248 Mr. C. J. Galian on Longicorn Coleoptera 



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 antennee 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. Ren^ 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 antennse 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 Dej can's collection. 



CcELODON, 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 Criodion, and the 

 habitat he ascribed to it is without doubt correct. The type 

 oi^Ccelodon — an African species described by Serville — must 

 therefore be written C. cinereum, Serv. As a synonym of 

 this species we may add C. 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 C. cinereum^ 

 Serv.
