of abdominal paratergites (margining). This character will dis- 
tinguish them at once from all other Staphylinidae (except possibly 
some of the highly specialized inquilines). The only character found 
that will distinguish the Osoriini from the other four groups is the 
presence of a transverse sulcus on the anteria coxa. It is therefore 
concluded that these groups must all be placed in one subfamily, 
which will properly be called the Osoriinae. This group has nothing 
to do with the Oxytelinae, and while at present it must be placed after 
that subfamily, future rearrangements in the family are certain to 
separate them widely. 
If this character of the coxal sulcus be used as the primary basis for 
dividing the subfamily, one gets two groups, the Osoriini and the 
remainder, the latter being separable on the closure of the coxal 
cavities into Leptochirini and Lispinini. These three tribes will then 
comprise the subfamily Osortinae.

In the Lispinini there are two groups of genera that have been 
rather heterogeneous. In each group there were some genera having 
the anterior coxae separated by a spatulate process of the prosternum 
and some not. It seems certain that we are here dealing with a group 
in which similar appearance has arisen in several stocks. This paral- 
lelism is very confusing if only specifie characters or general facies are 
observed. However, the lumping of all these genera and then their 
initial segregation on the character of the separation of the anterior 
coxae gives us two groups that while somewhat heterogeneous in 
appearance are much more homogeneous structurally than those 
obtained by the previous method. This division of the groups seems 
to be an important one, and the character is more usable than that of 
the shape and size of the coxae, with which it is correlated. The use 
of this character of the separation of the coxae, along with the others, 
enables us to divide the tribe into five subtribes.
