ground-colour paler and the red streak in discoidal cell of primaries broader and darker. 
Secondaries have a short broad tail, the anal ocellus is larger, and there is a submarginal 
series of red lunules and a marginal series of red spots ; beyond the cell there is a pale cloud. 
Under surface as in the male, but the red submarginal markings are broader, those towards 
anal angle forming complete oval ocelli ; the pale cloud on disc is more conspicuous than 
above. 
Ill Chiiiese specimens there is always a broad red streak at the base of 
discoidal cell of primaries ; the anal ocellus is well defined, and in some 
specimens the outer angle of primaries is suffused with greyish scales. On 
the under surface of secondaries there is sometimes a complete series of red 
submarginal lunules and usually a bluish cloud at outer angle. In one 
example there are three red spots on outer margin and in the first median 
interspace, remnants of the complete ocellus seen in the female. 
This species does not appear to be common in China. I have only 
received it from Chang-yang and Ichang, Central China, and from Chia-ting-fu 
in Western China. The only female that I have was taken at the last-named 
locality. 
Keferring to the occurrence of P. rhetenor in Sikkim, Mr. Elwes says : — 
"Found not uncommonly in the lower valleys, and up to 5000 or GOOO feet, 
from April to October. Two forms of the male exist, which I am not able to 
separate except by the colour of the hind margin of the fore wing, which in 
one form is more or less overlaid with grey or white scales close to the angle. 
There is also some variation in the white lunules which are present at the 
abdominal angle of the hind Aving, and in some specimens show more or less 
on the upper surface. The female form described as icarius is, without doubt, 
the female of this species. It is rare in Sikkim." {Ebves, Trans. Ent. Soc.

Hale. Ground-colour of all the wings black. Primaries and anterior portion of secondaries thickly 
sprinkled with whitish scales on each side of the nervures and neiTules, which gives the 
insect a grey and streaked appearance. Posterior portion of secondaries black with a bluish 
tinge, ornamented with five deep red crescent-shaped marks and an ocellus ; the latter is 
bordered with white on its external edge, and is situated at the anal angle. Along the outer 
margin are four small red marks, bordered externally with white, that situated between the 
extremities of the first and second median nervules being much the largest. Under surface :
