with an ostiole and a narrow, upright canal on each metapleuron. 
Hypocostal lamina uniseriate. 
Pronotum almost entirely concealed by the enormous reflected up- 
right thimblelike inflated paranota; only the anterior margin of 
collum and the median and apical parts of hind process of pronotum 
visible; median carina distinctly elevated, without areolae, concealed 
by paranota on pronotal disc; lateral carinae not visible, entirely 
covered by the paranota. Each paranotum slightly longer at base 
than its greatest height (120:110), nearly vertical in front, tilted 
slightly outward. 
Elytra longer and wider than abdomen, areolae not arranged in 
very regular rows; costal area wide, mostly three areolae deep; sub- 
costal area wide, divided by a prominent, longitudinal vein into two 
parts, outer part erect and only one areolae wide, the inner part longi- 
tudinally sulcate and three areolae deep in widest part; discoidal area 
very large, two-thirds as long as elytra, acutely angulate at base and 
apex, eight or nine areolae deep in widest part, bounded on all sides 
by a prominent vein. Hind wings embrowned, longer than abdomen. 
Tyre: Holotype (female), Sandakan, Borneo, C. F. Baker, USNM

Remarks: The holotype of P. bunus is illustrated in figure 20. The 
slowly rounded outer margins of elytra, short cephalic spines, and 
narrower costal areas distinguish this species from P. oresbius, de- 
scribed immediately above.
