"356 BRITISH BUTTERFLIES. 



by Mosley (Nat. Journ., 1896, pi. iii., fig. 24). Walker notes (Ent. Mo. 

 Mag., xliii., p. 133) that, in the " Dale coll.," are several examples 

 with the oceili of the hindwings beneath, except the discoidal lunule, 

 •obsolete, or nearly so. These, of course, are cinnus, Staudinger, but 

 not cinnus, Hb. Eowland-Brown captured at Digne a $ of this form; 

 the forewings beneath with the basal spots wanting and the spots of 

 the submedian row small, the discoidal spot, however, large ; whilst the 

 hindwings have no basal or submedian spots only the discoidal 

 spot. Hall notes (Proc. Sth. Land. Ent. Soc.) a $ from Folkestone, 

 with the left hindwing beneath, of the form cinnus, Staud., the 

 ■other wings normally spotted. 



A. ab. parvipuncta, n. ab. Adonis var. e, Stphs., " Illus. Haust.," L, p. 90 

 <(1828). — The spots on the underside small. 



Small-spotted examples are, in our experience, much rarer than 

 heavily- spotted ones. Reverdin observes (in litt.) that he has a 2 , 

 taken near Geneva, in which the submedian spots are very small. 



[x. ab. crassipuncta, Courv., "Mitt. Schw. Ent. Geseli.," xi., pt. 1, p. 19 

 <1903). Bellargus, Esp., " Schmett. Eur.," pi. lv. (contd. v.), figs. 4,6(1778); 

 Bergstr., "Nom.," iii., pi. liii., fig. 6(1779). — The curved rows of spots, the 

 'basal spots and the discoidal lunules, strikingly enlarged on all the wings 

 <(Courvoisier). 



v. ab. albo-ocellata , n. ab. Cinnus, Tult, " Brit. Butts.," p. 171 (1896). 

 €innides, Wheeler, " Butts. Switz.," p. 33 (1903). — A form with the spots on the 

 undersides of the wings white, and without dark pupils (Tutt). 



In rare cases, the spots of the submedian transverse row are not 

 ocellated, but form small white dots without black centres. This 

 form of aberration appears to be more frequent in the hind- than in 

 the forewings. Hanbury notes (Ent. Rec, iv., p. 19) the capture of 

 an example in Kent, in 1892, combining ab. antico-obsoleta and ab. 

 albo-ocellata, and describes it as having the underside with only one 

 large spot in the centre of each fore wing, whilst the spots on the hind- 

 wings are entirely replaced by suffused white patches. 



£. ab. nigro-ocellata, n. ab. — The ordinary ocellated spots on the underside 

 ■without white margins, only the black kernels being left. 



This is a very rare form, found occasionally in examples with the 

 ground colour of the underside exceptionally pale ; the marginal spots 

 also are usually more or less obsolete in such specimens. 



o. ab. addenda, n. ab. Bellargus, Esp., " Schmett. Eur.," pi. lv. (contd. v.), 

 fig. 3 (1778).— The underside presenting additional spots in usually unocellated 

 areas. 



Specimens with additional spots in usually unocellated areas, are 

 not at all uncommon in collections, and we have already noted that 

 the striate specimen figured by Oberthur (Etudes, xx., pi. iii., fig. 28) 

 has had its streaks formed by the union of such additional spots into 

 linear form. The most common position for the development of these 

 spots is (1) between the outside of the discoidal and spots 2 and 3 of 

 the submedian series, and (2) between the inside of the discoidal and 

 the basal spots, although other positions are sometimes to be noticed, 

 e.g., rarely under the discoidal between the lower basal and lower sub- 

 median spots, not as extensions of these, as in ab. semiarcnata, but as 

 small ringed spots of normal appearance, etc. The additional spots 

 are much more frequent on the forewings than on the hindwings, and, 

 •as noted above, the most common (but not only) position is between
