Mr. C. 0. Waterhouse communicated the following " Synonymical Notes 

 on Longicorn Coleoptera : " — 



" Fam. Pkionid^. 



Acanthophorus Palinii, Hope. This species was placed by Mr. Adam 

 White, with doubt, as Acanthophorus Yolofus of Dalman, and in Gemmiuger 

 and Harold's ' Catalogue of Coleoptera ' they are placed together without 

 even a doubt. There being, however, in the British Museum a species of 

 Tithoes (to which genus A. Palinii must now be referred), which I believed 

 to be the true A. Palinii, I referred to Prof. Westwood, who kindly sent to 

 me a sketch of Hope's type in the Oxford Museum, confirming my deter- 

 mination, and making it certain that A. Yolofus and A. Palinii are quite 

 distinct species. Tithoes Palinii resembles T. confinis, but is shorter ; the 

 eyes are much approximated above ; the thorax is broadest in front, with 

 the anterior spine strong (much longer than the lateral spine), and very 

 much recurved; the elytra are marked much in the same way, but the 

 apex of each elytron is less rounded and there is a small tooth at the sutural 

 angle. Length 1 inch 10 lines ; width 8 lines. Habitat, Sierra Leone. 



Acanthophorus capensis, White. This species is correctly placed in 

 that genus, and does not belong to Tithous, as placed in Gemminger's 

 Catalogue. 



Mallodon gnatho, White. This insect must be placed in Lacordaire's 

 genus Nothopleurus (Gen. d. Col. viii. p. 125). As nothiug is said by 

 Lacordaire about the form of the mandibles in the description of N. ebeninus, 

 it will probably prove to be a species distinct from M. gnatho, which has a 

 remarkably large triangular tooth on the upper edge at the base of each 

 mandible. The thorax of M. gnatho has parallel sides. 



Tragosoma suhcoriaceum, Hope, female, 1831. The male of this insect 

 was described in 1867 by Mr. Pascoe, under the name Sarmydus anteu- 

 natus. 



Fam. CERAMBYC1D.E. 



Eburophora, White {Eburigera, Gemm. & Harold, Cat. p. Q899). This 

 genus should be placed next to Sophron, Neicm., and Sophrou eburatus, 

 Pascoe, should be transferred to it. 



Trichoxys flexus, Chevr., 1860 = Clytus melauotelus. White, 1855. 

 (Types compared.) 



Anthoboscus figuratus, Pascoe, 1869 = Clytanthus margiualis, Chevr., 

 1863. (Types compared.) 



Anthoboscus leucothyreus, Pascoe, 1869 = Clytanthus austerus, Chevr., 

 1863. (Types compared.) 



Clytanthus opjjositiis, Chevr., 1863 = Clytus signaticollis, Lap. d Gory, 

 but with the pubescence rubbed off the abdomen ; it is not a synonym of 

 C. japonicus, as suggested by Mr. Bates, Ann. & Mag. Nat. Hist., 1873.
