also double, at the darkened end of the metatarsus, the prox¬ 
imal end of the metatarsus and the tarsus being white. In 
the third and fourth legs the metatarsus is much longer than 
the tarsus. The venter is dark. The sternum is sometimes 
all pale, but is usually pale in the posterior third and inky- 
black in front. Looked at from below, the coxae, trochanters and 
femora are pale, with an iridescent black streak along the front 
side. From above, a similar black streak is visible along the 
back sides of the same joints. 
The males of V. petulans and V. arrogans may be distin¬ 
guished by the metatarsi of the first legs, which in the former 
species are darkened and fringed at the distal end, while in 
arrogans they are pure white. In petulans, the femur, patella 
and tibia of the palpus are pale, while in arrogans these joints 
nre reddish-brown. 
Viciria moesta sp. nov. 
A white female, with the metatarsus in the third and fourth 
legs nearly twice as long as the tarsus. The cephalothorax is 
very pale yellow, with the eyes on black spots and a dark spot 
in the middle of the cephalic square, while the abdomen is 
white, with two slender, longitudinal reddish bands converg¬ 
ing toward the spinnerets. 
$. Length 9 mm. Legs 4312, first and second a little the 
stoutest. 
The front row is straight, with the middle eyes slightly sep¬ 
arated from each other and more widely from the laterals, 
which are about half as large. The second row is nearer ..the 
first than the third, and the third is plainly narrower than the 
cephalothorax at that place. The falx has one tooth on the 
lower margin and two, near together, on the upper. 
In the first and second legs, the tibine have 3-3 spines with 
laterals, and the metatarsi 2-2 without laterals. The third 
and fourth legs have many spines. 
In our specimens the sides of the cephalothorax are rubbed 
bare. The color is very pale, with dark red or black spots 
around the eyes and in the middle of the cephalic plate, which
