92. Argynnis latJionia isscea, Doubl. 24 specimens, Lower Tsang Po and 

 Po Chu Valley, 7-10,000 feet, June and July ; Tawang, 10,000 feet, October. 



93. Argynnis clara manis, Fruh. 8 specimens in the high country south 

 of the Tsang Po, 10-15,000 feet, September. 



94. Argynnis gong, Ober. One worn female, Po Chu Valley, 10,000 feet, 

 July. 



95. Argymiis gemmatagenia, Ymh. (see Tplate). 24 specimens at 12-16,000 

 feet in the high country south of the Tsang Po in September ; in several the 

 silver colouring on the underside is replaced by yellow, and this variety may 

 be called fulva, no v. 



96. Argynnis eugenia rJiea, Groum. (see plate). 42 specimens caught at 

 12-16,000 feet at Lu on the Tsang Po and in the high country to the south 

 in August and September. 



These two species are very similar in general appearance. In genia vein 

 10 is emitted at the end of the cell, thus it falls in true Argynnis, while rhea 

 appertains to Moore's genus Boloria, as this vein is emitted well beyond the 

 cell. I would, however, remark that this feature is of little value from a 

 generic point of view, as in clara, Blanch, the vein is emitted well after the 

 end of the cell and in the race manis, Fruh, just after that point. In the 

 gemmata group, which includes eugenia and altissima, the pattern of the 

 hindwing below does not vary appreciably ; in gemmata. But, and its dwarf 

 race genia the silver spot at the centre of the costa is more or less upright 

 and square in shape, also the cinnamon red areas are broad and prominent : 

 in altissima and eugenia the spot mentioned is sloping and the red areas are 

 indistinct. Genia, if my identification is correct, is remarkable in that the 

 marginal black band, prominent in the other allied species, is absent and 

 the cilia are concolourous with the ground colour. Altissima appears to be a 

 good species ; vein 10 arises just after the end of the cell ; the forewing 

 is sharply pointed and the outer margin straight below that point ; all the 

 silver markings on the underside are narrow and elongated, while the 

 black spot near the base of cell 2 on the forewing above is placed nearer 

 the outer margin than in the other species of the group. Eugenia, Ever- 

 sman, is a species flying from South Siberia, through West China and 

 Tibet to the Himalayas ; vein 10 arises well beyond the end of the cell, 

 its origin being equi-distant between that point and the origin of vein 9 ; 

 in the nymotypicai Northern form the large silver spot crossing the end of 

 the cell on the hindwing below is quite short ; in the Tibetan race rhea, 

 described from Amdo, it is elongate as in gemmata. Mackinnoni, de N., from 

 the Himalayas, is, I am convinced, a race of eugenia and has nothing 

 to do with altissima ; it hardly differs from rhea, but the cinnamon red 

 areas below are rather more prominent and the cilia above are concolourous 

 with the ground colour instead of being whitish. 



97. Melitcsa sindura jezabel, Oberth. 102 specimens in the Po Chu Valley 

 and on the Tsang Po between Gyala and Du and just beyond the Kongbo 

 Nga La at 10-13,000 feet in July and August. The specimens appear to be 

 nearest to jezabel from Eastern Tibet. Above dark, the outer band 

 strongly developed ; below very brick red, the forewing often without any 

 discal markings. Specimens I have from Gyantse are very similar 

 differing only in the lesser development of the outer discal band on the 

 forewing above. Both are very different from the small dull Ohumbi VaUey 

 form sikkimensis, M. and are nearer to balbita, M. from Kashmir, though 

 smaller. 



98. Melitcea didyma agar, Oberth. 57 specimens mostly on the Tsang Po 

 between Gyala and Lhapto at 9-13,000 feet in July and August and a few
