Some individuals are considerably darker than others and there is some variation 

 in size. The anterior legs are remarkably long and slender, their metatarsus being

 suddenly dilated on their basal part than is usual in the allied forms. The posterior 

 tibiae are very long, and the spines on each side very short.
