apex .inoculated ; hind margin gently rounded ; dorsal margin 

 also a little filled out and curved ; colour pale grey : basal 

 line obscurely black, most distinct on the nervures ; first line 

 also black, erect, thrown out in two sharp angles, that in the 

 middle of the wing giving off a long black streak, the other 

 a shorter one, but both streaks crossing the central band ; 

 second line distinctly black, angulated sharply outward 

 beneath the costa, thence formed into long loops between the 

 nervures, each of which is blackened ; central band of rather 

 a browner shade of grey, much cut up by the black nervures 

 and streaks ; also blackened on the dorsal margin ; discal 

 spot a black dot ; second line edged on its outer side, 

 throughout its loo])S and angles by a slender white line ; 

 from its jiriucipal angle a black streak, clouded, and broken 

 in the middle, runs obliquely to the apex of the wing ; sub- 

 terminal line hardly perceptibh- whiter ; extreme hind 

 margin edged with black streaks; cilia pale grey. Hind 

 wings rather long, rounded behind, silky greyish-white, more 

 smoky toward the base and hind margin, and having a 

 hardly perceptible curved grey central transverse line ; hind 

 margin dotted with black-brown ; cilia whitish-grey. Female 

 similar. 



Undersides of all the wings very silky whitish-grey ; fore 

 wings with the discal spot visible, and the second line much 

 blackened from the costa ; jialer below ; hind wings with a 

 distinct black central dot, and a bent transverse grey line in 

 the middle. Body and legs grey-brown. 



Subject to local variation in both colour and size. Those 

 taken on the coast of Kent are rather tinged with brown, and 

 the black streak which runs into the apex of their fore 

 wings is continued unbroken from the Jird line. Scottish 

 specimens are usually quite small, and many of them, those 

 from the Orkneys especially, have the central band very 

 prettily filled up with brown-grey, rich brown or black- 

 brown ; the basal blotch being of the same colour. Some 

 of those from the Shetland Isles have, along with these
