%X The present studies on the alimentary canal of the last instar Deudorix isocrates (Fab.) larva describe the anatomical and histological details which have not been reported earlier. The straight alimentary canal is divisible into foregut: buccal cavity, pharynx, esophagus, and crop; midgut and hindgut: pylorus, ileum, colon, and rectum. The wall of the buccal cavity, pharynx, and esophagus is composed of cuboidal epithelium which is produced into six longitudinal folds. The intima of the posterior pharynx is characteristic as it shows longitudinal overlapping ridges and backwardly directed bristles. The crop has thin intima and numerously folded squamous epithelium. Musculature is very thin in this region. The stomodaeal valve is derived from the foregut with characteristic histological features. The anterior and posterior interstitial rings are composed of small columnar epithelium. The midgut wall is composed of simple columnar epithelium with scattered goblet cells and individually distributed regenerative cells, the luminal side has the peritrophic membrane, and the Midgut musculature is thin and is composed of an inner thin circular muscle layer and outer longitudinal muscle bundles. The hindgut epithelium is cuboidal at the pylorus colon and rectum while at the ileum it is squamous type. The intima of the hindgut is relatively thin as compared to that of the foregut but it produces patches of spines at the posterior pylorus. The rectum forms the cryptonephredial system.
