Intracellular inclusions in the epithelial cells of the midgut of Piesma cinereum (Hemiptera) are described. Three types of inclusions have been observed in both viruliferous and "virus-free" insects. Two of them, alpha and beta, are free in the cytoplasm and are of two different basic configurations: one exhibits bilateral symmetry, the other a fivefold radial symmetry. Still another type of inclusion is contained in membrane-bounded bodies and consists of elongate, irregularly shaped crystals. A description of the structure of the inclusions is given and their nature and significance are discussed.
