

 Oregon, so it is probable that it flies in every State of the Basin 

 north of Arizona.

 Iroides is very common in Southern California in early spring; 

 it likes to feed on the flowers of the early-flowering ceanothus. 

 This species enjoys a wider range in altitude than most butterflies, 

 as it flies on the plains, and up to an elevation of 8,000 feet ; and it 

 also reaches over the whole of the West Coast, from Arizona to 

 Vancouver Island, and perhaps still further north.
