the clypeus which is deeply arcuately emarginate, black ; prothorax 

 with two median fusco-rufescent longitudinal bands acuminate at 

 the apex and a supra-marginal spot of the same colour in the 

 anterior part, the margin itself is very narrowly infuscate all round ; 

 scutellum with the sides narrowly fuscous ; elytra with a quadrate 

 discoidal patch deeply incised laterally and reaching short of the 

 median part, continued as a narrow, sutural line and expanding past 

 the middle in a transverse band wider than the anterior patch, and 

 connected with a supra-apical transverse band of not quite the same 

 width by a short, longitudinal patch, this apical band is sometimes 

 disconnected near the suture, there is also a large humeral infuscate 

 spot ; the greatest part of the pygidium is flavescent, the margins 

 being, however, darker. Head, clypeus, and prothorax deeply 

 punctate, the punctures somewhat closely set ; the elytra have 

 shallow punctures indistinct on the sides, seriate and fairly distinct 

 in the dorsal part ; under side glabrous ; abdomen sparsely and 

 finely punctate, pectus deeply punctate ; sternal process ampliate 

 rounded laterally, somewhat bluntly rounded in front ; pygidium 

 transversely striolate. The tooth of the upper maxillary lobe is 

 plainly bifid, and the inner lobe is slenderly dentate. 



I cannot decide if P. tridentata, Oliv., is identical with P. cor data, 

 Drury, but I find that the South African species of the latter are, 

 even the females, more elongated than the examples from Kumasi 

 and Senegal, the pattern of the fusco-rufescent bands or patches 

 seems to be less variable, the shape of the genital valves of the 

 males are absolutely similar. 



Length 17-19 mm. ; width 11 mm.

Green, opaque above, shiny underneath, antennae rufescent ; pro- 

 thorax with a not very broad yellow border continued along the 

 lateral and posterior margins ; pygidium with two broad median 

 longitudinal yellow bands divided by a narrow green band and a 

 small white patch at each corner of the base ; abdominal segments 

 each with a short elongated whitish flavescent band on the upper
