5. Of a more oval form, apex more gradually produced. Head 

 and prothorax(5 x 6 mm.) as in (J, but prothoracic impressions 

 absent; elytra(14 x 9 mm.) more rounded on sides, apex not 

 mucronate, shoulders slightly more prominent, sculpture less 

 regular; undersurface slightly convex, fifth ventral segment with 

 a well defined median impression not reaching base or apex. 

 Dimensions : (J, 20 x 8 mm.; ^, 20 x 9 mm.

Close to the preceding species, and to P. impressa-, the form of 

 the laminse will at once distinguish it from the latter. From P. 

 cultrata it differs in its more parallel-sided form, and somewhat 

 differently sculptured elytra; the depressions in the elytral strise- 

 are smaller and much more irregular, while the intrastrial 

 granules are more prominent; the forceps are as in P. cultrata^ 

 but the laminae merely meet at the apex and do not overlap; the 

 penis is also differently shaped; the abdominal fascicles are 

 slightly further apart, and somewhat differently set.

^. A small parallel-sided species, without evident forceps. 

 Black, legs red; sparingly clothed with muddy-brown scales^, 

 negro-setose. 



Head convex, rostral ridges flattened, sulci obsolete at base,, 

 median area strongly depressed; mentum bearded, dentate ante- 

 riorly. Prothorax(6'5 X 6-5 mm.) rotundate, apex slightly pro- 

 duced, feebly depressed along median line; very finely and closely 

 granulate. Elytra almost parallel-sided, scarcely wider than 

 prothorax (13 X 7 mm.); base arcuate, shoulders tuberculiform; 

 strise transversely ridged, almost foveate, interstices not much 

 narrower than striae, finely granulate in double series throughout 

 except on declivity, where they are in single series, but closely 

 placed and not larger than on the rest of the interstice. Meta- 

 sternum concave, the lateral borders raised in the form of a 

 distinct tubercle to the level of the middle coxae. A pical segment 

 deeply excavate, the excavation reaching anterior margin for a 

 considerable distance on either side of the middle line; fossa deep, 

 transverse, running out towards each postero-lateral angle;.
