"I saw him run after a gilded butterfly; and when he caught it, he let it go again; and after it again; and over and over he comes, and up again; catched it again." SHAKESPEARE, _Coriolanus_. _Butterfly._--The butterflies are medium sized, varying much in the form of wing, in some species greatly resembling other _Pierinæ_ in outline, but more frequently resembling the Ithomiid and Heliconiid butterflies, which they mimic. Some of them represent transitional forms between the type commonly represented in the genus _Pieris_ and the forms found in the two above-mentioned protected groups. The eyes are not prominent. The palpi are quite small. The basal joint is long, the middle joint oval, and the third joint small, oval, or slightly club-shaped. The antennæ are long, thin, terminating in a gradually enlarged spindle-shaped club; the fore wings being sometimes oval, more frequently elongated, twice, or even three times, as long as broad, especially in the male sex; the apex pointed, falcate, or rounded. The cell is long and narrow. The first subcostal vein varies as to location, rising either before or after the end of the cell, and, in numerous cases, coalescing with the costal vein, as is shown in the cut. _Early Stages._--Of the early stages of these interesting insects we have no satisfactory knowledge. [Illustration FIG. 138.--Neuration of the genus _Dismorphia_.] The species of the genus belong exclusively to the tropical regions of the New World. There are about a hundred species which have already been named and described, and undoubtedly there are many more which remain to be discovered. These insects can always be distinguished from the protected genera which they mimic by the possession of six well-developed ambulatory feet in both sexes, the protected genera being possessed of only four feet adapted to walking. (1) =Dismorphia melite=, Linnæus, Plate XXXVII, Fig. 17, ♂; Fig. 18, ♀ (The Mime). _Butterfly._--The figures in the plate make a description of the upper side unnecessary. On the under side the wings of the male are shining white, except the costa, which is evenly dull ochreous from the base to the apex. The hind wings are ochreous, mottled with pale brown. The female, on the under side, has the fore wings very pale yellow, with the black spots of the upper side reproduced; the hind wings are deeper yellow, mottled with pale-brown spots and crossed by a moderately broad transverse pale-brown band of the same color. _Early Stages._--Unknown. The species is credited to our fauna on the authority of Reakirt. It is abundant in Mexico. It mimics certain forms of _Ithomiinæ_. Genus NEOPHASIA, Behr "It was an hour of universal joy. The lark was up and at the gate of heaven, Singing, as sure to enter when he came; The butterfly was basking in my path, His radiant wings unfolded." ROGERS.
