128 On the Gofee-borer 



Clytus includes lama, arietis, and rhamni ; Antliohoscvs 

 includes trifasciatus, ijleheius, and Massiliensis ; whilst Iso- 

 tormis is composed oi semipunctahis and comptus. 



In 1863 M. Chevrolat's " Clytides d'Asie et d'Ocranie" 

 appeared. Amongst other new genera^ Gldoropliorus (p. 

 38) is proposed for annularis and its allies. Anthohoscus 

 (now a genus) includes ornatus, Macaonensis j"^ pleheius, 

 perspicillus , and numerous other species. Clytus in- 

 cludes forah's. XylotrecJms (now also a genus) is divided 

 into nine divisions, the third of which is sub-divided 

 into three groups ; amongst the 27 Asiatic or Oceanic 

 species enumerated are quadripes, vicinus, Lap. & Gory, 

 and ihex, Humm. (said to be allied to arvicola) . At 

 p. 81, the genus Sphegestlies is founded, and arietis, 

 rhamni, lama and arvicola are referred to it, together 

 with the capra of Germar. 



Lastly, the " Systema Cerambycidarum " of Mr. James 

 Thomson was published in 1864. In this work the author 

 abandons the limits of Clytus and Xylotreehus as defined 

 in the ^^Essai" of 1860. The original limits of Clytus 

 as defined by Von Laicharting in 1784 are now adopted, 

 (p. 186), arietis is re-instated as the type-species, and 

 Europa (=i2nd div. of Xylotreehus, Thorns. 1860), Sphe- 

 gestlies, and Echinocerus, are sunk as synonyms. Antho- 

 hoscus, Chlorophorus , and Isotomus ( = 3rd div. of Xylotre- 

 ehus, Thorns. 1860), are merged to form the genus Clytan- 

 tlms (p. 190), the names Anthohoscus and Chlorophorus 

 being rejected on account of their having been already 

 employed for genera of insects, whilst Isotomus is dis- 

 carded as being a " nom trop voisin de celui d' Isosonms f f 

 the type-species of Clytanthiis being tricolor, the original 



* This species was first described by M. Clievrolat, nt p. 98 of the Eev. 

 Zool. 1845, in a paper entitled " Description de dix Coleopteres de Chine 

 des environs de Macao." By a typographical error the name is there 

 printed Macawmensis ; and by a second error, the insect appears in the 

 " Clytides d'Asie" (p. 45) as Anthohoscus Macausnensis. 



+ See a note by Mr. Pascoe " On generic Names having nearly the same 

 Sound," inProc. Ent. Soc. 1865, p. 85, in which it is stated that Mr. James 

 Thomson had previously changed the name Orthostomahecanse of its sup- 

 posed resemblance to Orthogowa. I can only suppose that Mr. Thomson is 

 in the habit of speaking of Orthosoma and IsosOmus ! But if the derivation 

 of the names be attended to, there is no very great fear of confusion between 

 Orthostuma and Orthosoma, or between Isotonuis and Isosomus. A better 

 reason for the rejection of Isotomus would have been the fact that the 

 same name has been ai>plied to a genus of plants ; but according to 

 modern notions this is an iusuiScient ground, and botanists have now 

 ceased to discard names pre-occupied by zoologists. Zoologists however 

 will do well to avoid the intentional use of generic names already employed 

 by botanists. Factum valet, fieri non dehet.
