dull copper, wliitish towards the anal angle of fore-wings, and another of the same 

 sex is light dull brown with hardly any metallic tinge, but the black spots large and 

 clear. Two specimens have the submarginal copper band of hind-wings reduced to 

 one or two elongate dashes, and a curious-looking ^J lacks the submarginal black 

 spots on fore-wings. Several approach the dark ab. deu^, F., and one is a very 

 well marked example of that form. 



Polyommalus alsus, L. — One or two from Dover, almost immaculate beneath. 



Li/ca-na bxflca, L. — Two examples ; a J in fair condition, but badly set, 

 "From J. G. Ross, 1882, who had it from boy who took it in Devonshire" 

 (C. W. D.), " Dartmouth " at side. Another <J , under-side, in fair condition, on 

 a large common pin, " Elton, Trin. Coll., Camb." ; " Andover" at side. 



roli/ommatus ach, W. V. — A very fine series of 19 sjiecimens, including several 

 from Glanvillcs Wootton. One S " Fi'om J. G. Rojs, 1878 " (C. W. D.), is labelled 

 at side " Cardiff." A fine c? has the ocelli on under-side very conspicuous, enlarged 

 and somewhat elongated, and in another J they are almost absent. 



Polyommatus avion, L. — Fifteen specimens, chiefly from Barnwell Wold and 

 Langport, Somerset. Two have the black spots on upper-side nearly obsolete, and 

 in another way they are mueh enlarged and elongated. 



" Polt/omniatiis alcon, Steph., var." — Under this name is a s|)ecimen set to 

 show the under-side, very old, but quite good, except that the abdomen is missing. 

 On a triangular label is " Alcon, Hub., 203, W. J.," and at side " n. Bedford." 

 The reference in C. W. Dale's " Register " is " var. alcon, Steph , from Mr. Ifaworth, 

 H. Jones, Cliefden, Bucks." Whatever the origin of the specimen, it is almost 

 certainly not a variety of arlon, but agrees in every particular with specimens of 

 Lycsena alcon, F., in the Oxford Museum and in my own collection. Cf. Stephens, 

 111. Haust. I, p. OS. 



Lycwna arglades,'Pi\\\. — A jiair in good order; the J has a circular ticket, 

 " Dr. Marsh, 1S74, Whatley " ; the $ , " Whalley, Somerset," at side. These would 

 appear to be the specimens recorded by the Rev. J. Seymour St. Jolm, in " Entomo- 

 logist," vol. xviii, p. 292 (1885). 



Polyommatiix dorylait, Iliibn.- One $ , set to show the under-side, in fine con- 

 dition, on a modern English pin leaning very much forward as is the practice with 

 many English Lepidopterists. The label is very illegible, but appears (o read 

 "Eurney's Sale, 1893, from Cooke, Zoologist, 8402 " (C. W. D.). At p. 8402 of 

 the " Zoologist " is a note from Henry Doublcday, dated Jaiuiary 12th, 1803, as 

 follows: — " Mr. Cooke, of Oxford Street, recently detected two specimens of (his 

 species among a number of Adonis taken in England which he had purchased. 

 One of these I have seen and it is certainly L. don/fax, and now that attention lias 

 been called to it, the insect will probably be met with in the coming summer." 

 Mr. Dale's specimen is in all respects identical with Lycnuia hylas, Esp. (— - dori/lns, 

 Hiibn.), of which species a s])ecinien, "caught at Dover on 7fh Se])tember, 1002," 

 was exhibited b^' Mr. Sloper at the meeting of the Entomological Society of 

 London on October 15th of the same year (Proc. Ent. Soc, 1902, p. xxxii). The 

 butterfly, long ago well figured by Lewin (" The Insr^cts of Great Rritain . . . ," 

 tab. 37, fig. 5, 6; 4to ; 1795), and noted by him as taken on a chalk hill at Dart-
