LEPIDOPTEROLOGIE COMPAREE Ql 



Soon after, James Duncan of Edinburgh (A 'Natural Hïstory 

 of British Butterflies) not only repeats the English localities of 

 the species, but is able to inform us of its abundance " last summer 

 (1832) in Sutherlandshire, as well as in others of the more northern 

 counties of Scotland; and we hâve received it from Argyll and 

 Perthshires "; and Mr. Wailes is taking it frequently near 

 Newcastle. 



By this time, also, the nomenclature of the species has become 

 a hopeless tangle, from which, perhaps, it is hardly safe to say it 

 has been satisfactorily rescued in the twentieth century. Yet, the 

 plates of Lewin's and Donovan's works give us a fair indication 

 of the butterflies described though the same cannot be said for 

 the crude productions of the " Naturalists Library " which, pre- 

 tending to figure the Scotch forms are in every way inferior to 

 Borkhausen's original présentation of the northern form of fifty 

 years earlier. The two figures on the frontispiece of his (Natîir- 

 geschicte der Europaischen Schmetterlinge, Part I, Frankfurt, 

 1788) are of an unocellated ochre yellow Q (?) and an under- 

 side Cf (?) in which the basai and médian area of the fore wings 

 is rather dark brown; the hind wings showing traces of transverse 

 markings from the costal margin, with a single small ante- 

 marginal spot. 



His description (pp. 91-92, loc. cit.) may be translated as 

 follows : — 



" At présent I consider this butterfly also as a distinct species 

 rather than a variety. It is as large as arcania. The ground 

 colour of the four wings is ochre yellow which gets stronger 

 towards the border, without spots and markings. The fore wings 

 underneath hâve grey tips with a single eye. The hind wings are 

 grey underneath and hâve at the border two small pallid eyes of 

 différent sizes, the smaller of which is blind. The white band 

 which in others traverses the middle of the wing is hère wanting, 

 and instead of it one sees on every spécimen only two unequal pale 

 white hal.f-moon-shai3ed spots (Cp. the accompanying plate) ".
