The "Pompilidse" of the last edition. Includes rather slender, long- 

 legged solitary wasps with the abdomen united to the thorax by a very 

 short stalk. They are usually velvety black or blue, often with orange 

 bands, wings usually black and kept in constant jerky motion when the 

 insect is moving about. The species prey on spiders and other insects 

 and may be diggers or makers of mud cells under stones, etc. Some are 

 said to be guests in the nests of other diggers.
