The probing punctures by N. cincticepts on the rice plant leaf were found abundantly in the area adjacent to stomata on the both of abaxial and adaxial sides of the midde leaf veins, although some of them were found also on the moter cells and small leaf veins. The mouth parts inserted into the host tissue in situ were abtained by killing insects with high voltage shock, and they were fixed and sectioned for histological study. When the stylet is inserted into the plant tissues, the salivary sheath is formed with saliva secreted from the tip of the stylet. The salivary sheath having the form of ramifying root was observed frequently. Sometimes the stylets curved, but only to the right and left directions. The stylets or stylet track usually reached the phloem or xylem, although they terminated in the mesophyll or parenchyma in the leaf tissue. In average, 70.3 per cent of the salivary sheaths left by N. cincticeps within the leaf sheaths of rice plant reached the vascular bundles, while only 29.7 per cent terminated in the mesophyll or parenchyma. From these results, it is considered that the feeding habit of the leafhopper belongs to the vasular bundle type.
