CONTRIBimdNS TO THE FAUNA OF THE DAUPHINK ALl'S. 257 



the anal angle ; these, in turn, increase until a series of whitish 

 blotches, stretches across the wing within the ocellatecl spots, and these, 

 again, give place to a white band enclosing them. In this extreme 

 form they show, save for their larger size, no character to distinguish 

 them from C. satiinon, typical forms of which occur with this 

 remarkable race of C. iphu. My series leaves no doubt whatever 

 that satyriun is a form of the latter species, or that the two species 

 here assume such similar forms that they present no character which 

 renders them separable, either on the upper or underside, for, if we sort 

 out those with a white transverse band on the underside of the hind- 

 wings as C. mtiirion, and leave the remainder as C. iphis, we should 

 separate two specimens that I found /;/ copula, of which the male 

 would go to mtijriun and the female to qihis. One of the most sati/rion- 

 like $ specimens that I captured is identical on the upper side with 

 Hiibner's figure (250) of ? iphis. Another satyn<»i-\ike 2 on the 

 upper side has two indistinct ocellated spots on the upper side of the 

 hind-wings. The underside of this specimen is peculiarly ijiJu's, and it 

 comes, perhaps, nearer to the specimens of iphis in the British 

 Museum collection than any others I have taken. A few^ female 

 specimens have a washed-out appearance. This form is the mandanc 

 of Kirby. The males vary in tint on the upper side from a warm 

 fulvous hue to a dirty fuliginous brown, with every intermediate shade. 

 The worn male specimens are particularly dingy looking. The orange 

 marginal line is quite absent in some male specimens, in others it 

 forms a very distinct and conspicuous mark near the anal angle of the 

 hind-wing. The upper side of the female extends from a form with 

 entirely bright tawny fore-wings, with an orange marginal line, to a form 

 with a dark outer margin (more than one-eighth of an inch in expanse), 

 through which the orange marginal line runs. These latter graduate 

 to male forms in which the grey suffusion is more or less spread over the 

 fore- wings, and the specimens then become typical sati/rion. The 

 hind-wings of the females are all more or less fuliginous brown, with 

 a fulvous tinge in the centre and towards the base. So unlike the 

 typical forms of this species as figured by Hiibner (figs. 249-251; are 

 the Lautaret specimens that I propose calling this race var. dauphini. 

 The race is composed of specimens which may be classified as : — 

 (1) ab. nb.tnlrta. Without any ocellated spots on the underside of fore 

 and hind-wings. (2). Ab. inteniwdia. With a more or less complete 

 series of ocellated spots on the underside of the hind- wings (and 

 sometimes a trace of a single one on fore-wings), but the white band 

 only represented by two or three broken blotches. (3). Ab. virfjata. 

 With a complete white band crossing the underside of the hind-wings, 

 and containing the ocellated spots towards its outer margin. I may 

 here mention that this latter differs from Hiibner's type (fig. 251), inas- 

 much as in the latter the white band is complete, but does not reach 

 to, and therefore does not include, the ocellated spots. The var. 

 daupJiini may be best separated as a whole from the ordinary typical 

 German form (evidently the one figured by Hiibner) by the almost entire 

 absence, in both sexes, of ocellated spots on the upper side of the fore- 

 and hind-wings. Coenonynipha satijriun. — I have already stated that I 

 believe, and that my series proves, 6'. sati/riaji to be a form of C. ipliis, 

 or, if the two be distinct species, that the latter assumes a form with a 

 well defined white band, containing a series of ocellated spots on the
