CERAMBYX. 
73 
Cerambyx moschatus, when dried and reduced to 
powder, and made use of as a vesicatory, in the 
manner of the officinal Cantharides, produces a 
similar effect, and in as short a space of time *. 
Ceramby.v coriariiis of Linnaeus is also one of 
the larger European species, measuring near an 
inch and half in length, and is of a broadish shape, 
with thick, serrated antennae of moderate length: 
the tliorax is armed on each side with three sharp 
spines or denticulations, and the whole insect is of 
a deep brown colour. It proceeds from a large 
yellowish white larva, with a chesnut-coloured 
head, which resides in the hollows of decayed 
trees, and changes into a chrysalis of similar 
colour. 
Ceramhyx cediiis is one of the smaller or middle- 
sized species. It is a native of many parts of 
Europe, and is found in our own country, though 
not a very common insect. It is of a grey colour, 
with two or three obscure transverse brown bands, 
and the thorax is marked by four yellow spots: it 
is remarkable for the excessive length of its an- 
tennae, which, in the male especially, are five or 
six times that of the body. It is found in old de- 
cayed timber, and in the trunks of trees.
