the generic types is necessary to establish the relationships of the 

 various Agrotid genera. Our N. American species listed by Hampson 

 under Triphacna will fall into Rynchayrotis Sm. as the type of this 

 genus was distinctly stated by Smith in his Agrotid revision (p. 9) to 

 be cupida Grt. For further references regarding the types of Xuctidt 

 and Triphacna we would refer the reader to a paper by Grote in Proc. 

 Am. Phil. Soc. Vol. XLI, 1902. 

 Mythimna Ochs. (1816). 



The type was first specified by Duponchel in 1829 as albipuncta Fabr., 

 but Hiibner in 1822 (Verz. p. 239) had already restricted the genus to 

 oxalina Hbn. and acctosellac Schiff., a fact which was overlooked by 

 all subsequent authors. Hampson's usage with oxalina as type would 

 be therefore correct. Alcsogona Bdv., the type of which was specified 

 by Guenee (1852) as acetosella Schiff., will fall as a synonym. 



Eurois Hbn. (1822). 



Type specified by Grote (1874, Buff. Bull. II, 12) as occulta L. and 

 the genus will probably fall before Lycophotia Him., the type of which 

 Hampson specifies as porphyria Schiff. Hampson's usage of Eurois 

 with prasina L. as type is incorrect. Aplecta Gn. (placed in the syn- 

 onymy by Hampson) cannot be used in its place as the type was desig- 

 nated by Guenee (1852) as ncbulosa Hfn., a hairy-eyed species placed 

 by Hampson in Polia. Matnta Grt. (type tencbrifera Wlk.) must ap- 

 parently be used. 



Polia Ochs. (1816). 



The type of the genus was designated by Curtis in 1828 as ncbulosa 

 Hfn. Hampson's usage of the genus is therefore correct. Duponchel's 

 fixation in 1829 of the type as compta Esp. (conciniia Hbn.) is ante- 

 dated by Curtis' action. 



Mamestra Ochs. (1816). 



The type was designated by Duponchel in 1829 as brassicac L. Grote, 

 however, justly contends that Hiibner's restriction of the genus in the 

 J'crzcichniss (p. 214) rendered Duponchel's action ultra vires and speci- 

 fies the type as pisi L., which would cause Mamestra to fall as a syno- 

 nym of Polia. 



Xylomyges Gn. (1852). 



Grote specified the type of the genus in 1874 as conspicillaris Schiff. 

 and Guenee's name will therefore replace Xylotnatiia I lamp. 



Hadena Schr. (1S02). 



The type of this genus has been variously chosen by Duponchel, 

 Curtis, Westwood and Guenee, but none of the authors lias mentionril 

 one of the original specimens as type. Grote (Ent. Rec. VI, 78, 1895) 

 designates the type as cucubali Schiff. and makes Dianthoccia Bdv. 

 sMionymous. We would refer students to this paper and to the paper
