with black ; stigmata detacbed — the orbicular a rough black 

 triangular spot, claviform a somewhat rounded black spot, 

 reniforni a round vhitr spot with a black ring which throws 

 off spurs at the base ; second line much broken, formed of 

 black dusting ; beyond it are clouds of similar black atoms 

 near the apex, the hind margin, and the anal angle ; these 

 three clouds, and also the first and second lines, are prettily 

 edged by fine white lines ; hind margin regularly dotted 

 with black ; cilia shining silvery white. Hind wings not 

 very broad, the hind margin sinuous and a little curved ; silky, 

 smoky white, darker along the hind margin ; cilia whiter. 

 Female with similar markings often greyer or darker. 



Undersides of all the wings glossy pale smoky grey, except 

 that a yellowish shade lies along the costa of the fore wings. 

 * Body and legs dusky white. 



Not very variable, but in some districts all the specimens 

 have the grey tint, while in others a more olive or even faint 

 greenish shade is noticeable ; occasionally also a specimen is 

 found in which the ground colour is obscured and shaded 

 with smoky black. There is also some variation in size, 

 occasional specimens being very small. 



On the wing at the end of May and in June, and as a 

 second generation at the end of July and in August. 



Lakva half an inch long; the head very nearly of the 

 width of the second segment, the lobes rounded ; highly 

 polished, intensely black; dorsal and anal plates similar; 

 body cylindrical and of nearly uniform width, tapering only 

 a very little at the extremities ; segmental divisions well 

 defined ; ground colour dingy ochreous-brown or sometimes 

 purplish-brown ; a tine brown line, widening at the seg- 

 mental divisions, extends through the middle of the dorsal 

 area, also a wavy brown stripe along the subdorsal, and 

 another one along the spiracular region ; all these lines 

 together giving a reticulated appearance to the paler ground 

 colour; raised dots very dark brown, and shining; spiracles
