liyj, THE ENTOMOLOGIST. 



and from the completeness of his observations we may be sure 

 that he had a first-hand knowledge of both Einjihron and Cassiope, 

 which, none the less, he continues to treat as distinct. Indeed, 

 Freidrich Treitschke, his collaborator, informs us that his 

 colleague had received examples of EpipJiron from Enoch 

 himself. In the diagnosis of the first-mentioned species (' Schmett. 

 V. Eur.,' Bd. i, Abtheil 1, p. 258, No. 41), the white-pupilled 

 ocellation of the female is recorded as a sexual character, and 

 as Dr. Buckell remarks (' Ent. Eecord,' vol. v, p. 162), we are 

 l^resented with three new characters : (1) "A greenish gloss on 

 the upper surface ; (2) a. projection from the centre of the hind 

 margin of the hind wings ; (3) the occurrence of a reddish 

 coloration over the disc of the fore wings on the under surface." 

 But Enoch's localities in the Harz are still, it seems, the only 

 known habitat of the species. 



Ochsenheimer's account of Cassiope is also excellent in detail ; 

 and we now hear of it for the first time as a Swiss species. " Alis 

 integris fuscis fascia rufa, punctis tribus nigris ; posticis supra 

 maculis rufis nigro-punctatis, subtus fteminse cinerascentibus, 

 punctis solis." Upon which follows an accurate description 

 of both sexes. 



Ochsenheimer's and Treitschke's publication covers a long 

 period of years from 1807 to 1835. In vol. x (1834) Treitschke 

 has come to the conclusion that EpipJiron and Cassiope are one 

 and the same species. Fr. Meissner, in the ' Naturwissenschaft- 

 licher Anzeiger der Allegemeiner Schweizerischen Gesel. fiir 

 Naturvissenschaften,' published at Bern in 1818 (Erster 

 Jahrgang, p. 71), deals with Cassiope from the high Alps only, 

 and distinguishes it from Melampus, though the remark, " die 

 Unterseite der Hinterflugel ist stets einfarbig braun, ohne alle 

 flecken," leaves us still in some doubt as to the form of the 

 butterfly under his observation.

SOME NOTES ON THE COLLECTION OF BKITISH 



MACRO-LEPIDOPTEEA IN THE HOPE DEPARTMENT 



OF THE OXFORD UNIVERSITY MUSEUM. 



By F. C. Woodforde, B.A., F.E.S. 



The original source of this collection was the presentation 

 to the Oxford University in 1849 by the Rev. F. W. Hope of all 

 his very extensive collections of books, prints and zoological 

 specimens, including that of the British Lepidoptera. This 

 latter he augmented in 1857 by the purchase of the private 

 entomological collection of Mr. J. 0. Westwood, and the two 

 were henceforward known as the " Hope-Westwood Collection."
