SOME FARM INSECTS OBSERVED IN THE ABERYSTWYTH AREA, 1913-1916. By C. L. WALTON, M.Sc. {Departments of Agriculture and Zoology, University College of Wales, Aberystwyth.) The following insects were collected and observed during the pro-gress of a Survey of Agricultural Zoology which I recently carried out in the Aberystwyth Area. The area examined comprised some 250 sq. miles, and included the Plynlymon mountain mass ; the wooded river valleys and foot hills ; the wide peat bog bordering the southern bank of the Dyfi Estuary ; the cultivated region of hill and valley about the coast and lower reaches of the rivers Rheidol and Ystwyth ; and a region of high, bare, ill-drained hills (largely coated with boulder clay) lying to ihe S.E. and within the Teifi watershed. The predominant features of the whole include slaty and grit rocks, overlaid to a very large extent by peat and boulder clay ; a moist climate ; an Agriculture in which sheep farming predominates, followed in order by cattle raising, dairying and horse breeding. Corn and root growing are seldom more tlian subsidiary in value; while fruit growing hardly exists; and market gardening, to a limited extent, around Aberystwyth only. During the progress of the Survey little attention was paid to any gardens other than those of the farmers, and in the mountains few farms can boast a garden worthy of the name. In many groups the lists are by no means complete, the scope of the Survey was a wide one, and special attention was given to the Liver Rot of sheep. The work was carried out under a grant from the Board of Agricultiue and Fisheries. Cabbage Butterflies. Early in September, 1914, I left Aberystwyth and travelled down the coast of Cardigan Bay (chiefly on foot) into Pembrokeshire and visited several parts of that county. Up to the time of leaving the Survey
