 Subgenus Xanthocypus Muller, 1925, p. 41. 



This rearrangement is of course based on the genotypes. I have 

 depended on the Bernhauer, Schubert, and Scheerpeltz catalogs for 

 the relationships of the species designated. Of the above the geno- 

 types are as follows: Of Oc7/pus, Staphylinus cyaneus Paykull = (9<?y- 

 pus cyaneus (Paykull) (original designation) ; of Anodus, A. falcifer 

 Nordmann (designated by Tottenliam, 1939) ; of Alapsodus, Anodus 

 falcifer 'Nordma\m=Alapsodus falcifer (Nordmann) (original 

 designation) ; of Goerius, /Staphylinus olens Miiller = Goerius olens 

 (Miiller) (designated here) ; of Rhagochila^ R. inderiensis Mot- 

 schulsky (monobasic) ; of Matidus, M. forflcularius Motschulsky 

 (monobasic) ; of Tasgius^ Staphylinus ruflpes Latreille = Tasgius 

 Tufipes (Latreille) (monobasic) ; of Pseudocyjms, Staphylinus mus 

 'Bru\le= Pseudocypus mus (Brulle) (designated by Tottenham, 

 1939) ; of Parocypus, Staphylinus (Parocypus) dehradunensis Bern- 

 hauer (monobasic) ; of Protocypus, Staphylinus {Protocypus) 

 fulvotomentosus Eppelsheim (monobasic) ; of Aulacocypus^ Ocypus 

 glonosus Sharp = Aulacocypus gloriosus (Sharp) (designated here) ; 

 of Neotasgius^ Ocypus hrcvlcoimis Weise = Neotasgius hrevicomis 

 (Weise) (monobasic) ; oi Xanthocypus, Ocypus weiseiHavold = Xan- 

 thocypus weisei (Harold) (monobasic). 



In addition to these the name Trichoderrna Stephens has been listed 

 as a subgenus of Staphylinus. Its type is Staphylinus murinus Lin- 

 naeus = Trichoderrna murinus (Linnaeus) (designated by Westwood, 

 1838). (The designation of nehulosus Fabricius by des Gozis, 1886, is 

 therefore invalid.) Since murinus is likewise the type of Ontholestes 

 Ganglbauer, 1895 (designated by Tottenham, 1940), these two are 

 isogenotypic. Trichoderrna^^ being the oldest name, is to be used 

 for the genus containing murinus. 



It will be noted that the true genotype of Staphylinus is also the 

 type of Creophilus. This means that the name Staphylinus should 

 be applied only to maxillosus and its allies (now known as Creophilus) 

 and that the genus including erythropterus., etc., must take a later 

 name. Several names are available for this, but none later than 

 Ou^hemus des Gozis neecl be considered. 



However, to most students of this family and to many other coleop- 

 terists, this transfer of the name Staphylinus to another genus, the 

 suppression of Creophilus., and tlie introduction of a newer name for 

 the large genus now considered the type of the family Avill seem to 

 be an unnecessary change of established names. Rather than make 

 this decision in the present paper, I am using Creophilus and Staphy- 

 linus in the sense of the Junk Catalog and leaving a final decision for 

 a more propitious moment.
