This species agrees with the West African P. chevalieri in having the 

 claws of the second maxillae completely pectinate, the median arc of 

 the labrum armed with true stout teeth abruptly differentiated from 

 the lateral ones, the pleurite of the second maxillary segment pro- 

 duced forward mesad of the segmental pore to the coxosternum with 

 which it is fused, the pore being thus completely surrounded, the 

 ventral pores arranged in a submedian circular area on the sternites, 

 and in having the pores of the last coxopleurae composite. 



The teeth of the median arc in the type number fifteen as against 

 twenty in P. chevalieri. The pleurite of the second maxillary somite 

 is differently formed, extending farther caudolateral as a more dis- 

 tinctly separated lobe and with the tongue projecting forward on the 

 mesal side of the pore narrower. The cephalic plate is proportionately 

 longer, the length to width being as 5:4. The cephalic plate in the 

 type extends over the edge of the basal plate, and the first tergite is 

 drawn much forward over it, the exposed portion being very short. 

 In a young paratype (M. C. Z., 1,874), however, the basal plate is 

 wholly free and long and the prebasal plate is exposed. The femuroid 

 of the prehensors is armed on the mesal side at the distal end with a 

 stout, strongly chitinous tooth. 



The last coxopleurae are densely shortly hairy as in P. chevalieri but
