The Musk Beetle (cerambyx moschatus), plate 22, 

 fig. 9, is of a shining green, exceeds an inch in length, 

 and its presence is often betrayed by its peculiar scent, 

 which somewhat resembles that of a mixture of musk 

 and roses. The antennae are divided into segments, and 

 of such extreme length as to form a distinguishing pecu- 

 liarity of the genera. This species mostly live in the 

 decayed trunks of willows. 



The Oak Beetle (cerambyx heros) is nearly two inches 

 in length, entirely black, except at the posterior portion 

 of the body, where it is dashed with reddish-brown. The 

 larvae, measuring four inches, live in oak wood, where 

 they commit great ravages. 



The Common Sawyer (prionus serrarius) is more 

 than a half inch long ; black, with elytra or wing-covers 

 of reddish-brown ; the antennae are very long ; the body 

 broad; the legs are also brown, and serrated. In the 

 larvae state it lives in the rotten trunks of oaks and 

 pines. 



II. CARNIVOROUS BEETLES. 



Beetles which live on flesh have the body long and 

 flat, the feelers short, maxillae large and pointed; the 

 legs are mostly composed of five joints without barbs, 

 and live on the flesh of living or dead animals. They 

 are divided into three families : Voracious Beetles, Par- 

 asites, and Carrion Beetles,
