 not extending behind trochanteres II, in its posterior half 

 nearly circular. Posterior dorsal shields very small; 

 their outline is about that of three circles touching each other. 

 Hairs. To the sides of the anterior shield, near trochanteres 

 II, a pair of hairs as long as the shield. Inward of this pair 

 a pair of minute ones. Near the edge at the greatest width 

 of the body a pair of minute ores. Between the anterior 

 shield and the nephridial openings two rows of three minute 

 hairs each. Between the nephridial openings and a little more 

 backward a pair of ditto. Behind the nephridial openings a 

 pair of ditto. And just before the posterior shields a pair 

 of ditto. 



Ventral side (Fig. 9). No median subcapital tubercle. 

 Epiraera I free ; epimera II as long as epimera I. Epimera III 

 scarcely longer than trochanter III. Epimera IV a little longer 

 with proximal external epimerite and with distal external
