antennae short and slender, but decidedly pectinated with 

 short stout teeth ; pale- brown or grey-brown ; thorax broad 

 and stout ; abdomen very large and heavy ; both red-brown 

 or pale, or dark, grey-brown, very dull in colour; fore wings 

 coarsely scaled, larger and much longer than in the male, 

 with the margins more curved, and the hind margin much 

 more oblique ; reddish-brown, or grey-brown, sometimes much 

 shaded with ashy-grey or dark grey-brown, hardly two 

 specimens being quite alike ; transverse lines as in the male 

 but rather more oblique, and in many cases having, on the 

 sides nearer the base of the wing, a broad shade of whitish ; 

 but these whitish shades vary greatly in degree, and the lines 

 themselves in their distance apart and consequently in their 

 positions on the wings ; the faint edging of the shade beyond 

 the second line is just visible. Hind wings long, rather 

 thinly scaled, dull brown, nervures decidedly darker ; cilia 

 whitish. 



Underside of all the wings, in the male, red-brown or orange - 

 brown ; the cilia of the hind wings tinged with yellowish ; 

 of the female dull brown or grey-brown, with a faintly 

 indented transverse pale line in the fore wings ; body and 

 legs of the colour of the wings, the latter with dense tufts 

 of paler scales. 



Besides the variation in pale shading in the male, and in 

 grey or brown colouring and paler clouding in the female, the 

 two transverse lines, as already remarked, are most unstable 

 in position ; in the case of some females placed so far apart 

 as to enclose between them nearly one-third of the length of 

 the wing ; in others, and especially in some of the males, 

 parallel and almost close together. In rare instances they 

 actually coalesce ; one such is in Mr. Sydney Webb's collec- 

 tion, another in that of the late Mr. H. Doubleday, in Bethnal 

 Green Museum. In a female specimen in my own collection, 

 obtained at Belfast, both lines are absent from the right fore 

 wing, which has merely a whitish oblique cloud. Another 

 has the first line bordered outwardly with black-brown. Dr.
