In this work, families are named and numbered as they appear in Kloet and Hincks (1972), and these authors have been followed for species synonyms with appropriate modifications due to more recent work. Species numbers follow those in Bradley and Fletcher (1979), the number in brackets following the Bradley and Fletcher number is a cross-reference to Robson’s Catalogue. Unfortunately Robson’s numbering system began afresh for each family instead of running consecutively, so that the reader must consult the latter work if he wishes to compare Robson’s notes with our own. We have made every effort, however, to summarise the main points of Robson’s case, in situations where his evidence or interpretations differ markedly from our own, so that our work can be regarded as complete in its own right.

We have split the list of species into two parts and dealt with the Macrolepidoptera in this Part 1, which is essentially the second part of the system of classification, as there are some problems associated with the Microlepidoptera not yet resolved. This group, forming Part 2, will contain some families, namely Hepialidae, Zygaenidae, and Sesiidae, which traditionally (because of the size of the insects and irrespective of their position within the system of classification) have been described in other works on the Macrolepidoptera. Watsonian vice county numbers are used frequently in the text Thus vc 66 is Durham County (including that part of Tyne and Wear south of the Tyne and that part of Cleveland north of the Tees), vc 67 is South Northumberland (from the vc 66 border to the River Coquet and including that part of Tyne and Wear north of the Tyne) and vc 68 is North Northumberland (between the Coquet and the Scottish Border).

On the distribution maps vice county boundaries are shown. Each small division represents a tetrad or 2km. square. In them are dots, noughts and/or crosses representing the records. Dots signify records made before the year 1900, noughts between 1900 and 1950. and crosses from 1950 to present.

The abbreviations TCD and JDP used throughout the text refer to the authors, and MBGBI refers to the various volumes of ‘The Moths and Butterflies of Great Britain and Ireland’ (1979 and 1983). Each author has been responsible for assembling his own county records (i.e. TCD for Durham and JDP for Northumberland). There after TCD has written the notes on species 1525-1970 and JDP those on species 1971-2405, with appropriate further consultation.
