Several examples, coll. Pryer. I took a specimen at Gensan in 

 June. 



Three of the specimens in Fryer's series of this species were 

 labelled subvaria, but this was most certainly an error. B. subvaria 

 does not appear to occur in Japan.

Walker's type of this species was from N. China. There were no 

 specimens of this species in Fryer's collection, neither did I meet 

 with it in any part of Japan. Specimens labelled subvaria were in 

 Fryer's collection, but these are metalkana, Led. I received a 

 fine series of R. subvaria from a native collector at Ningpo, which 

 agree perfectly with Mr. Butler's figure and description of that 

 species. 



There are no examples of this species from Japan in the National 

 Collection, South Kensington.

 p. 396(1877); 111. Typ. Lep. Het.pt. ii. p. 5, pi. xxiii. fig. 2 (1878). 



An exceedingly variable species occurring throughout Japan, I 

 am not satisfied that R. simplicior, Butl. (Trans. Eiit. Soc. 1881, 

 p. 6), is anything more than a var. of this species.
