88 THE BUTTERFLIES OF SWITZERLAND 



from between Zermatt and the Gornerorat {(Tiienrc) : considering 

 its Piedmont haunts this is quite a likely loc, and I have myself 

 taken S specimens on the Simplon, vii. m. /Ol. 



Larche, vii. e. 1900 ; Abries, viii. m, 1900 ; Pre St. Didier, 

 summits of the Crammont and Mt. de la Saxe, vii. b. /98 (Tiitt) ; 

 Jh-enner on the Postalp, vii. 28, 1900, <? s worn, $ s fine {E.-Ihn.). 



[Obp. — " An insect v. inconspicuous on the wing, and with a ' bee-like ' 

 mghf' (h'.Jini.).] 



Directions of Yar. (a.) some specimens slightly more trans- 

 parent-looking. 



[Obs.- — Frey observes that this sp. is rich in vars. ; I have only once taken it, 

 but all that I have seen in collections are singularly constant, and all those of 

 my correspondents to whom I have addressed special enquiries on the subject 

 bear this out from their own experience.] 



M. Aurelia, XivkcH (Parthenie, Hhst. ; Athalia minor, 



Esj). : Athalia, Hh.) ; 32mm. Fd. pit. Mdainjti/niut and 

 plantain. 

 $ lighter in markings than ^ . 

 Dist. Char, small size, together with breadth of blk. markings 

 giving a chequered appearance. 



Loc. Apparently confined in Switz. to the Valais, the Grisons 

 and Tessin, mostly at low elevations, but rising in places to nearly 

 6000ft. ; local in Valais, but found in many places : Visp, on an 

 open bank about a mile along the Brig road, vi. 16 99, c. ; Ehone 

 meadows at Sion, v. 20, 1900 (il'A.); Berisal, viii. 2/97 {J I.- Urn.) ; vine-

 18/02, dk. specimens (Fis.).

Directions of Yar. (a.) lighter grd. col. and narrower blk. 



markings. 

 var. Rliaetica, h'rey. 



[Obs. — As lUuftica is sometimes spoken of as a darker form, I give the 

 original description translated from Frey's " Lepidopteren der Hchweiz," p. 30 : 

 " smaller, lighter red-brn., less dull, with narrower blk. markings, the ? not 

 rarely with v. It. brn. rows of spots."] 



Loc. Coire, v. c. {('ajUsch) ; vii. 8/01 (/'V.v.) ; occasionally among 

 the Visp specimens (H'A.).

 Yar. Britomartis, AKsinann (? Veronicjp, J torfmcistcr : ? Aphjpa,

 tribus cinnamoneis, maculisque duabus sub-albicantibus, linea nigra
