Psyche 
[March 
border slightly and evenly rounded, scarcely projecting in 
the middle; its lateral portions not reaching the anterior 
corners of the head, convex but not auriculate. Frontal area 
distinct, moderately large and triangular; only a portion of 
the frontal groove developed in the middle of the head just 
anterior to the ocelli ; frontal carinse widely separated, sub- 
parallel, rather erect and slightly lobular anteriorly, con- 
tinued back to the anterior orbits of the eyes. Antennae 
8-jointed; scapes curved basally, gradually thickened dis- 
tally, their tips reaching somewhat beyond the middle of 
the eyes; funiculi distinctly enlarged apically, first joint 
twice as long as broad; second and third 11/2 times as 
long as broad, remaining joints nearly as broad as long, 
except the terminal joint which is somewhat longer. Thorax 
stout anteriorly, the pro- and mesonotum convex, forming 
together a hemispherical mass, separated by a distinctly 
impressed suture, rounded above in profile, the former as 
broad as long with a faint median longitudinal impression 
behind ; the latter as long as broad, subcircular with straight 
posterior and rather deeply impressed anterior and lateral 
sutures. Behind the mesonotum the thorax is divided into 
two regions by a transverse dorsal furrow ; the shorter ante- 
rior portion, representing the metanotum is depressed and 
bears the somewhat projecting metanotal spiracles at its 
sides; the posterior portion, representing the epinotum, is 
as broad as long, with the base somewhat convex and bear- 
ing the epinotal spiracles at the middle of its sides. Pos- 
teriorly it passes into the distinctly shorter, sloping de- 
clivity, with which it forms a distinct, obtuse angle. Petiole 
small; its node from above transversely elliptical, nearly 
1 2/3 times as broad as long; in profile distinctly cuneate, 
with convex anterior and posterior surfaces, the moderately 
sharp superior border transverse, feebly and broadly ex- 
cised or sinuate in the middle. Gaster large, elongate-ellip- 
tical. Legs stout ; all the femora somewhat thickened ; spurs 
of middle and hind tibiae very short; tarsal claws large and 
stout. 
Smooth and shining; mandibles coarsely punctate, with 
a few incomplete longitudinal rugules; head more finely 
punctate ; median portion of clypeus, front and cheeks 
finely and longitudinally striate as far back as the eyes.
