fang, which is nearly as long as the falx. Both margins have 
numerous teeth, those on the upper being longer. The ster¬ 
num is long, pointed behind and truncated in front. The first 
coxae are separated by a little less than the width of the labium, 
which is very long, plainly longer than wide. The maxillae 
are long and narrow, and are excavated, the wider distal end 
being connected with the base by a neck. The legs are all 
slender, the third and fourth pairs unarmed. There are six 
pairs of long spines under the tibia of the first and three pairs 
of short ones under the tibia of the second, while both legs have 
two pairs under the metatarsus and are provided with lateral 
spines. The patella of the first leg has one small spine below. 
The first leg is longer than the second by the tarsus, metatarsus 
and half the tibia. The pedicle is not visible from above. At 
the end of the tarsus of the palpus are two small spines. 
The cephalothorax and the front part of the abdomen are 
covered with light yellowish hairs. A wide, glistening, dark 
band crosses the abdomen, its front edge being a little in front 
of the middle, and behind this hairs of a lighter yellow than 
those in front extend to the spinnerets. All the legs are yellow. 
The falces are slightly rugose and have iridescent coppery re¬ 
flections. 
Two males, from Sarawak. 
The sternum of this species is not so pointed as is usual in 
Myrmarachne.

The integument is black, and in our specimen the only hairs 
remaining are some white ones which thinly cover the anterior 
sides of the cephalothorax and the clypeus. The horizontal 
falces are flattened above and rugose, narrowest at the proxi¬ 
mal end, with a spine above at the inner distal end. The in¬ 
ferior margin has numerous small teeth, and the superior mar¬ 
gin several larger ones. The first legs have the coxa and tar¬ 
sus light-colored, thei trochanter medium brown, and the other
