"* The species of this genus are not satisfactorily defined, and, until a revision has been 

 prepared, they cannot be satisfactorily determined. Larvae widely different in appearance produce 

 adults which, according to the published keys, have been assigned to one species, and larvae which 

 are superficially very similar produce adults which are very different in many characters. In 

 this list no effort has been made to correct synonymy or verify identifications. (Roh.)
