distinct throughout, also very little waved or indented, edged 

 on the outside with a dusky white line which shades off into 

 a broad whitish-brown oblique band, beyond which is a faint 

 whiter subterminal line ; reniforrn stigma indicated by a 

 clouded deep black spot; extreme hind margin edged with 

 black streaks or crescents ; in the middle area of the costal 

 margin are two pale oblique streaks edged behind with black ; 

 cilia purplish-umbreous dotted with paler brown. Hind 

 wings rather long, with a sinuous hind margin ; smoky-white, 

 the nervures rather darker ; cilia smoky-white. Female very 

 similar. 



Underside of the fore wings pale smoky-brown ; outer 

 half of the costal margin and the hind margin dotted with 

 white ; the second line faintly visible, and the space beyond 

 it a little paler. Hind wings smoky-white with smoky- 

 brown nervures ; central spot a streak of the latter colour ; 

 beyond it is a faint, similar, transverse shade. Body whitish- 

 brown ; legs well furnished with spines ; colour pale 

 brown. 



On the wing from the end of June till August, and 

 apparently as a partial second generation, in September. 



Larva scarcely known. It is figured in the young state 

 in the Tidschrift voor Entomologie, vol. 23, plate 7, and 

 also described, under the name of tccnialis. Professor von 

 Leewen obtained eggs, and kept the young larvae alive till 

 the end of September, when they commenced to hybernate, 

 but died before the spring. These young larvas he described 

 " slender, but much thickened from the fifth to the ninth 

 segments ; head and next three segments quite small, and 

 the fifth very suddenly thicker ; the reduction in size from 

 the ninth to the tenth is equally sudden, and the hinder 

 segments continue small ; anal prolegs rather extended, and 

 there is a pair of abdominal prolegs on the eleventh segment ; 

 the true legs on the other hand being strongly developed " ; 

 thus it is at this stage distinctly a looper, and one of the
