the scape and only slightly nodulose at the apex ; the fifth 
joint is a little shorter than the third and longer than the 
fourth. The prothorax is strongly constricted and transversely 
grooved anteriorly, obtusely tubercled both at the sides and 
on the disk, and rather strongly and irregularly transversely 
wrinkled above. Prosternal process strongly arched, sub- 
vertical behind. Underside of the head crossed by two trans- 
verse grooves separated by a rather narrow ridge. 
With antennas rather long for the genus, the remaining 
characters of this species seem to point conclusively to its 
place in Taurotagus. 
Taurotagus griseus , G u£r. 
The type of this species (a female specimen) was one of 
those so kindly sent to me by M. Rene Oberthiir, but was 
too old and faded to admit of close comparison with other 
species. I believe, however, that I am right in referring to 
the species two male specimens — one, from Senegal, in the 
British Museum collection, the other, from Abyssinia, in Mr. 
Fry’s collection. In these the antennae are not more than 
three fourths of the length of the body, with the third joint 
only about equal in length to the scape. The prothorax is 
slightly uneven and without any distinct rugosity above. 
The elytra are about three and a half times as long as the 
prothorax and are rounded at the apex. The prosternal 
process, gradually rounded and declivous posteriorly, is feebly 
tubercled in the middle near its extremity. 
The British Museum specimen is the Hammaticherus cine- 
rarius ) Buq., of Dejean’s collection. 
Cgelodon, Serv. 
The Prionus cinereus of Olivier has been incorrectly quoted 
by Serville, Lacordaire, and others as the type of this genus. 
The cinereus of Olivier, as a reference to his description and 
figure will easily prove, is a species of Griodion , and the 
habitat he ascribed to it is without doubt correct. The type 
of t Ccelodon — an African species described by Serville — must 
therefore be written G. cinereum , Serv. As a synonym of 
this species we may add G. servum , White ( Hammaticherus ) . 
White described his species from a female example of 
unknown locality. This specimen agrees with a female, of 
much smaller size, from Masai-land, and with a male from 
Abyssinia, both of which I have referred to G . cinereum , 
Serv.
