A HE genus Leptura, greatly allied to that of 

 Cerambyx, contains several species of considerable 

 beauty, among which may be reckoned the Lep- 

 tura arcuata, 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. 



Leptura 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. 



Leptura aquatica is so named from its being 

 particularly found in the neighbourhood 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.
