.2 1 8 • LEPIDOPTERA. 



with black and white ; space between the basal and first lines 

 marbled with dark grey ; that between the first and second 

 lines clouded with blackish-grey, and forming a darker central 

 band with a rather blacker central shade, containing near the 

 dorsal margin a faint orange streak connecting the two lines ; 

 hind marginal region dusted with dark grey, extreme margin 

 dotted wnth black ; cilia very long, dark grey, prettily looped 

 with greyish-white. Hind wings white, clouded with grey 

 to the middle, beyond this broadly dark grey-brown ; cilia of 

 the same colour, but dashed and tipped with white. Female 

 rather stouter, but very similar. 



Underside of the fore wings dark smoky-grey, shading off 

 to white at the dorsal margin ; costa dusted with white and 

 spotted beyond the middle with black ; cilia smoky-grey, 

 with white dashes. Hind wdngs white, dusted with brown 

 toward the costa ; central spot lunate, smoky-black ; some 

 distance beyond it is a slender smoky -black transverse stripe, 

 succeeded by a broad smoky-black marginal stripe dashed 

 with white. Legs pale grey, the tibite barred in front with 

 dark grey ; leg-tufts and abdomen dirty white. 



Not very variable, but the ground colour ranges from a 

 decided grey to nearly white, and in the darker specimens 

 the white borders of the transverse lines are more con- 

 spicuous ; in some individuals, whether light or dark, the 

 orange-yellow markings are extremely faint or even absent. 

 In the collection of Mr. A. J. Hodges is a specimen of a j)ale 

 smoky-gi*ey, the central band darker, but the usually sharp 

 markings all obscured, giving it an unusual appearance. It 

 was reared from a larva found at Wicken, Cambs. 



On the wing at the end of June and beginning of July. 



Larva. — Head rather small, shining, somewhat withdrawn 

 into the second segments, light brown ; body plump, 

 cylindrical, very slightly narrowed at each extremity, bright 

 light chestnut, or pinkish-brown ; dorsal line double, each 

 being slender, black, rather thickened on the hinder portion
