 Although I have good reason for suspecting that a small number 

 of even the 179 species recorded by MM. Webb and Berthelot were 

 (as just stated) brought from Madeira, whilst others (as, for instance, 

 the Erodkis europceus, the Akls acuminata, and perhaps also the 

 Tentyria interrupta) were accidental importations from the coast of 

 Africa [on which subject vide my remarks at pages 438 and 469] ; 

 I have nevertheless alluded to them briefly in foot-notes (in their 

 proper positions), though without further evidence I could not admit 

 them into the body of this volume. There are three, however, which 

 I believe I have passed over in toted silence, — namely, the Cicindela 

 nilotica, Dej., the Mononyx varieyatus, Br., and the Colaspis har- 

 bara, Fab. It is certainly possible that a Cicindela may exist in 

 some of the sandy regions of Lanzarote, Fuerteventura, or Grand 

 Canarj' ; yet the singular absence, so far as my own observations are 

 concerned, of that -wddely spread genus both at the Madeiras and 

 Canaries inclines me to look with unbounded suspicion on its sup- 

 posed occurrence in these islands ; and I shall at aU events require 

 stronger evidence than that supplied by MM. Webb and Berthelot, 

 who give lis no vestige of infoi'mation about it, before I acknowledge 

 it as Canarian. The Mononyx varieyatus may perhaps be a small 

 Curculionid from some portion of the Oroup ; but I could get no 

 sight of it in Paris ; and as no genus has ever been enunciated (so 

 far as I am aware) under the title of Mononyx, it is impossible even 

 to guess at its affinities (so that no position coidd be assigned to it in 

 this Catalogue). If, however. M. Brulle intended himself to establish 

 the group, there and then, ivitJwut a diagnosis (which is the only 

 solution that occurs to me), he has at least chosen a most unfor- 

 tunate name — for the insect figured has decidedly two claws. The 

 Colaspis harbara is a north-African form ; and although, in like 

 manner, it too may be Canarian, I cannot possibly treat it as such — 

 without a single published remark either as to its identification or 

 habitat, and with the well-founded suspicion (above alhided to) that 

 a certain proportion of MM. Webl) and Bcrthelot's recorded species
