butterfly, long ago wol! figured by Lewin (" Tlie Tnsncts of Great Britain . . . ," 

 tab. 37, fig. 5, 6; 4to ; 1705), and noted by him as taken on a chalk hill at Dart- 

 ford, Kent, is in my opinion certainly L. hylas, and not, as it has sometimes been 

 considered, an aberration of L. bellarijus {cf. also II. Donbleday, Zoologist, p. 8167). 

 It is just possible that, as in the ease of Lampides bxtica, stray examples of L. hylas 

 sometimes find their way to this country. 



Folyommalus cori/don, L. — The exceedingly fine series of 88 specimens of this 

 species includes 2 (? ^ of a liglit leaden-grey tint above, with hardly a trace of 

 blue ; one $ with entirely light hind-margins (var. fotohri, South, Entom., xxxiii, 

 p. lOf., plate III, fig. 4, 5), and another of the same sex, suffused above with black 

 almost to the end of the cell. Two fine specimens of the ? ab. ai/riqrapha, Bdv., 

 one " from Meek, 1887 " (C. W. D.), and the other " Newmarket." Several streaked 

 under-sides of both sexes, and others with the ocelli on hind-wings more or less 

 obsolete ; but the finest is a $ , normal above, but beneath of a pale and very 

 peculiar clear greenish-white tint, slightly rayed along the nervures of the hind- 

 wing with brown. All the usual ocelli are absent, except the discoidal lunule and 

 the submarginal row of the fore-wings, and two costal spots near base of hind- 

 wings ; the marginal orange lunules are well marked on the hind-wings, are well 

 marked and surmounted by faint black crescents, and the hind-margins of all the 

 wings are brown, regularly interrupted by white spots between the nervures. This 

 magnificent aberration is labelled " From J. G-. Ross, 1880 " (C. W. D.). 



Poli/ommatus adonis, F.— Several examples with the ocelli of hind-wings 

 beneath, except the discoidal lunule, obsolete or nearly so ; and seven more or less 

 blue ? 's labelled at side " ceronus, Esp.," one very striking, but somewhat crippled. 

 Poli/ommatns icarux, Rott.— This species is represented by no fewer than 107 

 specimens from numerous localities, those from Sligo, Orkney, and Armagh being 

 very fine and brilliant. Of aberrations, the most striking is a ? , quite ordinary on 

 the upper-side, but beneath modified much in the sanui manner as the remarkable 

 P. corydon above described ; the ground colour being clear whitish slightly rayed 

 with brown on the hind-wings, the discoidal lunules of the fore-wings, and the 

 submarginal series of orange spots with their surmounting black lunules very 

 clearly and distinctly marked, but otherwise almost immaculate. This fine form 

 was taken by J. C. Dale in Dorsetshire, on August 5th, 1826, and is labelled at side 

 " Aug., 1826, Buckland." Another ? , in which the outer row of ocelli on the fore- 

 wings is elongated into strong black streaks, is labelled " Ilarwood, Colchester, 

 1899" (C. AV. D.). There is a fine <? of a beautiful pale lavender-purple tint 

 above, labelled " G-. King, 1859 " (J. C. D.), and at side " Labienits, Jerrayn " ; and 

 a very handsome ?, " Glanvilles Wootton, June, 188S " (C. W. D.), is very dark 

 above, the outer third of the hind-wings light lavender-blue with submarginal black 

 spots, the apex of the fore-wings also broadly blue. 



Polyommatus astrarche, Bergstr. — Two of var. alloils, Hiibn. (one from Castle 

 Eden Dene), quite immaculate above ; a ? from Langport, Somerset, with clear 

 white black-centred spot in cell above, "taken by Edward Paul, Esq.," is recorded 

 by J. C. Dale in the "Naturalist," vol. i, p. 16. There are 21 examples of the var. 

 salmacis, Steph., and 23 of var. artaxerxes, Fab. 



Polyommatus s-gon, Bork,— A very fine gynandromorphous example, the right
