THE INSECTS, OF NEW JERSEY. 68 1 



Family CRABRONIDyE. 



Rather small diggers, with an unusually large quadrate head. They are 

 not uniform in habit, but many live in pithy stems, burrow in dead wood 

 or make use of an old cavity. They store their cells with flies, plant-lice, 

 other insects or even spiders.
