reaching from base to apex, and also a diagonal sub-basal, elongate 

 impression on each side of it, not reaching quite the median part ; 

 elytra slightly rugose, very faintly striate with the intervals plane, 

 and having a very inconspicuous series of minute granules ; pygi- 

 dium slightly granular ; legs as in the preceding species, but the 

 anterior tibiae are dilated inwardly from the apex to about the 

 median part and bluntly serrate, and there is only one serrate tooth 

 beyond the basal outer one ; the metasternum has no impression 

 between the median coxae ; the abdominal segments are as in the 

 preceding species. 



Length 32 mm. ; width 20 mm. 



Hah. Cape Colony (Malmesbury). 



I have not been able to examine a female of this species.

Black, opaque ; head rugulose at base, with the central and apica 

 part of the clypeus smooth, lateral lobes granular, the two front teeth 

 of the clypeus sharper and a little longer than in P. cESCulapius and 

 P. hippocrates; prothorax similar in shape, sharply and closely serrate 

 laterally, and punctato-serrulate along the base, nearly shagreened 

 and besprinkled with very distinct, not closely set granules ; the 

 disk has a very indistinct longitudinal median smooth line ; in the 

 (^ the granules of the central part of the disk disappear and foveate 

 punctures take their place ; elytra orbicular, broader in the middle 

 than the thorax at its widest part, striate and having five intervals 

 convex and in some examples sub-tectiform, the juxta-marginal space 

 is depressed and closely granulate, and each interval has a series of 

 smaller granules; in the female the granules have a tendency to 

 become bi-seriate on each alternate interval ; outer margins sharp, 

 nearly bi-carinate and slightly serrulate ; pygidium granulose ; legs 

 strong, fringed with dense, long fulvous hairs ; anterior tibiae quadri- 

 dentate outwardly, those of the male broadly mucronate inwardly 

 at tip, and having five sharp, straight, equi-distant spines in the 

 inner curve ; posterior tibiae in the same sex incurved a little at 

 middle and serrate from the curve to the apex ; in the female the 

 anterior tibiae have no inner teeth nor are they bluntly mucronate 

 at tip ; femora deeply pitted but not granulose ; metasternum not 

 impressed betvv''een the intermediate coxae. 



Length 20-27 mm. ; width 14-17 mm. 



Hah. Cape Colony (Namaqualand).
