The flagellum is composed of eleven articles, with the first article 

 slender, equaling- in length the following- article. 



The second pair of antennas extend to the 

 fourth epimeron; the flagellum is composed 

 of twenty-four articles. 



The first segment of the thorax is slightly 

 bisinuate on its dorsal surface. The epimera 

 are rather narrow; the posterior angles of the 

 posterior epimera are acutel}" produced; the 

 last epimeron extends to the middle of the 

 first segment of the abdomen. 



The prehensile legs are slender, smooth; the 

 basis is rather narrow; the anterior ungula? are 

 rather short, somewhat incurved; the poste- 

 rior ones are somewhat larger. 



The ambulatory legs are produced, slender, 

 and furnished with scattered spines. 



The first segment of the abdomen is largely 

 concealed. The last segment is Ungulate, 

 posteriorly obscurely crenulate, smooth abov^e. 

 The uropoda are rather long; the inner branch 

 is much longer and wider than the outer branch ; 

 both branches are posteriori}- attenuated and 

 obscurely crenulated. 



Length 11.5 mm.'*
