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.r coriarius 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 thorax 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. 



Cerambyx cedilis 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.
