Pancorius fasciatus sp. nov. 
$. Length. 8.5 mm. Legs 1342, first a little the stoutest. 
The cephalothorax is high and convex, rounding up from 
the first to the third row of eyes, and then down, in an equal 
degree, through two-thirds of the thoracic part, when the de¬ 
scent becomes steeper. The sides are widely rounded, as in 
males of Thyene the widest point being behind the dorsal 
eyes. The cephalothorax is plainly narrower above than be¬ 
low. The quadrangle of the eyes occupies less than two-fifths 
of the cephalothorax, is one-fourth wider than long, and is 
slightly wider in front than behind. The front eyes are large 
and close together, the middle being nearly twice as large as 
the lateral. This row is curved upward. The cephalothorax 
is depressed behind the eyes of the second row, which is half¬ 
way between the others. The third row is plainly narrower 
than the cephalothorax, the eyes being elevated. The sternum 
is rounded, not much longer than wide, and truncated in front. 
The coxse of the first legs are separated by more than the width 
of the labium, which is longer than wide. The maxillse have 
long apophyses at the outer comers. The falces are vertical 
and very wide, with long, strong fangs. They have one tooth 
on the upper and one on the lower margin. The armature 
of the first and second legs is 3-3 on the tibia and 2-2 on the 
metatarsus, with stout, large lateral spines on both joints, those 
on the metatarsus being so low down as almost to form a third 
inferior pair. 
The specimen which we have shows a black iridescent ceph¬ 
alic plate, and a thoracic part of reddish-brown. Yellowish- 
white hairs form a band down the middle of the thoracic part, 
and a few hairs of the same color are left around the eyes. 
Long white hairs border the edge of the clypeus and are scat¬ 
tered over the falces. The sides of the abdomen are dark and 
seem to have been covered with deep yellow hairs. Down the 
middle is a wide band of pale yellow hairs, which is somewhat 
arrow-shaped in front, and is outlined on the sides with black. 
The legs are reddish-brown, the tarsi lighter in color than the
