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
