chosen from its similarity to Oberea. It is so seldom that the ety- 

 mology is expressive, that I seldom give it, considering that generic 

 names should be used as proper names, as in the case of Cicindela, 

 Lamia, &c. 



204. Amphyonycha marginata F. Hab. Georgia. Syn. Saperda 

 flammata Nm. 



205. Distenia undata F. Hab. New York, Penna. and Georgia. 

 It has a disagreeable scent when recent. 



208-9. The Genus Rhamnusium was inserted doubtfully on the 

 strength of Dr. Harris's comparison of his insect with the European 

 Rhamnusium. Having recently seen his specimen, I find it identical 

 with Toxotus rubidus ; it will accordingly be called Toxotus decolora- 

 tus Harris. It has been found at Niagara. 



213. Toxotus cylindricollis S. Probably dives of Newman. 



215. Toxotus sesculi =: cinnamoptera Randall (Leptura), Bost. J. 

 2,45. Mass. Car. 



225-6. These are identical, but the true Pachyta leonardii, re- 

 cently shown to me by Dr. Harris, is my No. 259 Leptura mala- 

 chiticus. 



232. Var. solitaria, hab. Alab. Missouri. For confluenta read 

 confluens. 



238. S. zebrata (?). S. aurigera Nm. seems to be a synonym of 

 this species, rather than of S. velutina. The zebrata noticed by me 

 seems not to be that of Fabricius, whose description requires black 

 antennae, which would associate it with zebra. 



241. S. velutina. Pa. July. A variety occurs in which the elytra 

 are of a uniform reddish colour, clothed with yellowish sericeous. 

 North-west Illinois. 242. S. fugax is probably the male. 



243. S. luridipennis is identical with mutabilis Nm. 



255. For cinnamoptera read erythroptera Kb. as the erythroptera 

 of Zenker was published in Germar's Species, in 1825, whilst Say's 

 rubrica (No. 256) was published in 1824, and must consequently 

 take precedence. 



259. L. malachiticus, of which my cyaneus, (Proced. Acad. Nat. 

 Sc. 3,151,) is a variety. It, with L. vagans, comes better under 

 Pachyta. 



272. Leptura semivittata seems to be vittata No. 261. 



277. L. proteus. Omit biforis. 



281. Anoplodera 4 vittata, var. pallida, is Newman's directa. 



285. Prionus fissicornis Hald. Proceed. A. N. S. 3,125. 



286. Sphenostethus serripennis Hald. id., 126. Alluded to but
