The ultrastructure of the eugregarine Leidyana ephestiae, parasitic in the larval gut of the flour moth, Ephestia kuehniella, is described. Guts of experimentally infected larvae of E. kuehniella were fixed and sectioned for electron microscope studies of young and mature trophozoites. Young unsegmented trophozoites were small, oval to ovoid, and possessed a simple, globular epimerite. The plasma membrane covering the epimerite region was continuous with the plasma membrane of the protodeutomerite and was in close contact with that of the host cell. Three cortical membranes covered the protodeutomerite region. Folding of the protodeutomeritic epicyte occurred after about two days of development of the gregarine. After three to four days the body of the trophozoite became differentiated into three segments. A septum was visible between protomerite and deutomerite, but there was nothing similar to this structure between epimerite and protomerite. Fully developed trophozoites showed a large ovoid epimerite containing many mitochondria and vesicles. The epimerite was situated on a short neck filled with fibrils. The cytoplasm of protomerite and deutomerite was rich in amylopectin granules and electron-dense bodies.
