THE CERBERODON.

follows. It is rather remarkable, by the way, that the insects 

 which are popularly called Locusts do not belong to this family. 



The formidable-looking insect which is called Cerberodon viridis 

 is quite as formidable as it appears to be, and fully deserves its 

 generic name, wdnch will be presently explained. It is a native 

 of Brazil. As the specific name imports, the colour of the insect 

 is green. 



It is chiefly remarkable for two points, the fl'rst of whicli is 

 the structure of the legs. All the limbs are furnished with thorn- 

 like spikes, but the front pair are most poM'erl'ully armed in this 



respect, the tibia having ten long curved spikes, five on each side, 

 arranged as seen in the illustration. The thigh is also armed, 

 but the spikes are not nearly so long and so Y»^'werful as those 

 of the tibia. 



The second characteristic lies in the jaws, which are really 

 gigantic in proportion to the rest of the body. They are long, 

 stout, curved, and furnished with teeth on the inner surface. In 

 this genus, the left jaw is much larger than the right, and is 

 prolonged into a sickle-like point. The name Cerherodon refers 

 to this peculiarity. It is formed from two Greek words, one signi- 

 fying "a tooth," and the oilier Cerberus, tlie three-headed dog of
