170 BRITISH BUTTERFLIES. 



somewhat large swellings, fairly wide apart ; length (without the 

 stalk) 0054mm. (with it, O06mm.), width 0*023mm. The hair-scales 

 are wanting." 



Gynandromorphs. — There is, without doubt, a considerable number 

 of unrecorded gynandromorphs of this species in various collections, 

 and the following can only be looked upon as a small proportion of the 

 actually existent examples ; still, they are the only ones to which we 

 have references : 



a. Apparently a brown 9 , but showing on examination under the microscope, 

 a number of J androconia on the left side. There are very few transparent 

 scales, and the other scales are quite typical brown J and 9 scales ; the genitalia 

 are also of ordinary 9 form (F. N. Pierce, in lift.). 



/3. Eight side <? , left side ? . Obtained by purchase from Mr. Hodgkins 

 (Gregson, Ent., iii., p. 211). 



7. Right side <3 , left side 9 . Captured July, 1875, at Folkestone (Briggs, 

 Ent., xi., p. 101 ; Ent. Mo. Mag., xii., p. 166). 



5. Right side J , blue, left side 2 , brown ; captured in the New Forest in 

 1890, 2 side larger than $ (in litt., Miss H. Clark). Gynandroniorph exhibited at 

 meeting of City of London Ent. Society, April 27th, 1897 (Clark, Ent., xxx., p. 179). 



e. Halved. Left side <? , right side 2 . Taken in the summer of 1892, in the 

 neighbourhood of Stade (in litt., Eggers) (Schultz, Wpch.fur Ent., ii., p. 364). 



£. Halved. Left side ? , right side $ . The two halves in all respects 

 ■characteristic of the sexes, including the genital organs. The left wings larger 

 (12mm.) than the right (10mm.). Found on the Albula Pass. In " coil. Wiskott," 

 Breslau (Wiskott, Lep. Zioitt., p. 11). 



77. Halved. Left side <? , right side 2 , in colour and shape. Right wings 

 12mm., left 10mm. Found in Upper Bavaria. In "coll. Wiskott" (Wiskott. Lep. 

 Zwitt., p. 11, pi. iii., fig. 16). 



6. Left side <? , right side ? . Taken July 12th, 1904, near Canterbury 

 ^Small, Ent., xxxvii., p. 263). 



1. Right wings $ , left wings 9 . In the " Dale coll." (Dale, Hist . Brit. Butts., 

 p. 79). A very fine gynandromorphous example, the right side being J , and the 

 left side ? , the sexual differences being equally well-marked on the underside. 

 Labelled from "J. G.Ross' coll. (C.W.D.)." In the "Dale coll.," at Oxford (Walker, 

 Ent. Mo. Mag., xliii., p. 133). 



k. Left side d , right side ? . Not further described (Gillmer, Ent. Zeits. 

 Guben, xx., p. 140). 



X. Right side $ , blue with a broad black margin, the forewing from base to 

 apex 10mm. Left side 9 , unicolorous brown, the forewing from base to apex 

 13mm.* (Grund, Int. Ent. Zeits. Gub., ii., p. 71). 



fi-%. Three gynandromorphs in Staudinger's coll. (in litt.) (Schultz. Hint. 

 Zeits. fur Ent., iii., p. 364). Dadd (in litt.) reports on these as follows : 



p. Right side S , left side 9 . From Arolsen (teste Bang-Haas). 



v. Right side 9 , left side J . Locality unknown (teste Bang-Haas). 



ij. Right hindwing partially blue-scaled; left forewing partially blue-scaled. 

 From Vienna (teste Bang-Haas). [The genitalia of this example should be 

 ^examined carefully ; it may be only a blue-tinted 9 .] 



0. Left side cf , right side 2- The 2 half is larger (forewing 13mm.) and 

 entirely normal above. The specimen being somewhat worn, the markings of the 

 underside appear confusedly through. The d" half is smaller (forewing 10'5mm.), 

 blue, with the exception of the wide marginal border which, is black. Here also are 

 seen through the wing, but indistinctly, the markings of the underside, the hi 11c scales 

 being separated and mixed with many brown scales. This circumstance, with others, 

 leads meto assume that, in this example, the ? charactersdominate, e.g., on the outer 

 margin of the left hindwing (d side) between the margin and the blue portion, in 

 four cellules, are well-denned yellow-orange marks as in the ? , this feature being 

 well-marked on the right side. The fringes arc brownish on both sides, darker on 

 the right, especially above, and intermixed with white on the left side, but not of 

 so pure a white as in the typical 6 • The coloration and markings of the underside of 



* It will be observed in this specimen, and in those marked 8, f, 77, and 

 x, the 9 side 18 larger than the d , a very remarkable fact, as, in any given locality, 

 the <r b of this species are usually larger than the 9 s.
