butterflies of the French Pyrenees. 397 



87. E.Evias. E.G. 5— 7000 ft. Juno, July.— I found 



this only near Vernet at highish elevations, but 

 de Graslin says it occurs also low down, as it 

 does in the Valais, where I have taken it at 

 3000 ft. in May. My specimens are perhaps 

 smaller, but I do not think can be separated from 

 the Swiss Evias, though Staudinger, in his 

 collection, has separated a form as var. pyrenaica. 



88. E. melas forma pyrencea, Ob. E. 7 — 9000 ft. July. 



Cf. Oberthiir, Et. Ent., viii., pp. 20— 24.— E. 

 melas forma Lefebvrei, Boisd. C. 7 — 9000 ft. 

 July. — Oberthiir has written so much on the 

 varieties of this species that I need say no more, 

 but, if the true Lefebvrei of the Hautes Pyrenees 

 was not connected by intermediate forms with 

 that of Mt. Canigou, as Oberthiir states it is, it 

 would be better worthy of specific rank on account 

 of the differences in both sexes than many species 

 of Ercbia which are looked on as distinct. It is 

 curious that this species, which is found nowhere 

 in the Alps west of Carniola, should reappear in 

 great abundance in the Pyrenees, and that the 

 form of the Eastern Pyrenees, as well as that 

 found in the Picos d'Europa in Northern Spain, 

 should both be much nearer to that of South- 

 eastern Europe than the Central Pyrenean form. 

 I found it abundant in certain places where the 

 mountain slopes are covered with great stones and 

 boulders. It is difficult to catch, unless a grassy 

 spot can be found among or near these great 

 stone-heaps, where running is impossible ; but I 

 took thirty males and two females in about two 

 hours in one place above Vernet, and could have 

 caught nearly as many on the Pic du Midi, if I 

 had had time. 



89. E. lappona. E.G. 6— 9000 ft. July. — Common 



on the road to Pla Guilhelm, above Vernet, where 

 the specimens do not differ from those found in 

 the Alps ; but the form taken in the Hautes 

 Pyrenees, which has been named sthennyo by 

 de Graslin, differs in the absence of the brown 

 band on the fore wings, in which the black spots 

 are enclosed; and those which I took on the 

 Pic du Midi and near Gavarnie also differ in the
