ally ; aedeagus with one large cornutus tapering to a sharp point (Fig. 1 : A, D). The nearly related geminella Frey has a more appressed subscaphium, valvae more narrow, its central tip dominant laterally, costa arched (Fig. 1. : B, E). Poterii Stt. has also an appressed subscaphium, valva with a very elongated central tip, serrated anteriorly (Fig. 1 : C). The egg-shell is to be found always glued on the rhachis of the underside of the leaf. The mine of the new species is long, narrow at the beginning, strongly broadening later, serpentine. Owing to the overlapping of the galleries, it beFig. 1. Male genital organ, ventrally, of A: Nepticula elisabethella sp. n., B : N. geminella Frey, C : N. poterii Stt.

The margins of the galleries are not parallel. The excrement builds originally a narrow, central line, interrupted at uneven intervals, dispersing later into dense, smaller or bigger, grains. The excrement fills up about 1

Nepticula utensis Weber var. biol. hexapetalae var. nov. On the 28 June 1956, I collected some Nepticula thuringiaca Petry larvae in the leaves of Fill pendula hexapetala, on the hill Sashegy, in Budapest. In the collected material, I found six larvae which were green instead of yellow, so they manifestly belonged to a new species. Three imagos emerged between 22—26 July 1956. The animals are remarkably small (2,5— 4 mm), but the description of N. utensis Weber absolutely agrees with my specimens, and also
