The antenne of the males are not very broadly feathered; they 
are 32-jointed, each joint emitting four branches of equal length, ex- 
cept about eight of the terminal joints, in which one of the pairs of 
branches gradually diminishes in length, and becomes obsolete in 
two or three of the terminal joints. The antennze of the female are 
less strongly feathered, and one of the pairs of branches becomes ob- 
solete in about seven of the terminal joints.

This curious species is at once distinguished by its very narrow 
wings and the large size of the glassy spots, especially in the hinder 
pair ; the body is black, with a white ring round the neck and a less 
distinct fascia across the hind part of the thorax. The antenne are 
very strongly branched; the fore wings are especially long and narrow 
and slightly falcate at the tip, which is rounded ; they are of a black 
colour, slightly tinged with chestnut, and powdered, especially along 
the fore margin, with grey scales. A narrow, straight, white striga 
extends from the base of the wing to the vitreous spot, where it is an- 
gulated, and runs towards the fore margin. The centre of the wing is 
occupied by a large, elongated, suboval heptagonal vitreous spot, which 
is not traversed by any transverse vein, the branches of the median 
vein being pushed so far backward, as to admit of its occupying so 
large a clear space; a narrow white fascia extends from its extre- 
mity to the costa, and from the middle of its hinder margin to the 
hind margin of the wing, the space between which and the apical mar- 
gin is varied with chestnut, red and grey scales and luteous patches. 
The tip of the wing is orange, with a chestnut patch and a white 
angulated line, below which is a large oval chestnut-red patch, bear- 
ing a black spot and divided into several parts by dark luteous lines. 
The hind wings are almost entirely occupied by a large oval glassy 
patch destitute of veins, the subcostal vein being pushed towards the 
costal margin, and the median one towards the anal margin, and their 
branches emitted at an unusual distance from the base of the wing ; 
the apical portion is coloured in the same way as in the fore wings, 
except that the luteous spots form a narrow, continuous, submarginal 
fascia, enclosing a series of transverse, black spots more or less united 
in pairs.
