 scarcely traceable below the submedian fold, where there is a faint sug- 

 gestion of a very slender dark streak uniting the median lines. Sub- 

 terminal line vague inwardly and scarcely defined by a paler following 

 shade; very irregular, but not dentate. There is a slender black ter- 

 minal line which is sometimes broken. Orbicular round, moderate in
