Head and thorax hoary gray ; antennae ciliated in the male ; pale cinereous : an- 

 terior wings pale hoary or whitish gray, the costa slightly clouded with fus- 

 cous ; with a cloud of the same hue at the base of the wings, divided from the 

 teUform stigma by a very obscure transverse waved striga ; anterior stigma 

 round, small, its centre and margin dusky ; posterior reniform, clouded with 

 fuscous and black ; behind this is an arcuated subraoniliform striga, beyond 

 which the rest of the wing is deep fuscous, with an undulated white striga, 

 composed of approximating wedge-shaped spots ; in the margin itself is a 

 series of minute black subtriangular dots : cilia pale ash : posterior wings pure 

 white : abdomen of a glossy silken ash colour. Female nearly of an uniform 

 pale cinereous, with the stigmata and costal spots nearly obsolete. 



The spots on the abdomen of the male, as represented in the plate, appear to 

 arise from accident, seemingly from some of the hirsuties being abraded. 



I have seen two specimens only (the sexes) of this very con- 

 spicuous and apparently novel species ; they were captured in 

 July, 182T, near Barnstaple, Devonshire, by Mr. Raddon, through 

 whose kindness I am enabled to introduce the accompanying figures 

 and descriptions. 



Sp. 27. cinerea. AUs anticis cinereis, fuliginoso nebulosis, strigis duabus 

 denticulatis atris. (Exp. alar. $ 1 unc. 6—8 lin. : $ 1 unc. 4 Un.)

Thorax cinereous, anteriorly dark : head cinereous ; antennae griseous : anterior 

 wings griseous-ash, with dusky shades ; with two black dots at the base, a 

 slender denticulated striga before the middle, and another behind ; the anterior 

 stigma is nearly obsolete, but the posterior is distinct; between them is a 

 transverse angulated fuscous or rufescent striga, arising from a dusky spot on 

 the costa, and passing to the inner margin ; the hinder has an obscure waved 

 striga, and a series of minute black dots on the margin itself: cilia griseous- 

 brown ; posterior wings whitish, with a dusky central spot, and a series of 

 blackish dots on the margin. Female considerably darker, and destitute of 

 the griseous hue, the strigae more evident but less denticulated ; the posterior 

 wings cinereous. 



This species diflPers considerably in habit from the rest of the genus, in the ob- 

 scurity of the stigmata particularly, and in the total absence of the teUform 

 one. 



Caterpillar sUghtly hairy, greenish-brown, with three reddish stripes on the back, 

 and a glossy-brown head ; the legs yellowish-white. 



Not common, taken occasionally on a heathy common to the
