violet blue, having the antenne and the legs black, and the elytra 
of a splendid golden green, with longitudinal streaks. According 
to Réaumur, the larva of the Calosoma often chooses a home in 
the nest of the Procession-Moth Caterpillar (Bombyx processionea), 
on oak trees, and it very soon rids the tree which is infested by 
them. 
The Calosoma auropunctata is found in the south of France. 
Its larva (Fig. 506) devours snails, and establishes itself in their 
shells. These larvee have been known to fill themselves so full

they are sometimes devoured by those of their own species. 
A smaller kind, the Calosoma inquisitor, is very frequently to 
be met with in woods. Fig. 507 presents Calosoma sycophanta 
pursuing a Bombardier (Brachinus explodens), which squirts out a 
vapour of pungent odour. 
In the countries of the south-east of Europe and in Asia 
Minor, one finds enormous Carabidae, the Procrustes and the Pro- 
ceri, which attain nearly two inches in length, and whose in- 
teguments resemble very rough shagreen. One species alone is 
met with in France, the Procrustes coriaceus (Fig. 508). In 
Austria is found the Procerus gigas (Fig. 509).
