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 njargins 

 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 (Nymphakis Arthemis 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 2f to 3 inches,
