arbitrary divisions, depending on the peculiar ideas of indi- 

 vidual authors," So here, again, Ilerr Bickhardt and I may 

 each retain our own. 



In the Berlin Catalogue XenonycJms, Woll., is set aside 

 for Styphrus, which, I think, has no status at all ; hut Mero- 

 histei', Reitter, is admitted as a " subgenus/' although the 

 name of Padolinus has a similar relation to it that Styphrus 

 has to Xenonychus. 



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 Marseul 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 mesosternum. The three species 

 named come from Java, Sumatra, and Borneo respectively. 

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

 Sumatra, in wiiich the prosternal striae distinctly meet at 

 both ends and there are no lateral striae 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 ; antennia ferrugineis ; thorace stria marginali antics 

 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. Redtenbacher's measurements are incorrect, and my 

 reading of the diagnosis is that the mesosternal stria is 

 complete (being described as bisinuous), and the species 

 cannot therefore be referred to Paromalus schultheissi, Sch,, 

 a very common Javan species, and which has the mesosternal 

 stria widely interrupted.
