EREBIA GAVARNIENSIS, WARREN. 47 



leporina, Coenobia rufa and Hi/penodes costaefitrifialis, the la^t species at 

 sugar. A tdp to Box Hill on July 13th, 1911, was most successful, 

 resulting in four IJt/uisia dcplana (helrenla), Boannia ahictaria, 

 Melanthia procellata, Geoinctva vernaria, Phihalaiitevyx termta, P. 

 ritalbata, and one Aventia flexula. I also took H. taenialis at sugar in 

 Ifield Woods in some numbers. 



In August I found lAthma cowplana (common, but local), one 

 Charaeas (jrawinis, Noctua mithrom, Triphacna janthina, and pupte of 

 Nonafjria arundinU {typhae) in old bullrush stems. In Worth Forest I 

 met with Lyi/ris testata, F^tipitliecia expallidata, Anarta luyrtilli and 

 Noctua dahlii. 



In September there occurred, at the gas lamps, OrthoUtha cervinata, 

 Coreinia ferriKjata, Ennovios fii.icantaria, Mesoleiica ocellata, Liortyna 

 oehracen {fiavayo), OmphaloaceUnlnnoRa, and Hydraecia micacca, and also 

 one ? Acidalia si(bsericeata, from which I obtained about a dozen ova, 

 the larvte from which are still (December) feeding. I also took one 

 Crorallis elinynaria, and, on the rushes, Tapinoxuda fidva. Towards the 

 end of October and November the lamps produced CheUnaUibia boreata, 

 C. brumata and Oporabia dilutata. A trip to Worth Forest in early 

 November produced, besides the last-named insects, Oporabiaantuuinaria, 

 Hybernia aurantiaria and H. defoliaria. Diloba caerideocfpliala, 

 Hiiiiera pennavia and Poecilocaiiipa popiili, were also visitors to the gas 

 lamps at Horley. At ivy, in the Box Hill district, I took Ochria aarayo, 

 AwatJies macilento, Miselia oxyacanthae, Cerasth vaccinii, C. fipodicea, 

 etc., and, over the juniper bushes, Thera juniperata. 



Erebia gavarniensis, Warren = Papilio petrosus, De Prunner. 



By H. ROWLAND-BROWN, M.A., F.E.S. 



At the risk of becoming tedious, I venture to supplement my 

 previous note on Erebia yavarniensis, Warren {antea vol. xxv., p. 294), 

 with a few further remarks on the subject of the nomenclature of this 

 " all-black " butterfly. When writing in November I had not access 

 to the earlier authorities, though I seemed to remember that a " totiis 

 niyer," Erebiid, other than plitto, Esper, had received attention long 

 before Boisduval's Catalogue appeared, and even before inanto var. 

 caecilia had been figured by Hiibner. However, I think I am now in 

 a position to show that Erebia yavarniensis, Warren, is no other than 

 the Papilio petrosus of Leonardo de Prunner. 



In the " Supplementum Papilionum quos Comes Excoffier di Lizzolo 

 .... mihi obtulit," published with his Lepidoptera Pedemontana, at 

 Turin, in 1798, he describes (p. 71) this butterfly as " Alis integerrime 

 fusco-atris, ;tias et foemina aeyuales. Alpibus invenitur niensibus Mali 

 Jmiii frequens." That is all. Staudinger ignores petrosals altogether in 

 the various editions of the Cataloy ; but Kirby is more enterprising, 

 and we find, Synony^nic Cataloyue of Diurnal Lepidoptera, vol. i., 

 p. 62, under ?\y)iiphalidae (^Maniola) : — •
