miicli paler and clearer variety occurs, but is rare. It is dull pale 

 ochreous with a slight olive tinge, and the markings pale olive-brown. 

 I am not aware that this variety has been found in Britain. 



Wilkinson is certainly in error in saying that this species occurs 

 generally throughout the country, and is not uncommon. It is usually 

 rare in this country, but Mr. Stainton tells me that in July, 1851, 

 he found it in abundance under elm. Mr. Machin tells me that he 

 has collected hundreds of Tortrix larvas in one of its few localities, 

 but has bred only three or four of this species from them. These 

 fed on birch and willow. I think that Wilkinson's mistake has 

 arisen from the fact that fine males of T. rosana have sometimes been 

 mistaken for this species : rosana may always be known by the yellow 

 or reddish colour of the apex of its hind- wings, which in difersana 

 are entirely fuscous. 



Xiozotcenia sorhiana, Hlibn. — Wocke divides Tortrix and Lozofwnia 

 into five or six genera, mixing with them some suificiently startling 

 species from other groups, but he does not do violence to our judg- 

 ment so far as to separate them into ^iiiiinct families. 



Lozotcenia mtisculana, Hlibn. — From the habits and general 

 appearance of this species, I think it far more appi'opriately placed 

 here than in the genus G)iephasia. 



LozotcBfiia latiorana, Stainton. — Mr. Doubleday sinks this, in his 

 List, as a variety of costana, Pab., and in this I am convinced that he 

 is correct. In the few specimens which I have been able to examine, 

 the form of wings is exactly as in costana, and precisely the markings 

 of that species may be faintly traced in the male. I cannot see any 

 difference in the satiny gloss of the two forms. 



Lozotcenia semialbana, Gn. — Professor Zeller tells mo that he 

 finds this species on beech. 



Lozotcenia costana, Fab. — In some parts of the country specimens 

 are found, not uncommonly, in which the whole of the fore-wings is 

 sviffused with the fuscous or reddish colour of the fascia. In the 

 Norfolk fens, however, where the insect is exceedingly abundant, 

 this variety seems very rare. I have received it from Birmingham 

 and York. 



Lozotcenia unifasciana, Dup. 



Lozotcsnia fulvana, ^ohi^.? , Wilk. — Mr. Doubleday, in his List, 

 correctly substitutes pyrasirana, Hiibn., but this is superseded by Dr. 

 Wocke in favour of Podana, Scopoli (' Entomologia Carniolica,' 17G3), 

 a far earlier name. Professor Zeller confirms this correction.
