1906.] ON THE LEPIDOPTERA OF THE TIBET COMMISSION. 485 



This variety was taken abundantly at Gyantze. No form of 

 semia7-gus lias hitherto been found in Tibet, so far as I know, 

 though it is found in the Pamir and Thianshan Mountains. 



31. Ltc^na pheretes Hiibn. 



Two forms of this species, which seem distinguishable, were 

 taken. One is from Gyantze, and is large, and, like the form from 

 East Tibet, of a duller blue above than the European insect. 

 The other, var. asiatica Elwes {L. plieretes var. pilaris Fawcett, 

 P. Z. S. 1904, ii. p. 138, pi. ix. ff. 5, 6), from Tungu, Khamba Jong, 

 and the Lhanak Valley, is smaller and has the hind wing below 

 suffused with blue on the inner half of the wing, by which when 

 fresh it may be distinguished from the West-Tibetan form lehanus 

 Moore. Some specimens are of a brighter more silvery blue above 

 than the majority, but I do not think this is constant, and it may 

 be due to a change of colour in the relaxing-box. The characters 

 by which Col. Fawcett has tiied to distinguish his var. pilaris 

 seem to me to be merely individual variation. 



32. LYCiENA ICARUS, var. 



Specimens from Lhasa are larger than the next species, and 

 agree with the form which Leech calls icarus from "West Tibet 

 in having black margined spots on the hind wing above. The 

 forms of icariis in Central Asia, of which Grtim. described several, 

 seem extremely variable. 



33. LYCiENA stoliczkana Feld. 



L. ariana var. arene Fawcett, P. Z. S. 1904, ii. p. 137, pi. ix. f. 4 

 Specimens from Gyantze and Khamba Jong agree best with this 

 species from Ladak, but are on the average larger. Two or three 

 of them are marked below almost as in «re«e, which I cannot look 

 upon as a distinct form. Staudinger thought that stoliczkana 

 might be a form of veiius, of which I have a good series from 

 various places in Turkestan, and all these may perhaps best be 

 treated as allies of e^'os, which has many local variations in 

 Cent]'al Asia. 



There were no specimens of Hesperiidse in the Collection. 



LEPIDOPTERA-PHAL^N^. 



By Sir George F. Hampson, Bt., B.A., F.Z.S., &c. 



The Moths taken by the Tibet Expedition were unfortunately 

 few in number, under 150 speciraens in all, and of these about 

 half came from low elevations in the Teesta Yalley and are 

 of comparatively small interest. Those, however, from Alpine 

 Sikhim and the Tibet Plateau, belonging to the Palaearctic fauna, 

 which I mark by an *, contain a large proportion of new and 

 interesting species, and larger collections from the same district 

 would be certain to contain many new forms.
