Synonymy. 



P. vicarius Pasc. = F. glaber Macl. = P. ater Blackb. = P. striato- 

 punctatus Boisd. C?). 



Having compared the type of P. glaher Macl., with specimens 

 of P. vicarius Pasc, (cotypes, fide Mr. Masters), I have no hesita- 

 tion in saying that the species are identical. There seems to be 

 little doubt as to the synonymy with P. ater Blackb. The 

 Macleay Museum specimens (cotypes) of P. vicaritts certainly 



* Species identified only from description. 



** P. agonus Pasc, is unknown to the author, and unrecognisable from 

 description, but evidently comes near 30. 



Macleay's Section ii., Subsection ii., is omitted here, having been revised 

 and tabulated by the Rev. T. Blackburn (Tiatis. Rov. Soc. South Australia, 

 1907, p. 290).
