Subfamily I. LYG^JNtE. 



In this subfamily the abdominal segments are nearly equally 

 long, all the stigmata are situate on the connexivum, and the 

 hemelytra are either not or very slightly punctured. 



The Lygseinse are very widely distributed and comprise the 

 most highly coloured representatives to be found in the whole 

 family Lyggeida^.

 'ifem. iv, p. 98 (1874). 



Hemelytra either totally or to a very considerable extent 

 fuscous or infuscated ; apical margin of corium straight. 



The Lyf/cearia contain a number of genera which are both 

 necessary and valid, but constructed on characters which are 

 unavoidably of a somewhat superficial character. Most of these 

 genera were founded by Stal, who was the first to really study 

 the group, and although colour differences have been often used
