I cordially agree with Mr. Thomson both when he sinks 

 Sphegesthes and replaces arietis as the type-species of 

 Clytus, and also when he re-unites Antliohoscus, Ghloro- 

 •pliorus, and Isotomus. An author who has created Ce- 

 rambycide genera by the hundred * is not likely to err 

 on the side of too great sternness in refusing recognition 

 to the creation of others. 



If I have rightly understood Mr. James Thomson, the 

 three genera Clytus, GlytantJms, and Xylotrechus stand as 

 follows : t — ■ 



Gen. Clytus. 



Clytus, Laich. Tyr. Ins. ii. 88 (1784) ; nee al. and. 

 >'Clytus, Thoms. Essai, p. 217 (18G0) .

> Sphegesthes, Chevr. Clyt. d'Asie, p. 81 (1863). 



= Clytus, Thoms. Syst. Ceramb. pp. 186, 424 (1864). 



Type. — C. arietis, Lin. 



Gen. Clytanthus. 



CkjtantJmis, J. Thoms. Syst. Ceramb. p. 190 (1864) . 

 <CClytus, Fab., Lap. & G., et al. 



y Antliohoscus, Chevr. Ann. Soc. Ent. Fr. 1860, p. 455.

nee Chevr., Muls. 

 '^Isotomus, Muls. Longic. de France, p. 183 (1862). 

 ^Chlorophorus, Chevr. Mem. Soc. Sci. de Liege, 1863, 



p. 38. 

 Type. — C. tricolor, Chevr. 



Other species belonging to this genus are cmnularis, 

 Fab., bidcns,¥ah., comptus ,M.aiiiierh.., se7m2)unctatus , Fab., 

 Macaonensis, Chevr., &c. 



* " Le 8y sterna Ceramhycidarum eu a fait connaitre 1178 genres, dout 

 plus d\m tiers sont de ma creation." (J. Tlioms. Syst. Ceramb. 13.497). 



f Tlie sign = has been long used to denote that two names are syuo- 

 nymons. I venture to adopt (from the Transactions of an American 

 Society) the user of the algebraical signs > (greater than) and < (less 

 than), for the purpose of showing which is the major and which the 

 minor group, when the names are not perfectly synonymous, but belong to 

 groups which are not co-extensive. Thus Clytanthus < Clytus shows that 

 Clytanthus is less extensive than and was included in Clytus ; whilst 

 Clytanthus >■ Chlorophorus shows that Clytanthus is more extensive than 

 and includes Chlorophorus.
