near the sea; but generally met with in the woodland and mountain 
regions in the interior. The specimens collected were destroyed, and the 
only one brought home was sent to Mr. Strecker, who writes as follows :— 
“TI have strong doubt about the genuineness of this species. I compared 
the female you sent me with five females of Pe/idne (from above Rupert’s 
House, B. A., and Labrador), and the only difference I can detect is th 
color of the upper surface of the wings. The one you sent me is yellow, 
while my examples of Pe/idne are white, which is no distinction at all in 
the Coliades, as most of them are blessed with two kinds of females, one 
the color of the *male, and the other albino.” 
ARGYNNIS CHARICLEA Æsp.—One of the earliest and most common 
butterflies in Labrador. In my opinion, distinct from Boisduvali, which 
appears at least a month later in the north. I took fresh specimens of the 
latter at Mingan, six years ago, on the 22nd of July, when charic/ea had 
terminated its season. Mr. Morrison pronounces the above as a variety 
of Boisduvalii, stating that he possesses specimens from the Alps. 
ARGYNNIS ATLANTIS Zdws.—When on my way home, about the end 
of July, I took a specimen of the above at Sawbill River. It agrees in 
every particular with specimens taken by my friend, Mr. Strecker, in 
Luzerne County, Pa. He states that the Pennsylvania specimens are 
darker and more reddish than those in his collection from Lake 
Superior. 
PHYCORIDES THAROS Cram.—I took a few specimens of this butterfly 
at Sawbill River, Labrador, which I regarded as a Æelifaea, but, being in 
doubt regarding the species, I sent an equal share to those who were 
entitled tothem. Mr. Morrison named it as above, stating that it occurs 
from Labrador to Texas, and the Atlantic to the Rocky Mountains. The 
* T huve notic-d this curious connection with Pieris Rapæ, which have extremely 
yellow males, occurring here in the fall. Onmy return from the North, I captur d near 
this city, last September, a yellow mile in coitu with a white female. I sent the former 
to Mr. Morrison, of Boston, who states that is is “the var. Novanglia Scudd., and that 
it is not uncommon in the spring around Boston.” I am of opinion that white and sul- 
phur yell :w varieties of rapae may be found constantly wherever they occur. The food 
plants of rapae are cabbaze, mignonette, nasturtium, and various cruciferae, therefore 
it may be that the American specimens exhibited by Mr. Scudder in Europe, were what 
the late Mr. Walsh termed phytophagic. Tere is no doubt, in my mind, that the food of 
caterpill rs produces the varieties which lead to so mune confusi n in the determination 
of butterflies. My friend, Mr. F. B. Caulfield, of this city, informs me that he has 
reared caterpillars of rapae, found on mignonette, which produced imagoes of a deep 
sulphur yellow.
