GENERIC NAMES OF THE FAMILY STAPHYLINIDAE 313 



PLATYDRASUS [Error for Platydracus]. 

 PLATYDROMUS Fauvel, 1905c, p. 174. 

 Genotype : Platydrovius erosus Fauvel. 

 Fixed by : Fauvel, 1905c, p. 174, by mouotj'py. 

 Later citations : P. erosus Fauvel, by Lucas, 1920, p. 519. 

 PLATYGONIUM Motschulsky, 1845, p. 40. 



Genotype : Platygonium soulticeps Motschulsky. 



Fixed hy : Motschulsky, 1858, p. 649, by being the first species included in 

 the genus by name. (The species can be considered to have been validated 

 here by the characters listed under the genus.) 

 Later citations: P. sculticeps Motschulsky, by Lucas, 1920, p. 519; by Black- 

 welder, 1939, p. 120. 

 Discxission : This is not true monotypy, since the species was not originally 

 included. The emendation of the trivial name to sculpticeps apparently 

 cannot be justified on the basis of the original publication.
