kaido (Yesso) io safety. In looking them over I was able to see 

 some varieties and some species nev? to me, some of which I have 

 described, and the others I have transmitted to you. 



" Mr. Janson sent me a copy of the ' Cistula Entomologica ' for 

 June 30th, 1878, containing your remarks on, and descriptions of 

 some Japanese Rhopalocera sent home by me.

" Argynnis rahdia (No. 79). 



" I have a specimen of this measuring 2" 8'". 



" Melitcea niphona (No. 84). 



"The ?ize of this species varies considerably. The smallest I have 

 measures 1" 3'", while tiie largest is 1" 11'" in expanse. 



" Melita'a scotosia (No. 83.) 



"Specimens caught in jNlay, at Koganenohara, 18 miles east of

" Lyccena argia (No. 103 a). 



'• I have examined all mj' specimens of this, and am obliged to

 and L. argia than between the latter and L, alope. 



" Chrysophaitus phfceas (99) and Gonepteryx rhamni (12). 

 " I find that these came from an old collection of English insects 

 in Japan \ 



" Theclu orientalis (No. 98 b). 



" This varies slightly from the specimens taken southwards : 

 •Bandai' is the name of a mountain on the north side of lu.iwasiiiro 

 lake in Iwashira. The Japanese call all Butterflies and Moihs 

 ' Cho,' the only exceptions being some local names for Fapilio

" Pamj)hilajanso7iis (No. 125). 



" 2 • 'The additional white spot between the first and second of 

 the oblique discal series ' present also above."' 



" Owing to the wildness of Hokkaido, I was obliged to keep to
