(1) Hypanartia lethe, Fabricius, Plate XXIV, Fig. 10, ♂ (Lethe).
This very handsome insect, which is quite common in tropical America, is another straggler into our fauna, being occasionally found in southern Texas. But little is known of its early life-history. Expanse, 2.00 inches.
Genus EUNICA, Hübner (The Violet-wings)
Butterfly.—The head is narrow, hairy; the eyes prominent. The antennæ are long and slender, having a greatly enlarged club marked with two grooves. The palpi have the third joint in the case of the female longer than in the case of the male. They are relatively short, thickly clothed with hairs and scales lying closely appressed to the surface. The fore wing has the costal and median vein enlarged and swollen at the base. The subcostal has five nervules, the first two of which arise before the end of the cell, the third midway between the end of the cell and the fourth nervule. The upper discocellular vein is wanting; the middle discocellular vein is bent inwardly; the lower discocellular vein is somewhat weak and joins the median vein exactly at the origin of the second median nervule. The cell of the hind wing is lightly closed.
Early Stages.—Very little is known of the early stages of this genus.
[a]Fig. 101.]—Neuration of the genus Eunica.
The butterflies are characterized by the dark-brown or black ground-color of the upper side, generally glossed with rich blue or purple. On the under side the markings are exceedingly variable and in most cases very beautiful. The genus is characteristic of the neotropical fauna, and there are over sixty species which have been described. The males are said by Bates, to whom we are indebted for most of our knowledge of these insects, to have the habit of congregating about noon and in the early afternoon in moist places by the banks of streams, returning toward nightfall to the haunts of the females. In this respect they resemble club-men, who at the same hours are generally to be found congregating where there is something to drink. Only two species are found in our region, and are confined to the hottest parts of Texas and Florida, ranging thence southward over the Antilles and Central America as far as Bolivia.

Butterfly.—This obscure little butterfly represents in Florida and Texas the great genus to which it belongs, and gives but a feeble idea of the splendid character of its congeners, among which are some exceedingly beautiful insects. Nothing is known of its life-history. It is common in the Antilles and Mexico.
