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.
