[June 
Female. — Measurements (Table I). 
Morphology. — Subgenital plate (fig. 76) with posterior margin 
rounded ; T-shaped sclerite with arms broad and diffuse. Ovipositor 
valvulae (fig. 77) : third valvula with notch near apex marking 
presence of secondary lobe. Spermatheca (fig. 78) : sac of two dis- 
tinct regions separated by a constriction, the part proximal to the 
duct a narrow, tapering, curved neck. Paraproctal sensorium with 
8 setae, none with true basal rosettes. 
Color (in alcohol). — Head same as in male except frons grayish 
white with two pale grayish brown spots below ocelli. Thorax same 
as in male except for presence of a red band running length of thorax 
on dorsal midline. Abdomen same as in male except that dark brown 
dorsal spot at base much larger, covering all of first two terga. 
Type locality. — Upland rain forest 8 miles northwest of Santiago 
Tuxtla, Veracruz, Mexico (Sierra de las Tuxtlas), June 24, 1966, 
E. L. Mockford collector. Holotype S , allotype 9 , 2 cf paratypes, 
and 1 nymph. Types are in the author’s collection. 
Habitat. — These insects were found on the trunk of a large tree 
with buttressed base deep in the upland rain forest. On the same 
trunk in the immediate vicinity of these specimens were several species 
of Ptiloneurid psocids. 
Discussion. — A single female, probably representing a distinct 
species of this genus, was taken at Chorroni, Aragua State, Venezuela, 
in the coastal mountains. Like the Mexican female, it is micropterous. 
Family Compsocidae, new family 
Diagnosis. — Antennae of 13 or 14 segments. Frontal sutures 
present. Lacinial tip with lateral cusp curved outward and bearing 
a few indistinct, rounded denticles. Row of denticles present on 
anterior carina of first femur. Tarsi three-segmented. Pretarsal 
claws each with two preapical denticles. Mesothoracic tergal lobes 
not protruding above a line drawn from vertex of head to dorsal
