150 M. Louis Peringuey on new genera and species of 



very deeply sinuate laterally in the middle, and -with an arcuate 

 transverse median narrow and shallow impression ; the anterior 

 part of the disk is hardly more raised than the posterior, and 

 slightly aculeate in the posterior angle above the constriction, 

 when there is also a very small, pubescent, yellow tuft ; elytra 

 parallel, deeply and closely punctured, each puncture bearing a 

 short seta ; pygidium punctulate and setulose ; femora a little 

 swollen, tibiee slender. Length U, width 2^ ram. 



Hah. Zambezia (Salisbury). 



The nearest ally of P. manicaniis is P. planicollis, RafFr., 

 from Abyssinia. The shape of the prothorax is identical ; 

 the head is equally depressed, but has no trace of a minute 

 conical tubercle at the extreme apex; the antennal club is 

 of a shape similar to that of the S of P. plauicoUis, but 

 not so long, and therefore a little broader in proportion. 



P. r affray I, n. sp. 



Piceous-black, with the apical part of the elytra and the tarsi 

 reddish-brown ; head rugulose, with the anterior part deeply im- 

 pressed in the centre and the walls of the impression raised in two 

 short tuberculif orm processes, posterior part bi-impressed ; club of 

 the antenuEe sub-ensiform, very long, compressed, external margin 

 with a moderately wide groove reaching from the base to near the 

 apex, both margins of the groove very faintly notched ; prothorax 

 bi-partite, the anterior part raised, smooth, the median transverse 

 cavity wide and deep, and having two pubescent yellow patches in 

 the centre, posterior part depressed and with three tuberculated 

 indentations ; elytra elongate, sub-parallel, shining, moderately 

 punctured, each puncture with a very short greyish hair ; femora 

 not thickened ; anterior and intermediate tibiiB slender, posterior 

 tibife broadly dilated and flat. Length 5, width H mm. 



Hah. Natal (Frere). 



The shape of the club of the antennee is not' unlike 

 that of P. germari ; it is however longer, more curved 

 outwardly, and not attenuate at the tip. 



P. concinnus, n. sp. 



Head, prothorax and legs brick-red ; elytra black, edged with 

 red at the base and apex ; head and prothorax glabrous, the former 

 edged in front on the vertex with a high semicircular ridge, which
