butterflies of the French Pyrenees. 391 



head of the valley of St. Vincent it was so 

 numerous that I caught twenty in an hour or so, 

 and, when disturbed, it usually returns to the 

 same perch. 



25. T. rubi. E. — I did not observe this myself, but 



procured specimens from Michel Nou, taken at 

 Vernet. De Graslin says it is very common at 

 Collioure, and the specimens I have from there 

 have a median line of white spots on hind wings 

 below, which is more marked than in those from 

 any other locality. 

 ? T. quercus. E. — Noted by Struve at Vernet, but 

 never seen by Oberthur, who has collected several 

 years there. 



26. Polyommatus virgaureae. E. C. 3 — 6000 ft. June, 



July. — The var. Meigii, which differs from the 

 type in having more or less of the black spots of 

 the lower surface showing through the copper of 

 the wing above, occurs in the Pyrenees, but only, 

 I think, as an aberration, and, though it seems 

 more abundant and well-marked in Central Spain, 

 it can hardly be looked on even there as a constant 

 variety. 



27. P. hippothoe. E. C. 3—6000 ft. July.— Not un- 



common in moist pastures. 



28. P. alciphron, var. gordius. E. C. 2—3000 ft. 



June, July. — Common at Vernet ; also found at 

 Cauterets. 



29. P. dorilis. E. C. Var. subalpina. E. To 6000 ft. 



June, July. — Not common. Those which I took, 

 as also noted by Oberthur, are like the common 

 form ; but Struve notes also the var. subalpina as 

 occurring at Vernet. I do not think this variety 

 can be separated in the Pyrenees. 



30. P. phlceas. E. C. To 5000 ft. 



81. Ly ccena bcetica. E. C. To 8000 ft. May— July.— 

 Not noted by De Graslin, but taken by Struve 

 and myself at Vernet, and by me at Gavarnie and 

 on the Pic du Midi at 8000 ft. This latter speci- 

 men had one fore wing so much crippled that it 

 seemed hardly capable of having flown up so 

 high from below ; and, as the species occurs at 

 considerable elevations on the Himalaya, it may 

 be an inhabitant of the higher Pyrenees.
