LXVII.—Description of a new Searabeus fron East Africa. 
By Cuarzes O. Wateruouse, F.E.S. 
Tue British Museum has lately received some interesting 
insects from Hast Africa inland from Mombasa. Among 
them are four species of Scarabeus—S. platynotus, Bates, 
S. catenatus, Gerst., S. eratus, Gerst., and a species which [ 
am unable to find a name for. I propose to call it S. Betton?, 
after the collector Mr. C. Stewart Betton, to whom we are 
indebted for the specimens. 
Scarabeus Bettont, sp. n. 
Oblongus, sat convexus, nitidus, piceo-niger; thorace sat crebre 
granulato, basi medio fere levi; elytris distincte striatis, inter- 
stitlis vix convexis, nitidis, punctis parvis sparsis, lateribus 
bicarinatis; tibiis anticis quadridentatis, dente basali parvo; 
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 trom Abyssinia 
and Uganda), but it isa little longerin theelytra. The head 
is densely asperate, without any frontal tubercle. The thorax
