STUDIES IN NEOTROPICAL MALLOPHAGA—CARRIKER 87 
encircling the frons, internal clypeal bands running from base of an- 
tennal bands to front of head; occipital bands continuous from base of 
antennal bands to sides of occiput. 
Thorax small, the combined segments much smaller than the head. 
Prothorax quadrilateral; pterothorax with mesothorax indicated, 
but the two segments completely fused; sides slightly divergent and 
posterior margin flatly convex, with numerous, very long, pustulated 
hairs set submarginally. 
Abdomen elongated, widest at segments V and VI, similarly shaped 
in the two sexes, and composed of nine segments, with segment IX 
very small; tergal plates widely separated medially; paratergal plates 
very narrow and fused to tergites; sternal plates apparently absent. 
Male genitalia well developed, basal plate longer than paramers; 
paramers heavy; dorsal endomeral plate large, with small penis 
attached; slender ventral endomeral plates on each side of base of 
dorsal sclerite. Legs stout but not excessively long, with tibiae and 
femora about equal; trochanters well developed; the second and 
third pairs of coxae unusually large, articulated near sides of thorax, 
and with more than half of segment outside of body. 
The genus superficially resembles some of the circumfasciate forms 
of Degeeriella, but the head structure seems to be unique, while the 
genital armature is of an entirely different type, as well as the struc- 
ture of the abdominal sclerites. It probably bears a relationship to the 
Degeeriella group similar to that which Pseudophilopterus bears to 
Philopterus and Pseudolipeurus to E'sthiopterum. 
This is the third known genus of Philopteridae whose true host is un- 
questionably a species of Tinamidae. It has been clearly proved that 
the true host of Lipeurus rhynchoti Carriker is a species of Cracidae 
and that Cuclotogaster laticorpus Carriker is the ordinary chicken 
louse, Cuclotogaster heterographus (Giebel).1. I doubt very much 
whether the true host of L’'sthiopterum tatauwpa Carriker is Crypturellus 
tataupa, and so the only Philopteridae left whose true hosts are un- 
questionably species of the Tinamidae are Pseudolipeurus, Pseudophil- 
opterus, and Tinamotaecola.
