120 LEPIDOPTERA. 



darker grey ; cilia yellow-grey clotted with black. Hind wings 

 not broad, the costal margin remarkably straight and the 

 apex angulated ; hind margin rather sinuous or curved, most 

 prominent in the middle ; semitransparent, pale grey, faintly 

 dusted with pale yellow ; before the middle is a slender 

 smoky-black stripe, followed by another more curved and 

 sinuous, and by a third, more diffused, along the hind 

 margin ; cilia yellow-grey, spotted with black. Antenna? of 

 the female simple ; body much thicker ; fore wings rather 

 longer and more ovate, semitransparent between theuervures, 

 which are thickened and more extensively blackened ; the 

 general colour grey, often with very little yellow dusting ; 

 hind wings also larger, greyer, and much more thinly 

 clothed with scales. 



Underside of all the wings smoky brownish-grey, minutely 

 dusted with yellow and with black ; the transverse lines 

 obscurely indicated ; cilia more distinctly spotted with black. 

 Body reddish-brown ; legs excessively tufted with similarly 

 coloured long hair- scales ; tarsi barred with black. 



Usually a sufficiently constant species in both colour and 

 markings, yet specimens showing slight variations in the 

 ground colour toward grey-brown, or to an excess of black 

 dusting, or toward yellowish-white in the paler stripes, and 

 also in the depth and distinctness of the black transverse 

 stripes, maybe secured without very much difficulty; and 

 there is, I think, in London a tendency towards yellow dusting 

 in the male, and to blacker general colour in the female. In 

 the collection of the late Mr. H. Doubleday at Bethnal Green 

 Museum is a specimen wholly black ; on the other hand, 

 Mr. S. J. Capper has examples of the same sex from the New 

 Forest of a pale reddish-grey with the transverse lines light 

 brown ; and in the late Mr. F. Bond's cabinet are males from 

 Scotland of a very curious pale grey. In his collection, now 

 in Mr. Webb's possession, is also a most singular gynandrous 

 specimen ; its body and wings being female, but its antennre 

 partly male. This was taken in the Begent's Park, London.
