synonymy of the genera of Noctuites. 673 



MAMESTRA, Ochs. 



1. Mamestra binotata. 



Mamestra binotata, Walker, Lep. Het., Suppl., 2, 



p. 663 (1865). 



Hadena extersa, Walker, 1. c., 3, p. 728 (1865). 

 H. curvata, Grote pavice, Behr. (see Grote, Check 



List, p. 27, n.450). 

 United States. Coll. B. M. 



2. Mamestra inducta. 



Mamestra inducta, Walker, Lep. Het., ix., p. 236, n. 32 

 (1856). 



M. septentrionalis, Walker, 1. c., Suppl., 2, p. 660 

 (1865). 



Venezuela and United States. Coll. B. M. 



This is labelled M. lycarum, H.-Sch., on Grote' s 

 specimens. 



The Mamestra insulsa of Walker is an Agrotis allied to 

 A. albipennis (males, having white secondaries, stood 

 without a name in the Grote collection) : M. expidsa, 

 Walker, is another closely allied species. 



Mamestra nitida, Walker, is a distorted female of 

 Agrotis spina, Guen., without secondaries. 



Mamestra punctig era $ , Walk., is the male of Agrotis 

 pastoralis 2 , Grote. 



Mr. Barrett pointed out to me that Walker's Mamestra 

 cotifigurata, from Mexico, is a slight variety of M". brassicce. 



HADENA (typical), Guen. 



I only regard this as a group of Mamestra. 



Hadena albifusa, Walk., represents H. trifolii in the 

 United States, and may not be constantly different ; in 

 our examples the primaries are far less uniformly 

 coloured, the usual markings being denned upon a paler 

 ground colour. 



The following species referred to Hadena are synony- 

 mous : 



Hadena detracta, Walk. (Mamestra claviplena, Grote), 

 which appears to me to be a Pachnobia. 



Hadena sputatrir, Grote Apamea ? insignata, Walk.
