(Jlose to llir oilier ('(l<ro of the wiiiir. mikI opposite tlie roiiiided l)eii<l in tlie 

 outer l)aii(l, is a round, white spot. A minute white spot on tlie inner angle. 

 llind wings with a hxrge, black, oval discal spot; beyond an indistinct black 

 line, and beyond this a broad, white band, widening outward in the middle 

 and connected with a round, marginal, white spot; another white spot on the 

 inner angle. These markings are distinctly repeated on the under side of the 



wings.

Head rather narrower than in Odezia, but the palpi and antennae 

 the same. Fore wings inclined to be narrower than in Odezia, the costa 

 straighter; the apex is much less rounded, being subrectangular, while 

 the outer edge is a little more oblique. The hind wings are shorter, inclined 

 to be sinuous below the apex, which is shorter, much less produced than 

 in Odezia. The venation diifers in the subcostal cell being smaller, in the 

 first subcostal vein co-originating with the main vein, not being separated as 

 usual, and there is one subcostal vein less; while the last subcostal vein is 

 bent downward where it throws off the anterior discal venule. The first 

 median is widely separated from the second at its origin, in this respect differ- 

 ing much from Odezia. Male hind legs with the tibiiE much swollen, the 

 tarsi one-half as long as the tibiae. Abdomen longer and slenderer than in 

 Odezia, extending beyond the hind wing\^. Coloration : black, with large 

 white blotches, with metallic scales arranged in lines and patches. 



As seen by the characters given above, this genus differs from Odezia, 

 to which it is nearest allied, by some important features, which scrvji to con- 

 nect it with the third subfamily. 



The swollen hind tibiae and short tarsi and its peculiar style of colora- 

 tion will enal)lc one to recognize the species. Grrote remarks that "//i erota 

 Grote from Surinam belongs to this genus, and probably other species 

 hitherto referred to Erateina, the types of which latter genus are quite dis- 

 tinct from the present."
