locality; it lias, however, been recently (1889) taken 
iu Norfolk, and one specimen was captured a few 
years ago near Romney Marshes. 
Another genus, Tetrops , — of which the single 
species is also common near London, and easily kuown 
by its linear shape, very small size, black head and 
thorax, and yellowish elytra, — is worthy of notice on 
account of each of its eyes being absolutely divided 
into two by the insertion of its antennae. 
The Longicornia are, as a rule, so rare in this country, 
that the young collector will probably be some time 
before he takes more than this insect, one or two 
small species of 6r rammoptera, Gl/ytus arietis, and a 
Rhagium.
