HABITAT. Wisconsin; "North America"; Colorado. 



The types of the Walker and Grote names are in the British Mu- 

 seum, and all refer to the same species. Mr. Grote first compared his 

 species to modica and afterward placed it next to fractilinea, of which 

 I placed it as a variety in my list. It resembles exactly that species 

 with all the red taken out. I have separated it here tentatively and 

 for convenience in giving the synonymy. 



H. fractilinea Grt.* 



1874. Grt., Can. Ent., vi, 15, Hadena. 



vulvivaga Morr. 

 1874. Morr., Proc. Bost. Soc. N. H., xvn, 144, Hadena. 



HABITAT. Canada, in August; New York, in August; Illinois; Ver- 

 mont; Wisconsin; Nebraska; Colorada; New Mexico. 



Mr. Morrison's type is in the Tepper collection. Mr. Grote's type I 

 have not seen. It does not seem to be in the British Museum, but I 

 may have overlooked it. I have, however, seen a number of specimens 

 named by Mr. Grote, and there is no doubt that Mr. Morrison's species 

 is the same. 



H. misera Grt.* 



1881. Grt., Bull. Geol. Surv., vi, 582, Hadena. 

 HABITAT. Illinois; New York, in August; Wisconsin. 

 The type is with Mr. Neumoegen.

1889. Butler, Trans. Ent. Soc. Lond., 386= Mamestra ferrea. 



HABITAT. Hudson Bay Territory; Colorado. 



Mr. Butler is in error in referring this species to Mamestra stricta 

 Wlk., = ferrea Grt. It is not a Mamestra at all, but a Hadena, and the 

 type, though a poor specimen and badly rubbed, is like an insect I 

 have had from Colorado, collected by Bruce. It is a good species. 



H. minuscula Morr. 



1874. Morr., Proc. Bost. Soc. N. H., xyn, 147, Orthosia. 



1875. Grt., Proc. Ac. Nat. Sci. Phil., 1875, 425, Parastichtis.

1875. Morr , Proc. Ac. Nat. Sci. Phil., 1875, 431, Hadena. 



HABITAT. Canada, in September; Massachusetts, in August and 

 September; Maine; New Hampshire. 

 The type is in the Tepper collection.
