 " Schmett. Schles.," pi. xxi., fig. 69e (1842). — With discoidal spots edged with 

 white, often with streaks of blue on hind wings (Tutt). 



This is a not uncommon form of the 2 in which the discoidal 

 spots of the forewings are ringed with white; more rarely the discoidal 

 of the hindwings are also similarly ringed, or are replaced by tiny 

 white spots, so that all four discoidals stand out conspicuously ( = ab. 

 albipuncta). In its further development the rings and spots may 

 be blue (caeruleocincta and caeruleopuncta). Stephens' definition is: 

 " Above brown with a blue disc, and a whitish discoidal dot with a 

 black pupil ; beneath, the posterior wings have a discoidal white- 

 cinctured crescent with a waved band of seven undulated spots 

 towards the hinder margin." Meyer-Diir, in 1852, noted examples 

 from Alpbach near Meynngen, with a white discoidal spot on the 

 upperside of each wing (albipuncta). Keynes notes (Ent. Rec, xviii., 

 p. 240) the capture of a specimen August 4th, 1905, in the Pfynwald, 

 with the discoidals of the forewings conspicuously ringed with white, 

 and a conspicuous white spot on the upperside of the hmdwings. 

 Trautmann records (Int. Ent. Zeits. Gub., ii.,p. 162) the capture, at Jena, 

 of specimens with the spots more or less broadly surrounded by white; 

 and one had a complete row of blue lunules on the hindwings (ab. 

 subcaeruleolunulata) . Bartel notes the capture of an example of albicincta 

 near St. Moritz, July 24th, 1904. Eeverdin notes (in litt.) it as not 

 uncommon in the Geneva district, and Blachier writes that he has an 

 example in which all four discoidals are ringed with white ( = ab. 

 albipuncta). South exhibited (Proc. Sth. Lond. Ent. Soc, 1902, 

 p. 105) a 2 with four white discoidal spots and a white submarginal 

 lunulate line on all wings, taken in Wiltshire ( = albipuncta- 

 lunulata). Neustadt and Kornatzki (Schmett. ScJdesiens), judging from 

 their illustration of the $ coridon, seem to have regarded this (albi- 

 cincta) as the usual form of the 2 . Aigner-Abafi reports it from 

 Budapest and Isaszegh. [See also antea, p. 12.] 



|8. ab. aurantia, Tutt, "Brit. Butts.," p. 167 (1896); Grover, "Ent. Bee," 

 ix., p. 312 (1897); Wheel., " Butts. Switz.," p. 31(1903); Bartel, "Ent. Zeits. 

 Guben," xviii., p. 115 (1904); Seitz, " Gross-Schmett.," L, p. 315 (1909); Kebel, 

 " Berge's Schmett.," 9th ed., p. 72 (1909). Aurantiaca, Lamb., " Pap. Belg.," p. 

 240 (1902); Haverk., " Ann. Soc. Ent. Belg.," 1., p. 156 (1906); Lamb., " Cat. Lep. 

 Belg.," p. 427 (1907). Aurinnta, Grund, " Int. Ent. Zeits. Gub.," p. 87 (1908).— 

 Dull blackish-brown, with distinct marginal orange spots edged internally with 

 paler (Tutt). 



Usually the ? s of this species are poorly marked with orange on 

 both fore- and hindwings, but, in many examples, the colour is intensi- 

 fied especially on the hindwings, and may be faintly edged again with 

 pale greyish internally. Those $ s with strongly marked orange spots 

 on all the wings are our ab. aurayitia. The pale edging in its extreme 

 form, consists of a series of pure white lunules, and is then often 

 continued in a modified form on the forewings ( — albolunulata). 

 Aigner-Abafi reports the aurantia form from Budapest and Isaszegh.
