The taxonomy of flies of the genus , and particularly of the important and widespread species or forms of the “ complex,” has received considerable attention in many parts of the world. In spite of this, the status of such forms as Macq., F., and Patton is not at all clear. Consequently, it is worthy of note that the work now being carried on at the laboratory of the U. S. Naval Medical Research Unit (NAMRU-3) in Cairo, Egypt, and the opportunities there for coordinated field and laboratory studies of several of the forms and their interactions, offer real hope for securing significant information on the problem.

During a six weeks' assignment at NAMRU-3 in June and July, 1950, as consultant on taxonomic problems in the genus , I determined that at least eleven species and subspecies of occur in Lower Egypt, as follows: Macq., (tentatively regarded as a subspecies), Wied., Stein, Wied., Fallén, Wied., Meigen, Portsch., Mall., and Loew.
