The above description is based on specimens collected by A. M. 

 Boyce in lemon buds with Aceria sheldoni (Ewing) at Santa Paula, 

 Calif., July 30, 1937. United States National Museum records are 

 Italy, China, Hawaiian Islands, West Indies, and Florida, Louisiana, 

 and California in the United States. Womersley (1942) records it 

 from Australia. It is usually found associated with scale insects or 

 with eriophyid mites on which it preys, and McGregor has reported 

 it predaceous on Tarsonemus haheri Ewing in California. The mite 

 referred to in an article by Boyce and Korsmeier ( Journ. Econ. Ent., 

 vol. 34, No. 6, p. 754, 1942) as Gheletomimus ornatus Berlese is actu- 

 ally Cheletogenes ornatus (Canestrini and Fanzago).

Female. — Small mite, more elongated than Cheletogenes ornatus^ 

 with narrow rostrum. Femur of palpus short, broad, swollen on 

 outer margin, with broadly squamiform dorsal seta and two simple 

 ventral setae, the lateral seta missing; genu with broadly squamiform 

 serrate seta on posterior margin; other palpal setae simple; palpal 

 claw toothed for about two-thirds of its length, with 11 teeth ; outer 

 palpal comb large, with about 20 teeth; inner comb small, about one- 

 half as long as outer, with about same number of teeth. Rostrum 

 long, narrow, covered with a very characteristic shield, which is
