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 ^.

 (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 antennae 

 ringed with black, and the club black, the legs grey, with the last 

 articulation only black. It was discovered by the distinguished 

 naturalist. Abbe David, in the Jfhol 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. 



P. BREMERI.

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 autennse, 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. Two 

 fresh females from Khabarot'ka, 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 antennae of some pale-coloured 

 males from the Amur are faintly ringed with whitish, 



^ Since this was in print, I Lave received a specimen of P. honrathi from the 

 Grand Duke Nicholas, coUecced by M. Grumm Grshimailo at Agwas Potasuk, 

 which I believe to be in the mountains of Karategiu,
