Characters of the family. 



The European writers on whose work the former usage of this 

 genus was based, accepted the restriction to pentadactylus by Poda. 

 This is not in accordance with the International Rules. The earliest 

 actual designation of a type which is validated by these rules, is that 

 of Curtis. We accept this fixation. 



Only one species has been taken in North America.

 tween this and the median band there is a heavy costal spot which does not 

 reach the inner margin of the first lolie. All of these marks are margined with
