3 A buprestid larva taken from the root of Copiapoa humilis at Paposo, Chile, 31 Jan., 1952, was not determinable, even to genus, at the national collection at Washington, D.C. Another specimen, taken from the stem of Copiapoa taltalensis, from which it emerged at the botanical garden (Berkeley), was determined as "near Poecilonota sp." This genus, however, is not previously recorded from Chile and it seems more likely that the latter specimen is related to Ectinogonia, several specimens of which I collected in the same area. The larval stages of these genera are apparently little known. I was not able to definitely link larval and mature forms of any Buprestidae taken in this area.
