SUPPLEMENTARY NOTES. 
repeatedly bred from the egg, and the preparatory stages were described by me 
in “ Psyche,” vol. iii., p. 123, 1880. 
Satyrus Pegala, Fab. — Under S. Alope I had occasion to speak of Perjala, 
a species mostly confined to the southern part of the Gulf States. “ 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, S. C. I cannot learn that Pegala 
and Alope fly in the same localities or even in the same districts.” Within the 
last two years, Mr. E. M. Aaron has discovered a few examples of Pegala in 
southern New Jersey, and I have seen some of them which were taken by him. 
They are like examples from Georgia, except that they are smaller. Mr. Aaron 
writes me that at the same time he took many Alope, but saw no evidence 
of any intergrading between the two species. Each was persistent to its own 
type. There is no reason as yet to doubt that Pegala and Alope are distinct 
species. 
Chionobas Californica. — The figures were made from a pair, two of four 
collected by Mr. Lorquin, and in Dr. Boisduval’s collection. Since the Plate was 
published Mr. Morrison has found the species abundant on Mt. Hood, Oregon 
(1880). A series shows it to be constantly distinct from Iduna, which has 
also of recent years been taken in considerable numbers by Messrs. Baron and 
Behrens, in northern California. 
Libythea Bachmani. — The complete larval history was not known when 
the Plate issued, in 1874. I give it as follows : — 
Young Larya. — Length just from egg, .04 inch; cylindrical; the segments 
a little rounded, and four times creased transversely ; covered with a fine short 
down; color green, semi-translucent; head twice as broad as 2 ; obovoid, a little 
depressed at suture, the vertices rounded; sparsely pilose ; color yellow-brown. 
To first moult about 2 days, in July, 
After first moult: Length at 12 hours, .08 and .09 inch; color brownish-green, 
the segments curved ; head a little broader than 2, shape as before; coloi yel¬ 
low-green. To next moult 2 days. 
After second moult: Length at 12 hours, .12 inch ; same shape; upper side 
dark green; a faint shade of yellow over and along basal ridge, lathei macular; 
under side, legs, and feet lighter green; the segments much specked with faint 
white on the ridges caused by the creases; on 3, high up, a black dot on eithei 
side ; head as before ; color light green. To next moult 2 days. 
After third moult: Length at 12 hours, .26 to .28 inch; color dull gieen, yel 
lowish along and over basal ridge; specked with pale white, or yellow-white, as 
before ; the black dots as before ; head green. To next moult about 2 days. 
After fourth moult: Length at 12 hours, .4 inch. Four days latei the laiva 
reached maturity.
