The cephalothorax is 
high; the cephalic part is 
yi shorter 
than the thoracic; it is plane and much inclined, with vertical 
sides, and is not limited by a depression. The thoracic part is 
convex, and slopes backward from the dorsal eyes; its sides are 
rounded. The cephalic part is brown, glabrous, with a central 
spot of white hairs; the eyes are situated on black spots. The 
thoracic part is darker brown, pubescent, also with a central 
white spot. A band of white hairs, on each side, passes from 
the anterior lateral eye to the posterior margin; below these 
bands the sides are dark brown. 
The quadrangle of the eyes is wider than long, and equally 
wide in front and behind. The anterior row is straight; the 
lateral are placed a little further back than the middle eyes, and 
are as large; they are very slightly separated from the mid¬ 
dle eyes, which are touching. This row is visible when looked 
at from above. The eyes of the second row are half way between 
the dorsal and lateral eyes. The dorsal eyes are as large as the 
lateral, are placed on the margin of the cephalothorax, and are 
equally distant from each other and from the lateral borders. 
There is no frons. 
The height of the clypeus is equal to ]/o the diameter of the 
large middle eyes; in direction, it is vertical. 
The falces are stout, long, inclined forward, diverging; the 
fang, which has. a slight bend in the middle, is nearly as long 
as the falx.
