size. The ocelli of the secondaries are of a very pale 

 pinkish tinge. This northern form, modified in the oppo- 

 site direction, as compared with the type from przevalskyi, 

 Alph., haileyi. South, and gemmifer, Fruhst., has full right 

 to receive a special name. I dedicate it to the eminent 

 British entomologist Sir George Hampson. 



Parnassius maharaja, sp. nov. (Plate LIV, figs. 1, (J; 



2,?.) 



The correct position in the genus of this new species is 

 rather doubtful. The pouch of the female shows, how- 

 ever, that it has close affinity with Parnassius cephalus, 

 Gr.-Gr., and szechenyi, Friv. 



The male is white, with a fuscous marginal band and a row of 

 dark submarginal lunulae on the primaries. Between this row 

 and the discocellular is a grey shade at the costal margin. The 

 two black markings of the dark discocellular are well developed. 

 A grey patch in the middle of interspace 1 near the inner margin 

 is indistinct. The secondaries have a dark marginal band and a 

 row of 'evanescent dark markings. Instead of the ocelli there is a 

 minute dark marking in the interspace 5 and a larger one on the 

 costal margin. In the same interspace 7 there is another dark 

 marking between the ocellus and the basis of the wing — a character 

 typical for acco, szechenyi, sinio and charltonius. 



The female has better-developed dark markings, especially on 

 the secondaries, where a complete row of antemarginal markings 

 is present, the two subanal spots being heavier and of a somewhat 

 triangular shape. The discal ocelli are larger, though of a diffuse 

 fuscous colouring, with some pale reddish scales in the upper one. 



The cilia of both sexes are black, as in simo. 



The ground-colouring of the underside of the hindwing, as well 

 as of the apex of the primaries is of the same reddish tinge as in 

 acco-przevalskyi. There are no white scales along the veinings as 

 in the latter conspecies. The legs are slightly pinkish. The size of 

 this species is that of large delphius forms ; the pointed and extended 

 shape of the forewings is very much that of a gigantic simo. 



Caught on desolate stony slopes near the crest of the 

 Tagalang-la Pass (Rupshu), 18,000 feet, and in the vicinity 

 of Sugetdavan (Chinese Turkestan). I have unmistakably 

 seen a specimen on the Depsang plateau, 17,000 feet, in 

 the Karakoram region, but could not catch the butterfly.
