100 Mr. T. V. Wollaston on the Canarian Longicorns. 
have altogether escaped the observations both of myself and other 
recent collectors in those islands. Nevertheless, since one of these 
three (the C. Webbii) was considered even by M. Brullé to be iden- 
tical with the C. 4-punctatus, Fab., I think it is more than possible 
that the specimen (or specimens) on which their admission into the 
fauna respectively rests was a mere chance importation, picked up by 
Mr. Webb in or near some one of the towns. At the same time I 
must confess that, until the ancient Pinals of a high elevation have 
been accurately examined, I would not wish to treat this (however 
probable) as more than a conjecture, inasmuch as I cannot but feel 
a suspicion that they may perhaps (all or in part) have been pro- 
cured from the old pine-forests, whence, at any rate, a few of Mr. 
Webb’s insects unquestionably came. Be this, however, as it may, 
I think certainly that the chances are in favour of their having been 
accidentally introduced (possibly with foreign timber); and therefore 
I consider it safer for the present to place them amongst the forms 
whose claims to be truly indigenous, to say the least, require corro- 
borating. 
Whether the Clyti, however, and the Hesperophanes roridus be 
naturalized or not, I believe that the other four species (namely, the 
Hylotrupes bajulus, Criocephalus rusticus, Hesperophanes senex, and 
the Gracilia pygmea) most decidedly are so; and I am equally 
satisfied that the remaining nine included in this paper are strictly 
and emphatically indigenous—their modus vivendi, and other local 
considerations, rendering this to my mind quite unequivocal. So 
that, when we take into account the excessive scarcity of the Longi- 
corns in the various Atlantic Islands (only three out of the eleven 
species of the Madeiran group being positively endemic), it will be 
admitted that nine for the Canaries is a larger number than would 
have been @ priori anticipated. 
In the following pages I have marked those species with an 
asterisk which I imagine to be essentially, and without doubt, truly 
indigenous.
