A rare and remarkable coleopterous inseet was taken on a wall 
in the Wells Road, close to Bath, in September last, being a 
valuable addition to our Bath Entomologia. This insect belongs 
to the family of Cerambycide. It is the Cerambyx edilis of 
Linnzus, placed however under a distinct genus by Megerle, 
with the name of Acanthocinus. Stephens has adopted this new 
genus in his “British Entomology,” where the insect stands as 
Acanthocinus edilis.t The specimen captured is a male of unusual 
size and in good condition. It is a species found throughout 
Europe, but rare except in Sweden, where Linneus, in his “‘ Fauna 
Suecica,” speaks of it as being often found in boats, and in the 
trunks of trees that have been decorticated ; such trees being 
used by the peasants in the construction of their houses, and it is 
whilst at work that they frequently find these insects. The 
children there call them ‘‘ Timberman,” answering to “ Carpenter” 
in our language. : 
In this country it is not at all common, but has been met with 
* From stegos a roof or covering.
