oiado Mr. T. L. Mead discovered the species in 1871, and since that time a 
few mdiv duals have appeared among the butterflies collected by Dr. Hayden’s 
expeditions The information given of its habits is by Mr. Mead, which I repeat 
hom the notes on G. Zephyrus , Vol. I. of this work 
“ On the 28th August (1871), on the South Park road, in the mountains, and 
about twenty miles from the Park, I found a large smooth rock exposed to the 
sun on which were several Graptas, Zephyrus , and a species numbered 3 (Hulas) 
On Ins rock, and in the immediate vicinity, I captured twenty ZephyrusSe 
of the other I had previously, on the 16th August, found both species toother 
m le vicinity of Berthoud s Pass, where fifteen of the smaller ones were°taken 
a few Zeplnjrus, on a small patch of flowers high up the mountain. These 
were the only occasions on which the small Grapta was seen. Zephyrus was 
taken abundantly throughout the State wherever collections were made.” To 
ns I add that I have received Zephyrus from various localities since 1871. The 
expeditions under Lieutenant Wheeler have taken it both in Southern Utah and 
m Arizona; and, as stated by me in Vol. I., it has been received from Nevada 
California, and even from Fort Simpson, Mackenzie’s River. 
Considering then that Zephyrus is so wide-spread a species and Ilylas so 
ocal an one, and that, the two agree neither in size, shape" color, or otWise 
except- in group characters, there would not seem to be much ground for a 
suggestion of relationship between them. Yet Mr. Scudder, in his lately pub- 
lished Synonymic List, treats the two as established dimorphic forms of one
