These are rather small and very hairy moths, with a tuft at 

 the end of the abdomen. The antennce are bi-pectinated, and 

 the middle and hind tibiae are armed with two small apical 

 spurs. The larvae are gregarious, and their hairs and the dust 

 from their nests are more strongly urticating than those of any 

 other European genus. 



This genus is sometimes referred to the NotodontidcB.

This moth is found throughout nearly the whole of Europe, 

 but, though common on the Continent, and often very destruc- 

 tive to the trees, it is not a British specieg.
