THE YOUNG NATURALIST. 



grey." Staudinger says " Forewings ashy, black, fuscous, white 

 and ochreous, more minutely marbled, wavy in the middle." They 

 do not agree very much, 

 v. unicolorata, Str. Cat. Wings nearly unicolourous, white, grey, 

 fuscous or black. It seems very absurd to give all these the same 

 name. 



These two species are so closely allied that it is no wonder they are 

 mixed in so many collections. 

 SufTumata 



v. Piceata, Haw. The entire wing of the same colour as the central 

 band. A very distinct form occurs at Deal, for specimens of which 

 I am indebted to Mr. Sidney Webb. In it the band is darker 

 and better denned than in the type. Mr. Webb tells me it occurs 

 regularly, but sparingly, with the normal form. A similar form, as 

 far as my memory serves me, is in Mr. Porritt's collection, taken 

 by himself at Huddersfield. 



Reticulata 



Silaceata 



Newman figures six distinct forms of this insect, the central band 

 varying, from one with a broad uninterrupted fascia, to another 

 in which it is separated into three distinct portions. This, I think, 

 is Haworth's Insulata. But none of them are distinct or constant 

 enough to merit distinguishing names. 



Prunata 



Testata 



Populata 



A form called Musanaria, Prr., occurs in Silesia and on the moun- 

 tains of Bavaria. It may occur in Britain but I have never heard 

 of it. It is darker and nearly unicolourous. 



Pulvata 



Pyraliata 



Dotata 

 Pelukga 



Comitata 

 Etjbolia 



Cervinata 



Mensuraria 



It would appear this species should be called Limitata Sc., that 

 name being given in 1763 and Mensuraria not till 1776. 

 Palumbaria
