CuRCULIONIDiE. 



66. ^Cathormiocerus maritimus (Rj^e). A few specimens on our south 



coast. A curious genus, only found elsewhere on the coasts of the 

 Mediterranean ! 



67. ^'Ceuthorhynchus contractus, var. pallipes (Crotch). Lundy Island ; 



several specimens. A curious variety only known from this island. 



68. "^"LiosoMUS TROGLODYTES (Rye). A very queer form. Two or three 



specimens. South of England. 



69. "^"Apion ryei (Blackburn). Shetland Islands. Several specimens. 



Halticid^. 



To. Thyamis agilts (Rye). South of England ; many specimens. 



„ DiSTiNGtJENDA (Rye). South of England ; many specimens. 



71. "^PsYLLiODES LURiDiPENNis (Kutschcra). Luudy Island. A very 



curious form, not uncommon in this small island, to which it appears 

 to be confined. 



COCCINELLID^. 



72. ScYMNUS LiviDUS (Bald). Northumberland. A doubtful species. 



Of the seventy-two species of beetles in the preceding list, a 

 considerable number no doubt owe their presence there to the 

 fact that they have not yet been discovered or recognised on 

 the continent. This is almost certainly the case with many of 

 those which have been separated from other species by very 

 minute and obscure characters, and especially with the exces- 

 sively minute Trichopterygidse described by Mr. Matthews. 

 There are others, however, to wdiich this mode of getting rid of 

 them will not apply, as they are so marked as to be at once 

 recognised by any competent entomologist, and often so plentiful 

 that they can be easily obtained when searched for. Of this 

 class are the twenty-three species Avhose names are marked 

 wdfch an asterisk (*), being those which, in Mr. Rye's opinion, 

 are most likely to be peculiar to the localities where they are 

 found if any are, — but of this he is still somewhat sceptical. 

 Six of these are unique, leaving seventeen w^hich have occurred 

 either rarely or in some abundance. Dividing the probably 

 peculiar species according to locality, we find that the South of 

 England has produced 9, North of England 2, Scotland 6, 

 Ireland 1, Shetland Islands 1, and Lundy Island 2. These
