oblique Init very little curved ; dorsal margin nearly straiglit ; 

 colour very pale olive-brown, or brownish-white; basal line a 

 narrow, oblique, hardly curved, grey-brown stripe enclosing 

 several faint rippled grey-brown lines ; first and second lines 

 near together and near to the middle of the wing, both 

 curved and black-brown, the second more oblique, each most 

 distinctly indicated by black-In'own dots on the nervures, 

 yet enclosing a paler grey-brown central band ; liefore this 

 band, and also beyond it, is a stripe of the ground colour regu- 

 larly dotted with blaclc. each dot placed in a whitish oval ; 

 beyond the second of these is another row of similar dots 

 followed by a broad grey-brown stripe, through which runs 

 the scalloped white subterniinal line ; extreme hind margin 

 edged with pairs of black dots ; cilia greyish-white. Hind 

 wings long and narrow, rounded behind ; silky greyish- 

 white, tinged behind with dusky-brown, through which runs 

 a very faint whiter liand ; hind margin dotted with black ; 

 cilia silky greyish-white. Female decidedly smaller ; with 

 simple antenna3. body much stonter but short ; fore wings 

 trigonate and sharply pointed, narrower, and usually ])aler 

 in colour. 



Underside of the fore wings pale smoky-brown, more 

 yellow-brown toward the costa ; second line cloudy-black, 

 followed by an ol)SCure smoky-brown band. Hind wings 

 smoky whitish-brown; central spot visible as a black dot; 

 beyond it is a distinct and very sinuous black-brown trans- 

 verse stripe; and further back another, broader, shading off 

 to the hind margin, where is a row of brown dots. Body 

 and legs dull grey-brown. 



Usually not very variable, but in the north of iScotland 

 there is a tendency to unicolorous dull grey, or to a suffused 

 clouding of grey-black from the bands, while in the east of 

 that country it is occasionally nearl}- black. In the collec- 

 tion of the late 3Ir. H. Doubleday, now in Bethnal Green 

 Museum, are several specimens of almost unicolorous dark- 

 grey or black-grey ; Dr. JIasoii possesses a female of a lead-
