The cephalothorax is wide, and moderately high; the thoracic part 
is longer than the cephalic. It is black, entirely covered with short 
whitish brown hairs, and longer, sparse, black hairs, the black hairs 
all pointing forward, thickest just above the anterior eyes, and form- 
ing two tufts on each side, one just back of the lateral eye, and one 
between the small median and the dorsal eye. The sides are reddish. 
The lower narrow margin is white. 
The quadrangle of the eyes is a third wider than long, and much 
wider behind- The dorsal is as large as the lateral eye, and is on a 
line with it. The small median eye is on a line with their upper 
borders, and is nearer the lateral eye. The anterior row of eyes is 
slightly curved, a straight line from the top of the middle, cutting the 
upper borders of the lateral eyes. The lateral are placed further 
back on the face than the middle eyes. The middle eyes are slightly, 
the lateral more widely, separated. The lateral are a little more than 
half as large as the middle eyes. This row of eyes is placed below 
the edge of the cephalothorax. The elypeus is one-half as wide as 
the middle eyes and vertical, the upper part is reddish and almost 
bare; the lower edge is fringed with thick, short, snowy white hair, 
which falls over the base of the falces. 
The palpus is long and pale, with white hairs. 
The falces are very robust, vertical, and moderately long. Their 
color is bright iridescent green. 
The maxilla; are short, thick and rounded, light brown in color. 
.The lip is half as long, rounded, and also light brown. 
The sternum is brownish, somewhat iridescent, with white hairs* 
The relative length of the legs is 4, 1, 2. The lirst pair is the 
stoutest. In color they are reddish, with some white and black hairs. 
There are tibial and metatarsal spines on the four pairs, those on 
the metatarsi of the fourth extending to the base.
