186 THE BUTTERFLIES OF THE WEST COAST 



The appearance of Wheeleri is similar to the preceding, Gabbi, 

 and might easily be mistaken for that species ; it has more of a 

 white-and-black appearance, and is not so red as Gabbi, and the 

 apical ocelli are supposed to be all of them twinned, or to have 

 an echo on the lower side ; and on under side of fore wing both the 

 ocelli are twinned, the echoes being between the two large ocelli. 

 But probably not enough of them have ever been taken to make 

 sure of these things, as the Satyrids are subject to variations 

 among themselves, on these minor points. 



Wheeleri was illustrated by Edwards, in Butt. N. A., in 1877 ; 

 by Mead, in Wheeler's Expedition Report, in 1875 ; and by 

 Strecker, in Lep., pi. 4, 1873, and pi. 8, 1874, under the name of 

 Hoffmanni.

 Nephele inhabits the New England and Middle States, and is 

 said to fly as far west as the Sierra Nevadas and the Cascade 

 Range of mountains in Oregon and Washington ; or, as one 

 writer says, to the Pacific Ocean. I have never taken it in the 

 western parts of the Pacific States, and do not believe that it flies 

 so far west ; moreover, I think it a very rare thing west of the 

 Rocky Mountains. 



The number of ocelli on underside of hind wings varies from 

 one to six ; this figure, b, shows as many ocelli as are ever present.

 Boopis is one of the Ariane group, and is quite widely distribu- 

 ted over the northern parts of the States of the West Coast, on the 

 mountains of moderate height, as well as near the sea-coast. Like 

 so many Satyrids, it is variable, especially as to the ocelli. The 

 chief characteristic or key is the wide indefinite yellow halo around 

 the ocelli on fore wing.
