cipital margin of vertex far from the eyes, with a distinct 
inward curve, margined by a blunt carina which does not 
continue on the cheeks. Cheeks narrow, though distinct, 
about one-fourth the width of the eye in profile, gradually 
narrowed toward the vertex and evenly rounded in the lower 
half. Oculo-malar space short, but distinct, a little over 
one-fourth as long as the width of the mandibular articula- 
tion. Eyes more bulging than usual in the subgenus Pseu- 
domasaris, proper. Inner orbits more than three times as 
far apart at the clypeus as on the vertex, where the eyes are 
separated by about three times the diameter of a posterior 
ocellus. Frons flat, not carinate, very faintly raised between 
the insertions of the antennae, with the merest trace of a 
median tubercle in the center, shallowly concave below the 
anterior ocellus. Ocular sinus deep, bluntly rounded at apex 
Ocelli large, in a flattened triangle; the anterior ocellus 
much larger than the others, subcircular; posterior ocelli 
about twice as far apart as their diameter, barely separated 
from the inner orbits, distant from an imaginary line con- 
necting the posterior borders of the eyes by a little over 
twice their distance from each other. Interocellar area flat. 
Vertex strongly sloping posteriorly, slightly concave in 
front view. Antennae about four times as far apart as they 
are removed from the inner orbits. Clypeus strongly and 
evenly convex throughout, in outline flattened hexagonal 
with rounded upper angles, nearly one and one-half times as 
wide as long; the anterior, free portion about one-fourth 
shorter than the basal, interocular part; the upper margin 
slightly convex; the upper lateral margins slightly oblique, 
very broadly separated from the eyes, the intervening space 
wider than the length of the oculo-malar space; the lower 
lateral margins slightly concave, .forming almost right 
angles with the upper lateral margins; the truncate apex 
a little over half the maximum width of the clypeus, deeply, 
arcuately emarginate ; the apical angles very broadly 
rounded, with a translucent border. Antenna of 12 seg- 
ments, very long, shaped much as in P. occidentals, but the 
third to seventh segments more slender than in that species ; 
the third to sixth not at all enlarged at their apices; the 
seventh slightly and evenly widened toward the apex, where
