racterized, inter alia, by the clypeus or lowermost part of the face 

 being produced so as to form a kind of pedicel for the lip. 



Clytin^e. 

 Clytanthus. 



Clytanthus, J. Thomson, Syst. Ceramb. p. 190. 

 Anthoboscus, Chevrolat. 



Clytanthus annularis. 



Callidium annulare, Fabricius, Mant. Ins. i. p. 156; Olivier, 

 Entom. iv. no. 70. p. 48, pi. 7. f. 74. 



This species ranges from India and South China to Sydney. It 

 is the type of M. Chevrolat' s genus Chlorophorus, which, according 

 to its author, only differs from the present in its more slender an- 

 tennae and very globose prothorax. Another species in the collection 

 is allied to Clytanthus glaucinus, Bois. (Perissus, Chev.), and a third 

 species to C. sumatrensis, Lap. et Gory. A new genus, of which I 

 have four or five species, is also represented in the collection. 



Xylotrechus. 



Xylotrechus, Chevrolat, Ann. Soc. Ent. de France, I860, p. 456. 



Xylotrechus australis. 



Clylus australis, Laporte de Castelnau et Gory, Monog. du G. 

 Clytus, p. 99, pi. 19. f. 118. 



This species is also very widely distributed. I have specimens 

 from Sumatra, Borneo, Celebes, Amboyna, Am, and New Guinea ; 

 latterly I have received it from Queensland. 



Demonax. 



Demonax, J. Thomson, Essai, &c, p. 226 ; Syst. Ceramb. p. 191, 

 sub Acrocyrta. 



Demonax macilenta. 



Acrocyrta macilenta, Chevrolat, Rev. et Mag. de Zool. p. 82. 



M. Chevrolat places this species, together with several others, in 

 my genus Acrocyrta; and, in his ' Systema,' M.Thomson sinks 

 Demonax as a synonym of it. I am not prepared at present to adopt 

 this view, as I think Acrocyrta, in the short broad basal joint of the 

 anterior tarsi, long antennae, with the terminal hook in the males, 

 and the short elytra, is sufficiently distinct. M. Chevrolat, in his 

 " Cly tides d'Asie," &c, published in the 'Memoirs' of the Liege 

 Society, misquotes the volume and page of the work in which my 

 description was published, and makes me write Apocyrta. Another 

 and much smaller species is in the collection.
