in Cumberland. I could scarcely persuade myself it was the same 

 species. I would be glad to see authentic specimens from various 

 localities. 



SOOTOSIA 



Dubitata 



v. Cinerata, Steph. Smaller, paler, and without the reddish tinge of 

 the type. 

 Vetulata 

 Rhamnata 

 Certata 

 Undulata 



ClDAMA 



Psittacata (Schiff, 1776.) Called siterata, Hufn., 1769, in Staudinger. 



Miata 



Picata 



Corylata 



v. albocrenata, Curt. The band entirely wanting, and the forewings 

 white with a few darker irregular markings. An aberration only, 

 and not one that should have a distinctive name. It is not recog- 

 nised by Dr. Staudinger. 



Sagittata 



Russata 



This variable species has borne nearly a dozen names, but the forms 

 run so much into each other that they scarcely deserve a distinctive 

 name, although the extreme varieties appear very distinct. A com- 

 mon North of England form has the central part of the fore- wing 

 filled in with orange-red. This is the v. Comma-notata of Haworth. 

 A light coloured form, with the centre of the wing nearly all white, 

 is the Centum-notata of Schultz. Another, with this portion 

 smoky-brown, is the Perfuscata of Haworth. A very beautiful 

 form, brown with distinct white lines, occurs in the Isle of Arran, 

 but I have seen too few to know if it is at all constant. If it be 

 so it is as deserving a distinctive name as any of the others. 

 Immanata 



Equally variable with the last, and the varieties equally connected by 

 transition forms. Several have been named. 



v. Thingvattata, Sdr. Cat. Wings white, with base and central fas- 

 cia black or fuscous. 



v. Marmorata, Haw. Newman figures this variety (see fig, 2), and 

 describes it, " The median area of the fore-wings is pale whitish
