32 PARNASSIUS. By H. Stichej,. 



last abdominal segment as a broad lialfring, tlat bladder-shaped, posteriorly acuminate. Apparently only 

 3 specimens known (2 cfcf, 1 ?), from Central Tibet, Mts. of Burkhane - Buddha (Amdoj, at an altitude of 

 4600 m. 



szechenyi. P- szechenyi Frk. (15 e) is distinguished by a very broad vitreous margin to the forewing, this band 



together with the submarginal one forming a broad distal area which is divided by a row of white con- 

 tiguous halfmoons proximally sharply bordered with black; costal and hindmarginal spots tilled in with pale 

 red, of the costal ones at least the posterior. Hindwing with large, red, white-pupilled ocelli, broad black 

 posterior area strongly irrorated with white, and two large black anal S])ots with blue tilling, from which 

 emanates forward an anteriorly vitreous grey and posteriorly black submarginal band. Underside of a pec- 

 uliar greasy gloss, somewhat yellowish, most markings only feebly shining through. Shaft of antenna and 



germanae. fringes of wings whitish. Amdo (Kuku-nor), North-East Tibet. — germanae AuM. is a form in which both 

 sexes, but especially the ?, have the disc of the forewing shaded with black; hindwing with dark marginal 

 band, the submarginal band separated into spots, the large blue-centred anal spots being accompanied further 

 forward by two similar spots and a blackish subapical spot. Ta-tsien-lu, Western China. 



Orleans. P. Orleans Oherth.*) (13c). Ground-colour with a feeble yellow tint; forewing with the costal spots 



connected, band-like, including 2 or 3 red dots, hindmarginal spot likewise frequently filled in with red, 

 between these spots a blackish discal shadow; marginal band moderately wide, interrupted by narrow white 

 marginal spots; submarginal macular band deeply incised. Hindwing with large, red, white-centred ocelli, 

 1 or 2 anal spots, mostly also filled in with i-ed, and with a submarginal row of 4 or 5 black spots partly 

 filled in with blue. ? more sharply marked, the costal spots of forewing connected with the hindmarginal 

 one by denser black shading, the submarginal spots of hindwing larger, brighter. Apart from these char- 

 acters the general aspect very similar to that of P. eversmanni. Ta-tsien-lu, Western China. — In the ? of 



groumi. the smaller form groumi Oberth. (16 b) from Amdo (Kuku-nor) the red is usually absent from the spots of 

 the forewing, the spots themselves being very strongly marked, the black discal shadow stronger, ground- 

 colour of wings purer, submarginal band of forewing separated into spots and abbreviated, ocelli of hind- 

 wing bright red, anal spot black. 

 cephaius. We place here P. cephalus Gr.-Grsli. (16b), which hashitherto been treated as being allied with P. delpliius, 



but which must be dealt with together with the following insect as a special form-:group on account of the 

 pouch of the ? being different (ROhl) from that of delpliius and agreeing (Verity) with that of szixheniji. 

 This species resembles steiioseinits Hunt: (see below). Ground-colour pure white; forewing with complete 

 blackish submarginal band and a sometimes abbreviated discal one, as well as with white and black chequ- 

 ered fringes. Hindwing with very narrow dark margin, two blue anal spots, which are continued anter- 

 elwesi. iorly by two further black spots and a submarginal band. Amdo (Sining). — elwesi Leech is somewhat 

 larger, being similar to the preceding and illustrw and having likewise black and white chequered fringes; 

 from the high plateau north of Ta-tsien-lu in West China; only one specimen known, bearing on forewing 

 an additional, diffuse, black streak between the cell-spots and a red dot between the radials within the ab- 

 breviated discal band ; no spot before hindmargin. Hindwing with large red ocelli and bright blue anal 

 spots, but without basal spot. A similar individual, without red spot on forewing and the ocelli of hindwing 

 partly (asymmetrically) reduced to black spots, has been recorded from Tongho, West China (Ch. Oberthue). 



delphius. P. delphius Iiversm. (cf 15d, ? 15e) is a species consisting of numerous forms. The type of name 



was recorded from the southern foothills of the Altai, having come from the Tarbagatai according to the 

 label of the original preserved in the Museum at St. Petersbourg, the species being known in an identical 

 form, or nearly, from the Alatau and Tianshan, as well as in slight modifications from the district of tiie 

 Issyk-kul and from North Fergana. Charactei's: Discal markings dull, submarginal band of forewing distinct, 

 hindmarginal spot absent as a rule; ocelli of hindwing l)right carmine, hindmargirtal spots black, blackish 

 hindmarginal area broad, 2 bluish black anal spots, a faint submarginal and narrow marginal band. — The 

 following aberrations occur with the principal form , being connected with it and with one another by all 

 caeca, intergradations : ab. caeca Donitz with plain black ocelli , from Fergana , presumably also as an abei'ration 

 namangana. among the other races. — ab. namangana >>tgy. (16a), markings sharper and broader, disc of forewing 

 more strongly shaded with black, hindwing with 2 larger blue submarginal spots and 2 smaller black ones, 

 these sometimes dusted with blue, hindmarginal spots red, from North Fergana (Namangan and Naryn) and 

 maximina. Kuldja. — ab. maximina i^tgr., larger, resembling albidus in shape, submarginal spots heavy, contiguous, hind- 

 wing almost without marginal band, but with 2 very large blue-centred anal spots and 2 likewise blue-scaled 

 infernalis. submarginal ones, by which tiiis form can easily be distinguished from all the others; Issyk-kul. — ab. in- 

 fernalis Khv. (15 f), forewing with enlarged black band which appears sharply defined on the white ground, 

 marginal band broad, hindwing below with red basal spots, which are sometimes absent; Alps of Osh (Fast 

 Styx. Fergana) and Kuldja. — ab. styx <S7r/c. (15 f), upperside for the greater part black, sometimes without a 

 trace of the white ground-colour, the bands only feebly defined, hindwing with large red ocelli margined
