PLATE XX. Fig. 4. 
Curculio populi, Linn. Degeer — Attelabus populi, Fair . 
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. 
RHYNCHITES PUBESCENS. 
PLATE XX. Fig. 5. 
Attelabus pubescens, Fabr. 
The body is rather more elongate in proportion 
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. 
The legs are the same colour as the body, but the 
tarsi are black. Length three lines. It inhabits 
France. Germany, and England.
