77(76). Form subparallel, lamina? meeting at apex, not overlapping. 



P. vionticola, n.sp. 

 X. 7S(31). Anal forceps extremely short, not meeting at apices, which 

 alone are visible; anal excavation shallow. 

 79(82). Abdominal fascicles present, small and situated far apart. 

 80(81). Elytral interstices granulate for the most part in double series. 



P. ahnormis Macl. 



81(82). Elytral interstices granulate for the most part in single series. 



P. assimilis, n.sp. 



82(79). Abdominal fascicles absent. P- perlata, n.sp. 



J^otes on Table of the Species.— The Roman numerals represent 



what, in my opinion, may be regarded as distinct groups of 



species. 



group v.— The inclusion of P. Mastersi in this group is some- 

 what arbitrary; the costate elytra, peculiarly shaped forceps, and 

 the absence of the interforftcular process might be sufficient to 

 entitle it to a group of its own. 



P. flavosetosa also differs from the typical members of the group 

 in the absence of the interforficular process. 



The other members are all extremely closely allied. 



Group viii.— P. metasternalis occupies an anomalous position; 

 probably further research will show it to be one of a definite 

 group, allied in some respects to the P. forficulata-gxou\).
