Hyllus natalii sp. nov. 
Plate XXIII, figs. 4, 4a, 
?. Length 12 mm. Legs 3412, all stout and rather-hairy. 
The cephalothorax is reddish-brown with black spots around 
the eyes. The sides are thinly clothed with whit© hairs and 
there seems to have been a median white band on the thoracic 
part. On the clypeus, falces and palpi are long whitish hairs. 
The abdomen is black with a whitish band down the middle, on 
which is a pattern in fine black lines. On each side, are three 
yellowish-white spots. The legs are dark brown, with a good 
many long white and black hairs. There are ridges of black 
hairs under the tibia in the first and second. The venter is 
black in the middle with a light band on each side. 
The dark venter in natalii and the light venter in moestus 
distinguish these two species from each other. In the female 
of perspicuus the venter is light with a dark line down the mid¬ 
dle, and in Treleavenii it is covered with silvery hairs. 
We have one female from Xatal, sent by Mr. Quekett, 
Modunda aperta sp. nov. 
Plate XXVI, figs. 9, 9a. 
S. Length 6 mm. Legs 1342, first heavily thickened. 
The quadrangle of the eyes is about one-fourth wider than 
long, is a little wider behind than in front, and occupies only 
two-fifths of the cephalothorax. In the type of this genus the 
quadrangle occupies about half of the cephalothorax. The 
cephalothorax is long, rather low, and very flat, the sides round¬ 
ing out slightly from in front backward and from above below. 
The first row of eyes is straight, the eyes being close together, 
the middle nearly three times as large as the lateral. The sec¬ 
ond row is a little nearer the first than the third. The third 
row is a little narrower than the cephalothorax. The sternum 
is attenuated in front. The anterior coxa? are separated by the 
width of the labium, which is about as wide as long. The
