Dr. C. B. Williams and Mrs. K. Grant. {Communicated by Captain T. 

 Dannreuther .) — The Insect Immigration Enquiry, with special reference 

 to the North-Western Area. 



Observations conducted over a series of years yield definite evidence of 

 the migrating instinct of certain well-known species of butterflies and moths 

 and indicate that the immigration takes place over a wide area and in a 

 uniform direction. 



The observations have been conducted by members of local scientific 

 societies throughout England and Wales, and by lighthouse and lightship 

 keepers who have rendered valuable assistance in collecting and recording 

 the arrival of specimens around the coasts ; the records, usually accom- 

 panied by specimens and essential information as to date, time, prevailing 

 wind direction, etc., entered on special cards provided for the purpose, 

 are sent to the Rothamsted Experimental Station, where they are analysed 

 and collated. 



There is, however, a lack of observers in the North-Western Area, where 

 sufficient information is not at present available to confirm the extent of 

 the migration and its prevalence and distribution ; and members of local 

 societies willing to assist are invited to communicate for further particulars 

 with the Secretary of the Insect Immigration Committee (South-Eastern 

 Union of Scientific Societies), Captain T. Dannreuther, Windycroft, 

 Hastings, Sussex. 



The following resolutions were considered and passed by the Delegates : 



To request the Council of the British Association to support the Council 

 for the Preservation of Rural England in its endeavour to stimulate His 

 Majesty's Government to consider and take action upon the Report of 

 the Government Committee on National Parks. 



To request the Council of the British Association to bring to the notice 

 of the respective Councils for the Preservation of Rural England, Scotland, 

 and Wales the increasing menace to health and amenity of rubbish 

 dumping in places of natural beauty and scientific interest ; and to request 

 the said Councils to make representation to the responsible administrative 

 authorities concerned with a view to its mitigation.
