THE ENTOMOLOGIST. 75 



Ypsipetes ehitaria. Another variable species : when fed 

 upon whimberry or cowberry it is a most distinct-looking 

 insect, often with the white patches placed in a triangle, one 

 on the disk, one on the hind margin, and the usual one : no 

 band. 



Y. irapluviata and L. caesiata vary more in colour than in 

 form of markings : 1 have them from very light to almost 

 black. A variety of the latter, which I call " nigristiaria," 

 with deep blackish brown central band, is common on the 

 Lancashire moors, whilst Moel Vamma (Welch) specimens 

 rarely show the broad band darker than the other parts of the 

 wing. 



Oporabia dilutata. Varies in some woods, and has abro 

 dark band, whilst in others it scarcely varies at all. 



O. filigrammaria. Varies much in size. I have it from 

 very light to very dark. 



Lobophora lobulata. Is usually a plain unvarying species, 

 but I have six fine varieties, by which I see that in Scotland 

 it is sometimes a very handsome insect, with a broad very 

 dark band across its wings. 



Camptogramma bilineata. By taking a great number of 

 specimens, over a series of years, I have secured seven good 

 varieties. 



Melanippe hastaria. One specimen before me reminds me 

 of a species not yet recorded as British, and another exceeds 

 its fellow quite one-fourth of an inch in expanse, and has less 

 black upon it. 



M. tristata. Of this unvarying species I have several 

 striking forms ; one in which the central band is broken on 

 one side slightly, and on the other very much, so as scarcely 

 to form a band ; and one in which the central bands are 

 broken, and the outer margins rayed inwards. Scotch 

 specimens of this species are tinged with ochreous. 



Emmelesia rivularia. I have one small dark brown speci- 

 men ; one large dark brown female, without any white striae 

 or bands; several dark, with very narrow light fascia. 



E. bifasciaria. One with a dark mark on the costa, which, 

 joining the central fascia, and destroying the first light fascia, 

 makes it a unifasciaria of Haworth ? 



Cabera pusaria. Two specimens having only two dark 

 striai across the wing; one having four; several undoubted
