The Sword-grass Moth. 



The Sword-grass Moth is common throughout the greater 

 part of Europe, Northern Africa, and Siberia. It expands 

 about two inches and a quarter. The head is pale grey, and 

 the thorax black, with scattered white hairs. The tegular are 

 white. The abdomen is covered with long grey hair above, 

 with a black shade in the middle, and yellowish-grey hair on 

 the sides, forming zig-zag tufts. 



The fore-wings vary from dark brown to grey. On the 

 hind margin is a dark line containing four or five white dots 

 near the apex of the wings. From the base to the hind 

 margins, the whole of the wings are covered with numerous 

 fine longitudinal brown streaks on an ashy-grey ground. 

 The outer part of the wings is dark brown, especially in the 

 neighbourhood of the reniform stigma. There are no trans- 

 verse lines. The orbicular stigma is elongated, and similar in 

 shape to the reniform, but smaller. Both are surrounded by 

 slender dark lines, and the reniform stigma is shaded externally
