fossulate on each side of the feeble, abbreviated, median carina ; 
frontal costa strongly protuberant between the antennze and rather 
narrowly suleate ; superior ocelli placed between the submedian part 
of the eyes, visible in profile ; antenne inserted little anterior to and 
scarcely below the ventro anterior margin of the eyes, filiform, but 
the fifth and sixth articles little compresso-expanded, the seventh to 
ninth distinctly compresso-dilated, the two apical articles minute, 
the apices acute. Pronotum anteriorly little rounded produced, pos- 
teriorly acuminate, extended little beyond the apices of the posterior 
femora ; anterior prozonal carine behind the anterior margin want- 
ing, median carina little acute, percurrent, in profile substraight ; 
anterior sulci subobsolete, humeral angles wanting, the humero- 
apical carine percurrent backward, and forward extended as far as 
the point opposite and above the inferior sinus ; lateral lobes turned 
down, the posterior angles obtuse. Elytra small elongate, sub- 
lanceolate ; wings fully explicate, extended to or little beyond the 
apex of pronotal process. Anterior and middle femora elongate, the 
margins straight, entire ; the posterior femora little incrassate, the 
superior margin arcuate, minutely serrulate, posterior tibie pluri- 
spinose and minutely serrulate, the inner fourth part toward the 
apices unarmed, the three pulvilli of the first article of posterior 
tarsi equal in length, subacute. Length of body, female entire, 
95-10 mm. ; posterior femora 5-55 mm. 
Three examples from Kuching, N.W. Borneo; two of 
these from the Sarawak Museum, No. 337 and 357, and 
the other Dyak coll., R. Shelford; Oxford Museum. 
The antenne in this species are more compressed than 
in P. mellerborgi, Stal, and the facial frontal costa is more 
narrowly sulcate.

These specimens have the pronotum less produced 
anteriorly than the type examples in the author’s collec- 
tion, from the same locality, and are provisionally con- 
sidered immature. It is however possible that they are
