long and slender, the first and second legs having, besides lat¬ 
eral spines, 3-3 nnder the tibia and 2-2 under the metatarsus. 
The cephalothorax is yellow with black tubercles at the sides 
of the eye-region. The hairs on the cephalic plate and around 
the eyes of the second and third rows are yellow with an in¬ 
termingling of red, and those around the front eyes and on. the 
clypeus are white. The abdomen is light yellow with an iri¬ 
descent band down the middle, on the edges of which, in front, 
are dark streaks, and, further back, four pairs of black spots. 
The sides are covered with glistening yellow hairs, with a little 
red near the dark spots. The spinnerets are jet black. The 
clypeus, falces, palpi and legs are yellow, the legs tinged with

This is a dark olive-green species, beautifully marked with

S. Length 5 mm. Legs 1342, first pair much the longest. 
The cephalothorax is rather long and moderately high, con¬ 
vex above, inclined forward from the second row of eyes and 
falling very slightly behind the dorsal eyes through two-thirds 
of the thoracic part, after which the descent is steep. It is 
widest in the middle, rounding gently in front and behind. 
The quadrangle of the eyes is a little wider in front than be¬ 
hind, occupies one-half of the cephalothorax and is one- 
fourth wider than long. The front eyes form a very slightly 
curved row, the lateral being half as large as the middle and 
a little separated from them. The second row is nearer the 
first than the third, and the third is narrower than the cephalo¬ 
thorax. There are no tubercles nor depressions. The sternum 
is rounded, truncated in front, and is nearly as wide as long. 
The cox£e are separated by the width of the labium, which is 
longer than wide. The falces are stout and projecting, with 
long white hairs. The lower margin has one stout tooth, the 
upper two, one larger than the other. The spinal armature
