There is a female from Durban (F. Muir), which has an entirely

 wholly black ; abdomen black, with the third and fourth segments

Head black, strongly wrinkled, covered with short and sparse 

 whitish pubescence, which does not conceal the ground-colour of 

 the face ; the frons, as far as the transverse furrow, and the upper
