Many of these are high northern and alpine species, 

 or frequenters of peat-hogs, which are rare in the 

 Pyrenees. 



Of the species found in the Pyrenees, hut not in the 

 Alps, some are inhabitants of the more arid region of 

 Southern France, such as Melanargia lachesis, Erebia 

 neoridas, Cosnonympha dorus, Satyrus fidia, and only 

 found in the drier parts of the Eastern Pyrenees; whilst 

 others, such as Thecla roboris, MeUtcea dejone, are rather 

 Spanish than French species. Lyccena pyrenaica, if 

 really distinct from orbitulus, is the only one absolutely 

 peculiar to the range, and Erebia melas is an inhabitant 

 of South-eastern Europe ; its variety Lefebvrei, however, 

 seems to me to have quite as good a claim to be con- 

 sidered distinct as L. pyrenaica, and, were it not for the 

 great variation which is found in the forms of melas, I 

 should say that it was so. 



In going through Staudinger's Catalogue, I find, 

 among the Dombyces, the following species, which are 

 supposed to be confined to the Pyrenees : — 



Zygcena anthyllidis. 



Emydia cribrum, var. Rippertii, which Struve thinks 

 is a distinct species. 



Hepialus pyrenaicus and //. alUcola. 



Psyche Leschenaultii. 



Orygia aurolimbata, of which, however, a, variety 

 occurs in Spain. 



Among the Noctuce I do not find a single species 

 recorded. Among the Geometrce, the following : ( 'leogene 

 peletieraria, which differs only in the male sex from 

 ('. niveata of the Alps; Ortholitha calinaria. Eupithecia 

 cyneusata, of which a single female only has been taken.
