Wings dull white, with a yellowish tinge. F.w. 

 with two black costal spots, the third external one 

 indistinct. Central area more or less powdered with 

 black scales. Marginal transparent bands well de- 

 fined. No spot near an. ang., or at most a very 

 slight ill-defined trace of it. 



H.w. with the ground colour clear in central area. 

 Base broadly black, more intensely in some specimens 

 than in others ; thus approaching var. infemalis. 

 Marginal band well defined, the narrow ante-marginal 

 band sometimes containing some black spots and ter- 

 minating in one or two isolated round black spots, with 

 a few blue scales in their centres. Costal and central 

 spots well defined, but not large ; the red colour of the 

 centre is not very brilliant, but rather inclines to 

 yellow or orange. Ground colour of °. wings some-

what whiter than in $ , and less powdered with black. 

 H.w. with a spot at an. ang. indistinctly marked 

 with red. Abdominal pouch light brownish-yellow. 

 Shafts of antennae lighter than in <?. U.S. h.w. in 

 both sexes with two dull basal red spots and one 

 near an. ang. ; these are absent in some specimens 

 from the eastern portion of the range, or else very 

 indistinctly defined ; but in those from the neighbour- 

 hood of Kokand and other localities in Turkestan 

 they are quite plainly marked.

a. var. infemalis Stgr. This variety differs from 

 the type in the increased intensity of the dark 

 markings, but chiefly in the extension of the black 

 basal patch on the h.w., which reaches as far as the 

 red-centred spots, themselves being larger than in 

 the type ; the two spots near the anal angle are also 

 larger. We may consider this form as a melanic variety 

 of P. delphius. Hab. The Alps of Och, Turkestan, 

 in the Kuldja district, at about 11,000 ft. 



b. ab. styx Stgr. S. E. Z. 196. Aust, Parn. 

 75. This name is given by Staudinger to a still 

 darker and more melanic form than the last, where the 

 wings are entirely suffused with dusky shading, except 



along the costa f.w. between the black spots. Hab.

c. var. staudingeri Bang Haas. B. E. Z. XXVI. 

 1882. Heft 1, pp. 163, 164. Aust. Parn. 79, 

 pi. XVIII. fig. 1. The specimen of this form I 

 have received from Dr. Staudinger resembles the 

 type above described, but the markings are all much 

 clearer and more pronounced. The outer marg. of 

 all the wings darker and less transparent. H.w. u.s. 

 without any red basal spots. Hab. Alps to the 

 south of Samarkand and other places in the province 

 of Kokand ; from VI. e. to VHI.b. Always above 

 8,000 ft. 



d. var. transiens Stgr. in litt. Aust. Parn. Sc. 

 pi. XVIII. fig. 3, illustris Gr.-Gr. Much resembles 

 staudingeri, but of a less clear white in the ground 

 colour. H.w. not so black at the base, and showing 

 a trace of a black spot at an. ang. Ante-marginal 

 spots near an. ang. elongated and without blue 

 centres. Red spots well defined, but light in colour, 

 connected by a thin black line. Basal red spots on 

 u.s. present, but faintly marked. Hab. Pamir, on 

 elevated plateaux. 



e. var. infumata Stgr. in litt. A remarkable form 

 in which the wings are of a brownish-white. The 

 markings well defined, but narrower than in var. 

 transiens. F.w. with a black spot near in. marg., 

 h.w. with the red spots well defined, but not con- 

 nected with a black line ; no spot near an. ang., the 

 two ante-marginal spots centred with blue. U.S. 

 h.w. with red basal spots faintly defined. Hab. 

 Turkestan.

white, which renders the markings more distinct, 

 especially the marginal and ante-marginal bands of 

 f.w. H.w. with three or four black ante-marginal 

 spots dotted with blue, and at an. ang. a distinct 

 elongated red spot, as well as the two usual spots, 

 which are well defined and bright in colour. U.S. 

 as above, h.w. with two or three red basal spots.
