mentum thickened and coarsely punctate in middle; mandibles 

 with outer portion produced in front to form a prominent lip. 

 Prothorax slightly longer than wide (7 x 6*5 mm.), regularl)'- 

 rounded on sides, median lobe prominently produced: collar-con- 

 striction rather feebly marked above, median line traceable only 

 posteriorly; finely granulate, granules rounded, rather strongly 

 setigero-punctate. Elytra (13 x 8-5 mm.) short, widened from 

 shoulders to behind middle, thence subparallel to apex, strongly 

 declivous posteriorly; apex mucronate, base widely emarginate, 

 humeral angles marked but not produced ; disc with six 

 longitudinal stride, striae foveate, the fovese rather shallow and 

 irregular but better marked in the lateral striae; interstices raised, 

 costiform, somewhat wavy in course, setigerous; sutural interstice 

 only costiform at base, second costiform in middle, becoming 

 granular at base and on declivity, third and fifth prominent and 

 costate throughout, fourth and sixth not prominent, represented 

 each by a row of granules, seventh costate; sides irregularly 

 seriate-foveate. Metasternum with a wide median depression. 

 laterally somewhat raised and convex. Fifth ventral segment 

 widely excavate, the excavation wide, deep, short from before 

 backwards, and reaching anterior margin; preanal fossa deep; 

 intermediate ridges well marked, running from posterior border 

 at extreme edge to the side of the fossa, and bearing a row of 

 black hairlike bristles projecting downwards and backwards, 

 posterior edge also clothed laterally with a fringe of longer 

 bristles projecting downwards, and obscuring the intermediate 

 row; fascicles small, and widely separated(3"5 mm.). Forceps 

 rather short, moderately curved, clothed with black setae; laminae 

 rather small, downturned, situated obliquel}^ along base of inner 

 surface of blades, so as to be almost hidden from below. Dimen-

In its short ampliate fgrm, this species approaches to P. vario- 

 losa and P. Wilcoxi. In its widely excavate fifth ventral segment, 

 strongly hirsute posterior border and intermediate ridge it also
