398 MR. J. H. LEECH ON THE BUTTERFLIES [May 3, 



described by me. So far as can be ascertained, without examining 

 tlie dentition, the Snake is a Lamprophis, a member of the Lyco- 

 dontine group of the Colubroids. I am unable to refer it to any 

 described species, and have much pleasure in naming it in honour of 

 its discoverer. 



Lamprophis fiski, sp. n. (Plate XXXIV.) 



Twenty-three series of scales ; vertebrals not enlarged ; eight upper 

 labials, fourth and fifth entering the eye ; two postoculars ; loreal a 

 little longer than deep ; prsefrontals in contact with supraoculars ; 

 frontal broad ; tail short, ending very obtusely. Lemon-yellow on 

 the five median rows of scales, with large blackish-brown spots 

 forming a single series anteriorlj% a double alternating series poste- 

 riorly ; head lemon-yellow above, with symmetrical blackish-brown 

 markings, viz. an ohlique band on each side of the occiput, a horse- 

 shoe-shaped band passing through the eyes and across the snout, 

 and a bar across the frontal ; lateral scales of body and tail dark 

 brown in the centre and yellowish white on the borders ; upper lip 

 and lower surfaces white. Iris dark bronze. 



The specimen, which measures 315 millim., was sent to Mr. Fisk 

 from Touw's River by Mr. G. Atherstone.

[Eeceived April 16, 1887.] 

 (Plates XXXV. & XXXVI.) 



The Lepidopterous fauna of Japan contains so many species common 

 to Corea, that I have deemed it advisable in this paper to unite 

 them. 



The accompanying tables show how nearly allied the faunas of the 

 three districts, viz. Japan (the main and two southern islands), Yesso, 

 and Corea, are. My work has been greatly facilitated through the 

 kindness of Mr. Elwes, Mr. Butler, and Mr. Kirby. I have also to 

 thank Mr. Fenton for the permission to view his collection, and 

 Mr. H. Pryer, of Yokohama, for much kindness and many valuable 

 hints during my stay in Japan. 



The following is a summary of my results : — 



Japan (main and two southern islands) 123 species. 



Yesso or Hokaido 89 ,, 



Corea 91 „ 



Species (f) which occur in Japan and Amurland, 



and which may be expected to occur in Corea 22 ,, 

 Common to Japan and Yesso 131 „
