Paramarpissa tibialis F. O. P. C., which Simon suggests may be 
this species, equals Pseudicius piraticus. 
S $ . Length 4 mm. Legs 4132, first pair much thickened, 
especially in male. Met. 1 with 1 pair stout spines; none on 
tibia. 
The cephalothorax is dark, black on the eye-region and sides, 
thinly covered with white hairs which are slightly mixed with 
light-yellow. The very small, short falces, and the clypeus are 
very dark in color, the latter covered with white hairs. When 
wet the abdomen shows a branching dark line down the middle, 
the sides being covered with round whitish scales. In one fe¬ 
male the brown branching band becomes more solid, so that the 
upper surface is dark, with two short longitudinal white bands
