third and very slightly narrower at the apex itself; last 

 dorsal segment short, transverse, truncate posteriorly ; penulti- 

 mate ventral segment obtusely rounded ; last ventral segment 

 visible as a pair of triangular lobes just protruding. 



Forceps remote at the base, triquetre at the base itself, 

 arcuate, tapering and short, <$ ; $ unknown. 



This genus differs from Parisolabis in being much less 

 depressed and less dilated, and the last dorsal segment is by 

 no means narrowed. 



It approaches more nearly to Anisolabis than does Pariso- 

 labis, and represents the transition between the Brachylabidae 

 and the Anisolabidse. 



In the form of the abdomen and last dorsal segment 

 P seudisolabis approaches Anisolabis, but the antennas have 

 fewer segments, the second segment of the tarsi is longer, the 

 posterior margin of the metasternum is scarcely produced 

 between the posterior coxae, and the mesosternum is shorter, 

 relatively much broader, and truncate posteriorly.
