Log. Scarce : La Batiaz (far.); Pfynwald, 1 5 , vii. /DD (117*.). 



Olgiate, viii. /98, with whole up.s. rich cream-col. (J//.s.s Ftn.) ; 

 Alpes Maritimes [Brii).). [The small local race on the DolomiteS; 

 vii. m., with lighter, yellower, f.w. (/.'.- /i*/i.), should probably be 

 referred to this var.] 



[Obs. — A V. curious and beiiutiful ab. was taken close to the Hotel at St. 

 Nicholas, vii. 23, 1900, by Mr. Buckniaster : up.s. f.w. gid. col. yell, brn., with 

 border of blk. wedges, and ante-niargl. line of blk. dots, much blk. at base, 

 extending along two-fifths of costa, and one-third of inn. marg., containing 2 

 yell, spots in the upper and 2 in the lower part : h.w. deeper in col. with border 

 of blk. wedges, cl. line of blk. dashes, and large blk. blotch fiom nr. base, 

 following but not touching inn. marg. ; un.s. f.w. few and small blk. spots: 

 h.w. pale yell, with ante-margl. line of short blk. dashes, base or. edged with 

 blk., rather broadly internally, narrowly externally ; out. marg. f. and h.w. 

 un.s. dashed with blk.] 



The 3rd group consists of those sp. in wh. the It. cl. band un.s. 

 h.w. is preceded exteriorly by a band usually containing at its out. 

 edge a row, or part of a row of or. -brn. or yell. -brn. crescentic spots, 

 and at its inn. edge a succession of narrow mottled spots, wh. are 

 often more or less repeated at the basal edge of cl. It. band : grd. 

 col. up.s. nearly unicolorous, though the lighter bands are sometimes 

 clearly indicated, esp. in I'art/iou'e 5 . The sp. of this group are 

 by far the most diffcult to determine, though by no means so diffi- 

 cult as is usually supposed, if a number of specimens can be com- 

 pared, exc. in the case of certain extreme abs. 



Intermediate between the 2nd and 3rd groups is :

 mark nr. inn. marg.
