which, is widened, with a shoulder on the outer side at the 
proximal end. 
Of oiivacea w T e have a single male!, from Sarawak. 
Erasinus gracilis sp. nov. 
In this species the cephalothorax is dark with white marks, 
the abdomen pale brown, and the legs light yellowish. 
6. Length 5.5 mm. Legs 3214, about equal in thickness. 
The cephalic part is high and convex, not inclined. The 
thoracic falls steeply from the dorsal eyes. The sides are 
nearly vertical in front but widen a little in the thoracic part. 
The quadrangle of the eyes occupies more than half the cephalo¬ 
thorax, is only one-fifth wider than long and is plainly wider 
in front than behind. The first row is straight, with the lat¬ 
eral scarcely half as large as the middle eyes, and a little sep¬ 
arated from them. The second row is halfway between the 
others, with a depression on the sides, behind. The third 
row is about as wide as the cephalothorax. The sternum is 
long, oval, truncated in front. The first coxse are separated 
by fully the width of the lip, which is wider than long. The 
faloes are directed obliquely forward. The upper margin has 
two teeth, the larger one being near the insertion of the fang. 
In the first and second legs the spines are 3-3 on the tibia and 
2-2 on the metatarsus, both joints having laterals. The meta¬ 
tarsus of the third has two circles and that of the fourth three 
circles. The tarsus of the palpus is elongated, exceeding the 
patella and tibia together, and has a long, black, whiplike 
apophysis which passes under the tibial apophysis. The bulb 
is cone-shaped with its base at the cup of the tarsus. 
The cephalothorax is darker than the abdomen. There is 
not much left on our single specimen, but the cephalic part 
and the entire abdomen seem to have been covered with golden 
iridescent scales. There is a white band on each side in 
front, a white spot between the dorsal eyes, and a wide, some¬ 
what crescent-shaped white band halfway down the thoracic 
slope. The falces are reddish-brown, and the legs pale yellow, 
lighter than the palpus. 
One male, from Sarawak.
