author prepared the fleas for study, made the identifications, wrote 

 the descriptions of new species, and prepared drafts of the figures. 

 The writers are deeply appreciative of the aid given by Maj . Robert 

 Traub, of the Army Medical Center, Washington, D. C, and more 

 especially of the help given by Dr. Frank M. Prince, of the Plague 

 Suppressive Measures Laboratory, San Francisco, Calif. With 

 exception of Meringis dipodomys Kohls (1938), Dr. Prince 

 checked the identifications of representatives of all species recorded 

 in the present paper. The specific determination of M. dipodomys 

 was made by Major Traub. 



During the course of this study two new species of fleas were 

 discovered. These are described herein. In addition, nine species 

 are reported for the first time from the State of New Mexico, and 

 numerous other species are reported for the first time from the 

 vicinity of Albuquerque. The present paper brings to a total of 

 34 the species and subspecies of fleas known from the State. With 

 few exceptions the classification and nomenclature used here fol- 

 low so closely the work of Hubbard (1947) that synonymies have 

 been for the most part omitted. The species in the body of the 

 present paper are systematically arranged in the order given by 

 Hubbard. 



The specimens upon which this study is based have been dis- 

 tributed to interested institutions, including the United States Na- 

 tional Museum, the Texas State Department of Public Health, the 

 Army Medical Center in Washington, the Plague Suppressive 

 Measures Laboratory in San Francisco, and the Microbiological 

 Institute of the Rocky Mountain Laboratory of the United States 

 Public Health Service, in Hamilton, Mont. The holotypes and allo- 

 types of new species have been deposited in the United States 

 National Museum.
