ClJRCULIONIDiE. 
06. *Catiiormiocerus maritimus (Rye). 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^:. 
70. Thyamis agilts (Rye). South of England ; many specimens. 
„ disting (JENDA (Rye). South of England ; many specimens. 
71. *Psylliodes luridipennis (Kutschera). Lundy Island. A very 
curious form, not uncommon in this small island, to which it appears 
to be confined. 
C/OCCINELLIDiE. 
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 which 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 whose names are marked 
with 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 which have occurred 
either rarely or in some abundance. Dividing the probabty 
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
