In this paper the author wishes to rearrange the description of Gregarina korogi and to report on the moprhological diagnosis of Leidyana erratica (Crawley) Watson which is found from the same host. The host Gryllus yemma Ohomachi et Matsuura (G. mitratus Burmeister) is the most common cricket distributed in the western district of Japan. At the beginning of the autumn, 1972, the author collected a lot of individuals of this cricket in the bush at Era in Yamaguchi City and found most of them were infected with two different species of gregarines in their digestive tracts, gastric caeca and stomachs. From September to November he carried on his investigations on these gregarines. One of them is easily identified with Gregarina korogi H. Hoshide, but the other is undoubtedly considered to belong to the genus Leidyana. H. Hoshide (4,5) had already described several gregarines from the Orthoptera of Japan as shown on the list of the present author's previous paper but H. Hoshide had made no mention of the species of the genus Leidyana from Orthoptera. Most materials used in this study were collected in or in the suburbs of Yamaguchi City but some of them were caught at Iwakuni or Obatake in Yamaguchi Prefecture.The material collected at each place was parasitized with these two species of gregarines mentioned above. In September 1972 the author made a careful examination about 110 hosts captured at Era and 85 of them were infected with Gregarina korogi and 42 of them with Leidyana erratica. Among them 15 crickets were parasitized with the two species of gregarines, Gregarina and Leidyana.
