1886.] MR. H. J. ELWES ON THE GENUS PARNASSIUS. 33 
I have seen Erschoff’s type in the museum at St. Petersburg, and 
have little doubt that it is identical with Haberhauer’s, of which I 
possess one example ; but the fringes of the former are not so black 
and do not seem to be correctly represented in the figure. 
In general appearance the species is extremely similar to P disco- 
bolus, and, no doubt, varies in the usual manner. 
Though I cannot find Fedtschenko’s locality in a large-scale map 
of Turkestan, yet it cannot be very far from the mountains where 
Haberhauer found the species; and neither he nor other explorers 
seem to have met with it further north or east, whilst to the south 
and west are no mountains at all connected with this range’. 
P. pavipis. 
Parnassius davidis, Oberthiir, Et. Ent. liv. iv. p. 23, t. ii. fig. 2 
(1880). 
Beyond the single specimen which M. Oberthiir has described, 
nothing is known of the species, which seems to differ in nothing 
from P. nomion, excepting that the fringes of the wing are entirely 
black. It has also, as M. Oberthiir informs me, grey antennz 
ringed with black, and the club black, the legs grey, with the last 
articulation only black. It was discovered by the distinguished 
naturalist, Abbé David, in the Jehol Mountains north of Pekin, and 
must be either very local or rare, as no other specimen was ever 
procured by him in his numerous journeys in the north of China.

This species, sent by Bremer to Felder as P. delius, is undoubt- 
edly a good and distinct species, very variable in colour, but always 
to be recognized by its black antenne, plain black-and-white-edged 
fringe,and black pouch of the apollo type; but like those of its 
countryman, P. nomion, the pouch is more prominent and less 
covered by hairs. The veins are always covered with black scales, 
as in the mnemosyne group. In the number and colour of the ocelli 
it is extremely variable, some specimens having no red markings on 
either wing ; but the majority have three or four on the hind wing, 
and some have two, or even three, on the fore wing as well. ‘I'wo 
fresh females from Khabarofka, one of which is without a pouch, 
have the fore wings (which are without any red) strongly tinged 
with yellow; but out of nine males and nine females in my col- 
lection, not one presents the slightest deviation from the characters 
of the species, excepting that the antennz of some pale-coloured 
males from the Amur are faintly ringed with whitish. 
1 Since this was in print, I have received aspecimen of P. honrathi from the 
Grand Duke Nicholas, collected by M. Grumm Grshimailo at Agwas Potasuk, 
which I believe to be in the mountains of Karategin,
