STUDIES IN NEOTROPICAL MALLOPHAGA—CARRIKER 135 
lected by the author in the Sierra Perij4 of Colombia, which agree in 
every way with the type material. 
Five females taken on 7inamus s. serratus, collected by the author at 
Todos Santos, Rio Chaparé, Bolivia, agree so closely with the female 
type of genitalis that they must be classed with that species. 
RHOPALOCERAS BREVITEMPORALIS Carriker 
Rhopaloceras brevitemporalis CARRIKER, Lice of the tinamous, p. 112, pl. 18, figs. 
1-le, 1936. (Host: Crypturellus obsoletus punensis.) 
An additional series of this species was taken on Crypturellus obso- 
letus crucis by the author at Samaipata, Bolivia, November 2, 1937. 
These specimens apparently agree in all particulars with the type series 
from C’. 0. punensis. It would seem, from a study of the mallophagan 
parasites taken on C’. 0. crucis, that this new race of tinamou is a rather 
poor one, especially since it was based on a single specimen, probably 
nothing more than a very old, richly colored male bird. 
RHOPALOCERAS RUDIMENTARIUS Carriker 
Rhopaloceras rudimentarius CARRIKER, Lice of the tinamous, p. 113, pl. 14, figs. 
1—1e, 1986. (Host: Crypturellus soui nigriceps.) 
A series of 11 males and females from three individuals of Cryptu- 
rellus soui meserythrus collected by the author at Tres Zapotes and 
Cerro Tuxtla, Veracruz, Mexico, between February and May 1940, 
agree with the type series of rudimentarius in every particular. The 
male and female genitalia and the number of teeth in the combs of the 
various abdominal segments are identical. 
Three males and three females were also taken on Orypturellus soua 
(mustelinus %), collected by the author at Airoca, Sierra Perij4, Col- 
ombia, April 7, 1942, which cannot be separated from the typical speci- 
mens. ‘This makes the seventh race of Crypturellus soui on which this 
species of Rhopaloceras has been taken by the author, in addition to 
two races of C. undulatus. 
The Mexican series is, perhaps, more nearly identical with the types 
than some of the others, but they all run exceedingly close. In such 
a widespread genus as Fey eatoeen oe: containing so many species, it 
is very significant that the various races of Crypturellus sowi are ex- 
ceeding close in their relationships. This same fact was noted under 
Strongylocotes subconiceps.

An additional pair was taken on the type host, collected by the 
author at Rio Lipeo, southern Bolivia, and another pair on the same
