Xhe genus Leptura, greatly allied to that of 
Cerambyx, contains several species of considerable 
beauty, among which may be reckoned the Lep- 
tiira arciiata, of a black colour, with the wing- 
sheaths marked by transverse, yellow, lunated 
bands pointing backwards: it is found in woods 
during the summer months, and generally mea- 
sures about three quarters of an inch in length. 
Leptiira arietis is of nearly similar appearance, 
but the second band of the wing-sheaths is di- 
rected forwards: both the above insects are by 
some referred to the genus Cerambyx. 
Leptiira aquatica is so named from its being 
particularly found in the neiglibourhood of waters, 
frequenting the plants which grow near the water’s 
edge. It is about half an inch in length, and of a 
golden green colour, sometimes varying into cop- 
per-colour, purple, or blue, and is distinguished 
by having a tooth or process on the thighs of the 
hind-legs.
