others and I have not attempted to resurrect them at the present 
time, as like those of Lioy they give endless opportunity for 
opinionative discussion and disagreement. At most, but few 
changes in generic names could result, to whatever species these 
names should be attached. 
The change of Trineura to Phora, which has been adopted by 
others appears in the following pages. It is an unfortunate 
change, but there can be no question of its propriety on nomen- 
clatory grounds, as was pointed out years ago by the present 
writer. 
Most of the genera listed seem to be fairly pure, with perhaps 
the exception of Puliciphora and Dohrniphora. The former is 
known mainly in the wingless female sex and from its cosmopoli- 
tan distribution is no doubt of polyphyletic origin. Dohrniphora 
includes a number of more or less heterogeneous types and is 
undoubtedly an artificial group which will probably later have 
to be subdivided in part and also partially merged with other 
genera. It was originally based on a rather peculiar species which 
has a number of close relatives, but now includes a majority of 
the species of the old genus ‘Thora” and some of the species re- 
ferred to it in the following pages can be easily placed in doubt- 
ful cases only by the elimination of other related genera. 
A number of very highly modified apterous types some of which 
are myrmecophilous or termitophilous are referred to a series of 
monotypical or very small genera. Many of these are known only 
as females and the discovery of winged males will probably show 
that the number of genera now recognized must be much reduced. 
The geographical distribution of all of the larger genera is 
very extensive, remarkably so, considering the highly modified 
character of the family, and until more is known of the faunae of 
other regions beside Europe and North America no' generaliza- 
tions of importance can be made. A few common species have 
undoubtedly been widely disseminated through human agency. 
The habits of the Phoridae are extremely varied, but the cita- 
tions in the present catalogue have been restricted almost en- 
tirely to taxonomic references as the ethological data would have 
considerably increased its size. These have been recently sum- 
marized in a very brief way by Malloch^ to whose paper the reader
