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. rahdia differs from A. da2)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 Hakodadi, in the Museum, more nearly resembles 

 A. daphne J but still differs too evidently from it to admit of 

 their being associated together. 



Colias palceno^ Linngeus. 



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

 capturing two couples on the side of a barren 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)." 



Theclajaponicay Murray. 



About 370 miles from Tokei. 



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

 his species ; it is perfectly distinct from 21 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- 

 tunity 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. marginalise 

 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 Schr&nki is not a SatyruSj but a Lethe. 



Argynnis ella is = -4. anadyomene ; the A. daphnis of 

 Motschoulsky is probably A. nerip'pe ; A. adippe is not 

 Japanese. 



It is extremely doubtful whether Araschiiia hurejana is A. 

 strigosa, although I have regarded them as possibly identical. 



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