rgo LEPIDOPTERA. 



By far the most widely distributed species in the genns, but 

 hardly ever plentiful except in very large woods in the south 

 of England — such as the New Forest. Not uncommon in 

 woods, and in the better wooded districts, throughout the 

 South of England from Kent to Devon ; also in the Eastern, 

 Midland and Western Counties to Lincolnshire, Derbyshire, 

 Herefordshire, and Pembrokeshire ; and in several localities in 

 Yorkshire. In Scotland it has been found in Ayrshire, and, 

 rather commonly, at Moncrieff Hill, Perth. In Ireland widely 

 distributed ; at Howtli, near Dublin, in Wicklow, Mayo, 

 Galway, Down, and near Lough Swilly, Londonderry. Abroad 

 its distribution appears to be rather local — in France, Belgium 

 and Western Germany, but there is a probability that it has 

 been in some districts confused, as with us, with closely allied 

 species. 



4. N. centonalis, Hilh. — Expanse \ incli. Fore wings 

 short, white, with slender brown transverse lines or light 

 brown bands, and a row of raised ])rown tufts of scales ; hind 

 wings whitish. 



Antennae rather short, slender, but abundantly furnished 

 with bristles, in two rows, in the male ; simple in the female ; 

 whitish, with a broad, flattened tuft of white scales at the 

 base ; head white, with a dense mass of flattened white scales 

 between the antenna? ; palpi long, brownish-white ; thorax 

 and abdomen whitish. Fore wings short and broad, with 

 margins very slightly curved, apex rounded, hind margin 

 rather oblique, white ; the costa clouded at the base, and 

 spotted beyond it, with fawn-colour, the spots in the middle 

 portion being minute, and those towards the apex rather 

 large ; in the discal cell is a row of three tufts of raised light 

 brown scales ; first line curved but very indistinct, existing 

 mainly as a series of three brown dots, one of which is the first 

 tuft of raised scales, but it is generally edged with fawn- 

 coloured clouds ; second line dark brown, straighter but 

 sinuous, and in some degree parallel with the hind margin, it
