of the prothorax is golden green, with the exception of two dorsal spots of velvety 
black.. The fergum of the rest of the thorax and abdomen is also black, but marked by 
three longitudinal golden green lines, one on each side of a medial one. ‘The pectus of 
the mesothoraz is black, marked at least by one oblique white fascia on each side. The 
wings are velvety black, with an undulated rim, the hollows of which are more or less 
slightly tipped with white. 
The upper side of the upper wings has eleven golden green transverse lines, which are 
narrowest towards the posterior angle'. The seventh of these lines from the humeral 
angle is bifid towards the anterior margin of the wing; and between the second and 
third line on the same anterior margin are two golden green linear dots, and a longer 
one between the ninth and tenth. 
The under side of the upper wings has the interior margin brown, but all the rest 
velvety black, with transverse lines of a bluish green colour. Of these the first six 
from the humeral angle are parallel ; and the seventh line, which is somewhat bifid at 
the anterior margin, meets at the anal angle of the wing the eighth line, which is trifid 
or even quadrifid at the anterior margin, and is by far the longest. The three or four 
apical lines are filiform, the ninth generally meeting the tenth at the anterior margin 
of the wing. 
The upper side of the under wings is velvety black, with a longitudinal broad discal 
band of a golden green colour, reaching from nearly the middle of the anterior margin 
to the anal angle, and which is only interrupted by two or three black spots towards the 
anal angle. The interior margin, fringed with blackish down, is also lined by a broad 
obscure green fascia, which meets the former band towards the anal angle, and which 
is interrupted by four, or even more, black transverse spots towards the same angle. 
The posterior margin has at least eight transverse golden green abbreviated lines, of 
which the fourth and eighth are the shortest, and the fifth is the longest. The tail of 
the wing is long, tapering, black, with the central line bluish green. 
The under side of the under wings is golden green, becoming more bluish towards the 
tail. The interior margin is fringed towards the scutellar angle with a cinereous down, 
and has four abbreviated parallel black transverse spots towards the anal angle. The 
anterior margin has eight abbreviated transverse black bands, of which the shortest are 
the first and sixth, counting from the humeral angle, and the longest the eighth, while 
the third and fourth, the seventh and eighth, meet each other towards the disc of the 
wing. The posterior margin has two black bands, of which the superior one is furcated 
towards the posterior angle.of the wing; and four or five large black spots towards the 
anal angle, which sometimes coalesce into two bands, of which the upper is abbreviated. 
The tail is bluish green, with the margins black.
