complete, inner humeral and 1-3 dorsal strong, complete, and 

 similar in having the outer edge somewhat elevated, the third 

 dorsal is rather less strong than the second, 4 dorsal and the 

 sutural are fine and almost complete, being joined anteriorly, 

 but they are slightly shortened apically, 5 dorsal is apical,

fine, and reaches just beyond the middle. The propygidium 

 and pygidium are clearly punctulate ; the presternum is bi- 

 striate, striae divergent posteriorly ; the inesosternum is like 

 that of the last species, except that the fine marginal stria is 

 conspicuously complete anteriorly ; the metasternum is striate 

 laterally and the suture is marked by a fine transverse stria ; 

 the legs are similar to those of P. africanus.

Ovalis, parum convexus, niger, nitidus ; fronte punctulata, stria 

 laterali perspicue angulata ; pronoto stria laterali Integra ; elytris 

 striis 1-4 suturalique integris, 4 cum suturali arcuatim connexa,

Oval, rather convex, black and shining ; the head punctu- 

 late, punctures varying in size, with very minute points 

 intermixed, lateral stria rather strong and very distinctly 

 angulate in the middle, area behind the epistoma is very 

 faintly impressed; the thorax punctured like the head, except 

 along the base, where the punctures are larger, lateral stria 

 entire and feebly crenulate behind the neck ; the elytra, the 

 stria} resemble those of P. permundus, except that the fourth 

 and sutural are not shortened at the apex, the surface punctu- 

 ation is only seen under the microscope and consists of 

 extremely fine points ; the propygidium is margined laterally 

 with a very fine stria, surface clearly not closely punctate, 

 with very fine points intermixed ; the pygidium is curiously
