Psyche 
[September 
as in Meranoplus. Eyes set obliquely, slightly in front of 
the middle of the head, moderately large and convex, but 
consisting of comparatively few hemispherical facets (only 
4 or 5 in the greatest transverse diameter) , elongate- 
elliptical, produced inferoanteriorly as a distinct point. 
Ocelli absent. Mandibles rather small, with short, oblique, 
4-toothed apical borders. Clypeus short, its posterior por- 
tion forming an elevated, laterally marginate plate, termi- 
nating on each side anteriorly in a small, sharp tooth and 
extending back between the frontal carinse. In profile the 
outline between the anterior edge of the median plate and 
the anterior border of the clypeus is strongly concave. 
Frontal carinse widely separated, subangulate, laterally ex- 
panded and lamellate anteriorly but not reaching the sides 
of the head and hence more as in Triglyphothrix than in 
Meranoplus, continued backward as two sharply, only mod- 
erately divergent ridges which form the mesial borders of 
broad, deep, supraocular scrobes that are rounded pos- 
teriorly and each large enough to contain the whole folded 
antenna. Frontal area distinct, frontal groove obsolete. 
Antennae 10-jointed; scape short, first funicular joint con- 
spicuously enlarged, joints 2-7 short and transverse, the 
seventh longer than the others which are small and nar- 
row, the two terminal joints forming a large club, the last 
joint of which is much larger than the penultimate, as long 
as the remainder of the funiculus without the first joint. 
When the antenna is folded into the scrobe, the club is 
turned mesially so that it overlies and conceals nearly the 
whole scape and fits into the space between the plate and 
depressed lateral portion of the clypeus. Thorax short 
and stout, the pronotum large, moderately convex, with 
sharply rectangular humeri and submarginate sides ; prome- 
sonotal and mesoepinotal sutures obsolete, the latter re- 
placed by a dorsally transverse, longitudinally costate 
groove; epinotum short and narrow, sloping, armed with 
a pair of teeth or spines which are placed low down; 
metasternal angles distinct but rounded. Petiole and post- 
petiole with well-developed but not enlarged nodes, the 
petiole subpedunculate anteriorly, with an anteroventral 
tooth. Gaster much as in Meranoplus, oval, with about
