teeth. The margins of the three first segments after the 

 head are bifurcate. The antei-ior fork of the first bears a 

 stout seta^ the posterior one^ as well as both processes 

 of the two following segments^ bear foliated appendages 

 like those of the abdominal segments. 



The lateral expansions of the middle segments stand 

 out at right angles to the longer axis of the body, but 

 they gradually turn round, so that those of the terminal 

 segment point backwards, only diverging a little from 

 one another. Besides the foliated appendage, this seg- 

 ment bears at each extremity, a stout, rodlike, not very 

 long seta. 



The accompanying figure (Plate XIII) obviates the 

 necessity for any detailed description. 



The antennae are four-jointed, short and tapering. The 

 third segment, covmting from the base, bears three small 

 hairs, and a strong slightly-curved process, which is 

 somewhat longer than the apical segment. The terminal 

 segment bears a tuft of hairs, and a strong spine at the 

 apex, and a hair at each side near the middle. None of 

 the hairs on this segment taper to a point, but all end 

 somewhat abruptly. 



The legs are short, and all six similar to one another. 

 The claw is simple but strong. The segment preceding 

 it is slightly conical, and bears several curious pairs of 

 spines, or rather perhaps bifurcate spines, as well as a 

 few hairs. 



There are no anal styles.
