 of D. robusta. The inner and outer margins are each 

 furnished with one seta, while the apex has three (fig. 18). 

 Caudal furca equal to the combined lengths of the last 

 two abdominal segments. 



Remarks. — This species ' is easily distinguished from 

 D. inopinata by the structure of the fifth pair of feet and 

 the longer caudal furca.
