194 LEPIDOPTERA. 



with three conspicuous tufts of raised brown and white scales 

 along the discal cell; first line curved, slender, very pale 

 brown ; second line slightly sinuous but nearly parallel with 

 the hind margin ; space between these lines light brown, 

 forming a broad central band, darkest towards the second line, 

 but dotted with white along the costa; outside the second lino 

 is a faint transverse series of brownish clouds, and a light 

 brown stripe, dashed with darker on the nervures, lies along 

 the hind margin ; cilia long, whitish, faintly intersected with 

 brown. Hind wings ample, rounded, whitish-grey, shaded 

 with extremely pale brown, rather darker towards the hind 

 margin; cilia similar. Sexes alike. Underside of the fore 

 wings dull grey-brown with whitish spots on the costa ; of 

 hind wings white, the costal half profusely dusted with brown, 

 and with a brown central lunule; body and legs white. 

 Variable in the degree of light brown shading in the central 

 band and hind marginal space ; and in the general colour of 

 the markings, which tend in some degree to disappear. In 

 Mr. W. H. B. Fletcher's collection is a specimen of a pure 

 white except a very slender brownish transverse stripe, and I 

 have one wholly white. 



On the wing from the end of June to the end of July, and 

 sometimes till the middle of August. 



Larva of even thickness, but \vith the head small, shining, 

 pinkish, sometimes with brown markings; body pinkish- 

 orange, pale pink, or even ivory-white ; tubercular spots 

 yellow, distinctly raised, and bearing tufts of hairs, of which 

 those in the centre are much longer than the rest, and those 

 on each side of the anal segment of double length ; rather 

 long tufts are also on each side of the head. Dorsal line 

 double, light grey; subdorsal line indicated by oblong or 

 angular black markings on the middle segment, and on the 

 seventh and eleventh increased in size, so as in some cases to 

 meet across the back; legs brown; prolegs pinkish or 

 yellowish, tipped with brown ; the shorter hairs white, the 

 longer dark brown.
