In-the present paper, the author gives notes on the following Gracilariid species which have hitherto been unrecorded from Japan. 1. Acrocercops labyrinthica Meyrick Specimens examined : 1♂, Ambo, Yakushima, 25 Oct. 1959 ; 7♂♂ , 7♀♀? , 3-9 Nov. 1959 ; 2♂♂ , 2♀♀ , 15-20 Nov. 1959 (H. Kuroko), bred from the larvae mining in the leaves of Trema orientalis Blume at the end of October. 2. Acrocercops cathedraea Meyrick Specimens examined: 3♂♂, 1♀ , Ambo, Yakushima, 8-10 Dec. 1959 (H. Kuroko), bred from the larvae mining in the leaves of Urena lobata Linn. var. scabriuscula A. Gray at the end of October. 3. Acrocercops caerulea (Meyrick) Specimens examined: 2♂♂, 3♀♀ , Onoaida, Yakushima, 2-10 Dec. 1959 (H. Kuroko), bred from the larvae mining in the leaves of Vigna marina Merrill at the end of October. The specimens bred from Stephania hernandifolia by Fletcher (1933) may probably differ from caerurea. 4. Acrocercops dissotoma Meyric k There are three broods in a year on Mt. Hikosan. The larvae feed in the leaves of Lespedeza cyrtobotrya Miq. or Pueraria lobata Ohwi, from the beginning to the middle of July, from the beginning to the middle of August and from the beginning to the end of September, and the adults appear at the end of July, between the end of August and the middle of September, and at the beginning of June of the following year. It deserves special mention that Mesocoelus philippinensis Muesebeck was bred from the larvae of this species. 5. Leucospilapteryx omissella (Stainton) Specimens examined: 1♂, Tokyo, 1 July 1951; 2♂♂, Mt. IIikosan, 22 & 26 July 1954 ; 1♀ , 11 Aug. 1954 ; 2♂♂ 12 & 15 July 1955 (H. Kuroko), bred from the larvae mining in the leaves of Artemisia princeps Pampan. The larvae occur from the end of May to the end of June, from the end of July to the beginning of August and at the end of September on Mt. Hikosan. 6. Lithocolletis dorinda Meyrick Specimens examined : 1♀ , Onoaida, Yakushima, 1 Nov. 1959 ; 1♂ , 2♀♀ , 30 Nov.-1 Dec. 1959 (H. Kuroko), bred from the larvae mining in the leaves of Desmodium Buergeri Miq. at the end of October.
