68 LEPIDOPTERA. 



sharply angulated ; hind margin beneath it rather perpendi- 

 cular, to a strong blunt angle or tooth above the middle, 

 immediately beneath which it is deeply concave, but toward 

 the anal angle filled out and smoothly rounded, the whole 

 margin being also minutely crenulated ; dorsal margin also 

 a little rounded, and ciliated with long soft scales; colour 

 pale ochreous, straw-colour, or fulvous-yellow ; very silky in 

 texture ; costal region a little dusted with reddish-brown •,. 

 first line oblique, rather curved, pale purplish-brown ; second 

 line much more oblique and straighter, yet partially curved 

 or sinuous, the extremity which reaches the costa usually 

 thickened or extended outwards in a very small degree, of 

 the same colour; discal spot not indicated; hind margin 

 tinged with fulvous-red ; cilia very short, silky pale yellow 

 or whitish-yellow, interrupted with brown at every nervure. 

 Hind wings broad, hind margin distinctly crenulated and 

 scalloped and having in the middle a larger projecting tooth 

 pv angle ; anal angle rather squared ; pale yellow, tinged 

 with pale fulvous down the middle, and more strongly sO' 

 along the hind margin ; in some specimens there are faint 

 traces of a tawny central spot, and of a faint straight trans- 

 verse line just before it ; cilia white, interrupted with tawny 

 brown at the tips of the crenulations. Female a little stouter ; 

 antennae simple ; otherwise similar. 



Underside of all the wings silky pale yellow, or pale 

 ochreous, finely dusted, the hind margin especially, with 

 fulvous ; the fore wings show faintly the two lines, the 

 second distinctly on the costa. and also have a red-brown 

 discal streak or spot ; on the hind wings is a central red- 

 brown spot, and above it one fainter on the costal margin. 

 Body pale yellow ; legs reddish-yellow. 



Not very variable, but the ground colour fluctuates between 

 very pale yellow, smooth soft ochreous-yellow, and bright 

 light fulvous. In rare instances the thorax — which other- 

 wise agrees with the fore wings — is tinged with canary 

 yellow, and in Mr. Sydney Webb's collection is one such
