five impressions the edges of which are broad and shining ; the first 

 impression is diamond- shape, placed in tlie centre of the disk, and 

 has two slanting ones under it, nearly abutting against a supra-lateral 

 one more or less deep or broad ; elytra nearly plane with the 

 humeral angle a little oblique, slightly attenuate towards the apex, 

 very narrowly striate ; the intervals are very finely shagreened and 

 have a double series of aciculate punctures ; lateral margin bi-cari- 

 nate, suture slightly gibbose at middle ; pygidium finely aciculate ; 

 intermediate and posterior tibiae fringed with a short thick black 

 pubescence ; anterior femora extremely massive, sharply carinate in 

 the anterior margin, with the ridge serrulate and pluri-dentate ; 

 those of the S^ are thicker still than in the ? , and have a sharp 

 tooth under the marginal one ; anterior tibiae distinctly quadri- 

 dentate outwardly, and with one or two serrate teeth next to the 

 digitation, sub- falcate internally and provided with a non-serrate 

 lamina ending in a distinct blunt tooth in a line with the outer basal 

 one ; metasternum with a deep groove with rounded walls between 

 the intermediate coxae, and an elongate impression with a narrow 

 median line disconnected from the anterior groove, sides of meta- 

 sternum very finely granulose. 



Length 34-38 mm. ; width 21-28 mm. 



Hah. Transvaal (Eustenburg, Lydenburg) ; British Bechuana-

" Near P. femorata, Kirb. ; it is easily distinguished besides its 

 smaller size by the following characters : the teeth of the clypeus 

 are stronger, the longitudinal carina on the vertex is missing, the 

 head is less broad, the prothorax is wider at base and has a more 

 triangular shape, the posterior angles are recurved in a spine, while 

 in P. femorata they are nearly rounded, it is more distinctly granu- 

 late, and instead of the stronger granules seen m. femorata , there are 

 a few scattered punctures ; the elytra are more plane, equally 

 granulose all over without any trace of scattered punctures, and are 

 less distinctly striate ; the anterior tibiae have no vestige of a fifth 

 outer tooth." 



This description is based on one example only from Lake N'Gami, 

 and I have not been able to identify the species.
