 per cent occurs (Ries, Journ. Agr. Research, 1926, 32:284). Introduced. 



"^ If the Erlangen List is accepted, this family name will have to be changed to Astatidae, and 

 the genus Cephus Latreille will fall as a synonym of the genus Astatus Jurine (Panzer). 

 "2 This name will be supplanted by Astatus, if the Erlangen List is Accepted.
