prothorax also pubescent and covered with small granules not set 

 very closely, being separated from one another by a little wider space- 

 than that occupied by each granule, it is marginate all round, and 

 has a distinct longitudinal impression in the centre ; the elytra are- 

 somewhat elongate, and not much attenuated laterally behind, they 

 are finely but deeply striate, the intervals are nearly plane, and the- 

 eighth stria ascends only as far as the median part ; pygidium punctu- 

 late ; metasternum deeply punctured, but smooth in the median 

 part, and having no basal impression ; posterior tarsi compressed, 

 second, third, and fourth joints decreasing in size, last one narrow, 

 Male : Clypeus very long, triangular, and with the apex of the 

 triangle recurved, deeply and broadly impressed in front of the 

 frontal carina which is arcuate, gense completely in line with the 

 clypeus, the vertex of the head is produced in a broad laminate 

 process as broad as the head itself, and as long, or longer than the 

 head and clypeus, it is slit longitudinally in the middle, rounded 

 laterally towards the tip where it curves forward a little, and ends 

 in two sharp erect spines ; the prothorax is deeply scooped for the 

 reception of the laminate cephalic horn. 



Female : Clypeus sub-semicircular, a little emarginate at tip, and 

 slightly sinuate on each side, genae straight, not projecting beyond 

 the line of the clypeus, frontal carina arcuate, vertex produced into a 



laminate process shorter than that of the male, not rounded laterally, 



but ending in a sharp outer spine, while the inner part of the median 



fissure also ends in a spine shorter than the outer one (fig. 6) ; 



prothorax also excavate for the reception of the laminate cephalic 



horn. 



In the small development of the male the clypeus is not much more 



acuminate than in the female, but it is not emarginate at tip, and the 



cephalic lamina is entirely similar. It is this development which I 



described under the name of P. boscliimanus. 

 Length 12-14 mm. ; width 7-7|- mm. 

 I have a typical example of P. clregei, Dej., from Drege's collection, 



and my examples of P. tuittei are from the same locality as those 



described by Harold.

Von Harold states (Coleopt., Heft, x., p. 205) that 0. achioer- 



sipejinis, Bohem., ex typ. is the same species as 0. prasinus, Erichs. 



I know the latter from description only, and cannot thus decide the 



point, but it is singular that this author did not recognise in 0. 



adspersipennis both his own P. clregei and 0. ivittei described five 

 years before.
