ROMOSA.—-EUPALIA., 217 
1. Romosa invaria. 
Romosa invaria, Walk. Cat. v. p. 11151. 
Hab. Honpuras (Dyson 4, in mus. B.). 
The type in the British Museum is the only specimen I have seen. 
VIPSANIA, n. g. 
Male. Body short and stout ; proboscis not visible; palpi very long, projecting straight out from the head, the 
third joint small and club-shaped ; antenne slender, simple, and about half the length of the wings; 
thorax flat and rather broad ; abdomen not extending beyond the wings. Wings rather short and broad, 
much rounded at the anal angle, the costal margin of the primaries almost straight ; the neuration almost 
as in Eupalia, but the cells of both wings considerably shorter. The legs rather long and stout. 
The female larger than the male, the body slightly longer, and the palpi quite small. 
This genus includes a single very distinct species from Mexico and Guatemala; 
Vipsania will be known by the extreme length of the palpi in the male and other 
characters. 
1. Vipsania anticlea, sp. n. (Tab. XXIII. figg. 83,92.) 
Male. Primaries bright golden-brown, with all the veins dark reddish-brown, and a reddish-brown line crossing 
the middle from the apex to the inner margin nearest to the base; secondaries uniform dark silky-brown: 
head and palpi dark reddish-brown ; the front of the thorax and the tegule bright yellow, the rest of the 
thorax and the abdomen reddish-brown; legs brown; the underside of both wings pale yellowish-brown, 
with the veins slightly darker in colour. The female considerably larger than the male and much paler 
in colour. Expanse, g,1} inch; 9,14 inch. 
Hab. Muxico, Jalapa (Hége); Guaremana, Cerro Zunil 4000 feet (Champion). 
EUPALIA. 
Nyssia, Walker, Cat. v. p. 1132 (nec Duponchel). 
Eupalia, Walker, Cat. xxxv. p. 1927. 
Neomiresa, Butler, Trans. Ent. Soc. Lond. 1878, p. 74. 
Thirteen species from various parts of the world were placed in Myssia by Walker. 
Eupalia of the same author, based upon a single species from Bogota, E. megasomoides 
(the type of which is in my own collection), is certainly generically identical with 
Nyssia,—E. megasomoides, indeed, being so closely allied to E. trimacula (Sepp) as 
to be doubtfully distinct therefrom. The name proposed by Butler (Joc. cit.) is not 
required ; this author gives, on what grounds I know not, WV. argentata as the type of 
Nyssia, Walk. 
In the British Museum there are several specimens, unnamed, agreeing well with 
Walker’s type of E. megasomoides. I think it doubtful if the insects from Africa, 
Madagascar, and India, placed in the genus Myssia by Walker, are generically identical 
with the New-World species. Three species inhabit Central America, two of which 
are apparently widely distributed in South America.
