136 THE BUTTERFLIES OF SWITZERLAND 



vii. m., &c. (Norris); Trafoi, scarce (Fretj) ; Croda di Lago, viii. 9- 

 18/95 ; Sorapiss, viii. 10/95 (Ttitt). 



Directions of Yar. (a.) size and number of eye-spots, 

 (b.) extent of wh. band un.s. h.w. 

 (c.) conspicuousness of It. band containing 



eye-spots, un.s. h.w. 

 (d.) breadth of red-brn. band up.s. esp. h.w. 

 The diminution of all these characters, exc. sometimes the 3rd, 

 culminates in : 

 Yar. Adyte, Hb. .- the small mtn. form, in wh. the eye-spots are 

 often unpupilled up.s. on f.w. ; always exc. at anal on h.w. 



Log. Gen. distributed over the higher alps, but not, as a rule, 

 so c. as FAiriialc, vii. -viii. 



[Obs. — The confusion existing with regard to these 2 sp. make Iocs, unreliable 

 but both are widely distributed, and gen. occur together.] 



E. ^thiops, Eq>. (Medea, Hh. ; Blandina, Fahr.) ; 



44mm. Fd. pit. Pua annua, IktctnUs f/louwrata. Ai/mtii^ 

 canina. 

 $ lighter than <? , esp. un.s. ; band up.s, f.w. red-brn. in J , 

 or.-brn. in J . 

 Dist. Char, broad bands un.s. h.w. in connection Avith conspicu- 

 ous eye-spots up.s. ; differs also from Pnmoc in having chestnut 

 band un.s. f.w. well defined interiorly. 



Loc. Probably the commonest and most widely spread Erchia, 

 both in latitude and altitude ; vii. e.-ix. m. Throughout the region, 

 exc. possibly the 8. French Alps. It is reported as c. from Thorenc 

 and Taulanne by Millnrc, and also from St. Martin Vesubie ; and 

 though some doubts have been expressed on the subject, it seems 

 unlikely to be incorrect, esp. as it is certainly to be taken on the E. 

 slopes of the 8. Alps ; Certosa di Pesio, viii. /92 (A'o/t/.s), 



Directions of Yar. (a.) size : 38mm. (Jura), 50mm. (Aigle). 



(b.) size, distinctness, and number of eye- 

 spots. The form of the 3- in wh. the 

 band up.s. h.w. becomes obsolete is 

 called : 

 ab. Obsoleta, Tutt. The other forms are unnamed. They are : 

 (J , up.s. f.w. 2-5, gen. 3 or 4 ; h.w. 0-5, gen. 3 ; un.s. f.w. 3-5, 

 gen. 3 ; h.w. 2-5, gen. 3 ; 5 up.s. f.w. 3-G, gen. 3 or 4 ; h.w. 

 3-61 , gen. 3 or 4 ; un.s. f.w. 3-5, gen. 3 ; h.w. 3-5, gen. 3 or 4. 

 The spots un.s. h.w. are often v. indistinct. 

 ab. Insequalis, Moudci/ : in wh. the number of spots on right and 

 left ws. is different. 



t Note. In the only specimen I possess with G spots up.s. h.w. the top spot 

 is red-brn., wh.-pupilled, but without any blk. ring. It was taken at Aigle.
