upper side slightly indicated ; the female on the underside is greyish 
buff slightly shaded with brown, especially in the middle, with the 
dark markings of the upper side slightly indicated, the legs flesh- 
coloured. The antenne of the male are short and about 26-jointed, 
each of the joints (except two or three at the tip) emitting four long 
branches. The female antenne are 25-jointed, each joint emitting 
a short brauch on each side at its extremity. The female has the 
branches of the antennze shorter than those of the male.

This species is at once distinguished by the singularly acute fal- 
cated form of the fore wings, which peculiarity is probably less 
strongly marked in the female; supposing as I do that the unique 
specimen in the British Museum is a male, although the compara- 
tively narrow antennz might seem to indicate the opposite sex. The 
fore wings on the upper side are dark rich red-brown, the apical mar- 
gin being dark ashy. They are marked near the base with a much- 
interrupted and slightly-indicated luteous striga; in the middle is a 
moderate sized oval ocellus, dark brown, surrounded by a slender 
ring of pale luteous scales, and with a very small greyish white lu- 
nule in the middle; beyond the ocellus is a regular black line run- 
ning from the apex to a little beyond the middle of the inner mar- 
gin, where it is marked with a few pale scales. Hind wings on the 
upper side rich chestnut-red, with the outer margin brown, and 
clothed with brown hairs along the anal margin; in the middle is a 
large ring of black, outside of which is a slender circle of fulvous 
scales, and in the centre is a rather small oval black spot crowned 
with a slight white lunule. On the under side the wings are dark 
fulvous-red, with a dusky apical margin, the fore wings with a black 
central circular spot inclosing a white dot, and the hind wings with 
a minute white transverse dot visible on the upper side in the centre 
of the large ocellus. The antennz are short, 26-jointed, each joint 
(except three or four of the terminal ones) emitting four moderately 
short branches, gradually shortening towards the tip. 
This species seems to approach near, if indeed it does not belong 
to the subgenus Hyperchiria of Hiibner (Verzeichniss, p. 155), Jo, 
Boisduval, the species of which are especially American. The trans- 
formations of one of the species (Saturnia Metzli from Mexico) have 
been recently illustrated by M. Sallé, in the ‘Revue de Zoologie,’ 
2nd series, tom. v. (1853) p. 171. pl. 5.
