Parnassius acdestis, Gr.-Gr., subsp. rupshuana, nov. 

 (PlateLII,fig.5,c?; 6,?.) 



Differs from the type forms especially by the position 

 of the antemarginal markings of the hindwdng. These 

 markings are reduced in size, and run further inward at 

 a greater distance from the outer margin. Generally it 

 is only the round black spot in cell 3 that is compara- 

 tively conspicuous. It has no blue centre. The next 

 lunule in cell 4 is particularly strongly curved inwardly. 

 The white marginal lunulae of the ground-colouring on 

 the primaries are also removed further from the margin 

 in comparison with acdestis. The shape of the primaries 

 is more pointed at the apex, and the secondaries present 

 a slightly pronounced angle in the outline on the outer 

 margin of cell 4. 



Locality. Rupshu, Tag-alang-la, 17,000-18,000 feet, VII. 



Parnassius acdestis, subsp. ladakensis, nov. (Plate LII, 



%• 7, ?.) 



This is nearest to the typical race from Kuku-nor. The 

 shape of the wings is rounder than in rupshuana. The 

 dark markings of the primaries are not so developed as in 

 the latter form. The chief distinctive character of lada- 

 kensis and acdestis is connected with the position of the 

 antemarginal band of markings on the secondaries, which 

 is just as far removed from the edge in ladakensis as it is 

 in rupshuana. Judging by my single ladakensis female 

 from Shera-la (East Ladak), and comparing it with my 

 ten specimens of rupshuana, it may be stated that the 

 marking in cell 3 conforms more, by its shape and size, 

 to the corresponding character of the real acdestis. The 

 basal greyish area is somewhat lighter. 



I have found it useful to publish the figures of two little- 

 known new acdestis forms, described lately by Felix Bryk. 



Parnassius latonius (Plate LII, fig. 8, $), originally 

 described as an independent species, is but a very large 

 and heavily marked form of acdestis lampidius, Fruhst., 

 from Sikkim. There is a distinct red basal eyelet on the 

 hindwing. Two specimens of P. latonius have been found 

 at Kangma, South Tibet, near Shigatse. One of these 

 specimens I obtained through Bang-Haas in Dresden. 



Parnassius acdestis prianius (Plate LII, fig. 9, (^) has 

 been taken in Central Tian Chan near the Musart Pass.
