84 LEPIDOPTERA. 



spots on the costa, from the outer two of which arise black, 

 indented, irregular,, slender, transverse lines, both of which 

 lose themselves in the broad dorsal portion of the transverse 

 band ; a third such line arises from the subapical blotch and 

 zigzags to the anal angle. At the apex of the discal cell is a 

 black spot, and on the hind margin a regular row of round 

 black dots ; cilia white. Hind wings short and rather 

 narrow, semi-transparent ; whitish, with faintly brownish 

 nervures ; a cloudy lunate spot at the end of the cell, and 

 beyond it a faint greyish cloudy transverse band ; hind 

 margin rather sinuous, regularly spotted with black, the spots 

 becoming cloudy and confluent near the anal angle ; cilia 

 white. 



Female with the antennae very shortly pectinated, the teeth 

 often deflected, or prostrate, along the shaft, and indistinct, 

 body stouter ; hind wings rather more smoky- white ; the 

 black spot at end of the discal cell much smaller, sometimes 

 a mere dot ; otherwise similar. 



Underside white ; fore wings extensively banded and 

 blotched with pale smoky-purplish, especially under the dark 

 markings of the upper side ; hind margins of all the wings 

 strongly and sharply spotted with black ; body covered with 

 very soft downy white scales ; legs purplish-black in front, 

 but heavily tufted with white scales. 



Usually not variable, but a specimen in the cabinet of Mr. 

 Sydney Webb has the central band narrowed, deeply in- 

 dented, and nearly divided in the middle ; and one in Mr. 

 Arthur Robinson's collection is a most exquisite specimen, 

 having no indication of either central dark band or of 

 the subapical blotch except that their margins exist as 

 slender lines. Both were obtained in Tilgate Forest. 



May, and to the middle of June. 



Larva rather stout ; head flattened in front and partially 

 withdrawn into the squared flat front of the second segment, 

 which is large and conspicuous ; fourth segment rather
