above downward, the lower part being wider than the upper. 
The highest point is at the dorsal eyes, there being a fall in 
both directions, that of the cephalic part, being steeper than 
the thoracic. The front half of the thoracic part is very full 
and convex on top, giving a rounded upper surface, while the 
second half slopes off abruptly. The quadrangle of the eyes 
occupies nearly one-half of the cephalothorax, is only one-fifth 
wider than long, and is about equally wide in front and be¬ 
hind. The front row of eyes is strongly curved downward. 
The middle are less than twice as large as the lateral, and 
all are subtouching. The eyes of the second row are larger than 
is usual in this family, and are placed nearer the first than 
the third row. The third row is plainly narrower than the 
cephalothorax. The falces are short and vertical, the lower 
margin being armed with several teeth. The sternum is rather 
long, is contracted in front and behind, and truncated in front. 
The first coxae are separated by the width of the labium which 
is as wide as long. The palpus has all the joints short, the 
tarsus being palette-shaped. 
The large eyes of the second row bring this genus into re¬ 
lation with several general which Simon groups under Boetheae s 
Cocalodeae , Cocaleae and Lineae, but Boethus and Portia have 
the first row of eyes curved upward. Cocalodes is quite differ¬ 
ently shaped, resembling Lyssomanes; Cocalus and Phaeacius 
have abnormally long spinnerets, and in Linus the thoracic part 
falls in one very steep slant, from the third row of eyes. 
The type of Sonoita is a new species from] South Africa.

$. Length 5 mm. Legs 4312, the first pair a little the stout¬ 
est, with a ridge of stiff spiny dark hairs under the tibia. 
Our single specimen has been rubbed nearly bare. The dark 
cephalothorax shows some patches of white hairs around the 
eyes and on the side's, and brownish-white hairs grow thickly 
on the clypeus, on the broadened upper surface of the palpus,
