An aberrant species to refer to this grouj), but which will fit in nowhere 

 else. It is perhaps entitled to a subgroup, including it alone. With its 

 structural peculiarities the color is unique. The S clasper is practically 

 like this group, but somewhat shorter and rather more robust. The 

 whole appearance is more heavy or robust than any other species, and 

 the primaries are wider. The 9 differs in the greater proximity of the 

 tranverse lines and in having the orbicular larger.
