are distinctly more pointed." He goes into considerable more 

 minnte detail. [Tutt remarked on this author, " Fuchs, is on the 

 whole, one too many for me," in lit.] 



In 1892 Staudinger, in the " Memoires Romanoff" (vol. vi., p, 

 206), described the hypcrantus-iorm from the Amur district of Asia, 

 as a»nireiisis, a much larger form, in which the wings are consider- 

 ably widened. In "Cat.," ed. iii., 1901, he afterwards acknowledged 

 that this was identical with the ocellatus of Butler. 



In 1895 J. W. Shipp, in the " Entomologist " (vol. xxviii., p. 17) r 

 described the form figured in 1893 by R. South (vol. xxvi., p. 281), 

 and named it lanceolata. The chief points in it are — " Upper 

 surface, hindwings with four similar ocellated lanceolate spots," 

 "in one or two instances produced to a point." "Underside, 

 forewings with two large semi-lanceolate ocellated spots," "hind- 

 wings with five lanceolate ocellated spots," etc. 



In 1896, Tutt, in his " British Butterflies ; Hedgerow Series " 

 (p. 412), introduced a form obsoleta, " with no trace of ocellated 

 spots." 



In 1908, Seitz, in " Alacrolepidoptera of the World. Palfearctia 

 Fauna" (vol. i., p. 137), described and figured the following two 

 forms of hyperajitna; (1) arctica, a small form from the highest 

 north, and (2) cenlrifera, the form with the white eye-centres, i.e., 

 small rings filled in with white dots often visible on the upperside 

 as well. 



[I have endeavoured to find out the origin of the aberrant 

 spelling, which one occasionally meets, of hyperantus as hypemnthes^ 

 but without success so far. — H.J.T.] 



In 1903 the Rev. G. Wheeler, in his " Butterflies of Switzer- 

 land " (pp. 115-116), gave the direction of the variation obtainable' 

 in hyperanthiis as follows : — 



{a) Great diminution of size, e.g., ab. minor, ab. arctica. 



(h) Loss of eye-spots, e.g., ab. arete, ab. ccEca, ab. obsoleta. 



(c) Number of eye-spots. See Stephens' " 111. Brit. Ent.," I., 60, 



(of) Arrangement of eye-spots, e.g., ab. vidua, ab. octocidata. 



(e) Shape of eye-spots, e.g., ab. lanceolata. 



(/) Presence or absence of eye-spots upper side. 



(g) Traces of transverse lines on underside, v. rarely. 



During the subsequent debate other lines of aberration were 

 instanced as follows : — 



(h) Occurrence of a band on the under side of the hindwing. 



{i) Presence of white points in the upper side eye-spots.
