664 REPORT OF NEW JERSEY STATE MUSEUM. 



Family MUTILLID^E. 



The females resemble ants in general shape, in being often wingless 

 and in being found running about among the grass in sandy spots. They 

 are densely clothed with hair, however, and are contrastingly colored with 

 black, yellow and orange, the name "velvet ants" being applied from 

 their clothing. They differ from the ants in lacking the nodes at the 

 base of the abdomen, and from our local species further, in having a very 

 long and very hot sting. The males are winged and occur on flowers. 

 In habit the species are diggers, and while some are known to store food 

 for their larvee, others seem to be parasitic or guests in the nests and 

 cells of bees and other wasps.
