arbitrary dlvisious, depending on the pccnliar ideas of indi- 

 vidnal authors." So here, agaiu^ Ilcrr Bickhardt and I may 

 each retain our own. 



In the Berlin Catalogue Xenonychus, WoU., is set aside 

 for Styphi'us, which, I think, has no status at all ; but Mero- 

 hister, Reitter, is admitted as a " subgenus,^' although tlie 

 name of Pacfolinus has a similar relation to it that Sli/phncs 

 Las to Xenoni/c/nis. 



Bickhardt also considers Saprinus immundus, Gyl.=: 

 eeneus, F. ; Reitter in the ' Fauna Germanica,' 1910, correctly 

 separates them. 



Pachylomalus leo, Mars. 



The type of this species is in the Genoa Museum and is 

 apparently a male, because JNIarseul tells us that the first 

 segment of the abdomen is elevated in the middle of the 

 posterior border, and this is a masculine character. Had he 

 been describing the male of tuberosus, Lew., he could not 

 have overlooked the conspicuous tubercles on the pro- 

 pygidium ; he simply says that it is smooth and a little 

 convex. P. tuberosus in the Berlin Catalogue stands as a 

 synonym of victor, Mars., a species which is smaller and has 

 no marginal stria on the mesosternura. The three species 

 named come from Java, Sumatra, aud Borneo respectively. 

 I have also a species very similar in size to tuberosus from 

 Sumatra, in which the prostcrnal strice distinctly meet at 

 both ends and there are no lateral strise on the mesosternum ; 

 the specimen is a female. 



Paromalus Javanus, Redtenbacher, Reis. Novar., 

 Zool. p. 33 (1867) 



" Oblongo-ovatus, subconvexus, subtilissime vage punctulatus, niger, 

 nitidus ; antennis ferrugineis ; thorace stria margiuali antica 

 Integra ; elytris striis nullis ; prosterno bistriato ; mesosterno stria 

 bisinuata. 



" Long. 2'", latit. 4i"'." 



The species is said to be larger and shorter than P. com- 

 planatus, Panz., and I think that it is a Paromalus. 

 Dr. Redteubacher's measurements ai'e incorrect, and my 

 reading of the diagnosis is that the mesosternal stria is 

 complete (being described as bisiuuous), and the species 

 cannot therefore be referred to Paromalus schultheissi, Sch., 

 a very common Javan species^ and which has the mesosternal 

 stria widely interrupted.
