354 BRITISH BUTTERFLIES. 



analogous aberration in his fig. 248." This last figure is referred to 

 by Herrich-Schaffer, who notes (Sys. Bearb., i., p. 121) that Hiibner's 

 figs. 645-6 represent a rarely-occurring aberration without ocellated 

 spots on the underside, and that he has a similar one in which the 

 marginal spots are almost without red (fig. 248). Hiibner's figure 

 (Eur. Schmett., pi. cxxvii., figs. 645-6) here referred to is that of a $ , 

 the underside of the fore- and hindwings brown, with normal marginal 

 orange lunules, but the submedian and basal, spots absent, the dis- 

 coidals only present in fore- and hindwings. Curtis records (Brit. Ent., 

 fo. 6) a similar aberration, received from Leplastrier (Dover), and Walker 

 (Ent. Mo. Mag., xl., p. 189) notes the same specimen as being now in 

 the "Curtis coll.," at Melbourne, and labelled " Dorylas, Hiibn. (?)." 

 Adkin records (Proc. Sth. Bond. Ent. Soc., 1888, p. 71 and p. 165) two 

 similar $ s from Folkestone, the second figured (op. tit., pi. i., fig. 1); 

 Dennis exhibited (op. cit., 1892, p. 51) another similar example, and 

 Sladen records (Ent., xxx., p. 81) yet another, a 2 taken at Winsley, 

 in May, 1896). Gillmer rightly notes (111. Zeits. fur Ent., v., p. 52) that 

 " specimens, transitional between the type and the most extreme form 

 of obsoleta, are frequent, sometimes with the spots more, sometimes 

 less, expressed, so that," he adds, " it is undesirable to separate them 

 under a distinct name as Tutt has done in obsoleta, since the disappear- 

 ance of the spots is not constant, but varies," etc. This, of course, is 

 just what we did not do, we did not separate them under the name 

 obsoleta, but united them under the name obsoleta, our description of 

 which included the extreme form (see supra). If, as Gillmer says, it 

 is undesirable to apply a name to the transitional forms, it still leaves 

 the name obsoleta free for the well-known extreme form, and the 

 description of krodeli, a name created by Gillmer for this Extreme 

 form, being included in the diagnosis of obsoleta, krodeli unfortunately 

 becomes a synonym thereof. As shown by our original description, 

 we particularly noticed " the very striking character of the extreme 

 form of obsoleta, in which all the spots are absent except the discoidals," 

 and, if any of the obsoletely marked forms want separating, it appears 

 to be the transitional ones. The wholly obsolete examples, described 

 and figured (Zeits. fur Ent., v., pp. 51-52, pi. i., figs. 6-9, 1900( as the 

 type of krodeli, came from the Tyrol — Bozen ($ ) and Kufstein ( $ ). 

 Verity notes (in litt.) the capture of no fewer than fifteen examples 

 of this aberration in one week in the autumn of 1908, in the pine- 

 woods of the Tuscan coast, with none of the ordinary ocellated spots 

 on the underside of any of the wings. Other obsolete forms are 

 recorded (under the name of cinnus) from the Alpes-Maritimes (Bromi- 

 low), Eure — Pont de l'Arche (Dupont), PjTenees-Orientales — Bois 

 del Pinats, le Vernet (Rondou teste Oberthiir) ; Girard records (Ami. Soc. 

 Ent. France, ser. 4, v., pp. 111-114, pi. ii., figs. 4-5) two examples (1) a 2 

 in the coll. Fallou, captured in the Bois de Boulogne, in August, 1864; 

 (2) a $ in the coll. Goossens. Fallou notes (op. cit., p. 1.) a precisely 

 similar $ , taken at Montrouge on the fortifications of Paris, 



ocellated spots on the fore- and hindwings, refers also to the figures of 

 Engramelle and Herrich-Schaffer without any of the dots of the submedian 

 row on fore- and hindwings, and then strangely illustrates the obsolete form, not 

 by an example that is subtus-impunctata, but by one that shows a strange com- 

 bination of impunctate, obsolete and striate conditions, no doubt because of its 

 bizarre aberrational form. All his statements, however, refer to real imyiuictata.
