CERAMBICID^E. 



I know nothing whatever about this insect except that it is figured 

 in the work of MM. Webb and Berthelot, and that the description of 

 even M. Brulle is sufficient to prevent its being identified (at all 

 events in both sexes) with any of the other Longicorns here enume- 

 rated. As no single remark of local interest is to be found, from 

 beginning to end, in the meagre list of Canarian Coleoptera which 

 M. Brulle elaborated for that gigantic History, I am of course un- 

 able to state in which of the seven islands the H. roridus is supposed 

 to have occurred. But it is far from unlikely that it was captured 

 in the town of S ta Cruz, in Teneriffe, (one of the most prolific collect- 

 ing-grounds of MM. Webb and Berthelot,) and that it was a mere 

 accidental importation from some other country. Judging however 

 from M. Brulle's diagnosis, I think it is very probable that he has 

 regarded two distinct species as sexes of his Callidium roridum, one 

 of which might possibly be identical with my H. senex ; but as I 

 could get no sight of his types, when in Paris, I cannot state this 

 for certain.

Two specimens only of this common European Clytus have as yet 

 occurred, so far as I am aware, in these Atlantic islands. They were 

 both of them taken in Madeira proper one (many years ago) by 

 the late Dr. Heineken, and the other (much more recently) by Mr. 

 Bewicke. Having been found near Funchal, it is probable that the 

 species (if indeed it be truly established, which I somewhat doubt) 

 has become naturalized accidentally from higher latitudes.
