times as long as face, inclined backward, a little diverging; fang 
weak. Maxillae slightly diverging, enlarged and rounded at ex¬ 
tremity. Labium one-half as long as maxillae, as wide as long. 
Sternum nearly as wide as long, oval, projecting between anter¬ 
ior coxae. Anterior coxae separated by nearly the width of the 
labium. Legs of the first pair a little stoutest. Femoral, pat- 
ellary, tibial and metatarsal spines on the four pairs; those on 
metatarsi of the fourth extending to base. 
Cephalothorax brown with a lighter central longitudinal band 
in thoracic part, in the midst of which is a spot of white hairs; 
the eyes are placed on black spots; the anterior part of the ceph¬ 
alic plate, the lower sides, and the clypeus are covered with 
white hairs; the lower margin is black. Abdomen brown, with 
a curved white basal band and a central wide white longitudinal 
band which is often indistinct in the anterior part, and is in¬ 
terrupted behind by a slender brown transverse curved band; 
this middle band gives off on either side two short white spots 
which are longer than wide, one in the middle of the first half, 
the other, oblique, just in front of the spinnerets. Venter dark 
brown or black with a white band behind and on the sides. 
Palpi yellowish-brown excepting the last two joints which are 
black, with black hairs. Falces, mouthparts, sternum, coxse and 
legs, reddish brown. 
United States. Several examples. 
We include this species, since it was described by Keyserling 
as belonging to the United States, although Mr. Banks is pro¬ 
bably correct in thinking that it is from the West Indies.
