THE EPHESTION BUTTERFLY. 
283 
wings, particularly of the hinder ones, scalloped but not 
tailed, the inner margin grooved so as to receive and conceal 
the abdomen below, no closed mesh in the middle of the 
wings, and no elevated spot on them in the males ; cater- 
pillars and chrysalids in form like those of the Disippe, and 
suspended only by the hindmost extremity. 
The caterpillar of the Ephestion butterfly (Nymphalis 
Ephestion of Stoll) is of a brownish color, more or less varie- 
gated with white on the sides, and with green above, and, 
like that, of the Disippe, has two long barbed brown horns on 
the second segment. I have found it on the scrub-oak 
( Quercus ilicifolia ) in June, but Mr. Abbot says it lives on 
the whortleberry-bush and the cherry-tree. 
The chrysalis is not to be distinguished from that of the 
Disippe in form and color, and the butterfly leaves it eleven 
days after the insect has changed from a caterpillar. This 
butterfly is found about the middle of June ; I have seen it 
again in September, though rarely, and the caterpillars of 
the last brood remain in the chrysalis state throughout the 
winter, and are changed to butterflies in the months of April 
and May following. This butterfly is of a blue-black color, 
finely glossed with blue on the hinder part of the wings, 
the scalloped edges of which are white, and the hind margins 
bordered with three black lines ; near the tips of the fore 
wings are two or three white spots, and just within the 
border a row of orange-colored spots ; these spots are more 
distinct on the under side of the fore wings, which are more 
or less tinged with brown, and have near the body two large 
orange-colored spots ; on the under side of the hind wings 
is a row of seven orange-colored spots inside of the hind 
border, and three more of the same color near the shoulders 
of the wings. It expands from 3 to 3$ inches. 
The Arthemis butterfly (Nymph alia Arthernis of Drury) 
(Plate I. Fig. 7) is very rare in Massachusetts, but more 
common in the hilly parts of New Hampshire. It is 
smaller than the preceding, measuring from 2J to 3 inches,
