Psyche 
[March-June 
the bases of the mandibles appear like the crown of a molar; 
the right mandible in repose (clinched) is uppermost and 
slightly shorter than the left. Antennae: scape club-shaped, 
slightly bent, longer than the funicle and clava combined, black, 
glabrous, with a few setae at the elbow, and when folded back- 
ward, extending to the acuminate post-ocular process; funicle 
one fifth longer than the clava, first segment subglobose (pear- 
shaped), slightly longer than the second; second, third and 
fourth of equal length, subcylindrical, anterad dilated, fifth 
nearly pentagonal in outline and distinctly longer than the 
fourth, with a single seta on the apex, sixth as long as the fifth, 
produced into an elongate acute point, on which occurs a clump 
of setae; clava compact, three-jointed, rufescent, eighth seg- 
ment anterad produced in a lobe with a truncate apex, base 
glabrous, black, lobe spongy, ninth segment spongy throughout, 
lobe pointed, tenth segment rounded, spongy, embellished with 
a central circular litura; lobes of clava distinctly flattened. 
Prothorax broadly convex, nearly twice as broad as long, granu- 
late punctate, opaque, disc with a few scattered punctures, 
feebly shining; anterior and lateral areas shallowly pitted with 
roundish, large pits, gradually diminishing in size and intensity 
toward the posterior angle; anterad bisinuate, antero-lateral 
angles obtusely pointed, broadly rounded from anterior third 
to posterior angles, latter produced into an obtuse point, thence 
diagonally truncate to base, which is broadly rounded; margins 
reflexed, laterad and basad delineated by an impressed line. 
Scutellum as long as broad, heart-shaped, with several irregu- 
lar punctures, shining. Elytra narrower than the prothorax, 
broader, however, than the prothoracic base, one and one-half 
times as long as broad, broadest one quarter the length from 
humeri, parallel to the middle, thence gradually and gently 
rounding to apex; humeri angulate and rounded on top; each 
elytron with a single stria, beginning in the ante-humeral region 
(one-third the elytral width) and attaining to four-fifths the 
elytral length; margins reflexed from the broadest point to 
apex; dark chocolate-brown, densely punctured, opaque; su- 
ture narrowly impunctate, shining. Legs fairly stout, black, 
linearly sculptured; anterior tibiae distad broadly bilobed, 
armed externally with four large teeth, second largest, serrate 
between; intermediate tibiae with a single central spine, pos- 
terior with a denticle; tarsi as long as the tibiae, glabrous, each
