66 BUTTERFLIES OF MAINE. 
Sub-Family—SATY RIN. 
33. NEONYMPHA EURYTRIS, F. 
Ne-o-nym’-pha eu'-ry-tris. 
Expanse of wings, from one inch and a half to two inches. 
Upper side of wings, dark wood-brown, with a slightly 
paler band across the ends, on which rest two eye-spots on 
each wing. ‘These spots are black, with yellow rings, and a 
double metallic spot in the center. A triple line runs along 
the outer margin of the wings. 
Under side of wings, lighter with a triple line along the 
outer margins and two wavy lines across the wings, one be- 
fore, the other beyond the middle. The eye-spots of the 
upper side are repeated with two double silvery spots 
between. There are four eye-spots on the upper side of the 
hind wings, the upper and lower being the smallest. 
This species has never been taken in this vicinity, but 
occurs in the western part of the State. The larva feeds on 
grass and hibernates in the winter, after which it completes 
its development, giving rise to the butterfly in June or July, 
thus having but one generation in a year. The eggs are 
pale yellowish green, nearly globular, flattened at the place 
of attachment, the surface covered by a fine net-work of 
slightly raised lines. They are deposited singly on the blades 
of grass, and hatch in about ten days. The young larva is 
.08 of an inch long, cylindrical, thickest in the middle, taper- 
ing each way, the last segment ending in two short tails ; 
body covered with fine white hairs, slightly re-curved ; color 
pinkish white, marked lengthwise by seven crimson lines, one 
of which is along the middle of the back and three on each 
side.
