from larvae feeding upon red spiders, Tetranychus myt i- 
Pispudis and. T. sexmaculatus, infesting lemon leaves 
and fruit at Chula Vista, Cal. This species appears to be a rather 
common enemy of the red spider, since lots received through the 
courtesy of Doctor Howard show that this or a very closely allied 
form was reared from red spider on the Kentucky coffee tree,
