a broad pale stripe running within the costa, nearly half along the wing. The anterior stigma is nearly 
triangular, and the posterior one is reniform ; the space before, between, and behind which is black, or dark brown. 
The teliform stigma is very large, and extends to the base of the wing, but is interrupted by two pale, oblique, 
divaricating stripes; the centre of the spaces between the veins, behind and beyond the outer stigma, is marked 
by dusky patches, and the apical margin of the wing is very irregularly brown ; the costa itself is marked with 
numerous blackish dots. The posterior margin of the wing is also marked with a long dusky streak. The 
hind wings are pale, with a slight central lunule and a dusky border. The abdomen is pale, but rather fulvous 
towards the tip. 
Found near London, and Barnstaple, in Devonshire, by W. Raddon, Esq., the celebrated engraver, as well 
as in Norfolk.

This species is extremely variable in its colour as well as markings ; it measures from lJ to 14 inches in the 
expansion of the fore wings, which, in the more ordinary character of the species, are of a nearly uniform pale 
brownish buff, without irrorations or any other than the ordinary markings, namely an indistinct basal, wavy, 
pale line, and another similar and very slender, but edged with black on each side, to the outer side of which the 
teliform stigma is attached, which is very distinct, oblong, and black ; the other stigmata are generally dark 
and edged with black, but sometimes nearly obsolete ; beyond the outer one is a much curved fascia, formed of 
very slender blackish arches more or less distinct, and sometimes edged with whitish on the outside ; a very irregu- 
larly angulated pale line runs near the margin of the wing, which is rather darker ; the costa is also marked with 
several pairs of dusky and light dots, and is occasionally tinged with purple; the head and thorax are of the same 
colour as the fore wings, the latter marked with a rather broad angulated mark. The hind wings are nearly 
white in the male, except at the outer angle, which is tinged with brown, as well as the veins. In the female 
they are brown. 
The variety picea, of Haworth, has the fore wings of a pitchy black colour, without strige, and with the 
two basal stigmata oblong, and the outer one round and black. The hind wings brown. 
The Agrotis plaga of Stephens, from Whittlesea Mere, is most probably another variety of this species, in 
which the ordinary stigmata and strigze are obliterated, the place of the former occupied by a “‘ very faint brown 
dash ;” whilst the teliform stigma is distinct and elongated into “a stout, deep, black longitudinal dash towards 
the inner margin, and above one third the length of the wing.” 
The ordinary varieties of this species are very common. The larva precisely resembles those of A. corticea 
and cinerea ; it is found in July under stones and at the roots of grass ; it is of a dark brown colour, and glossy, 
with a pale dorsal line and faint dots; it feeds on groundsel.

This very rare species measures only from 14 to 14 inch in the expansion of the fore wings, which are pale 
hoary or whitish gray ; the costa slightly clouded with fuscous, with a cloud of the same hue at the base of the 
wings, divided from the teliform stigma by a very obscure transverse waved stri ga; anterior stigma round, small, 
its centre and margin dusky ; posterior reniform, clouded with fuscous and black ; behind this is an arcuated
