My determination of the adurt was confirmed by Dr A. popescu Gori and that of the mined plant by professor M. Hering. r"o lotn -y ri.riin"r*i are rendered here too. I was able to trace in the laboratory the further growth of the species and I shall describe it below. The mineis_in the shape of an oval g"6*irh white stigmatonom (fig. I A) with medial folding. As during ihe first'ero;ih stagesthe larva fo_odsbn the lacunary tissue th-e mine is visinte;;tt;;;h; inner face of the leaves. while gl-owing the larva eats the pati*adic-tissue p to the. hjsher- epidermis avoiiing, f,owever, the veins. fn"s trre mine Decomes vlsrble also on the upper side of the leaf which becomes marmorate. myking, the last. growth stage bf the rarva.
