It will be noticed that- all three forms mentioned above 

 were tnken at the same locality within a week. 



It may be of interest here to publish a note on the 

 Central Asiatic forms of this genus made by M. Andre 

 Avinoff shortly before the war and left at the B.M.; it 

 should help to clear up the muddle which surrounds 

 P. inter posit a, Stand. It runs : — " Polygonia eyea (tri- 

 angulwn) is found in Europe; in the south begins, from 

 Caucasus, to get darker and gradually runs into the form of 

 Central Asia. It is not the interposita of Staudinger, as the 

 interposita is the c-album form with some character of eyea 

 (I saw the type and studied the form by the Turkestan 

 material). Grum-Grshraailo gave the name undina (Rom. 

 Mem. iv. p. 424) to the eyea of Turkestan, but he was not 

 (juite right on the distribution (all he says about Oscli and 

 ilargelan). In reality undina goes to Chitral by Bokhara 

 and flies with interposita. The series of the B.M. contain 

 both species ; eyea does not go to the south. Interposita is 

 darker in Chitral, Goorais, Thundiani (coynnta), and brighter 

 and less dark iu the South Himalayas (Nepal, Sikkim to 

 Ta-Tsien-Lu), where it is aynicula (tibetanus, Elwes). Inter- 

 posita is very near to c-album, but it may be a distint species." 



From this, the series in the B.M., and indeed from 

 Staudinger's original description (Stett. Ent. Zeit. 1881, 

 p, 286), it is evident that interposita has nothing to do with 

 eyea, although almost invariably associated Avith it by 

 authors. Staudinger's description certainly is discursive to 

 a degree, but it is obvious he regarded interposita as a closer 

 ally of c-album than of eyea. What has hitherto been 

 generally known as interposita must in future go by the 

 name undina, Gr.-Gr. 



The position in the Himalayas seems to be that there are 

 three species, represented in the B.M. as follows : — 



1. P. egea undina, Gr.-Gr., from Chitral and Hunza. 



2. P. c-albiwi cognata, Moove, „ Tliimdiana,Kulu, Xandar, 



Simla, aud Chumpiir. 



3. P. interposita interposita, Staud., „ Chitral, Ladakli, Kvlaug, 



Kulu, Goorais, Paugi, 

 Dugi, Goolmurg, and 

 Gurwhal. 

 3a. P. interposita agnicitla,lslooi'Q „ Nepal, Sikkim, Tibet to 

 {tibetanus, Elwes). Ta-Tsien-Lu. 



It may be as well here to correct a further error, for
