Genotype: Pseudothamiaraea 'brunnea Cameron. 

 Fixed by : C-ameron, 1923, p. 363, by monotypy. 

 PSEUDOTHINOECIA Bernhauer, lS99a, p. 20. [Subgenus of Ischnopoda.] 

 Genotype: Pseudothitwecia puellaris (Bernhauer) (Atheta).

 PSEUDOXANTHOLINUS Cameron, 1946a, p. 500. 



Genotype: PsetidoxanthoUnus sharpi (Broun) (Xantholinus) .

 xantholinus Cameron, of which sharpi had already been fixed as genotype. 

 Synonyms : 



Pabaxantholintjs Cameron, 1944f, p. 784. [Objective. Not Bern- 

 hauer, 1926.] 

 Notes : This new name was proposed in an unsigned note in the following 

 volume of the same journal. It is a reasonable assumption that Cameron 

 is the author of it. 

 PSEUDOXYPODA Cameron, 1939e, p. 429.

 Fixed by : Cameron, 1939e, p. 429, by monotypy. 

 PSILOTRACHELUS Kraatz, 1859, p. 124. [Synonym of Stiliderus.] 

 Genotype: Psilotrachelus crassus Kraatz. 

 Fixed by : Lucas, 1920, p. 555, by subsequent designation. 

 Later citations : P. crassus Kraatz, by Blackwelder, 1939, p. 121. 

 Synonyms : (See Stiliderus). 



Notes : The present disposition of this name is based on the study by Black- 

 welder (1939). 

 PSILOTRICHUS Luze, 1904a, p. 69. [Synonym of Misancyrus.'i 

 Genotype : Psilotrichiis elegans Luze. 

 Fixed by : Luze, 1904a, p. 69, by monotypy.

 PSYLLIUS Gistel, 1834, p. 9. [Synonym of Megarthrus.} 

 Genotype: Psyllius depress us (Paykull) {Staphylinus). 

 Fixed by : Gistel, 1834, p. 9, by virtual monotypy. 

 Discussion: Two species were listed by Gistel, but one was a manuscript 



name of Dejean. 

 Synonyms : ( See Megarthrus) . 

 PTATYDRACUS [Error for Platydracus]. 

 PTEROLOMA (See Appendix). 

 PTERONIUS Blackwelder, new genus. 



Genotype: Pteronius brachypterus (Fabricius) (Dermestes). 

 Fixed by : Blackwelder, here, by original designation. 

 Synonyms : 



Fboteinus of Latreille, 1810, p. 427 (not 1796, 1802). 

 Notes : The removal of the name Proteinus to the Nitidulidae because of the 

 heretofore unrecognized type fixation leaves the genus formerly known 

 as Proteinus without a name. The name proposed here is not a new name 

 in the ordinary sense but a new genus. 



In order to comply fully with the provisions of the amended Article 25, 

 it is stated that this genus is the one that is described by Ganglbauer in 

 1895, p. 757, under the name Proteinus.
