This species was re-named by Bruner when he found it necessary to 

 restore Harris's O. gracile, which on the authority of Scudder had been 

 considered a synonym o{ Xiphidium fasciatuffi, De Geer. 



It is very limited in distribution, being known only from Nebraska, 

 where, however, Bruner says it is '" quite common in the vicinity of West 

 Point, about the margins of ponds, etc." He also took it at the electric 

 liglit in Eincoln.
