Psyche 
[December 
with a transverse oval scar-like area, slightly elevated from the rest 
of the surface. This scar-like area has the surface roughened and 
with some very short erect hairs. Segment III l/ 2 times as long as 
I, almost circular in cross-section and slightly curved posteriorly; 
IV as long as I, almost tubular ; rest decreasing gradually in thick- 
ness and almost imperceptibly in length; XI 2/8 as wide as III, 
l/3 longer than X. 9 antennae 2 3/5 as long as an anterior tibia; 
segment I reaching to just beyond the margin of the eye, the rest 
bearing approximately the same proportion to I as in the $ but 
more slender basally and not tapering as much, so that XI is only 
3/4 as wide as III. 
Pronotum quadrate, l/lO broader than long. Sides straight, 
diverging slightly from base to l/3 from apex, then forming a 
fairly sharp angle, converging abruptly to the collar, which projects 
forward slightly. Surface densely punctured and microreticulate. 
Disc elevated in the center into a low hump; from the central hump 
a set of more or less well-defined ridges project as follows: an- 
teriorly a strongly elevated ridge, sometimes higher than the hump 
near its base ; laterally a weak pair tending anteriorly and ending 
in a pair of feeble elevations on the edges of the disc; posteriorly 
a weak pair directed toward the posterior angles, leaving the mid- 
dle of the base more or less excavated. Pubescence of disc confused, 
directed generally away from the central hump, toward the lateral 
elevations and often in a pair of whorls anteriorly. 
Elytra with black scutellar markings extending across the base 
and forming a very weak humeral spot of a few hairs. Suture 
elevated on the basal l/4 and apical l/3. Underside with antero- 
lateral black spots on sternites II to IV, sometimes also on I and V, 
posterior midventral spots on II to IV, often on V in the $ , re- 
duced to one spot, on III, in one 9 . Middle and posterior trochan- 
ters and femora of $ denuded behind, the denuded area having 
scattered short black hairs and margined above with long cinereous 
hairs ; the femora slightly bowed, the middle femora more than the 
posterior. Posterior tibia! spurs slender, sticklike.
