 History). 



This species needs no comparison with any of the known 

 species of the genus. Together with the last-described 

 species, E. iynava, the present form miist be considered an 

 aberrant member of the genus Eriopttra, and yet there are 

 no sufficient tangible characters on which to remove either 

 from this large and somewhat heterogeneous group.
