Swiss Diurnal Lejndoptera, 215 



guished [there seems to be an omission here] which 

 runs from the centre spot on the under side of the 

 hind wings, towards the edge. In the vicinity of 

 Meyringen, in Oberhasli ; in August, but not often. 



103. Eumedes Meisn. A hitherto undescribed species; not 

 rare about Berne in August; intermediate between the 

 two last, which are not found near Berne ; but distin- 

 guished by the darker blackish brown of the upper 

 side, and the chequered margin ; the under side comes 

 nearer to Agestis. (Ochsenheimer knows nothing about 

 it, as he says in three words, " mir ganz unbekannt." 

 Nor does Boisduval or Gbdart take any notice of it). 



104). Optilete. Higher Alps, as Grimsel, Scheideek, Wen- 

 gen ; rare. 



105. A'rgus. Very common, especially about Sierre in the 



Valais ; varies much, particularly the female, which is 

 either with or without the blue tinge. 



106. iE v gorc. Rather rare about Berne; but very abun- 



dant about Sierre in Valais, where the female varies 

 much. 



1 07. iEgidiow Meisn. In the higher Alpine valleys, as the 



Ursernthal (St. Gothard) ; and also on the Higher 

 Alps, as the south side of the Grimsel (very similar to 

 iETgoM ; but Meisner thinks it distinct. Ochsen- 

 heimer says it is the Philonomus of Borkhausen ; a 

 species not mentioned by Godart or Boisduval). 



108. Amyntas. In August, about Berne; not common. 



109. Polysperchorc. In spring; not common. {Boisduval 



makes it a variety of the last. ) 



110. Coretas SchifFermuller. Taken by Professor Studer in 



Lower Valais. 



111. Hylas. Rare about Berne, in May. It seems to be 



double-brooded; at least in the Valais, where it is 

 found in August. 



112. Battus. Irnisserstalden, above Giornico, and thence to 



Dazio (Tessin). Not rare in August. 



113. Hell*?. This species, which is found, in May and Aug., 



in the wet marshy meadows about Leipzig ana], other 

 parts of Germany, is, with us, truly Alpine,, and 

 appears in June and July. I first found it, in 1808, 

 on the Molesson (near Freiburg) ; and, since, on the 

 Upper Gurnigel. It is, probably, on all the mountain 

 chains. 



114. Circe. Everywhere, in May, August, and September; 



the female varies much in size, as well as in the lighter 

 or darker colour of the upper side,
