CERAMBICID^E. 347 



Canaries of this Clytus (which is probably a mere variety of the com- 

 mon European ^-punctatus) rests on the most meagre and unsatis- 

 factory evidence. It appears that both Gory and M. Brulle cited it 

 as Teneriffan on the authority of a specimen in the collection of Mr. 

 Webb, who seems to have so confused its habitat as to have reported 

 it loth for Madeira and the Canaries. But as I possess the most 

 conclusive evidence of Mr. Webb's unpardonable inaccuracy in mix- 

 ing up his Madeiran and Canarian material, this perhaps is not to 

 be wondered at. My own belief is that the species pertains to neither 

 of these Atlantic Groups ; though it is far from unlikely that an 

 accidentally imported example may have been captured by Mr. Webb 

 in one or the other of them, and afterwards described by Gory as a 

 distinct species. And I certainly should not have admitted the C. 

 Wcbbii into the present Catalogue at all, had it not already been cited 

 as Teneriffan in two separate works*.

Habitat Salvages (ins. majorem, borealem), a Barone Castello de Paiva 

 communicatus. 



It is a most remarkable fact that this strictly North- American 

 Clytus should occur in any of these Atlantic Groups above all, on 

 the remote, uninhabited, and almost inaccessible rocks of the Salvages. 

 Yet a single example has lately been communicated by the Barao do 

 Castello de Paiva, who certainly obtained it from the larger (and 

 more northern) island known as the Great Salvage ; and after a 

 careful comparison of it with American ones, I can see nothing to 

 warrant the suspicion that it is specifically distinct. The small raised 

 transverse lines on the disk and posterior region of its prothorax 

 differ a little, in shape and development, from those on the ordinary 

 type ; but it is so little, and the insect is altogether so well defined, 

 that such slight discrepancies are scarcely worth alluding to, and 

 afford no evidence whatever of anything approaching to a specific 

 character. 



As the existence of this Clytus on the Salvages is a unique fact, 

 it must probably be dependent upon something altogether excep- 



* Cf. the remarks on this Clytus at pp. 389 and 390 of my Canarian Cata- 

 logue, as also the reasons for rejecting the C. griseus, which is quoted as Canarian 

 by MM. Gory and Brulle.
