Xumerically this genus is the largest of the LibeUuUnse, com- 
prising about 45 species. The imagos frequent the swampy shores 
of lakes and rivers, but seem to like moist woods and open prairies 
just as well, flying in great swarms wherever they occur. They 
are readily distinguished even in flight, from the yellow or red- 
dish yellow tone of their colors. The following table includes the 
species of the Transition and Upper Austral life areas.
