regarding Delias sanaca. 845 



D. hearseyi, Butler, described from Barrackpore ! True 



habitat unknown.* 

 -D. hoylece, Butler, Sikkim. 

 D. horsfeildi, Gray, Nepal. 

 D. sanaca, Moore, Western Himalaya, but recorded by 



Mr. Moore in Cat. Lep. Mus. E. I. Co., from 



Darjeeling !t 

 D. flavalha, Marshall, Kunawar. 



[I must apologise both to Mr. de Niceville and 

 to the Society for the delay in the publication of this 

 note, which was sent to me just as I was leaving 

 England last year. As Mr. de Niceville asked me to 

 make any comment upon it which might seem useful, 

 I may now say that his views entirely concur with my 

 own as expressed in the ' Annals of Natural History,' 

 and in this Society's ' Transactions ' of last year. 



But I do not think it can be any longer doubtful that 

 whatever views may be still held as to the specific dis- 

 tinctness of D. ithiela, Butler, and D. sanaca, Moore, 

 from D. belladonna ; D. herinda, Moore, is a synonym of 

 ithiela, whilst D. hoylecs and D. hearseyi, Butler, are 

 both synonyms of horsfeildi. As I have now had 

 an opportunity of seeing a large number of belladonna 

 collected near Ichang, in China, by Mr. Pratt, which 

 are in Mr. Leech's collection, I may further add 

 that they have the broad yellow abdominal patch and 

 white inner margin on the hind wing of horsfeildi, 

 with something of the duller black and less white 

 markings of ithiela ; but they may be distinguished 

 from Himalayan forms, in common with my specimens 

 from Tsekou, in South-east Tibet, by the more elongated 

 spots on the under side. 



In this case, as in many others, the light which is 

 thrown on the question by increased numbers of speci- 

 mens from fresh localities, all goes to prove that a very 

 wide range tends to produce variation ; and that the 

 greater our knowledge of wide-ranging and variable 

 species, the greater becomes our difficulty in defining 

 the varieties. — H. J. Elwes.] 



■'' Almost certainly from Sikkim. 



•f- This is a mistake. It is the form known as horsfeildi which 

 occurs in Sikkim. — H. J. E.
