 the apex. 



Var. 2, 5 . Stigma pale testaceous. Bred by W. H. B. Fletcher 

 from Elachista tceniatella, Staiut. 



This species closely resembles vitripennis, Hal., and 

 the males are bard to distinguish, except by the smoother 

 metathorax and larger size of the latter. Eeinhard, in 

 his ' Bestimmungs-Tabelle,' distinguishes the two species

 Giienee ; a ? , Sept. 15th, by Bignell from Sym/ethis 

 oxyacantlielhi, L. If the synonym from Eatzeburg be 

 correct, it is also a parasite of Hypo7iomeuta jyadelhis, Lc, 

 bred by Kirchner. It is abundant in a wood close to my 

 house, at Nunton, Salisbury, and is taken at Maldon by 

 Fitch. Cocoons white.
