Genus Heliria Stal. 



The members of this genus are characterized by having a dis- 

 tinctly step-shaped dorsal crest. 



Two members of the genus are known to occur in Kansas. These 

 Van Duzee separates by the following key : 



KEY TO SPECIES. 



A. Larger, 12-13 mm.; grey or brownish grey; posterior foliole of the crest 

 Httle elevated above the dorsal line anteriorly, its hind angle subacute; 

 humeral angles greatly produced. cristata. 



AA. Smaller, 8 mm., darker brown; posterior foliole of the crest, when well 

 differentiated, elevated at least its own width above the dorsal line.
