118 BRITISH MOTHS 
blackish mark occupying the place of the supplemental stigma; the anterior stigma is sometimes obsolete. 
Behind the posterior stigma is a double row of blackish dots, and there is a row of small whitish dots along the 
apical margin of the wing ; the hind wings are often whitish, slightly shaded with brown, with a row of marginal 
dots ; they are variable in colour, however, in different specimens. 
Mr. Bentley has described a series of varieties of this species in the “ Entomologist,” proving Mr. Stephens’ 
supposition, that A. radia and radiola were varieties of but one species, to have been correct. 
Taken in June in numerous places round London, as well as in various distant parts of the country. 
SPECIES 9.—AGROTIS CINEREA. Purare XXITTI., Fre. 8, 9. 
Synonymes.— Noctua cinerea, Hiibner ; Treitschke ; Curtis Brit. 
Ent., pl. 165. 
Bombyx denticulatus, Haworth. 
Female.—Noctua obscura, Hiibner. 
This very well marked species measures from 1+ to 12 inch in the expansion of the fore wings, which are of an 
ashy colour, shaded slightly with dusky, with a short angulated slender brown fascia near the base, and another 
still more irregularly angulated before the middle of the wing, with the anterior stigma and the supplemental 
teliform one obliterated; a little beyond the middle of the wing runs a waved brown bar, followed by the 
posterior stigma, which is very small, dark-coloured, and ear-shaped, and succeeded by a slender, much-waved, 
dark streak, then a series of obscure patches, and a row of black dots on the apical margin itself ; the hind wings 
buff white, with a dusky central lunule, and a series of marginal dots ; the thorax grey, with a dark bar in front. 
The antennz are pectinated in the males. The female is considerably darker in colour, with the streaks darker 
but less waved, and the hind wings ashy. The want of the two anterior stigmata, as well as the structure of the 
caterpillar (which is slightly hairy, and of a greenish brown colour, with reddish dorsal stripes) separate this 
species from the rest of the genus. It appears to be very widely distributed, although a rare species. We have 
been favoured with the sight of a beautiful variety taken near Carlisle by T. Reeves, jun., Esq. 

SPECIES 10.—AGROTIS ALPINA. Puare XXITI., Fie. 18. 
This new and distinct species measures 13 inch in the expanse of the fore wings, which, as well as the body and 
hind wings, are of a pale buff-coloured grey, the costa of the former marked before and behind the middle as well 
as near the tip with a dusky spot; there is also a patch of this colour near the base towards the posterior margin, 
and another more elongated extending to the anterior stigma which is round and grey-coloured, open in front, 
and running to the costa ; this is succeeded by asmall dark patch, and this by the second stigma, which is r 
broad and ear-shaped, dusky within, and edged, as well as the other, with 
ather 
brown: from the outer edge of the 
second stigma extend three dusky rays, separated by the whitish spaces occupied by the veins of the wing ; these 
rays are cut in the middle by a very much curved series of dusky slender arches, which is followed by 
a row of triangular dark-coloured patches parallel to the apical margin, which is further marked with 
minute dusky arched dots; the abdomen and hind wings are of a uniform silky, buffish 
grey, with the cilia 
nearly white. 
Taken on Cairn Gowr in Perthshire, at an elevation of three thousand feet, by J. W. Douglas, Esq. ; to whom 
we have to present our thanks for an opportunity of describing and figuring this fine addition to the genus. 
The unique specimen captured was a female, so that it is from analogy with some of the preceding species, 
especially A. suffusa, that I introduce it at the end of the present section of the genus. 
Section IT.—Antennz of the males not pectinated, producing only fascicles of hairs.
