416 Hymenoptera in America North of Mexico 



I have seen one undescribed Nearctic species in the U. S. Natl. Museum collection, but sup- 

 pose that there are other undescribed Nearctic species because Townes (1970) said that Ethelur- 

 gus is a moderate sized genus. Males of Ethelurgus will not key to the subtribe Ethelurgina in 

 Townes (1970) because only the females have the apical margin of the clypeus impressed.
