A new species of gregarine and two already-known species of gregarines from Japanese Coccinellidae are described in this paper. Two species of gregarines have been reported until now from three species of Coccinellidae in Japan.0ne is Gregarina katherina Watson from Coccinella bruckii Muls (Recently the name of this host was changed from C.bruckii Muls to C.septempunctata L.)and fromAiolocharia mirabilis Motsulsky reported by H. Tsugawa in 1951.The other Gregarina chilocori Obata from Chilocorus rubidus Hope reported by K.0bata in 1953.The description of these two species are rewritten according to the system which the author proposed in the previous paper. During the spring in 1980 a lot of C.septempunctata L. were collected at the campus of Yamaguchi university and they were heavily infected with G.katherina..Each stage of the life cycle of G.katherina Watson is shown in the photograph. A new member of gregarine is found in the intestine of Epilachna pustulosa Kono. E. pustulosa is a comparatively large ladybird and lives on the plants genus Cirsium.Ten percents of E.pustulosa collected at Nopporo in Hokkaido during the summer of 1971 and five percents of E.pustulosa collected at Aratani in Yamaguchi City during the summer of 1979 were infected with this gregarine. Epilachna vigitioctomaculata Motshulsky which lives on Solanum tuberosum L.Collected in Hokkaido during the summer of 1971 and 1979 were examined on the parasitism of gregarines but no parasite was observed at both times.
