STUDIES IN NEOTROPICAL MALLOPHAGA—CARRIKER 177 
I have two males with the genital armature half extruded, both in 
splendid condition for study. In the drawing published by Miss 
Clay the paramers are shown as jointed to the basal plate. This is an 
error, as can be plainly seen in my material, since they are completely 
fused with the basal plate, the only evidence of point of fusion being 
the thickening of the margins in the paramers. Her figure of the en- 
domeral sac is also somewhat misleading, since it is distorted, being 
pulled to the left. In my materia] there are two males that show 
this distortion, the remaining being normal, as in the figure herewith 
presented. 
Genus HEPTARTHROGASTER Carriker

Goniodes minutus CARRIKER, Univ. Nebraska Stud., vol. 8, No. 2, p. 155, pl. 4, 
figs. 1, 2, 1908. (Host: Tinamus robustus=T. major castaneiceps.) 
Heptarihrogaster minutus (Carriker) CARRIKER, Lice of the tinamous, p. 135, 
pl. 20, figs. 2-2b, 19386. (Host: Tinamus major castaneiceps.) 
This genus seems to be rare. Since the publication of the “Lice 
of the Tinamous,” 1936, I have been able to secure the following addi- 
tional material of this species: Two females from Tinamus s. serratus, 
Bolivia; one male and two females from 7’. serratus ruficeps, Colom- 
bia; one male from Crypturellus garleppi affinis, Bolivia (which may 
possibly belong to 7. s. serratus), and a series of 24 males and fe- 
males from Tinamus major percautus, Mexico. There are certain 
roinute differences between the specimens from 7. s. serratus, T. s. 
rujiceps, and 7. major castaneiceps (the type series), but these are so 
small that it does not seem advisable to separate them, especially in 
view of the small amount of material available for study. However, 
the series from 7. major percautus seems worthy of subspecific rank 
and is described below.

Types—Male and female, adults, from Tinamus major percautus, 
collected by the author at Cerro Tuxtla, Veracruz, Mexico, March 23, 
1940; in the U. S. National Museum. 
This race agrees rather closely with H. m. minutus in many respects. 
There is a noticeable difference in the shape of the head in the male, 
as well as in the shape and proportions of the genital armature. 
They are also slightly larger in all respects, and so it seems advisable 
to recognize this form.
