narrowed slightly at the meson, but its occipital margin distinctly 
concaVe; ocelli in a triangle in the center of the vertex, nearer to the 
cephalic margin of the latter than to its occipital margin and the 
group distance from the eyes. The occipital foraminal depression 
marked, concave, its margins rounded or obtuse, immargined. 
Antennae 13-jointed, with two distinct ring-joints and a 3-jointed club, 
the flagellum usually moderately clavate (lateral aspect), the club 
conical and wider than the funicle but not abrupt or spherical and 
the funicle cylindrical, very gradually enlarging distad; p'edicel 
obconic, smaller than the first funicle joint or subequal to it, the six 
funicle joints all subequal and subquadrate. (Fig. 1). 
Pronotum visible, widened or dilated laterad, narrow at the 
meson, at that point but a sixth the length of the mesoscutum, 
subobtuse; parapsidal furrows not conspicuous but distinct, shallow, 
incomplete, extending caudo-mesad from the c'ephalic margin of the 
scutum to about two-thirds their length; cephalic and caudal margins 
of the mesoscutum gently convexed; axillae widely separated *, 
scutellum nearly as in Habrocytus thyridopterygis Ashmead, normal, 
with a rather obscure transverse groove just before (cephalad) of its 
apex, best seen from the caudo-lateral aspect in shadow and appearing
