1. Two different types of tumors were observed in the mature third instar larvae of v tu and st tu strains of D. melanogaster; one was the melanotic mass floating in the body fluid, and the other was the melanotic tissue inserted in tissues of the fat body, the hypoderm, the trachea, and the intestine. 2. In the former tumors, no further growth was observed when they were cultured in the synthetic medium, whereas the latter tumors showeds the marked melanotic growth in the surrouuding tissue. 3. When the cephalic complexes involving the ring glands of the mature third instar larvae were cultured together with the tumor tissues, the melanotic growth of tumor tissues was markedly inhibited. This phenomenon secms to be caused by the metamorphic hormone secreted from the ring gland.
