A BUTTERFLY HUNT IN SOME PARTS OF 

 UNEXPLORED FRANCE. 



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



(Continued from p. 308.) 



(ii) The Basses-Pyrenees. Eaiix-Bonnes. 



I CAN hardly claim any particular originality in the choice 

 of the hunting-grounds described in the first part of this paper. 

 The coast from Biarritz to St. Jean de Luz is by no means 

 " unexplored." On the contrary, many British collectors on 

 the way to Spain, or returning from the Central Pyrenees, have 

 visited this region, and given us the benefit of their experiences. 

 The reason I selected Guethary was the reputed abundance of 

 Coenonympha oedipus in that locality, and if Gu6thary failed us, 

 then there was Biarritz only a little way off, where I had over- 

 taken the rear-guard of the species in August, 1905 (Entom. 

 vol. xxxviii. p. 273), and three weeks earlier in the field might 

 ensure a bag of this interesting butterfly in good condition. 



Our opening day, July 2nd, was not auspicious — hazy, with 

 mist blowing in from the sea, and the not-very-distant Pyrenees 

 cloaked with heavy cloud. There were, however, gleams of sun- 

 shine at intervals, but neither then, nor at any time, were 

 butterflies on the wing. I attributed their absence,, of course, 

 to the weather ; but in the event the only conclusion possible 

 was that Guethary as a hunting-ground was a failure. Both 

 on this day and the 4th, when the sun shone brilliantly, we 

 quartered the country inland for miles over what suggested an 

 ideal ground for our purpose — marshy heath and rough pasture, 

 with occasional scrubby oak-woods. But C. oedipus wa,8 nowhere 

 to be found, only the commonest species ; my own captures 

 being limited on these two occasions to two very fine Lampides 

 hoeticus (females), the largest I ever saw, a few fresh Brenthis dia, 

 and one fine Colias edvsa ab. pallida ; though Mr. Warren took 

 several more of the latter in the rough fields near the clifis. 

 The only really plentiful butterfly in evidence on the heaths was 

 liusiicus argus, L. {(egon) — all males ; while a battered female
