General Introduction. 
Since Professor Kellogg has published a list of Mallophaga, in 
Wytsman’s Cenera Insedorum, so recently as 1908, my reasons for 
preparing the present publication require an explanation. This explana¬ 
tion involves some criticism of Kellogg’s list, but my main reasons are 
concerned rather with the plan of this list than with the few errors and 
omissions that I indicate. 
In the first place, Kellogg’s work includes only what, until the 
contrary is proved, may be presumed to be valid species. No synonyms 
are included, and as these synonyms are very numerous, it has appeared 
to me useful to bring them all together. When such an- astute worker 
as Piaget has been led more than once to use anew a name that had 
fallen into oblivion as a synonym, the risk of more recent workers 
doing the same thing need hardly be emphasised.
