CRASPEDIA. 225 



broad, white or yellow, with two transverse lines, and a central 

 spot. The hind-wings are rounded or angulated. The moths 

 are generally called " Waves " by collectors. 



The larvae are slender and cylindrical, feeding concealed on 

 low plants, and the pupae are brown, and enclosed in fine 

 cocoons. 



As the generic name Acidalia (Treitschke) is preoccupied, I 

 adopt the name used by Mr. Moore for this family.

 Western Asia, and Northern Africa. It expands about an inch.
