EREBIA EPIPHRON, ENOCH: ITS SYNONYMY AND 



FOKMS. 



By H. Rowland-Brown, M.A., F.E.S. 



(Continued from p. 152.) 



Meanwhile, an event of importance in the history of our 

 Erehia had taken place in Britain. In the original volume of 

 the ' Transactions of the Entomological Society of London ' (1812, 

 vi, p. 332) occurs the Urst description of the butterfly known to 

 succeeding generations as Erehia e-pivhron, var. cassiope. The 

 President, who is the industrious and reliable Adrian Hardy 

 Haworth, communicates " A Brief Account of some Rare Insects 

 announced at various times to the Society as New to Britain." 

 The date of publication is June 2nd, 1812, and No. 3 in the 

 list is : 



" Mnemon. Papilio (the Small Ringlet) alis supra nigro-fuscis, 

 fascia postica communi annulari, annulis coccineis. 



" Habitat in Scotia.''' 



" Obs. Statura et magnitude Pap. Pamphili. Alee anticce supra 

 annulis quatuor, horum tertius dimidiatus et aliquantillum exterior.

 cavum alarum. Subtus al£e cupreofusege, anticce puntis subtribus

'• In musaeo Dom. Francillon, a captore Dom. Stoddart. 



" Obs. I have not found any account of this species in the works 

 of Fabricius, Huebner, Herbst, or any other author in my possession." 



Haworth's find, indeed, was a variant form of Epiphron 

 apparently undistinguished at that time by the writers quoted, 

 and it remains var. Mnemon to this day. In a later part of this 

 paper I propose to trace the history of Epiphron and Cassiope in 

 the United Kingdom. At present, therefore, I content myself 

 with noting the discovery and original publication of the species 

 in Britain. As stated, its bibliography so far on the Continent, 

 with one doubtful exception, is all with the Germans ; and it is 

 well to note that none of them, de Villers included, hint at the 

 existence of the type form away from the scene of Enoch's 



* We now know that the original published locality of Mnemon was incorrect. 

 Stothard's examples, from which Haworth made his description, were derived from 

 English sources (cp. Dale's 'British Butterflies,' 1890).
