l28 CATALOGUE OF MOTHS. 



Meyrick says * ' the variety of the $ with a posterior costal 

 mark has long heen regarded as a distinct species under the 

 name of seppella ; hut the two forms are connected hy gradual 

 transitions." Mr. Bankes also believes that seppella, Fabr., is 

 merely a variety of aruncella, Scop. I use the name seppella 

 as Stainton did so, and also because the form so-called appears 

 to be the only one known in this district. The "Manual" 

 marks it as occurring regularly both at Newcastle-on-Tyne and 

 at Darlington. Mr. Sang took it at Castle Eden Dene as long 

 ago as 1853 ; on the railway banks, Darlington, in 1872, and at 

 Hartlepool in 1889 ; Mr. "Backhouse took it at St. John's; and 

 Mr. Gardner has taken it on the Hartlepool sand banks, 

 especially common on the spiny rose.

 Eriocephala aureatella. Meyr. Hdbk. Brit. Lep., p. 806. 



This is given in the "Manual " as occurring at Newcastle- 

 on-Tyne regularly and at Darlington. Mr. Finlay found it 

 scarce at Longwitton Garden House. Mr. Sang took it at 

 "Wolsingham in June, 1877 and 1878. I have no other records 

 than these. It is a "local" species, generally occurring in 

 woods.

Generally a common species in woods. I have, however, no

 gives it as occurring regularly both at Newcastle-on-Tyne and 

 Darlington.

Micropteryx purpurella. Staint. Man., vol. ii., p. 303.
