480 DE. H. J. ELWES, SIR G. HAMPSON", AND MR. J. H. DUERANT [May 1 



name of epcq^hus for this insect, I venture to maintain the opinion 

 expressed in my paper on the genus above cited, that it should 

 proj)erly be called jacquemonti Bdv. A few specimens only from 

 Tungu and Llianak. 



3. Paenassius imperatoe var. Augustus. 



P. augustus Fruhstorfer, Insekten Borse, xx. 



A fair series of specimens taken at Tungu and Khamba 

 Jong seems to show that this form is not sufficiently unlike 

 impeixUor to be distinguished, though some of the specimens are 

 more yellowish in tint and more heavily marked than those from 

 East Tibet, to which they come closer than to the form im2:)eratrix 

 Alph., with which Fruhstorfer compares it. 



4. Paenassius haedwickei Gray. 



Several specimens from Tungu ; small and as variable as usual 

 from this district. 



5. PiEEis (Apobia) duberxaedi Obth., var. chumbiensis Mcev. 

 J. A. S. B. Lxvi. p. 563, pi. i. f. 6. 



A number of specimens from Gyantze, taken in June 1904, are 

 smaller on the average than the type, and come nearer to the form 

 from N.E. Tibet which has been called koslovi by Alpheraky. 



6. PiEEIS BEASSICiE L. 



A few specimens from Gyantze do not differ from those found 

 in Alpine Sikhim and usually called var. sikkimensis. 



7. PiEEis CANiDiA Sparrm. var. pal^arctica Stgr. Stett. ent. 

 Zeit. 1886, p. 198. 



A good deal of variation is shown in the series sent from Tungu, 

 Gyantze, and Lhasa, most of them being heavily marked and dai'k 

 on the under side. 



8. PiERis MELETE var. AJAKA Moore, P. Z. S. 1865. p. 490. 

 A few from Tungu and Gyantze. 



9. CoLiAS BEETLLA Fawcett, P. Z. S. 1904, ii. p. 139, pi. ix. f. 8, $ . 

 (Plate XXX YI. fig. 13 d.) 



C. nioia, id. op. cit. p. 140, t. 9. f. 9, 5 . 



A large series of this fine species from Khamba Jong and 

 Gyantze shows so much variation that I am inclined to believe 

 that C. nina is nothing more than an extreme form of the female. 

 A mtich greater range of variation is found in some of the Tibetan 

 Colias, especially in the females of eogene ; and some females of 

 the var. arida Alph. from N.E. Tibet are very similar to this. 

 The specimens taken at Gyantze are on the average much darker 

 in colour than those from Khamba Jong, and without the inter- 

 mediate forms one might be able to distinguish them.
