STUDIES IN NEOTROPICAL MALLOPHAGA—CARRIKER Ol 
temples wider in the female than in the male, precisely as in the speci- 
mens from C. 0. punensis. | 
The parasites from C. b. boucardi are therefore entitled to subspecific 
rank, and the single male taken on C.. cinnamomeus sallaei must go 
along with them, since practically all of its body measurements are 
within the extremes given for the material from boucardi, while the 
genital armature is even closer. 
Had there been the slightest possibility of straggling, I would say 
that C. cinnamomeus sallaet is not the true host of this single male, 
but since the specimen of C’. ¢. sallaei was shot prior to the taking of 
any birds of C. b. boucardi, all thought of straggling is eliminated. 
The single male taken on Tinamus major percautus also obviously be- 
longs to that host and is very close to the specimens from C. 6b. bou- 
cardi, especially in its body measurements, all of them except two fall- 
ing within the extremes for the boucardi material. However, the 
genital armature is not the same, and this, after all, is the safest char- 
acter to use inthis group. In addition, the shape of the last abdominal 
segments differs, and so it seems advisable to give this specimen sub- 
specific rank. 
We therefore have the following arrangement of the races of P. 
longipes and their respective hosts: 
PSEUDOLIPEURUS LONGIPES LONGIPES (Piaget) 
Lipeurus longipes PiaceT, Les Pédiculines, p. 329, pl. 28, fig. 3, 1880. (Host: 
Tinamus obsoletus=Crypturellus o. obsoletus, Brazil.) 
PSEUDOLIPEURUS LONGIPES SIMILIS, new subspecies 
FIGURE 2, b 
Types.—Male and female, adults, from Crypturellus b. boucardi, 
collected by the author on Cerro Tuxtla, Veracruz, Mexico, March 28, 
1940; in U. S. National Museum. 
Differs from P. 1. longipes and P. 1. carrikeri in much smaller size 
and in size and proportion of the male genitalia and also from P. 0. 
longipes in sexual dimorphism (see previous discussion). 
A single male of this race was also taken on Crypturellus cinna- 
momeus sallaez, shot at Tres Zapotes, Veracruz, Mexico, on March 27, 
1940. 
PSEUDOLIPEURUS LONGIPES ROBUSTUS, new subspecies 
FIGURE 2, @ 
Type.—Male, adult, the only specimen, taken on 7inamus major 
percautus, collected on Cerro Tuxtla, Veracruz, Mexico, by the author 
on March 23, 1940; in U. S. National Museum.
