the outer edge. The venation is remarkably differeni from thai of Corycia 

 and allied genera. The costal area is remarkably broad, the costal vein very 

 straight; thefirsl subcostal venule is straighl and about two-thirds as long as 

 the costal; the second and third subcostals are remarkably short and originate 



\er\ near the apex, the second subcostal arises hall-way between the apex 

 and the origin of the fifth subcostal venule; the anterior discal venule is short 

 and straighl as usual; the posterior discal is remarkably long and very oblique, 

 earning the origin of the first median and independent venules out opposite 

 to that of the fifth subcostal; the independent vein co-originates with the first 

 median. Hind legs with slight, not swollen, tibiae; tarsi slender, and nearly 

 as long as the tibiae. Abdomen t hick ; tip suddenly conical. Coloration snow- 

 white, with two series of pale, faint, dusky spots. 



This remarkable genus may be recognized by the full, arched costa of 

 the fore wings, the simple antennae, the slight palpi, and the remarkable 

 venation, the independent vein arising next to the first median. This abnor- 

 mal character throws light on the history of this vein, and shows that it was 

 originally a branch of the median vein. In other characters drawn from the 

 venation, it approaches Deilinia rather than Corycia.

3<?. — Uniformly white. Head white; palpi dark. Fore and middle legs 

 blackish-brown beneath. Fore wings with two rows of indistinct smoky 

 spots on the venules; the inner regularly curved, the outer broadly sinuate, 

 situated on the outer quarter of the wing, the inner crossing at the origin of 

 the fourth median venule. Secondaries the same; beneath, the costa of fore 

 wings slightly tinged with brownish at base. Two discal dots present on 

 each wing; a dot at the origin of each discal venule. 



Length of body, 0.30; length of fore wings, 0.50; expanse of wings,
