Swiss Diurnal Lepidoptera. 207 



6. Phce'be. Common in the Valais ; July and August. Was 



once taken at Wohlen, two leagues from Berne. 



7. Dictynnar. Moist meadows; July and August. Very 



dark-coloured ones on the mountains. 



8. Athalitf. Common in meadows ; varies very much in co- 



lour and markings, as well as in becoming very dark 

 on the mountains. 



9. Parthenifl. With the last ; very common in August and 



September. 



10. Lucin«. Meadows in spring; not rare. 



Argy'nnis. 



(Aphirape. Valais in July; very rare.) 



11. Selena. Not rare about Buren (a town five leagues from 



Berne) and Soleure ; very common in many parts of 

 Italian Switzerland. 



12. Euphrosyn<?. Frequent in spring in thinly wooded fo- 



rests. In Alpine stations its flight commences in July 

 and August. 



13. Dirt. Common in May and August, in meadows, paths, 



&c. 



14. Pales. Common on High Alps; Grimsel, Gemmi, &c. ; 



with many variations, particularly on the under side. 

 On the Cherbenon Alp in the Valais is a very dark 

 variety, with a play of blue colour on the upper side. 

 (The green variety, which is Hiibner's Tsis, is found, 

 but rarely, on the Grimsel in July.) 



1 5. Trio. In moist meadows in July. Not frequent. 



16. Thor?. This rare species I (i. e. Professor Meisner) 



found, for the first time, in June, 1 804-, in the Suren- 

 enthal, above Engelberg, at which time it was not 

 anywhere described, and was considered as quite new. 

 In 1809, I found females in the same locality, and am 

 not aware of its having been since met with in Switzer- 

 land ; it has been lately taken on the Alps of the Tyrol. 

 (This was published in October, 1817; and Boisduval 

 says it has since become more common in some spots 

 of Switzerland.) 



17. Daphne. In the Valais, about Saillon, Sierre, &c. ; 



June and July ; rather frequent. 



18. Amathusirt. On lower mountains and Alpine pastures, 



especially where shaded by shrubs or leafy woods. (In 

 the original, " laubwaldungen," leaf woods or forests ; 

 that is, of beech, oak, &c, to distinguish them from the 

 more common fir forests. Not only does the descrip- 

 tion of shade and general vegetation of the beech forest
