with the same broad band, though the spot in the discoidal cell and that between the first and second subcostal 
nervures are not so large as they are on the upper side, nor so deep in colour ; it is rosy white, with the outer 
ends of the second, third and fourth, and the fifth entirely, rose-colour ; the base of the wing has two spots of 
scarlet.

A specimen of the male in the collection of Mr. Wallace differs in having the oblique band on the primary 
wings shorter and broader than on the specimen described above.

Female. PI. VII. f. 3. — “Above, anterior wings black, the disc with a large whitish spot divided by the 
median nervure, below which is a spot composed of scattered whitish scales, outer edge with indistinct whitish 
spots between the nervules. Posterior wings dentate, crossed beyond the cell by a broad band composed of six 
spots of a dull crimson, externally paler, and tinged with buff, the first roundish, the second, third, fourth and 
fifth somewhat wedge-shaped, the sixth nearly square ; outer margin dentate, cilia between the teeth whitish. 
“ Below, anterior wings as above ; the posterior wings with four spots at the base and a line along the abdominal 
margin bright crimson ; the transverse band paler than above. 
“ Head black, with two red spots behind ; antennae short, black. Thorax black, spotted with red below ; pro- 
thorax with two red spots above. Abdomen black, with two lateral red spots at the base. 
“ This species is closely allied in form to P. Ilus \_Evagoras\, but is at once known by the different position and 
form of the white spot on the anterior wings and the broader, differently-coloured band of the posterior. Its 
short antennae also are a good distinguishing character, giving somewdiat the appearance of a Parnassius .” —

The width across the wings is 3" 1'".

Male. — The primary wings deep black, with a few white marks between the nervules next the posterior angle ; 
a small white space, which is divided into three small spots by the anterior part of the median nervure and the 
base of the first median nervule. The posterior wings deep black, with the outer margin between the nervules 
white; a transverse curved band of bright carmine, which touches the nervure that forms the discoidal cell and 
is divided into six distinct lengthened spots by the nervules ; the first from the inner margin short, broad, and 
apparently divided into two ; the second and third the longest ; the two next gradually decrease in size, while 
the sixth is the smallest and subquadrate. 
The under surface of the primary wings is bronzy black, showing the same white mark in the middle as is 
exhibited on the upper side. The under surface of the secondary wings bronzy black, with the outer margin 
between the nervules white ; the transverse band below the discoidal cell is composed of smaller spots than on 
the upper side, and they are huffy white, with the hinder part crimson ; the base of the wings is ornamented 
with four large spots of deep crimson, and a line runs along the inner margin of the same colour. 
The width across the wings is 3" 8'". 
Female. — Like the figure (PI. VII. f. 3.), but is much larger, being 3 inches 10 lines across the wings. It 
also differs in having a larger space of white in the fore part of the discoidal cell of the primary wings, and 
in wanting the minute spot of white scattered scales below the second median nervule.
