390 Mr. H. J. Elwes on the 



13. A. car diamines. C. To 5000 ft. July. — Not observed 



in the Eastern Pyrenees, but found at Luchon 

 and Cauterets. 



14. Leucophasia sinapis, and var. diniensis. E. C. To 



6000 ft. May— July. 



15. Colias edusa. E. C. To 5000 ft. June, July. 



16. C. phicomone. E. C. 6—8000 ft. July.— Very 



abundant above Vernet. 



17. C.hyale. E. C. July — August. — I did not observe 



this, but M. Oberthiir says it is common at Vernet 

 in August. 

 C. chrysotheme is noted by Struve as occurring at 

 Vernet, but I think he must mean what I took, 

 and De Graslin notes as " C. edusa variety ap- 

 proaching chrysotheme." These were small pale 

 forms of edusa, which occurred at the same time 

 and place as the large brilliant ones which are 

 typical of hot sunny climates. I am not aware that 

 C. chrysotheme occurs anywhere west of the Tyrol, 

 where, I think, it was once reported by G. Mann. 



18. Rhodocera rhamni. E. C. 2—8000 ft. March- 



June, ^rfe de Graslin; July, Elwes. 



19. R. Cleopatra. E. 1—2000 ft. June, July.— Com- 



mon at Vernet. 



20. Thecla betulee. E. — I procured a specimen of this 



taken at Vernet by Michel Nou. Neither de Gras- 

 lin or Struve note it. 



21. T. spini. E. — Noted by de Graslin at Villefranche, 



just below Vernet. I took a female of the form 

 Lynceus at Vernet. 



22. T. ilicis, and vars. cesculi and cerri. E. C. 1 — 3000ft. 



June, July. — Common at Vernet. Neither the 

 var. cerri, which, according to Oberthiir, exists in 

 both sexes in France, or the var. cescidi, which, 

 according to Staudinger, is a southern variety, 

 seem to me quite worthy of separation. 



23. T. acacia. E. To 3000 ft. June, July.— Not so 



common as the last, but occurs early in July at 

 Vernet. 



24. T. roboris. E. 1—3000 ft. June, July. — This 



fine species is common at Vernet in several places; 

 it settles on ash and chestnut trees, and is not 

 difficult to catch in good condition at the begin- 

 ning of July. On some of the low trees at the
