les autres especes dii meme genre, parait iatermediaire eiitrc les P. apollo et phcehus. A leur 
cxtremite, les quatre ailes sout subdiaphanes, cette partie transparente etant precedee d'une 
serie de Imiules bordees de blanc exte'rieurement. Ent.re cette rangee de lunules et la cellule 
discoidale, ees ailes antdrieures offrent deux taches noircs, ordinairement marquees de rouge, 
ainsi qu'une autre tacbe situee au bord interne. Comme dans les P. plicelms et apollo, il 
existe encore uue tacbe noire a Textremite de la cellule discoidale, et une autre vers son 
milieu. 
" Les ailes poste'rieures ont leur gouttiere abdominale tres noire, et pre'sentent deux tacbea ocellees 
rouges, bordees de noir, et ordinairement blanches au centre : Tune situee au bord externe, 
I'autre vers le milieu. On remarque en outre a Tangle anal une tacbe noire allonges 
souvent marquee de rouge. Les quatre ailes sont en dessous a pen pres semblables au dessus ; 
seulement les posterieures offrent a leur bord, comme dans la plupart des Parnassiens, trois 
ou quatre tacbes rouges, dont on retrouve a peine la trace en dessus ; cnsuite, vers Tangle 
anal, il existe deux taches rouges tres distinctes, dont Tune arrondie et Tautre presque tri- 
angulaire. Les antenncs sont grisatrcs, fortement annelecs de noir." (Blanchard, I. c.) 
The following descriptions refer to the Chinese form (Plate XXXIII. 
tig. 3, d):— 
Male. Similar to P. jacqxwmoiiti, var. Jiimalayensis, Elwes, but the ground-colour is very much 
darker and the wings are less densely covered with scales and are more glossy in appearance, 
the submarginal band is composed of white bar-like spots bordered with blackish, in Jiimalay- 
ensis this band is formed of lunulate spots ; the central ocellus of secondaries is internally 
bordered by a pale bar ; the crimson spots are of a deeper colour, but that at anal angle is 
absent. Fringes as in Jiimalaijensis, but much more broadly chequered with black. 
Female. Agrees with the male, but is usually somewhat larger and yellower in tint. The pouch 
(represented under figure of the male, Plate XXXIII.) agrees in shape with that of 
himalai/cnsis, and varies in colour from dark brown to black.

Appears to be common in Western China at IIo\y-kow on the Thibetan 
frontier, where it occm-s at a great elevation. 
Fritz Eiihl, who describes this insect under my manuscript name thihetanus, 
or, as he writes it, tibetanus, states that it occurs at Ta-chien-lu ; but this is 
certainly an error, as this form has so far only been received from How^-kow, 
from w^hence I had a large number of specimens. It is, without doubt, 
nothing but a w-ell-marked local race of P. jacquemonti and is the darkest 
form of Parnassius known to me. The red spots vary in size and may be 
with or without w-hite centres ; some examples have three red spots on 
primaries, and in others there are no red spots on these wings. The 
female varies in colour from yellow to white according to the freshness of 
the specimens.
