IPHICLIDES PODALIRIUS FEISTHAMELII, AND 

 MELANARGIA LACHESIS IN THE WESTERN, AND 

 EASTERN PYRENEES. 



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



My note on Iphiclides podalirius feisthamelii, Dap., in the 

 Pyrenees following Mr. McClymont's observations (antea, 

 pp. 91-92) was already in the press when I received from my 

 friend, M, P. Rondou, of Gedre, a copy of his 'Lepidopteres 

 nouveaux pour la Faune Pyreneene ' (Proces-Verbaux de la Soc. 

 Linn, de Bordeaux, 1906 and 1916). The later extract contains 

 an interesting note on the possible extension of feisthamelii in 

 the western Basses-Pyrenees, which calls for some comment. 

 As is well known, I believe, typical podalirius is not reported 

 from Spain. Seebold, in his ' Catalogue of Bilbao Lepidoptera,'* 

 reports that at Bilbao feisthamelii entirely supersedes the type. 

 Thus, M. Gelin, one of the joint authors of the * Catalogue des 

 Lepidopteres observes dans I'Ouest de France,' suggested some 

 years ago to M. Rondou that feisthamelii should reach north- 

 wards into France in the west, as in the east. " From the fact 

 that no one has reported it yet " (?. e. 1900), " it does not follow 

 that it does not occur there," he writes. But in their catalogue, 

 first published in the ' Memoires de la Soc. Hist, et Scient. des 

 Deux-Sevres.' Niort, 1912, MM. Gelin and Lucas make uo 

 mention of the occurrence of feisthamelii in the French Biscay 

 country, and having visited localities myself from Hendaye to 

 Bayonne in 1891, 1905, and 1911, I can testify that the type 

 asserts itself completely in this direction, and that, I think, is 

 also the experience of the several British collectors, including 

 Miss K. M. Hinchliff, Mr. H. J. Elwes, Mr. A. H. Jones, anct 

 Mr. W. G. Sheldon, among others who have explored the ;-ame 

 region. I should say, therefore, that feisthamelii does not cross 

 the Bidassoa ; it will be interesting, however, to determine if, on 

 the Spanish side between Bilbao and St. Sebastian, the type over- 

 laps the variety or subspecies. Seebold does not help us. Plis 

 catalogue is strictly confined to the environs of Bilbao, and there
