The spider is black with some reddish hairs in the eye-region, 
a central white longitudinal band from the front eyes to the spin¬ 
nerets, and wide white bands throughout the length of the sides 
of the cephalothorax and abdomen. The central band widens to¬ 
ward the end of the abdomen, where, in the female, it is marked 
by indistinct dark chevrons, and has a pair of transverse white 
bars extending from it. On the front part of the abdomen, in 
the female, the central band is divided by a dark line. The 
clypeus and front of the falces are covered with white hairs, the 
clypeus in the male, marked with an oblique red band under each 
lateral eye. The palpus is yellow with the hairs yellowish ex¬ 
cept on top of the femur, where they are white. The legs are 
gray, with gray hairs, the front face of the first, in the male, 
marked by a longitudinal dark line, most marked on the femur; 
this line is repeated, less distinctly, on the other legs. The 
venter has a long, dark, wedge-shaped mark. 
Mr. Banks has this species from Florida, and we have it from 
Florida and from Brownsville, Texas. It is found in all the 
warm regions of the world.
