1886.] MR. H.J.ELWES ON THE GENUS PARNASSIUS. 41 
took a single pair at Narka, in the province of Rupshu, which were 
described and figured by Felder. Two females in the Hewitson col- 
lection are marked Darjeeling, but there is no evidence that they 
came from Sikkim ; and though both have larger red ocelli on the 
hind wing than the Ladak specimens I have seen, yet they are pro- 
bably from Atkinson’s collection, which was made at many places 
in the Himalaya as well as at Darjeeling. M. L. de Nicéville, 
who is the only living entomologist who has seen this species alive, 
took three specimens (of which a pair are now before me) on July 
18, 1879, on the Baralacha pass, north of Lahoul, at 18,000 feet. 
Both of these have small ocelli on the margin of the hind wing, three 
of which in the 9, and one in the ¢ have bluish pupils. The male 
has no red markings at all, whilst the 9 has two ocelli in the usual 
place on the hind wing ; none that I have seen have the red ocellus 
on the costal margin of hind wing, which is found in all specimens 
of P. delphius and P. siaudingert. The fringes and antennze, however, 
agree perfectly with those of P. delphius, excepting that the antennee 
ofthe Q P. stoliczkanus are all black ; and though I hardly consider 
that the few specimens of this species existing show any structural 
characters of sufficient importance to separate them certainly from P. 
delphius, yet the absence of the costal ocellus on the hind wing would 
if constant be a good secondary character of distinction ; and there 
appears to be some difference in the internal structure of the pouch, 
though its external appearance is nearly the same as that of P. delphius. 
In a very interesting account of his journey through the Alai 
Mountains in the southern part of Khokand, M. Grumm Grshimailo 
describes a new species of Parnassius shortly, under the name 
of P. romanovi, which, though I have not yet been able to 
see a specimen, is possibly a form of this, but more probably 
allied to P. charltonius. He says :—‘‘The fore wings like delphius, 
the hind wings show a great red patch of 1 centimetre in 
diameter, a second of much smaller dimensions, and a band which is 
formed of three red marks; behind this red band, nearer the outer 
margin, are five beautiful blue ocelli surrounded by black shining 
scales.” 
This splendid insect was found near Katta-Karamuk, and also at 
Karasu, on the north side of the Tersagar pass, 10,000 feet, in com- 
pany with P. actius, P. staudingeri, var. nova, Parnassius sp., and 
many splendid species of Colias and other insects. 
Another new form, named, but not described, by the same explorer, 
is Parnassius cesar, which was found at Kizil Art, on the Alai 
Pamir plateau, at a great elevation, and said to be a splendid, quite 
unique species of great variability, and will no doubt be soon pub- 
lished in the Grand Duke Nicholas’s ‘ Mémoires sur les Lépidopteres,’ 
which have already added so much to our knowledge of Russian 
Lepidoptera. 
It will be impossible to say where these species belong in the 
genus, until they are fully described and figured *.

Duke Nicholas Mikhailovitch of Russia, two pairs of P. romanovi, which is
