ISLAND LIFE. 



[part II. 



59. L. CALEDONiELLA. North Britain (1854). A local variety of the more 



widespread L. corijlifoliella. 



60. L. DUNNiNGiELLA. North of England (1852). A somewhat doubtful 



species. 



61. BuccuLATRix DEMARYELLA. Widely distributed (1848). Eather 



common. 



62. Trifurcula squamatella. South of England (1854). A doubtful 



species. 



63. T. ATRiFRONTELLA. South of England, also in Lancashire (1854). Very 



rare and peculiar. 



64. Nepticula ignobiliella. Widely scattered (1854). On hawthorn, 



not common. 



65. N. POTERii. South of England (1858). Bred from Larvae in Poterium 



sangnisorha. 



66. N. QTJiNQUELLA. South of Euglnnd (1848). On oak-leaves, very local. 



67. N. APiCELLA. Local (1854). Probably confused with allied species on 



the continent. 



68. N. HEADLEYELLA. Local(1854). A rare species. 



Pterophorina. 



69. Agdistis bennettii. East coast (1840). Common on Staiice Umonium. 



We have here a Kst of sixty-nine species, which, according 

 to the best authority, are, in the present state of our know- 

 ledge, pecuKar to Britain. It is a curious fact that only five of 

 these have been described less than twenty years ago ; and as 

 during all that time they have not been recognised on the 

 continent, notwithstanding that good coloured figures exist of 

 almost all of them, it seems highly probable that many of them 

 are really confined to our island. At the same time we must 

 not apply this argument too rigidly, for the very day before my 

 visit to Mr. Stainton he had received a letter from Professor 

 Zeller announcing the discovery on the continent of a species of 

 our last family, Pterophorina, which for more than forty years had 

 been considered to be exclusively British. This insect, Flatyptilia 

 similicladyla {Pteropliorus isodadyhis, Stainton's Manual), had 

 been taken rarely in the extreme north and south of our islands — 

 Teignmouth and Orkney, a fact which seemed somewhat indica- 

 tive of its being a straggler. Again, seven of the species are 

 unique, that is, have only been captured once ; and it may be 

 supposed that, as they are so rare as to have been found only 

 once in England, they may be all equally rare and not yet found 

 on the continent. But this is hardly in accordance with the laws
