Psyche 
[March 
maxillary palps. Dorsal surface of head, pronotum, and elytra 
virtually glabrous except for elytral macrosetae. Length: 2.6 mm; 
width: 1.2 ± 0.03 mm (only two specimens seen). 
Head capsule similar to that of pustuliferum (fig. 58), but eyes 
more prominent and epistomal suture lacking median stem. An- 
tennal length about 1.3 times head width, first seven antennal 
segments without dense pubescence, antennal club three-segmented, 
apical segment four times as long as preceding segment (see fig. 52). 
Ocellar diameter about 0.08 times head width. Labrum approxi- 
mately rectangular (anterior margin straight). Maxillary palp with 
fourth segment about 4.5 times as long as third, the two subequal in 
width. 
Pronotum as in fig. 2, with shallow median and lateral depres- 
sions, lateral margins explanate. Prosternum coarsely punctate with 
median longitudinal carina. Mesosternum with dense microsculp- 
ture except on mesosternal process, cavities for reception of pro- 
coxae about half the length of the mesosternum, mesosternal 
process similar to that of pustuliferum (cf. figs. 34, 36), extending 
about two-thirds of the way between mesocoxae. Metathorax 
convex, without microsculpture, coarsely punctate with minute 
setae in punctures; antecoxal sutures short, extending one-fifth to 
one-fourth the width of the metasternum. Male protibia with a few 
external spines near apex, meso- and metatibia with a few more 
spines, female tibiae with fewer spines than male. Hind tarsus about 
two-thirds as long as hind tibia, fifth segment of hind tarsus three- 
fifths as long as first four segments together. Empodial setae 
subequal in length to tarsal claws. 
Elytral striae impressed between punctures, elytral intervals finely 
sparsely punctate between macrosetae on alternate intervals. Elytra 
without pale spots or raised pustules. Angle formed by elytral apices 
at suture slightly greater than 180° (concave posteriorly). Wings 
fully developed. 
Abdomen with tergites 5 to 8 well-sclerotized, spiracles located in 
tergites of these segments (possibly 4 also); sutures between sternite 
and paratergites apparently lacking on segments 3 to 7. Tergites 4 
and 5 with paired more or less rectangular patches of medially- 
directed microtrichia, less extensive than those of pustuliferum (cf. 
fig. 40). Sternite 8 with anterior projection as shown in fig. 62.
