THE CANADIAN ENTOMOLOGIST. 211 



i84r. Guen., Noct. Eur. Index xMeth. Ann. Soc. Ent., Fr,, I. Ser., Tom. 

 lo : ophiogramma, didynia, unanimis, geoina. Excejit the first, 

 which goes to Oligia, Lederer's section C, this restriction gives us 

 species belonging to Lederer's section B of Hadena, Led., nee 

 Schrank. Hiibn. does not use Apamea. Further citations have no 

 bearing on the subject of the type, which may be accordingly taken 

 as didyma. 



The species heretofore classed under Hadena, Led., fall to 

 Xylena ( == Xyloj^hasia), He/ioscota, Apamea and Oiigia. The 

 European type Ilanis ochroleuca is not recognized as American. 



Lupcriiia. 



1829. Boisd., Europ. Lep. Index Meth., 77: Dumerilii, argillacea, testacea, 

 contribulis, cespitis. One of the above must be type. The use of 

 this term for vire/is, etc., by Lederer is therefore erroneous. For 

 Liiperiiia, Led., nee Boisd., type vircns, the term Ledereria, Grote, 

 1874, should be used. Testacea may be taken as type, taking with 

 it Duiiierilii. Argillacea is a var. of Hadena ( Diajithoccia) luteago. 

 Cespitis is apparently type of Tliolera ; contribulis is apocryphal. 

 This generic term, as previously suspected by me, must be used 

 instead of Apamea, Led., nee Ochs. The subsequent enlargements 

 oi Luperina by Bcisduval (1840) and Guene'e (1841) have no bear- 

 ing on the question of type. In literature of the North American 

 Noctuid Fauna this name has been seemingly wrongly applied. 

 The existence in our North American fauna of species congeneric 

 with Luperina testacea or Ledereria virens has not been made out 

 as yet satisfactorily. In all cases, to insure the "scientific" applica- 

 tion of the generic name, the type species as here given must be 

 studied and compared with American material. It is very necessary 

 at the moment that this should be done before the issue of a new 

 Catalogue. For this reason I jjublish the literary evidence so that 

 it may be looked into and, if possible, contradicted or corrected. I 

 had brought the classification of the North American Noctuids into 

 general harmony with Lederer's, so far as structure was concerned. 

 I could not always adopt hi«s generic names, because he had made 

 no literary study of the subject, had taken at times the first name 

 which came to hand in fact, and had repudiated the authority of the 

 Verzeichniss, now acknowledged by almost all writers in England
