Of the British jumping spiders, E^iblemum scenicum, a species 
which lives in the crevices of walls, is the most frequently met 
with. It is often to be seen wandering about in the sunshine in 
search of prey. 
It is to this family that the majority of the ant-like spiders 
belong. In the principal genus Myrmaraclnne there are more than 
eighty species, which are distributed over the temperate and 
warmer regions of the world. They often mimic particular 
species of ants, 
resembling them 
closely in form and 
colour ; their gait 
also is very ant-like, 
and they habitually 
run in the zigzag 
fashion of an ant 
pursuing its prey. To 
complete the decep- 
tion, the legs of the 
first or second pairs 
in some species are 
held up in the air 
so as to simulate 
the antennae of the 
insect. The family 
is cosmopolitan in 
distribution.

semblance to the 
spiders, but may be easily distinguished from them by their having 
both the cephalothorax and the abdomen distinctly segmented and 
by the absence of spinning mammillae. The “ cephalothorax 
(prosoma) is covered by three plates. The front one of these, 
which represents the terga of the first four somites, is of large 
size and bears a pair of median eyes and obsolete lateral eyes. 
The ventral surface of the fourth cephalothoracic somite bears a
