skirt the forest. But it is rarely to he seen in the open country, where Aphrodite 
abounds. The males appear, in the Catskills, early in June, two or three weeks 
before Aphrodite. They may he seen in company with Limenitis Arthemis and 
L. Proserpina, alighted in small clusters among the damp leaves by the road side 
or upon offal of any description. All these species are attracted by any decaying 
animal matter, and a piece of meat or a dead bird or snake has irresistible charms 
for them. Mr. Scudder, in the List of Butterflies of New England, mentions that 
Atlantis is common in the valleys about the White Mountains the last of July and 
early in August, which is a month and more later than they appear in the Cats- 
kills. The northern specimens are diminutive in size. According to Mr. Scud- 
der, Aphrodite is not found among the White Mountains. The three species, At- 
lantis, Aphrodite and Cybele occupy severally northern, middle and southern belts 
of the Atlantic slope. Of the other two large Atlantic species, Diana strictly be- 
longs to a belt still more southern than Cybele. Idalia alone is very generally 
distributed, though nowhere common, being found occasionally from Maine to 
Georgia, east of the Alleghenies. 
The larvae of Atlantis I am unacquainted with, but I am informed by Mr. 
Scudder that the late Mr. C. H. Shurtleflf found both larvae and pupae at Eastport, 
Maine. He seems to have left no memoranda respecting them but the following, 
taken from his Journal ; “ they suspend themselves by the tail to rails, boards or 
logs lying on the ground.”
