328 BRITISH BUTTERFLIES. 



On the underside the $ is of a distinctly paler ground colour than the 

 2 . The hair-scales are numerous in the $ of this species. Pierce notes 

 the scales of this species as follows : — Male: (1) The androconia are 

 oval in outline, OOOlin. long, 0-0005in. wide ; there are eight rows of 

 twelve spots more or less coalesced into a line, crossing each scale. 

 At the base of the wing the androconia are much larger, sometimes 

 twice, when the measurements would be 0*002in. ( = 0-05mm.) and 

 O'OOlin. ( = 0'025mm.). [This latter is practically the measurement 

 given by Aurivillius (Bih. Svensk. Vet. Akad. HandL, v., p. 24), viz., 

 0-054 mm. long without the stem, O06mm. with it, and 0-025mm.- 

 0*027mm. wide.] (2) The transparent scales are rounded at the apex, 

 0*003in. xO0015in., deep bronze-yellow in colour, deepest at the apex, 

 and beautifully shaded to the base. (3) Dark scales similar, but with 

 four lobes. (4) The covering scales 0'018in. x -002in., with seven 

 very fine striae. (5) The underside scales are of many varieties, but 

 are generally three-pointed, and of various lengths. Female: (1) With 

 the same bronzy-yellow, shaded scales, but generally with two or three 

 lobes. (2) The darker scales more acutely pointed than in $ . (3) 

 Underside scales with two and three points, similar to those of $ . 



Gynandromorphs. — Several gynandromorphs of this species have 

 been recorded. The following are those of which we have notes : — 



a. — Of ordinary size. Left side <5 , right side ? ; on the body a tolerably 

 distinct division, the right side ventrally scaled with brown, the left with white ; 

 the left side dorsally with blue, the right with scarcely a blue hair visible. The 

 antenna on the right side shorter than on the left. The ? wings, on the right side, 

 brown, with reddish-yellow marginal spots, the forewing with a dark central spot ; 

 the 3 wings, on the left side, beautifully blue, with a narrow black border. The 

 fringes of all the wings similar. The right ( 2 ) forewing seven lines long, the left 

 ( <? ) forewing seven-and-half lines long. The underside of the wings differs little 

 on the two sides. In the Berlin Mus. (Klug, Jahrbucher, 1834, p. 256). 



(3.- — Regularly halved. Left side S , right side ? . Upperside and underside 

 typical in colour and markings. Found at Interlaken, Switzerland. Coll. Wiskott 

 (Wiskott, Lep. Zwitter, p. 13, pi. iii., no. 17). 



y. — Right side <? , left side ? . Taken at Ventnor in August, 1893 (Shipp, Ent. 

 Record, v., p. 98). 



8. — Right wings c? , left wings ? . Captured June 9th, 1900, near Reigate 

 (Goss, EnLMo. Mag., xxxvi., p. 208 ; Ent. Fee, xiii., p. 218). 



e. — Right side 3 , left side ? . Captured June 30th, 1889, by K. Jambary near 

 Budapest (Aigner-Abafi, Illus. Zeits. fiir Ent., v., p. 331). 



£. — Imperfect gynandromorph. In shape and colour $ , on all the wings 

 glittering blue J streaks and spots irregularly placed. Found near Amasia. Coll. 

 Wiskott (Wiskott, Lep. Zwitter, p. 13). 



7]. — Imperfect gynandromorph. In shape and colour ? . On the two right 

 wings shining blue d stripes. Captured near Amasia. Coll. Wiskott (Wiskott, 

 Lep. Zivitter, p. 13). 



6. — A so-called mixed gynandromorph, mainly ? . On the upperside all the 

 wings asymmetrically streaked with blue to the outer margin, and irregularly 

 covered with scattered blue scales.* The underside typical $. Abdomen 5. 

 Eggs apparently partly deposited. Regensburg (Schultz, Ent. Zeita. Guben, xx., 

 pp. 156-157). 



t. — Leftside $ (of the ab. eeronus), right side forewing that of a perfectly- 

 formed <? , nevertheless an equally (well-formed) ? hindwing, but with strong blue 

 scaling. Oberweiden, Lower Austria, June 4th, 1899 (Ilabich, Verli. Gesell. Wien, 

 lii., p. 142). 



k. — A ? in general characters, the wings on the left side, especially the hind- 

 wings, splashed and streaked with d" coloration. From South Devon, 1908 (Gibbs, 

 Proc. Ent. Soc. Lond., 1908, p. Ixii). 



X. — A partial gynandromorph, chiefly ? , but two-thirds of the hind wings of 

 typical <f coloration and markings (Hodgson, Proc. Ent. Soc. Lond., 1908, 

 p. lxxviii).
