276 LEPIDOPTERA. 



slightly hollowed before the anal angle, which is somewhat 

 squared. All the wings glossy, bright fulvous, with the 

 nervures darker brown or blackish, becoming black and dis- 

 tinct on the fore wings as they approach the hind margin ; 

 base shaded with dark brown, and costal and dorsal margins 

 of the fore wings very narrowly edged with the same colour ; 

 hind margin of the fore wings, and all the margins of the hind, 

 bordered with dark brown. The male has, in addition, a long 

 curved black streak arising at the base of the fore wings close 

 to the dorsal margin, crossing the sub-dorsal nervure at one 

 third of its length, and passing obliquely through the middle 

 of the wing, without interruption at the sub-median nervure ; 

 the basal portion of this streak is somewhat obscured by 

 fuscous scales, and its upper side edged with densely crowded 

 fulvous scales throughout its whole length. Cilia of the fore 

 wings yellowish, of the hind yellowish white. 



Under side of the fore wings fulvous with a blackish patch 

 at the base of the dorsal margin, and shaded with the same 

 along that margin to the anal angle ; apex and hind margin 

 greyish yellow ; of hind wings dull greyish yellow or 

 yellowish fulvous, thickly dusted with grey, but with a broad 

 stripe of yellow fulvous from near the base to the anal angle ; 

 cilia of all the wings yellowish with the base grey except 

 that towards the anal angle of the hind wings they frequently 

 become whitish. 



Antennas blackish brown above, with fulvous bars, yellowish 

 beneath, the tip of the club fulvous. 



Very little subject to variation, but Mr. G. T. Porritt says 

 that a bone-coloured variety is occasionally taken near Wake- 

 field, Yorks. Mr. C. A. Briggs has one, from Folkestone, of 

 a very pale yellowish, almost silvery white, and Mr. S. Stevens 

 another ; and one of a pale greyish ochreous. On the other 

 hand, a female specimen in Dr. Mason's collection is singu- 

 larly dark, and of rather large size, the marginal border black- 

 brown, broadly shaded inwards and extending along the 

 nervures of the fore wings, while the hind are almost entirely
