LÉPIDOPTÉROLOGIE COMPARÉE 89 



With this may be compared Fabricius's description of his 

 C. davHS from Hamburg {G en. Insect., p. 259) which is no doubt 

 I think, the same species and the same fomi thereof, especially in 

 view of the propensity of this butterfly to vary locally. 



" A Butterfly of moderate size. Fore wings above rounded, 

 fulvous (tawny), with two black blind eyes, and a third very 

 small one which is rather indistinct; beneath with a white stripe, 

 and with two eyes pupilled with white. Hind wings above darker, 

 with five or six blind eyes; beneath grey, with an interrupted white 

 stripe, and six black eyes with white pupils, the last double... 



The date of von Rottemburg's Natiirforscher is i77S-'^777\ 

 that of Fabricius's Gênera Inseclorum 1777, and it is very soon 

 after this time that we first hear of tiphon having been observed 

 in England. In 1795 {Les Insectes de la Grande-Bretagne, p. 51, 

 a bi-lingual treatise in French and English) Lewin figures and 

 describes it under the name of the " Argus de Manchester ", which 

 he wrongly identifies with the Hero of Linneus. 



" Il y a peu de temps, on connoissait à peine cette espèce de 

 papillons en Angleterre; ils sont plus connus maintenant, depuis 

 qu'un amateur en a découvert plusieurs dans un lieu marécageux 

 près de Manchester; et comme ils paroissent singulièrement atta- 

 chés au lieu de leur naissance, tous les ans, au mois de Juillet, il 

 en prend quelques-uns. Je l'ai figuré (la mouche) d'après un 

 papillon que j'ai trouvé dans la superbe collection d'insectes, soit 

 Anglois, soit étrangers, que possède M. Francillon. Le dessus est 

 représenté fig. 5, et le dessous fig. 6 " (Plate 23). 



The figures in question depict the same form — fhïloxeniis — 

 as we are accustomed to take in Lancashire now more than a 

 century after the publication of Lewin's book, but it was some 

 years before our British collectors realised that the species was 

 more widely spread. The butterflies which Donovan (Natural 

 History of British Insects, London, 1792- 18 16) figures on 

 Plate CLXXXVI under the title Papilio Hero, Scarce Meadow- 

 Brown Butterfly (we call Efinefhele jurtina the Meadow-Brown in
