ohlongis ( $ ), angulo suturali dentato, dorso confertim grosse punctatis : cor- 

 pore subtus cyaneo-violaceo, coxis femoribusque basi viridi-csneis pedibus 

 nigris : antennis Jiliformibus, gracilibus. Long., 15 mm., ? . 



Distinguished from all other described species by its elytral 

 markings— two round whitish spots on each, distant from the margin, 

 by the obtuse costa down the centre from the base nearly to the 

 apex, on which the punctures are less dense than on the rest of 

 the surface, and by the short and broad head, broad and flattened 

 between the very prominent eyes, and suddenly narrowed behind. 

 The elytra are moderately narrowed towards the base and have 

 distinct humeral angles.

Chaudoir confounded this species with the much commoner West 

 African O. Savagei, of Hope, apparently not having studied Schiodte's 

 excellent description and figure, in which the broadly flattened penul- 

 timate joint of the labial palpi, the longer and straighter mandibles, 

 the frontal cavity, the peculiar form of the thorax, and the absence of 

 conical projection behind the eyes, are clearly described and figured. 

 The middle tibife have a row of short strong spines on their outer 

 edge above the sub-apical spine ; in O. Savagei the short spines are j 

 reduced to small denticulations. The maxillaB are curved and pointed 

 at the apex ; in O. Savagei they are broadly obtuse. According to 

 Chaudoir's classification this would place the two species in different 

 genera and in different chief sections of the sub-family ; the form of 

 the mentum is also different and the side lobes quite free from 

 thickened margins, whilst they are margined in O. Savagei, as in the 

 restricted genus Scarites. The species is found in West as well as 

 in East Africa, in similar latitudes.
