The hindgut epithelium of the termite (worker) was examined with an electron microscope. A characteristic localization of mitochondria similar to that found in the active transport system of excretory organs was observed in the apical cytoplasm of the epithelium of rectal papilla and paunch, but no such localization of mitochondria was observed in the basal part of the paunch epithelium. Cuticle intima in both of the epithelia differed from each other; in the central part of the paunch cell it was thicker and composed of a homogeneous material which was positive to a silver-methenamine reaction. When the termite was administered a glucose solution instead of cellulose as food through the stomodeal after 24hr starvation, a vacant space was observed between the cuticle intima and the apex of the paunch epithelium. These morphological characteristics of the paunch epithelium are regarded as an indication of site of the nutrient absorption in the hindgut.
