Note BA — NOTICE OF INSECTS WHICH HAVE BEEN ERRONEOUSLY REFERRED IN RECENT TIMES TO BUTTERFLIES.
Reading edition
Perhaps Mr. Butler is not altogether to blame in confounding Aix in Provence with Aix-la-Chapelle; at any rate the mistake had been made previously by the translator of Heer’s paper in the Quarterly Journal of the Geological Society of London, VI, 72; the error is corrected by Mr. Butler at the end of his volume.
