1756 Insects. 



ryphus decorus and tibialis, Cercyon obsoletum, Latridius augusti- 

 collis, Cryptophagus scutellatus, Geotrupes laevis, Aphodius scrofa, 

 Oxyomus caesus, Selatisomus aeneus, Throscus dermestoides, Cyphon 

 Pini (Curtis), Cossonus Tardii, Hypera dissimilis, Sitona cambrica, 

 Cleonus nebulosus, Apion subulatum, Spbaeriestes ater, Leptura auru- 

 lenta, Chrysomela haemoptera, Oncomera melanura, Oxytelus depres- 

 sus, &c, not one of which I have myself discovered on the opposite 

 coast, and only four of which are recorded by Mr. Dillwyn in his ela- 

 borate and copious ' Catalogue of the Coleoptera of the Neighbour- 

 hood of Swansea.' 



'It will thus be perceived, from the previous remarks, how great a 

 want of similarity the Coleoptera of Lundy Island displays to the spe- 

 cies observable on the opposite and nearest shore, and the peculiar 

 and striking resemblance which they bear to those abundant on the 

 more distant coast of Wales. Out of 153 species which I have my- 

 self captured within the small and barren compass of Lundy Island, I 

 have ascertained 109 to inhabit for certain the coast of Wales; while, 

 from the common and universally distributed nature of the remaining 

 44, 1 have reason to believe that the whole 153 would, if properly 

 searched for, be found there in profusion. The above observations 

 will show how far different is the state of things along the northern 

 shores of Devonshire and Cornwall, which, although separated from 

 the land by so narrow a space, and, although Lundy is itself a portion, 

 both naturally and artificially, of the county of Devon, have neverthe- 

 less a Coleopterous Fauna utterly dissimilar, and, comparatively 

 speaking, peculiar to themselves. I attempt not to account for this 

 singular fact ; but it is certainly a very remarkable one, and, inas- 

 much as it may bear strongly on the general question of geographical 

 distribution, it is certainly worth recording. 



Out of the 121 species, the result of my visit to the island in 1845, 

 I subjoin a list of the 88 already referred to, as being distinct from 

 those formerly recorded in the * Zoologist } (Zool. 899), and captured 

 during my first trip in 1844.
