60 THE ENTOMOLOGIST. 



time and zeal to the subject which Mr, Wollaston has done, 

 and he would inevitably overlook two-thirds of our species, 

 and amongst the omissions would be Saperda Carcharias, 

 S. scalaris, Oberca ocnlata, Lamia tcxtor, &c. ; in a word 

 nearly all our more conspicuous species. Aromia moschata, 

 Clytus Arietis, C mysticus, Rhagium Inquisitor, R. bifascia- 

 tum, 'J oxotus meridianus, Strangalia armata, and one or two 

 GrammopteriB, would in all probability complete the list, and 

 furnish that stranger with materials for profoundly philoso- 

 phical, yet inaccurate, deductions on the causes which de- 

 prived us of the long-horns, — deductions which a cursory 

 glance at the collections of a Wollastou, a Power, a Rye or 

 a Waterhouse might possibly dissipate. Had the Canaries 

 the good fortune to possess an indigenous Wollaston or a 

 resident Power, those si^ecks in the Atlantic might possibly 

 tell a different tale. With regard to the Hydradephaga the 

 case is somewhat different: there is no doubt that every pool 

 and every rill has been carefully swept, and lias yielded up 

 its inhabitants to the energetic skill of the explorers; I use 

 the plural advisedly, because Dr. Crotch's labours have con- 

 tributed largely to the result. 



These are mere thoughts which occur in turning the pages 

 of this most interesting volume, which, as a contribution to 

 Science, is one of the most careful and valuable I have ever 

 perused : long may the kind-hearted and indefatigable author 

 live to prosecute his labours ! It is impossible for me to do 

 more than invite attention to volumes (I allude to Mr. Wol- 

 laston's other works as much as to this) which, in profound 

 research and careful elaboration, are unapproached by any- 

 thing that this country has hitherto produced. I cannot, 

 however, resist the temptation to append the following para- 

 graph : — 



" Of the genera as yet detected at the Canaries, the largest 

 (and by far the most characteristic) is Laparocerus [Curculio- 

 nidaj], of which no less than thirty-five exponents have 

 already been brought to light (and there are probably many yet 

 to be found). The next is Homalota; but as a considerable 

 proportion of the minute staphylinids which compose that 

 immense group are eminently liable to accidental diffusion 

 (through indirect human agencies) over the civilized world, I 

 lay but little stress upon this fact. But the third in order,
