On the Structure of the Buccal Cavity, Pharynx and Spermatheca in South American Phlebotomus

Through the kindness of Prof. Mazza, Buenos Aires, Dr. P. A. Buxton, of the London School of Tropical Medicine, and Prof. Brumpt, Paris, I have had the opportunity of examining a collection of sandflies from South America. It appears that, as in the sandflies of the Old World, the structure of the buccal cavity and spermatheca, and to a smaller degree that of the pharynx, affords an easy mean of distinguishing the five species at my disposal.
