moths of the earlier genera of Noctuites. 385 



Tetrapyrgia pectinata. 



Spcelotis pectinata, Walker, Lep. Het., Suppl., 8, 



p. 707 (1865). 

 Elegarda orthosioides, Walker, 1. c., p. 712. 



Moreton Bay. 



A rather variable species. 



SEMIOPHORA, Steph. 



Very similar to Amathes (Graphiphora, auct.), but the 

 males with antennae strongly pectinated, as in the genus 

 Eucoptocnemis ; several of the species hitherto referred 

 to Agrotis, Graphiphora, and Tceniocampa belong rightly 

 to this genus. 



Semiophora elimata. 



Graphiphora elimata, Guenee, Noct., i., p. 333, n. 556 



(1852). 



The Agrotis dilucida of Morrison is indistinguishable 

 from this species. 



MAMESTKA, Ochs. 



The bulk of the species hitherto referred to Apamea 

 and Hadena are structurally identical with Mamestra ; 

 the same pattern also runs through the species.* 



1. Mamestra dissimilis, Enoch. 



I cannot distinguish the M . atlantica of Grote from 

 this species. 



2. Mamestra thalassina, Hiifn. 

 M. nevadce of Grote is this species. 



3. Mamestra cristifeva. 



Acronycta cristifera, Walker, Lep. Het., xv., p. 1654 



(1858). 



This is the Mamestra lubens of Grote. 



* The lashed or smooth eyes of species otherwise closely allied 

 do not in my opinion constitute a safe generic character.
