LXVII. — Description of a nero ScarabfEus from Eist Africa. 

 By Charles O. Waterhouse, F.E.S. 



The British IMuscum has lately received some interesting 

 insects from East Africa inland from Mombasa. Among 

 them are four species of Scarahceus — ^S*. platynotus, Bates, 

 S. catenatus, Gerst., S. ceratus, Gerst., and a species which [ 

 am unable to Knd a name for. I propose to call it >S'. Dettoni, 

 after the collector Mr. C. Stewart Betton, to whom we are 

 indebted for the specimens. 



Scarahceus Bettoni, sp. n. 



Oblongus, sat convexus, nitidus, piceo-niger ; thorace sat crebre 

 granulate, basi medio fere laevi ; elytris distincte striatis, inter- 

 stitiis vix convexis, nitidis, pxmctis parvis sparsis, lateribus 

 bicarinatis ; tibiis anticis quadridentatis, deute basali paryo ; 

 mesosterno antice dense fulvo-hirto. 



Long. 44 millim. 



This species belongs to the metallicus group, but is pitchy 

 black, shining. It is very close to S. venerabilis, Harold (of 

 which there are specimens in this Museum from Abyssinia 

 and Uganda), but it is a little longer in the elytra. The head 

 is densely asperate, without any frontal tubercle. The thorax
