Description of a Bemarhahle Tennitophilous Isopocl. 411 



Abdominal segments eacli with a transverse row of conical 

 tubercles above, the median tubercle from the second segment on 

 being absent ; segments I and II very short, III and IV with the 

 epimera continuous with and similar to those of the thorax, except 

 that the tubercles are absent. 



Antennce with the second segment lobate at base externally, sub- 

 equal to the fifth in length, the third or fourth segments subequal 

 but together longer than the fifth ; flagellurn about as long as the 

 fourth segment of the scape and much shorter than the fifth, its 

 basal segment forming half, its second segment a quarter, of the whole 

 length, the segments becoming successively narrower, the apical 

 segment very minute. 



Length in millimetres (to apex of telson) 5*8 ; width of fourth 

 segment 5 ; of head 3 J. 



Since the above went to press I found four other specimens of 

 P. hraunsi at Matjesfontein, Cape Colony, under a stone in the 

 galleries of a dark-coloured Hodotermes (evidently H. mossamhicus).
