102 LLOYDS NATURAL HISTORY. 



parent spots, which are sometimes so much extended as to 

 cover the greater part of the wing, except the borders. The 

 costal nervure is wanting on the hind-wings, and there is 

 only one sub-median nervure on the fore-wings, and one or 

 two on the hind-wings. The Moths are gregarious, and have 

 a rapid flight, wheeling round and over bushes in the daytime, 

 though they will also settle on flowers. The larva is furnished 

 with tubercles bearing tufts of hair, and the pupa is enclosed 

 in a slight cocoon. 



Zygcena, Fabricius, the typical genus of this Sub-family, is 

 extremely numerous in species in Asia and Africa. One species 

 only is found in Europe.

It is hardly necessary to say much more respecting the 

 genus than we have already said respecting the Family. There 

 is one sub-median nervure on the hind-wings. The European 

 species is sufficiently characteristic of the whole genus.
