joint furnished, on the venter, with a tuft of golden setae at the 
extremity; onychium present; intermediate and posterior tibiae 
sparingly clothed with short golden setae increasing in length 
and density toward the extremities. Beneath deep chocolate- 
brown, glabrous; maxillary and labial palpi reddish; mentum 
feebly bilobate in front, laterad rounded, nearly as long as 
broad, roughly sculptured by large confluent pits; genae simi- 
larly sculptured as the top of head behind the eyes; prosternal 
process prominent, terminating in an obtuse point; abdominal 
segments emarginate, with a few scattered punctures, shining. 
Length, without mandibles, 17.5 mm.; mandibles 2.75 mm. 
Female unknown.

Closely allied to the Sumatran P. rubens Didier, 2 from which 
it can be readily separated by its dark coloration (bright ma- 
hogany red in rubens ), shorter mandibles, broad pronotum (in 
rubens not broader than the head, laterad parallel, overlapped 
by the postocular spine), ovate elytra ( rubens distinctly paral- 
lel) and the granulose sculpture ( rubens smooth, shining). 
Lissapterus monti vagus n. sp. Figs. 2, 2a, 2b 
Robust, convex, black, feebly shining; allied to L. tetrops 
Lea, and L. hopsoni Carter. 
$ Head transverso-quadrate, convex, front sloping, clypeus 
small, conical, not exposed; anterad broadly concave, angles 
rounded to canthus, latter completely dividing the eyes; eyes 
small, larger, however, than in tetrops\ behind the eyes with 
an acuminate process, narrowing to base; above the eyes an 
oblong, deep cavity, extending to opposite the center of the 
acuminate process; above and behind the cavity, to base, 
strongly beset with large pits, which become nearly obsolete on 
the occiput. Mentum (fig. 2b) transverso-trapezoid, feebly 
lobed in front, with a central kidney-shaped excavation, finely 
granulate; strongly and distantly pitted toward margins, an- 
terior and lateral pits bearing a seta, base nude. Mandibles 
symmetrical, porrect, regularly curved, laterad rounded, in 
distal half with an acute, upward and slightly inward directed 
tooth, and, on the inferior margin, in the basal third, another
