STUDIES IN NEOTROPICAL MALLOPHAGA—CARRIKER 101 
The male genital armature is, however, the most striking of the 
distinctive characters of the species. The basal plate is nearest to 
that of longipes, yet not the same, while the massive paramers are 
more or less of the same type as in grandis, sanctae-martae, and 
subsimilis, but the endomeral plate is unique for this genus in the 
structure of its posterior portion. The pair of “claspers” found in 
grandis and longipes is entirely absent, as well as the bifurcated penis 
of longipes and sanctae-martae, that organ being furnished with a 
row of spines near the tip.

PSEUDOLIPEURUS GRANDIS Carriker 
FIGURE 4, a—c 
Pseudolipeurus grandis CARRIKER, Lice of the tinamous, p. 73, pl. 3, figs. 1, 1a, 
19386. (Host: Nothocercus nigrocapillus.) 
This species was described from a single female taken on J. n. 
nigrocapillus from Sandillani, Bolivia. In 1941 five females and a 
male of this species were taken from Nothocercus bonaparti, in the 
Sierra Perijé of Colombia. The five females are almost identical with 
the type of grandis, there being but insignificant differences in measure- 
ments, and so until the male can be examined from the type host 
(V. nigrocapillus) I prefer to use the name P. grandis for these spec- 
imens from J. bonaparti. 
Should the male from JN. n. nigrocapillus prove to be different from 
the male here figured (from WV. bonaparti), then the specimens from 
the latter host will have to be named, but I doubt very much whether 
they will prove to be even subspecifically different. 
Diagnosis of male.—In this species there is an unusual discrepancy 
in size between the sexes, not only in the length and width of the 
abdomen but also in all the body segments. The cephalic index in the 
female is slightly less than in the male, the temples being wider. There
