40 MR. H. J. ELWES ON THE GENUS PARNASSIUS. [Jan. 19, 
a botanist of St. Petersburg, in the Tarbagatai and A//akan Moun- 
tains.’ * It has since been taken abundantly by Alpheraky in the 
Thian Shan Mountains, above 9000 feet elevation, in July and 
August. It frequents steep stony mountains up to 12,000 feet, 
where there are great abundance of Saxifrages. Haberhauer also 
took it in the Alatau, and in the Sultan Hazret mountains, south of 
Samarkand, which form the western termination of the Alatau, in 
great quantity between the 10th June and the beginning of August. 
This last was described by Herr Bang-Haas as P. staudingeri, but 
after having seen large numbers of the two forms, three pairs of 
each of which are in my collection, I fail to find any difference by 
which they may be distinguished. Both are very variable, but both 
have the antennze, fringes of the wing, pouch of the female, and all 
important characters absolutely identical. 
Bang-Haas relies principally on the supposed broader fore wings, 
and the purer yellowish white ground-colour with much sharper 
blacker markings ; but when he wrote he had not yet received the 
specimens of P. delphius, collected in Ferghana by Haberhauer, which 
vary extremely. Some of these (? var. namagana) have blue ocelli on 
the hind wing, as in stoliczkanus. Some of the females of P. stau- 
dingeri (var. infernalis, Stgr.) are very dark, almost black in their 
ground colour, 
The antenne in this species are in the male sex black, but in all 
my six females the lower part is more or less grey, not distinctly 
ringed. The fringes are very narrow, whitish in colour, but some- 
times darker ; and, as Bang-Haas points out, the horny substance of 
the pouch forms a complete ring round the hinder segment of the 
body. 
Dr. Staudinger says it varies from a uniform grey colour with 
feebly marked blackish spots to a very dark colour with reddish- 
yellow, red, or yellow ocelli on the hind wings, and in one specimen 
two small red spots on the costal margin. The bluish scales of the 
two black round ocelli on the hind wing also seem to be often want- 
ing in the freshest specimens. I noted in his collection a very curious 
looking organ protruding from the abdomen of a male specimen of 
P. staudingeri, which, having some analogy in’shape to the pouch of 
the female, led Dr. Staudinger to think it was a hermaphrodite. This 
organ, however, which, owing to his kind loan of the specimen, I 
am able to figure (Plate II. fig. 14), is I believe only the ordinary 
male claspers protruded from the body, perhaps owing to forcible 
separation from the female.

(1865), iil. t. 67. figs. 2, 3 (1867). 
With regard to P. stoliczkanus we know but little, as it is an 
inhabitant of remote and inaccessible districts in Ladak and the 
northern frontier of the North-west Himalaya. The late Dr. Stoliezka

best modern maps,
