466 BRITISH LEPIDOPTERA. 



at all in contrast with the ground colour ; the whole wing more ex- 

 panded than the right. The red-brown basal spot on the left 2 side 

 is only about f the size _of that on the right. On the underside the left pair 

 of wings distinctly differs in coloration from the right ; the <? wing is here distinctly 

 marked, the ? almost without markings. Right antenna s , left ? . Palpus of 

 the J side dark brown, longer-haired ; palpus of the ? side paler-coloured, less 

 long-haired. Abdomen with distinct longitudinal ridge, which divides the body into 

 two halves, of which the right is considerably more voluminous and more darkly 

 coloured than the left. The anal tuft of the s as well as the genital aperture of the 

 ? is distinctly discernible. This gynandromorph was bred in 1896 by Krieghoff at 

 Langewiesen in Thuringia (Schultz, Soc. Ent. , xiii., p. 1 ; ///. Zeits.fii.rEnt., iii , p. 136). 



6". Left side 3 , right 2 . Left antenna s , right ? . Palpi without distinct 

 difference as regards coloration. The same may be said of the legs. Right pair of 

 wings larger, ? , left smaller, <? . Left forewing dark brown, with sharp markings 

 and strongly contrasting central area, less scalloped than the right, which passes 

 more into the grey coloration and allows of less marked contrast in the central area ; 

 however, the character of the markings is more distinctly pronounced here than on 

 the 2 forewing of the example above described. Right hind wing with smaller 

 red-brown basal spot ; left hindwing normal <$ . Body without any sort of 

 dividing ridge of hair above or below 7 . 2 genital aperture visible, and on the right 

 side of it a <? tuft of hair. This example was bred from the same brood as the above, 

 together with about 60 normal specimens, by Krieghoff floe. cit.J.

 (Schultz, Illus. Zeits. fur Ent., iii., p. 137). 



X". Halved. Left side c? , right ? . Antennae in exact accordance with the 

 two sexes. Body with 3 anal tuft on the left side, on the right side materially 

 stronger and fuller, running to a point at the anus (as in the 2 )• The left s 

 forewing, measured from the base to the apex, 33mm. long, the right 2 wing 

 36mm. The hindwings, in agreement with these dimensions, likewise of unequal 

 length, that is to say, in exact proportion to the length of the corresponding 

 forewing. The ground-colour of the left c? wings whitish-grey ; the transverse 

 bands, especially the central fascia, sharply laid on with brown, the latter with 

 distinct whitish median spot. The ground-colour of the right 2 wings more reddish- 

 grey, the transverse band more washed out, and the median spot indistinct. On the 

 underside of the left c? pair of wings the transverse bands distinctly visible, while on 

 the right 2 side they are scarcely to be recognised. This gynandromorph emerged 

 from the pupa on August 27th, while all the remaining examples of this brood came 

 out between May 10th and June 21st. A. Hoffmann coll. Cologne (in litt.) {loc. cit.). 



fi" — v" . Two further examples were bred in 1897. Descriptions of these 

 are wanting (cfr. E?itom. Jahrbuch, 1898, Report of the "Orion," p. 241J. 



£". Right side $ , left side 2 • Emerged from pupa in 1844 (Eyndhoven, 

 Alg. Konst en Letterbode, 1847, pt. ii., p. 149). 



0". Right side s , left side 2 • This example is smaller than the succeeding 

 'one, its abdomen is that of a 2 , the right <? antenna is thickened and characteristic, 

 the left 2 antenna fine. From Osnabriick. Oberthiir coll. (Oberthiir, in litt.). 



tt". Right side 3 , left side 2 • The example has the abdomen placed 

 slightly crosswise, is slightly deformed, on the right, enlarged and flattened. The 

 four wings are similar ; the insect is very large, well-developed as to its wiugs, 

 with all the markings clearly shown. From Clullons-sur-Saone. In Boisduval 

 coll. This is the specimen noticed by Boisduval [Species Gen., i., p. 24) as 

 being a magnificent gynandromorphous specimen which was given to him by 

 M. Martin, of Chalons-sur-Saone (Oberthiir, in litt.). 



p". A specimen bred from a Brighton larva, which has the left antenna 3 , 

 the right 2 ; the wings are hopelessly crippled; the body is 2 and full of eggs 

 (Fletcher, in litt.). 



a". Right side, wings small, <? , greenish-grey in colour ; left side, wings 

 considerably larger, 2 , reddish-grey in colour. Right antenna J 1 , left 2 . Bred by 

 Dahlstrom in Epiries from a dug pupa (Bartcl, Palaeark. Gross -Schmett., ii., p. 191). 



t" . Halved. Right side <f , left side 2 • Wings on the right side smaller 

 than on the left, paler coloured and weaker marked. The abdomen distinctly 

 divided medially by a longitudinal ridge, with longer hairs on right side.
