In my previous paper "Male genitalia of the species of Depressaria Haworth s.l. (Lepidoptera, Oecophoridae) occurring in the Netherlands" (1964, Zool. Meded., 39: 391-408) the species Agonopterix scopariella (Heinemann) has been omitted from the key to the species. On p. 395, the relevant paragraph should read: 3. Aedeagus long and slender, with a long basal prominence, reaching towards the middle. Gnathos rather widely-ovate. . A. angelicella — Aedeagus short and stout, with a short prominence. Gnathos elongateconical ............A. scopariella One species should be added to the Dutch list, viz. Agonopterix applana (Fabricius). In the present note a drawing of the male genitalia of this species is presented together with the following short description. Cuiller not reaching to the costa, top bending outwards, sharply pointed. Gnathos elongate-ovate. Aedeagus index =1:7. The relevant addition to the key to the species in my former paper (p. 395) is as follows: 8. Cuiller stout, top square.........A. costosa — Cuiller slender, top sharply pointed......A. applana — Cuiller with rounded top...........9
