 Fijis: Xadarivatu (W. M. Mann). 



General color chestnut-brown, the first tergite contrasting in being abruptly 

 paler, fulvous in whole or at least its anterior part. Legs fulvous. Antennae 

 brown. 



The second tergite on each eide extends forward as a rounded lobe a little 

 overlapping the lower end of the first tergite and the caudal border of the 

 cardo of mandibles. The metazonites elevated much above prozonites; 

 between legs and lateral thickenings at level of pores densely finely granular 

 with granules of uniform size and non-setigerous ; the dorsal region also 

 densely granular but in addition to the small granules with mostly seven 

 transverse rows of larger setigerous tubercles, the setae moderately long and 

 distally acute. Surface beneath pores not at all elevated and the lateral 

 thickening not projecting at all over pleural region, the surface evenly con- 

 tinuous. Anal tergite triangular; the cauda subcyhndrical, projecting widely 

 beyond the anal valves, obscurely decurved, the tip narrowly truncate; 

 dorsally densely granular like the other tergites, with transverse series of 

 larger setigerous granules or tubercles. Valves densely granular, the margins 

 strongly elevated but not sharply limited by furrows; each with two larger 

 setigerous tubercles. 



In the male gonopods the caudal ectal edge of the femoral division projecting 

 strongly caudad in a triangular plate or process. The distal portion running 

 mesad, and widely overlapping the other gonopod Avith which it fits closely 

 together, a stout conical i)rocess at base in front of each gonopod. The 

 telopodites at base where they are in contact between the coxae with mesal 

 edges strongly dentate, the teeth interlocking, these teeth visible only when 

 the gonopods are somewhat separated from each other. 



Length (female), to near 14 mm.; width, 1.4 mm. The males smaller than 

 the females. 



FiJiODESMUS, gen. nov. 



In general appearance closely resembling Phlyctodesmus but the 

 granulation much finer, obscure or absent on the anal valves. A 

 readily noticed difference is that the pores are distinctly though not 

 strongly elevated, the rim of the elevation fringed with the short hairs. 

 The gonopods very different in appearance, the coxae very large, the
