Pseudamycus amabilis sp. nov. 
This is a large and distinctly marked female. The legs 
are yellow, the cephalothorax reddish-yellow with red and yel¬ 
low hairs on the eye-region. The abdomen has a wide! light 
hand down the middle. The anterior sides have dark streaks 
on a light ground, and the posterior sides are dark brown, each 
marked with a conspicuous white or yellow band. 
$. Length 9 mm. Legs 3124, first and second pairs a little 
the stoutest. 
The cephalothorax slopes rather steeply in both directions 
from the dorsal eyes and is wider in the thoracic than in the 
cephalic part. The lateral eyes of the first row are more than 
half as large as the middle eyes and are a little separated from 
them. The eyes of the second row are about halfway between 
the lateral and the dorsal eyes and are separated from the latter 
by a deep depression. The falx has one tooth on the lower 
margin and opposite to this, on the upper margin, two teeth, 
close together. 
The spines are long. The tibiae of the first and second leg's 
have 3-3 with laterals, and the metatarsi have 2-2 without 
laterals. On the third and fourth legs they are numerous and 
strong. 
In our specimens the sides of the cephalothorax are rubbed 
bare, but all the eyes are surrounded by yellow hairs, which 
also grow thickly on the cephalic square. A band of bright 
red hairs runs along the side of the cephalic plate from the lat¬ 
eral to the dorsal eye, and there is a red patch behind the dor¬ 
sal eye. The hairs on the clypeus are white. The faloes are 
reddish, the palpi pale and the legs yellow. The abdomen has 
a band of yellow hairs down the middle which has a brown 
streak in the middle, in front. The anterior sides are marked 
with lines of yellow and brown hairs. The posterior sides are 
covered with dark brown hairs marked with a pair of white 
or bright yellow bands, and, further back, a pair of yellow bars. 
The venter Is lighficolored, with a large dark patch in the 
middle, upon which are two longitudinal lines of white spots. 
We have four females from Sarawak.
