_Egg._--Flattened spheroidal, broader than high, flat at the base and rounded above.
_Caterpillar._--The head is full, the summit of either half produced upward and forward into a slender, conical horn. The body is nearly cylindrical, tapering backward, the last segment furnished with two pointed, backward projections, resembling the horns of the head.
_Chrysalis._--Relatively longer and more slender than in the preceding genus, with the thoracic prominence more acute and the head more sharply pointed.
This genus was erected to receive the single species which, until the present time, is its sole representative.
(1) =Satyrodes canthus=, Boisduval and Leconte, Plate XXV, Fig. 1, ♂; Plate III, Fig. 9, _larva_; Plate IV, Fig. 9, _chrysalis_ (The Common Grass-nymph).
_Butterfly._--It always haunts meadows and hides among the tufts of tall grasses growing in moist places. It is rather common in New England and the Northern States generally. It is found in Canada and is reported from the cool upper mountain valleys in the Carolinas. It has a weak, jerking flight, and is easily taken when found. Expanse, 1.65-1.90 inch.
_Early Stages._--These have been well described by various writers. The caterpillar feeds upon grasses.
"Oh! the bonny, bonny dell, whaur the primroses won, Luikin' oot o' their leaves like wee sons o' the sun; Whaur the wild roses hing like flickers o' flame, And fa' at the touch wi' a dainty shame; Whaur the bee swings ower the white-clovery sod, And the butterfly flits like a stray thoucht o' God."
_Butterfly._--Eyes hairy. The costal and median veins of the fore wings are much swollen at the base. The palpi are thin, compressed, thickly clothed below with long hairs. The antennæ are comparatively short, gradually thickening toward the outer extremity, and without a well-defined club. Both the fore wing and the hind wing have the outer margin evenly rounded.

_Egg._--Globular, flattened at the base, marked with irregular polygonal cells.
_Caterpillar._--The head is large, rounded, the two halves produced conically and studded with little conical papillæ. The last segment of the body is bifurcate.
