Dyar suggested the synonymy of Columbia and crenana in 1904. 

 An examination of the genitalia verifies his contention. The forms 

 albidorsana and mediostriana are merely color varieties and there- 

 fore should be treated as synonyms. There is nothing to be gained 

 to holding such names where they apply only to color varieties of a 

 variable species.
