LEPIDOPTERA HETEROCERA. 399 



Europe. 



The European species will form three groups. In the first 

 group, which is the type of the genus, the antennae have fascicu- 

 lated cilia?, the abdomen has a pale basal band, the wings are 

 ample and have distinct rounded teeth and no discal mark. In the 

 second group the antennae are pubescent; the hind tibiae are in- 

 crassated, and the wings are nearly entire. In the third group the 

 size is small, the antennae have short and frizzled ciliae, and 

 the wings are nearly entire.
