PODOCERIDES. 
415 
Subfamily— PODOCERIDES. 
Superior antennae shorter than the inferior. Inferior 
antennae stouter than the superior. Posterior pair of 
pleopoda furnished with hook-like spines. 
The species of this subfamily have the superior pair 
of antennae less robust than the inferior. The inferior 
appear to be always used as legs in climbing, and are 
generally strong, sometimes forming a very powerful 
organ. This latter appendage is frequently thickly 
fringed with hairs, which in some instances, towards the 
extremity, stiffen into spines which are curved at the 
apex into strong hooks. 
The posterior pair of caudal appendages are always 
furnished with more or less perfect hooks, and in some 
genera the short middle tail-piece also. 
They generally build their abodes with materials col- 
lected in the vicinity, either in the form of nests or 
tubes.
