PROCEEDINGS OF THE Entomological Society of Washington VOL. 52 JUNE. 1950 No. 3 NOTES ON INDO-MALAYAN FLEAS, WITH DESCRIPTIONS OF NEW SPECIES! -' (Siphonaptera) By Robert Tkaub, Major, MSC, Department of Faraaitology, Arnur Medical Department, Besearch and Graduate School, Washinc/ton, D. C. During recent field studies in Malaya on the epidemiology, prevention and treatment of scrub typhus, conducted by the U. S. Army Scrub Typhus Research Unit,^ it was possible for me to collect a series of fleas which emphasizes how little is known about potentially medically important ectoparasites in the Indo-Malayan area. Included were a new species, a new subspecies, and five little-known species, some of which have never been fully described or figured heretofore. A new genus is proposed for one of these species. All of these were col-lected on a four-day trip to the hills. Descriptions of a new species collected in North Burma during the recent war and of a new subspecies collected by the National Geographic-Smithsonian Institution-Yale University Expedition to Nepal are also included in the present paper."^ ^Published under the auspices of The Surgeon General, U.
