94 Mr. A. G. Butler on Rhopalocera 



so below, much duller and more sickly-coloured on the under- 

 side, with the transverse lines of secondaries chocolate-brown ; 

 the lilacine streaks replaced by slaty grey. Expanse of wings 

 2 inches 3 lines. 



About 370 miles from Tokei. 



A. rabdia differs from A. daj)hne in structure as follows : — 

 Palpi longer; primaries more produced, their outer margin not 

 convex (more inclined to be concave), scarcely undulated. An 

 example from Ilakodadi, in the Museum, more nearly resembles 

 A. daphtie, but still differs too evidently from it to admit of 

 their being associated together. 



Colias 2)alceno, Linnaeus. 



Of this species Mr. Fenton says : — " I had great trouble in 

 capturing two couples on the side of a ban-en volcanic moun- 

 tain covered with scanty grass, low herbs, and wind-dwarfed 

 pines, at an elevation of about 7000 feet above sea-level (re- 

 gistered by a pocket aneroid)." 



Thedajaponica^ Murray. 



About 370 miles from Tokei. 



Mr. Murray need not be in the slightest degree alarmed for 

 his species ; it is perfectly distinct from T. smaragdina. We 

 have the latter from Hakodadi. 



Before passing on to Chinese species, I should wish to 

 make a few remarks upon Mr. Murray's paper, " List of 

 Japanese Butterflies," because if it be, as its author states, 

 merely preliminary, it will be well for him to have an oppor- 

 timity of weighing my opinions against his own, and, at any 

 rate, he will have the advantage of any little facts which I am 

 able to give him (or any other who may wish to study 

 Japanese butterflies) . 



Lethe diana is not only not identical with S. marginalis^ 

 Motsch., but is probably not congeneric with it ; the latter is, 

 in all probability, a MycaJesis. L. Whitelyi is perfectly 

 distinct from Lasiommata Maakiij being quite different in 

 form, colour, and marking. 



Pronophila Schrenki is not a Satyrus, but a Lethe. 



Argynms ella is = ^. anadyomene ; the A. daphnis of 

 Motschoulsky is probably A. nerippe] A. adijype is not 

 Japanese. 



It is extremely doubtful whether Araschnia burejana is A. 

 strigosa, although I have regarded them as possibly identical. 



Neptis aceris (var. eurynome) . Under this name Mr. Mur-
