with golden-brown, or yellow-grey or rosy-grey marbled with 

 dark brown ; basal line faintly indicated by two small blackish 

 carves ; first line curiously placed, its dorsal extremit}^ not 

 far from the base and leaning outwards, incomplete but 

 double, golden brown enclosing a whitish line ; second line 

 obscure but duplicated, straight, reddish-brown, enclosing a 

 faint white thread ; subterminal line a series of black angles, 

 some of them almost right angles, partially edged outside 

 with white, and those above the middle having on their inner 

 side long black wedge-shaped streaks ; orbicular stigma 

 altered into an elongated loop with a whitish edging ; 

 touching it, but below the median nervure, is an oblique 

 thick silvery-white Y-shaped spot occasionally divided into 

 two, the upper U-shaped, the lower round and nearly touching 

 the second line ; at the extreme hind margin are two very 

 slender parallel white lines ; cilia rich brown, dusted with 

 whiter. Hind wings rather long and ample ; dull brown, 

 paler at the base, but with brown nervures ; cilia white. 

 The female has broader fore wings, which are less suffused 

 with golden brown, the markings more sharply denned, and 

 the silvery spot or spots a little broader ; the tawny colour is 

 obscure on the lateral tufts but extends to the underside of 

 the anal tuft. 



Underside of the fore wings pale drab, obscurely clouded 

 with pale brown ; nervures darker. Hind wings dusky white, 

 abundantly dusted with brown, less so toward the base. 

 Body and legs grey-brown, the tibise of the latter black-brown 

 barred with dull yellow. 



Apparently not variable beyond the degree already men- 

 tioned, except that there is some reason to believe that the 

 second generation is darker than the first. 



On the wing in May, and as a second generation in August 

 and September. 



Larva like the rest, having only twelve legs ; head small 

 and rather flattened ; body tapering and becoming largest at
