Genus OARISMA, Scudder
Butterfly.—Closely related to the preceding genus. The antennæ are very short; the club is long, cylindrical, bluntly rounded at the apex, not curved. The palpi are stout, the apical joint very slender, elongated, and porrect. The head is broad; the body is long and slender, projecting somewhat beyond the posterior margin of the secondaries. The neuration of the wings is represented in the cut.
Early Stages.—So far as known to me the life-history of no butterfly of this genus has yet been ascertained.
[a]Fig]. 163.—Neuration of the genus Oarisma.
(1) Oarisma garita, Reakirt, Plate XLVII, Fig. 3, ♂ (Garita).
Butterfly.—This obscure little insect is light fulvous on the upper side, with the costa of the hind wing somewhat broadly marked with leaden gray; on the under side the fore wings are brighter fulvous, with the inner margin laved with dark gray. The hind wings are paler fulvous, inclining to gray, with the inner margin brighter fulvous. Expanse, .75-1.00 inch.
Early Stages.—We know little of these. The species is found in southern Colorado, ranging thence westward and southward to Arizona.
(2) Oarisma powesheik, Parker, Plate XLVII, Fig. 4, ♂ (Powesheik).
Butterfly.—This species may be distinguished from its ally garita by its larger size, the darker color of the upper side of the wings, and the red markings on the costa of the fore wings. On the under side the fore wings are black, edged on the costa and outer margin for a short distance below the apex with light fulvous. The hind wings are dusky, with the veins and nervules white, standing forth conspicuously upon the darker ground-color. Expanse, 1.00-1.25 inch.
