STUDIES IN NEOTROPICAL MALLOPHAGA (III) 
[TINAMIDAE No. 2] 
By M. A. Carrixer, Jr. 
Since the publication in 1936 of my first report on the Mallophaga 
of the tinamous, I have acquired much additional material of this 1n- 
teresting group, not only of the same species treated in that report 
but also of many additional ones, some from the same hosts and others 
from hosts on which no Mallaphaga had previously been recorded. 
Several other workers on Mallophaga have, in the meantime, described 
additional species and reexamined old types, with the result that much 
further light has been shed on little-known genera and species, mak- 
ing it necessary now to revise many of the conclusions reached in my 
first report. 
For the present paper I have very carefully worked over all my old 
material in connection with the new, taking into consideration the 
critical notes published by other authors, many of which I heartily 
endorse while with others I am forced to disagree. These matters 
will be fully considered under the pertinent genera and species. 
The large quantity of material I have assembled and studied has 
enabled me to arrive at some tentative conclusions that I am convinced 
further work will corroborate. Miss Clay (1937) has suggested that 
some of the genera erected by me in 1986 may prove to be unnecessary 
and that additional species may be found which will form connecting 
links between certain genera. However, I am not prepared to take 
this view. On the contrary, the more I study this fascinating family 
of Mallophaga the more I am convinced that we are dealing with a 
large number of genera composed of species and subspecies very closely
