NEW SPECIES AND RECORDS OF STAPHYLINID BEETLES 

 FROM FORMOSA, JAPAN, AND SOUTH CHINA 



By ISIalcolm Cameron 



A COLLECTION of 950 Specimens of beetles belonging to the family 

 Staphylinidae from Hainan Island, southeast China, Formosa, the 

 Loochoo Islands, and Japan has been turned over to me for report 

 by Dr. R. E. Blackwelder, of the United States National Museum. 

 These specimens were collected during several trips from 1932 to 1935 

 by Dr. J. Linsley Gressitt, now of Lingnan University. 



Two new genera, 22 new species, 1 new variety, and many new records 

 are included. Unless otherwise noted all specimens were collected by 

 Dr. Gressitt. Holotypes are in the United States National Museum 

 except as noted ; paratypes of all new species are in my collection ; and 

 paratypes of most of the new species are also in the Gressitt Collection 

 in the California Academy of Sciences. Dates are abbreviated, as, for 

 example, V-7-32=May 7, 1932.
