THB CURRANT SPHYNX-MOTH, trees, particularly to the black currant, which soon indicates the presence of the insect by the withering of the foliage and branches. Towards the end of May, and in June, the female lays her eggs, choosing the crevices of the twigs, and as soon as the larva is produced, it penetrates to the centre to feed upon the pith, eating its way downwards until it has attained its full size. It then changes to its pupa state, and becomes fur- nished with serrated short spines, which enable it to ascend to an opening in the side of the shoot previously prepared by the larva. From this opening the moth escapes. The caterpillar is fleshy, of a dirty-white colour, with a scarcely traceable dorsal line; it has sixteen feet, two anal, six pectoral, and eight abdominal; the head and four homy spots are bright brown. The moth is brilUant black, inclining to purplish, which contrasts well with the yellow lines en- circling the body, one of which forms a collar to the neck; and two longitudinal strips run across the thorax, while there are three similar strips upon the abdomen of the female, and four on the male. The wings are transparent, with dark nervures, and surrounded with a purple margin, sprinkled with golden scales ; the supe- rior wings toward their apex are of a golden colour, uniting with a dark lunate spot on the disc, enclosing a transparent ovate spot, across which fo
