I follow Saussure and Sichel in their definition of this genus ; but Kirby, Trans. 

 Ent. Soc. Lond. 1889, p. 443, separates it into two, using the name Scolia for the 

 section with three cubital cellules, and Discolia for that with two only. 



The species are not nearly so numerous in the western as in the eastern hemisphere. 

 As regards the arrangement of the species in this genus, as also in Elis, I have followed 

 Saussure and Sichel in their well-known monograph, * Catalogus Specierum Generis 

 Scolia' (1864).
