Genus Neonympha 



Butterfly. — The upper side is immaculate gray; beneath 

 pale, with two ferruginous transverse lines. Between these 

 lines is a ferruginous line on each wing, rudely describing a circle. 

 In the circle on the fore wing are three or four eye-spots with a 

 blue pupil and a yellow iris; in the circle on the hind wing are 

 six eye-spots which are oblong and have the pupil oval. Ex- 

 panse, 1.25 inch. 



Early Stages. — These have been fully described, and are not 

 unlike those of other species of the genus. The caterpillar feeds 

 on grasses. 



The insect ranges from New Jersey to the Gulf of Mexico as 

 far west as Texas.

 Plate III, Figs. 3, 6, 10, 13, 14, larva; Plate IV, Fig. 28, chrysa- 

 lis (The Little Wood-satyr). 



Butterfly.— Easily distinguished from other species in our 

 fauna by the presence of two more or less perfectly developed 

 ocelli on the upper side of the fore wing and also of the hind 

 wing. Expanse, 1.75 inch. 



Early Stages. — This is a rather common butterfly, the larval 

 stages of which have been fully described by various authors. 

 The egg is even taller in proportion to its breadth than that of 

 N. gemma, which it otherwise closely resembles in outline and 

 sculpturing. The caterpillar is pale brown, conformed in gen- 

 eral form to that of other species of the genus, but somewhat 

 stouter. It feeds on grasses. The chrysalis is pale brown, 

 mottled with darker brown. 



The insect ranges through Canada and the United States to 

 Nebraska, Kansas, and Texas. 



(5) Neonympha mitchelli, French, Plate XXV, Fig. 6, $, 

 under side (Mitchell's Satyr). 



Butterfly.— Easily distinguished from the other species of the 

 genus by the eye-spots on the under side of the wings, four on 

 each of the primaries and six on each of the secondaries, arranged 

 in a straight series on the outer third, well removed from the 

 margin. These spots are black, ringed about with yellow and 

 pupiled with blue. 



Early Stages. — Unknown. 



The species is local, and thus far is recorded only from 

 northern New Jersey, near Lake Hopatcong, and the State of
