224 LEPIDOPTERA, 



black crescents, sharply cut off accl concave outwardly; 

 outside this the hind marginal region is softly tinged with 

 yellow-brown or pale tawny ripples, and the sharp crenula- 

 tions are slenderly edged with the same ; cilia pale brown. 

 Female rather larger and stouter; antennae simple; wings 

 broader, with the ground colour and markings all brighter 

 and lighter in colour, otherwise similar. 



Underside of the fore wings yellow-brown, clouded with 

 smoky purplish-brown to beyond the middle, where is a broad 

 black-brown transverse band throwing off similar clouds to 

 the margin below the apex ; discal spot black. Hind wings 

 yellow-brown dusted or stippled with minute purplish-brown 

 lines ; central spot black ; beyond it is reproduced the slender 

 rippled line of the upper side in crescents with dotted points. 

 Body and legs pale brown. 



Casual specimens of a second generation are nearly always 

 smaller in both sexes, of a more dull colour, and the umbreous 

 markings more suffused with smoky-black. A specimen of 

 the ordinary brood, taken in Camberwell some years ago by 

 my eldest son, is also rather small, and its wings narrower 

 than usual, while the transverse lines and dark blotches are 

 rendered distinct and much intensified in colour, and the 

 hollowed stripe of the hind wings is bordered with brownish- 

 wliiU. In the cabinet of the late Mr. F. Bond, in Mr. Webb's 

 possesion, are two specimens, male and female, entirely suf- 

 fused with deep dark umber-colour, and almost devoid of mark- 

 ings. For some years past specimens tending very strongly 

 in this direction — uniformly clouded with dark umbreous — 

 have been taken very locally in East London ; and from one 

 or more female specimens of the same colour found in North 

 London eggs have been obtained and considerable numbers 

 of this form reared. An example taken by Mr. C. A. Watts 

 in Regent's Park, London, is exactly intermediate, having the 

 dark brown colour, but the markings visible in blacker tints ; 

 its thorax and the base of the wings, however, are pale drab ; 

 and this peculiarity is usually present in the darkest forms.
