from thirty to forty years, completely ruined by the ravages of 

 the Scolytus, whose larva is here represented (Fig. 560). The genus 

 Tomicus, hairy, and of a tawny colour, is a terrible plague to pine 

 forests. In 1783, in the Forest of Hartz, 1,500,000 trees were 

 destroyed 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 Longkorns, which contains beautiful

insects, of elegant shape and varied colours, sometimes also of rathei 

 large dimensions. 



The genus C>/'^;;/^^'^ has the antennae very long; they exceed in 

 some of the species two or three times the length of the body. The 

 larvae are large whitish worms, which live in the wood of trees, the 

 Sbdult insects frequenting flowers, rotten trees, &c. In the month of 

 June, on the Continent, one meets on the oaks with the Great 

 C2i^ncom {Cerambyx heros, Fig. 561), of a dark brown, whose larva 

 (Fig. 562) scoops out its galleries in the interior of the tree, and 

 Qfteti occasions much damage.
