A northern species, in few collections: my specimens were 
taken on the coast near Belfast in September. ; 
4. Dalella, Sta. Cat. p. 11 (1849).—vittella, Hib. Tin. 164. Alis 
anticis griseis, griseo-fusco marmoratis, postice albido-squamatis, trian- 
gulis tribus dorsi dilutioribus, spatiis interjectis saturate griseo-fuscis, 
maculis duabus coste pone medium fuscis, apice marginis postici nigro- 
punctato. Exp. al. 10 lin. 
Head, face, and palpi dark greyish-fuscous, Antenne dark fuscous. 
Anterior wings grey, marbled with greyish-fuscous, posteriorly with 
some whitish scales; on the inner margin are three pale triangles, the 
first near the base very small, the second in the middle reaching to the 
fold, and sometimes produced posteriorly beyond it, and the third be- 
yond the middle reaching beyond the fold; the spaces between these 
triangular marks are dark greyish-fuscous; on the costa beyond the 
middle are two fuscous spots; towards the apex of the hinder margin 
are two or three black spots; cilia greyish-fuscous, with two darker 
lines. Posterior wings grey, with paler cilia. 
Not uncommon in the north of England and Scotland, in Sep- 
tember. Many specimens have been takeri near Huddersfield by 
the Rev. J. Johnson.
