BRITISH BUTTERFLIES. 



the darker scales are similar in size and shape, but are four-lobed. 

 The underside scales are three-pointed. Aurivillius writes of the 3 

 scaling of this species (Bih. Svensk. Ak. Handl., v. p. 25): The andro- 

 coniahave 5-6 rows of dots running down them (see figs. 16-17); length 

 with stem O06mm., without stem 0O54mm., width 0026mm. ; the 

 hair-scales (fig. 18), which must not be confounded with the real hairs 

 which thickly cover the base of the wing, are, as in the former species 

 (thetis, Bott.), flattened, narrow, of even width, with broad base which 

 does not end in a stem, but enters in the socket with its entire width ; 

 the length of these 0-24mm.-0*28mm., the greatest width 0'008mm. 

 The hair-scales are found in the same rows as the androconia, but are 

 larger and wider than they. 



Gynandromorphism. — There are many gynandromorphs of this 

 species recorded in various magazines, etc., the specimens themselves 

 being mostly in well-known collections. It is difficult, however, to 

 trace the older examples, and possibly others exist that have never 

 been recorded. We have, however, Unearthed enough to give some 

 very interesting results, and have arranged them roughly so that 

 somewhat similar forms follow each other : — 



Halved — Forewings $ , Hindwings $ . 



a. — Forewings s , hindwings ? . C. S. Gregson coll. (Mosley, Illus. Vars* 

 Br. Lep., pt. 7, pi. iii., fig. 3). Now in the Webb coll. 



Halved — Left side $ , Right side $ . 



a. — Left side $ , right side ? . The antennae similar. The right side ? with 

 weak blue scaling on the inner margin of the hindwings ; the left side s . The 

 underside as in the corresponding sexes. The abdomen ? , but scaled with blue 

 above. In Mazzola's collection (Ochsenheimer, Die Schmett., iv., p. 187 ; 

 Rudolphi, Abhandl. der Ak. Wiss. Berl., 1828, p. 51; Burm., Handbch. der Ent., 

 i., p. 339; Lefebvre, Ann. Soc. Ent. Fr., 1835, p. 146). In the Vienna Museum 

 (Schultz, III. Woch. fiXr Ent., i., p. 322; Kiihl, Pal. Gross- Schmett., i., p. 268), 

 but Riihl erroneously says, " Eight side cf , left side ? ." 



j3. — Left side c? , right side ? . Captured near Coventry in June, 1833. 

 [Recorded with the remark that Capt. Browne, in his book of Butterflies, mentions 

 five or six similar ones.] (Clarke, Field Nat. Mag., L, p. 229 with fig. ; Schultz, 

 Illus. Woch. fur Ent., i., p. 322). 



y. — Left side cT , right side ? . Mr. Pugh exhibited at the meeting of the 

 Northern Entomological Society, on June 26th, 1858, a hermaphrodite P. alexis, 

 taken by himself on the coast, the s characters being shown on the left side of 

 the body ; the $ side remarkably well-developed, the red spots being very large 

 upon both fore- and hindwings (Zoologist, xvi., p. 6190). 



5— Left side <?•, right side ?; right hindwing torn. The underside also 

 showing sexual difference in coloration. Labelled in Zeller's handwriting " Icarus 

 hermaphroditus. Zebe, lit. xii., '49." British Museum coll. (at present placed 

 among the teratologicals) (Tutt). 



e. — Left side <? , right side ? , both wings and antennas ; on the left side the 

 thorax and abdomen are blue, on the right side brown. Captured June, 1875, at 

 Meulan, Seine-et-Oise, by Testelin. (Bellier, Aim. Soc. Ent. Fr.. 1875, p. xiv). 

 We possess a specimen from the Bellier coll., left side <f , right ? , taken at Meulan 

 (Oberthiir, Etudes, xx., p. 23). 



'<;. — Left side <? , right side ? . From the Boisduval coll. (Oberthiir, Ktudes r 

 xx., p. 23). 



t). — Leftside & , right side ? (Heyne teste Schultz, III. Woch. fur Ent., iii., 

 p. 103). Taken at Autun. Constant coll. (Oberthiir, Etudes, xx., p. 23). 



6. — Left side S , right side ? . Briggs' coll. Exhibited November 4th, 1875 r 

 by Mr. C. A. Briggs (Ent. Bio. Mag., xii., p. 166 ; Ent., xi., p. 101 ; Schultz, III. 

 Zeits. fur Ent., iii., p. 103). Captured on the downs at Folkestone by T. William- 

 son, and given by him to C. A. Briggs. Sold at Stevens', October 22nd, 1896, for 

 £3 5s., to Doncaster (Briggs, in litt.; Ent. lice, viii., p. 272).
