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. Expanse, 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.

(4) Neonympha eurytus, Fabricius, Plate XXV, Fig. 4, 8; Plate III, Figs. 3, 6, 10, 13, 14, larva; Plate IV, Fig. 28, chrysalis (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 general 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, 3, 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

Michigan. No doubt it occurs elsewhere, but has been overlooked by collectors.

(6) Neonympha sosybius, Fabricius, Plate XXV, Fig. 5, ô, under side (The Carolinian Satyr).

Butterfly. The upper surface is immaculate dark mousegray. On the under side the wings are paler, with three transverse undulatory lines, one defining the basal, the other the median area, and one just within the margin. Between the last two are rows of ocelli. The spots in these rows are obscure, except the first on the primaries and the second and last two on the secondaries, which are black, ringed about with yellow and pupiled with blue.

The female is like the male, but a trifle larger.

Early Stages. These have been described by Edwards, French, and Scudder, and do not differ strikingly from those of other species.

The species ranges from the latitude of New Jersey southward, throughout the southern half of the Mississippi Valley to Mexico and Central America.

(7) Neonympha rubricata, Edwards, Plate XXV, Fig. 3, ô (The Red Satyr).

Butterfly. Easily distinguished by its much redder color from all its congeners, among which it has its closest ally in N. eurytus. It has an eye-spot near the apex of the fore wing, and one near the anal angle of the hind wing. The basal area of the primaries beneath is bright reddish; the secondaries on this side are gray, crossed by two transverse lines as in the preceding species, and a double submarginal line. On the fore wings the double submarginal line is repeated, and in addition there is another line which runs upward from just before the inner angle to the costa, at about one third of its length from the apex. The eye-spots of the upper side reappear below, and in addition there is another near the outer angle of the secondaries, and a few silvery well-defined ocelli between the two on the secondaries. Early Stages.- Unknown.

The Red Satyr is found in Texas, Arizona, Mexico, and Central America.
