SATYRUS II., III. 
varied somewhat in the shade of green, being more or less yellow, in some, yel¬ 
low prevailing on dorsum, green on the sides. They varied also in the clothing 
of the surface, some being covered with short down, others with rather long 
and appressed hairs. There was no constant character by which Nephele could be 
distinguished from Alope , but the Nepliele-Olympus differed perceptibly from the 
others. They were long and slender, and deep yellow-green with distinct side 
stripe. 
The chrysalids of Alope and Catskill Nephele were alike in color, yellow-green. 
The female chrysalids were clouded with darker green, and the edges of head 
and wing cases were cream color. The Olympus chrysalids were blue-green, 
lighter or darker, and the edgings were white. They also could be readily dis¬ 
tinguished. 
One chrysalis of Albany Alope gave a male butterfly without band, but with 
a narrow yellow nimbus about the ocelli, — an intergrade. One chrysalis of Cats¬ 
kill Nephele gave a typical female Alope, with broad yellow band, but the wings 
were darker than in southern examples. This is figured in Plate II., 3, 4. The 
Coalburgh chrysalids produced typical Alope butterflies, all of them. Two Olym¬ 
pus gave males of their own type. In 1877, a female butterfly which emerged 
from the Catskill chrysalis before spoken of, was an intergrade. 
Therefore, south of the belt of dimorphism, Alope produced Alope, but inside 
the belt, Alope produced intergrade, and Nephele produced Alope and also an in¬ 
tergrade. And Nephele-Olympus, again, outside the belt, produced its kind. 
That Nephele, north of the belt, breeds true is certain, because the intergrades 
and Alope are not found there. 
I believe Alope to have originated in the southern form Pegala Fab., which is 
characterized by its large size, its broad rufous band, and single ocellus on fore 
wing, and by six ocelli in both sexes on under hind wing; and I regret that I 
am not able to properly figure this form in connection with Alope. I cannot do 
so, because I know nothing of the preparatory stages, though by the kindness of 
the late Dr. 0. C. Sparrow and of Mr. W. H. Ashmead, of Jacksonville, Florida, 
repeated attempts to obtain the eggs have been made, but all without success. 
So far the females have refused to lay when confined with grass. Perhaps before 
this Volume closes I may yet succeed. Pegala is restricted to the vicinity of 
the Gulf of Mexico and a strip along the Atlantic coast, at least as far to the 
north as Charleston, South Carolina ; but does not appear at Indian River, Florida, 
nor, as far as observed by Mr. Mead and others, in the interior of that State. 
It seems to be mainly a coast species. I cannot learn that Pegala and Alope fly 
in the same localities or even in the same districts. There appears to be a belt 
in the cotton States, or from Georgia to Mississippi at least, in which Alope is
