than ¢. F.w. very much like those of /. afcllo ? , 
but the outer costal spats have from one to three red 
centres. The inner marginal spot is conspicuous and 
often marked with red. H.w. asin ¢, but witha 
marginal transparent band. Black spots at anal angle 
often marked with red, generally a red basal spot. 
The two large red annular spots have sometimes a 
faint trace ofa black connecting line. Abdominal 
pouch a little larger than in P. apollo.

It frequents much more elevated situations than

colour is black, spotted with lemon-yellow, the head

50—55 mm. A small Asiatic variety of P. delius. 
The wings are purer white in colour, and the markings 
are smaller ; especially the red centred spots. The 
marginal transparent bands are much narrower than 
in the type. F. w. with a distinct inner marginal spot. 
?. Less dusky than in type. The inner marginal 
spot is more liable to be distinctly centred with red. 
The abdominal pouch is broader. Has., South 
Siberia, Kamtschatka, Turkestan. 
The North American var. s7znthews Doub. with 
its dark ab. hermodur Edw. greatly resembles the var. 
intermedius, it inhabits the Rocky Mountains and

b. var. sedakovit Mén, Aust. Parn. pl. IX., fig. 3. 
Smaller than yar. z¢ermedius. Somewhat more 
densely scaled, and with less extended transparent 
markings. The costal spots f. w. are reduced to two, 
and the central spot of h. w. to a black dot without 
any red centre. HAbs., Irkutsk, E. Siberia.

form of P. deléus. Wings duskier than in type. F.w.

red basal spots. Has., N.E. Siberia at an elevation 
of about 6,o00ft., Kamtschatka.

Smaller, and much whiter than P?. afol/o. All the

costal spots are often strongly marked with red, but 
not the inner marginal one. Transparent mar- 
ginal band, narrow but extending nearly the 
whole length of the margin. H. w. with the 
black inner marginal patch well defined, but not

costa and centre well defined, but none near anal 
angle. There isa more or less defined row of ante- 
marginal black spots, inclined to be triangular or

Has. A widely distributed species. It was first 
discovered in 1842, by M. Schrenck, on the elevated 
mountains in the neighbourhood of Tarbagtai; but 
has since been found throughout the whole of 
Turkestan, and on all the Alps of Songaria, as far as 
the beginning of the Altai Mountains (Aust.) It 
occurs at great elevations and in dry places, where 
saxifrage grows.

A 6 example of this new species received from Dr. 
Staudinger 1898 greatly resembles P. actzws in size 
and appearance, but in the f.w. the ante-marginal wavy 
band is very nearly absent. H.w. without the ante- 
marginal row of triangular spots, but with a narrow 
black undefined marginal band. z.s. with red basal 
spots larger and brighter red than in P. acfi2s. 
Margins less chequered than in that species.

This species, which certainly belongs to the afod/o 
group of Carinati, is distinguished by the decidedly 
yellowish or buff tinge of the ground colour, and by 
the dusky appearance of the wings, due to the 
presence over most of their area of black scales.
