THE MUSK BEETLE, OR GOAT CHAFFER. 
(Cerambyx mosehatus, or Aromia moschata.) 
This is one of the longicorn beetles. It is a very beau- 
tiful insect, of a glossy bluish-green colour, with a cast 
of shining gold ; the under part of the body is bluish. 
It is about an inch and a half in length, and is elongated 
in form, its breadth being small in proportion to its

wings, and three smaller towards the head. The cases 
of the wings are oblong, and somewhat in the shape of a 
lance, with three ribs a little raised, and running length- 
wise. The feelers are as long as the body, composed 
of many joints, which grow smaller near the ends. 
This Beetle is very common in the south of England, 
and is chiefly to be found on old pollard willows. It
