THE liUTTEKFLIES OF SWITZEKLAND 



wh. is perfect without it. It is the more curious, as the leg is a true limb, wh. 

 the wing-structures, correctly speaking, are not.] 



M. Aurinia, Rotf. (Artemis, Hh. ; Maturna, Ksp.) ; 40mm. 



F(l. pit. scabious, plantain, Sec. 

 $ larger, and with broader and lighter markings than J , 

 Dist. Char, up.s. h.w. red ante-margl. band distinctly spotted with 

 bik., the blk. nervures being v. clear and well defined. 



Log. Gen. in marshy spots, but sometimes in v. dry places, v. 

 m. and vi. ; distributed over the whole region in the lowlands and 

 often up to 4000ft., above wh. a break occurs, var. Meropc not 

 appearing below 5500ft., or thereabouts. As Fny, who speaks of it 

 as being found all over Switz., adds that he has never taken it, I 

 give a few Iocs : Veyrier, v. 17.-22; Hermance, vi. 14 (HI.) ; Caux, 

 VI. /97; Lavey, v. 27, &c. /02 ; Brig, v. 16 03, v. brt. (Tf'A.) ; Jeur- 

 Brulee, abo\e Fully, v. ab. {Far.) ; Bisbinno, vi. 3 {Mai/cr) ; Weis- 

 senburg, v. c. (77//.) ; the Jura {Fyci/) ; Mt. Barry, vi. 28, 1900, 

 nearly over (/.'/.///.) : Brunnen, swampy grd. by lake, v. 18/88, v. ab. 

 {Hiitchiiinnv) ; and, as a contrast, v. ab. on the dry N. side of 

 Charpigny (7'V.s.). 



At Digue, iv. e. /'97, v. ab., mostly var. Artciiiis, but some var. 

 Proline ialia (Tiitt). 



Directions of Var. 



[Obs. — This is a most variable sp., being rarely e.ractli/ similar in any 2 

 district;: ; and although certain forms are v. distinct, yet intermediate forms 

 exist between the type and vars., and between the vars. themselves, exc. in the 

 case of Merope, wh. is so isolated that it is doubtful whether it has not obtained 

 specific rank : (even the specimens bred by the Eev. .T. S. St. John do not 

 necessarily tell against this \iew, though they go far towards establishing the 

 phylogeny of Merop"). The different forms are rather vars. than abs., as they 

 are mostly local races, found, however, as abs. in Iocs, in wh. other forms 

 predominate.] 



(a.) size : esp. a great diminution at high 

 altitudes, forming : 



var. Merope, Pninncr : 82-36mm., col. much washed out, and blk. 



nervures much suffused. 



|Obs. — Merope varies greatly in amount of suffusion, and the depth of 

 colouring up.s.] 



Log. In more or less numbers in marshy places on nearly all 

 the high Alps from 5500ft. almost to the snowline, vii.-viii., <v/., 

 Pont de Nant, vii. 18 {III.) ; Arolla, Pas de Chevres path, vii. 13, 

 itc, 1900, rather worn (Jlkiii.) ; Riftelalp, ab. [Postanfi) ; Simplon 

 Pass, vii. 10/01 ; vii. 28/99, not c, v. dk. with yellowish wash (IT//.) ; 

 Upper Engadine, v. ab., esp. Alp Laret, nr. St. Moritz, vii. {Nic/kiI- 

 mn) ; Guarda, vii. 22-31, 1900 ; Fusio, vii. 1-12 /99 ; Pontresina, 

 vii. 1-21, 1900 ; Heuthal and Val Tuoi, vii. m. 1900, v. ab. (C7//>.) ; &c. 



Le Lautaret, viii. b. /96 {Tiitt) ; Larche {Poirell) ; Alpes Mari- 

 times (Brill.) ; Pejo, vii ./95 ; Campigho, vii. /95 ; Heiligenblut, vii.
