were obliged to cut down in the Bois de Vincennes, twenty 
thousand feet of oak trees, aged from thirty to forty years, com- 
pletely ruined by the ravages of the Scolytus, whose larva is here 
represented (Fig. 558). The genus Yomicus, hairy, and of a 
tawny colour, are a terrible plague to pine forests. In 1783, in 
the Forest of Hartz, a million and a half of trees were lost by 
these insects. Often have the priests implored, in the churches, 
the Divine clemency, to put an end to the devastations made by 
them. 
We arrive at the tribe of the Longicornes, which contains 
beautiful insects, of elegant shape and varied colours, sometimes 
also of rather large dimensions. 
The genus Cerambyx has the antenne very long; they exceed 
in some of the species two or three times the length of the body. 
The larve are large whitish worms, which live in the wood of trees,

the adult insects frequenting flowers, rotten trees, &c. In the 
month of June, on the Continent, one meets on the oaks with the 
Great Capicorne (Cerambyx heros, Fig. 559), of a dark brown, 
whose larva (Fig. 560) scoops out its galleries in the interior of 
the tree, and often occasions much damage.
