"Then we gather, as we travel, Bits of moss and dirty gravel, And we chip off little specimens of stone; And we carry home as prizes Funny bugs of handy sizes, Just to give the day a scientific tone."
Charles Edward Carryl.
Butterfly.—Medium-sized or small butterflies, dark in color, wings marked on the under side with eye-like spots; the antennæ short, with a gradually thickened club. The eyes are naked. The costal vein of the fore wing is generally strongly swollen at the base. The subcostal vein is five-branched; the first two nervules generally emitted before the end of the cell; the third nearer the fourth than the end of the cell; the fourth and fifth nervules spring from a common stem, the fourth terminating immediately on the apex. The lower radial is frequently projected inwardly into the cell from the point where it intersects the union of the middle and lower discocellular veins. The outer margins of both wings are evenly rounded.
