Head with the hairs projecting, formiog a frontal tufl ; i m I j • i unusually long and 

 acute; female antenna; pectinated; wings falcate, deeplj scalloped; Bpecies 

 yellow or white Eugoiiia. 



Fore wings broad, not falcate; apex rectangular; outer edge with a slight angle, 



sometimes obsoli to Cahrodes. 



Fore wings regularly falcate; hind wings well rounded Dirpmwdc*. 



Head short, small; palpi small, scarcely extending beyond the front; wings very 



angular and falcate Metanema. 



Palpi rather long; male antennas usually pectinated; hind wings shorter, with a 



more marked angle than in Euirapela Tetrads. 



Male antennas simple ; fore wings falcate ; hind wings with a prominent angle ; the 



outer margin of both wings sometimes slightly scalloped Euirapela.

Froni broad; vertex and front continuously and thickly scaled. Palpi 



much ascending, broad, and rather stout; lip of second joint truncate, sur- 

 passing the front; third joint minute, obtuse, depressed. Antennae rather 

 narrowly pectinated to the tip. In the female, the pectinations are half as 

 long as "in the male. Thorax slender. Fore wings unusually long and 

 narrow; costa convex, especially at the base; apex acute. The angle between 

 the second and the third median venules much rounded and prominent, much 

 excavated below the apex, and below the angle in the middle of the wing; 

 more angulated in the female than in the male. Venation as in Plagodis, but 

 the costal region is wider; the costal and first two subcostal venules are 

 shorter; the second median is shorter; the third subcostal divides much 

 nearer the origin. Hind wings with the internal angle not rounded, not 

 reaching to the tip of the abdomen ; apex rounded ; middle angle of the outer 

 edge large and rounded, the outline being very sinuous. Legs long ; hind 

 tibia? slender; spurs long, and the two pairs of equal length: hind tarsi 

 three-fourths as long as the tibiae. Abdomen moderately slender; tip acute. 

 Coloration : pale, dusted with ochreous. An outer line, very much angulated 

 toward the middle angle of outer margin, with internal and subapical dark 

 patches. 



The long, narrow fore wings, acute apex, and rounded, large, middle 

 angle, antl acutely-angulated extradiscal line distinguish this genus from 

 Plagodis, to which it is nearest allied; bul it differs in the more acute apex 

 of the fore wing, the more sinuous outer edge, the angle being much rounded
