ries of MM. Webb and Berthelot^ which is fully deserving of 
the strong censure passed upon it by the author in his in- 
troductory remarks (p. viii). The number of species brought 
together by Webb and Berthelot was only 179^ and of these 
several did not belong to the Canarian fauna ; the researches of 
Mr. Wollaston^ Dr. Crotch^ and Mr. Gray, with some slight 
assistance from other observers, have brought up the number of 
Canarian species of Coleoptera to 930, and out ot* this largo 
number Mr. Wollaston states that only 77 have escaped his own 
personal observation. Mr. Wollaston believes that his list is 
by no means complete, and that many more species will reward 
the researches of future observers. Of the distribution of the 
species in the seveii islands composing the Canarian group, the 
author gives a table at the end of his catalogue. Its results are 
summed up as follows (Intr. Bern. p. x) : — 
Lanzarote . . . 277 
Fuerteventura . . 261 
Grand Canary . . 325 
Tenerilfe .... 539 
Gomera .... 222 
Palma 254 
Hierro .... 165 
The Coleopterous fauna of the Canaries appears to be less 
numerous in species, in proportion to their ai’ca, than that of the 
Madeiran islands, the latter group numbering 660 species*. The 
number of species known to be common to the two groups of 
islands is only 224. The numerical proportions of the main 
sections in the classification are nearly the same in both groups, 
the Bhynchophora being the most numerously represented, 
next to these the Brachelytra, whilst the Longicornia and Hy- 
dradephaga occupy the opposite extremity of the scale. The 
two eastern islands, Lanzarote and Fuerteventura, possess more 
of aii African element than the others ; but on the Avholc the 
Canarian Coleopterous fauna does not present a more southern 
aspect than that of Madeira. The large number of purely 
endemic forms seems to indicate the desirability of regarding 
the whole of the two groups of islands as constituting an Atlantic 
province. 
Of the species mentioned in this volume about 540 have been 
first described by the author, and he has also established about 
30 new genera. Many of these are described in scattered 
papers, chiefly in 'the Transactions of the Entomological Society 
of London and in the Annals and Magazine of Natural History; 
but a great number of new species, some of them forming the 
types of new genera, are described in the present volume, and 
will be referred to in their proper places. 
* See, however, on this point a note by Crotch, referred to further on 
(p. 852).
