bears a short ridge, the vertex a transverse, tri-dentate lamina 

 situated a little behind the eyes ; prothorax closely, moderately finely 

 granulate, depressed in front ( ? ) and bearing a little past the third 

 anterior part a minute longitudinal tubercle ; the sides are slightly 

 sinuate behind, the base angularly produced in the middle but little 

 distinctly emarginate towards the sides, but more distinctly so 

 towards the median part ; elytra not longer than the prothorax, very 

 finely striate, intervals plane, closely and finely granulate ; pygidium 

 finely, but little densely granulate. 



Length 13 mm. 



Hab. Portuguese East Africa ( ? ). 



Resembles in shape and in granulation the ? of 0. panoplus, Bat. ; 

 differs by the clypeus, which instead of being " ogival " is pro- 

 duced into a small tooth ; the disk of the prothorax bears a small 

 longitudinal tubercle instead of a strong transverse carina divided 

 into two tubercles, and the granules of the elytra are very closely set 

 instead of being remote." 



I am not aware of this species having been, as yet, recorded within 

 the South African limit.

 0. por rectus, Fahr., nee Eeich., Col. Caffr., ii., p. 263. 



Dark blue or bluish green, moderately shiny, glabrous, antennae 

 fuscous. 



Male : Clypeus obtuse and slightly sinuate in front, covered with 

 deep asperous, closely set punctures with the walls somewhat 

 transversely plicate, anterior frontal part with an arcuate carina 

 reaching from one gena to the other ; immediately behind it is an 

 upright lamina nearly equal in height to half the width, and each 

 angle of which is produced into a long, incurved horn bearing at about 

 one-third of the length an inner vertical spur or ramus, the length of 

 this horn reaches to about two-thirds of the length of the prothorax, 

 the central part of the lamina supporting the horns is arcuately but 

 not deeply emarginate, the whole frontal part of the same lamina is 

 very closely pitted ; the prothorax has a very deep, median anterior 

 excavation reaching closely to the lateral fossa, and surmounted in 

 the centre by a compressed laminate horn, somewhat ampliate 

 towards the tip, and rounded there, projecting forward, but neither 

 horizontally nor vertically, and of about the same length as the 

 posterior part of the prothorax, which is somewhat closely aciculate
