113 THE ENTOMOLOGIST. 



enunciated by Prof. Edward Forbes, whose loss we shall always 

 have cause to regret ; further comment would therefore be 

 premature ; but 1 cannot refrain from adding that Mr, Wol- 

 laston's ' Catalogue,' besides its undoubted scientific value, 

 does as much credit to his field labours as to his scrupulous 

 accuracy. It was, to us, a constant source of amazement, 

 not that he should have failed to find species which we sub- 

 sequently obtained, but that he should have accomplished so 

 much, and that without the aid of graduated wire sieves, 

 which, in our case, economised so much time and labour. 

 The relative distribution of Coleoptera among the Islands 

 may be stated as follows, viz., Lanzarote 277, Fuerteventura 

 261, Grand Canary 335, Teneriffe 554, Gomera 408, Palraa 

 254, and Hierro 210 ; but it must be observed that the num- 

 bers assigned, especially for Grand Canary, Palma and Hierro 

 are probably far too low. The annexed table gives, in the 

 first column, the number of Madeiran species in each section ; 

 in the second, the arithmetical proportion which might be 

 expected in the Canaries ; and in the third, the actual num- 

 bers found. And I believe that if the sections were better 

 chosen, especially with regard to philhydrous representatives 

 of terrestial species, the parallelism would be even more 

 complete : —
