Subfamily PYRRHOPYGINÆ
(The Red-tailed Skippers).

Rather large butterflies when compared with others in the family. The antennæ terminate in a long, thick, blunt club, forming a regular curve, looking in outline like the handle of an old-fashioned walking-stick. Most of the species are red at the end of the abdomen. Confined to the New World. Only one genus and species of this family occurs within our borders.

Genus PYRRHOPYGE Hübner

PL. CXXIX

(1) Pyrrhopyge araxes Hewitson, [Plate CXXIX], Fig. 1, ♂.

Upper side correctly shown in our figure. Below the wings are prevalently yellow. Expanse 2.25-2.50 inches.

Found in Texas, Arizona, and southward.

Subfamily HESPERIINÆ
(The Hesperids).

Fore wing generally provided with a costal fold, but never marked with a sexual brand or raised patch of scales on the disk. The hind wing may be provided with a lengthy tail or simply lobed at the anal angle. Antennæ terminating in a fine point, which in some genera is bent backward at right angles to the shaft.
