54 THE GENERA OF BRITISH MOTHS. 
It feeds on CochleariaArmoracea, The perfect insect appears in June, but was formerly considered rare, though 
widely-dispersed, having been taken at Darenth Wood, in Norfolk, and as far north as Lanark. More recently it 
has been taken in some abundance at Brighton, at Hull, and other places. 
E. Nebulosa (the Gray Arches, No. 15) is one of the largest of the new group, sometimes measuring near 
two and a-quarter inches across the expanded wings. It is a widely-dispersed and common species, ain found 
sitting on the trunks of trees in June. The Caterpillar (No. 16) feeds on Verbascum Thapsus. 
E. Occulta (the Great Brocade, No. 16) is the largest of the group, and, indeed, perhaps of the whole of the 
extensive family of the Noctwidw, sometimes measuring nearly two and a-half inches across the wings. The Cater- 
pillar (No. 17) feeds on Lettuce, Dandelion, etc., in May, the Moth appearing in July. It may be considered a rare 
insect, though it has been taken at Birkenhead, at Edinburgh, in the Lake District, in Epping Forest, at Dover, and 
other places. 
The other species are E, Advena (the Pale Shining Brown) and EZ. Tincta (the Silvery Arches) ; the first, an 
inconspicuous insect of nearly uniform pale brown, the markings being very obscure ; the second is very handsome 
in appearance and midway between Occulta and Nebulosa, and nearly as large. It is rare, but has occurred in 
several localities, as Plymouth, Worcester, Birch Wood, etc., etc.
