46 LLOYD'S NATURAL HISTORY. 



markings, the claviform stigma only being usually indistinct 

 or obsolete. The hind-wings are brown or grey. 



The larvae, which feed on low plants, and hide themselves 

 under leaves during the daytime, as is the usual habit in this 

 Sub-family, are stout and cylindrical, with a small head, and 

 very distinct lines. 



The name Noctua has been applied to this genus by many 

 recent authors, but in any case wrongly. It is true that 

 Schrank indicated the Agrotince. as the types of Noctua, but 

 Latreille afterwards indicated Triphana fimbria (Linn.) 

 (antea, p. 43) as the type ; and this would stand as such, 

 but that Poda, Cuvier, and Lamarck had already indicated 

 another species as the type. 



The type of Graphiphora is G. c.-nigrum (Linn.), wrongly 

 called by Hiibner and others G. gothica (Linn.), which is a 

 different species. Another of the rather numerous species of 

 the genus is here figured.
