 end and shorter than the body ; eyes large ; abdomen very

The larvae of the insects of this genus are very carnivorous. They lodge in holes 

 in the sand completely concealed, except the long moveable horns or forceps with 

 which they seize the unfortunate insect that comes in their way. They likewise, it 

 is said, when an insect is beyond the reach of seizure, throw up the sand from the 

 bottom, which loosens that on the sides of the hole, and the prey tumbles into their 

 jaws.
