Genus Oarisma 



Genus OARISMA, Scudder 



Butterfly. — Closely related to the preceding genus. The an- 

 tennae 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. 



(i) Oarisma garita, Reakirt, Plate XLVII, 

 Fig. 3, 6 (Garita). 



Butterfly. — This obscure little insect is light F ig. 163.— Neura- 

 fulvous on the upper side, with the costa of tion of the genus o«- 

 the hind wing somewhat broadly marked with risma - 

 leaden gray; on the under side the fore wings are brighter ful- 

 vous, 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, 6 

 (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. 



Early Stages. — Unknown. 



Powesheik occurs in Wisconsin, and ranges thence westward 

 to Nebraska, northward to Dakota, and southward as far as 

 Colorado.
