and it seems pretty universally distributed throughout the State. 

 There exists only one generation, and the imago is found in June.

This species is very similar to C'aUppe, but actually differs by the 

 upper side being colored in the usual way of the genus, and not 

 showing the pale lunulae and s|:ots of the disc, like A. Calippc that 

 resembles in this respect more an Eu[ toieta than a true Argynnis. 

 The lunulae are not triangular, nor are the silver spots of the inter- 

 mediate fascia egg-shaped as in Callppe. 



This species frequents several locaUtiss near the Bay of San 

 Francisco, but is not very common.

This species, although Dr. Boisduval pronounces it, in a private 

 letter directed to Mr. Lorqviin, identical with A. Cyhele, Godt. is 

 certainly a distinct species peculiar to the w-estern slope. The upper 

 side of male is like that of il GybehAQvixilQ:, and the Zicf.^ female has 

 the hind wings black, with a band of white spots in the middle, and of 

 orange ones near the margin in a similar way as in the A. Idalla male. 

 The under side of the hind wings differs most essentially as the mar- 

 ginal silver spots are always semilunar, never triangular as in A. 

 Oybele. 



This species has been discovered by our indefatigable entomolo- 

 gist, Mr. Lor(piin, m a sequestered valley near Carson City. 



A. Aylaja has been mentioned as an inhabitant of California. 

 I have not yet seen any specimen captured in this country, but 

 would not be much astonished if really this European and Siberian 

 species should extend to Arctic America, and from there following 

 the high ridges of the Pacific coast to Alpine California. Never- 

 theless it would be strange to have here a Gerontogeic spec"es when 

 all the Neogcic ones diifer ; for there is not one Atlantic Argynnis 

 met with here ; in case A. Aglaja really should prove to be a Califor
