Bactra uliginosana, AVestw. — This is Lorquiniana, Dup. (1838) ; 

 and that name, being anterior to AVestwood's, must be adopted. Ac- 

 cording to M. Jourdheuille's calendar, the larva feeds on Ly thrum 

 salicaria. 



Bactra lanceolana, Hiibu. — This species varies so greatly in size 

 and markings, that there is a constant tendency to describe its different 

 forms as distinct species. JSfigrovittana of Stephens is one of these 

 forms, and is still considered distinct by some Entomologists. It is 

 not confined to Scotland ; I used to take it, in company with other 

 forms of lanceolana, in marshy meadows near Haslemere. I think it 

 is usually a female variation. 



Another form (very large) is found on the coast in salt marshes, 

 and is also thought by some to be a distinct species. It, however, 

 cannot be separated from some of the specimens of lanceolana from 

 Eanworth fen, and I suspect that this species attains a larger size in 

 very wet situations. On the other hand, specimens of the second 

 brood are sometimes as small as Anchylopera comptana, and pale 

 cinereous mth hardly a trace of markings, so that they can hardly be 

 recognised as this species. 



Bactra furfur ana, Haw. — A very widely distributed species, since 

 it is found also in JS^orth America, but smaller and j)aler than with us, 

 as also is the case in Germany. 



Argyrotoza Conwayana, Fab. — In M. Jourdheuille's calendar the 

 larva is stated to feed in berries of privet and barberry, and to enter 

 the pupa state outside under a white web. It has also been bred from 

 the seeds of the ash. 



Dictyopteryx contaminana, Hiibn. — Prof. Zeller says that the larva 

 feeds also on sloe, and in Sorbus blossoms. Mr. Doubleday finds it 

 abundantly on cherry, and thinks that it will feed on various other 

 trees. 



Dictyopteryx Shepherdana, Steph. — Not at nil rare now ; indeed, 

 rather common among Spircea ulmaria in the fens of Norfolk and 

 Cambridgeshire. It feeds, with Tortrix cosfana and Paramesia asper- 

 sana, in the tops of the Spiraea, twisting the leaves together. In bred 

 specimens, the "button" tuft of scales is very distinct on the fore- 

 wings. "Wilkinson seems to have overlooked this ; hence he has placed 

 it here instead of with its close allies Peronea and Paramesia. 



Dictyopteryx Loejlingiana, Linn.
