plate lighter than the rest. The lower margin is black, and 
above this is a wide bright band of snow-white hairs, around 
the sides and back and across the clypeus. Higher up is a 
band of red hairs which borders the cephalic plate, surrounds 
all the eyes, and forms a crescent just behind the dorsal eyes. 
The few hairs that are left on the cephalic plate, in our speci¬ 
men, are white. The falces are reddish-brown with long white 
hairs. The palpus is pale except the tarsus, which is tinged 
with red. The abdomen is broken and rubbed. There is a 
tuft of white hairs in front, and it seems to have been white in 
the middle and at the end, with yellowish sides. The first and 
second legs are reddish-brown with black hairs on the femur 
and tibia and white hairs on the patella. The first has a very 
light short fringe of black hairs under the patella, tibia and 
metatarsus. The other legs are lighter-colored and have a 
band of black and a band of white hairs on the femur.

Afiola gen. nov. 
This genus is near Pseudamycus , but the slope in both di¬ 
rections from the dorsal eyes is not so steep as in that genus. 
The cephalotkorax is wider behind than in front and a little 
wider below than above. The quadrangle of the eyes is one- 
fourth wider than long, occupies a little less than one-half of 
the cephalothorax, and is slightly wider behind than in front. 
The first row is straight, the lateral being separated from the 
middle eyes and two-thirds as large. The second row is half¬ 
way between the others. The dorsal eyes are large, and are 
placed on tubercles, so that a depression separates them from 
the eyes of the second row. The third row is a little narrower 
than the cephalothorax. The front coxae ar separated by only 
the width of the labium, which is a little longer than wide. 
The maxillae have a sharp point at the outer side. The sternum 
is rather narrow and is truncated in front. The falces are 
vertical, wide and short, with one stout tooth on the lower 
margin, and two, close together, on the upper. The tarsus of
