484 DR. H. J. ELWES, SIR G. HAMPSON-, AND MR. J. H. DURRANT [May 1, 



24. Pyrameis indica Herbst, 

 One specimen from Kliamba Jong. 



25. Pyrameis cardui Linn. 

 Several specimens from Gyantze. 



26. PoLYGONiA c-ALBUM var. TiBETANA Elwes, Trans. Ent. Soc. 

 Lond. 1888, p. 197, pi. x. f. 1. 



A few specimens from Gyantze agree with those formerly 

 received from the Chumbi Valley, 



27. Ohrysophanus phlceas Linn. 



Specimens from Lhasa and Gyantze might be called var. 

 chinensis Felder ; but this variety is not constant. 



28. Lyc^na younghusbandi, sp. n. (Plate XXXVI. fig. 10 c? .) 

 Nearest to L.felicis Ob. (£t. Ent. si. p. 21, t. 7. f. 52 ; Leech, 



Butt. China, ii. p. 307) from Eastern Tibet. Both sexes, how- 

 ever, diflfer from that species in being dark leaden grey instead 

 of greyish brown above, and in having the marginal spots on the 

 hind wing absent or but very faintly marked ; and on the under 

 side in having the second external band of marginal spots on the 

 fore wing absent or only faintly marked. 



This may stand a good species until intermediate forms are 

 obtained, and though allied to felicis it has no other near ally 

 known to me. It was abundant at Gyantze, and was also taken 

 further south on the march from Phari. 



I name thi.-s species in recognition of the great assistance given 

 by Sir F. Younghusband to the officers of the Mission in their 

 scientific explorations. 



29. Lyc^na ORION Pall., var. 



A single specimen only from between Phari and Gyantze is 

 not separable fi'om orion, though it might be called var. orithyia 

 Griim, of which the types, from Amdo, are before me. 



30. Lyc^na semiargus Rotb. var. annulata, var. n. (Plate 

 XXXVLfigs. 12 c?, 11$.) 



Though this may be distinguished from all the numerous 

 varieties of semiargus known to me by the well-marked white 

 Ting round the central spot on the fore wing below, yet this is 

 hardly a character of sufficient importance to be specific, being 

 found as a local variation in some others of the genus. The 

 males are of the same dull blue above, but the border is darker 

 than usual in semiargus, and the under side is more silvery as in 

 sehrus. There is also a more or less well-marked series of marginal 

 black spots on both wings below as in var. hellis, the eastern form 

 of semiargus, but no orange ocelli on the hind wing below as in 

 that form. The females are dark brown above as in semiargus.
