wings with, grey, but especially so beyond the second line, is 

 now establishing itself in the London suburbs. Mr. R. 

 Adkin has reared this form in some numbers from his 

 garden at Lewisham — all devoid of the band. A still further 

 development in this direction has just been brought under 

 my notice — Mr. W. il. Christy has reared from the eggs of 

 a female moth taken in the New Forest, specimens very 

 darkly dusted with grey-black, and one in which the wings 

 are wholly smooth shining smoky-black, except that the 

 nervures are blacker, but the cilia of the normal pale colour : 

 In another variety of the unhanded form, found more 

 especially in the Eastern counties, the ground colour is 

 wholly pale brownish ochreous, or faintly I'eddish. 



On the wing in June and July, and as a partial second 

 generation, in August and the beginning of September. 



Larva moderately stout, transversely wrinkled, tapering in 

 front ; undersurface flattened ; sides projecting and puckered ; 

 head small and rounded, reddish-brown thickly dusted with 

 black ; body dull brown, the hinder four segments paler and 

 having an ochreous tinge ; a grey or dark brown dorsal shade 

 appears on the second to fourth, and the tenth to thirteenth 

 segments ; the intermediate segments having brown V-shaped 

 markings pointing backwards, the apex of each mark being 

 produced into a blotch on the succeeding segments ; an 

 indistinct whitish threadlike dorsal line, and a conspicuous 

 similar dorsal spot, appear upon the ninth segment ; spiracular 

 line waved, spreading out on each segment, whitish-ochi'eous; 

 undersurface dark purple, marbled with brown, darker than 

 the ground colour, and with numerous dee|i transverse 

 wrinkles, and longitudinal dark grey lines ; a blunt pale 

 wedge-shaped blotch on each segment contains two brown 

 lines, and is followed by a smaller one in which is a grey V, 

 the apices of these markings point forwards ; anal segment 

 paler beneath. (C. Fenn.)
