 1 a s p i d i s 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, 

 Gymnocladus canadensis, and from this mite on corn.
