Head, face, and palpi white. Antenne: white, annulated with dark 
fuscous. Anterior wings ochreous-brown, with the inner margin white, 
interrupted beyond the middle by a dark brown, nearly perpendicularly

greyish-brown. Posterior wings grey, with paler cilia. 
Common in the south of Hngland, but more abundant in the 
north; frequenting gardens and hedges in June and July. Mr.

cherry.
