Mr. W. L. Distant has kindly compared X. media rirura 

 with the type of Kamendaka and informs me that he cannot 

 separate these two genera. 



(1) K. saccliiir! mm (Mats.). 



^ Pygophor laterally compressed; ventral edge produced into 

 a long, pointed, median process about half the length of genital styles; 

 lateral edges slightly rounded; anal segment nearly as long as genital 

 styles, narrow, sides straight, slightly converging towards apex, anus 

 near apex, apex rounded; genital styles large, broadest about middle, 

 upper edge straight, lower edge convex, apex turned inward and up- 

 ward slightly. 



9 Last abdominal ventral plate producd angularly in middle. 



XlCERTA. 



(1) N. flexuosa (Uhler). 



Otiocerus flexuosus Uhler. 



This species has the median sectors in apical third of teg- 

 men, the first cnbital joining second, enclosing second cnbital 

 cell, therefore it comes into the Nicerta gronp and, except for 

 the more flattened antennae, is congeneric with N . cruenta. 



In Mr. Nitobe's collection there is a damaged male from 

 Mt. Ari near to this species bnt quite distinct. 



Mysidioides ]\rats.

This genus is near Ileroiia.r. In female specimens of ^1/. 

 sapporensis the vertex is narrow bnt truncate at apex, a slight 

 keel divides the vertex from face ; in the male the keels of face 

 meet at base, making the apex of vertex angular as in Neocyclo- 

 metopiim; the difference in the antennae of N. sordidiim is not 

 sufficient to establish a genus on.
