46 BRITISH LEPIDOPTERA. 



£. Right wings and antenna ? , left 3 . Bred by Hettlinger [Hettlinger, 

 Rozier. Journ. Phys., pi. xxvi., pp. 268 — 271 (1785)]. 



i}. 3 left, $ right. Incompletely gynandromorphous. Body and right side ? , 

 left 3 • Hindwings beneath brown with yellow outer margin. Forewings ochre- 

 yellow ( ¥ ). Left antenna scarcely stronger, both with chestnut-brown pectinations. 

 In Vienna Museum, from Mazzola's collection {vide Ochsenheimer, Die Schmett., iv., 

 p. 190). 



9. Abdomen, thorax and three wings apparently ? , the fourth wing, both in colour 

 and size, a mixture of both sexes ; antennae with pectinations shorter than in 3 , yet 

 much longer than in ? ; abdomen without eggs, yet in life as stout as an ordinary ? , 

 later it voided a thick dark brown fluid, and became shrivelled. Bred 1855 by 

 Dorfmeister (Stett. Ent. Zeit., 1868, p. 183 ; Mitt. Ver. Steierm., iv., p. 69J. 



1. Incompletely gynandromorphous. Abdomen filled with eggs. One antenna 

 3 , the other ? . Bred by Dorfmeister, 1856 (Stett. Ent. Zeit., loc. cit. ; Mitt. 

 Ver, Steierm., iv., p. 69). 



k. Incompletely gynandromorphous. 3 with ? colouring ; body and upper 

 side of all the wings fine ochre-yellow, without transverse band, only towards the 

 hind margin the chestnut -brown ground-colour shines slightly through, although 

 absolutely covered by yellow hairs. The fringes entirely of a pure bright yellow. 

 The central spot of the forewings, which is normally dark-margined, is yellowish- 

 white, without bordering. Underside uniform ochre-colour, without band. Antennas 

 yellow, with chestnut-brown " lamellae " (pectinations). In the Nickerl collection, 

 Prague (Nickerl, Verh. zool.-bot. Ges. Wien., 1872, p. 732). 



X. A female, the reproductive organs, however, being but imperfectly de- 

 veloped. Bred. Differing from its sisters of the same brood, it failed to attract 

 any males by 'sembling,' although favourably exposed for that purpose" (Griffiths, 

 Science Gossip, 1875, p. 270, fig. 167). 



Bacot and Prout agree that the figure looks like a slightly 

 crippled typical ? , with central area of forewings and basal two-thirds 

 of hindwings slightly darkened. 



fi. Gynandromorphous, so that left half is 3 , right ? . Bred 1884, Vienna. 

 In the possession of Joseph Muller, Vienna (Wachtl, Wien. Ent. Zeit., 1884, p. 

 290, tab. v., fig. 3). 



v. Left wings, left antenna, thorax and abdomen ? ; right antenna and 

 wings 3 . On the right forewing stripes of ? colouring, also in hind area of 

 hindwing ; abdomen externally entirely ? , but when anatomically examined the 

 sexual glands were found to be completely arrested ; the excretory passages and 

 external copulatory parts also purely ?. "Kittdriisen" and "appendix gland" 

 of the receptaculum seminis are wanting. Bred 1883 from larva (Bertkau, Archil* 

 Naturg., 1889, p. 77 ; Sitzber. d. Niederrh. Ges., 1888, p. 67). 



£. A genuine mixture of the two sexes, the ? form, however, predominat- 

 ing; antennae neither decidedly 3 nor ? ; the right wings show a regular mixing 

 of the sexes; the left wings are female, with only a few 3 -coloured areas; the 

 abdomen, in form, size, and colour, ? , containing eggs ; the external organs 

 female, yet the anal aperture very different from that of the ordinary ? . In the 

 museum at Geneva fc.f., Guenee, Mem. Soc. Phys. et Hist. Nat. Geneve, xxi., 

 pp. 418 — 422, fig. 8; Mem. Boston Soc. Nat. Hist., ii., 1871 78, pp. 411- 412). 



0. Incompletely mixed. What is 3 on the upperside of the wings is ? on 

 the underside, and vice versa. In coll. Bornemann. Magdeburg (<"./"., Ribbe, 

 Deutsch. Ent. Zeits., 1889, p. 186, pi. iv., fig. 5). 



7r. Male with very much yellow dusting, so that it resembles a light ? . In 

 possession of Hcrr Bernard, Dantzic. Bernard in litt. (Schultz, Illus. Woch. 

 fiXr Ent., ii., p. 414). 



p. A ? , with the absolutely dark-brown colour of the 3 . Caught at 

 Dantzic. In possession oi the above-named (Schultz, loc. cit.). 



q. 3, which has exactly the colour of the ?. In coll. Gleissner, Berlin [<"./*., 

 Perl. Ent. Zeit.) 1888, Sitzungsberichte, p. (5)]. 



t. Incompletely gynandromorphous. In shape of wings 3 , in colour ? on 

 upperside. On underside 3 and 9 colouring irregularly mingled. Form of 

 body, as also antennae, neither 3 nor ? , but intermediate ; antenna] pectinations 

 about one-half shorter than those of the 3 . Bred at Freiburg (Silesia). In coll. 

 Wiskott, Breslau (Wiskott, Festschr. Ver. Schles. Ins., 1897, p. 119). 



v. Incompletely gynandromorphous. Antennae, form of body and wings 

 ueither definitely cf nor % ; rather intermediate between the two. Colour on
