No Noctua known to me varies more than the foregoing. To this 

 cause in part is due that it is so surrounded with synonyms, and a 

 further reason of the confusion is that authors mostly made their de- 

 scriptions from very worn specimens. First, Duponchel says in the 

 description of his Gronlandica, that he quite thinks it agrees with one 

 of Lefebvre's species, but Lefebvre's original specimen is so bad that 

 from it nothing can be decided. Exulis, Lefiebvre, was already, by 

 other authors, with the greatest propriety, placed as the male of gelata. 

 Duponchel described this species very recognizably as Gronlandica, 

 and indeed in the same year, 1836, in which it was published as exulis 

 and gelata, of Lefebvre. But as Duponchel already, in his Gronlandica, 

 mentions the exulis and gelata of Lefebvre, so must the latter name 

 necessarily appear to be the earlier, and therefore the name exulis, 

 given to the male, is chosen for the species. The mere Catalogue 

 name borea, Boisd., is of no value ; but the original in Boisduval's 

 collection proves to be perfectly identical with exulis. Dr. Herrich- 

 Schaffer places this species under two genera, Polia and Neuria, as 

 gelata, Gronlandica, borea, and cervina. These prove to be the best of 

 the types of Messrs. Kaden and Pogge apportioned to the descriptions 

 of Herrich-SchafFer. So also the Mamestra cervina, Germar, brought 

 from Iceland by Kaden, is only exulis. Eversmann described in the 

 "Bulletin de Moscou" for 1842, another Noctua as cervina, which
