The species name is a belated tribute to Mr. H. S. Barber's deep 

 interest in insects, and to his careful and sometimes inspired studies. 

 The type specimen was collected in his younger years, in his favorite 

 spot. It remained unnoticed for more than half a century, until after 

 his death. Some of his other contributions have had a similar history.
