PAENASSIUS. 
23 
Eur. i. 316. — Expands 3 in. Very close to P. Apollo, but the 
hind wings have a red spot at the base, and the inner margins are 
more strongly black ; all the wings have a hind marginal border 
of square black and white spots. Time of appearance, July 
(Boisd.). Habitat, Siberia. 
P. Bremeri, Brem. Lep. Ost. Sib. p. 5, T. 1, 3, 4. — Expands 
2*50 in. Fore wings with only two black spots. Hind wings 
white, without any marginal spots ; inner margins very black ; 
there is a red spot at the base, and two light red spots placed as in 
P. Delius, small and square in the male, but larger in the female. 
Habitat, Siberia, chiefly in the Amoor district. 
P. Apollonius, Evers. Bull. Mosc. (1847), iii. 71 ; H.-S. 636, 7. 
— Expands 2*50 in. All the wings have a row of black spots 
running parallel to the hind margin. The fore wings have two 
black spots and three or four red ones ; the hind wings have a red 
spot at the base, besides the usual ones found in the allied species. 
This is undoubtedly the handsomest species of the genus : it is 
rare in collections on account of its exceedingly circumscribed 
habitat, which is limited to the district immediately south of 
the Altai. 
P. Delius var. Iiiterinedius, Men. Eu. i. p. 72. A small form 
of P. Delius from the Altai. — Expands 2-40 in. The male has a 
black spot in the centre of the hind margin of the fore wings and 
two conspicuous red ones near the costa. 
P. Conjhas, Fisch. Ent. Pmss. ii. p. 242. — Expands 2-40 to 
2*50 in. Wings more thickly clothed with scales than in others 
of the genus, creamy white, rather thickly speckled with black 
scales. The fore wings have the hind marginal and costal spots 
dotted with crimson. There is no red basal spot on the upper 
surface of the hind wings, but there is a row of black spots running 
parallel to the hind margins. Habitat, South and East of Siberia. 
P. Actius, Evers. Bull. Mosc. (1843), p. 540; H.-S. i. 634. — 
Expands 2 in. Very much resembles P. Nomion above, but is 
much smaller. The hind wings have no red spot at the base, 
but there is a chain of black spots running parallel to the hind 
margin, and the two red eye-like spots have very broad black 
rings. Beneath, the hind wings have the red basal spot very
