DIRPHIA. 195 
daries uniform pale brown, with an indistinct waved paler submarginal band, all the veins dark brown, the 
fringe yellow; underside uniform pale brown, both wings being crossed by a dark brown line bordered on 
the inner edge close to the apex with white, and each with a dark-coloured spot at the end of the cells: 
head, thorax, and the underside of the abdomen yellowish-hrown, the upperside of the latter black banded 
with yellowish-brown; the anus and antennz pale yellowish-brown. The female differs from the male. 
in being more uniform in colour, with the bands crossing the primaries very much more indistinct- 
Expanse, ¢ , 23-33 inches ; 9, 33 inches. 
Hab. Mexico, Jalapa (Hoge). 
This insect appears to be common at Jalapa, whence Hége sent a large number of 
specimens ; we have no evidence of its occurrence in any other locality. The female 
slightly resembles Ormiscodes lasiocampina, Felder, though very different from that 
species, the male of which is unknown. JD. hégei varies considerably in colour and 
size ; several specimens of the male are only 22 inches in expanse, and much darker in 
colour. The females do not show any variation. 
5. Dirphia rosea, sp.n. (Tab. XX. figg. 7¢, 8 2.) 
Male and female. Primaries brown, shaded with rose-colour, a rose-coloured band extending from the costal 
to the inner margin, the base very dark brown, a semicircular brown patch at the apex, a waved rose- 
coloured submarginal band extending from the apex to the anal angle, a brown spot bordered with rose- 
colour at the end of the cell; secondaries bright rose-colour from the base to beyond the middle, from the 
middle to the outer margin shaded with brown, two indistinct wide waved black lines crossing the wing 
from the costal margin near the apex to the inner margin near the anal angle, a black line at the end of 
the cell; underside uniform pale brown, shaded with rose-colour, the black bands as above: head and 
thorax dark brown; abdomen brown, banded with chrome-yellow, covered with long whitish hairs ; 
antennz of the male deeply pectinated, of the female simple, pale yellowish-brown ; legs dark brown, 
banded with red. The male is slightly paler in colour and considerably smaller than the female. 
Expanse, g, 2% inches; 9, 34 inches: 
Hab. Mexico (coll. Staudinger), Jalapa (Hoge). 
A female specimen in Dr. Staudinger’s collection is much smaller than those 
obtained by Herr Hoge. 
This beautiful insect is not nearly allied to any described species.

I have only seen a male and female example of this apparently rare species, which 
we now trace northwards to Costa Rica, from our country; the male is considerably 
smaller than Cramer’s figure of the female. A female specimen from Ecuador in my 
collection agrees well with the figure, though it is much brighter in colour and rather 
larger. Dr. Staudinger’s example of the female has a white line at the end of the cell 
of the secondaries, which I can trace on the underside of my Ecuador specimen.
