There are two or three other species of this obscure genus, but they are rare boreal insects, of which little is as yet known.
Genus GEIROCHEILUS, Butler
Butterfly.—Medium-sized butterflies, dark in color, with light eye-like spots on the primaries and brown borders on the secondaries. The antennæ are short, with a gradually tapering club; the palpi are long, slender, compressed, well clothed with scales on the lower surface. The costa of the fore wings is strongly arched, the outer margin evenly rounded, the outer margin of the hind wings regularly scalloped. The costal vein of the primaries is somewhat thickly swollen at the base.
Early Stages.—Unknown.

(1) Geirocheilus tritonia, Edwards, Plate XVIII, Fig. 21, ♂ (Tritonia).
Butterfly.—The wings of the upper side are dark brown, with a submarginal row of white-centered ocelli below the apex of the primaries. The secondaries are marked with a submarginal band of red. On the under side the fore wings are as on the upper side. The hind wings have the submarginal band purplish-red, irrorated with whitish and dark-brown scales, on the inner edge relieved by a number of imperfectly developed ocelli, which are partially ringed about on the side of the base by pale yellow.
Early Stages.—Unknown.
Tritonia occurs in southern Arizona and northern Mexico.
