In this well-known species the body is smooth 

 and shining, of a golden-green or bluish tint on the 

 upper side, and dark violet colour beneath ; the an- 

 tennae and tarsi black. The elytra are rather irre- 

 gularly punctured. In one of the sexes there is an 

 acute spine on each side of the thorax, projecting 

 forwards. The ordinary length of the insect is nearly 

 three lines. It is found on poplar and birch trees, 

 in England and on the Continent of Europe.

 to its breadth than in the preceding species. The 

 whole body is of a deep violet colour, and clothed 

 with rather long hairs. The snout is shorter than 

 the thorax, and, together with the antennae, black. 

 The elytra are marked with regular punctured lines.
