Prionus coriarius. " It is a fact generally observed, 

 that insects multiply extremely in peculiar habitats. 

 Providence having assigned to each animal its pecu- 

 liar offices and instincts, seems to have ordained that 

 in situations where the agency of numbers is re- 

 quired, the increase of the tribe should keep pace 

 with the increasing necessity for its existence. In 

 the northern regions, where vegetation is scant, and 

 where the evils arising from fallen timber is scarcely 

 felt, the species of Cerambicidse, or Wood-dispersers, 

 (to which tribe the Prionus coriarius is referred,) are 

 few, and the individuals of each species rarely met 

 with. In the temperate zone, where vegetation is 

 more abundant, the insects of this class increase in 

 proportion, and in tropical climates, where vegeta- 

 tion is luxuriant, and where tornado and storm con- 

 cur with other causes to desolate large tracts of 

 country, and fell the trees of the forest, there, to 

 prevent the evils which the progress of vegetation 

 would sustain from the fallen trees, the benignity of 

 Providence has caused the Cerambicidae to abound: 

 myriads of large and various species unite to remove 

 the evil. The enormous trees of the tropics vanish^
