DISTRIBUTION AND HOSTS P. loosi is a serious pest of tea in Sri Lanka. It was also reported from tea and citrus in India (Sethi & Swarup, 1971) and from tea, apple, citrus, pear, Convallaria and natural grassland in Japan, with the exception Yamamoto & Kondo, 1972; Nakasono, Yamamoto, Okamoto & Ichinohe, 1974; Ushiyama & Ogaki, 1970). However, specimens from Convallaria from Japan appeared to have a stylet 18 u long as against 15–16 µ in the Ceylonese specimens (authors observations). The conspecificity of at least some of the Japanese populations with the Ceylonese ones could therefore be in doubt.
