lilackisli mark occupying the place of tlie 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, iiowever, in different specimens. 



Mr. Bentley lias 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.

This very well marked species measures from l^- to If 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 j 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 antennw 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 tlie 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. Plate XXIII., Fig. 1.3. 



This new and distinct species measures 1 A 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 whicli is round and grey-coloured, open in front, 

 .md running to the costa ; tliis is succeeded by a small dark patcli, and this by the second stigma, which is rather 

 broad and ear-shaped, dusky witliin, and edged, as well as the otlier, with 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, whicli 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, huffish 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 II. — Antenna? of the males not pectinated, producing only fascicles of hairs.
