Group Aleocharina.

Mr. Lewis has brought from Hakodate a single specimen, 

 having the elytra of a clear pale red colour. 1 do not know 

 whether it is distinct or only a variety of A. claviger. It 

 conies very near to A. celebetisis, Fauv., but is more finely 

 punctate. 



Aleochara discoidea. 



Aleochara discoidea, Sharp, Tr. Eat. Soc. Lond. 1874, p. 7. 



A small series of examples from different localities on the 

 main island show that this is either a very variable species or 

 tliat there may be two or three species in Japan very closely 

 allied to A.fascipes^ L. ; but the material is quite insufficient 

 to form a judgment on. 



Aleochara lata? 



Aleochara lata, Gravenhorst, Col. Micr. p. 186. 



Kiga and Miyanoshita ; two specimens. These examples 

 do not agree exactly with either European or North- American 

 specimens, and may possibly be distinct ; they are very broad 

 and densely punctate. 



Aleochara asiatica. 



Aleochara asiatica, Kr., Wiegm. Arch. f. Nat. xxv. p. 13 (sep. pag.). 

 Aleochara japonica, Sharp, Tr. Eut. Soc. Lond. 1874, p. 8. 



We have not yet obtained in Japan any examples with 

 red elytra, such being, according to Kraatz, the ordinary form 

 in Ceylon ; but botii Kraatz and myself have pointed out that 

 the species is variable in colour, and I have no doubt that the 

 two forms are not distinct. 



Aleochara niponensis, n. sp. 



Nigra, fusco-pubescens, antennarum basi pedibusque testaceis ; dense 

 punctata ; antennia apicem versua latioribus, articulis 5"-10"' traus- 

 verais.
