:M PARNASSIUS. By H. Stichel. 



of forewing complete , the discal one posteriorly sometimes sepaiated into spots , hindwing with narrow 

 marginal band, 2 — 4 blue-centred submarginal spots, being preceded by a narrowly shaded band; tiie an- 

 terior ocellus sometimes absent, or reduced to a black dot. Otherwise similar to the figure of namanguna. 

 acdestis. — acdestis Gr.-Grsh. (16 b) is best placed here. Hindwing with very narrow marginal band, the submarginal 

 spots isolated, small; the ultraceliular costal spot of forewing continued by grey scaling, forming an .S-shaped 

 band. Amdo (Sining). — In West China (Tongho) there occurs a uniformly grey race which, in aspect, 

 reminds of the ? of dcljjhiiis (verus). being however more abundantly dusted with grey on the disc of fore- 

 cinerosus. wing and in the basal half of hindwing; this form may be named cinerosus*) aiibsp. uor. — A subspecies 

 lampidius. remarkable especially for its small size is lampidius Friilist. from South Tibet (Khamba-jong) (not Sikkim). 

 Ground-colour pure white, the cf resembluig daudingeri ; cell-spots and marginal band of forewing narrowed, 

 also the discal band narrower, being obtusely angulate behind cell. Hindwing black from base to the ocelli 

 and to near the anal angle, the strongly black-bordered ocelli both distinctly centred with red, at anal angle 

 2 blackish dots, near the distal margin a narrow grey band. ? with lighter vitreous bands on forewing and 

 larger, light carmine, ocelli on hindwing. At the base of hindwing a pale red spot in cf and ?. — The ?? 

 of all forms of delphius have pouches which encircle the abdomen belt-like, being broader than high and 

 ending in two points. 



5. Acco-Group. 



The species of this and the next group form a separate section on account of the subcostals 1 and 



2 being partly or entirely merged together. 



acco. P. acco Gray (16 c) is a rare species of which the name -typical form is known from Kashmir. 



Forewing usually with 3 complete bands distally of cell, the proximal one sometimes shortened or narrowed; 

 hindwing with red basal spot, the ocelli small, with reddish or whitish centres, near the distal margin a row 

 of black cunei- or luniform spots, the marginal band itself with a black interrupted dusting; in the ? the 

 red spots somewhat stronger, the pouch baggy, encircling the abdomen, grooved below, ending in two points. 

 Ladak, Barren Mts., Karakorum (3500 m), Sikkimese-Tibetan frontier. — Specimens from South Tibet have 

 gemmifer. received the name gemmifer Fruhst. ; recognizable by the darker marginal band and by the deeper red and 

 broadly black-edged ocelli of hindwing. 



simo. P. simo Grag is a small and rare species from Kashmir (Ladak) with rather pointed wings; the first- 



described form differs from the following one only in the submarginal band of the hindwing being vestigial, 

 consisting of a row of small halfmoons, and in the discal markings of forewing being less complete. — 

 simonius. simotllus Stgi: (16d) flies in South Fergana (Transalai); rather larger, being recognizable by the narrow, 

 simulator, but sharply marked, submarginal band of hindwing. — The form from the Issykkul is simulator .sVr/c. (16 d), 

 which has on the whole a more sharply marked pattern; submarginal band of hindwing composed of pro- 

 boedromius. longed halfmoons. — boedromius Fiing. (16d), from Chin. Turkestan (Aksu), is on the contrary distingu- 

 ished by a reduction of the markings. On forewing the discal band almost entirely absent, no red spots 

 gylippus. either above or below, ocelli vestigial. — gylippus Friih.it., from Aksu , is to be regarded as an aberration 

 of the preceding or as a mountain-form; bands again widened and intensified and ocelli red, the marginal 

 band of forewing especially wide, being almost merged together with the submarginal one, the two bands 

 acconus. being separated only by^ a line of small white spots. — acconus Fruhst., from South Tibet (Khamba-jong), 

 is similar to simonius; ground-colour yellowish, forewing witii sharply marked submarginal and discal bands; 

 hindwing with rather large red ocelli and a proportionally broad complete submarginal band , on underside 



3 elongate red basal spots and a red hindmarginal one. — The pouch of the ?? of this species is similar 

 to that of the previous, but narrower, being tubular. 



tenedius. P. tenedius Frersm. (16c) deviates somewhat from the general aspect of the group, cf with the 



ordinary cell-spots, the central one rounded, further with an abbreviated band distally of cell bearing 2 more 

 or less distinct red dots; with narrow vitreous margin and a submarginal row of sharply marked small black 

 spots. Hindwing with red basal spot; ocelli small, at the apex of cell a small black streak, near the edge 

 a row of small black spots; the spots stronger below, between the posterior ocellus and the anal angle a 

 complet chain of usually red-centred spots which shine through above, basal spots much prolonged. ? more 

 strongly marked, the costal spots of forewing more profuse!}' red, the hindmarginal Spot being also filled in 

 with red; black-grey abdominal area of hindwing wider, the anal spots marked also on upperside, all the 

 red paler, the distal margin blackish. — East Turkestan: Issykkul; South Siberia: Altai, Sajan, Kentei Mts. ; 

 upper districts of the Lena and Viljui (July), Jakutsk. 



6. Charltonius-Group. 



This group, the last, contains the finest species of the genus. 

 imperator. P. imperator Ohertli. (16e) is the largest representative of the group. Forewing broad, rather pro- 



fusely dusted with grey, the dusting denser behind the cell, forming an almost band-like prolongation of the
