indiatinct, consisting of an oblique, regularly curved streak from near 

 tlie base of the inner margin, meeting a very faint central fascia, and 

 tbereby enclosing a slightly paler blotch, which, from an indentation in 

 the central fascia, has a double apex. 



It may best be distinguished from the allied species by its dull 

 brown colour ^nA. j>f^ile greyisli-hroion hind-wings. It flies in September 

 and October among alder, upon which its larva feeds, and is not un- 

 common in fenny and marshy districts. 



'Pcedisca Solandriana, Linn. — This abundant species is so well 

 known, that a desci'iptiou of its numerous and striking varieties seems 

 unnecessary. It may generally be distinguished from the two pre- 

 ceding s]3ecies by its grey hind-wings with darker apex, and from 

 semifuscana also by the greater breadth of its fore-wings. 



The larva feeds on birch and hazel, and the perfect insect flies, 

 like its congeners, at dusk, and is also readily beaten out of hedges in 

 the afternoon during July and August. 



Pcedisca oplithalmicana, Hiib. — A very distinct species, said to 

 feed upon aspen (^Popiilus tremula). 



Ciitoptria Scopoliana, Wilk. {non Haw.). — Professor Zeller tells 

 me that this is HolienwartJiiana of G-erman authors, but of this I must 

 say more presently, as there is great confusion in the names of this 

 and the two next species. 



Haworth's description of Tortrix cnna (p. 456) — " "Wings greyish- 

 " white, somewhat clouded ivith fulvous, with oblique costal streaks 

 " silvered over toicards the tips'^ * * * "Very like the preceding 

 " (pupiUana =fidvana, Steph.) but different in colour, costal strigce 

 " more silvery, ocellus more silvery and continuous " — certainly refers to 

 this species : it can be no other. Stephens' description is a copy of 

 this, and Wood's fig. 987, though not very good, is evidently intended 

 for it — witness the longitudinal streaks. 



Gruenee's carduana — " Head and thorax fulvous, anterior winga 

 " whitish, fulvous at the base, with longitudinal lines and clouds, and 

 " a silvery speculum with black lines. Posterior wings cinereous, 

 "paler in the middle in both sexes " — is also this species, and a far 

 better description of it ; but Haworth's description being fully recog- 

 nisable, I think it only just to restore his name. The synonymy of 

 this species will therefore be 



{Catoptria, Gn.) cana, Haw., Steph., "Wood (987). 

 carduana, Gn. 

 Scopoliana, Wilk. 

 .'' Sohenwartliiana, Schiff., Tr., H.-S. 



This species seems to be exclusively attached to thistles.
