206 Swiss Diurnal Lepidoptera* 



as containing in a slightly condensed form those of his observ- 

 ations which appear to be interesting; and noticing all the 

 varieties which are still occasionally met with, neglecting such 

 only as may have presented themselves in a solitary indivi- 

 dual. This list being essentially that of Meisner, the whole 

 must be considered as his, except such species or notices as 

 are included in parentheses. 



The names are invariably those of Ochsenheimer ; and as 

 that author has made observations, in the same work, on a few 

 of the species in this list, they are incorporated with the new 

 matter, always with acknowledgment. I thought at first of 

 rearranging the species, to adapt them to works better known 

 in England ; but, more especially as Ochsenheimer is usually 

 cited by Mr. Stephens in his Systematic Catalogue^ I have 

 since determined to leave the list as I found it. Mr. Bree's 

 term, " Swiss papilios," makes me presume that the list de- 

 manded was merely that of the " Diurna," and to them I 

 have accordingly confined myself; in fact, I scarcely know 

 how I could have completed it satisfactorily for the Lepidop- 

 tera in general. Meisner's catalogue breaks off abruptly, 

 with an unaccomplished " to be continued," at the genus Eu- 

 prepia ; and I cannot learn that any other extensive list is 

 extant. It is, however, to be hoped, that something of the 

 kind will soon be given to the public, a circular having been 

 addressed to the members of the Helvetic Society of Natural 

 Sciences, requesting them to furnish the most ample zoological 

 lists, with observations, for the purpose of preparing a Fauna 

 Helvetica. The Alpine " Nocturna" are, certainly, and will 

 long remain, very imperfectly known ; much, however, may 

 be expected from the perseverance of the zealous and success- 

 ful M. Anderegg of Gampsen, near Brieg, in the Valais 

 (that El Dorado for a naturalist) ; but whether or not his two 

 new species, A 7 6ctua helvetlna and N. cataleuca, published 

 by Boisduval in the second volume of the Annates of the 

 French Entomological Society, will stand their ground, is 

 somewhat questionable.
