MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 57 



Records. — The following are the records known to me: 



Hispaniola: Haiti, Mnrne La Selle (Rlackwelder station 22C), La Visits (Dar- 

 lington, in M.C.Z. and U.S.N.M.) ; Dominican Republic, Loma Kucilla 

 (Darlington, in M.C.Z. ). 



Specimens examined. — I have seen only the three types and three 

 specimens from the Museum of Comparative Zoology. 



Remarks. — This species seems to be quite distinct from the described 

 American ones. It was found at a high elevation (for the West 

 Indies), similarly to the Central American species recorded by Sharp. 



The specimens were taken by beating plants along the edge of the 

 jungle, where it was replaced hj pine forest. 



Subfamily Oxytelinae 



This name has been used for groups of various ranks in recent 

 years, but in the Junk Catalog ' it is treated as a subfamily, which 

 includes the Piestinae, the Omaliinae, the true Oxytelinae, and the 

 Osoriinae. In this condition it is exceedingly difficult to define the 

 subfamily or to arrange characters so that it may be placed in a key. 

 The Osoriinae, the Omaliinae, and the true Oxytelinae may each be 

 defined readily by a single morphological character of considerable 

 importance, and there seems to be no reason whatsoever for grouping 

 them under one head. Indeed, recent studies indicate that these 

 four groups are not at all closely related, and each of them is there- 

 fore treated here as a subfamily. 



The Oxytelinae may be recognized among all staphylinids by the 

 presence of a complete sclerite in the second ventral abdominal seg- 

 ment. This gives them an additional "visible ventral segment." 



Eight genera have been recorded from the West Indies.
