Little is known about the parasitic mites of the Far East, espe- 

 cially of the Philippines. Only one species, Haemolaelaps bibbyi 

 Strandtmann and Hunt (1950), has been reported from this area. 



This preliminary study, which considers 17 species, is based upon 

 material collected by the Chicago Natural History Museum Philip- 

 pine Zoological Expedition (1946-^7). Descriptions and illustrations 

 of all species are presented. The classification adopted in this study 

 is that of Strandtmann and Wharton (1958). The holotypes and 

 paratypes of the new species described, unless otherwise stated, are 

 deposited in Chicago Natural History Museum. 



This study was conducted in the Entomology Research Division, 

 United States Department of Agriculture, Washington, D.C., as a 

 part of the training program sponsored by the International Coop- 

 eration Administration (United States Government). I am grateful 

 to Dr. E, W. Baker, of the Entomology Research Division, for the 

 opportunity to study specimens lent to him from the Chicago Natural 

 History Museum collection, and for his taxonomic advice and valu- 

 able suggestions concerning the manuscript.
