Discussion: These are long-legged, fast moving mites, predaceous on 

 other mites and many small insects. They are to be found on plants, 

 tree leaves, branches, and grass. Although they are not usually abun- 

 dant, they occasionally may be found in great numbers. Anystis agilis 

 (Banks) is described from the United States and Walzia antiguensis 

 (Stoll), a Venezuelan species, has been found in Florida. 



The larval, nymphal, and adult stages are similar; two nymphal 

 stages are known. The mites apparently have the power of spinning 

 and the young can enclose themselves in a cocoon (nymphochrysalis 

 or teleiochrysalis). Banks has found freshly molted specimens encased 

 in little silken white cocoons.
