species, and it received the common name of the Portland 

 Moth, not from the Isle of Portland, where it is very scarce, 

 but from the circumstance that it formed one of the principal 

 treasures of the collection of the Duchess of Portland, who 

 seems to have been the first to rear it in this country. 

 Although rare at Portland, it is found more freely in suitable 

 places elsewhere on the Dorset coast, and on the north and 

 south coast of Devon ; also, I believe, on Hayling Island, 

 Hants, but records appear to be wanting elsewhere in the 

 extreme south of this country. It is not rare on the coast of 

 Norfolk and Suffolk and is even rather common on those of 

 Yorkshire, Lancashire, Cheshire, and the Isle of Man. In 

 Wales it has been taken on the Towyn Sands, Merionethshire, 

 near Neath, and at Tenby. On the Breck-sands of Norfolk 

 and Suffolk it seems still to survive, though in extremely 

 small numbers, but this may not be a survival of an ancient 

 race, since the species seems to have an occasional habit of 

 making rather long flights at night. Thus in the neighbour- 

 hood of King's Lynn an occasional specimen is found at 

 heather bloom several miles from the sea ; very rarely 

 examples have been met with near Stowmarket, Suffolk ; and 

 once it has even been taken at light at Cambridge. In 

 North Wales too a specimen was taken quite recently by 

 Colonel Partridge, at light, on the hills fully six miles from 

 the sea. In Scotland the only record in the south-west 

 appears to be at Ardrossan on the Frith of Clyde, northward 

 in Sutherlandshire, and on the east it extends as far north 

 as the Culbin Sands, Morayshire. On the Irish coast more 

 widely distributed and probably to be found in every exten- 

 sive waste of sandhills ; it is recorded from various parts 

 of the Dublin coast, Wicklow, Wexford, Waterford, Kerry, 

 Sligo, Donegal, Londonderry, Antrim, and Down. Abroad 

 it is said to be widely distributed in Central Europe, and to 

 be found in Livonia and Siberia.
