14 BRITISH BUTTERFLIES. 



the $ s from Valais, Savoy, and the district around Geneva, may have the 

 forewings almost unicolorous, or marked with ill-defined whitish or 

 fulvous marginal lunules, lacking towards apex, and larger at the 

 inner margin than towards the costa, the concavity of these lunules 

 turned outwards, so that they surround a series of indistinct, but 

 traceable marginal spots ; the hind wings with the orange lunules 

 more or less well-defined, in front of a series of seven black marginal 

 dots, the two hindmost in the same space, the foremost least marked 

 and often absent ; in one 2 from Arolla, only traces of spots 5, G, and 

 7 are present, the forewings being quite unicolorous. Blachier records 

 a $ from Thoiry, with bright orange-red lunules on the forewings 

 and hindwings so strongly marked that, on the hind wings, they almost 

 form an antemarginal orange-red band' (ab. aurantia), sometimes 

 they are pale yellow ( = ab. flavescens, n. ab.) ; ?s with the black 

 chevrons of the orange marginal lunules themselves surmounted 

 by white (ab. alboliuudata) are recorded from Versoix, Mornex, etc. ; 

 Wheeler has a $ from the second Refuge on the Simplon Pass with 

 an almostcontinuous orange bandon the hindwings, and a broken orange 

 band continued almost to the apex of the forewings (ab. aurantia), and 

 another from Aigle in which a narrower orange band is almost unbroken 

 on the hmdwing, though the orange is barely visible on the forewing(ab. 

 per aurantia). He also notes that, in his Italian specimens, the orange 

 chevrons, though generally indicated on thehindwing, are as anile narrow 

 and inconspicuous, and do not extend to theforewing (ab. subaurantia); 

 there is, however, one among his specimens from Assisi in which they are 

 rather strongly marked on the hinclwing, while they are also visible 

 on the forewing in one specimen from Fiesole, and in the only 

 example (a very large one) taken by him at Monte Orvieto. The 

 following is a clumsy attempt to group the various forms of the ? s 

 of this species without attempting to differentiate the difference 

 in ground colour : — 



1 . — With no orange lunules = ab. unicolor, n. ab. 



2 . — With indistinct marginal spots faintly edged with greyish = ab. suboceUata, 



n. ab. 



3 . — With orange lunules on hindwings only = ab. subaurantia, n. ab. 



4 . — With orange lunules on hindwings faint on forewings = ab. peraurantia, n. ab. 



5 . — With orange lunules on all wings = ab. aurantia, Tutt. 



6 . — With orange lunules of hindwings surmounted by white secondary lunules = 



ab. subalbolumdata, n. ab. 



7 . — With orange lunules of both wings surrounded by white secondary lunules = 



ab. alboliinulata, n. ab. 

 la. — As in 1, but basal area (not reaching discoidal) of wings scaled with blue = 



ab. basicaeruleata, n. ab. 

 2a. — As in 2, but basal area of wings scaled with blue = ab. caeruleosuboceUata, 



n. al). 

 3a. — As in 3, but basal area of wings scaled with blue = ab. caeruUosubaurantia^ 



n. ab. 

 4a. — As in 4, but basal area of wings scaled with blue = ab. caeruleoper aurantia, 



n. ab. 

 5a. — As in 5, but basal area of wings scaled with blue=ab. semiaurantia, Tutt. 

 (5a. — As in 6, but basal areas of wings scaled with blue — ab. caeruleo8ubalbolunU' 



lata, n. ab. 

 la. — As in 7, but basal areas of wings scaled with blue = ab. i'acruhoalholunulata, 



n. ab. 

 l/>. — As in 1, but with forewings blue-BCaled basally and hindwings sealed with blue 



(usually interneurallv) to or almost to marginal area — ab. tubradiosa, n. ab. 

 2/;. — As in 2, bat with forewings blue-scaled basally and hindwings scaled with 



blue (usually inlerneurally) to or almost to marginal area -ab. radiosub- 



ocellata, n. ab.
