 Alpheus is a Mexican species, and only comes into the United 

 States a little along the border. Nothing is knowji about the pre- 

 liminary stages of this butterfly ; it has but little interest for us as 

 it is scarcely belonging to our territory. 



408. Pholisora Lena. Not ever previously illustrated any- 



where.

 Lena is one of the rarest butterflies of the United States; but 

 few collections have it, and even the Government Museum at 

 Washington has it not. Yet it is not local at all, for these two 

 localities noted above are about 800 miles apart as the bird flies, 

 and doubtless Lena can be found in any of the States of the Great 

 Basin. It is not at present known to live in the West Coast 

 States proper, but may very likely be found in Nevada, and along 

 the eastern base of the Sierra Nevadas, and north into Oregon 

 and Washington, east of the Cascades. 



Genus COP.^ODES. 



The species of this genus are all of small size, all similar, one 

 to another, all golden-yellow in color. Formerly these species were 

 all listed in with the Pamphilas, but about i860 Dr. Speyer of 

 Germany separated this group from the Pamphilas, on account of 

 the size, the short antenna;, the long fore wings with acute apices, 

 and the triangular shape of hind wing, and the lack of the black 

 discal mark common to all Pamphilas. 



The sex-mark is, for the male, a short, straight, diagonal line 

 near the middle of fore wing, as shown in Figures 411, 412; in 

 the males of the other species this sex-mark is not visible. 



Our fauna contains four species of Copceodes.
