The species keys to P. culicijormis (Linneaus) in Johannsen (1952). 

 Although I have not examined Johannsen's material, it is most 

 probably referable to P. denticulatus , new species, and not P. culici- 

 jormis (Linneaus). The male genitaha offers a diagnostic character- 

 istic in the presence of the conspicuous denticles terminating the 

 median internal "strut." 



The following are the females of P, freemani, new species, and 

 P. denticulatus, new species. I cannot separate them with any 

 certainty.
