We have one very dark female from Durban in which the 
markings are perfectly preserved. The cephalothorax is black 
with narrow white bands around the lower sides, which do not 
meet behind. There is a white bar just below each dorsal eye:, 
and a median white band beginning between the dorsal eyes 
and passing back for two-thirds the length of the throaeic part. 
There is a white spot near the middle of the cephalic part, and 
a white patch in front of each dorsal eye. Over the first row 
of eyes are some grayish white hairs. The clypeus has whitish 
hairs and under each lateral eye are three white lines alter¬ 
nating with dark lines. The abdomen is velvety black with a 
white median spot at the front end and a pair of longitudinal 
snow-white lines on the anterior part of the dorsum. Behind 
this is a series of four white spots. In some lights the abdomen 
shows green reflections. Each side has a short oblique white 
line in front and a scalloped white band behind. The legs are 
dark with longitudinal white lines. 
Our other specimens, which are more or less rubbed, have the 
black intermixed with dark reddish-brown. In the male the 
white bars below the dorsal eye are continued and meet on the 
thoracic part. The abdomen is dark brown, or black and has a 
broken white band down the middle, which, in the females, 
forms white chevrons alternating with black ones. The falces 
are heavy, projecting, dark reddish-brown in color, with some 
short white hairs. The palpus is dark, that of the female hav¬ 
ing a. bunch of white hairs at the tip. 
Besides the female from Durban we have three specimens 
from Mashonaland and two> from Zanzibar, the latter being the 
larger.
