General Observations. 



Linnaeus has divided this genus into the fol- 

 lowing sections : 



1. Thorax armed on each side with move- 

 able spines. 

 £. Thorax margined, and sides spiny. 



3. Thorax round, armed with fixed spines. 



4. Thorax subcylindrical and without spines. 



5. Thorax roundish, without spines, and of 

 a depressed globular shape. 



The insects of this genus, which are very 

 numerous, are easily known by the figure and 

 position of their antennas, and the number of 

 articulations of which the tarsi are composed. 

 Many of them are particularly distinguished
