Review of the Species. 
A. Margin of forewing at vein 4 or 5 distinctly angular, dentate or indented. Forewing with 12 veins. 
a. Hindwing at the end of vein 1 b distinctly tailed. Forewing above with a large black spot at the end 
of the discal cell and sometimes also with such a dot in the cell. Hind wing above with a coherent, but 
posteriorly often disappearing black postdiscal band. 
*. A large species with an expanse of 40 to 55 mm. Forewing above with a black coherent discal band 
which is in the area 1 b generally united with the broad black marginal band. The postdiscal band 
of the hindwing only reaches to vein 2 and is in front very much widened. Ph. sardonyx. 
**. A smaller species with an expanse of about 30 mm. Forewing above with a very broad black discal 
band entirely enclosing the discal spots. Hindwing above at the base and at the costal margin broad 
blackish; its postdiscal band reaches to the proximal margin. Ph. phosphor. 
(3. Hindwing at the anal angle sharply extended, but not tailed. Both wings above with 5 to 7 separate 
black di.scal spots. 
*. Both wings above at the base broadly darkened with a bright silvery blue lustre. 
f. Hindwing beneath almost uni-coloured ochreous-yellow without silvery spots. Ph. osbecki. 
ft- Hindwing beneath with several irregular or H-shaped silvery spots. Ph. thysbe. 
**. Both wings above almost as far as the base orange-red without any blue. Hindwing beneath variegated 
with silvery spots. Ph. palmus. 
B. Margin of forewing uniformly rounded. Hindwing at the anal angle only shortly extended or angular. 
a. Both wings above at the base broad black and densely scaled blue. Forewing with 12 veins. 
Ph. pyroeis. 
(3. Wings above not blue at the base. 
*. Fringes of wings unspotted or with light spots between the ends of the veins. 
o. Fringes of wings broad black with large white spots between the ends of the veins. Hindwing 
beneath with golden or silvery spots. Forewing above with 5, hindwing at most with three black 
discal spots. Forewing only with 11 veins. Ch. chrysantas. 
oo. Fringes of wings not or only indistinctly spotted light. 
§. Hindwing above without discal spots (or only in 5 and 6 with small dots) and only with 
more or less united black marginal spots. Forewing with 12 veins. 
1. Hindwing above at the costal margin not or narrowly darkened; forewing above with 
a transverse row of 3 to 7 often almost contiguous discal dots. Ph. lycegenes. 
2. Hind wing above at the costal margin at least as far as vein 6 broadly blackish-brown. 
Forewing above only with 1 to 3 quite separate discal dots. Ph. lyncurium. 
§§. Both wings above with a postdiscal transverse row of 3 to 7 black discal spots. 
Hindwing beneath with silvery spots. Forewing with 12 veins. Ph. aethon. 
ft- Hindwing beneath without silvery spots. 
1. The black marginal band on the forewing above decorated with reddish-yellow 
marginal spots. Forewing with 12 veins. Ph. feltliami. 
2. Marginal band of fore wing above without spots. 
a. The discal spot in area 1 b of the forewing is situate nearer at the margin than the 
discal spot in 2. Forewing with 12 veins. Ph. chrysaor. 
b. The discal spot in area 1 b of the forewing is more remote from the margin than 
the spot in 2. Forewing only with 11 veins. Ph. zeuxo. 
**. Fringes of wings with white spots at the ends of the veins. Both wings above with distinct discal 
spots or dots. Hindwing beneath with silvery markings. Forewing only with 11 veins. — Chryso- 
ritis Btlr. Ph. oreas. 
Ph. sardonyx Trim. By its size and the shape of its wings this large species approximates the species sardony. 
of the first group, by the scheme of markings obove it fits best into this group, but by the marking of the 
hindwing beneath it deviates from all the other species. The margin of the forewing is at vein 4 distinctly angu¬ 
lar and that of the hind wing at the ends of the veins dentate and at the end of vein 1 b with a short tail. 
The $ is smaller than the $ and has more pointed forewings with an almost straight margin. Wings above 
yellowish-red with black markings, at the base narrowly darkened, forewing with a black marginal band of
