The genera Scolia and Elis of Fabricius, and Liacos of Guerin, 

 have been split up into the following sub-genera by de Saussure and 

 Sichel in their "Catalogue Specierum Generis Scolia." 



(a) Triscolia-r— Anterior wings with three cubital cells and one 



recurrent nervure. 



(b) Dlscolia — Anterior wings with two cubital cells and one re- 



current nervure. 



(c) Trielis — Anterior wings with three cubital cells and two re- 



current nervures. 



(d) Dielis — Anterior wings with two cubital cells and two re- 



current nervures. 



{e) Triliacos — Anterior wings with three cubital cells, the third 

 discoidal cell petiolated. 



(f) Di liacos — Anterior wings with two cubital cells, the third 

 discoidal cell petiolated. 



In this family many of the species belonging really to different 

 sub- genera bear so close a resemblance one to the other that a careful 

 examination of their anterior wings is absolutely necessary for their 

 discrimination.
