 Pfapsi legs much Bhorter and more slender than the second; the second legs 

 of intermediate Length. 



Ventral pores numerous and distinct; in a transverse hand m front of the 



caudal margin of plate, this band in the posterior plates tending to be divided 



at the middle line. 



Last ventral plate very wide, BUb1 rapeziform, the caudal margin a lit tit- 

 con ve\ i loxopleurae each with two large pits adjacent to lateral edge of the 

 ventral plate, each pit more or less doubled. Anal legs in the male moder-

Pairs of legs, sixty-one. 



Length, 30 mm.

Clypeal area present. Outer branch of first maxillae biarticulate, with- 

 out lappets; coxae fused at middle, also without lappets. Coxae of second 

 maxillae forming a narrow isthmus at middle in which a separating suture 

 is ^.till evident though weak; joints of palpus without processes, the claw 

 smooth. Middle piece of labrum small; teeth absent or indicated merely as 

 a few weak or obsolete crenulations. Prehensors extending well beyond front
