354 LEPIDOPTERA. 



a very slender, indented and irregular whitish thread, out- 

 side which is a smoky-brown cloud ; and inside it sometimes 

 indications of a few blackish wedges ; orbicular and reniform 

 stigmata rather small but conspicuous, ashy-white, the latter 

 centred with yellowish ; the rest of the discal cell, before and 

 between them, deep black; claviform stigma black, broadly 

 wedge-shaped ; cilia greyish-brown. Hind wings whitish ; 

 nervures and hind margin dusted with golden-brown ; cilia 

 white. Female similar, rather stouter; hind wings in some 

 specimens more suffused with grey-brown. 



Underside of fore wings shining smoky-grey, with the 

 nervures paler ; of the hind wings whitish, with the costal 

 margin very broadly dusted with brown ; hind marginal line 

 brown. Body golden-brown ; legs purple-brown, barred with 

 pale brown ; leg tufts smoky purplish-grey. 



Very little variable, and this mainly in the shade of colour 

 of the fore wings, which in some specimens is of a jjaler 

 purple-brown, in others, but more rarely, pale slate-brown ; 

 in some examjDles the first transverse line is complete, 

 dividing the pale subcostal stripe ; and I jDoasess a specimen 

 in which this line is very distinctly shown and more perpen- 

 dicularly placed than usual. In the collection of Mr. F. J. 

 Haubury is another even more strongly marked. Specimens 

 from the Isle of Wight seem to have a general tendency 

 toward greyer colour, those from western districts to more 

 purple shades. 



On the wing in August and the beginning of September. 



Lakva moderately stout, especially behind the middle, but 

 with head and anal segment rather small ; pale slate grey ; 

 dorsal line of the ground colour, bordered on each side by a 

 purplish-brown stripe, which is sometimes broad and distinct, 

 at others divided into two separate lines which represent its 

 margins, having on its upper edge, on each segment from the 

 third or fourth, a distinct black spot ; beneath are two more 

 longitudinal stripes faintly purplinh-brown or grey-brown, the
