margin with an elongate triangular fulvous spot reaching 

 from apex to beyond middle; membrane hyaline ; ventral 

 segments with a pale yellow spot at the apical angles ; 

 antennae with the first two joints testaceous, the basal one 

 with a fuscous streak on each side, the last three joints 

 fuscous black, with the base testaceous; rostrum and legs 

 pale testaceous, the former with the last joint fuscous. Head 

 impunctate, but with an impressed punctate area at the 

 exterior base of the juga and an impressed punctured longi- 

 tudinal line on each side of vertex before the ocelli, which 

 are as remote from the eyes as from each other, antennae as 

 long as the body without the anal spines, first joint distinctly 

 passing apex of liead, second as long as third which is a 

 little shorter than fourth and conspicuously longer than fiftii, 

 rostrum reaching apical margin of third ventral segment. 

 Pronotum, except the sraootli transverse elevated subapical 

 area, strongly but very irregularly punctate, the whole 

 posterior part (behind the elevated transverse area) with an 

 anteriorly widened median line, an oblique sublateral vitta, a 

 rounded spot inside this, and some smaller anterior spots and 

 waved transverse lines impunctate, pronotal lateral margins 

 straight. Scutellum coarsely punctate, postfrenid part finely 

 punctulate, a small callus at tiie basal angles, a percurrent 

 median line, and the apex impunctate, the lateral margins 

 slightly sinuate at apex of f rena. Pectus impunctate, a trans- 

 verse row of fuscous punctures near apical margin of pro- 

 sternum, ])osterior part of propleurae remotely punctured with 

 fuscous, median keel of mesosterimm low and very narrow. 

 Henielytra passing apex of genital segment by nearly one- 

 third the length of the menib'.ane, corium strongly punctured, 

 mesocoiium in the basal half of its exterior border impunctate. 

 Abdomen impunctate, beneath in the female rather deeply 

 and broadly longitudinally sulcate down the middle, the 

 furrow narrower and less deep in the sixth segment, at the 

 base of which it is narrowly interrupted, apical spinelets of 

 fifth segment somewhat curved, apical spines of sixth segment 

 a little longer than genital segment and last ventral segment 

 taken together, passing apex of membrane, directed straight 

 backwards, but curved a little outward at the base and a little 

 upward at the apex. 



Length (excl. membrane and anal spines), ? , 7*5 mm. 



Philippine Islands : Mt. Banahao, Luzon (6*. F. jBaker). 



More nearly related to P. colax, Bredd., than to any other 

 known species, but very distinct in several characters. 



To Breddin's very good generic description I have only to 

 add that tlie evaporative area is large, transversely oval,
