Small, delicate butterflies with elongated fore wings, having the costal vein much swollen near the base, somewhat as in the Satyrinæ. The upper discocellular is lacking in the fore wing, and the cell is feebly closed. Outer margin of the hind wing feebly crenulate; cell open; the two radials spring from a common point.
A number of species and local races have been described.
(1) Cystineura amymone Ménétries, [Plate XXXIX], ♂ (The Texas Bag-vein).
On the under side the gray markings of the upper side are replaced by yellow, and on the hind wings there is a transverse white band near the base and an incomplete row of white spots on the limbal area. Expanse 1.50 inch.
Ranges from Kansas southward through Texas into Central America.
Genus CALLICORE Hübner
(The Leopard-spots).
PL. XL
Small butterflies; the upper side of the wings dark in color marked with bands of metallic blue or silvery green, the lower side more or less brilliantly colored, the fore wings of some shade of crimson or yellow, banded near the apex, the hind wings silvery white or some pale tint, with circular bands of black enclosing round or pear-shaped black spots.
There are about thirty-five species of the genus thus far known, all of which are found south of our limits, except the one we figure.
