 wider than long; strongh' narrowed cephalad. 



Middle piece of labrum triangular, not subtrapeziform as in P.froggatti, and 

 also somewhat larger than in the latter species. The upper bars of the fulcra 

 more slender, much less narrowed ectad than in froggatti. 



Lappets of outer branch of first maxiUae longer than in the latter species. 



Second maxillae similar; pores more freely open on mesal side. First legs 

 ver}' much smaller than the second which are equal in length to the third.

 second of similar form but the others soon becoming strictly circular. 



Ventral plates coarsely punctate. 



Last ventral plate long and narrow, obviously longer than wide. Coxo-
