costa just before the extreme apex; these black markings occupy 

 more of the wing than does the white ground-colour ; veins testaceous 

 in the white portion, black in the black. Legs short and very stout, 

 deep black. Abdomen reddish brown, more obscure in the apical 

 half; the two basal segments show a trace of the black dorsal thoracic 

 vitta ; the basal segments with short white pubescence.

 any indication of locality ; it is possibly African.
