butterflies of the French Pyrenees. 399 



94. E. Euryale. E. C. 5— GOOO ft. July.— I did not 

 find it common, and Oberthur says it is variable, 

 as it is elsewhere. 

 It will be seen from the above remarks that there 

 is still something to be done before the twelve 

 species of Erebia found in the Pyrenees are 

 thoroughly understood. Unfortunately there are 

 no resident collectors who can accumulate long 

 series, and see whether the supposed variations 

 are constant; but MM. Oberthur have done 

 much to clear up their obscurity, and we may 

 hope for another part of the ' Etudes Entomo- 

 logiques ' to be devoted before long to the Pyre- 



11GGS. 



95. Satyrus alcyone. E.G. To 5000 ft. July— The 



commonest of the genus at Vernet ; rarer in the 

 Hautes Pyrenees, where I found it as high as 

 5000 ft. at Gavarnie. 



96. S. circe. E. 2000 ft. July. — Not common at 



Vernet, where it settles on tree-trunks and not 

 on the ground, as most of the European Satyrus 

 which I have seen habitually do. This species 

 belongs to the group which is so well represented 

 in the Himalaya, and which has been separated 

 by Butler as Aulocera, though I do not a,s yet 

 know whether there is any good generic dis- 

 tinction. 



97. S. Briseis. E. To 4000 ft. {fide Struve).— I did 



not take this myself, but procured it at Vernet, 

 and Struve notes it as found at Mont Louis. 



98. S. semele. E. C. ? To 3000 ft. July.— I did not 



take this except near Vernet, but it doubtless 

 occurs to the westward. 



99. S. arethusa, var. erythia, and transitus ad Boabdil. 



E. — I insert this on the authority of M. Charles 

 Oberthur. I doubt whether the forms distin- 

 guished as erythia, Hub., dentata, Stgr., and 

 Boabdil, Ptamb., are constantly distinguishable. 



100. S. statilinus. E. July.— Not taken by myself, but 



occurs not uncommonly below Vernet. 



101. S.fidia. E. July.— On the dry hot hills between 



Vernet and Prades. 



102. S. acUea. E. — Taken by M. Oberthur near Vernet. 



103. Parage mcera. E. C. Up to GOOO or 7000 ft.
